〔Control System〕

The control system 1 according to this embodiment is a system for controlling at least one device constituting a device. Specific examples of the equipment include steel plant equipment (for example, blast furnace equipment, continuous casting equipment, etc.), water treatment equipment (for example, water supply equipment, water supply equipment, etc.), but not necessarily limited to these. The device may be any device containing a machine that becomes a control object.

As shown in FIG. 1, the control system 1 includes an operation controller 100A, an operation interface device 200A, a server station 300, a reproduction controller 100B, and a reproduction interface device 200B.

The operation controller 100A (control device) controls at least one machine, and generates display data including information related to the operation state of the machine. Specific examples of the information related to the operation state include information indicating the state in size such as position, speed, temperature, etc., and information indicating the state in binary mode such as normal or abnormal. The display data may also include information on operation input (described later) for the operation controller 100A. The operation interface device 200A displays an interface image based on the display data generated by the operation controller 100A. The server station 300 periodically acquires and accumulates data for display from the operation controller 100A. The reproduction controller 100B (control device) is a controller capable of controlling at least one device in the same manner as the operation controller 100A, and sequentially acquires the display materials accumulated in the server station 300. Acquiring the display data sequentially includes: acquiring the display data recorded in the server station 300 in the order of recording time; and acquiring the display data recorded in the server station 300 in the order of reverse recording time. In addition, no matter which order it is in, it also includes every other data or every other data obtained at intervals. The reproduction interface device 200B is a device capable of displaying interface images in the same manner as the operation interface device 200A, and displays interface images based on display materials acquired from the server station 300 by the reproduction controller 100B.

The operation controller 100A is, for example, a programmable logic controller that performs signal input and output with a device that controls an object. Specific examples of the signal include a control command signal output to the device (for example, on/off command signal, speed command signal, etc.), and a feedback signal input from the device (for example, action completion notification signal, abnormality notification) Signals, etc.).

For example, the operation controller 100A has a circuit 110. The circuit 110 has a processor 111, a memory 112, a memory 113, an interface communication port 114, a control input/output port 115, and a recording and reproduction communication port 116. The memory 113 is a non-volatile storage medium (for example, hardware or flash memory) readable by a computer. The memory 113 stores a program that causes the device to perform the following steps: control at least one machine and generate display data including information related to the operation state of the machine. The memory 112 temporarily stores the program downloaded from the memory 113, the calculation result by the processor 111, and the like. The processor 111 executes the above-mentioned program in cooperation with the memory 112, controls at least one machine, and generates display data including information related to the operation state of the machine. The processor 111 may be composed of a plurality of circuit elements.

The interface communication port 114 is connected to the operation interface device 200A via an interface communication path, and performs network communication with the operation interface device 200A according to an instruction from the processor 111. The interface communication path is, for example, a LAN (Local Area Network) for operation monitoring. In addition, the connection here means that information communication is possible, and it does not necessarily mean a wired physical connection. The same is true for the following. That is, the interface communication path may be a wireless communication path.

The control input/output port 115 is connected to at least one machine (for example, a plurality of control object machines 90 (machines) and operating instruments (not shown)) via a high-speed on-site bus, for example, according to instructions from the processor 111 and a plurality of controls Signal input and output are performed between the object machine 90 and the operating equipment.

The recording and reproducing communication port 116 is connected to the server station 300 via a recording and reproducing communication path, and performs network communication with the server station 300 according to an instruction from the processor 111. The recording and reproducing communication path is a communication path different from the interface communication path, and is, for example, a LAN composed of a general-purpose Ethernet (registered trademark). In addition, the fact that the two communication paths are different means that the resources used for communication are independent of each other, and the communication load on one side does not limit the communication volume on the other side. As a specific example of a relationship in which the communication load of one side does not limit the communication volume of the other side, a relationship in which physical resources (for example, cables) used for communication are independent of each other can be cited.

The operation interface device 200A is, for example, an HMI (Human Machine Interface) device for inputting and outputting information with the operation controller 100A, and is connected to the operation controller 100A via an interface communication path. For example, the operation interface device 200A has a main body 201, a display device 202, and an input device 203. The display device 202 is a device for displaying information to a user. As a specific example of the display device 202, a liquid crystal display, an organic EL (Electro-Luminescence) display, etc. are mentioned. The input device 203 is a device for acquiring user input. Specific examples of the input device 203 include a keyboard, a touch panel, and a mouse. In addition, the display device 202 and the input device 203 may be integrated into a so-called touch screen.

The main body 201 has a circuit 210. The circuit 210 has a processor 211, a memory 212, a memory 213, an input/output port 214, and a communication port 215. The memory 213 is a non-volatile storage medium readable by a computer (for example, hardware or flash memory). The memory 213 stores a program that causes the device to perform the following steps: display an interface image based on the display data generated by the operation controller 100A. The memory 212 temporarily stores the program downloaded from the memory 213 and the calculation result by the processor 211 and the like. The processor 211 executes the above-mentioned program in cooperation with the memory 212 to display an interface image based on the display data generated by the operation controller 100A. The processor 211 may be composed of a plurality of circuit elements.

