That is, the positional relationship is information indicating what operation the operation unit 25 performs when remote input data having a predetermined content is input. The positional relationship storage unit 44 stores the positional relationship. This positional relationship is preset and stored before actually performing a remote operation. That is, the calibration unit 42 calibrates the operation of the operation unit 25 with respect to the remote input data. In the present embodiment, the positional relationship is a relationship between keyboard remote input data that is input to the remote keyboard 16 and the position to which the keyboard actuator unit 76 is moved. In other words, it can be said that the positional relationship is positional information in the input area 106 </ b> A of the same key 106 </ b> B as the key input to the remote keyboard 16.

  FIG. 8 is a flowchart illustrating a positional relationship setting method by the calibration unit. When performing calibration, first, the operator performs a predetermined input to the remote input unit 15. Here, the operator presses a predetermined key of the remote keyboard 16. The remote input data acquisition unit 30 detects the contents of the input, that is, which key is pressed, and acquires information (character information) assigned to the key as keyboard remote input data. The calibration part 42 acquires this keyboard remote input data via the communication part 40 (step S10). In other words, the calibration unit 42 acquires information indicating which character has been input as keyboard remote input data. After acquiring the keyboard remote input data, the calibration unit 42 selects the keyboard actuator unit 76 to be moved (step S12). That is, the calibration unit 42 selects one keyboard actuator unit 76 to be moved among the keyboard actuator units 76 provided in each keyboard rail unit 74. The calibration unit 42 stores in advance temporary information indicating which keyboard actuator unit 76 is to be moved for each input character, and selects the keyboard actuator unit 76 to be moved based on the temporary information. Moreover, you may select the keyboard actuator part 76 which an operator moves.

  After determining the actuator unit to be moved, the calibration unit 42 moves the rail moving unit 75 and the keyboard rail moving unit 77 corresponding to the keyboard actuator unit 76 (step S14), and the selected keyboard actuator unit 76 is moved. Move to a predetermined position set in advance. The predetermined position may be stored in advance by the calibration unit 42 for each input character, or may be set each time by the operator.

  After moving the rail moving part 75 and the keyboard rail moving part 77, the calibration part 42 protrudes the protruding part 78 of the selected keyboard actuator part 76 (step S16), and the protruding part 78 moves in the direction Z. The key 106B immediately below is pressed. The character information of the pressed key 106B is displayed on the display unit 104 and captured by the display unit imaging unit 24. The image captured by the display image capturing unit 24 is displayed on the remote display unit 14 by the remote display control unit 34. The operator visually recognizes the display, confirms that the key input by the operator and the key input by the protruding portion 78 are the same character information, and inputs the information to that effect to the remote input unit 15 for calibration. To the communication unit 42. Note that an image of the input area 106 </ b> A of the keyboard 106 captured by the imaging unit C may be displayed instead of the image captured by the display unit imaging unit 24. Even in this image, it is possible to confirm which key 106B the protruding portion 78 has pressed.

  The calibration unit 42 determines whether information indicating the same character information has been acquired (step S17). When the calibration unit 42 acquires information indicating that the character information is the same (step S17; Yes), the selected keyboard actuator unit 76, its predetermined position, and keyboard remote input data (character information) The positional relationship is stored in the positional relationship storage unit 44 (step S18). When the calibration unit 42 has not acquired information indicating that the character information is the same (step S17; No), that is, the key that the operator inputs is the same as the key that the protrusion 78 has input. If it is determined that the information is not character information, the process returns to step S12, and the same process is repeated by changing the selected keyboard actuator unit 76 or changing a predetermined position at which the keyboard actuator unit 76 moves.

  After step S18, the process moves to step S19, and the calibration unit 42 determines whether all calibrations are completed, that is, whether the positional relationship is stored for all keys in the remote keyboard 16, and all calibrations are performed. When the calibration is not completed (step S19; No), the process returns to step S10, and the positional relationship is set for the input made by the operator with respect to other keys. When all the calibrations are completed (step S19; Yes), the calibration process is completed.

  In this way, the calibration unit 42 sets the relationship (positional relationship) with respect to the character information input to the remote keyboard 16 with respect to the moving position of the keyboard actuator unit 76 for all character information in the remote keyboard 16. It is stored in the positional relationship storage unit 44. It should be noted that the calibration unit 42 also previously stores the positional relationship between the moving direction and moving amount of the remote mouse 18 as the mouse remote input data and the moving position of the mouse actuator unit 86 (the moving destination position of the mouse 108). It may be set.

