Background Art

[0002] The on-line monitoring system for a pumped storage power station is a real-time detection system specifically designed for a pumped storage power station, aiming to monitor, analyze, and manage the operation status of the power station to ensure the safe and efficient operation of the power station equipment. The on-line monitoring system for a pumped storage power station usually adopts a hierarchical distributed structure, generally consisting of an upper computer unit, a data acquisition unit, and its sensor unit. The on-line monitoring system for a pumped storage power station can monitor the operation status of the pumped storage unit in real time by monitoring vibration, swing, pressure (pulsation), air gap, magnetic flux density, noise, temperature, etc., which helps to accurately diagnose abnormal conditions and detect potential faults at an early stage.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The method for troubleshooting the communication failure between the upper and lower computers of the on-line monitoring system for a pumped storage power station provided by the embodiments of the present application can be applied to, for example Figure 1In the online monitoring system 100 of the pumped-storage power station shown. The online monitoring system 100 of the pumped-storage power station may include a sensor 101, a lower computer data acquisition device 102, an optical and electrical switch 103 of the lower computer, a lower computer optical fiber box 104, an upper computer optical fiber box 105, an optical and electrical switch 106 of the upper computer, and an upper computer server 107. Among them, the sensor can be used to measure parameters related to the unit stability such as the large shaft swing, frame vibration, and pressure pulsation; the lower computer data acquisition device can be used to preprocess and collect the analog signals transmitted by the sensor, convert them into digital signals and then process and process them to obtain various characteristic parameters that can reflect the operating state of the unit; the optical and electrical switch of the lower computer can be used to convert various characteristic parameters processed by the lower computer from electrical signals into optical signals and then transmit them to the optical and electrical switch of the upper computer; the lower computer optical fiber box can be used to provide a fiber interface for the optical and electrical switch of the lower computer, and at the same time the optical fiber in the box is connected to the upper computer optical fiber box; the upper computer optical fiber box can be used to provide a fiber interface for the optical and electrical switch of the upper computer, and at the same time the optical fiber in the box is connected to the lower computer optical fiber box; the optical and electrical switch of the upper computer can be used to receive the optical signals containing various characteristic parameters transmitted by the optical and electrical switch of the lower computer, and at the same time convert the optical signals into electrical signals and then transmit them to the upper computer server; the upper computer server is a computer system running the upper computer software, which can be used to store various characteristic parameters transmitted by the lower computer, and at the same time perform data forwarding and transmit the characteristic parameters to other systems.

[0052] The online monitoring system of the pumped-storage power station may further include a monitoring center controller 108, and this monitoring center controller can be responsible for managing, coordinating and processing various monitoring and control tasks. When there is a communication failure between the upper computer and the lower computer, the monitoring center controller 108 detects whether the numerical display of the lower computer is normal; when the numerical display of the lower computer is normal, the monitoring center controller 108 detects the network connectivity between the upper computer and the lower computer; when the network connectivity is normal, the monitoring center controller 108 detects the network configuration of the upper computer and the lower computer; the network configuration includes the settings of the gateway and subnet mask of the upper computer and the lower computer; when the network configuration is normal, the monitoring center controller 108 simulates the function of the upper computer through a test device and detects the signal reception status between the test device and the lower computer; the test device is connected to the optical and electrical switch of the upper computer or the lower computer; the monitoring center controller 108 determines the troubleshooting result of the online monitoring system of the pumped-storage power station according to the signal reception status.

[0053] In an exemplary embodiment, as Figure 2 shown, a method for troubleshooting the communication failure between the upper and lower computers of an online monitoring system of a pumped-storage power station is provided. Taking this method applied to Figure 1 the online monitoring system of the pumped-storage power station as an example for illustration, it includes:

[0054] Step S202: When there is a communication failure between the host computer and the slave computer, detect whether the numerical display of the slave computer is normal.

[0055] Among them, the host computer can refer to a computer system with powerful computing power and data processing capabilities in the on-line monitoring system of a pumped-storage power station, which is responsible for the monitoring of the entire system, the issuance of instructions, data collection, processing and analysis, and user interaction. The slave computer can be a device or controller directly connected to hardware such as sensors and actuators in the system, and can execute specific control instructions issued by the host computer, such as the output of switch signals, the adjustment of analog quantities, data collection, etc. Exemplarily, the host computer here can refer to the host computer server, and the slave computer here can refer to the slave computer data acquisition device.

