  Hereinafter, an embodiment for carrying out this case will be described with reference to the drawings.

  FIG. 1 shows an example of the work support system S. The work support system S includes a portable terminal 100 and a server device 200 as a work support device. Examples of the portable terminal 100 include a smart device such as a smartphone and a wearable device such as a smart watch. The mobile terminal 100 is attached to, for example, the arms and wrists of workers M1 and M2 who work in the work facility X. Attachment to an arm part or a wrist is performed through a belt or a wristband, for example. The portable terminal 100 displays a work manual as a work instruction to the workers M1 and M2. Workers M1 and M2 confirm the instructions displayed on the mobile terminal 100 and perform operations for assembling various devices, or operate the operation target devices X1 and X2 such as a cutting machine to process parts. To do.

  When the workers M1 and M2 finish the work, they operate the mobile terminal 100 to input the completion of the work. For example, when the workers M1 and M2 advance the work manual, completion of the work is input to the portable terminal 100. In addition, the workers M1 and M2 operate the portable terminal 100 and input the start of work before starting various kinds of work. Further, the workers M1 and M2 operate the mobile terminal 100 and input the work interruption before interrupting various kinds of work. In addition, the workers M1 and M2 input various instructions, and details of the input contents will be described later. When the mobile terminal 100 detects information such as completion of work, start of work, or interruption of work, the mobile terminal 100 transmits the information to the server device 200. The information transmitted from the portable terminal 100 reaches the server device 200 via the access point AP and the communication network NW. The communication network NW includes a local area network (LAN) and the Internet.

  On the other hand, the server device 200 accepts input of environmental values and environmental sounds detected by the environmental sensors Y1, Y2, and Y3 installed in the work facility X. Examples of the environmental sensors Y1, Y2, and Y3 include a temperature sensor, an illuminance sensor, and a microphone. In addition, the server device 200 receives input of information related to an abnormality in the operation target devices X1 and X2. Information regarding the input of environmental values and environmental sounds and abnormalities reach the server device 200 via the communication network NW. When the server apparatus 200 accepts these inputs, the server apparatus 200 holds the information together with the information transmitted from the mobile terminal 100. When the information related to the resumption of work is transmitted from the mobile terminal 100, the server apparatus 200 can confirm the state before the work is interrupted. A digest page is generated and transmitted to the mobile terminal 100. The mobile terminal 100 displays the digest page generated by the server device 200. Thereby, for example, the worker M1 can accurately confirm the situation before the work is interrupted.

Good. The CPU 200A to the drive device 200I are connected to each other by an internal bus 200J. At least the CPU 200A and the RAM 200B cooperate to realize a computer.

An input device 710 is connected to the input I / F 200F. Examples of the input device 710 include a keyboard and a mouse.
A display device 720 is connected to the output I / F 200G. An example of the display device 720 is a liquid crystal display.

When the stored program is executed by the CPU 200A, various functions to be described later are realized, and various processes to be described later are executed. In addition, what is necessary is just to make a program according to the flowchart mentioned later.

  Next, functions of the mobile terminal 100 will be described with reference to FIGS. 4 to 6.

  FIG. 4 is an example of a functional block diagram of the mobile terminal 100. FIG. 5 shows an example of the peripheral event storage condition. FIG. 6 is an example of a peripheral event record. First, as illustrated in FIG. 4, the mobile terminal 100 includes a work manual display unit 101 and a work progress management unit 102. The mobile terminal 100 also includes a storage condition first storage unit 103, a peripheral event storage unit 104, and a peripheral event storage unit 105. Furthermore, the portable terminal 100 includes a peripheral event writing unit 106, a digest display unit 107, and an interrupt event receiving unit 108. In FIG. 4, hardware components are shown in parentheses.

  The work manual display unit 101 displays a work manual on the display 100I based on an instruction input from the touch panel 100H. The work manual includes, for example, symbols representing work contents and precautions during work. For example, when the fact that the work of the work manual is completed is input from the touch panel 100H, the work progress management unit 102 outputs information indicating the completion of the work to the server device 200 via the RF circuit 100E. The same applies to the case where the work is started or the work is stopped.

