"XX or YY" is not limited to either XX or YY, but may include both XX and YY. This also applies when there are three or more selective elements. "XX" and "YY" are any element (e.g., any information).

[0011] <Embodiment> (composition) FIG. 1 is a block diagram illustrating an example of a driving assistance system according to an embodiment. The operation support system 1 includes a manager terminal 10 and an operator terminal 20. The number of the manager terminal 10 and the operator terminal 20 is not limited to one, and the operation support system 1 may include a plurality of manager terminals 10 and a plurality of operator terminals 20. The manager terminal 10 is used by a manager who instructs the operation of a plant or the like, and the operator terminal 20 is used by an operator who actually performs the operation based on the instructions of the manager. The manager terminal 10 and the operator terminal 20 are communicably connected via an AP (access point) 30. The manager terminal 10 and the operator terminal 20 exchange information such as instruction information instructing the operation, repetition information equivalent to repetition of the instruction, permission information permitting the operation in response to the repetition or reconfirmation request information requesting reconfirmation of the repetition content, completion report information reporting the completion of the operation, completion approval information indicating that the final confirmation has been made for the completion report, and return information requesting reconfirmation for the completion report, to support communication between the manager and the operator in the operation of the plant. In addition, the manager terminal 10 and the operator terminal 20 support the operation of the plant by transmitting, receiving, and displaying the above information regarding the operation to be actually performed while displaying the operation procedure manual.

[0012] The manager terminal 10 is configured with a computer such as a PC (personal computer), a tablet terminal, etc. The manager terminal 10 includes a display unit 11, an input receiving unit 12, a control unit 13, a storage unit 14, and a communication unit 15. The display unit 11 is configured using a display device such as a liquid crystal display, an organic EL (Electro-luminescence) display, or a touch panel. The display unit 11 displays any information based on an instruction from the control unit 13. For example, the display unit 11 displays an operating procedure manual, instruction information, etc. The input reception unit 12 receives information input by an administrator's operation. The input reception unit 12 outputs the received input information to the control unit 13. The control unit 13 controls the display of the display unit 11, writes information to the storage unit 14, and controls reading information from the storage unit 14. The storage unit 14 is configured using a storage device such as a hard disk drive (HDD) or a flash memory, and stores, for example, an operating procedure manual, a program for a web server, etc. The communication unit 15 communicates with other devices via the AP 30.

[0013] The operator terminal 20 is configured with a mobile terminal such as a smartphone, a computer such as a tablet terminal, etc. The operator terminal 20 includes a display unit 21, an input receiving unit 22, a control unit 23, a storage unit 24, and a communication unit 25. The display unit 21 is configured using a display device such as a liquid crystal display, an organic EL display, or a touch panel. The display unit 21 displays any information based on an instruction from the control unit 23. For example, the display unit 21 displays an operating procedure manual, instruction information, etc. The input reception unit 22 receives input of instruction operations by an administrator. For example, the input reception unit 22 receives information input by an operator's operation, and outputs the received input information to the control unit 23. The control unit 23 controls the display of the display unit 21, writes information to the memory unit 24, and controls reading information from the memory unit 24. The memory unit 24 is configured using a storage device such as a HDD or a flash memory. The communication unit 25 communicates with other devices via the AP30.

[0014] The manager terminal 10 has a function of importing an electronic file of an operating procedure manual and generating a screen displaying the operating procedure manual as shown in FIG. 3 and the like. The generated screen is, for example, electronic data in HTML format. The manager terminal 10 is configured such that the imported operating procedure manual is displayed when the control unit 13 starts a Web server and accesses a predetermined URL (Uniform Resource Locator). The manager and the operator access the predetermined URL using the manager terminal 10 and the operator terminal 20, respectively, and operate the plant while displaying the same operating procedure manual on the display units 11 and 21, respectively. FIGS. 2 to 5 show examples of screens displayed on the display units 11 and 21, such as an operating procedure manual and an operating procedure manual selection screen. Various screens and child screens that display pop-ups, as shown below, are generated by the control units 13 and 23, and displayed on the display units 11 and 21.

