<System configuration>
FIG. 1 is a diagram showing the configuration of a diagnostic system 1. As shown in FIG. The diagnostic system 1 functions in relation to the business flow of hydraulic unit manufacturers, vehicle manufacturers, vehicle body manufacturers, and transportation companies. FIG. 1 shows the processing flow including the business flow in each of these manufacturers or companies together with step numbers.

A vehicle manufacturer manufactures the body of the cargo handling vehicle 10 . The body of the cargo handling vehicle 10 is also called a chassis. A vehicle body includes, for example, a body including a seat and a luggage carrier, also called body. The vehicle manufacturer delivers the manufactured vehicle bodies to various bodywork manufacturers A, B, . . . of different scales (step S1).

A hydraulic unit manufacturer manufactures the hydraulic unit 14, which is an example of a unit that constitutes at least part of the body. A management device 100 is arranged at a hydraulic unit manufacturer. The hydraulic unit manufacturer manages each manufactured hydraulic unit 14 with a serial number in the management device 100 . This serial number is called the unit ID. A communication device 80 storing a unit ID is mounted on the hydraulic unit 14 . Each hydraulic unit 14 can be identified by the unit ID. The communication device 80 has a function of communicating with the management device 100 . The unit ID is an example of first identification information. The hydraulic unit manufacturer is the manager of the diagnostic platform described below.

The hydraulic unit manufacturer delivers the hydraulic unit 14 on which the communication device 80 is mounted to various vehicle body manufacturers A, B, . . . of different scales (step S2).

The bodybuilder mounts the hydraulic unit 14 on the vehicle body (step S3). Various types of cargo handling vehicles 10 such as gate cars, wing cars, and forklifts are thereby assembled. FIG. 1 shows a gate car as an example of the cargo handling vehicle 10 .

The vehicle body manufacturer attaches the sensor 40 to various devices other than the hydraulic unit, such as the battery unit and the engine unit, which constitute the cargo handling vehicle 10 (step S4). The vehicle body manufacturer installs the sensors 40 required for each vehicle type of the cargo handling vehicle 10 at required locations. The bodybuilder may attach the sensor 40 to various parts that make up the hydraulic unit 14 . Alternatively, the manufacturer of the component other than the hydraulic unit attaches the sensor 40 required for the component to the required location. Alternatively, the vehicle manufacturer may install the sensors 40 required for the vehicle at necessary locations. The diagnostic system 1 according to the present embodiment diagnoses the states of various devices constituting the cargo handling vehicle 10 based on the signals output by these sensors 40 . Body manufacturers and component manufacturers will make use of their own know-how to devise the position to install the sensor 40 for each vehicle type. Note that the hydraulic unit manufacturer may attach various sensors 40 to the hydraulic unit 14 in advance. In the following, for the sake of simplification of explanation, bodywork manufacturers and component manufacturers are simply referred to as bodywork manufacturers.

The bodybuilder connects the wiring of the sensor 40 to the communication device 80 (step S5).

The bodybuilder delivers the assembled cargo handling vehicle 10 to various transportation companies X, Y, . . . of different scales (step S6).

The transportation company applies for registration of the cargo handling vehicle 10 to a national agency. The transportation company notifies the vehicle body manufacturer of the delivery source of the vehicle registration number issued by the registration application (step S7). For example, the person in charge of the transportation company may use a computer to transmit information that can identify the cargo handling vehicle 10 and the vehicle registration number to the computer of the bodybuilder that is the delivery source.

The bodybuilder determines whether or not to provide the diagnostic service for the cargo handling vehicle 10 having the notified vehicle registration number (step S8). By accessing the management device 100 , the vehicle body manufacturer can diagnose the state of the cargo handling vehicle 10 based on the sensor 40 attached to the cargo handling vehicle 10 . The bodybuilder determines whether or not to provide the diagnostic service for each of the cargo handling vehicles 10 delivered to the transportation company.

The hydraulic unit manufacturer provides diagnostic services to the bodybuilder for a fee. The bodybuilder needs to pay a service fee to the hydraulic unit manufacturer in order to use the diagnostic service. The service charge is, for example, an amount corresponding to the number of cargo handling vehicles 10 for which the diagnostic service is provided. If all the cargo handling vehicles 10 delivered to the transportation company are set as targets of the diagnostic service, the service charge will be high. For this reason, the bodybuilder selects the target cargo handling vehicle 10 so that the diagnostic service can be performed effectively, taking into consideration the various circumstances of the shipping company with which the bodybuilder does business.

The criteria for whether or not to provide the diagnostic service to the shipping company will differ depending on the bodybuilder A, B, . . . For example, bodybuilder A may set standards according to the size of the shipping company. The vehicle body manufacturer B may set a standard according to the sales amount or the number of deliveries of the cargo handling vehicle 10 to the transportation company.

Out of a plurality of shipping companies with which the bodywork manufacturer C does business, the vehicle body maker C selects the shipping companies that are likely to use the cargo handling vehicles 10 frequently, and applies the diagnostic service to the cargo handling vehicles 10 that have been delivered to the extracted shipping companies. may be targeted. In general, it is expected that the frequency will be higher for a shipping company that receives more orders for delivery services.