The input/output port 214 performs input and output of information between the display device 202 and the input device 203 according to instructions from the processor 211. The communication port 215 is connected to the interface communication port 114 via an interface communication path, and performs network communication with the operation controller 100A according to an instruction from the processor 211.

In addition, the control system 1 may be provided with a plurality of operation interface devices 200A. In this case, network communication is performed between the interface communication port 114 of the operation controller 100A and the communication ports 215 of the plurality of operation interface devices 200A.

Similar to the operation controller 100A, the playback controller 100B is configured to be able to control at least one device. For example, the reproduction controller 100B is a backup controller that can replace the operation controller 100A when the operation controller 100A fails, and has the same circuit 110 as the operation controller 100A. The memory 113 of the playback controller 100B stores a program that causes the device to perform the following steps: sequentially acquire the display data accumulated in the server station 300. The processor 111 of the playback controller 100B executes the above-mentioned program in cooperation with the memory 112 to sequentially acquire the display data accumulated in the server station 300.

The interface communication port 114 of the reproduction controller 100B is connected to the reproduction interface device 200B via an interface communication path, and performs network communication with the reproduction interface device 200B according to an instruction from the processor 111. The control input/output port 115 of the reproduction controller 100B is connected to a plurality of control object machines 90 and operation instruments (not shown) when the reproduction controller 100B is used instead of the operation controller 100A, and according to the processor 111 Input and output of signals between multiple commands of the object machine 90 and the operating equipment. The recording and reproducing communication port 116 of the reproducing controller 100B is connected to the server station 300 via a recording and reproducing communication path, and performs network communication with the server station 300 according to a request from the processor 111.

Here, the program stored in the memory 113 of the controller 100B for reproduction may be the same as the program stored in the memory 113 of the controller 100A for operation. For example, the memory 113 of the operation controller 100A and the reproduction controller 100B stores a program, and the program causes the device to perform the following operations: control at least one machine; generate an interface diagram based on data obtained in the control of at least one machine Image display data; periodically send the recording data including the display data to the server station 300; sequentially receive the display data accumulated in the server station 300; switch the operation mode and the reproduction mode, the operation mode is based on A mode for generating data for display from data obtained through control of at least one machine, the reproduction mode is a mode for obtaining data for display from the server station 300; and an interface device (for example, an interface device for operation 200A or an interface for reproduction The device 200B) transmits the display material.

According to this formula, by switching the operation mode of the playback controller 100B from the playback mode to the operation mode, the playback controller 100B can be operated as the operation controller 100A. Similarly, by switching the operation mode of the operation controller 100A from the operation mode to the reproduction mode, the operation controller 100A can be operated as the reproduction controller 100B. That is, by simple mode switching, it is possible to switch between the operation controller 100A and the reproduction controller 100B.

The reproduction interface device 200B is a device capable of displaying interface images in the same manner as the operation interface device 200A. For example, the reproduction interface device 200B is a backup HMI device that can replace the operation interface device 200A when the operation interface device 200A fails, and has a main body 201, a display device 202, and an input device 203 like the operation interface device 200A .

The memory 213 of the reproduction interface device 200B stores a program that causes the device to perform the following operation: display an interface image based on display data acquired from the server station 300 by the reproduction controller 100B. In addition, regarding the operation interface device 200A and the reproduction interface device 200B, although it is different from which of the operation controller 100A and the reproduction controller 100B to obtain the display data, an interface diagram based on the display data is displayed Like this point is the same. Therefore, the program stored in the memory 213 of the interface device for reproduction 200B and the program stored in the memory 213 of the interface device for operation 200A may be the same.

The processor 211 of the reproduction interface device 200B executes the above-mentioned program in cooperation with the memory 212 to display an interface image based on the display data acquired from the server station 300 by the reproduction controller 100B. The communication port 215 of the reproduction interface device 200B is connected to the interface communication port 114 of the reproduction controller 100B via an interface communication path, and performs network communication with the reproduction controller 100B according to an instruction from the processor 211.

In addition, the control system 1 may include a plurality of playback interface devices 200B. In this case, the interface communication port 114 of the reproduction controller 100B and the communication ports 215 of the plurality of reproduction interface devices 200B perform network communication. The number of interface devices for reproduction 200B may be less than the number of interface devices for operation 200A.

The server station 300 is, for example, a general-purpose computer such as a personal computer, and is connected to the operation controller 100A and the reproduction controller 100B via a recording and reproduction communication path. For example, the server station 300 has a main body 301, a display device 302, and an input device 303. The display device 302 is a device for displaying information to the user. As a specific example of the display device 302, a liquid crystal display, an organic EL display, or the like can be given. The input device 303 is a device for acquiring user input. As a specific example of the input device 303, a keyboard, a touchpad, a mouse, etc. may be mentioned. In addition, the display device 302 and the input device 303 may be integrated into a so-called touch screen.

The main body 301 has a circuit 310. The circuit 310 has a processor 311, a memory 312, a memory 313, an input/output port 314, a communication port 315, and a communication port 316. The memory 313 is a computer-readable non-volatile storage medium (for example, hardware or flash memory). The memory 313 includes a storage area for storing a program and a storage area for accumulating display data. The program causes the device to perform the following steps: obtain and store the display data from the operation controller 100A.