  The positional relationship can be updated and set by the calibration unit 42 even after the remote operation is started. For example, the operator needs to update the positional relationship by visually recognizing the captured image of the display unit imaging unit 24 displayed on the remote display unit 14 and the image of the input area 106A of the keyboard 106 captured by the imaging unit C. If it is determined, the calibration unit 42 is started up and the positional relationship is updated (calibration).

  Returning to FIG. 7, the input position determination unit 46 operates after performing a remote operation after the positional relationship is set by the calibration unit 42. The input position determination unit 46 acquires remote input data from the communication unit 40 when performing a remote operation, and determines the movement position of the operation unit 25. In other words, the input position determining unit 46 determines to which position in the input area 106A the operating unit 25 performs input. Specifically, the input position determination unit 46 includes a keyboard input position determination unit 52 and a mouse input position determination unit 54.

  The keyboard input position determination unit 52 acquires keyboard remote input data from the communication unit 40. Then, the keyboard input position determination unit 52 reads the positional relationship from the positional relationship storage unit 44 and selects the keyboard actuator unit 76 corresponding to the acquired keyboard remote input data. Then, the keyboard input position determination unit 52 determines a position to move the keyboard actuator unit 76 corresponding to the acquired keyboard remote input data, that is, a movement destination position.

  The mouse input position determination unit 54 acquires mouse remote input data from the communication unit 40. When the mouse remote input data is information for moving the remote mouse 18, that is, the movement direction and movement amount of the remote mouse 18, the mouse input position determination unit 54 has the same mouse movement position and movement amount as the mouse actuator. The moving direction and moving amount of the part 86 are determined. When the mouse remote input data is information for pressing a button of the remote mouse 18, the mouse input position determination unit 54 selects a button input operation unit 88 to be projected from among the plurality of button input operation units 88.

  The actuator control unit 48 controls the operation unit 25 so as to input the position determined by the input position determination unit 46. The actuator control unit 48 includes a keyboard actuator control unit 56 and a mouse actuator control unit 58.

  The keyboard actuator control unit 56 moves the keyboard actuator unit 76 selected by the keyboard input position determining unit 52 to a destination position that is the position determined by the keyboard input position determining unit 52. Specifically, the keyboard actuator control unit 56 moves the rail moving unit 75 and the keyboard rail moving unit 77 to move the keyboard actuator unit 76 to the movement destination position. For example, when the keyboard actuator unit 76A provided in the keyboard rail unit 74A in FIG. 3 is selected, the keyboard actuator control unit 56 moves the rail moving unit 75 provided in the keyboard rail unit 74A and moves the keyboard actuator unit 76A to the keyboard actuator unit 76A. The provided keyboard rail moving part 77 is moved. The keyboard actuator controller 56 causes the protrusion 78 of the keyboard actuator 76 that has moved to the destination position to protrude. Thereby, the protrusion 78 presses the key 106B arranged at the movement destination position, that is, the same key 106B as the key in the remote keyboard 16 input by the operator.

  The mouse actuator control unit 58 moves the mouse actuator unit 86 by the determined movement amount in the movement direction determined by the mouse input position determination unit 54. Specifically, the mouse actuator control unit 58 moves the mouse actuator unit 86 by moving the mouse first moving unit 85 and the mouse second moving unit 87. As a result, the mouse actuator unit 86 moves the mouse 108 in the same direction and amount as the operator moved the remote mouse 18. Further, the mouse actuator control unit 58 causes the button input operation unit 88 selected by the mouse input position determination unit 54 to protrude. Accordingly, the mouse actuator unit 86 presses the same button 108A as the button pressed by the operator. In addition, when the bottom surface of the remote mouse 18 is separated from the contact surface, the mouse actuator control unit 58 retracts the protruding portion 90 of the mouse fixing unit 89 in the direction Z and separates the bottom surface of the mouse 108 from the moving region G. .

  Hereinafter, a control flow for remotely operating the keyboard 106 will be described with reference to flowcharts. FIG. 9 is a flowchart illustrating a control flow for remotely operating the keyboard. When the keyboard 106 is remotely operated, first, an operator performs physical input, that is, pressing of a key to the remote keyboard 16. The remote control unit 12 detects the press by the remote input data acquisition unit 30, acquires the character information of the pressed key as keyboard remote input data, and transmits it to the input control unit 22 by the communication unit 32. (Step S20).