Bodybuilder D selects a transportation company that seems to tend to use the hydraulic unit 14 frequently among the multiple transportation companies with which the vehicle body maker D does business, and selects the cargo handling vehicle 10 that is delivered to the transportation company as a target vehicle for the diagnosis service. I might. The vehicle body maker E may ask the transportation company for a request for the diagnostic service, and may select the cargo handling vehicle 10 delivered to the transportation company requesting the diagnostic service as the target vehicle for the diagnostic service.

The vehicle body manufacturers A, B, . Of course, the bodybuilder need not make that decision for each carrier. For example, among a plurality of cargo handling vehicles 10 delivered to the same transportation company, one or more specific cargo handling vehicles 10 may be target vehicles for the diagnostic service.

The diagnostic service may be, for example, a service of inspecting the cargo handling vehicle 10 at regular intervals. The diagnostic service may be a service for replacing parts of the cargo handling vehicle 10 at regular intervals. The bodybuilder may add to the diagnostic service a service that provides useful information on delivery operations using the cargo handling vehicle 10 .

After determining whether or not the diagnostic service is necessary for each cargo handling vehicle 10, the body manufacturer notifies the hydraulic unit manufacturer of various information regarding the cargo handling vehicle 10 (step S9). Various types of information include unit ID, bodybuilder ID, vehicle type ID, vehicle registration number, shipping company name, and necessity of diagnostic service. For example, a bodybuilder's person in charge may use a computer to transmit these various types of information to the hydraulic unit manufacturer's computer.

The bodybuilder ID included in various types of information is identification information for identifying the bodybuilders A, B, . . . . The hydraulic unit maker can identify the body maker involved in the installation of the hydraulic unit 14 by the body maker ID associated with the cargo handling vehicle 10 . The bodybuilder ID is an example of the second identification information.

The vehicle type ID included in various types of information is identification information for identifying the vehicle type of the cargo handling vehicle 10 provided by the bodywork manufacturer. The vehicle body manufacturer identifies the vehicle type of the cargo handling vehicle 10 by the vehicle type ID. The vehicle type ID is an example of the third identification information.

The hydraulic unit manufacturer registers various information notified from the bodywork manufacturer in the management device 100 (step S10). The management device 100 includes a processor 101 and memory 102 . Management device 100 is an example of a diagnostic device. The management device 100 constitutes a server. For example, the processor 101 registers various types of information in the memory 102 according to information input by the administrator. Processor 101 is an example of a control device. The processor 101 may receive these various types of information from the bodybuilder's computer and register the received various types of information in the memory 102 .

A diagnostic platform and a diagnostic result notification system are built in the memory 120 . The diagnostic platform provides an environment for setting various settings used for diagnosing the cargo handling vehicle 10 to the vehicle body manufacturer. The diagnosis result notification system notifies the hydraulic unit manufacturer, bodywork manufacturer, or shipping company of various diagnosis results based on the settings of the diagnosis platform.

The vehicle body manufacturer uses the diagnostic platform to set diagnostics for each vehicle type of the cargo handling vehicle 10 (step S11). The diagnosis settings include information about the device to be diagnosed, the sensor 40 used for diagnosis, and thresholds used as criteria for determination. By using the diagnostic platform, bodybuilders can make diagnostic settings that make use of their know-how without having to develop their own systems. By using the diagnostic result notification system, the bodybuilder can acquire diagnostic result information according to the contents set on the diagnostic platform. The information of the diagnosis result is hereinafter referred to as diagnosis information.

The transportation company operates a transportation business using the delivered cargo handling vehicle 10 . The operating rate of the cargo handling vehicle 10, the travel distance, the operating rate of the hydraulic unit 14 mounted on the cargo handling vehicle 10, etc. differ depending on the scale, form, business situation, etc. of the transportation company. The sensor 40 attached to the cargo handling vehicle 10 detects various information according to the location where the sensor 40 is attached.

A communication device 80 mounted on the hydraulic unit 14 has a function of communicating with the management device 100 via a network 50 such as the Internet. The sensor 40 attached to the cargo handling vehicle 10 transmits the detected value to the communication device 80 . The communication device 80 transmits the detection information of the sensor 40 to the management device 100 (step S12). The management device 100 collects the detection information of the sensor 40 for each hydraulic unit ID of the cargo handling vehicle 10 to which the sensor 40 is attached. Hereinafter, the detection information of the sensor 40 is also referred to as sensor detection information.

The management device 100 collects the sensor detection information sent from the cargo handling vehicles 10 for which diagnostic service setting is required. The management device 100 does not collect sensor detection information sent from the cargo handling vehicle 10 for which the diagnostic service is set to no service. This is because sensor detection information is used for diagnostic services for each cargo handling vehicle 10 .

The management device 100 provides diagnostic information of the cargo handling vehicle 10 to the bodywork manufacturer (step S13). Diagnosis information of the cargo handling vehicle 10 is provided to the bodybuilder by the diagnosis result notification system. The diagnostic information of the cargo handling vehicle 10 includes, for example, failure information of the hydraulic unit 14 mounted on the cargo handling vehicle 10, information notifying a voltage drop of the battery of the cargo handling vehicle 10, and the like. The type of diagnostic information varies depending on the bodybuilder's diagnostic settings.

The diagnostic information provided by the management device 100 is information generated for each cargo handling vehicle 10 . The management device 100 provides the bodywork maker A with diagnostic information of the cargo handling vehicle 10 corresponding to the hydraulic unit 14 delivered to the bodywork maker A. FIG. The management device 100 provides the vehicle body maker B with diagnostic information of the cargo handling vehicle 10 corresponding to the hydraulic unit 14 delivered to the vehicle body maker B. FIG.