[0015] (Display of Instructions) FIG. 2 shows an example of a request screen for an operation manual. In a plant, there are many operation manuals for the operating conditions of the plant, such as during normal operation and when an accident occurs, the operation purpose, and the equipment and facilities to be operated. As shown in the figure, a large number of operation manuals are organized and displayed in a list on the request screen 100. The purpose and subject of the operation manual are displayed in "XX-use" such as "Operation Manual 1 (for XX)", so that it is possible to know at a glance what kind of operation manual it is. "Operation Manual 1 (for XX)" and the like are buttons, and each button is associated with the URL of the operation manual displayed on the button. When each button is selected or pressed, the operation manual displayed on the button is displayed. The example shown in FIG. 2 is a selection screen for operation manuals used for responding to an accident, among classifications such as during normal operation and when an accident occurs. For example, when "Operation Manual 21 (for XX)" is selected on the request screen 100, Operation Manual 21 is displayed. This allows the user to quickly view the operation manual in which the desired procedure is described.

[0016] FIG. 3 shows an example of a procedure manual display screen 200 displaying a procedure manual 21. The procedure manual display screen 200 includes a name display field 201, a progress status display button 202, buttons 203a to 203d for calling up other procedure manuals, and a display field 204 for displaying operations described in the procedure manual. The name display field 201 displays the role and name of the terminal user. The role is displayed as manager or operator, and in the case of an operator, it is displayed which equipment or system the operator is in charge of. For example, the following explanation will be given assuming that there are an operator for equipment 1 and an operator for equipment 2. The display field 204 displays the contents of the procedure manual 21 selected on the request screen 100. The display field 204 has the items of "Order", "Person in charge", "Operation", "Check and precautions", and "Response instructions", where "Order" displays the order in which the operations are to be performed, "Person in charge" displays the type and role of the person in charge of the operation, "Operation" displays the content of the operation to be performed, "Check and precautions" displays precautions for the operation, and "Response instructions" displays a response instruction button 205. The response instruction button 205 is used when the manager instructs the operator in charge to perform a certain operation. FIG. 3 shows an example of the display of the procedure manual displayed on the display unit 11 of the manager terminal 10, and in the case of the operator terminal 20 (display unit 21), a completion report button is displayed in the "Response instructions" item. In the operator terminal 20 used by the operator of facility 1, the report completion button is displayed only for operations performed by the operator of facility 1 (operations for which the equipment 1 operator is displayed in the "Person in charge" item), and in the operator terminal 20 used by the operator of facility 2, the report completion button is displayed only for operations performed by the operator of facility 2. The functions of these buttons will be described later. For items other than "person in charge", the contents of the procedure manual 21 are displayed regardless of whether it is the manager terminal 10 or the operator terminal 20, or whether it is the operator of equipment 1 or the operator of equipment 2. By performing a predetermined operation, it is possible to change the displayed contents of the display field 204 by scrolling, page forwarding, etc., and to display operations prior to the currently displayed order 8 or operations after order 11. The operations of orders 8 to 10 illustrated in Fig. 3 are part of the procedure of identifying damaged equipment and isolating the damaged equipment.In this specification, a "procedure" is a rough unit of work consisting of one or more operations, and an "operation" is a term indicating a more specific and detailed unit of work. As an example, in a plant to be operated, operations in orders 8 to 10 are about to be carried out, and the previous operations in orders 1 to 7 have already been completed. As will be explained later, when an operation is completed, the status of that operation is set to "completed." In this state, when the manager selects the progress display button 202, the control unit 13 displays a progress display screen 300 showing the flow of operations described in the procedure manual 21.

[0017] -Progress display FIG. 4 shows an example of the progress status display screen 300. As shown in the figure, the progress status display screen 300 displays the flow of procedures in the form of a flowchart. Procedures within a range enclosed by a frame 301 are procedures that have already been performed and have a status of completed. These procedures are displayed, for example, in gray. Procedures within a range enclosed by a frame 302 are procedures that are being performed. Procedures that are being performed are displayed, for example, in yellow (shown in a thick frame in FIG. 4). Procedures within a range enclosed by a frame 303 are procedures that have not been performed. Procedures that have not been performed are displayed, for example, in green. By referring to the progress status display screen 300, the manager can grasp the progress of procedures that must be performed based on the procedure manual 21, where the currently performed procedure is located in the overall flow, the flow of the remaining procedures, and the like. In the same manner, the operator can call up the progress status display screen 300 from the procedure manual display screen 200 displayed on the operator terminal 20.

