Description

  The present invention relates to a remote monitoring control device that controls equipment provided in a remote place.

  Conventionally, there has been a remote monitoring and control device used for controlling local equipment installed at a site such as a substation from a remote location (control station). For example, the remote monitoring and control apparatus is installed in a slave station where local equipment is installed, and constitutes a remote monitoring and control system together with a control station system installed in a control station (parent station). Such a remote monitoring control system realizes operation of local equipment from a remote place (control station) by performing communication between the remote monitoring control device and the control station system.

  In the conventional remote monitoring and control system, if the control operation from the control center system could not be executed (becomes refractory), whether the cause of the refractory movement is a fault on the remote monitoring and control device side It was not possible to determine at the control station whether the problem was on the equipment side. For this reason, in the past, when refractory movements occurred, the workers headed to the site and conducted a site survey to identify the failure location. After investigating the location of the defect, repair parts were prepared and repaired. As described above, in the conventional remote monitoring and control system, the cause of the refractory movement is identified and the burden on the worker who responds is large, and it takes time to complete the response.

  As one of the solutions for the above problems, for example, there has conventionally been a technique in which a self-inspection circuit is provided in a control circuit of a remote monitoring control device so that the presence or absence of an abnormality in the control circuit can be detected. . Conventionally, for example, control information transmitted from a control center system is received, information on the detected abnormality is detected by detecting the presence or absence of each relay selected and controlled by the remote monitoring control device based on the received control information. Has been added to the display / measurement information and transmitted to the control center system (see, for example, Patent Document 1 below).

It cannot be determined whether there is a problem or whether there is a problem with the local equipment. For this reason, the above-described conventional technique has a problem that it cannot be determined at the control station whether the cause of the refractory action is a fault on the remote monitoring control device side or a fault on the local equipment side. there were.

  In addition, the conventional technique described in the above-described Patent Document 1 indicates the location where a failure occurs when the display does not change and the refractory movement occurs even though the control circuit of the remote monitoring control device is normal. There was a problem that it was not possible to identify and the reliability of identifying the location where the defect occurred was inferior.

In addition, when the abnormality determination unit 209 determines that an abnormality has occurred in the remote monitoring control device 130 and the local device 120, the output information (response signal) includes information indicating an abnormality occurrence location.

  The output unit 211 outputs the output information generated by the output information generation unit 210 to the control center system 110. Specifically, the output unit 211 outputs, for example, the display information received by the display information input unit 205, the determination result of the abnormality determination unit 209, and the operation state of the local device 120 to the control center system 110.

  The control center system 110 receives the display information output from the output unit 211 and the determination result of the abnormality determination unit 209 and generates notification information based on the received display information and the determination result of the abnormality determination unit 209. Then, the control center system 110 displays the notification information generated on a display included in a computer device such as a personal computer that implements the control station system 110, or outputs a sound based on the generated notification information, thereby enabling remote control. The state of the monitoring control device 130 and the local device 120 is notified.

  The control center system 110 includes means for displaying on a screen or the like based on the notification information generated by the control center system 110 based on the output information output from the remote monitoring control device 130 according to the embodiment of the present invention. Specifically, there are contents of operation input performed in the control center system 110 and response contents corresponding to the operation input.

Contains. In addition, the response result includes information indicating the cause of the refractory response when the control station system 110 is refractory to the control according to the operation input received.

  In the control center system 110 provided with the conventional remote monitoring control device 130, the remote monitoring control device 130 does not output information indicating the cause of the refractory movement to the control center system 110. Information indicating the cause of occurrence is not notified.

  Under normal conditions, when the operator performs an input operation for changing the state of the local device 120 from “OFF” to “ON” with respect to the control center system 110, the control center system 110 controls the remote monitoring control device 130. Then, control information for setting the state of the local device 120 to “ON” is output.

  When the control information output from the control center system 110 is control information for setting the operation state of the local device 120 to “ON”, the remote monitoring control device 130 operates the local device 120 with respect to the operation of the local device 120. A device control signal for setting the state to “ON” is output. The control monitoring circuit 133 included in the remote monitoring control device 130 detects that a device control signal for setting the operation state of the local device 120 to “ON” is output from the remote monitoring control device 130 to the local device 120.