  The storage condition first storage unit 103 stores a storage condition for the peripheral event storage unit 104 to store a peripheral event described later in the peripheral event storage unit 105. Specifically, as shown in FIG. 5, the storage condition first storage unit 103 manages the storage conditions using the peripheral event storage condition table. The peripheral event storage condition table includes a type, a storage condition, and a message as components. The type represents a device that has detected a peripheral event. For example, the type “microphone” indicates that the microphone 100J has detected a peripheral event. For example, the type “GPS” indicates that the sensor 100F (specifically, a GPS sensor) has detected a surrounding event. For example, the type “barcode” indicates that the camera 100G (specifically, a barcode reader) has detected a peripheral event. The storage condition represents a condition in which the peripheral event storage unit 104 stores the peripheral event in the peripheral event storage unit 105. The message represents the contents of the surrounding event.

  Here, the peripheral events described above are around the mobile terminal 100, such as an event that has occurred in relation to the behavior or state (for example, health condition) of the worker who performs the work, or an event that has occurred in relation to a change in the work tool used in the work. It is an event that occurred. For example, when the worker M1 takes an action deviating from his / her work place, the sensor 100F detects the action as a surrounding event. For example, when the worker M1 coughs frequently, the microphone 100J detects the sound as a surrounding event. For example, when a barcode attached to another work tool is read by the camera 100G in order to change the work tool used by the worker M1, the camera 100G detects a change in the work tool as a peripheral event.

  The peripheral event storage unit 104 receives the position and movement of the mobile terminal 100 detected by the sensor 100F, the image (specifically, a two-dimensional barcode) captured by the camera 100G, and the sound collected by the microphone 100J as peripheral events. When the peripheral event storage unit 104 receives the peripheral event, the peripheral event storage unit 104 reads the storage condition from the storage condition first storage unit 103 and specifies the peripheral event to be stored in the peripheral event storage unit 105. When the peripheral event storage unit 104 specifies a peripheral event that satisfies the storage condition, the peripheral event storage unit 104 stores the specified peripheral event in the peripheral event storage unit 105 as a peripheral event record. That is, storage of peripheral events that do not satisfy the storage condition in the peripheral event storage unit 105 is excluded. Thereby, the peripheral event storage unit 105 stores a specific peripheral event record.

  Specifically, as shown in FIG. 6, the peripheral event storage unit 105 manages various peripheral event records using the peripheral event table. The peripheral event table includes worker code, order ID, type, date of occurrence, time of occurrence, message, and image data as components. The worker code is identification information for identifying the worker. The order ID is identification information for identifying an order representing a work instruction obtained by disassembling a process for completing one product or apparatus into a process and a work. Occurrence date and occurrence time are the date and time when the surrounding event occurred, respectively. The image data is binary data representing a screen shot of a screen displayed on the mobile terminal 100 (more specifically, a portion indicating the work content in the screen). Since the type and message have already been described, details are omitted.

  The peripheral event writing unit 106 generates a thumbnail image of the above-described screen shot based on the interruption instruction input from the touch panel 100H, and writes the generated thumbnail image to the server device 200 via the RF circuit 100E. In addition, the peripheral event writing unit 106 acquires a peripheral event record from the peripheral event storage unit 105 based on the instruction, and writes the peripheral event record to the server device 200 via the RF circuit 100E.

  The digest display unit 107 displays the above-described digest page on the display 100I based on an instruction for requesting resumption of work input from the touch panel 100H. More specifically, when the digest display unit 107 detects an instruction to request resumption of work, the digest display unit 107 requests the server device 200 to generate a digest page via the RF circuit 100E. The digest display unit 107 receives and displays the digest page generated by the server device 200 via the RF circuit 100E.

  The interruption event reception unit 108 receives an interruption event record (to be described later) transmitted from the server device 200 based on an instruction to confirm the resumption of work input from the touch panel 100H, and stores it in the peripheral event storage unit 105. More specifically, when the interruption event reception unit 108 detects an instruction to confirm the resumption of work, the interruption event reception unit 108 notifies the server apparatus 200 of the confirmation of work resumption. Based on the notification, the server apparatus 200 transmits an interruption event record stored by itself to the interruption event reception unit 108. As a result, the interrupt event receiving unit 108 receives the interrupt event record transmitted from the server device 200 and stores it in the peripheral event storage unit 105.

  Next, functions of the server device 200 will be described with reference to FIGS.

