If an alert is detected during operation, the equipment MN outputs an alert to the operation display device DP as the equipment state of its own. When the processing of the work WK is completed and stopped while in operation, the equipment MN outputs non-operation as the equipment state of its own device to the operation display device DP. When the operation display device DP receives an installation state from the installation MN, the operation display device DP receives an installation name, time, and an installation state notification signal (in this embodiment, operating, non-operating, alert). Are sent to the production state management device MD. In the operation display device DP, an equipment name of the equipment MN corresponding to the operation display device DP is stored in advance.

  When the production status management device MD receives the equipment status notification signal from the operation display device DP by the communication IF unit 1, the acquisition processing unit 22 extracts the equipment name, time and equipment status from the received equipment status notification signal, A record is newly added to the equipment state information table MT stored in the state information storage unit 34, and the equipment name extracted in the equipment name field 341, the time field 342 and the equipment state field 343 in the added record Register time and equipment status. Then, when the taken-out equipment state is in operation, the acquisition processing unit 22 causes the prediction processing unit 26 to predict the operation stop time. The prediction processing unit 26 searches (selects) the processing time corresponding to the equipment name registered in the equipment name field 341 in the record newly added to the equipment state information table MT from the processing time information, The operation stop time of the equipment MN is obtained as a prediction by adding the processing time searched for to the time registered in the time field 342. Subsequently, the acquisition processing unit 22 registers the predicted operation stop time in the operation stop time field 344 of the added record. As a result, the equipment state, which is one of the classification factor states, is updated, and the latest equipment state is stored in the equipment state information storage unit 34.

  Next, acquisition of the work state will be described.

  First, at the start of processing of the work WK, when the work WK is transported to the facility MN (here, processing facility etc.) used in the process according to the order of processes, the facility MN used in the process is The current worker WM in charge brings the portable terminal TA close to the reader RD so that the terminal ID can be read from the portable terminal TA. When the portable terminal device TA is brought close to the reading device RD, in FIG. 10, the reading device RD reads the terminal ID from the portable terminal device TA and temporarily stores it (S11).

  Subsequently, the current worker WM brings the work WK close to the reader RD so that the work ID can be read from the RF tag of the work WK. When the workpiece WK is brought close to the reader RD, the reader RD reads the workpiece ID from the RF tag of the workpiece WK, and outputs the workpiece ID together with the terminal ID read in the process S11 to the operation display terminal DP (S12) .

  The operation display device DP displays any one of the standby screen, the processing-in-progress screen, and the alert screen according to the equipment state of the equipment MN corresponding to the operation display device DP. The standby screen is a menu screen that is displayed when the facility MN is not in operation, and is a menu screen for accepting any one of work start (work start), work completion (work end), and transfer start and transfer end. . The in-process screen is displayed when the facility MN is in operation, and is a screen for displaying the progress of the process of the work WK. If the current worker WM needs to operate the work WK or the facility MN with the progress of the process of the work WK, the operation instruction is also displayed on the in-process screen. The alert screen is a screen for displaying the alert when the facility MN detects an alert and an alert is input from the facility MN. Here, since the facility MN is not in operation, the standby screen is displayed on the operation display device DP.

  The current worker WM selects a work start (work start), and inputs the work start on the operation display device DP. Subsequently, when the input of the work start is received as predetermined data (S13), the operation display device DP starts as the equipment name, the terminal ID and the work ID read by the reader RD in each of the processes S11 and S12, and the work state. A work state notification signal containing medium and time is transmitted to the production state management device MD (S14).

  When the input of the work start is received, the operation display device DP instructs (outputs) the operation start to the facility MN, and displays the in-process screen. When the operation start instruction is received, the facility MN starts operation, outputs the operating condition as the facility state to the operation display device DP, and processes the work WK. The operation display device DP having received this output transmits the equipment state notification signal in operation as described above. When the processing of the work WK is completed, the facility MN stops the operation, and outputs the non-operation and the end of the process of the work WK to the operation display device DP as the facility state. The operation display device DP that has received this output transmits the equipment status notification signal in operation as described above, and displays a screen that displays the end of the processing of the work WK in the processing-in-process screen.

