The embodiments of the present application do not limit the method for determining the health status self-test result corresponding to the workstation group based on the third health status self-test result corresponding to each workstation.

[0077] In the embodiment of the present application, for each workstation, a health status self-test result corresponding to the display and control device in the workstation is obtained, and based on the health status self-test result corresponding to the display and control device, a third health status self-test result corresponding to the workstation is determined, and based on the third health status self-test result corresponding to each workstation, a health status self-test result corresponding to the workstation group is determined. This can improve the efficiency and accuracy of determining the health status self-test result corresponding to the workstation group, and further improve the accuracy and timeliness of the nuclear power equipment status retreat when the health status self-test result corresponding to the workstation group is that the workstation group is in a failed state, thereby ensuring the operational safety of the nuclear power plant.

[0078] It is worth mentioning that when there are multiple non-safety display and control devices in each workstation, if there are a large number of non-safety-level display and control devices in a fault state in the workstation, it will affect the effect of operators using the split-screen non-safety-level display and control devices to monitor the data of safety-level nuclear power equipment and non-safety-level nuclear power equipment, as well as the effect of using the split-screen non-safety-level display and control devices to control the non-safety-level nuclear power equipment, which will in turn affect the operating safety of the nuclear power plant.

[0079] In one embodiment, when there are multiple non-security-level display and control devices in each workstation, determining the third health status self-test result corresponding to the workstation based on the health status self-test results corresponding to the display and control devices includes at least one of the following:

[0080] If the first state self-check result indicates that a safety-level display and control device in the workstation is in a fault state, determining that the third health state self-check result indicates that the workstation is in a fault state;

[0081] When the second status self-test result is that there is a non-safety-level display and control device in the workstation in a fault state, and the proportion of non-safety-level display and control devices in the fault state is greater than or equal to the first ratio, the third health status self-test result is determined to be that the workstation is in a fault state.

[0082] In actual implementation, when there are multiple non-security-level display and control devices in the workstation, if it is obtained that there is a security-level display and control device in the workstation in a fault state, it can be determined that the workstation is in a fault state; if it is obtained that there is a non-security-level display and control device in the workstation in a fault state, and the proportion of non-security-level display and control devices in a fault state is greater than or equal to the first ratio, it can be determined that the workstation is in a fault state.

[0083] Optionally, the first ratio is obtained based on the operating experience of nuclear power plant operators and is used to limit the number of non-safety-level display and control devices in a fault state to a large number.

[0084] The embodiment of the present application determines that the third health status self-test result corresponding to the workstation is that the workstation is in a fault state when it is obtained that there is a security-level display and control device in a fault state in the workstation, and / or determines that the third health status self-test result corresponding to the workstation is that the workstation is in a fault state when it is obtained that there is a non-security-level display and control device in a fault state in the workstation, and the proportion of non-security-level display and control devices in a fault state is greater than or equal to a first ratio. This can improve the efficiency and accuracy of determining that the workstation is in a fault state, and further improve the efficiency and accuracy of determining that the workstation group is in a failed state based on the third health status self-test result corresponding to the workstation.

[0085] It's worth noting that to facilitate monitoring of nuclear power equipment by different management roles within a nuclear power plant, multiple workstations with identical monitoring configurations are typically deployed within the plant. These workstations are grouped together. If a large number of workstations within a group are in a faulty state, this can affect the monitoring effectiveness of the nuclear power equipment and, in turn, the operational safety of the plant.

[0086] In one embodiment, when there are multiple workstations, determining the health status self-test result corresponding to the workstation group based on the third health status self-test result corresponding to each workstation includes:

[0087] Determine the proportion of workstations in a fault state based on the third state self-test result corresponding to each workstation;

[0088] When the proportion of the workstations in the fault state is greater than or equal to the second ratio, it is determined that the health status self-inspection result corresponding to the workstation group is that the workstation group is in the fault state.