  If the device control signal output from the remote monitoring control device 130 is control information that sets the state of the local device 120 to “ON”, the local device 120 sets its own operation state to “ON”, and performs remote monitoring control. An operation signal (“ON” signal) indicating that the operation state of the local device 120 itself is “ON” is output to the device 130. When receiving the operation signal output from the local device 120, the remote monitoring control device 130 outputs a response signal corresponding to the received operation signal to the control center system 110. The display monitoring circuit 134 included in the remote monitoring control device 130 detects that the remote monitoring control device 130 has received the “ON” signal of the local device 120.

  Based on the detection result of the control monitoring circuit 133 and the detection result of the display monitoring circuit 134, the remote monitoring control device 130 is configured so that the local device 120 and the remote monitoring control device 130 are properly operated according to the control information from the control center system 110. Determine if it worked.

  Specifically, the remote monitoring control device 130 receives the device control signal corresponding to the control information received from the control center system 110 based on the detection result of the control monitoring circuit 133 and the detection result of the display monitoring circuit 134. Whether the operation signal corresponding to the device control signal is received from the local device 120, the response signal corresponding to the operation signal received from the local device 120 is output to the control center system 110, etc. A response signal corresponding to the determination result is output.

  Based on the detection result of the control monitoring circuit 133, the remote monitoring control device 130 detects that the remote monitoring control device 130 has output a device control signal for setting the operation state of the local device 120 to “ON” for a predetermined time. Based on the detection result of the display monitoring circuit 134, the operating state of the local device 120 at the time when (for example, 10 seconds) elapses is determined.

  When the local device 120 is defective and cannot operate according to the device control signal output from the remote monitoring control device 130, the operation state of the local device 120 is the remote monitoring control device for the local device 120. Regardless of whether or not a device control signal is output from 130, the signal remains “OFF” (when the operation state of the local device 120 is “ON”, the signal remains “ON”). That is, an operation signal indicating that the local device 120 is in the “OFF” state is output from the local device 120 to the remote monitoring control device 130. In this case, a response signal indicating that the local device 120 is in the “OFF” state is output from the remote monitoring control device 130 to the control center system 110.

  The remote monitoring control device 130 outputs from the remote monitoring control device 130 to the remote monitoring control device 130 from the local device 120 when a predetermined time elapses after outputting the control information for setting the operation state of the local device 120 to “ON”. On the other hand, when the operation signal output is a “OFF” signal, a response signal indicating that the local device 120 is refractory due to a device abnormality is output. In this case, the control center system 110 informs that the device is not responsive due to the occurrence of a device abnormality in which the local device 120 is not operating based on the response signal and the response signal output from the remote monitoring control device 130. Thereby, it is possible to guide the operator at the control station that the local device 120 is abnormal.

  As described above, the remote monitoring control device 130 of this embodiment detects the device control signal in the control monitoring circuit 133 after receiving the input of the “ON” signal or the “OFF” signal from the control center system 110. If the display monitoring circuit 134 cannot detect a signal indicating a change in the operation state of the local device 120 due to the refractory movement of the local device 120, it is determined that the response is due to an abnormality in the local device 120.

  Based on the detection result of the control monitoring circuit 133, the remote monitoring control device 130 receives a predetermined time (for example, 10 seconds) after receiving control information from the control center system 110 to set the operation state of the local device 120 to “ON”. It is determined whether or not a device control signal for setting the operation state of the local device 120 to “ON” has been output from the remote monitoring control device 130 by the time elapsed.

  Although the remote monitoring control device 130 has received control information from the control center system 110 to set the operation state of the local device 120 to “ON”, the remote monitoring control device 130 has received a predetermined time (for example, 10 seconds) after receiving the control information. When the device control signal for setting the operation state of the local device 120 to “ON” has not been output from the remote monitoring control device 130 at the time when the time has elapsed, the control circuit related to the output of the device control signal such as the control output unit 132 is abnormal A response signal indicating that (control circuit abnormality) has occurred is output. In this case, an operation signal indicating that the local device 120 is in the “OFF” state is output from the local device 120 to the remote monitoring control device 130. In this case, a response signal indicating that the local device 120 is in the “off” state is output from the remote monitoring control device 130 to the control center system 110.