  On the other hand, when the production status management device MD receives the work status notification signal from the operation display device DP by the communication IF unit 1, the acquisition processing unit 22 determines the equipment name, the workpiece ID, the terminal ID, The work status and the time are taken out, and the name of the staff (the current worker name) corresponding to the taken out terminal ID is retrieved (selected) from the staff terminal correspondence information table STb. Then, the acquisition processing unit 22 newly adds a record to the planned arrival completion information table PT stored in the planned arrival completion information storage unit 33, and the work ID field 331, the time field 332, and the work state in the added record. The extracted work ID, time, and work state are registered in each of the fields 333, and the retrieved worker name (current work representative name) is registered in the current worker name field 334 in the added record. As a result, the work state which is one of the states of the classification factor is updated during the start, and the latest work state is stored in the planned arrival completion information storage unit 33.

  Second, at the end of processing of the work WK, the current worker is supposed to display the end of the processing of the work WK described above on the operation display device DP in the same manner as described above. Close to the reader RD to bring the portable terminal TA close to the reader RD. Processing S11 and processing S12 are performed according to this. This can cope with the case where the current worker at the start of the work is changed to another person at the end of the work. When the output of the end of the process of the work WK is received from the facility MN and the process S11 and the process S12 are executed, the operation display device DP displays the standby screen. For example, by providing a switch for displaying the standby screen, the standby screen can be displayed, and by holding the work ID and the terminal ID read in the process S11 and the process S12 at the time of the work start, If there is no change in the current worker WM at the end of the work, the processes S11 and S12 may be omitted.

  When the standby screen is displayed, the current worker WM selects work completion (work completion), and inputs the work completion to the operation display device DP. Subsequently, when the input of work completion is received as predetermined data (S13), the operation display device DP receives the equipment name, the terminal ID and the work ID read by the reader RD in each of the processing S11 and processing S12, and the work status not yet. A work state notification signal containing the arrival and the time is transmitted to the production state management device MD (S14).

  When the production status management device MD receives a work status notification signal from the operation display device DP by the communication IF unit 1, the production processing unit 22 operates by the acquisition processing unit 22 in the same manner as described above. As a result, the work state, which is one of the states of the classification factor, is updated as it has not arrived, and the latest work state is stored in the planned arrival completion information storage unit 33.

  Third, at the start of conveyance of the work WK, the current worker WM currently in charge of the conveyance device brings the work WK close to the reader RD and the portable terminal TA to the reader RD as described above. Get close. Processing S11 and processing S12 are performed according to this. In this case, the reading device RD and the operation display device DP may be provided, for example, in a transport device such as a forklift, a crane and a cart, and the reading device RD and the operation display device DP of the facility MN in the process are diverted ) May be.

  On the standby screen, the current worker WM selects transport start, and inputs transport start to the operation display device DP. Subsequently, when the input of conveyance start is received as predetermined data (S13), the operation display device DP receives the equipment name, the terminal ID and the work ID read by the reader RD in each of the processes S11 and S12, and the work state before. A work state notification signal containing the process completion and the time is transmitted to the production state management device MD (S14). The information on the transfer source and the information on the transfer destination may be further input to the operation display device DP, and the information may be further contained in the work state notification signal.

  When the production status management device MD receives a work status notification signal from the operation display device DP by the communication IF unit 1, the production processing unit 22 operates by the acquisition processing unit 22 in the same manner as described above. As a result, the work state, which is one of the states of the classification factor, is updated at the completion of the previous step, and the latest work state is stored in the planned arrival completion information storage unit 33.