[0018] -Display of procedures according to equipment status Return to FIG. 3. Below the operation of step 8, a procedure selection field 206 for each situation is displayed. This field is displayed to select which procedure to display when procedures are divided according to the operating status, damage status, etc. of the equipment and facilities of the plant even in one procedure manual. FIG. 3 shows an example in which the procedure changes depending on which of the facilities 1-A to 1-D is the damaged facility, and shows the procedure when the facility 1-A is selected. For example, when the facility 1-B is selected in the procedure selection field 206 for each situation, the display of "Isolate the facility 1-A in the following procedure. (1) Set the controller of valve A..." in the operation of step 10 is switched to "Isolate the facility 1-B in the following procedure. (1) Set the controller of valve B...". This function makes it possible to display only the procedures required according to the situation of the plant to be operated. In the same way, the operator can display only the procedures suitable for the situation of the plant from the procedure selection field 206 for each situation on the procedure manual display screen 200 displayed on the operator terminal 20.

[0019] -Display multiple instructions When the administrator presses the button 203d on the procedure manual display screen 200 illustrated in FIG. 3, the contents of the procedure manual 31 can be displayed in addition to the procedure manual 21. FIG. 5 shows an example of the procedure manual display screen 200 when the procedure manual 21 and the procedure manual 31 are displayed side by side. The procedure manual 21 is displayed in the display field 204 on the left side of the procedure manual display screen 200, as in FIG. 3, and the procedure manual 31 is displayed in the display field 204a on the right side. In the event of an accident, it may be necessary to check two types of procedure manuals at the same time depending on the event that has occurred. Paper procedure manuals are thick and may be difficult to handle in a limited space, but as illustrated in FIG. 5, by displaying two procedure manuals side by side on the display unit 11 at will, it becomes easy to check the two procedure manuals. When two procedure manuals are used at the same time, it is possible to select one of the procedure manuals and display it in full screen by the administrator's operation (or by the operator's operation in the case of the operator's terminal 20), switch the display to the procedure manual on the non-selected side, or switch to display the two procedure manuals side by side again. Although not shown in the figures, two operating instructions can be displayed side by side in the vertical direction when checking the operating instructions on a vertically long screen such as a smartphone. Also, two operating instructions can be displayed side by side by a similar operation on the operator terminal 20. The number of operating instructions that can be displayed simultaneously is not limited to two, and may be three or more.

[0020] ·Display incomplete operations In the procedure manual 31 displayed in the display field 204a of FIG. 5, the operations in the order 10 are subdivided into (1) to (4), of which (1), (2), and (4) are operations performed by the operator of the equipment 1, and (3) is an operation performed by the operator of the equipment 2. The numbers (1) to (4) indicate the order of the operations, and it is assumed that each operation will be performed in this order. However, among them, there are some operations that can be skipped and the next operation can be performed first. The example of the display field 204a shows that the operator of the equipment 1 performed the operation (4) before the operator of the equipment 2 performed (3), and the response was completed. The control unit 13 displays the operations (1), (2), and (4) for which the response has been completed in gray. In addition, the control unit 13 displays the words "Response Completed" and the completion time (for example, "2021 / 5 / 1 10:00") in place of the response instruction button 205 in the "Response Instruction" item of the operation for which the response has been completed. Furthermore, the control unit 13 displays a display in the forgetting prevention display field 207 notifying that there is a skipped operation (3). If there is a skipped operation, the same display is also displayed on the operator terminal 20. Note that, if the operations (3) to (4) must be performed in this order, the control unit 13 may perform display control such as not displaying the response instruction button 205 in the "Response Instruction" item of the operation (4) or making it impossible to press the button until the response to the operation (3) is completed. As described later, the performance of an operation by an operator begins with a work instruction using the response instruction button 205. By disabling the response instruction button 205, the performance of the operation can be prevented.

