  The instruction acquisition intranet network 46 is an intranet network for acquiring a parts catalog and instruction manual of the work machine 11.

  In the management unit 15 and its surroundings in the work machine remote operation management system 10 shown in FIG. 1, data operating a website that is accessed from the customer personal computer 17pc and the in-house personal computer 19pc and is requested to obtain dynamic data. Web server of connection processing unit 22, internal database 23 for storing dynamic data acquired from work machine 11 through communication means and related data related to the dynamic data, and management server for managing internal database 23 And an external various information database 43 storing related data to be stored in the internal database 23, and a management server for managing the external various information database 43, the web of the data connection processing unit 22 The server retrieves the related data from the external information database 43 connected to itself and retrieves the internal data. And the dynamic data (operation data) stored in the internal database 23 together with related data (customer information) related thereto are reflected on the website, via the web server. The data transmission / reception data format is set to an XML data format, and at least the web server functions as a service requester and each server connected to the web server functions as a service provider.

  The management system of the management unit 15 is a technology that uses a so-called XML web service for the work machine remote operation management system 10 of the work machine 11. The XML web service is exchanged on the network by data exchange in the XML data format. A technology that links scattered applications. XML (eXtensible Markup Language) is one of the markup languages, and the biggest feature is that it is a language that can transmit and receive data between systems without depending on the platform of each system, and that the program can interpret. It can be used to send and receive data between servers.

  Then, SOAP (Simple Object Access Protocol) is known as a communication protocol that can use an object in the XML data format via a network (HTTP, which is generally used as a lower protocol, can be used). Therefore, for example, in the network environment connected by HTTP, using SOAP, for example, by sending the XML data from the first server to the second server on the network, the second server performs processing, and after the processing The XML data can be returned to the first server, and if the website is operated by the first server, the acquired data can be reflected on the website.

  The service requester and the service provider are both concepts on the XML web service. The service requester is a source of XML data for requesting data (for example, the first server), and the service provider is the transmission of the data. The other party server that returns the processed data to the service requester after the processing described in the data (for example, the second server).

  In the management unit 15, the web server of the data connection processing unit 22 functions as a service requester, and the management servers of the internal and external databases 23 and 43 connected thereto function as service providers. Therefore, the XML data format from the web server Each management server processes the command based on the command data, and returns the processed data to the web server. If the returned data is related data from the external information database 43, the web server transmits it as it is to the management server of the internal database 23 and stores it. If the returned data is dynamic data (operation data) from the internal database 23 and related data (customer information) attached to it, the web server reflects it on the website operated by itself.

  Therefore, in this device, for example, when a customer or a service person wants to know the dynamic data of the work machine 11 owned or in charge, he / she accesses the website of the management unit 15 from his / her terminal and instructs the data acquisition request. Can be put out.

  In response to this instruction, the web server of the management unit 15 transmits the command data in the XML data format to the management server of the internal database 23. Therefore, the management server sends the XML of the desired work machine from the internal database 23. While taking out the dynamic data in the data format, the related data is also taken out and sent back to the web server. In the web server, dynamic data and related data are added to the web site and reflected on the website. Thereby, a customer or a service person can acquire dynamic data together with related data. When a customer or a service person connects his / her own database to his / her terminal, the dynamic data acquired from the website is in the XML data format, and can be directly imported into the database.

  Data exchange between the work machine 11 and the management unit 15 is also performed in the XML data format, and the work machine side data acquisition means is caused to function as a service provider. The software rewriting system 42, the repair service system 44, the rental system 45, and the instruction acquisition intranet network 46 that exchange data with the web server of the data connection processing unit 22 in the XML data format are the same as the various information databases 43. To act as a service provider.

  As described above, the application on the management unit 15 side in the work machine remote operation management system 10 uses the XML data format as the data format for data exchange with the web server of the data connection processing unit 22, and at least the web server is a service requester. In addition, since each server connected to the web server is made to function by the service provider, the dynamic data and the related data returned from the service provider are also in the XML data format. In addition, it is easy for the customer side or an external system to capture the data as it is via a web server.