  After acquiring the keyboard remote input data, the input control unit 22 uses the keyboard input position determination unit 52 to select the keyboard actuator unit 76 to be moved based on the keyboard remote input data and the positional relationship. A destination position is determined (step S22). After selecting the keyboard actuator unit 76 and determining the movement destination position, the input control unit 22 causes the keyboard actuator control unit 56 to move the selected keyboard actuator unit 76 to the movement destination position (step S24). Specifically, the keyboard actuator control unit 56 moves the rail moving unit 75 of the keyboard rail unit 74 to which the selected keyboard actuator unit 76 is attached, and the keyboard rail moving unit 77 provided in the selected keyboard actuator unit 76. Move. As shown in FIG. 3, the keyboard rail portion 74 may be previously arranged above each key group 107, that is, on the direction Z side by the calibration portion 42. In the example of FIG. 3, the keyboard rail portion 74A is disposed on the direction Z side of the key group 107A, and the keyboard rail portion 74B is disposed on the direction Z side of the key group 107B. The other keyboard rails 74 are also arranged on the direction Z side of the key group 107 in the same manner. That is, the calibration unit 42 may assign the keyboard rail unit 74 to any one of the key groups 107 in advance. Thus, by assigning in advance, it is not necessary to move the keyboard actuator unit 76, that is, the rail moving unit 75 in the direction Y each time.

  After moving the selected keyboard actuator unit 76 to the movement destination position, the input control unit 22 causes the keyboard actuator control unit 56 to project the projection 78 of the keyboard actuator unit 76 (step S26), and the movement destination. Press the key 106B at the position. Thereby, this process is completed. Since the movement destination position is a position determined in advance by calibration, the key 106B pressed by the protruding portion 78 has the same character information as the key pressed by the operator on the remote keyboard 16. Therefore, the operator can remotely operate the keyboard 106 by pressing the remote keyboard 16.

  The keyboard remote input data is generated every time the operator presses one key, and the keyboard actuator unit 76 presses the key 106B each time. The keyboard input position determination unit 52 predicts the character information in the next keyboard remote input data from the character information of the keyboard remote input data, and predicts the keyboard actuator unit 76 different from the selected keyboard actuator unit 76. It may be moved toward the key 106B having the next character information.

  Next, a control flow for remotely operating the mouse 108, more specifically, a control flow for moving the mouse 108 by remote operation will be described with reference to a flowchart. FIG. 10 is a flowchart illustrating a control flow for remotely operating a mouse. More specifically, FIG. 10 is a flowchart illustrating a control flow for moving the mouse 108 by remote operation. When moving the mouse 108 by remote operation, first, the operator moves a physical input to the remote mouse 18, that is, moves the remote mouse 18. The remote control unit 12 detects the movement direction and movement amount of the remote mouse 18 by the remote input data acquisition unit 30, acquires information on the movement direction and movement amount as mouse remote input data, and the communication unit 32. It transmits to the input control part 22 (step S30).

  After acquiring the mouse remote input data, the input control unit 22 causes the mouse input position determination unit 54 to have the same movement direction and movement amount as the remote mouse 18 based on the mouse remote input data. The moving direction and moving amount are determined (step S32). After determining the movement direction and movement amount of the mouse actuator unit 86, the input control unit 22 causes the mouse actuator control unit 58 to move the mouse actuator unit 86 by the determined movement amount in the determined movement direction (step S34). . Thereby, this process is complete | finished. The mouse actuator unit 86 moves the mouse 108 by the determined moving direction and moving amount, that is, by the same moving direction and moving amount as the remote mouse 18. Therefore, the operator can remotely operate the mouse 108 by operating the remote mouse 18.

  Note that the mouse input position determination unit 54 may determine a movement amount smaller than the movement amount of the remote mouse 18 as the movement amount of the mouse actuator unit 86. That is, the mouse input position determination unit 54 may perform dead time compensation. As a result, the mouse input position determination unit 54 may not be able to stop the mouse 108 at the position intended by the operator because the mouse 108 continues to move even when the remote mouse 18 stops moving. Can be reduced.

  Further, the mouse actuator control unit 58 may retract the protrusion 90 at a predetermined timing to separate the bottom surface of the mouse 108 from the moving region G. In this case, the mouse actuator control unit 58 further controls the mouse actuator unit 86 to move the mouse 108 separated from the moving region G to a predetermined position in the moving region G, here the central position of the moving region G. Thereafter, the mouse actuator controller 58 causes the protrusion 90 to protrude so that the bottom surface of the mouse 108 contacts the moving region G. In other words, the mouse actuator control unit 58 may return the mouse 108 to the center position at a predetermined timing regardless of the operation of the remote mouse 18. Thereby, it is possible to suppress the occurrence of a remote operation that attempts to move the mouse 108 to a position outside the movement region G. The predetermined timing can be arbitrarily set. For example, when the operating range of the mouse actuator unit 86 is exceeded, that is, a control for moving the mouse actuator unit 86 to a position outside the moving region G is detected. This is the case. The predetermined timing may be every predetermined time or when a user setting event occurs, for example, when the operator performs a predetermined operation.