The management device 100 provides the bodywork maker with diagnostic information of the cargo handling vehicle 10 for which diagnostic service setting is required. The management device 100 does not provide the vehicle body maker with the diagnostic information of the cargo handling vehicle 10 for which the diagnostic service is set to "no service". In other words, the management device 100 provides diagnostic information only for the cargo handling vehicles 10 for which the bodybuilder has made diagnostic services.

The management device 100 transmits the diagnostic information to the terminal device of the bodybuilder. The management device 100 may transmit the diagnostic information to the portable terminal of the person in charge of the bodybuilder. The management device 100 may transmit the diagnostic information to a terminal device arranged at the transportation company of the cargo handling vehicle 10 . The management device 100 may transmit diagnostic information to the cargo handling vehicle 10 . A communication terminal for receiving diagnostic information may be installed in the cargo handling vehicle 10 . The management device 100 may transmit diagnostic information to a mobile terminal possessed by a driver of the corresponding cargo handling vehicle 10 .

Based on the diagnostic information, the bodybuilder grasps the state of the cargo handling vehicle 10 delivered to the transportation company. The bodywork manufacturer takes measures according to the diagnostic information of the cargo handling vehicle 10 (step S14).

For example, based on the diagnostic information of the cargo handling vehicle 10 delivered to the transportation company X, the vehicle body manufacturer A grasps that the drive count of the hydraulic unit 14 mounted on the cargo handling vehicle 10 exceeds the reference value. . In this case, a worker of vehicle body maker A may go to transportation company X and inspect hydraulic unit 14 . For example, on the basis of the diagnostic information of the cargo handling vehicle 10 delivered to the transportation company Y, the vehicle body manufacturer B recognizes that the battery voltage of the cargo handling vehicle 10 is abnormally low. In this case, a worker of vehicle body maker B may go to transportation company Y to inspect the battery.

By utilizing the diagnostic platform and diagnostic reporting system, bodybuilders can provide value-added services to shipping companies. As a result, the vehicle body manufacturer has the advantage of being able to increase sales of the cargo handling vehicle 10 .

The hydraulic unit manufacturer charges the bodybuilder a service fee in return for providing the diagnosis platform and diagnosis result notification system to the bodybuilder (step S15). The service charge varies, for example, depending on the number of cargo handling vehicles 10 set for diagnostic service.

For example, out of 50 cargo handling vehicles delivered by the vehicle body manufacturer A to the transportation company X, 40 vehicles are set to require diagnostic service, and 30 cargo vehicle vehicles delivered by the vehicle body manufacturer A to the transportation company Y are set to require diagnostic service. Assume that 15 of them are set to require diagnostic service. In this case, the hydraulic unit manufacturer bills the bodybuilder A for a service charge equivalent to 55 units. The hydraulic unit manufacturer thus bills the bodybuilders A, B, . . . for service charges.

The bodybuilder charges the transportation company a service fee in return for providing the diagnostic service (step S16). The service charge varies, for example, depending on the number of cargo handling vehicles 10 set for diagnostic service. The bodybuilders A, B, .

<Data Managed by Management Device 100>
FIG. 8 is a diagram showing an example of data managed by the management device 100. As shown in FIG. In particular, FIG. 8 shows data stored in the management device 100 in association with the unit ID.

The management device 100 stores the unit ID in association with the bodybuilder ID, vehicle type ID, vehicle registration number, and shipping company name. A unit ID is a unique number. The management device 100 can identify each hydraulic unit 14 by the unit ID. The hydraulic unit 14 is mounted on the cargo handling vehicle 10 . A unit ID is stored in the communication device 80 mounted on the hydraulic unit 14 . Therefore, the management device 100 can identify each cargo handling vehicle 10 by the unit ID.

The management device 100 can specify the delivery destination of the hydraulic unit 14 by the bodybuilder ID. The management device 100 can specify the vehicle type of the cargo handling vehicle 10 for each unit ID based on the vehicle type ID. The management device 100 can identify the cargo handling vehicle 10 to which the hydraulic unit 14 is attached by the vehicle registration number. The management device 100 can specify the delivery destination of the cargo handling vehicle 10 by the name of the transportation company.

The management device 100 can identify the bodybuilder by the alphabet included in the bodybuilder ID. For example, A corresponds to bodybuilder A and B corresponds to bodybuilder B. The four-digit number on the right of the alphabet is a number for identifying each hydraulic unit 14 in the vehicle body manufacturer. This number may be omitted if it is only for the purpose of identifying the bodybuilder. The data shown in FIG. 8 includes the bodybuilder name corresponding to the bodybuilder ID. A company and B company correspond to it.

The management device 100 can identify the vehicle manufacturer by the alphabet included in the vehicle model ID, and identify the vehicle model of the vehicle manufacturer by the number included in the vehicle model ID. For example, Ac corresponds to bodybuilder A and Bc corresponds to bodybuilder B. The four-digit number on the right side of the alphabet is a number corresponding to the vehicle type of each vehicle manufacturer.

The data shown in FIG. 8 includes service flags associated with unit IDs. A service flag is a flag for identifying the presence or absence of a diagnostic service. In the data shown in FIG. 8, service flags corresponding to unit IDs 0000001 to 0000005, 0000007, and 0000008 are set to ON. This means that the cargo handling vehicle 10 identified by the corresponding unit ID is the object of the diagnostic service. In the data shown in FIG. 8, the service flags corresponding to unit IDs 0000006, 0000009, and 00000010 are set to OFF. This means that the cargo handling vehicle 10 identified by the corresponding unit ID is not subject to diagnostic services.