  Fourth, at the end of the transfer of the work WK, the current worker WM of the transfer apparatus brings the work WK close to the reader RD and brings the portable terminal TA close to the reader RD, as described above. Processing S11 and processing S12 are performed according to this.

  On the standby screen, the current worker WM selects the end of transport, and inputs the end of transport into the operation display device DP. Subsequently, when the input of conveyance end is received as predetermined data (S13), the operation display device DP receives the equipment name, the terminal ID and the work ID read by the reader RD in each of the processes S11 and S12, and the work state before A work state notification signal containing the process complete and arrived and the time is transmitted to the production state management device MD (S14).

  When the production status management device MD receives a work status notification signal from the operation display device DP by the communication IF unit 1, the production processing unit 22 operates by the acquisition processing unit 22 in the same manner as described above. As a result, the work state, which is one of the states of the classification factor, is updated as the previous process is complete and has arrived, and the latest work state is stored in the planned arrival completion information storage unit 33.

  The acquisition means of each of the work state, the equipment state, and the current worker state is not limited to the above, and appropriate acquisition means may be used. For example, a map of the production site AR representing the installation site of the facility MN is stored in advance, and a plurality of antennas capable of receiving radio waves radiated from the RF tag are disposed at the top of the production site AR, for example the ceiling, By tracking the movement and stagnation of each with the plurality of antennas and referring to the map, transfer start and transfer end can be automatically detected, and pre-process completion and pre-process complete and arrived are automatically detected in the work state. Can be detected.

(Classification of production status)
In the classification of production state, the production state management device MD operates as follows. In FIG. 11, when the control processing unit 2 receives a communication signal from the network NW by the communication IF unit 1 (S21), the production state management device MD executes a process according to the received communication signal (S22). For example, when the received communication signal is a position notification signal, the production state management device MD processes as described above, whereby the personnel (current work person in charge) WM related to the latest current work person in charge state The position of the person is stored in the person-in-charge position information storage unit 35. Also, for example, when the received communication signal is the equipment state notification signal, the production state management device MD processes as described above, whereby the latest equipment state is stored in the equipment state information storage unit 34. . Also, for example, when the received communication signal is a work state notification signal, the production state management device MD processes as described above, whereby the latest work state is stored in the planned arrival completion information storage unit 33. Ru.

  Subsequently, the production state management device MD uses the extraction processing unit 23 of the control processing unit 2 to determine the type of the production state based on the latest current worker state, equipment state, and work state (S23).

  More specifically, when the communication signal received in step S21 is a position notification signal, in the present embodiment, in the position field of the person-in-charger position information table WT, the area name (AR-11 to AR-34) Since the extraction processing unit 23 first registers the area name obtained based on the reception intensity and the beacon ID contained in the position notification signal received in the process S21 according to the area name, the extraction processing unit 23 Convert to either a setup location or absent (others). For example, when the area name is AR-11, the extraction processing unit 23 converts the area name AR-11 into the operation place. Also, for example, when the area name is AR-23, the extraction processing unit 23 converts the area name AR-23 into a setup place. Further, for example, when the area name is AR-32, the extraction processing unit 23 converts the area name AR-32 into an absence. Thus, the latest current worker status is obtained from the position (location) of the latest worker (current worker) WM. Next, the extraction processing unit 23 converts the terminal ID contained in the position notification signal received in the processing S21 from the personnel terminal correspondence information table STb to a personnel name (current worker name), and this transformed personnel name The (current worker name) is converted from the equipment personnel corresponding information to the equipment name, and the latest equipment state corresponding to the converted equipment name is retrieved (selected) from the equipment state information table MT. This requires the latest equipment condition. Next, the extraction processing unit 23 obtains a work WK (work ID) corresponding to the obtained equipment name from the production plan stored in the planned arrival completion information storage unit 33, and the obtained work WK (work ID) ) Is retrieved (selected) from the planned arrival completion information table PT. By this, the latest work state can be obtained. Then, the extraction processing unit 23 determines the latest equipment status, current worker status and work status, respectively, the facility status field 311, current worker status field 312 and work status field in the production status classification information table CT. The record registered in each of the 313 is searched (selected), the type of production state registered in the production state classification field 314 in this searched record is extracted, the alert flag registered in the alert flag field 315 is extracted, and these extracted The type of production state and the alert flag are stored in the storage unit 3 as the determination result for the reception of the current communication signal (here, the position notification signal).