[0021] -Setting non-execution operations Depending on the situation of the plant, there may be cases where a certain operation does not need to be performed or should not be performed. In such cases, the procedure that is not to be performed can be hidden to prevent erroneous operation. The sequence 12 in the display field 204a in FIG. 5 is a procedure that is not to be performed. For example, when the administrator performs a predetermined operation (double-click, long press, etc.) on a row in which a procedure that is not to be performed is displayed, the control unit 13 displays a child screen (not shown) in which a non-execution button is displayed, and when the administrator presses or selects the non-execution button, the operation of the row is hidden. Also, when the administrator performs a predetermined operation on the hidden row of sequence 12, the control unit 13 displays a child screen (not shown) in which a non-execution cancellation button is displayed, and when the administrator presses or selects the non-execution cancellation button, the operation of the row is redisplayed. The function of setting and canceling this non-execution procedure is a function that only the administrator terminal 10 has.

[0022] · Display of reference materials In addition, the specific operation details and wording of precautions displayed in the "Operation" and "Confirmation and Precautions" items in display field 204 are linked to related sections of other instruction manuals and reference materials as necessary, making it easy to switch between instruction manuals and check reference information.

[0023] In this way, in this embodiment, by providing various functions to the electronic procedure manual, convenience exceeding that of a paper procedure manual is realized. In addition, while a large number of thick procedure manuals need to be stored and carried around in the case of a paper procedure manual, by making it possible to refer to the procedure manuals using a terminal device, portability and operability can be improved.

[0024] (3-way communication support function) Next, a method for realizing a three-way communication style conversation by exchanging messages between the manager terminal 10 and the operator terminal 20 will be described with reference to Figs. 6 to 9. For example, a manager and an operator are monitoring a plant in the same control room. The manager issues instructions on the next procedure from the operation command desk, and the operator operates the central control panel based on the instructions to perform operation.

[0025] For example, when performing an operation of order 8, the manager first presses the corresponding instruction button 205 of order 8. The control unit 13 pops up a child screen 210 as shown in FIG. 6. The child screen 210 displays a message to confirm whether to instruct the operation of order 8. The manager presses the instruction button 210a when instructing, and presses the cancel button 210b when canceling the instruction. When the instruction button 210a is pressed, a child screen 211 is popped up on the procedure manual display screen 200′ on the display unit 21 of the operator terminal 20 as shown in FIG. 7. When the cancel button 210b is pressed, the child screen 211 is not displayed. The child screen 211 is displayed only on the operator terminal 20 linked to the operator of the equipment 1 who is in charge of the operation of order 8, and is not displayed on the operator terminal 20 linked to the operator of the equipment 2 who is not in charge of the operation of order 8. The transmission and reception of information related to the three-way communication described below is also performed only between the manager terminal 10 and the operator terminal 20 linked to the operator of the facility 1. When issuing an operation instruction of step 8, the manager, for example, presses the instruction button 210a while reading out the instruction content displayed on the child screen 210. Pressing the instruction button 210a corresponds to an instruction (transmission) of three-way communication.

[0026] The child screen 211 of the operator terminal 20 notifies the operator that instructions have been received from the manager, and when the operator presses a confirmation button 211a, the child screen 211 is hidden, and a child screen 212 showing the instructions from the manager is popped up on the display unit 21. A message instructing the operator to perform the operation in order 8 is displayed on the child screen 212. The operator, for example, presses a repeat button 212a while reading out the instructions displayed on the child screen 212. Pressing the repeat button 212a corresponds to repeating in three-way communication.

[0027] When the repeat button 212a is pressed, a sub-screen 213 is popped up on the procedure manual display screen 200 on the display unit 11 of the manager terminal 10, as shown in FIG. 8. The sub-screen 213 displays the previously instructed content (operation of order 8). The manager compares and confirms the instruction content displayed on the sub-screen 213 with the content repeated by the operator. If there is no difference between the content repeated by the operator and the instruction content, the manager presses the allow button 213a. If there is a difference between the content repeated by the operator and the instruction content, and there is a suspicion that there is a problem with the operator's understanding, the manager presses the reconfirm button 213b. Pressing the allow button 213a or the reconfirm button 213b corresponds to confirmation of the three-way communication.