[0089] In actual implementation, when there are multiple workstations, the third-state self-test results corresponding to each workstation can be screened to obtain the target result that the workstation is in a faulty state; then the proportion of the target results relative to all the third-state self-test results can be counted to obtain the proportion of workstations in a faulty state; then the proportion of workstations in a faulty state can be compared with the second ratio. When the proportion of workstations in a faulty state is greater than or equal to the second ratio, the health status self-test result corresponding to the workstation group is determined to be that the workstation group is in a faulty state.

[0090] Optionally, the second ratio is determined by operating experience of nuclear power plant operators and is used to limit the proportion of workstations in a fault state to a higher level.

[0091] In the embodiment of the present application, when there are multiple workstations in the workstation group, the proportion of workstations in a faulty state is determined based on the third state self-test result corresponding to each workstation, and when the proportion of workstations in a faulty state is greater than or equal to the second ratio, the health state self-test result corresponding to the workstation group is determined to be that the workstation group is in a faulty state. This can improve the efficiency and accuracy of determining the health state self-test result corresponding to the workstation group, and further improve the efficiency and accuracy of determining that the workstation group is in a failed state based on the health state self-test result corresponding to the workstation group.

[0092] In one embodiment, obtaining the target factors affecting the working status of the workstation group in step S101 includes:

[0093] Monitoring the status of the target monitoring authority and obtaining a status monitoring result of the target monitoring authority; wherein the target monitoring authority includes a first monitoring authority, a second monitoring authority, and a third monitoring authority of the remote shutdown station for nuclear power equipment;

[0094] When the status monitoring result of the target monitoring authority is that the first monitoring authority is in an activated state, and the second monitoring authority and the third monitoring authority are in a locked state, obtaining a target factor affecting the working state of the workstation group;

[0095] After monitoring the status of the target monitoring authority and obtaining the status monitoring result of the target monitoring authority, the device monitoring method further includes:

[0096] When the status monitoring result of the target monitoring authority is that the third monitoring authority is in an activated state, the states of the first monitoring authority and the second monitoring authority are set to a locked state.

[0097] In actual implementation, the above-mentioned workstation group and backup disk are generally set up in the main control room of the nuclear power plant, and a remote shutdown station is also set up outside the main control room. In the event of a fire or thick smoke in the main control room, the operator can activate the remote shutdown station's third monitoring authority over the nuclear power equipment by operating the switch, so that the operator can continue to monitor the nuclear power equipment through the remote shutdown station to ensure the operational safety of the nuclear power plant.

[0098] Optionally, the above-mentioned electronic device can also communicate with the switching switch; in actual implementation, the electronic device can respond to the operation information corresponding to the third monitoring authority of the remote shutdown station over the nuclear power equipment activated by the switching switch, determine the state of the third monitoring authority of the remote shutdown station over the nuclear power equipment to be an activated state, and set the first monitoring authority of the above-mentioned workstation group over the nuclear power equipment and the second monitoring authority of the backup disk over the nuclear power equipment to a locked state, so that the monitoring instructions of the workstation group over the nuclear power equipment and the monitoring instructions of the backup disk over the nuclear power equipment are locked.

[0099] In addition, to ensure the necessity of executing the above steps S101 to S103, when it is determined that the first monitoring authority of the workstation group over the nuclear power equipment is in an activated state, and the second monitoring authority of the backup disk over the nuclear power equipment and the third monitoring authority of the remote shutdown station over the nuclear power equipment are in a locked state, the step of obtaining the target factors affecting the working status of the workstation group in step S101 can be executed.

[0100] The embodiment of the present application obtains the status monitoring result of the target monitoring authority by monitoring the status of the target monitoring authority, and obtains the target factors affecting the working status of the workstation group when the status monitoring result of the target monitoring authority is that the first monitoring authority is in an activated state, and the second monitoring authority and the third monitoring authority are in a locked state, and sets the status of the first monitoring authority and the second monitoring authority to a locked state when the status monitoring result of the target monitoring authority is that the third monitoring authority is in an activated state, thereby increasing the necessity of retreating the status of nuclear power equipment and improving the operating safety of nuclear power plants.