  When the communication signal received in step S21 is the equipment state notification signal, the extraction processing unit 23 firstly uses the latest equipment state corresponding to the equipment name accommodated in the equipment state notification signal received in step S21. Are searched (selected) from the equipment condition information table MT. This requires the latest equipment condition. Next, the extraction processing unit 23 uses the production plan stored in the planned arrival completion information storage unit 33 for the work WK (work ID) corresponding to the equipment name contained in the equipment state notification signal received in process S21. The latest work state corresponding to the obtained work WK (work ID) is found (selected) from the planned arrival completion information table PT. By this, the latest work state can be obtained. Next, the extraction processing unit 23 converts the facility name contained in the facility status notification signal received in the process S21 from the facility-personnel correspondence information to the current worker name, and corresponds to the converted current worker name. The latest current worker status to be searched is searched (selected) from the worker position information table WT through the area name. By this, the latest current worker status is obtained. Then, the extraction processing unit 23 determines the latest equipment status, current worker status and work status, respectively, the facility status field 311, current worker status field 312 and work status field in the production status classification information table CT. The record registered in each of the 313 is searched (selected), the type of production state registered in the production state classification field 314 in this searched record is extracted, the alert flag registered in the alert flag field 315 is extracted, and these extracted The type of the production state and the alert flag are stored in the storage unit 3 as the determination result for the reception of the current communication signal (here, the equipment state notification signal).

  When the communication signal received in step S21 is a work state notification signal, the extraction processing unit 23 firstly uses the latest equipment state corresponding to the facility name accommodated in the work state notification signal received in step S21. Are searched (selected) from the equipment condition information table MT. This requires the latest equipment condition. Next, the extraction processing unit 23 searches (selects) the latest work state corresponding to the work ID contained in the work state notification signal received in the process S21 from the planned arrival completion information table PT. By this, the latest work state can be obtained. Next, the extraction processing unit 23 converts the facility name contained in the work state notification signal received in the process S21 from the facility personnel correspondence information to the current worker name, and corresponds to the converted current worker name. The latest current worker status to be searched is searched (selected) from the worker position information table WT through the area name. By this, the latest current worker status is obtained. Then, the extraction processing unit 23 determines the latest equipment status, current worker status and work status, respectively, the facility status field 311, current worker status field 312 and work status field in the production status classification information table CT. The record registered in each of the 313 is searched (selected), the type of production state registered in the production state classification field 314 in this searched record is extracted, the alert flag registered in the alert flag field 315 is extracted, and these extracted The type of production state and the alert flag are stored in the storage unit 3 as the determination result for the reception of the current communication signal (here, the work state notification signal).

  Subsequently, the production state management device MD causes the extraction processing unit 23 of the control processing unit 2 to determine the type of the current production state determined in the processing S23 in the previous processing 23 and store the previous production state in the storage unit 3 It is determined whether or not the type of production state has changed by comparing with the type of (S24). As a result of the determination, if the type is changed (Yes), the production state management device MD subsequently executes the processing S25 and subsequently executes the processing S26. On the other hand, as a result of the determination, if the type is not changed (No), the production state management device MD subsequently executes the process S26.

  In the process S25, the production state management device MD generates the current production which is extracted in the process S23 by the extraction processing unit 23 to a specific terminal device preset and specified by the output processing unit 24 of the control processing unit 2. A production state notification signal containing the type of state is generated, and the generated production state notification signal is transmitted by the communication IF unit 1.