[0028] When the permission button 213a is pressed, a child screen 214 is popped up on the display unit 21 of the operator terminal 20 as shown in FIG. 9. When the operator checks the text on the child screen 214 and confirms that the manager has permitted the operator to perform the operation of order 8, the operator presses the OK button 214a to hide the child screen 214. The operator checks the operation content of order 8 with reference to the procedure manual display screen 200′ on the display unit 21 and performs the operation. On the other hand, when the reconfirmation button 213b is pressed, a child screen 215 as shown in FIG. 9 is popped up on the display unit 21. The operator checks the text on the child screen 215 and re-repeats the operation content of order 8, while pressing the re-repeat button 215a to hide the child screen 215. When the operator re-repeats, the child screen 213 described in FIG. 8 is displayed again on the manager terminal 10, and the manager checks the re-repeat content and the instruction content. If the recited content does not match the command content, the display of the child screen 215 (FIG. 9) and the child screen 213 (FIG. 8) are repeated until they match.

[0029] As described above, according to this embodiment, it is possible to realize three-way communication by exchanging and displaying information between the manager terminal 10 and the operator terminal 20. This allows the manager and the operator to visually confirm the contents of instructions to each other. In addition, by performing three-way communication by voice as in the past in parallel with the transmission and reception of information, the contents of instructions can be confirmed using both vision and hearing. This makes it easier to notice each other's misunderstandings, and prevents miscommunication and human error. In addition, the manager transmits instruction information by pressing the corresponding instruction button 205 provided at the location where the operation of the instruction target is displayed on the procedure manual display screen 200. Meanwhile, the operator checks the instruction content displayed on the procedure manual display screen 200' (child screen 212). By giving instructions and checking based on the procedure manual, both the manager and the operator can check the contents of the instructions while referring to the procedure manual, so that erroneous instructions and operations can be prevented in advance. In addition, the instruction information instructed by the manager is displayed only on the operator terminal 20 of the operator who performs the operation of the instruction target, so that it is possible to prevent a situation in which an operation outside the operator's responsibility is mistakenly performed.

[0030] (Implementation report support function) Next, with reference to Figures 10 to 12, a method for realizing communication between the manager terminal 10 and the operator terminal 20 regarding a completion report of an operation after an operator has performed an permitted operation via three-way communication will be described.

[0031] For example, when an operator completes the operation of order 8 and reports it, the operator presses the completion report button 208 of order 8. The control unit 23 pops up a child screen 216 as exemplified in FIG. 10. The child screen 216 displays a message for confirming whether or not to report the completion of order 8. The completion report button 208 of order 8 is displayed only on the operator terminal 20 associated with the operator in charge of the equipment 1, and is not displayed on the operator terminal 20 associated with the operator in charge of the equipment 2. The operator presses the report button 216a when reporting the completion, and presses the cancel button 216b when canceling. When the report button 216a is pressed, a child screen 217 is popped up on the procedure manual display screen 200 on the display unit 11 of the manager terminal 10, as exemplified in FIG. 11. When the cancel button 216b is pressed, the child screen 217 is not displayed. The manager checks the state of the plant to confirm whether the operation of order 8 has been performed. If it is confirmed that the operation of order 8 has been performed, the administrator presses the approve button 217a. If it is not confirmed that the operation of order 8 has been performed, the administrator presses the send back button 217b.

[0032] When the approval button 217a is pressed, a child screen 218 as exemplified in FIG. 12 is popped up on the display unit 21 of the operator terminal 20. When the operator checks the child screen 218 and confirms that the manager has approved the completion report of the order 8, the operator presses the OK button 218a to hide the child screen 218. When the completion report is approved, the control unit 13 sets the status of the operation of the order 8 to "completed". When the completion report is approved, the control unit 13 sets the status of the operation of the order 8 to "completed". In addition, when the completion report is approved, the "Response instruction" item of the order 8 of the procedure manual 21 displayed on the manager terminal 10 and the operator terminal 20 displays the wording "Response completed" and the response completion time exemplified in the display field 204a of FIG. 5 instead of the response instruction button 205 and the completion report button 208. In addition, the wording "Response completed" and the like are also displayed on the operator terminal 20 linked to the operator of the equipment 2 who is not in charge of the order 8. This allows the operator of the equipment 2 to grasp the implementation status of the operation of the operator of the equipment 1. Similarly, when the completion report of the operation performed by the operator of facility 2 is approved, the operator terminal 20 used by the operator of facility 1 also displays a message such as "Response Completed" for that operation. This allows the manager and all operators to grasp the status of each other's operations.