  In other words, it is compatible with the XML data format, which is a standard format in the construction industry, and this XML data format is also a universal data format that extends to the whole world. Can pass. Furthermore, depending on the mode, it is possible to connect to an external system and allow the web server of the data connection processing unit 22 to function as a service requester so that the dynamic data acquired by the web server is directly taken into the external system. Is possible.

  Further, it is easy to increase the number of servers as service providers connected to the website of the management unit 15, and in this case, it is possible to increase the processing of the management system itself. On the other hand, since it is sufficient for the web server of the data connection processing unit 22 to function as a service requester, the burden on the management unit itself does not increase, and the effect of upgrading the apparatus at a low cost can be obtained while the mechanism is simple.

  That is, for system construction, it is not necessary to create each system configuration including cooperation with other systems as in the past, and only one web service of the cooperation connector, that is, the data connection processing unit 22, is created. Various other systems such as a software rewriting system 42, various information databases 43, a repair business system 44, a rental system 45, an intranet network 46 for obtaining instructions, and their web services 42ws, 43ws, 44ws, 45ws , 46ws can be easily linked, so it is easy to connect with each original interface and can be created at low cost.

  Furthermore, it is easy to add or modify another system after the work machine remote operation management system 10 is completed. For example, a software rewriting system 42, various information databases 43, a repair business system 44, a rental system 45, and an instruction acquisition intranet. Even if other systems such as the network 46 are linked, it is not necessary to develop a system for putting these other systems in the work machine remote operation management system 10, and the web services 42ws, By simply attaching 43ws, 44ws, 45ws, 46ws, another system can be added.

  Next, FIG. 3 shows a dynamic management controller 26 which is a dynamic data management apparatus that controls data exchange inside and outside the work machine 11, and an airframe control controller 30 that controls various devices of the work machine 11. .

  The input / output signal processing unit 67 is connected to various devices 56 such as an engine controller, a pump controller, and sensors, and takes operation data obtained from the sensors into the dynamic management controller 26 as machine information. Output depending on the type of relay, etc., and depending on the model, it is possible to cope with the case where the machine control controller 30 is not installed.

  The power control unit 68 is connected to the arithmetic processing unit 61, the wireless communication unit 64, and the date management unit 66, and controls the on / off of these internal power sources.

  The storage of each data in the storage unit 62 is processed according to a command of the arithmetic processing unit 61, among which an operating time accumulator, a fuel remaining amount sensor, an engine speed provided in various devices 56 of the work machine 11 Predetermined operation data (operation information (operation time information, remaining fuel information), machine information, maintenance information, and warning information) obtained from sensors such as a sensor, a temperature sensor, and a pressure sensor is input / output signal processing unit 67. The data is stored in the operation data storage unit 71 of the storage unit 62 via the arithmetic processing unit 61.

  Of these operating data, if there is abnormal data that matches the conditions for issuing a warning, it is also stored in the spontaneous transmission data storage unit 72 as warning information. When warning information is stored in the spontaneous transmission data storage unit 72, as will be described later, the arithmetic processing unit 61 displays warning information on the management unit 15 side regardless of the presence or absence of a call e-mail from the management unit 15. Output a command to send.

  The control command of the arithmetic processing unit 61 is based on the setting data stored in the setting data storage unit 73 of the storage unit 62, but the setting data to be updated is transmitted from the management unit 15 side, which is the setting data It is stored in the storage unit 73.

  A notebook computer 77 can be connected to the in-vehicle electronic device network 51 via a service tool 76. The notebook computer 77 communicates with the movement management controller 26 and the machine body control controller 30 via the in-vehicle electronic device network 51 to display machine information and the like on the notebook computer 77 in real time.

  Next, communication processing in the behavior management controller 26 will be described.

  As long as the main power switch is turned on, the arithmetic processing unit 61 constantly checks whether the call e-mail from the management unit 15 is received and stored in the memory of the wireless communication unit 64. .

  When the calling e-mail is transmitted from the management unit 15, it is received by the radio communication unit 64 and immediately stored in the memory of the radio communication unit 64. When the checked arithmetic processing unit 61 confirms the storage, the wireless communication unit 64 retrieves the telephone number of the management unit 15 from the memory of the wireless communication unit 64 and makes the call to the management unit 15 side.