  For example, the specific terminal device (for example, the display terminal device TD) which has received the production state notification signal displays a screen (production state type display screen) for displaying the type of production state. An example is shown in FIG. The production state type display screen 101 of the example shown in FIG. 12 displays the type of production state and the like in a table format in which records are arranged in chronological order. More specifically, the production status type display screen 101 includes an equipment name display field 111 for registering and displaying the equipment name, an equipment status display field 112 for registering and displaying the equipment status, and the current worker status. The current worker status display field 113 registered and displayed, the work status display field 114 registered and displayed the work status, the production status classification display field 115 registered and displayed the type of production status, and work management Name display field 116 for registering and displaying a person's name, current work name display field 117 for registering and displaying a current work person name, and registering and displaying the position of the current work person WM Position display field 118 and a workable person name display field 119 for registering and displaying a workable person name, each time a production status notification signal is received With a code. Each time the production status notification signal is received, a record is added at the top, and each data contained in the production status notification signal is registered and displayed in the fields 111 to 119 of the added record. For this reason, the topmost record is the newest in time, each record becomes sequentially chronologically as it goes to the bottom, and the bottommost record is oldest in time. In order to display the production status type display screen 101, in the present embodiment, not only the type of production status is accommodated in the production status notification signal, but it is used when determining the type of the production status. The equipment name, equipment state, current work person state, work state, current work person name, current position of the work person WM are further accommodated, and based on the current work person name, the equipment personnel corresponding information table STa The name of the work manager and the name of the person who can work are further stored.

  When the equipment state is in operation, the output processing unit 24 further accommodates the predicted operation stop time in the production state notification signal, and the production state type display screen 101 accommodates the production state notification signal. The system may further include an estimated operation stop time display field for registering and displaying the operation stop time. According to this, the user who handles the terminal device TA, TD, and PC is notified of the predicted operation stop time, and the user effectively applies the time until the predicted operation stop time to, for example, other tasks. It can be used to Therefore, this can further improve the efficiency of production.

  In the process S26, whether or not the output state processing unit 24 of the control processing unit 2 needs to warn (notify) the type of the production state to the predetermined terminal devices TA, TD, and PC whether or not the production state management device MD judge. More specifically, the output processing unit 24 determines whether it is necessary to warn (notify) based on the alert flag extracted in the process S23. As a result of this determination, if the alert flag is "1", it is determined that it is necessary to warn (notify) (Yes), and the production state management device MD subsequently executes the process S27, and then the current communication is performed. The present processing accompanied by the reception of the signal is ended. On the other hand, as a result of the determination, if the alert flag is "0", it is determined that it is not necessary to warn (notify) (No), and the production state management device MD performs the main processing associated with the reception of the current communication signal. Finish.

  In the process S27, the production state management device MD causes the output processing unit 24 of the control processing unit 2 to transmit a warning notification signal (production status notification signal) to the predetermined terminal devices TA, TD, and PC. More specifically, the output processing unit 24 first uses the terminal devices TA, TD, and the like corresponding to the facility MN as a classification factor used when extracting the type of the current production state by the extraction processing unit 23 in step S23. The PC is taken out from the notification destination information stored in the notification destination information storage unit 32. More specifically, the output processing unit 24 first selects the name of the personnel corresponding to the facility name used when the type of the current production state is extracted by the extraction processing unit 23 in step S23 The name and the person who can work can be searched (selected) from the equipment-personnel correspondence information table STa. Next, the output processing unit 24 searches (selects) a terminal ID corresponding to the retrieved (selected) personnel name from the personnel terminal correspondence information table STb. Next, the output processing unit 24 takes out from the storage unit 3 the communication addresses of the terminal devices TA, TD, and PC having the searched (selected) terminal ID. Next, a warning notification signal (production status notification signal) is generated at the extracted communication address. Then, the output processing unit 24 transmits the generated warning notification signal (production state notification signal) by the communication IF unit 1.