The memory 312 temporarily stores the program downloaded from the memory 313, the calculation result by the processor 311, and the like. The processor 311 executes the above-mentioned program in cooperation with the memory 312 to acquire display data from the operation controller 100A and accumulate it in the memory 313. The processor 311 may be composed of a plurality of circuit elements. The input/output port 314 performs input and output of information with the display device 302 and the input device 303 according to instructions from the processor 311. The communication port 315 is connected to the above-mentioned recording and reproduction communication port 116 of the operation controller 100A via a recording and reproduction communication path, and performs network communication with the operation controller 100A according to an instruction from the processor 311. The communication port 316 is connected to the above-mentioned recording and reproduction communication port 116 of the reproduction controller 100B via a recording and reproduction communication path, and performs network communication with the reproduction controller 100B according to an instruction from the processor 311.

Hereinafter, the configurations of the operation controller 100A, the reproduction controller 100B, the operation interface device 200A, the reproduction interface device 200B, and the server station 300 will be exemplified in more detail. In the following description, in the description common to the controller 100A for operation and the controller 100B for reproduction, these are referred to as “controller 100” without distinction between them. Similarly, in the descriptions common to the interface device 200A for operation and the interface device 200B for reproduction, these are referred to as “interface device 200” without distinction between these.

FIG. 2 is a block diagram illustrating the functional configuration of the operation controller 100A, the operation interface device 200A, and the server station 300 (hereinafter, referred to as “function module”). FIG. 3 is a block diagram illustrating functional modules of the playback controller 100B, the playback interface device 200B, and the server station 300.

As shown in FIGS. 2 and 3, the controller 100 as a functional module includes a user input acquisition unit 121, a control processing unit 122, a control storage unit 123, a data generation unit 124, an operation change detection unit 125, and a state change The detection unit 126, the reproduction data reception unit 127, the switching unit 128, the interface storage unit 129, the record data transmission unit 131, and the display data transmission unit 132.

The user input acquisition unit 121 receives the user's operation input (for example, the operation input to the display device 202 described above) from the interface device 200. The user input acquisition unit 121 can further acquire user input by the operating device (not shown) from the control input/output port 115 to the controller 100 without going through the interface device 200. The control processing unit 122 controls at least one machine (for example, the above-mentioned plurality of control object machines 90). For example, the control processing unit 122 outputs various control commands such as a movement command to a specified position, a movement command at a specified speed, and the like to the control object machine 90, and obtains from the control object machine 90 the relevant operation state corresponding to the control instruction News. The control processing unit 122 may control the object machine 90 to operate in accordance with the user's input acquired by the user input acquisition unit 121. Hereinafter, the user's input for specifying the control content of the control processing unit 122 is referred to as “operation input to the control processing unit 122 ”.

The control storage unit 123 stores a control program for the control processing unit 122 to execute. The control program includes the content of the control command for controlling the object machine 90 and the output timing of the control command. In addition, the control storage unit 123 acquires the data obtained by the control of the control object machine 90 (hereinafter, referred to as “control data”) from the control processing unit 122 and temporarily stores it. The control data includes information related to the operation state of the control object machine 90 and information related to the operation input to the control processing unit 122. The information related to the operation state of the control object machine 90 may include, for example, information including size such as operation position/speed, and binary information indicating whether it is normal or abnormal (for example, notification of abnormal alarm signal ON/ Disconnect) Both.

The document generating unit 124 generates the display document based on the control document. More specifically, the material generating unit 124 arranges the control materials acquired from the control storage unit 123 in a predetermined format to generate display materials. The document generating unit 124 saves the generated display document to the interface storage unit 129. At this time, the material generating unit 124 may overwrite the old display material (the display material stored in the interface storage unit 129) with the newly stored display material.

The reproduction data receiving unit 127 sequentially receives display materials from the server station 300. The reproduction data receiving unit 127 stores the received display data in the interface storage unit 129. At this time, the reproduction data receiving section 127 may overwrite the old display data (display data stored in the interface storage section 129) with the newly stored display data (refer to FIG. 3).

The interface storage unit 129 is allocated to a predetermined address range in a physical storage area (for example, the storage area of the memory 112). This address range is dedicated to the interface storage unit 129. That is, storage units other than the interface storage unit 129 (for example, the control storage unit 123 described above and the event storage unit 133 described later) are provided in an address range not allocated to the interface storage unit 129.

The display data transmission unit 132 acquires the display data corresponding to the request from the interface device 200 from the interface storage unit 129 and transmits it to the interface device 200.

The switching unit 128 switches the operation mode of acquiring the display material to be transmitted from the material generating unit 124 by the display material transmitting unit 132 and the reproduction mode acquired from the reproduction material receiving unit 127. For example, the switching unit 128 switches the operation mode (refer to FIG. 2) for acquiring the display material to be saved in the interface storage unit 129 from the material generating unit 124 and the playback mode for acquiring the display material from the playback material receiving unit 127 (refer to the 3 picture). When the switching unit 128 sets the operation mode of the controller 100 to the operation mode, the controller 100 can be used as the operation controller 100A. In the operation controller 100A, display data is input from the data generation unit 124 to the interface storage unit 129 via the switching unit 128 (refer to FIG. 2 ).