[0101] In a specific embodiment, the nuclear power plant equipment monitoring method provided in the embodiment of the present application can be applied to Figure 2 The digital control system (DCS) architecture of the main control room (MCR) of a nuclear power plant is shown in FIG. Figure 2As shown, the DCS architecture includes a backup panel (BUP) and an operator workstation group (OWP), which includes four workstations (OWP1, OWP2, OWP3, and OWP4). The DCS architecture also includes a safety-level DCS and a non-safety-level DCS. Safety-level nuclear power equipment and non-safety-level display and control equipment communicate through a first gateway (GW1) and a second gateway (GW2) set in the safety-level DCS (equivalent to the above-mentioned first communication link including GW1 nodes and GW2 nodes). Safety-level display and control equipment and non-safety-level display and control equipment communicate through a third gateway (GW3) and a fourth gateway (GW4) set in the non-safety-level DCS (equivalent to the above-mentioned second communication link including GW3 nodes and GW4 nodes). In the non-safety-level DCS, non-safety-level display and control equipment (NC-VDU) and non-safety-level nuclear power equipment communicate through a monitoring network, a real-time server, and a system network (equivalent to the above-mentioned third communication link including a monitoring network node, a real-time server node, and a system network node). Optionally, the system network and field control station (FCS) can be divided into the Level 1 layer of the non-safety-level DCS, and the real-time server, monitoring network, and OWP can be divided into the Level 2 communication layer of the non-safety-level DCS. In addition, in the non-safety-level DCS, the computing server and the real-time server are connected through the monitoring network. The real-time server can be used to collect data from safety-level nuclear power equipment and non-safety-level nuclear power equipment in real time, and transmit the collected data to the computing server for processing, while sending the operator's control instructions for the nuclear power equipment to the nuclear power equipment; the computing server can organize and save the data of the nuclear power equipment collected by the real-time server, and calculate the corresponding monitoring indicator values ​​of the nuclear power equipment based on the data of the nuclear power equipment to support the workstation group's monitoring functions such as alarm monitoring of nuclear power equipment, nuclear power plant operating condition monitoring, and thermal power monitoring.

[0102] Please combine Figure 2 and Figure 3 In actual implementation, the communication status of GW1, GW2, GW3 and GW4 can be monitored. If it is detected that any node among GW1, GW2, GW3 and GW4 is in an abnormal communication state, it can be determined that the above-mentioned first communication link and / or the above-mentioned second communication link is in a disconnected state (which can also be called the communication failure between the safety-level DCS and the non-safety-level DCS), and then it can be determined that the workstation group is in a failed state; then the monitoring authority of the nuclear power equipment can be switched from the first monitoring authority of OWP to the second monitoring authority of BUP, so that the nuclear power equipment status is retreated to ensure the operational safety of the nuclear power plant.

[0103] Please combine Figure 2 and Figure 4In actual implementation, the communication status of the monitoring network, real-time server and system network can be monitored. If the communication status of any communication node in the monitoring network, real-time server and system network is detected to be in an abnormal communication state, it can be determined that the above-mentioned third communication link is in a disconnected state (also known as the communication failure between Level 1 and Level 2), and then it can be determined that the workstation group is in a failed state; then the monitoring authority of the nuclear power equipment can be switched from the first monitoring authority of OWP to the second monitoring authority of BUP, so that the nuclear power equipment status is retreated to ensure the operation safety of the nuclear power plant.

[0104] Please combine Figure 2 and Figure 5 , each workstation (OWPi, i is any integer from 1 to 4) in the OWP can include 5 NC-VDUs and 2 VDUs. In actual implementation, for each OWPi, the first health status self-test result of each S-VDU in the OWPi and the second health status self-test result of each NC-VDU can be obtained. If the first health status self-test result indicates that any S-VDU in the OWPi is in a faulty state (also known as S-VDU unavailable), it can be determined that the OWPi is in a faulty state; and / or if the second health status self-test result indicates that the proportion of NC-VDUs in the OWPi in a faulty state is greater than or equal to 40%, it can be determined that the OWPi is in a faulty state. Then, the number of OWPi in a faulty state can be counted. If the proportion of the number of OWPi in a faulty state is greater than or equal to 50%, it can be determined that the OWP is in a faulty state, and further, it can be determined that the OWP is in a failed state. Then, the monitoring authority of the nuclear power equipment can be switched from the first monitoring authority of the OWP to the second monitoring authority of the BUP, so that the nuclear power equipment status is retreated to ensure the operational safety of the nuclear power plant.