  The predetermined terminal devices TA, TD, and PC that have received the warning notification signal (production status notification signal) display the above-described production status type display screen 101 shown in FIG. 12, for example. As a result, the personnel (current work manager, work manager and work enabler) WM related to the predetermined terminal device TA, TD, PC are the production state type display displayed on the predetermined terminal device TA, TD, PC By referring to the screen 101, it is possible to objectively grasp the type of production state, and it is possible to take an action according to the type of production state.

  As described above, the production state management system MS, the production state management device MD, and the production state management method implemented in this according to the present embodiment store production state classification information in advance and use the state of the acquired classification factor. The type of the corresponding production state is extracted from the production state classification information and output. For this reason, with respect to the same type in the classification factor, the same type in the production state can be determined, and the possibility of erroneous determination by the user can be reduced. Therefore, the production state management system MS, the production state management device MD, and the production state management method can support the determination of the production state by the user, and the user is more appropriate by referring to the type of the determined production state. Because we can act, we can achieve more efficient production.

  The production state management system MS, the production state management device MD, and the production state management method transmit a production state notification signal to the terminal device. For this reason, the terminal equipment TA, TD, PC which has received the production state notification signal outputs the type of the production state accommodated in the terminal equipment TA, TD, the user who handles the terminal equipment TA, TD, PC, the production The type of state is notified. Therefore, the production state management system MS, the production state management device MD, and the production state management method can support the determination of the production state by the user who handles the terminal devices TA, TD, and PC, and the type of the production state determined Since the user can take more appropriate action by referring to this, it is possible to achieve more efficient production. In addition, since the production status notification signal is notified to the terminal devices TA, TD, and PC, the current worker WM and the like can take charge of a plurality of facilities MN, thereby further improving production efficiency.

  The production state management system MS, the production state management device MD, and the production state management method transmit the production state notification signal when the type of production state changes. Therefore, the user handling the terminal devices TA, TD, and PC is notified of the change in the type of production state, and the user can take appropriate action according to the type of production state after the change. Therefore, the production state management system MS, the production state management device MD, and the production state management method can achieve more efficient production. For example, when the processing of the work WK by the facility MN ends, the production state notification signal is transmitted, and the user can promptly carry out the process of transporting the work WK to the place of the next process. Also, for example, when the operation of the facility MN is stopped before the scheduled time for the processing of the work WK by the facility MN to end, the user can promptly implement the process of recovering the stopped facility MN. As a result, it is possible to reduce the dead time of equipment stop and to achieve more efficient production.

  The production state management system MS, the production state management device MD, and the production state management method transmit the production state notification signal further accommodating the state of the work. Therefore, the user who handles the terminal devices TA, TD, and PC is notified of the work state, and the user can take an action according to the work state. For example, if the work state is not yet started, the person in charge of the work WK can be urged to start the work, or if the work state is the previous process completion, the next process can be prepared. Therefore, the production state management system MS, the production state management device MD, and the production state management method can achieve more efficient production.

  The production state management system MS, the production state management device MD, and the production state management method transmit the production state notification signal further accommodating the location of the personnel WM. Therefore, the user who handles the terminal devices TA, TD, and PC is notified of the location of the personnel WM, and the user can take an action according to the location of the personnel WM. For example, while the work WK has arrived at the facility, if the current worker WM of the work WK is not present, the current worker WM can be notified of the arrival of the work WK to prompt the start of the work. Therefore, the production state management system MS, the production state management device MD, and the production state management method can achieve more efficient production.

  In the above embodiment, the production status notification signal (including the warning notification signal) is transmitted by the communication IF unit 1 immediately after the output processing unit 24 changes the type of the production status. The state notification signal (including the warning notification signal) may be transmitted by the communication IF unit 1 after a predetermined time has elapsed from when the type of the production state changes by the output processing unit 24. If the current worker WM or the like is located at the operation location, the current worker WM or the like can cope with the situation without notification. According to this, since the production status notification signal is notified after a predetermined time has passed, the current worker WM or the like is given the allowance for the above-mentioned handling.