Once the switching unit 128 sets the operation mode of the controller 100 to the playback mode, the controller 100 can be used as the playback controller 100B. In the reproduction controller 100B, the display material is input from the reproduction material receiving unit 127 to the interface storage unit 129 via the switching unit 128 (see FIG. 3 ).

The operation change detection unit 125 detects the changed information as the operation history information when the change in the content of the operation input to the control processing unit 122 satisfies the preset detection condition. For example, the operation change detection unit 125 refers to the control data stored in the control storage unit 123 to detect the operation history information described above, and stores the detected operation history information in the event storage unit 133. The operation history information includes, for example, the time when a change that satisfies the above-mentioned detection conditions and the content of the change. As a specific example of the above detection condition, "the change amount of the operation input exceeds zero" may be mentioned. When such a condition is set, all the changed information generated in the operation input content is detected as operation history information.

The state change detection unit 126 detects the change information as state history information and stores it in the event storage unit 133 when the change in the state of the control object machine 90 satisfies the preset detection conditions. For example, the state change detection unit 126 refers to the control data stored in the control storage unit 123 to detect the above state history information, and saves the detected state history information in the event storage unit 133. The state history information includes, for example, the time when a change that satisfies the above-mentioned detection conditions and the content of the change. As a specific example of the above detection conditions, the following may be mentioned: the machine alarm signal changes from the off state to the on state, the alarm signal notifies the occurrence of abnormality of the control object machine 90; and the state indicating the operation state of the control object machine 90 The value changes from normal value to abnormal value.

The log data transmission unit 131 periodically sends log materials to the server station 300, and the log materials include the display data generated by the data generation unit 124. The log data transmission unit 131 may periodically transmit log data including the above-mentioned operation history information to the server station 300, or may periodically transmit log data including the above-mentioned state history information to the server station 300. The log data transmission unit 131 obtains the display data included in the log data from the interface storage unit 129, and the operation history information and state history information included in the log data from the event storage unit 133. In addition, the period in which the record data transmitting section 131 transmits the record data may be longer than the period in which the display data transmitting section 132 transmits the display data.

Each functional module of the controller 100 is configured by, for example, the processor 111 and the memory 112 cooperatively execute the program of the memory 113. The controller 100 is not limited to a controller that must be constituted by a program. At least a part of the functional modules of the controller 100, for example, functional modules for controlling communication, may be constituted by a dedicated logic circuit or an ASIC (Application Specific Integrated Circuit) integrated with it.

The interface device 200 has a display unit 222 and a user input acquisition unit 221 as a function module. The display unit 222 periodically receives display data for displaying an interface image preset as a display object from the display data transmission unit 132, and displays the interface image based on the received display data. The interface image includes, for example, an image indicating the operation state of the control object machine 90 based on the above-mentioned display data, and a tool image for user input.

For example, the log data accumulation unit 322 sequentially accumulates time information such as the reception time of the log data received by the log data reception unit 321 and the content of the log data in a corresponding manner. The recorded data storage unit 322 may store the accumulated data into a file (hereinafter, referred to as a "data file") every predetermined time. In addition, the log data storage unit 322 can automatically delete old files in accordance with the reduction in the free space in the storage area.

The log display unit 325 displays at least one of status history information and operation history information in accordance with the input to the operation mode setting unit 324. For example, the log display unit 325 displays at least one of status history information and operation history information in a chronological table or graph.

The data extracting unit 326 extracts the display data sent from the playback data transmitting unit 323 to the playback data receiving unit 127, the status history information displayed by the log display unit 325, and the operation history information displayed by the log display unit 325 from the log data storage unit 322. For example, the data extraction unit 326 performs the following operations according to user input (for example, input to the input device 303): reads the data file from the recorded data storage unit 322; extracts the state history information and operation history information in the data file And output to the log display unit 325; and sequentially extract the display data in the data file and output to the reproduction data transmission unit 323.

The operation mode setting unit 324 obtains a user's input and outputs it to the switching unit 128 of the controller 100, and the user's input specifies the operation mode of the controller 100 (the above-mentioned operation mode or reproduction mode).

[Recording/reproduction program of control data]

Next, as an example of a recording/reproduction method of control data, a recording/reproduction program executed by the control system 1 will be exemplified. In the following, the program is divided into a preset program, a recording program for display data, and a reproduction program for display data for detailed description.