The management device 100 sets the service flag to ON or OFF according to the instruction input by the administrator.

The data shown in FIG. 8 includes diagnostic information. The management device 100 generates diagnostic information for unit IDs for which the service flag is set to ON. The management device 100 does not generate diagnostic information for a unit ID whose service flag is set to OFF. In FIG. 8, the description "No Service" means that the management device 100 does not generate diagnostic information.

Note that FIG. 8 shows data in a state before the management device 100 generates diagnostic information. Therefore, the specific contents of diagnostic information are not shown in FIG. A specific example of the diagnostic information has already been mentioned, so the description will not be repeated here.

<Diagnostic setting information managed by vehicle type ID>
FIG. 9 is a diagram showing an example of diagnostic setting information managed by the management device 100 for each vehicle type ID. As shown in FIG. 9, the management device 100 stores diagnostic setting information for each vehicle type ID. For example, the management device 100 stores "diagnosis type 1 (arbitrary name setting)" corresponding to the vehicle type ID "Ac0001". It should be noted that characters arbitrarily input by the bodybuilder A at the time of setting are displayed in the "arbitrary name setting" portion. For example, the vehicle body maker A may input the name of the vehicle type in the "arbitrary name setting" section. The management device 100 uses “diagnosis type 1 (arbitrary name setting)” as a label and stores detailed setting data corresponding to the label in the memory 102 .

<Diagnostic setting screen>
FIG. 10 is a diagram showing a diagnostic setting screen 210 provided by the diagnostic platform. FIG. 11 is a diagram for explaining diagnostic categories that can be selected on the diagnostic setting screen 210. As shown in FIG. The diagnostic platform provides an environment for setting diagnostics for each bodybuilder. For example, FIG. 10 shows a diagnostic setting screen 210 displayed on terminal device 200 of bodybuilder A. As shown in FIG. A diagnosis setting screen 210 displays a plurality of setting sheets 211 for setting diagnosis for each vehicle type ID. In the setting sheet 211, determination conditions for diagnosing the state of the cargo handling vehicle 10 are registered according to the operation of the person in charge of the bodywork manufacturer.

At the top of the setting sheet 211, there is a field for entering the name of the diagnosis type. The bodybuilder can enter any name in this field. This name is reflected in "diagnosis type 1 (arbitrary name setting)" shown in FIG. As already explained, for example, the bodybuilder can enter the name of the vehicle type in this field.

At the top of the setting sheet 211, a column for entering the vehicle type ID is provided. The person in charge of the bodybuilder inputs the vehicle model ID to be set in the setting sheet 211 in this column. The diagnosis platform identifies the cargo handling vehicle 10 to which the settings are applied based on the vehicle type ID entered in this field.

Specifically, when the management device 100 receives the sensor detection information and the unit ID from the cargo handling vehicle 10, the management device 100 identifies the vehicle type ID stored in correspondence with the unit ID. The management device 100 reads diagnostic settings corresponding to the vehicle type ID. The management device 100 processes the received sensor detection information based on the read diagnostic settings. As a result, the setting set in the setting sheet 211 is applied to the diagnosis of the cargo handling vehicle 10 of the corresponding model.

The setting sheet 211 includes a column for selecting a diagnostic category (diagnostic category), a column for inputting a diagnosis name (diagnosis name), a column for specifying the channel of the sensor 40 used for diagnosis (first sensor, second sensor, . . . ), and a channel. A field for specifying a threshold corresponding to (first sensor threshold, second sensor threshold, etc.), a field for specifying time (time), a field for inputting a diagnosis target (diagnosis), and a field for inputting the number of times of diagnosis (number of times of diagnosis )including. In the setting sheet 211, determination conditions used for diagnosis can be input for each row.

In the field for selecting the diagnosis category, operating diagnosis, monitoring diagnosis, frequency diagnosis, etc. are selected. The diagnostic categories will now be described with reference to FIG. In operation diagnosis, a diagnosis target is diagnosed by sensing in a relatively short period (for example, 0.5 sec). Channels of the first channel group 81 shown in FIG. 5 are used for diagnostics during operation. In monitoring diagnosis, a diagnosis target is diagnosed by sensing with a relatively long period (for example, 180 sec). Channels of the second channel group 82 or the third channel group 83 shown in FIG. 5 are used for monitoring diagnosis.

Diagnosis during operation may be selected when diagnosing that an event corresponding to the diagnosis name has occurred at a stage where the detected value of the sensor 40 continuously exceeds the threshold for a relatively short period of time. The monitoring diagnosis may be selected when diagnosing that an event corresponding to the diagnosis name has occurred when the detected value of the sensor 40 continues to exceed the threshold for a relatively long period of time. Each length of time is entered in the time column shown in FIG.

As shown in FIG. 11, the frequency diagnosis targets the number of times an event is detected by sensing. For example, in FIG. 10, the line with the diagnosis name "CCC replacement time" is classified into the category of frequency diagnosis. "DD operation" is entered in the diagnosis target column. "100 times" is entered in the number of times of diagnosis column. Therefore, the diagnostic name "CCC replacement time" is determined to be the replacement time for the device "CCC" on the condition that the number of times the event "device DD operates" has reached 100 times. Corresponding to diagnose. There is no need to enter the sensor 40 channel, threshold, and time in the count diagnostic row.