  When the wireless communication unit 64 communicates with the management unit 15, if there is setting data from the management unit 15, it is transmitted, and a transmission request for the desired work machine 11 is transmitted along with it. The arithmetic processing unit 61 first confirms whether or not the setting data has been received, and if received, saves it in the setting data storage unit 73 of the storage unit 62 and updates it, and the management unit 15 uses the updated result as data. Return to the side. As described above, the setting data is a control command of the arithmetic processing unit 61, and after the update, control is performed based on the updated setting.

  Next, when confirming the operation data request, the arithmetic processing unit 61 extracts the operation data of the desired work machine 11 from the operation data storage unit 71 and transmits the operation data from the wireless communication unit 64 to the management unit 15. The management unit 15 that has received the operation data reflects the operation data on the website and provides information to the customer or service person.

  Next, the arithmetic processing unit 61 confirms the presence or absence of warning information in the spontaneous transmission data storage unit 72 of the storage unit 62, and if there is warning information, extracts the data and transmits the data from the wireless communication unit 64 to the management unit 15. .

Upon receiving this data, the management unit 15 side temporarily stores it in its own database 23 and reflects it on its own website in a predetermined output format. As a result, the desired operation data at that time is displayed on the customer terminal device 17 or the in-house terminal device 19.

  In this data flow, the dynamic management controller 26 of the work machine 11 obtains power directly from the battery of the work machine 11 even when the engine key switch is off, and operates as long as the main power switch is not turned off. Even when the work machine 11 is not operating, it is in a posture to constantly monitor and respond to the e-mail for calling from the management unit 15 side, so unless the main power switch is turned off, the customer or in-house (dealer) Can request and obtain real-time operational data on the desired work machine 11 at any time through the website operated by the management unit 15.

  As for the warning information, if it is stored in the spontaneous transmission data storage unit 72, as long as the main power switch is on, the warning information is immediately transmitted from the work machine 11 side to the management unit 15 side, and the customer terminal device is transmitted by e-mail. 17 or in-house terminal device 19, it is possible to know in real time that the work machine 11 is abnormal.

  In particular, using the GPS position information acquired through the position measuring unit 65 of the movement management controller 26, the assumed region where the operating position of the work machine 11 is set in relation to the date and time managed by the date managing unit 66 is used. When the work machine 11 moves outside, if the position information is stored as warning information, the customer or serviceman can immediately determine whether or not it is stolen in a remote place. In addition, in the case of position information that can be assumed to be highly likely to be stolen, a start restriction function such as the aircraft controller 30 shutting off the engine start circuit by itself based on a warning signal from the dynamic management controller 26 is provided. By providing it, it is possible to prevent theft.

  In addition, all the operation data requests from the customer terminal device 17 or the in-house terminal device 19 are routed through the management unit 15, so that the work machine 11 only sends the operation data to the management unit 15. Since the start of the data transmission is limited to the presence or absence of an e-mail for calling from the management unit 15, the work machine 11 has no need for the customer authentication mechanism for passing the data, and has been accessed. Instead of handing over data sometimes, the call is terminated by the call, and then the work machine 11 side and the management unit send data to the management unit 15 to which the connection destination is set from the work machine 11 side. Both 15 have a simple system configuration and there is no risk of data leakage.

  That is, in this work machine remote operation management system 10, the destination of the dynamic data from the work machine 11 side is only the management unit 15 to which contact information is set in advance, and the customer terminal device through the website from the management unit 15 Since the data is provided to the terminal device 19 or the in-house terminal device 19, if the dynamic data is provided only to the management unit 15 on the work machine 11 side, the data can be provided to a plurality of customers or service personnel.

  This is because the work machine 11 can be accessed directly from a plurality of customer terminal devices 17 or in-house terminal devices 19 and the system can be simplified as compared with a system that provides data to the work machine 11 because no individual authentication mechanism is required. At the same time, the communication run cost can be kept low. In addition, data exchange with the work machine 11 is limited to the management unit 15 for which contact information is determined in advance, and since data flows through a limited line, the risk of information leakage is greatly reduced, and security is improved. The construction cost required for this is extremely low.