  FIG. 7 is an example of a functional block diagram of the server device 200. FIG. 8 is an example of a work history table. FIG. 9 shows an example of common event storage conditions. FIG. 10 is an example of a common event record. FIG. 11 is an example of an interruption event record. As illustrated in FIG. 7, the server device 200 includes a work history storage unit 201, a storage condition second storage unit 202, a common event storage unit 203 as a processing unit, and a common event storage unit 204. In addition, the server device 200 includes a peripheral worker identification unit 205, an interruption event storage unit 206, a digest generation unit 207 as a processing unit, and an interruption event transmission unit 208. In FIG. 7, hardware components are shown in parentheses.

  The work history storage unit 201 stores a work history record representing a history of work performed by the worker M1 or the worker M2. Specifically, as shown in FIG. 8, the work history storage unit 201 manages work history records using a work history table. The work history table includes an order ID, process number, process name, work number, work content, work place code, person in charge code, person in charge, terminal ID, start time, end time, and status as components. The process number and the process name are a number for identifying the process and a process name, respectively. The work number and the work content are a number for identifying the work and a work name, respectively. The work place code is a number for identifying the work place in the work facility X. The person-in-charge code and the person-in-charge are identification information for identifying the person in charge as an order destination and the name of the person in charge. The terminal ID is identification information of the portable terminal 100 that was carried when the worker performed the work. The start time, the end time, and the state are the time when the work is started, the time when the work is finished, and the state of the work, respectively. In this way, the work history storage unit 201 manages the work progress of the person in charge for each order ID.

  The storage condition second storage unit 202 stores a storage condition for the common event storage unit 203 to store a common event described later in the common event storage unit 204. Specifically, as shown in FIG. 9, the storage condition second storage unit 202 manages the storage conditions using a common event storage condition table. The common event storage condition table includes a type, a storage condition, and a message as components. The type represents a device that has detected a common event. For example, the type “room temperature” indicates that the environmental sensor Y1 (specifically, the temperature sensor) has detected a common event. For example, the type “noise” indicates that the environmental sensor Y3 (specifically, a microphone) has detected a common event. For example, the type “device” indicates that the operation target devices X1 and X2 have detected a common event. The storage condition represents a condition that the common event storage unit 203 stores in the common event storage unit 204. The message represents the contents of the common event.

  Here, the above-described common event includes events that occurred in the operation target devices X1 and X2 and measurement devices (not shown) used by the worker, events such as a work plan change, and a work facility where the worker performs the work. This is an event that occurs regardless of the periphery of the mobile terminal 100, such as an event related to the environment of X. For example, when the room temperature of the work facility X becomes high, the environment sensor Y1 detects the high room temperature as a common event. For example, when the work facility X becomes a power failure, the environment sensor Y2 (specifically, the illuminance sensor) detects the power failure as a common event. For example, when noise occurs in the work facility X, the environmental sensor Y3 (specifically, a microphone) detects the noise as a common event. For example, when an abnormality occurs in the operation target device X1 used by the worker M1 in the work, the operation target device X1 detects its own abnormality as a common event.

  The common event storage unit 203 accepts common events detected by the environmental sensors Y1, Y2, and Y3 and common events detected by the operation target devices X1 and X2. When receiving the common event, the common event storage unit 203 reads the storage condition from the storage condition second storage unit 202 and specifies the event to be stored in the common event storage unit 204. When the common event storage unit 203 identifies a common event that satisfies the storage condition, the common event storage unit 203 stores the identified common event in the common event storage unit 204 as a common event record. That is, the storage of the common event that does not satisfy the storage condition in the common event storage unit 204 is excluded. Thereby, the common event storage unit 204 stores a specific common event record.

  Specifically, as shown in FIG. 10, the common event storage unit 204 manages various common event records using a common event table. The common event table includes a location code, an order ID, a type, an occurrence date, an occurrence time, and a message as components. The location code is a coordinate code for specifying an influence range of an object (specifically, room temperature, noise, abnormality of the operation target devices X1 and X2, etc.). The order ID is identification information for specifying an influence range of a target (specifically, room temperature, noise, abnormality of operation target devices X1 and X2, etc.). The details of the type, the date of occurrence, the time of occurrence, and the message have already been described and will be omitted. A wild card “*” can be used for the place code and the order ID.