An arbitrary diagnosis name is entered in the diagnosis name column. For example, if the name of one device that constitutes the cargo handling vehicle 10 to be diagnosed is "AAA", the person in charge of the bodybuilder can specify any arbitrary name such as "AAA failure", "AAA abnormality", and "AAA replacement time". A diagnosis name can be entered in the Diagnosis Name field.

A plurality of fields for designating the channel and threshold value of the sensor 40 used for diagnosis are provided in each row. FIG. 10 shows part of the columns for specifying channels and thresholds. For example, the first sensor column corresponds to the first sensor threshold value column. The second sensor column corresponds to the second sensor threshold value column. The third sensor column corresponds to the third sensor threshold value column. The channel of the communication device 80 is entered in each sensor column. A threshold value for determining the detected value of the corresponding sensor 40 is entered in each sensor threshold column.

The person in charge of the bodybuilder may input only one channel or a plurality of channels as the channel of the sensor 40 used for diagnosis. For example, only the V1 channel is entered in the "AAA failure" row in FIG. The V2 and V3 channels are entered in the "BBB Abnormality" row in FIG. For example, when channels V2 and V3 are input, the detected value of sensor 40 corresponding to V2 exceeds threshold 10 (Volt) and the detected value of sensor 40 corresponding to V3 exceeds threshold 20 (Volt). If exceeded, the criteria for determining that the event to be diagnosed has occurred are met.

In the setting sheet 211, the person in charge of the bodybuilder can set the first sensor, the second sensor, . The diagnostic platform accepts an operation of inputting the first sensor threshold value, the second sensor threshold value, . . . on the setting sheet 211 . For example, the first sensor threshold is a value for determining whether the detection value of the first sensor satisfies the first condition. For example, the second sensor threshold is a value for determining whether the detection value of the second sensor satisfies the second condition. In the setting sheet 211, "Time" is a value for determining whether the duration of the first condition or the second condition satisfies the third condition that satisfies the predetermined determination condition. Further, in the setting sheet 211, the "diagnosis frequency" is a value for determining whether the number of times the first condition or the second condition is satisfied satisfies the third condition that satisfies the predetermined determination condition.

The person in charge of the vehicle body manufacturer uses the number of setting sheets 211 corresponding to the number of required vehicle types to perform diagnostic settings for each vehicle type. As a result, diagnostic setting information for each vehicle type is registered in the diagnostic platform.

FIG. 18 is a flow chart showing the flow of processing relating to registration of the unit ID, bodybuilder ID, and vehicle registration number, and setting of the service flag. Processing based on this flowchart is executed by the management device 100 .

First, the management device 100 determines whether or not a unit ID has been input (step S101). If there is no unit ID input, the management device 100 advances the process to step S103. When the unit ID is input, the management device 100 registers the input new unit ID (step S102). For example, management device 100 registers the unit ID in memory 102 by storing the input unit ID in memory 102 .

The management device 100 may accept input of the unit ID from the keyboard. The management device 100 may collectively register a plurality of IDs recorded on a recording medium or a plurality of IDs received via a network.

Next, the management device 100 determines whether or not the bodybuilder ID to be linked to the unit ID has been input (step S103). If there is no input of the bodybuilder ID, the management device 100 advances the process to step S105. When the bodybuilder ID to be linked to the unit ID is input, the management device 100 links the input bodybuilder ID to the corresponding unit ID and registers it in the memory 102 (step S104).

Next, the management device 100 determines whether or not the vehicle type ID to be linked to the unit ID has been input (step S105). If the vehicle type ID is not input, the management device 100 advances the process to step S107. When a vehicle model ID to be linked to the unit ID is input, the management device 100 stores the input vehicle model ID in the memory 102 by linking it to the corresponding unit ID (step S106).

Next, the management device 100 determines whether or not the vehicle registration number associated with the unit ID has been input (step S107). If there is no vehicle registration number input, the management device 100 advances the process to step S109. When the vehicle registration number to be associated with the unit ID is input, the management device 100 associates the input vehicle registration number with the corresponding unit ID and registers it in the memory 102 (step S108).

Next, the management device 100 determines whether or not there is an input indicating that service is required for the unit ID (step S109). More specifically, the management device 100 determines whether or not an input specifying a unit ID and an input instructing to turn on the service flag for that unit ID have been received. For example, the initial setting of the service flag is OFF. In step S109, it is determined whether or not an input to turn on the initial setting has been received.

If there is no such input, the management device 100 advances the process to step S111. When receiving such an input, the management device 100 changes the service flag of the corresponding unit ID from OFF to ON (step S110).

Next, the management device 100 determines whether or not an input to change the necessity of the service has been received (step S111). More specifically, the management device 100 determines whether or not there is an input to change the setting of the service flag. This input includes the unit ID whose setting is to be changed.

If there is no such input, the management device 100 ends the processing based on this flowchart. When receiving such an input, the management device 100 changes the service flag of the corresponding unit ID according to the input specification (step S112), and ends the process.

As the processing based on the flow chart described above is executed by the management device 100, various information shown in FIG. 8 is stored in the memory 102 of the management device 100 for each unit ID.

FIG. 19 is a flow chart showing the flow of diagnostic setting processing. Processing based on this flowchart is executed by the management device 100 and the terminal device 200 .