  In the above embodiment, the type of production status is extracted from the status of equipment, the status of personnel WM (the position of personnel WM in the above (for example, the location of current personnel in charge) and the status of work). It may be extracted from two or more of them. That is, the plurality of types of classification factors include a plurality of types of equipment involved in the production of a product, personnel involved in the production of the product, and work involved in the production of the product.

  For example, the plurality of classification factors are equipment involved in the production of a product and personnel involved in the production of the product, and types of production status are status of equipment and status of personnel WM (in the above description It may be extracted from the location of the worker WM)). For example, as shown in FIG. 4, when the equipment status is "in operation" and the current worker status is "absent", "automatic machine processing" is extracted as the production status, and the equipment status is "in operation". If "in operation" and the current worker status is the setup location, "in charge of the person in charge" is extracted as the production status, and the facility status is "in operation" and the current worker in charge When the state is the operation place, “in-person in operation” is extracted as the production state.

  Also, for example, the plurality of classification factors may be equipment related to the production of a product and a work related to the production of the product, and the type of production state may be extracted from the equipment state and the work state.

  Further, in the above-described embodiment, after the output processing unit 24 transmits the production state notification signal (including the warning notification signal) to the communication IF unit 1, the changed production state of the type continues for a predetermined time. If it is, the production status notification signal (including a warning notification signal) may be retransmitted to the communication IF unit 1. If the type of production condition to be dealt with has not been dealt with, the user can be urged to take the above-mentioned countermeasure.

  Further, in the above-described embodiment, the production state management device MD further includes a work position acquisition unit that acquires the location of the work WK as a classification factor used when extracting the type of the production state by the extraction processing unit 23. When the output processing unit 24 generates the production state notification signal (including the warning notification signal), the output processing unit 24 acquires the work position acquisition unit when the type of the production state extracted by the extraction processing unit 23 changes. It may further accommodate the location of the workpiece. According to this, the user who handles the terminal devices TA, TD, and PC is notified of the location of the work WK, and the user can predict the time when the work WK arrives at the user's origin, and the estimated arrival time For example, it is possible to effectively utilize the time until, for example, other tasks. Therefore, this can further improve the efficiency of production. The work position acquisition unit is functionally configured in, for example, the control processing unit 2 and acquires the location of the work WK based on data contained in each communication signal. For example, if the work state accommodated in the work state notification signal is under development, the location of the work WK is the installation location of the equipment MN having the equipment name accommodated in the work state notification signal. Also, for example, if the work state accommodated in the work state notification signal has not arrived, the location of the work WK processed by the equipment MN is the location of the equipment MN having the equipment name accommodated in the work state notification signal. The location of the workpiece WK, which is the location of the installation and is processed next by the facility MN, is determined by referring to the location of the facility MN having the facility name accommodated in the work status notification signal and the production plan. It is the installation site of the equipment MN of the front process or the installation site of the equipment MN of the front process to be determined. Further, for example, if the work state accommodated in the work state notification signal is the completion of the previous process, the location of the work WK processed by the equipment MN is the equipment MN having the equipment name accommodated in the work state notification signal. Between the placement site of the next process and the placement site of the equipment MN of the next process determined by referring to the production plan. Further, for example, if the work state accommodated in the work state notification signal is the previous process complete and has arrived, the location of the work WK processed by the equipment MN concerned is the equipment name accommodated in the work state notification signal. The location of the installation MN (ie, the arrangement of the facility MN of the next process with respect to the process to be processed by the facility MN having the facility name accommodated in the work status notification signal accommodating the work status notification signal Place). Alternatively, when the information of the transfer source and the information of the transfer destination are further input to the operation display device DP and the information is further accommodated in the work state notification signal, the location of the work WK is accommodated in the work state notification signal. The determination can be made directly from the information of the carried source and the information of the carried destination.