  When the peripheral worker identification unit 205 is requested by the portable terminal 100 to identify the peripheral worker via the communication circuit 200D, the worker (for example, the worker who interrupted the work) based on the work history record stored in the work history storage unit 201 ( For example, another worker (for example, worker M2) who works around worker M1) is specified as the surrounding worker. More specifically, the peripheral worker specifying unit 205 inquires about the position of the portable terminal 100 carried by another worker based on the work history record, and the portable terminal 100 carried by the worker who suspended the work and the position of the inquiry result. The surrounding workers are specified by calculating the distance of the position. When the peripheral worker specifying unit 205 specifies the peripheral worker, the interrupt event storage unit 206 stores an interrupt event record including the type “memory”.

  The interruption event storage unit 206 stores various interruption event records. Specifically, as shown in FIG. 11, the interruption event storage unit 206 manages various interruption event records using an interruption event table. The interruption event table includes a worker code, an order ID, a type, an occurrence date, an occurrence time, a message, and image data as components. As described above, the interruption event storage unit 206 interrupts the type “memories image” related to the thumbnail image written from the mobile terminal 100 in addition to the interruption event record of the type “memories” stored by the peripheral worker identification unit 205. Store event records. The interruption event storage unit 206 stores various peripheral event records written from the portable terminal 100 as interruption event records. The interruption event storage unit 206 stores the thumbnail image as binary data.

  When a digest page is requested from the portable terminal 100, the digest generation unit 207 acquires a work history record, a common event record, and an interruption event record from the work history storage unit 201, the common event storage unit 204, and the interruption event storage unit 206, respectively. . The digest generation unit 207 generates a digest page based on the acquired work history record, common event record, and interruption event record, and transmits the generated digest page to the mobile terminal 100 via the communication circuit 200D.

  When the interruption event transmission unit 208 is notified of the resumption confirmation from the portable terminal 100, the interruption event transmission unit 208 acquires a specific interruption event record from the interruption event storage unit 206, and transmits the specific interruption event record to the portable terminal 100 via the communication circuit 200D.

  Next, the operation of the work support system S will be described.

  First, with reference to FIG. 12, an operation for accumulating the peripheral event records in the peripheral event storage unit 105 of the mobile terminal 100 will be described.

  FIG. 12 is a flowchart showing an example of the operation of the peripheral event storage unit 104. First, the peripheral event storage unit 104 waits until a peripheral event is received (step S101: NO). When the peripheral event storage unit 104 receives the peripheral event (step S101: YES), the peripheral event storage unit 104 reads the storage condition of the peripheral event (see FIG. 5) from the storage condition first storage unit 103 (step S102). When the process of step S102 is completed, the peripheral event storage unit 104 then determines whether the peripheral event satisfies the storage condition (step S103). When the storage condition is satisfied (step S103: YES), the peripheral event storage unit 104 stores the peripheral event that satisfies the storage condition in the peripheral event storage unit 105 as a peripheral event record (step S104). Conversely, when the storage condition is not satisfied (step S103: NO), the peripheral event storage unit 104 skips the process of step S104. As a result, a specific peripheral event record is accumulated in the peripheral event storage unit 105 (see FIG. 6).

  Next, with reference to FIG. 13, an operation for accumulating a common event record in the common event storage unit 204 of the server apparatus 200 will be described.

  FIG. 13 is a flowchart showing an example of the operation of the common event storage unit 203. First, the common event storage unit 203 waits until a common event is received (step S201: NO). When the common event storage unit 203 receives the common event (step S201: YES), the common event storage unit 203 reads the common event storage condition (see FIG. 9) from the storage condition second storage unit 202 (step S202). When the process of step S202 is completed, the common event storage unit 203 then determines whether the common event satisfies the storage condition (step S203). If the storage condition is satisfied (step S203: YES), the common event storage unit 203 stores the common event that satisfies the storage condition in the common event storage unit 204 as a common event record (step S204). Conversely, if the storage condition is not satisfied (step S203: NO), the common event storage unit 203 skips the process of step S204. As a result, a specific common event record is accumulated in the common event storage unit 204 (see FIG. 10).

  Next, with reference to FIG. 14 to FIG. 17, the operation of the mobile terminal 100 when the work is interrupted will be described.