[0033] On the other hand, when the send back button 217b is pressed, a child screen 219 as shown in FIG. 12 is popped up on the display unit 21. The operator sees the child screen 219, understands that the completion report of order 8 has been sent back, and presses the OK button 219a to hide the child screen 219. The operator checks the state of the plant and the operation content performed by the operator, takes action as necessary, and presses the completion report button 208 again. When the completion report is sent back, the display of the child screen 216 (FIG. 10), child screen 217 (FIG. 11), and child screen 219 (FIG. 12) is repeated until the implementation of order 8 is confirmed by the manager (until the completion report is approved). This makes it possible to manage the progress of the procedure in accordance with the procedure manual.

[0034] (operation) Next, the operation of the driving assistance system 1 will be described with reference to FIGS. 13 shows the flow of operations of the manager terminal 10 and the operator terminal 20 when performing three-way communication. It is assumed that a request screen 100 is displayed on the display units 11 and 12 by operations of the manager and the operator. In the manager terminal 10, the input reception unit 12 receives the selection of the procedure manual presented on the request screen 100 (step S11). The control unit 13 displays the procedure manual display screen 200, which displays the selected procedure manual, on the display unit 11 (step S12). In the operator terminal 20, the input reception unit 22 receives the selection of the procedure manual from the request screen 100 (step S11'). The control unit 23 accesses the manager terminal 10 through the communication unit 25 and requests the selected procedure manual. The control unit 13 reads out the procedure manual display screen 200' formatted for the operator from the storage unit 14 and transmits it to the operator terminal 20. The control unit 23 acquires the procedure manual display screen 200' through the communication unit 25 and displays it on the display unit 21 (step S12').

[0035] Next, the manager selects an operation to be performed from the procedure manual display screen 200, and presses the corresponding instruction button 205 for the selected operation. The control unit 13 uses the communication unit 15 to transmit instruction information (for example, information corresponding to the child screens 211 and 212 in FIG. 7) instructing the execution of the selected operation to the operator terminal 20 linked to the operator who performs the operation (step S13). Information on the transmission destination (IP address, etc.) of the operator terminal 20 linked to the operator who performs the operation is registered in advance in the storage unit 14. In the operator terminal 20, the control unit 23 acquires the instruction information through the communication unit 25, and displays the instruction information on the display unit 21 (step S14). For example, the control unit 23 first displays the child screen 211 in FIG. 7, and when the confirmation button 211a is pressed, displays the child screen 212.

[0036] Next, the operator presses the repeat button 212a on the child screen 212. The control unit 23 transmits the repeat information (for example, information indicating that the repeat button 212a has been pressed) to the manager terminal 10 through the communication unit 25 (step S15). In the manager terminal 10, the control unit 13 acquires the repeat information through the communication unit 15 and displays the repeat information on the display unit 11 (step S16). For example, the control unit 13 displays the child screen 213 displaying instruction information corresponding to the repeat information. If the manager confirms that the repeat information is correct, the process from step S21 onwards is executed. On the other hand, if the manager requests reconfirmation of the repeat information (presses the reconfirmation button 213b on the child screen 213), the control unit 13 transmits reconfirmation request information requesting reconfirmation to the operator terminal 20 through the communication unit 15 (step S17). In the operator's terminal 20, the control unit 23 acquires the reconfirmation request information through the communication unit 25, and redisplays the instruction information on the display unit 21 (step S18). For example, the control unit 23 displays the child screen 215 of FIG.

[0037] Next, the operator presses the repeat button 215a on the child screen 215. The control unit 23 retransmits the repeat information (for example, information indicating that the repeat button 215a has been pressed) to the manager terminal 10 through the communication unit 25 (step S19). In the manager terminal 10, the control unit 13 acquires the repeat information through the communication unit 15 and displays the repeat information (original instruction information corresponding to the repeat information) on the display unit 11 (step S20). When the manager confirms that the repeat content is correct (when the manager presses the permission button 213a on the child screen 213), the control unit 13 transmits permission information indicating permission to implement the instruction information to the operator terminal 20 through the communication unit 15 (step S21). In the operator terminal 20, the control unit 23 acquires the permission information through the communication unit 25 and displays the permission information on the display unit 21 (step S22). For example, the control unit 23 displays the child screen 214 of FIG. 9.