  In this case, the control center system 110 notifies that a control circuit abnormality has occurred based on the response signal and response signal output from the remote monitoring control device 130. Thereby, it is possible to guide the operator in the control station 102 that the control circuit of the remote monitoring control device 130 is abnormal.

  As described above, the remote monitoring control device 130 according to this embodiment receives the input of the “ON” signal or the “OFF” signal from the control center system 110 and then controls the control monitoring circuit due to an abnormality in the remote monitoring control device 130. If the device control signal cannot be detected in 133 and the local device 120 does not operate, it is determined that the response is due to the control circuit abnormality.

  Based on the detection result of the display monitoring circuit 134, the remote monitoring control device 130 detects that the “ON” signal indicating that the operation state of the local device 120 is “ON” from the local device 120 is received. Whether or not an operation signal indicating that the local device 120 is in the “ON” state is output from the local device 120 to the remote monitoring control device 130 when a predetermined time (for example, 10 seconds) elapses. to decide.

  The remote monitoring control device 130 outputs to the control center system 110 from the remote monitoring control device 130 even though the “on” signal indicating that the operation state is the “on” state is output from the local device 120. When the response signal is an operation signal indicating that the local device 120 is in the “off” state, an abnormality (display circuit abnormality) has occurred in the display circuit related to reception of the display control signal in the remote monitoring control device 130 A response signal indicating that is output. In this case, a response signal indicating that the local device 120 is in the “OFF” state is output from the remote monitoring control device 130 to the control center system 110.

  In this case, the control center system 110 notifies that a display circuit abnormality has occurred based on the response signal and the response signal output from the remote monitoring control device 130. Thereby, it is possible to guide the operator at the control station 102 that the display circuit of the remote monitoring control device 130 is abnormal.

  As described above, the remote monitoring control device 130 according to this embodiment receives the input of the “ON” signal and the “OFF” signal from the control center system 110 and then outputs the device control signal in the control monitoring circuit 133. Although the local device 120 operates normally based on the device control signal, the display monitoring circuit 134 cannot detect the display information due to an abnormality in the remote monitoring control device 130, and the local device 120 If the current operating state cannot be output to the control center system 110, it is determined that the response is due to an abnormality in the display circuit. The conventional remote monitoring control device does not include the control monitoring circuit 133 and the display monitoring circuit 134 as compared with the remote monitoring control device 130 according to the embodiment of the present invention.

  The conventional remote monitoring control device is based on the control information output from the control station system 110 and the response signal output from the conventional remote monitoring control device to the control station system 110, and the local equipment 120 and the conventional remote monitoring control device. It was determined whether the device was operating normally. Specifically, the conventional remote monitoring and control apparatus determines whether or not a response signal corresponding to the control information output from the control center system 110 has been output, thereby determining the local device 120 and the conventional remote monitoring and control apparatus. Was determining if was working properly.

  In the conventional remote monitoring and control apparatus, when an equipment abnormality occurs in the local equipment 120 and the operation state cannot be changed according to the equipment control signal, the local equipment is monitored according to the control information output from the control center system 110. A device control signal that sets the operation state of the local device 120 to the “ON” state is output to the device 120, but the local device 120 cannot change the operation state. The display information output to the control device indicates the “OFF” state.

  In this case, the response signal output from the conventional remote monitoring control device to the control center system 110 indicates that the local device 120 is in the “OFF” state. Thus, when the control information output from the control center system 110 does not correspond to the response signal, the conventional remote monitoring and control apparatus outputs a response signal indicating that the control center system 110 is refractory. To do.

  In the conventional remote monitoring and control apparatus, when an abnormality occurs in the control output PI / O 104 provided with the control output unit 132 and the device control signal cannot be output, the control information output from the control center system 110 is changed. Since the device control signal cannot be output, there is no change in the operating state of the local device 120, and the display information output from the local device 120 to the conventional remote monitoring control device indicates the “OFF” state.

  In this case, the response signal output from the conventional remote monitoring control device to the control center system 110 indicates that the local device 120 is in the “OFF” state. Thus, when the control information output from the control center system 110 does not correspond to the response signal, the conventional remote monitoring and control apparatus outputs a response signal indicating that the control center system 110 is refractory. To do.