  Further, in this case, the production state type display screen 101 may further include a work location display field for registering and displaying the location of the work WK contained in the production state notification signal.

  Further, in the above-described embodiment, the position (location) of the personnel (current worker) WM is obtained by using the marking device BC, but the present invention is not limited to this. The position of the personnel WM may be determined. In addition, the method may be selected according to the characteristics of the production place AR.

  For example, GPS (Global Positioning System) may be used. In this case, the personnel WM carries a GPS receiver. Alternatively, the portable terminal device TA carried by the staff WM further has a GPS reception function. The GPS receiver (or the portable terminal device TA with the GPS reception function) receives the GPS signal from the GPS satellite at a predetermined time interval set in advance, locates the position of the own device, A communication signal (position notification signal) containing the latitude and longitude) is transmitted to the production state management device MD via the operation display device DP or directly. The production state management device MD, as one of the various predetermined data, includes a production location AR (12 each of the areas AR-11 to AR34 in the above example) and a latitude and a longitude (for example, the production location AR) indicating its position. The GPS area correspondence relation information representing the correspondence relation with the set of latitude and longitude, etc. representing the outline of the area is stored in the storage unit 3 in advance, and when the position notification signal is received, the GPS area correspondence relation information A production place AR (12 areas AR-11 to AR34 in the above-mentioned example) including the position (the position of the staff WM) accommodated in the received position notification signal is determined. Use of such GPS is preferable when specifying a more detailed position or when specifying a position in a wider production area.

  For example, an image may be used. In this case, in order to obtain the image, the camera may be located at a position (for example, above the wall or ceiling of the production place AR) where the production place AR (in the above example, 12 areas AR-11 to AR34) can be viewed. The camera acquires (captures) an image at predetermined time intervals set in advance, and a communication signal (position notification signal) containing the acquired image is transmitted via the operation display device DP. Alternatively, it directly transmits to the production state management device MD. The personnel WK can identify a predetermined mark (e.g., a figure, a color, a combination thereof, etc.) from the camera so that the position can be identified from the image (e.g. Prepare for the shoulder upper part etc.). The production state management device MD, as one of the various predetermined data, includes a production place AR (12 areas AR-11 to AR34 in the above example) and an area on an image acquired by the camera For example, the table image area correspondence information is stored in advance in the storage unit 3 in correspondence with the set of pixels corresponding to the production place AR, etc., and the position notification signal is received when the position notification signal is received. The predetermined mark is recognized from the image stored in the image storage area, and the production location AR (12 areas AR-11 to AR34 in the above example) including the recognized mark is obtained from the image area correspondence information. The predetermined mark may further have a function of an identifier (personnel ID) for identifying the person WK and identifying the person WK. For example, a red helmet is assigned to the personnel WM whose personnel name is "OPA", and a green helmet is assigned to the personnel WK whose personnel name is "OPB". A personnel WK whose personnel name is "OPC" is blue Assign a helmet. This enables identification of the personnel WK from the image. Use of such an image is preferable, when it can look over production place AR without a blind spot from a camera.

  In addition to the methods exemplified above, there are various methods, and a plurality of methods may be combined. For example, the marking device BC and the camera are combined, and the position of the staff WM is roughly specified (detected) from the reception intensity of the beacon, and the position of the staff WM is more detailed from the image portion of the camera at this roughly specified position. It is identified. Also, for example, the marking device BC and the GPS are combined. According to this, when using the GPS, the position of the personnel WM can be specified (detected) in a wider range than when using the marking device BC, so the location where the personnel WM deviates from the production location AR, eg, the production location Even when traveling to a different place (others) from the AR factory, the position of the staff WM can be identified.

It should be recognized that it is possible. Therefore, unless a change or improvement implemented by a person skilled in the art is at a level that deviates from the scope of the claims set forth in the claims, the change or the improvement is the scope of the rights of the claim It is interpreted as being included in