(Program in advance)

FIG. 4 is a flowchart showing a procedure for the server station 300 to acquire the operation mode designation of the controller 100. As shown in FIG. 4, the server station 300 executes steps S01, S02, S03, and S04. In step S01, the operation mode setting unit 324 waits for the call of the designated function of the operation mode (for example, the start of the application for specifying the operation mode). In step S02, the operation mode setting unit 324 displays a screen for specifying the operation mode (for example, on the display device 302). In step S03, the operation mode setting unit 324 waits for the user's input to the screen for specifying the operation mode. In step S04, the operation mode setting unit 324 obtains input to the screen for specifying the operation mode, and outputs it to the switching unit 128 of the controller 100. The switching unit 128 sets the operation mode of the controller 100 to any of the above-described operation mode or playback mode in accordance with the designation of the operation mode. The controller 100 whose operation mode is set to the operation mode in step S04 can be used as the operation controller 100A, and the interface device 200 connected to the controller 100 functions as the operation interface device 200A. On the other hand, the controller 100 whose operation mode is set to the playback mode in step S04 can be used as the playback controller 100B, and the interface device 200 connected to the controller 100 functions as the playback interface device 200B. The above completes the setting mode of the operation mode.

(Recording program for display data)

FIG. 5 is a flowchart illustrating a recording program of display data executed by the operation controller 100A. As shown in FIG. 5, the operation controller 100A first executes steps S31 and S32. In step S31, the control processing part 122 acquires the operation input information from the user input acquisition part 121, and the operation input information is the information acquired from the user input acquisition part 221 or the like. In step S32, the operation change detection unit 125 confirms whether the change in the operation input (the change in the operation input acquired from the previous time) satisfies the predetermined detection condition.

When it is determined in step S32 that the change in the operation input satisfies the detection condition, the operation controller 100A executes step S33. In step S33, the operation change detection unit 125 detects the change information of the operation input as the operation history information, and saves the operation history information to the event storage unit 133.

Next, the operation controller 100A executes step S34. When it is determined in step S32 that the change in the operation input does not satisfy the detection condition, the operation controller 100A omits step S33 and executes step S34. In step S34, the control processing unit 122 acquires information related to the operation state from the control object machine 90.

Next, the operation controller 100A executes step S35. In step S35, the control processing unit 122 confirms whether the change in the operation state (the change in the operation state acquired from the previous time) satisfies a predetermined detection condition.

When it is determined in step S35 that the change in the operation state satisfies the detection condition, the operation controller 100A executes step S36. In step S36, the state change detection unit 126 detects the change information of the operation state as state history information, and saves the state history information to the event storage unit 133.

Next, the operation controller 100A executes step S37. When it is determined in step S35 that the change in the middle operation state does not satisfy the detection condition, the operation controller 100A omits step S36 and executes step S37. In step S37, the control processing unit 122 outputs a control command to the control object machine 90 based on the control program, operation input, and operation state stored in the control storage unit 123. For example, the control processing unit 122 calculates a control command for bringing the operation state closer to the state according to the control program and operation input, and outputs it to the control object machine 90. The control processing unit 122 stores the above-mentioned control data obtained by controlling the object machine 90 in the control processing unit 122.

Next, the operation controller 100A executes steps S38, S41, and S42. In step S38, the document generating unit 124 generates the display document based on the control document and stores it in the interface storage unit 129. In step S41, the control processing unit 122 waits for the control cycle to elapse. In step S42, the recorded material transmitting unit 131 confirms whether a cycle for transmitting the recorded material (hereinafter, referred to as "recording cycle") has passed.

When it is determined in step S42 that the recording cycle has elapsed, the operation controller 100A executes step S43. In step S43, the log data transmission unit 131 sends the log data including the display data stored in the interface storage unit 129 and the operation history information and status history information stored in the event storage unit 133 to the log data reception unit 321 And delete the stored content of the event storage unit 133.

Thereafter, the operation controller 100A returns the process to step S31. When it is determined in step S42 that the recording cycle has not passed, the operation controller 100A returns to step S31 without performing step S43. Thereafter, the control by the control processing unit 122 is repeated in the control cycle, and the transmission of the recording data toward the server station 300 is repeated in the recording cycle.

FIG. 6 is a flowchart illustrating a display program of display data executed by the operation interface device 200A. As shown in FIG. 6, the operation interface device 200A executes steps S51, S52, and S53. In step S51, the display unit 222 acquires data for displaying the interface image preset as the display object from the display data transmission unit 132. For example, the display unit 222 specifies the identification information of the data for displaying the interface image, and obtains the data extracted by the display data transmission unit 132 from the display data of the interface storage unit 129 according to the identification information. In step S52, the display unit 222 displays the updated interface image based on the received display data. In step S53, the display unit 222 waits for a preset display update cycle to pass. Thereafter, the operation interface device 200A returns the process to step S51. After that, the acquisition of display materials and the update of interface images are repeated in a display update cycle.

FIG. 7 is a flowchart illustrating an accumulation program of recorded data executed by the server station 300. As shown in FIG. 7, the server station 300 first executes steps S61 and S62. In step S61, the log data receiving unit 321 waits for the log data to be received. In step S62, the log material receiving unit 321 receives the log material transmitted by the log material transmitting unit 131 and accumulates it. For example, the recorded data receiving unit 321 associates the time information such as the received time of the recorded data and the content of the recorded data in a temporary storage area (for example, the storage area of the memory 312) and accumulates the data file.