[0038] The control unit 13 records the history of each transmission and reception in the storage unit 14 when transmitting instruction information (step S13), receiving replay information (steps S15, S19), transmitting reconfirmation request information (step S17), and transmitting permission information (step S21). For example, the control unit 13 records the destination, transmission time, and transmission content for each transmission, and records the sender, reception time, and reception content for each reception. This records the results of three-way communication. By a predetermined operation, the control units 13 and 23 display the history information of three-way communication (transmission and reception time, destination, sender, transmission and reception content) on the display units 11 and 21, respectively. This makes it possible to check the history of three-way communication and check whether the communication was successful by comparing it with the record of the operation actually performed.

[0039] FIG. 14 shows the flow of operations of the manager terminal 10 and the operator terminal 20 when an implementation completion report is made. In the operator's terminal 20, the input reception unit 12 receives the pressing of the completion report button 208. The control unit 23 transmits, through the communication unit 25, the identification information of the operation corresponding to the pressed completion report button 208 and the completion report information indicating that the completion report button 208 has been pressed (step S31). In the manager's terminal 10, the control unit 13 acquires the completion report information through the communication unit 15 and displays the completion report information on the display unit 11 (step S32). For example, the control unit 13 displays the child screen 217 of FIG. 11. When the manager confirms that the operation reported as completed has been correctly performed, the process from step S37 onwards is executed. On the other hand, when the manager requests reconfirmation of the operation content reported as completed (when the manager presses the return button 217b on the child screen 217), the control unit 13 transmits return information for returning the completion report to the operator's terminal 20 through the communication unit 15 (step S33). In the operator's terminal 20, the control unit 23 acquires the send-back information and displays the send-back information on the display unit 21 (step S34). For example, the control unit 23 displays the child screen 219 of FIG.

[0040] The operator reconfirms the operation for which the completion report has been made, and when it is determined that the completion report can be made, the operator presses the completion report button 208 for the operation again. The control unit 23 resends the completion report information (step S35). In the manager terminal 10, the control unit 13 acquires the completion report information through the communication unit 15 and redisplays the completion report information on the display unit 11 (step S36). When the manager confirms that the operation for which the completion report has been made has been correctly executed (when the manager presses the approval button 217a on the child screen 217), the control unit 13 transmits completion approval information indicating that the completion report has been approved to the operator terminal 20 through the communication unit 15 (step S37). The control unit 13 sets the status of the operation for which the completion report has been made to "Complete" (step S38). For example, the control unit 13 records the identification information of the operation for which the completion report has been made, the time when the approval button 217a was pressed, and the status "Complete" in association with each other in the storage unit 14. In the manager terminal 10, the control unit 13 displays the procedure manual with the updated status on the display unit 11 (step S39). In the operator terminal 20, the control unit 13 displays the procedure manual with the updated status on the display unit 21 (step S39').

[0041] The control unit 13 records the history of each transmission and reception in the memory unit 14 when receiving the completion report information (steps S31, S35), sending the return information (step S33), and sending the completion acknowledgement information (step S37). This records the actual communication results when reporting the completion of implementation. By performing a predetermined operation, the control units 13, 23 display the history information of the communication related to the implementation completion report (time of transmission and reception, destination, sender, content of transmission and reception) on the display units 11, 21, respectively. This makes it possible to check the history of the communication related to the implementation completion report and check whether the communication was successful by comparing it with the record of the operation actually performed.

[0042] The process illustrated in FIG. 14 allows the completion of the operation described in the procedure manual to be reliably confirmed. For example, with only verbal confirmation, mistakes such as an operator mistaking that the implementation completion report has been approved or a manager missing the implementation completion report can occur, but such misconceptions can be prevented by displaying the contents of the implementation completion report and the confirmation result for the implementation completion report on the display units 11 and 12. In addition, by updating the status of an operation for which the implementation completion report has been approved, the progress of the operation and procedure described in the procedure manual can be managed. In addition, by displaying the completion of the operation for which the implementation has been completed in the procedure manual, the manager and the operator can grasp the progress of the procedure while referring to the procedure manual display screens 200 and 200'.

[0043] (effect) As described above, according to this embodiment, by issuing and confirming plant operation procedures through communication between terminals, the manager and the operator can visually confirm the instructions and communication contents, eliminating miscommunication and improving communication between the two parties. In addition, it is possible to prevent human errors that tend to occur in verbal communication.