First, the terminal device 200 generates a diagnostic setting request and transmits the generated diagnostic setting request to the management device 100 (step S251). A diagnostic setting request is generated by operating the terminal device 200 by a person in charge of the bodybuilder. The diagnostic setup request includes the bodybuilder ID and password. The person in charge of the bodybuilder may make new diagnostic settings using the setting sheet 211 shown in FIG. 10, or may modify the already created diagnostic settings. When modifying diagnostic settings that have already been created, the person in charge of the bodybuilder includes the vehicle model ID in addition to the bodybuilder ID and password in the request for diagnostic settings.

The management device 100 determines whether or not a request for diagnostic settings has been received (step S201). If the request for diagnostic setting has not been received, the management device 100 terminates the processing based on this flowchart. When receiving the diagnostic setting request, the management device 100 determines whether or not the password included in the diagnostic setting request is correct (step S202). The management device 100 manages passwords for each bodybuilder ID. If the password is incorrect, the management device 100 ends the processing based on this flowchart.

If the password is correct, the management device 100 determines whether a new diagnostic setting is requested (step S203). The management device 100 generates new diagnostic setting data when a new diagnostic setting is requested (step S204). Next, the management device 100 transmits the generated diagnostic setting data to the terminal device 200 (step S205). As a result, the diagnostic setting screen 210 shown in FIG. 10 is displayed on the terminal device 200 .

Next, the terminal device 200 receives an operation for inputting diagnostic settings by the person in charge (step S252). The management device 100 determines whether setting completion information has been received from the terminal device 200 (step S206). The management device 100 continues the process of step S206 until receiving the setting completion information. Before long, the operation of inputting diagnostic settings on the terminal device 200 ends. Then, the person in charge performs a setting completion operation on the terminal device 200 . Upon receiving the setting completion operation, the terminal device 200 transmits setting completion information to the management device 100 (step S253). When the setting completion information is received, the management device 100 registers the input diagnostic setting in the memory 102 and ends the process (step S207). This creates a new diagnostic setting.

The management device 100 determines NO in step S203 when it is requested to modify the diagnostic settings that have already been created. In this case, management device 100 uses the vehicle type ID included in the diagnostic setting request to read diagnostic setting data to be corrected from memory 102 (step S208). Next, the management device 100 transmits the read diagnostic setting data to the terminal device 200 (step S205).

The terminal device 200 accepts an operation for inputting diagnostic settings by the person in charge in the same way as when creating new diagnostic settings (step S252). The management device 100 determines whether setting completion information has been received from the terminal device 200 (step S206). The management device 100 continues the process of step S206 until receiving the setting completion information. Eventually, the operation of inputting the diagnostic settings (the operation of updating the settings) on the terminal device 200 ends. Then, the person in charge performs a setting completion operation on the terminal device 200 . Upon receiving the setting completion operation, the terminal device 200 transmits setting completion information to the management device 100 (step S253). When the setting completion information is received, the management device 100 registers the input diagnostic setting in the memory 102 and ends the process (step S207). This updates the diagnostic settings.

The above-described flowchart constitutes a registration unit for registering determination conditions in the platform. By the functioning of the registration unit, the person in charge of the bodybuilder determines the determination conditions for diagnosing the state of the mobile body (parts mounted on the mobile body, etc.), operates the terminal device 200, Judgment conditions can be set. Alternatively, the person in charge of the vehicle body manufacturer determines the judgment conditions for diagnosing the state of the moving body, notifies the hydraulic unit manufacturer, who is the platform administrator, by e-mail or the like, and the hydraulic unit manufacturer The determination conditions may be set by operating the device. Here, among the plurality of sensors 40, for the sensor 40 arranged on the side of the hydraulic unit 14 shown in FIG. It may be configured as This is because the hydraulic unit manufacturer has more know-how about the determination conditions for the hydraulic unit than the vehicle body manufacturer. In this case, for example, a terminal device that can be operated by a person in charge of the hydraulic unit manufacturer can be connected to the management device 100 . The person in charge of the hydraulic unit manufacturer operates the terminal device to make diagnostic settings for the sensor 40 arranged on the hydraulic unit 14 side. With this configuration, the judgment conditions determined by the platform administrator (the person in charge of the hydraulic unit manufacturer) are registered as the judgment conditions for the sensors attached to the hydraulic equipment, and the sensors attached to the main body or components other than the hydraulic equipment are registered. A registration unit is configured to register the determination condition determined by the user (the person in charge of the vehicle body manufacturer, the person in charge of the component manufacturer, etc.) as the determination condition. The person in charge of the hydraulic unit manufacturer may directly operate the management device 100 to make diagnostic settings for the sensor 40 arranged on the hydraulic unit 14 side.

FIG. 20 is a flow chart showing the flow of processing relating to collection of sensor detection information and output of diagnostic information. Processing based on this flowchart is executed by the management device 100 .

First, the management device 100 receives sensor detection information and a unit ID from the communication device 80 of the cargo handling vehicle 10 (step S301).

Next, the management device 100 confirms the service flag corresponding to the unit ID (step S302). Next, based on the confirmation in step S302, the management device 100 determines whether the cargo handling vehicle 10 corresponding to the unit ID is an object for which the diagnosis service is provided (step S303).