Next, the server station 300 executes step S63. In step S63, the recorded data receiving section 321 confirms whether the amount of recorded data accumulated in the data file reaches a predetermined amount (for example, the amount of data for one hour). In step S63, when it is determined that the number of recorded materials does not reach the predetermined number, the server station 300 returns the process to step S61. After that, the reception and accumulation of recorded data are repeated until the number of recorded data accumulated in the data file reaches a predetermined amount. In step S63, if it is determined that the number of recorded data reaches a predetermined number, the server station 300 executes step S64. In step S64, the recorded data receiving unit 321 saves the data file to the recorded data storage unit 322. The record data receiving unit 321 may add a file name including the save date and time to save the data file.

Next, the server station 300 executes step S65. In step S65, the log data storage unit 322 confirms whether the remaining capacity (for example, the capacity of an area in the storage area allocated to the log data storage unit 322 where no data file is stored) is smaller than a preset file deletion criterion value. In step S65, when it is determined that the remaining capacity is equal to or greater than the file deletion reference value, the server station 300 returns the process to step S61. Thereafter, the accumulation of recorded data and the storage of data files are repeated until the remaining capacity is less than the file deletion reference value. In step S65, when it is determined that the remaining capacity is less than the file deletion reference value, the recorded data storage unit 322 deletes the oldest data file. The log data storage unit 322 may delete a plurality of files in order from the oldest side. The server station 300 repeatedly executes the above accumulation program.

(Reproduction program for display data)

FIG. 8 is a flowchart illustrating a reproduction program of the display data executed by the server station 300. In addition, the reproduction here means that the display materials accumulated in the recording material storage unit 322 are sequentially transmitted to the reproduction controller 100B. The playback controller 100B sequentially acquires the display materials transmitted from the server station 300, and the playback interface device 200B displays an interface image based on the display materials acquired by the playback controller 100B.

First, the server station 300 executes steps S71 and S72. In step S71, the material extraction unit 326 waits for the call of the playback operation function (for example, the start of the application for the playback operation). In step S72, the material extraction unit 326 displays a screen for playback operation (for example, display on the display device 302).

Next, the server station 300 executes steps S73, S74, S75, and S76. In step S73, the data extraction unit 326 waits for a download (read from memory 313) instruction of the data file. For example, the material extraction unit 326 waits for the download button of the material file on the playback operation screen to be operated (for example, click or tap). In step S74, the data extraction unit 326 displays a screen for selecting a data file. In step S75, the data extraction unit 326 waits for the selection input of the data file on the selection screen. On the screen for selecting a data file, the operator of the server station 300 selects the data file of the time zone to be reproduced based on the date and time information included in the file name. In step S76, the data extraction unit 326 downloads the selected data file. Hereinafter, the downloaded data file is referred to as "reproduction destination file".

Next, the server station 300 executes step S77. In step S77, the data extraction unit 326 confirms whether an operation history search command (command to search for operation history information in the reproduction destination file) is input. For example, the material extraction unit 326 confirms whether the operation history search button is operated (for example, click or tap) on the playback operation screen. In step S77, when it is determined that the operation history search command is input, the server station 300 executes step S78. In step S78, the data extraction unit 326 extracts the operation history information in the reproduction destination file and outputs it to the log display unit 325. Correspondingly, the log display unit 325 displays the extracted operation history information list on the playback operation screen. In addition, the list display may include display of identification information (for example, frame number) of display data corresponding to each operation history information.

In step S77, when it is determined that the operation history search instruction has not been input, the server station 300 executes step S81. In step S81, the data extraction unit 326 confirms whether a state history search command (command to search for state history information in the reproduction destination file) is input. For example, the material extraction unit 326 confirms whether or not the state history search button is operated (for example, click or tap) on the above-mentioned playback operation screen. In step S81, when it is determined that the state history search command is input, the server station 300 executes step S82. In step S82, the data extraction unit 326 extracts the state history information in the reproduction destination file and outputs it to the log display unit 325. Correspondingly, the log display unit 325 displays the extracted state history information in a list on the playback operation screen. In addition, the list display may include display of identification information (for example, frame number) of display data corresponding to each state history information.

After step S78 or step S82, the server station 300 executes step S83. When it is determined in step S81 that the state history search command has not been input, the server station 300 executes step S83 without executing steps S78 and S82. In step S83, the material extraction unit 326 confirms whether a reproduction start instruction is input. For example, the material extraction unit 326 confirms whether the input button of the playback instruction on the playback operation screen is operated (for example, click or tap). In step S83, when it is determined that the reproduction start instruction has not been input, the server station 300 returns the process to step S77. After that, the waiting of the operation history retrieval instruction and the state history retrieval instruction, and the extraction/display of the operation history information and the state history information corresponding to the instruction are repeated until the reproduction start instruction is input.

In addition, the above-mentioned reproduction operation screen may include input buttons for various reproduction instructions. As a specific example of the input button, a forward reproduction button that displays the display material in the order of the old recording time, a reverse reproduction button that reproduces the display material in the order of the new recording time, and the like can be mentioned. Furthermore, the reproduction operation screen may further include a tool for specifying reproduction conditions. As a specific example of a tool for specifying playback conditions, a start frame input box for inputting identification information of display data for starting playback can be cited, and the transfer of the display data for playback objects is accelerated toward the new side of the recording time A fast forward button, a rewind button that accelerates the transfer of the display material of the reproduction object toward the side where the recording time is old, and so on.