[0105] Please combine Figure 2 and Figure 6If it is detected that the BUP's second monitoring authority for nuclear power equipment and the remote shutdown station's (RSS) third monitoring authority for nuclear power equipment are in a locked state, the above-mentioned target factors affecting the working state of the workstation group can be monitored; if it is detected that any of the following situations exists in the DCS architecture: communication failure between the safety-level DCS and the non-safety-level DCS, communication failure between Level 1 and Level 2, abnormal operation of the computing server, and failure of the OWP, it can be determined that the OWP is in a failed state; then the monitoring authority of the nuclear power equipment can be switched from the OWP's first monitoring authority for the nuclear power equipment to the BUP's second monitoring authority for the nuclear power equipment, so that the nuclear power equipment status is retreated and the operational safety of the nuclear power plant is ensured. If it is detected that the RSS's third monitoring authority for nuclear power equipment is in an activated state, the OWP's first monitoring authority for the nuclear power equipment and the BUP's second monitoring authority for the nuclear power equipment can be set to a locked state to block the control instructions of the OWP and BUP for the nuclear power equipment.

[0106] Optionally, the electronic device may implement switching among the first monitoring authority, the second monitoring authority, and the third monitoring authority through a SWB algorithm block; optionally, the SWB algorithm block may convert different monitoring authorities based on the following logical operations:

[0107] s1=0, s2=0, y=x1;

[0108] s1=1, s2=0, y=x2;

[0109] s2=1, no matter what the value of s1 is, y=x3;

[0110] Optionally, x1, x2, and x3 represent OWP, BUP, and RSS monitoring instructions for nuclear power equipment, respectively. s1=0 may indicate that OWP is not in an invalid state, and s2=0 may indicate that no operation information corresponding to the switch activating the third RSS monitoring authority for nuclear power equipment (equivalent to MCR being available) has been received. When s1=0 and s2=0, the SWB algorithm block may output the OWP monitoring instruction to the nuclear power equipment, which is equivalent to the nuclear power equipment's monitoring authority being the first monitoring authority.

[0111] In addition, s1=1 may indicate that OWP is in a failed state. When s1=1 and s2=0, the SWB algorithm block may output a BUP monitoring instruction to the nuclear power equipment, which is equivalent to the monitoring authority of the nuclear power equipment being the second monitoring authority.

[0112] In addition, s2=1 can indicate that the operation information corresponding to the third monitoring authority of RSS for nuclear power equipment is received by the switching switch (equivalent to MCR being unavailable). When s2=1, no matter what the value of s1 is, the SWB algorithm block can output the RSS monitoring instruction to the nuclear power equipment, which is equivalent to the monitoring authority of the nuclear power equipment being the above-mentioned third monitoring authority.

[0113] This embodiment of the present application uses the failure of the OWP as a trigger condition for automatically switching the OWP / BUP monitoring authority for nuclear power equipment. Upon detecting that the OWP is in a failure state, the OWP's monitoring authority for nuclear power equipment is directly switched to the BUP's monitoring authority for nuclear power equipment. This eliminates the need for an OWP / BUP switch on the control panel in the main control room. This not only reduces the space requirements for the control panel in the main control room, but also improves the accuracy and timeliness of nuclear power equipment status recall, thereby ensuring the operational safety of the nuclear power plant. Furthermore, a single SWB algorithm block is used to implement the switching of monitoring instructions for nuclear power equipment between OWP, BUP, and RSS, simplifying the switching logic for monitoring instructions and improving the practicality and cost-effectiveness of the nuclear power plant equipment monitoring method provided by this embodiment of the present application.

[0116] The state determination module 702 is configured to determine that the working state is a failure state when the target factor satisfies the target condition; wherein the target condition includes at least one of the following: the communication link is disconnected; the health status self-check result indicates that the workstation group is in a failure state; the computing server is in an abnormal operation state;