If the cargo handling vehicle 10 corresponding to the unit ID is not an object for which the diagnosis service is provided, the management device 100 ends the process. As a result, sensor detection information corresponding to that unit ID is not collected by the management device 100 .

The management device 100 may collect the sensor detection information for each unit ID regardless of whether the cargo handling vehicle 10 corresponding to the unit ID is a target for which the diagnosis service is provided. In this case, it is desirable that the management device 100 restricts the diagnostic information of the cargo handling vehicle 10 not to be provided with the diagnostic service from being provided to the terminal device 200 of the bodybuilder.

When the cargo handling vehicle 10 corresponding to the unit ID is the object for which the diagnostic service is to be provided, the management device 100 collects the acquired sensor detection information for each unit ID (step S304). Next, management device 100 reads the vehicle type ID corresponding to the unit ID from memory 102 (step S305). Next, the management device 100 reads diagnostic settings corresponding to the vehicle type ID from the memory 102 (step S306). Next, the management device 100 generates diagnostic information based on the read diagnostic settings and sensor detection information (step S307). In other words, the management device 100 determines the acquired sensor detection information based on the diagnostic settings, and generates diagnostic information according to the diagnostic settings. Next, the management device 100 stores the generated diagnostic information in the memory 102 by unit ID (step S308).

Next, the management device 100 outputs the generated diagnostic information (step S309). For example, management device 100 outputs diagnostic information to display device 150 . The management device 100 may output diagnostic information to the terminal device 200 of the bodybuilder via the network 50 . The management device 100 may output the diagnostic information via the network 50 to a portable terminal or the like of a person in charge of the bodywork manufacturer.

Next, the management device 100 determines whether or not there is an input instructing to output the data list (step S310). The administrator of the management device 100 inputs a command for instructing output of the data list from a keyboard or the like. In this case, the management device 100 determines YES in step S310.

The management device 100 outputs a data list of unit IDs when an instruction to output a data list is received (step S311). The output data list is displayed on display device 150 in the manner shown in FIG. 14, for example. The management device 100 may output the data list to a printer.

Next, the management device 100 determines whether or not there is an input instructing to output data with the service flag ON (step S312). The administrator of the management device 100 inputs a command to output data with the service flag ON from a keyboard or the like. In this case, the management device 100 determines YES in step S312.

When receiving an input instructing to output data with the service flag ON, the management device 100 selects the data of the unit ID with the service flag ON and outputs the selected data (step S313). The output data is displayed on the display device 150 in the manner shown in FIG. 15, for example. The management device 100 may output such data to a printer.

After outputting the data in step S313, or after determining NO in either step S310 or step S312, the management device 100 ends the processing based on this flowchart.

FIG. 21 is a flow chart showing the flow of processing relating to transmission of diagnostic information and service charges. Processing based on this flowchart is executed by the management device 100 .

First, the management device 100 determines whether or not a list information request has been received from the bodybuilder's terminal device 200 (step S401). The list information request includes the bodybuilder ID and password.

If the list information request has not been received, the management device 100 terminates the processing based on this flowchart. When receiving the list information request, the management device 100 determines whether or not the password included in the list information request is correct (step S402). If the password is incorrect, the management device 100 ends the processing based on this flowchart.

If the password is correct, the management device 100 transmits to the terminal device 200 the list information stored in the memory 102 corresponding to the requested bodybuilder (step S403). Thereby, a data list 201 shown in FIG. 16 is displayed on the terminal device 200, for example. The data list includes a detail button 203 and a service charge button 204 .

Next, the management device 100 determines whether or not operation information for the detail button 203 has been received (step S404). When the details button 203 displayed on the terminal device 200 is clicked, the operation information of the details button 203 is transmitted from the terminal device 200 to the management device 100 .

If the management device 100 has not received the operation information of the detail button 203, the processing proceeds to step S406. When receiving the operation information of the detail button 203, the management device 100 transmits diagnostic information of the unit ID corresponding to the operated detail button 203 to the terminal device 200 (step S405). As a result, for example, a diagnostic information screen 220 shown in FIG. 12 is displayed on terminal device 200 .

By looking at the screen of the terminal device 200, the person in charge of the bodywork manufacturer can confirm the diagnostic information of the selected cargo handling vehicle 10. FIG. The person in charge of the vehicle body manufacturer can refer to the diagnostic information and consider whether or not to go for maintenance of the target cargo handling vehicle 10 .

Next, the management device 100 determines whether or not operation information for the service charge button 204 has been received (step S406). When the service charge button 204 displayed on the terminal device 200 is clicked, the operation information of the service charge button 204 is transmitted from the terminal device 200 to the management device 100 .

If the management device 100 has not received the operation information for the service charge button 204, the processing based on this flow chart ends. When the management device 100 receives the operation information of the service charge button 204, the management device 100 calculates the service charge for each transportation company with which the bodybuilder does business (step S407). The service charge calculated here is the service charge that the bodybuilder can charge the transportation company. Furthermore, the management device 100 calculates a service charge for the bodybuilder (step S408). The service charge calculated here is the service charge charged to the bodybuilder by the hydraulic unit manufacturer.

Next, the management device 100 transmits the service charges calculated in steps S407 and S408 to the terminal device 200 (step S409), and ends the processing based on this flowchart. Thereby, the service charge 205 and the service charge 206 shown in FIG. 17 are displayed on the terminal device 200 .