  FIG. 14 is a flowchart showing an example of the operation of the peripheral event writing unit 106. FIG. 15 shows a screen example (part 1) when the work is interrupted. FIG. 16 shows a screen example (part 2) when the work is interrupted. FIG. 17 shows a screen example (part 3) when the work is interrupted.

  First, as shown in FIG. 14, the peripheral event writing unit 106 waits until an interruption instruction is accepted (step S301: NO). When the peripheral event writing unit 106 receives the interruption instruction (step S301: YES), the peripheral event writing unit 106 acquires a screen shot of the screen when the interruption instruction is received (step S302). More specifically, as shown in FIG. 15, for example, when the worker M1 presses the work interruption button BT1 included in the work manual displayed on the portable terminal 100 with his / her finger FG, the peripheral event writing unit 106 issues an interruption instruction. Accept. Then, when the peripheral event writing unit 106 receives the interruption instruction, the peripheral event writing unit 106 acquires a screen shot of the screen portion 10 including the design representing the work content and the precautions during the work. In FIG. 15, when the previous page button BT2 is pressed, the work manual display unit 101 displays the work manual immediately preceding the displayed work manual. On the other hand, when the next page button BT3 is pressed, the work manual display unit 101 displays a work manual immediately after the displayed work manual.

  When the process in step S302 is completed, the peripheral event writing unit 106 then generates a thumbnail image of the acquired screen shot (step S303), and writes the thumbnail image in the interrupt event storage unit 206 of the server device 200 (step S304). . More specifically, the peripheral event writing unit 106 associates the worker code, the order ID, and the type “memory image” with the thumbnail image, and writes them in the interrupt event storage unit 206 as an interrupt event record. For example, the date and time when the interruption instruction is received are registered in the occurrence date and the occurrence time. Thereby, the interruption event storage unit 206 stores the interruption event record of the type “memory image” (see FIG. 11).

  When the process of step S304 is completed, the peripheral event writing unit 106 then accesses the peripheral event table of the peripheral event storage unit 105 (step S305). Then, the peripheral event writing unit 106 determines whether there is a peripheral event record (step S306). When there is a peripheral event record (step S306: YES), the specific peripheral event record is written in the interrupt event storage unit 206 of the server device 200 (step S307). More specifically, the peripheral event writing unit 106 writes the peripheral event record other than the peripheral event record including the type “memory” from the peripheral event storage unit 105 to the interruption event storage unit 206. By excluding the writing of the peripheral event record including the type “memory” to the interrupt event storage unit 206, the interrupt event storage unit 206 stores the latest peripheral event record including the type “memory” as the interrupt event record. Then, the interruption event transmission unit 208 of the server device 200 transmits this interruption event record, and the interruption event reception unit 108 of the mobile terminal 100 receives and stores it in the peripheral event storage unit 105. Thereby, even if there are a plurality of interruption instructions, the worker M1 can remember the situation at the time of interruption by the latest peripheral event record including the type “memory”.

  When the process of step S307 is completed, the peripheral event writing unit 106 then clears the peripheral event storage unit 105 (step S308), and requests the peripheral worker specifying unit 205 of the server device 200 to specify the peripheral worker ( Step S309). More specifically, the surrounding event writing unit 106 requests the identification of the surrounding worker along with the transmission of the worker code, the order ID, and the position of the mobile terminal 100. Thereby, the surrounding worker specifying unit 205 starts specifying the surrounding worker.

  If there is no peripheral event record in the process of step S306 (step S306: NO), the peripheral event writing unit 106 skips the processes of steps S307 and S308 and executes the process of step S309.

  In addition, in the processing of step S301 described above, when the peripheral event writing unit 106 receives an interruption instruction, the work manual display unit 101 is parallel to the processing from step S302 to S309 or after the processing of step S309. A predetermined screen is displayed on the display 100I. More specifically, when the work interruption button BT1 is pressed, as shown in FIG. 16, the work manual display unit 101 displays a screen for confirming the interruption of the work. When the OK button BT4 is pressed, as shown in FIG. 17, the work manual display unit 101 displays a screen that indicates that the operation has been suspended. Thereby, the worker can interrupt the work and enter a break (for example, a toilet break or lunch).