  In addition, since the management unit 15 performs batch exchange of data with the work machine 11 and reflects the received data on the website and provides it to the customer or service person, for example, only the numerical data from the work machine 11 Even if it is only received, at the stage of reflecting it on the website, raw data of only numerical values can be processed and displayed in the format desired by the customer or service person, and the system is suitable for the convenience of the customer or service person ing.

  In other words, when the management unit 15 performs the data exchange in a batch, the management unit 15 can sort out the operation data of the work machine 11 that is necessary for maintenance management and that required by the customer. Only necessary data can be provided for each of the customer and the service person. Furthermore, it is possible for the management unit 15 side to collect the operation data of all work machines at a fixed time and reflect the data on the website. Can be cheap.

  Next, with reference to the flowchart shown in FIG. 4, a flow for performing a refueling service from the remaining fuel information will be described.

(Step S1)
The management unit 15 acquires basic information such as vehicle information (unit information) and fuel remaining amount information from the work machine 11.

(Step S2)
Basic information such as vehicle information (unit information) and rental customer information is acquired from the rental system 45.

(Step S3)
The server in the management unit 15 constituting the work machine remote operation management system 10 includes vehicle information and remaining fuel information obtained from the work machine 11, vehicle information (car information) obtained from the rental system 45, and a rental destination. A list representing the relationship among the vehicle information, the remaining fuel amount information, and the rental destination customer information is automatically created from the customer information.

(Step S4)
The service person checks the above list and proposes fuel supply to the customer. This proposal is sent by e-mail from the mail distribution unit 24 to the customer personal computer 17pc or the customer mobile phone 17ph. This proposal may be made directly to the customer by telephone or facsimile.

(Step S5)
It is determined whether or not the customer information processing unit 35 has received (ordered) a request for refueling service from the customer personal computer 17pc.

(Step S6)
When receiving an order for a refueling service, the driver who drives a refueling vehicle such as a tank truck by using the map information database 41 receives the position information of the position measuring unit 65 that has received the radio wave from the GPS satellite 12 to determine the current position of the work machine 11 Output to the in-house mobile phone 19ph, identify the construction site where the work machine 11 of the corresponding unit is located, and arrange for refueling.

(Step S7)
The work machine 11 is refueled from the fuel tank.

(Step S8)
An electronic invoice corresponding to the amount of refueling is issued to the customer through accounting processing at the rental system 45 from the in-house personal computer 19pc.

(Step S9)
The customer pays through an internet bank or the like.

  Next, the effect of this system will be described.

  A rental system 45 outside the work machine remote operation management system is connected to the web service 22ws of the data connection processing unit 22 of the central work machine remote operation management system 10, and a web service 45ws of the same data format coupled to the rental system 45. By connecting through the system, it is possible to easily configure a system that uses the internal information of the rental system 45 to create a list that represents the relationship between the vehicle information, the remaining fuel amount information, and the rental customer information. You can easily maintain and update the list creation system. Furthermore, the work machine remote operation management system 10 has only the management unit 15 as the transmission destination of vehicle information and fuel remaining amount information from the work machine 11 side, and the management unit 15 transmits the information to the terminal devices 17 and 19 through the website. Since these pieces of information are provided, the authentication mechanism between the work machine 11 and each of the terminal devices 17 and 19 is compared with a system in which the work machine is directly accessed from a plurality of terminal devices to provide the information. The system can be simplified as much as it becomes unnecessary, and data exchange with the work machine 11 is limited to the management unit 15 for which contact information is determined in advance, such as vehicle information and fuel remaining amount information on a limited line Therefore, the risk of leakage of this information is greatly reduced, and the construction cost required for security can be reduced.

  Since the location information of the work machine 11 transmitted from the work machine 11 to the management unit 15 by wireless communication is reflected on the website and provided to the terminal device 19, it is possible to easily perform the work of identifying the refueling delivery site and arranging the refueling.

  In this way, refueling arrangements can be carried out smoothly, reducing downtime due to fuel shortage, improving productivity due to this reduction, reducing labor and repair costs due to service arrangements due to lack of fuel, working machine operators and It can prevent troublesomeness of the fuel remaining amount check by the administrator.

  The present invention can be applied to a hydraulic excavator, a bulldozer, a loader, or the like equipped with a work machine remote operation management system that manages operation of a work machine in a remote place.