When it is determined in step S83 that the reproduction start command is input, the server station 300 executes step S91 as shown in FIG. 9. In step S91, the material extraction unit 326 sets the playback conditions based on the input content to the playback operation screen. For example, the material extraction unit 326 determines whether to perform forward reproduction (reproduction of the display material in the order of the old recording time) or reverse reproduction (reproduction and display in the order of the new recording time) based on which of the forward playback button and the reverse playback button is operated Use information). In addition, the material extraction unit 326 may determine the display material to start reproduction based on the input to the start frame input frame or the like.

Next, the server station 300 executes steps S92 and S93. In step S92, the material extraction unit 326 extracts the next display material to be reproduced (hereinafter, referred to as "reproduction material") from the material file based on the reproduction conditions, and outputs it to the reproduction material transmission unit 323. In step S93, the reproduction material transmitting unit 323 outputs the reproduction material to the reproduction material receiving unit 127 of the reproduction controller 100B. Corresponding to this, the reproduction data receiving unit 127 writes the reproduction data to the interface storage unit 129. When the reproduction material is written to the interface storage unit 129, the interface image based on the reproduction material is displayed by the reproduction interface device 200B. In addition, the processing performed by the interface device 200B for reproduction for displaying the interface image is the same as the above-described steps S51, S52, and S53 performed by the interface device 200A for operation.

Next, the server station 300 executes step S94. In step S94, the material extraction unit 326 confirms whether or not a change condition reproduction command has not been input. As a specific example of the change condition of the reproduction condition, a reverse direction instruction of the reproduction direction by the operation of the forward reproduction button or the reverse reproduction button, and a reproduction acceleration instruction by the operation of the fast forward button or the backward button can be mentioned. Wait. As another specific example, a combination of the input of the identification information for the start frame input frame and the operation of the forward playback button or the reverse playback button may be used to jump the playback position to the display corresponding to the identification information. Information instructions.

In step S94, when it is determined that there is an instruction to change the reproduction condition, the server station 300 returns the process to step S91, and after performing the setting of the reproduction condition again, extraction/transmission of the display material is restarted. In step S94, when it is determined that there is no instruction to change the reproduction condition, the server station 300 executes step S95. In step S95, the material extraction unit 326 confirms whether a reproduction stop command is input. For example, the material extraction unit 326 confirms whether the input button of the stop command is operated (for example, click or tap) on the above-mentioned playback operation screen.

In step S95, when it is determined that there is no stop command, the server station 300 executes step S96. In step S96, the material extraction unit 326 confirms whether a predetermined reproduction frame period has passed. For example, the material extraction unit 326 confirms whether the elapsed time from the imminent start step S92 has reached the aforementioned reproduction frame period. When it is determined in step S96 that the reproduction frame period has not passed, the server station 300 returns the process to step S94. After that, the presence or absence of the reproduction condition change command and the stop command is continued until the reproduction frame period elapses.

In step S96, when it is determined that the reproduction frame period has elapsed, the server station 300 executes step S97. In step S97, the material extraction unit 326 transfers the frame of the reproduction object (identification information of the display material) to the next frame according to the reproduction conditions. When the reproduction acceleration command is input as a reproduction condition change command, the material extraction unit 326 may transfer the frame of the reproduction object to a frame skipping one or more frames. That is, the document extraction unit 326 may extract the document for display with one document or a plurality of documents. Thus, reproduction is accelerated. In addition, instead of extracting the data for display, it is possible to speed up the reproduction by shortening the reproduction frame period. After the execution of step S97, the server station 300 returns the process to step S92. From now on, as long as there is no input of the change condition of the reproduction condition or the stop instruction, the reproduction according to the reproduction condition is continued.

In step S95, if it is determined that there is a stop command, the server station 300 ends the playback routine. In addition, the server station 300 when the display data of the reproduction object reaches the end of the reproduction destination file (in the case of forward reproduction: the display data with the latest recording time, and in the reverse reproduction: the display data with the oldest recording time) , You can end the playback program, or you can return to the beginning of the playback destination file (sequential playback: the oldest recording data for display time, reverse playback: the latest recording time for display data) and continue playback.

[Effects of this embodiment]

As described above, the control system 1 includes: an operation controller 100A that controls at least one machine and generates display data including information related to the operation state of the machine; an operation interface device 200A whose display is based on The interface image of the display data generated by the operation controller 100A; the server station 300, which obtains and stores the display data from the operation controller 100A; and the reproduction controller 100B, which is the same as the operation controller 100A Similarly, the controller 100 capable of controlling at least one machine and sequentially acquiring the display data accumulated in the server station 300; and the reproduction interface device 200B, which can display interface images in the same manner as the operation interface device 200A The device also displays an interface image based on the display material acquired from the server station 300 by the reproduction controller 100B.