  Next, with reference to FIG. 18, the operation of the server apparatus 200 at the time of work interruption will be described.

  FIG. 18 is a flowchart showing an example of the operation of the peripheral worker specifying unit 205. As shown in FIG. 18, the peripheral worker specifying unit 205 waits until the peripheral event writing unit 106 requests the specification of the peripheral worker (step S401: NO). As described above, when the peripheral event writing unit 106 requests the peripheral worker specifying unit 205 to specify the peripheral worker (step S401: YES), the peripheral worker specifying unit 205 extracts a specific work history record α (step S402). . More specifically, the peripheral worker specifying unit 205 accesses the work history storage unit 201, and is a person-in-charge code that does not correspond to the worker code transmitted from the peripheral event writing unit 106, and the state is being worked on. A certain work history record is extracted as a work history record α. During the work, the start time is registered, but the end time is not registered. As a result, the peripheral worker specifying unit 205 obtains the work history record α of another worker (for example, the worker M2) other than the worker (for example, the worker M1) who interrupted the work and who is working. Extract.

  When the process of step S402 is completed, the surrounding worker specifying unit 205 then determines whether or not the work history record α exists (step S403). When the peripheral worker specifying unit 205 has extracted the work history record α and determines that the work history record α exists (step S403: YES), the peripheral worker specifying unit 205 determines the position of the mobile terminal 100 managed by the work history record α. An inquiry is made (step S404). That is, for example, when the worker M1 interrupts the work, the worker M1 inquires about the position of the portable terminal 100 carried by the worker (for example, the worker M2) having a person-in-charge code different from the worker code of the worker M1. Thereby, the surrounding worker specifying unit 205 obtains an inquiry result β representing the position of the mobile terminal 100 carried by a worker other than the worker M1.

  When the process of step S404 is completed, the neighboring worker specifying unit 205 then calculates the distance between the terminals from the position of the inquiry result β and the position of the mobile terminal 100 that interrupted the work (step S405). That is, the peripheral worker specifying unit 205 calculates the distance between the terminals from the position of the inquiry result β and the position of the portable terminal 100 transmitted from the peripheral event writing unit 106. When there are a plurality of positions of the inquiry result β, the surrounding worker specifying unit 205 calculates the distance between the terminals.

  When the process of step S405 is completed, the surrounding worker specifying unit 205 determines whether or not the portable terminal 100 is in the vicinity (step S406). For example, based on the calculated distance and a predetermined threshold, the surrounding worker specifying unit 205 determines whether there is a portable terminal 100 of another worker (for example, worker M2) in the vicinity of the portable terminal 100 of the worker M1. Judge whether or not.

  When there is the mobile terminal 100 in the vicinity (step S406: YES), the surrounding worker identification unit 205 stores the interruption event record of the type “memory” in the interruption event storage unit 206 (step S407). More specifically, the peripheral worker specifying unit 205 sets the worker code and order ID transmitted from the peripheral event writing unit 106 to the person-in-charge code and order ID, respectively, and interrupts the top three in the order of short distance. Stores event records. At this time, the peripheral worker specifying unit 205 registers a predetermined message such as “'worker name” was working on “work contents” in the vicinity ”in the interruption event record to be stored. As a result, for example, as shown in FIG. 11, the interruption event storage unit 206 stores an interruption event record including a message such as “Jiro Sato was working on“ part assembly ”in the vicinity”. In FIG. 11, interruption event records other than the type “memory” are written to the interruption event storage unit 206 by the peripheral event writing unit 106.

  Next, with reference to FIG. 19 to FIG. 21, the operation of the mobile terminal 100 when the work is resumed will be described.

  FIG. 19 is a flowchart showing an example of the operation of the digest display unit 107. FIG. 20 shows an example of a screen when resuming work. FIG. 21 is an example of a digest page.

  First, as shown in FIG. 19, the digest display unit 107 stands by until a restart instruction is accepted (step S501: NO). When the digest display unit 107 receives a restart instruction (step S501: YES), the digest display unit 107 requests a digest page from the digest generation unit 207 of the server device 200 together with the transmission of the order ID (step S502). For example, when the worker M1 who has suspended the work resumes the work, the portable terminal 100 is instructed to resume the work. When the work manual display unit 101 of the portable terminal 100 is instructed to resume work, the work manual display unit 101 displays a screen for specifying an order when the work is resumed, as shown in FIG. When worker M1 specifies an order ID for resuming work and presses resumption request button BT6, digest display unit 107 accepts a resumption instruction. As a result, the digest display unit 107 requests a digest page.