  In the conventional remote monitoring and control apparatus, when an abnormality occurs in the display input PI / O 105 provided with the display input unit 135 and the display information output from the local device 120 cannot be received, Although the device control signal is output, the display information output from the local device 120 cannot be received.

  For this reason, the response signal output from the conventional remote monitoring and control apparatus to the control center system 110 indicates that the field device 120 is in the “OFF” state. Thus, when the control information output from the control center system 110 does not correspond to the response signal, the conventional remote monitoring and control apparatus outputs a response signal indicating that the control center system 110 is refractory. To do.

  Thus, conventionally, in the case where a response signal indicating refractory movement is output from the remote monitoring and control apparatus, the control center system 110 determines whether the responsive movement is caused by the remote monitoring and control apparatus or the local equipment. The control center (master station) 102 could not determine whether 120 was the cause of refractory movement.

  On the other hand, according to the control center system 110 using the remote monitoring control device 130 of the embodiment according to the present invention, as described above, it is a refractory movement due to a control circuit abnormality or a refractory movement due to a display circuit abnormality. The control station (master station) 102 can determine whether there is a refractory movement due to device abnormality.

In step S302, when a device control signal is output from the remote monitoring control device 130 to the corresponding local device 120 (step S302: Yes), the local device 120 serving as the output destination of the device control signal is transmitted from the local device 120. It is determined whether or not an input of an operation display signal has been accepted (step S303). In step S303, it is determined whether or not an input of a device operation display signal has been accepted after a predetermined time (for example, 10 seconds) elapses after the device control signal is output in step S302: Yes.

  In step S303, when the input of the operation display signal of the local device 120 is received (step S303: Yes), based on the detection result of the display monitoring circuit 134, the local display that has received the input of the operation display signal in step S303: Yes.

Output (step S305), the series of processing is terminated. In this case, the device operation corresponding to the device operation command process performed on the control center system 110 is completed.

  On the other hand, when the PI / O control unit 131 has not received the display information output from the local device 120 in step S304 even though the input of the operation display signal is received in step S303: Yes (step S304: No), it is determined that an abnormality has occurred in the display circuit in the remote monitoring control device 130, and response information indicating "refractory movement (display circuit abnormality)" is output to the control center system 110 (step S306). ), A series of processing ends. As a result, the control center system 110 can notify that the device operation corresponding to the device operation command processing performed on the control center system 110 has not been completed and the cause of the refractory movement. .

  In step S303, when the input of the operation display signal of the local device 120 is not received from the local device 120 that is the output destination of the device control signal output in step S302: Yes (No in step S303), the local device 120 It is determined that an abnormality has occurred, response information indicating “refractory movement (equipment abnormality)” is output to the control center system 110 (step S306), and a series of processing ends. As a result, the control center system 110 can notify that the device operation corresponding to the device operation command processing performed on the control center system 110 has not been completed and the cause of the refractory movement. .

  In step S <b> 302, the remote monitoring control device 130 applies the corresponding local device 120 to the control center system 110, even though the processing for controlling the operation of the local device 120 (device operation command processing) is performed. If the device control signal has not been output (step S302: No), it is determined that an abnormality has occurred in the monitoring circuit in the remote monitoring and control device 130, and the control station system 110 is informed of "non-responsive (control circuit abnormality ) "Is output (step S306), and the series of processing ends. Thereby, in the control center system 110, it can be notified that the device operation according to the device operation command processing performed on the control center system 110 is not completed and the cause of the refractory movement. .

  In the conventional remote monitoring and control apparatus, the control center system 110 can notify that the device operation corresponding to the device operation command processing performed on the control center system 110 is incomplete, The cause of the response cannot be reported.

  As described above, according to the remote monitoring and control apparatus 130 of the embodiment of the present invention, when a refractory movement in which the operation according to the control information output from the control center system 110 is not normally completed occurs, the remote monitoring and control is performed. The operator at the control station 102 can be informed of whether the cause of the refractory movement in the system 100 is in the remote monitoring control device 130 or the local device 120.