By looking at the screen of the terminal device 200, the person in charge of the bodybuilder can see the service charge that the bodybuilder is charged by the hydraulic unit manufacturer and the service charge that the bodybuilder can charge to the shipping company. can be specified.

As described above, according to the present embodiment, the hydraulic unit manufacturer can provide a high-value-added diagnostic service to the vehicle body manufacturer and the transportation company. Here, the advantages of the hydraulic unit manufacturer providing comprehensive diagnostic services according to the present embodiment will be described in more detail.

Hydraulic unit manufacturers have a lot of technical know-how regarding the hydraulic unit 14 . Therefore, it is conceivable that the hydraulic unit manufacturer provides a service for diagnosing the state of the hydraulic unit 14 to the vehicle body manufacturer or transportation company for a fee. However, the hydraulic unit 14 is only one of many devices that make up the cargo handling vehicle 10 . By expanding the scope of the diagnostic service to include a large number of devices that make up the cargo handling vehicle 10, the hydraulic unit manufacturer can provide a more value-added diagnostic service to the bodywork manufacturer and the like.

However, hydraulic unit manufacturers do not necessarily have the technical know-how to diagnose the states of all the devices that make up the cargo handling vehicle 10 . Most of the technical know-how regarding the main body of the cargo handling vehicle 10 is often owned by the bodywork maker or the component maker other than the hydraulic unit maker, rather than by the hydraulic unit maker. Therefore, if a vehicle body maker or a component maker can independently develop a system for diagnosing the state of its own cargo handling vehicle 10, it may be possible to provide a high value-added diagnostic service to a transportation company. The vehicle body manufacturer or component manufacturer attaches the sensors 40 to appropriate locations of various devices of the cargo handling vehicle 10, and utilizes its own know-how to devise the conditions for determining the detection information of the sensor 40, thereby improving the cargo handling vehicle 10. It will be able to diagnose the condition of various constituent devices adequately.

However, bodybuilders or component manufacturers vary in size. Not all bodybuilders or component manufacturers have the technical capabilities and development funds to develop diagnostic services. Rather, many medium or small bodybuilders or component manufacturers may not have such technical capabilities and development funds. Therefore, even if the bodywork maker or the component maker has know-how about the position where the sensor 40 is installed and the determination conditions, it is difficult for the bodywork maker to independently develop a diagnostic system that utilizes the know-how.

Therefore, in the present embodiment, a hydraulic unit manufacturer provides a vehicle body manufacturer or a component manufacturer with a diagnostic platform capable of diagnosing the cargo handling vehicle 10 by making use of its own know-how. In the present embodiment, the unit ID of the hydraulic unit 14 is managed in association with the bodywork maker or component maker, the transportation maker, the cargo handling vehicle 10, and the vehicle type of the cargo handling vehicle 10. It is characterized by being able to identify information.

In this embodiment, the hydraulic unit manufacturer provides the vehicle body manufacturer or the component manufacturer with the communication device 80 that acquires the detection information of the sensor 40 and the diagnostic platform that enables diagnostic settings without hiring a system engineer. and provide.

According to the present embodiment, it is possible to provide a setting environment necessary for automatically diagnosing the state of the cargo handling vehicle 10 to the bodywork maker without requiring the bodywork maker to develop a system. can. Therefore, even if the bodybuilder does not have system design know-how, it is possible to make diagnostic settings based on their own know-how.

In the present embodiment, the hydraulic unit manufacturer can charge the vehicle body manufacturer the fee for the hydraulic unit 14 to which the fee for the communication device 80 is added and the service fee for the diagnostic service. As a result, the hydraulic unit manufacturer can improve profits compared to the case where the hydraulic unit without the communication device 80 is delivered to the vehicle body manufacturer. The cost of communication between the communication device 80 and the management device 100 may be included in the diagnostic service charge, or may be billed by the hydraulic unit manufacturer to the bodywork manufacturer separately from the diagnostic service charge.

In the present embodiment, the cargo handling vehicle 10 is used as an example of the mobile object. However, the mobile object is not limited to the cargo handling vehicle 10 . A general vehicle other than the cargo handling vehicle 10 may be the target of the diagnosis. In this case, the communication device 80 in which the unit ID is stored may be mounted on any unit mounted on a general vehicle. Alternatively, only the communication device 80 in which the unit ID is stored may be provided.

According to the present embodiment, the bodybuilder is provided with information that can identify whether or not the cargo handling vehicle 10 delivered to the shipping company is subject to the diagnostic service. Therefore, it is possible to reduce the burden on the bodywork maker to determine whether or not the cargo handling vehicle 10 delivered to the transportation company is subject to the diagnostic service.

Furthermore, according to the present embodiment, the service flag can be arbitrarily set for each cargo handling vehicle 10 . Therefore, the bodybuilder does not need to subject all the cargo handling vehicles 10 delivered to the transportation company to the diagnostic service. Therefore, the vehicle body manufacturer can reduce the number of cargo handling vehicles 10 to be subjected to the diagnostic service in consideration of various circumstances. Therefore, the bodybuilder can keep the service charge to be paid to the hydraulic unit manufacturer to an appropriate amount.

Further, according to the present embodiment, since the service charge for each transportation company is provided to the bodybuilder, the burden of managing the service fee for each transportation company can be reduced.

As described above, according to the present embodiment, it is possible to provide a high-quality service to the delivery destination of the cargo handling vehicle 10, and at the same time, it is possible to reduce the burden of managing information regarding the provision of the service.