  When the process of step S502 is completed, the digest display unit 107 then receives the digest page transmitted from the digest generation unit 207 (step S503). As will be described in detail later, when a digest page is requested from the digest display unit 107, the digest generation unit 207 generates a digest page and transmits it to the digest display unit 107. As a result, the digest display unit 107 receives the digest page.

  When the process of step S503 is completed, the digest display unit 107 displays the received digest page (step S504). As a result, a digest page appears on the mobile terminal 100 as shown in FIG.

  The digest page includes various information that can confirm the status before the work is interrupted in addition to the work history. For example, when the worker M1 is performing the cutting operation, the digest page indicates that there are frequent coughs, the inside of the work facility X has become a high room temperature, the worker M1 has deviated from the work place, and the like. included. In addition, when the worker M1 interrupts the part assembly work, another worker in the vicinity of the worker M1 is Jiro Sato who was being assembled nearby, and the work manual displayed at the time of the suspension A thumbnail image D is included in the digest page. Thereby, when the worker M1 resumes the work, the situation at the time of interruption can be grasped, and even when the worker M2 performs the remaining work on behalf of the worker M1, the situation at the time of interruption is grasped. be able to.

  Next, with reference to FIG. 22, the operation of the server apparatus 200 when the work is resumed will be described.

  FIG. 22 is a flowchart showing an example of the operation of the digest generation unit 207. As shown in FIG. 22, the digest generation unit 207 waits until a digest page is requested (step S601: NO). When a digest page is requested (step S601: YES), the digest generation unit 207 extracts a specific work history list A corresponding to the order ID (step S602). More specifically, the digest generation unit 207 searches the work history table using the order ID as a key, and extracts a plurality of work history records whose status is complete or suspended. Further, the digest generation unit 207 extracts a work history list A including a process name, work content, start time, and end time from the extracted work history record.

  When the process of step S602 is completed, the digest generation unit 207 then extracts a work place code and a start time corresponding to the order ID from the work history table (step S603). When the processing in step S603 is completed, the digest generation unit 207 then acquires a specific interruption event list B corresponding to the order ID from the interruption event table (step S604). More specifically, the digest generation unit 207 acquires a specific interruption event record corresponding to the order ID as an interruption event list B.

  When the process of step S604 is completed, the digest generation unit 207 then acquires a common event list C corresponding to the order ID, work place code, and start time from the common event storage unit 204 (step S605). More specifically, the digest generation unit 207 has the generation time after the start time extracted in the process of step S603, the place code is the work place code extracted in the process of step S603, and the order ID is the portable terminal 100. The common event record that matches the order ID transmitted from the digest display unit 107 is acquired as the common event list C. If a wild card is set for the location code and order ID of the common event record, the digest generation unit 207 determines that the search condition is met.

  When the process of step S605 is completed, the digest generation unit 207 then merges the work history list A, the interrupt event list B, and the common event list C to generate a digest page (step S606). More specifically, the digest generation unit 207 merges the work history list A, the interrupt event list B, and the common event list C, and generates a digest page from the list α that is sorted in order of event occurrence time.

  When the process of step S606 is completed, the digest generation unit 207 then acquires the thumbnail image D corresponding to the order ID from the interruption event table (step S607), and adds the thumbnail image D to the end of the digest page (step S608). . When the process of step S608 is completed, the digest generation unit 207 transmits a digest page (step S609). As a result, the digest display unit 107 receives and displays the digest page (see FIG. 21).

  Next, with reference to FIG. 23 and FIG. 24, an operation of the mobile terminal 100 when resumption is confirmed will be described.

  FIG. 23 is a flowchart showing an example of the operation of the interrupt event receiving unit 108. FIG. 24 shows an example of a screen after resumption is confirmed. First, as shown in FIG. 23, the interrupt event receiving unit 108 waits until a resumption confirmation instruction is accepted (step S701: NO). When the interruption event reception unit 108 receives the resumption confirmation instruction (step S701: YES), the peripheral event storage unit 105 is cleared (step S702). For example, when the worker M1 confirming the digest page (see FIG. 21) presses the restart confirmation button BT7, the interrupt event receiving unit 108 receives a restart confirmation instruction. As a result, the interrupt event receiving unit 108 clears the peripheral event storage unit 105.