According to this control system, the same situation as the following situation is reproduced between the reproduction controller 100B and the reproduction interface device 200B: the interface diagram based on the display data generated by the operation controller 100A is displayed on the operation interface device 200A Like. Therefore, by reproducing the previous interface image in the same manner as the display of the interface image by the operation interface device 200A, it is possible to easily verify the operation history. Specifically, since the display data in the same manner as the display data generated by the operation controller 100A is reproduced in the playback controller 100B, any interface image can be used as long as it is based on the display data Afterwards, it is displayed on the playback interface device 200B. Therefore, even an interface image that is not displayed by the operation interface device 200A can be reproduced afterwards in the reproduction interface device 200B.

In addition, the controller 100B for reproduction is configured by the controller 100 capable of controlling the device in the same manner as the controller 100A for operation, and therefore the controller 100B for reproduction can be effectively used as a backup for the controller 100A for operation. In other words, it is possible to effectively use the standby of the operation controller 100A as the reproduction controller 100B.

Similarly, since the reproduction interface device 200B is configured by a device that can display interface images in the same manner as the operation interface device 200A, the reproduction interface device 200B can be effectively used as a backup for the operation interface device 200A. In other words, the backup of the operation interface device 200A can be effectively used as the reproduction interface device 200B.

Furthermore, the configuration of the interface device 200A for operation and the interface device 200B for reproduction can be made common. Therefore, it is possible to easily convert between them. In addition, in the interface device 200A for operation and the interface device 200B for reproduction, the software can be generalized. Therefore, it is easy to update the software. This enables effective management/operation of the system.

The operation interface device 200A and the reproduction interface device 200B are respectively connected to the operation controller 100A and the reproduction controller 100B via an interface communication path, and the server station 300 can communicate with the operation via a recording and reproduction communication path different from the interface communication path The controller 100A and the reproduction controller 100B are connected. In this case, even if the transmission frequency of data from the operation controller 100A to the server station 300 and the transmission frequency of data from the server station 300 to the reproduction controller 100B increase, the communication load of the interface communication path will not be increase. Therefore, it is possible to shorten the period for accumulating display data in the server station 300. This makes it possible to verify the operation history in more detail.

Each of the operation controller 100A and the reproduction controller 100B includes: a control processing unit 122 that controls at least one control object machine 90; and a data generation unit 124 that is based on at least one control object machine performed by the control processing unit 122 The data obtained by the control of 90 is used to generate the display data; the record data transmitting unit 131 periodically sends the recording data including the display data generated by the data generating unit 124 to the server station 300; the reproduction data receiving unit 127, which sequentially receives the display data from the server station 300; the display data transmission unit 132, which transmits the display data to the operation interface device 200A or the reproduction interface device 200B; and the switching unit 128, which switches from the data generation unit 124 The operation mode for acquiring the display material to be transmitted by the display material transmission unit 132 and the reproduction mode for acquiring the display material from the reproduction material receiving unit 127. In this case, while the operation controller 100A and the reproduction controller 100B are made common in configuration, by only switching the operation mode and the reproduction mode by the switching unit 128, it is possible to easily transfer between them. The software for the controller 100A for operation and the controller for reproduction 100B can be generalized. Therefore, it is easy to update the software. Thereby, effective management/operation of the system can be performed.

Each of the operation controller 100A and the reproduction controller 100B may further include a state change detection unit 126 which, when the state change of the control object machine 90 satisfies the preset detection conditions, will The changed information is detected as state history information, and the record data sending unit 131 may periodically send the record data including the state history information to the server station 300. In this case, referring to the state history information, the past interface image can be reproduced within the range that should be verified. Therefore, the operation history can be more easily verified.

Each of the operation interface device 200A and the reproduction interface device 200B has a display unit 222 that displays an interface image, a user input acquisition unit 221 that obtains an operation input to the control processing unit 122, an operation controller 100A, and a reproduction Each of the controllers 100B further includes an operation change detection unit 125 that detects the changed information as operation history information when the change in the content of the operation input satisfies the preset detection conditions. The log data transmission unit 131 may periodically transmit log data including operation history information to the server station 300. In this case, referring to the operation history information, it is possible to limit the range to be verified and reproduce the past interface image. Therefore, the operation history can be more easily verified.

Each of the operation controller 100A and the reproduction controller 100B further includes an interface storage unit 129 which is allocated to a predetermined address range in a physical storage area, and the data generation unit 124 generates the The display data is saved in the interface storage unit 129, the record data transmission unit 131 acquires the display data to be included in the record data transmitted to the server station 300 from the interface storage unit 129, and the reproduction data reception unit 127 converts the received display The data is saved in the interface storage unit 129, and the display data transmission unit 132 can obtain the display data transmitted from the interface storage unit 129 to the operation interface device 200A or the reproduction interface device 200B. In this case, by fixing the address range for storing the data for display, writing and reading of the data for display can be speeded up. Thereby, the period for accumulating the display data in the server station 300 can be further shortened.

In addition, according to the configuration of acquiring the data for displaying the interface image from a specific storage area, even when the control object device 90 is changed or added, the search range of the display data does not change, so there is no need to The program of the interface between the controller 100 and the interface device 200 is changed. Therefore, further effective management/operation of the system can be performed.