  As described above, the operation system 1 according to the present embodiment is an operation system of the control device 100 that controls the device 120 as a control target.

Have The remote input unit 15 is an input unit on which physical input is made by an operator. The remote control unit 12 acquires an input to the remote input unit 15 as remote input data. The operation unit 25 is attached to the input unit 105 of the control device 100 and performs physical input to the input unit 105. The input control unit 22 controls the operation unit 25 so that the same information as the remote input data is input to the input unit 105. The remote target control unit 10 and the target control unit 20 are disconnected from electrical communication with the control device 100.

  The equipment 120 provided in the plant facility R1 is maintained by a maintenance worker of the equipment when trouble occurs or when a periodic maintenance is performed. In performing this maintenance, a maintenance worker may operate the control device 100 of the device 120 by using a control device provided in his / her office, for example, to remotely operate the device 120. When performing remote operation in this way, a control device provided in the office of a maintenance worker may be connected to the control device 100 via a network, and the control device 100 may be remotely operated via the network. In this case, since the control device 100 is connected to the network, there is a risk that unauthorized access may be made via the network. In particular, the equipment 120 of the water treatment plant needs to maintain high information security, and is required to reduce the possibility of unauthorized access.

  The operation system 1 according to the present embodiment is not connected to the control device 100 via a network. In the operation system 1, the input control unit 22 acquires input data of a remote operator (maintenance worker) as remote input data, and the operation unit 25 physically controls the same information as the remote input data. This is input to the input unit 105 of the apparatus 100. Thereby, the operation system 1 enables the operator to remotely operate the control device 100 while cutting off the network connection with the control device 100. Therefore, the operation system 1 can suppress a decrease in information security level when the device 120 is remotely operated. Since the operation system 1 is not connected to the control device 100 via a network, even if the remote target control unit 10 is used illegally, electronic data cannot be extracted from the control device 100, and a virus Cannot be sent. Therefore, the operation system 1 can suppress a decrease in information security level.

  In addition, the control device 100 includes an input area 106A in which the input unit 105 is provided with a plurality of sub-input units corresponding to predetermined predetermined information at positions different from each other. When the operation is performed, input of predetermined information associated with the sub input unit is accepted. Based on the remote input data, the input control unit 22 determines which position in the input region 106A the operation unit 25 performs input, and controls the operation unit 25 so as to input to the determined position in the input region 106A. To do. In the operation system 1, the operation unit 25 performs input at a position determined to be input. Therefore, for example, when the input unit 105 is a keyboard, the operation system 1 can input the same key as the key (sub input unit) remotely input by the operator using the operating unit 25. Therefore, this operation system 1 can perform remote operation more appropriately. The input unit 105 is not limited to a keyboard, and may be a touch panel integrated with a display unit, for example. In this case, the sub input unit is each area when the touch panel is divided into predetermined areas. Even in this case, since the operation system 1 can input (touch) the same area as the area remotely input by the operator, the remote operation can be performed more appropriately.

  The input unit 105 includes a keyboard 106 and a mouse 108. The operation unit 25 includes a keyboard input operation unit 26 and a mouse input operation unit 28. The keyboard input operation unit 26 is attached to the keyboard 106 and performs physical input to a plurality of keys 106B arranged in the input area 106A of the keyboard 106. The mouse input operation unit 28 is attached to the mouse 108, moves the mouse 108, and performs a physical input to the button 108A of the mouse 108. In the operation system 1, the keyboard 106 and the mouse 108 can be appropriately operated by the keyboard input operation unit 26 and the mouse input operation unit 28, so that the remote operation can be performed more appropriately.

  The keyboard input operation unit 26 includes a keyboard rail unit 74 and a keyboard actuator unit 76 having a keyboard rail moving unit 77 and a protruding portion 78.

The keyboard actuator unit 76 is provided on the keyboard rail unit 74, respectively. The keyboard rail moving part 77 is movable along the extending direction of the keyboard rail part 74. The protruding portion 78 can protrude toward the input area 106A. In this operation system 1, since the keyboard input operation unit 26 has such a configuration, the keyboard 106 can be appropriately operated, so that remote operation can be more appropriately performed.

  The remote input data includes character information. The input control unit 22 includes a keyboard input position determination unit 52 and a keyboard actuator control unit 56. The keyboard input position determination unit 52 selects a keyboard actuator unit 76 to be operated among a plurality of keyboard actuator units 76 based on character information, that is, remote input data, and determines a position to move the selected keyboard actuator unit 76. The keyboard actuator control unit 56 moves the keyboard actuator unit 76 selected by the keyboard input position determination unit 52 to the determined position, and causes the projecting portion 78 to project toward the input area 106 </ b> A to input to the input unit 105.