  When the process of step S702 is completed, the interruption event reception unit 108 then notifies the interruption event transmission unit 208 of the server device 200 of the resumption confirmation including the order ID (step S703). When the process of step S703 is completed, the interruption event reception unit 108 then receives the interruption event record transmitted from the interruption event transmission unit 208 (step S704). Although details will be described later, the interruption event transmission unit 208 transmits an interruption event record to the interruption event reception unit 108 when the interruption event reception unit 108 is notified of resumption. As a result, the interruption event reception unit 108 receives an interruption event record.

  When the process of step S704 is completed, the interruption event reception unit 108 then stores the received interruption event record in the peripheral event storage unit 105 (step S705). In the process of step S701 described above, when the interrupt event receiving unit 108 receives a resumption confirmation instruction, the work manual display unit 101 is parallel to the process from step S702 to S705 or after the process of step S705. A screen showing a work manual at the time of work interruption is displayed on the display 100I. More specifically, when the restart confirmation button BT7 (see FIG. 21) is pressed, as shown in FIG. 24, the work manual display unit 101 displays a screen showing the work manual when the work is interrupted. Thereby, the worker can resume the work.

  Next, with reference to FIG. 25, the operation of the server apparatus 200 when resuming is determined will be described.

  FIG. 25 is a flowchart showing an example of the operation of the interruption event transmission unit 208. As shown in FIG. 25, the interrupt event transmission unit 208 waits until notification of resumption is notified (step S801: NO). When the interruption event transmission unit 208 is notified of resumption (step S801: YES), the interruption event transmission unit 208 acquires an interruption event record corresponding to the order ID from the interruption event storage unit 206 (step S802).

  When the process of step S802 is completed, the interrupt event transmission unit 208 then determines whether there is an interrupt event record (step S803). If the interruption event transmission unit 208 has acquired the interruption event record and determines that there is an interruption event record (step S803: YES), the interruption event transmission unit 208 transmits the interruption event record (step S804). When the process of step S804 is completed, the interruption event transmission unit 208 clears the interruption event record corresponding to the order ID (step S805). Thereby, the interruption event receiving unit 108 can receive the interruption event record. On the other hand, if the interruption event transmission unit 208 cannot acquire the interruption event record and determines that there is no interruption event record (step S803: NO), the interruption event transmission unit 208 skips the processes of steps S804 and S805.

  As described above, according to the present embodiment, the mobile terminal 100 includes the peripheral event storage unit 104, and the server device 200 includes the common event storage unit 203. When the peripheral event storage unit 104 and the common event storage unit 203 accept a peripheral event or a common event that is not managed by the work history storage unit 201, the peripheral event storage unit associates the peripheral event or the common event with their occurrence time. 105 and the common event storage unit 204 respectively. The peripheral event stored in the peripheral event storage unit 105 is written in the interrupt event storage unit 206 as an interrupt event by the peripheral event writing unit 106.

  Further, the server device 200 includes a digest generation unit 207. When the digest generation unit 207 detects information for resuming work after detecting information for suspending work, the digest generation unit 207 refers to the work history storage unit 201, the common event storage unit 204, and the suspend event storage unit 206, and resumes the work. A digest page is generated that displays, in chronological order, common events and interruption events that occurred before detecting information, and work history up to the time when information that interrupts work is detected. The digest generation unit 207 transmits the generated digest page to the digest display unit 107, and the digest display unit 107 displays the digest page. As described above, the digest generation unit 207 may indirectly display the digest page, but for example, the digest generation unit 207 may directly display the digest page on the mobile terminal 100. Thereby, the worker can confirm the situation before the work interruption when the work is resumed.

  The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the specific embodiments according to the present invention, and various modifications are possible within the scope of the gist of the present invention described in the claims.・ Change is possible. For example, the digest display unit 107 displays peripheral events and common events within a predetermined time range (for example, from 10 am to 5 pm) or within a work range expressed as a predetermined number of work units (for example, from part assembly to device assembly). May be displayed.