[0056] Exemplarily, the monitoring center controller can detect whether the numerical display of the host computer is abnormal. If the numerical display of the host computer is abnormal, it can be determined that there is a communication failure between the host computer and the slave computer. Alternatively, an abnormal detection module can be set in the host computer software. The host computer captures communication abnormal events and triggers an alarm mechanism. After receiving the alarm triggered by the host computer, the monitoring center controller can determine that there is a communication failure between the host computer and the slave computer.

[0057] In one of the embodiments, detecting whether the numerical display of the slave computer is normal may include:

[0058] The monitoring center controller simulates the signal waveform of the sensor connected to the slave computer through a function signal generator and inputs the signal waveform into the slave computer; when the numerical value displayed by the slave computer matches the signal waveform simulated by the function signal generator, it is determined that the numerical display of the slave computer is normal; when the numerical value displayed by the slave computer does not match the signal waveform simulated by the function signal generator, it is determined that the numerical display of the slave computer is abnormal.

[0059] Step S204: When the numerical display of the slave computer is normal, detect the network connectivity between the host computer and the slave computer.

[0060] Among them, network connectivity can refer to the state of whether the host computer and the slave computer can communicate normally through the physical link and network protocol.

[0061] Exemplarily, to detect the network connectivity between the upper computer and the lower computer, it can be tested by the Packet Internet Groper (ping) instruction in network communication. Specifically, the monitoring center controller can control the upper computer server to send ping packets to the lower computer data acquisition device, and determine whether the ping packets sent from the upper computer server can reach the lower computer data acquisition device. When the lower computer data acquisition device receives the ping packet, it can send a confirmation receipt notice to the monitoring center controller. When the monitoring center controller receives the confirmation receipt notice within the preset duration, it can confirm that the network connectivity between the upper computer and the lower computer is normal; if the monitoring center controller does not receive the confirmation receipt notice within the preset duration, it can confirm that the network connectivity between the upper computer and the lower computer is abnormal.

[0062] Step S206, when the network connectivity is normal, detect the network configuration of the upper computer and the lower computer.

[0063] Among them, the network configuration includes the settings of the gateway and subnet mask of the upper computer and the lower computer.

[0064] Among them, the network configuration may include the basic parameter devices required for the upper computer and the lower computer to participate in network communication, including Internet Protocol (IP) address, gateway, subnet mask, etc.

[0065] Among them, the gateway can refer to the egress device for a network device (such as the upper computer or the lower computer) to access other subnets or external networks, usually the address of a router or a layer 3 switch. If the upper computer or the lower computer needs to communicate with other subnets or external networks, the gateway must be correctly configured. Incorrect gateway configuration may cause the device to be unable to send data to other subnets.

[0066] Among them, the subnet mask is used to divide the IP address into a network part and a host part, so as to determine the subnet range where the device is located. The subnet mask helps network devices determine whether the target address belongs to the same subnet. Incorrect subnet mask configuration may cause the device to be unable to recognize other devices within the same subnet, affecting communication. For example, if the gateway is configured incorrectly, the network device cannot access other subnets or external networks, affecting data transmission and system functions; if the subnet mask is configured incorrectly, the upper computer and the lower computer may be unable to correctly determine whether they are within the same subnet due to incorrect subnet division, resulting in communication interruption or data forwarding failure.

[0067] Exemplarily, to detect the network configuration of the upper computer and the lower computer, the monitoring center controller can automatically obtain the network configuration parameters of the upper computer and the lower computer through a script, parse the network configuration parameters through regular expressions or matching tools, and compare them with the preset network planning parameters to determine whether the network configuration of the upper computer and the lower computer is normal; or, the network configuration parameters of the upper computer and the lower computer can be obtained from the network management platform through the Simple Network Management Protocol (SNMP) and compared with the preset values to determine whether the network configuration of the upper computer and the lower computer is normal.

[0068] Step S208, when the network configuration is normal, simulate the function of the upper computer through a test device and detect the signal reception status between the test device and the lower computer.

[0069] Among them, the test device is connected to the optical and electrical switch of the upper computer or the lower computer.

[0070] In specific implementation, the test device can be a computer or a laptop configured with the software of the upper computer. Through the software of the upper computer, the test device can establish a connection with the lower computer through a network protocol, send requests or receive data, and parse and display or store the data received from the lower computer, so as to be able to act as the role of the upper computer and simulate the function of the upper computer. Therefore, copy the software of the upper computer to the test device, connect the test device to the optical and electrical switch of the upper computer or the lower computer, and the function of the upper computer can be simulated through the test device.

[0071] Exemplarily, when the test device is connected to the optical and electrical switch of the lower computer, the test path is: test device Optical and electrical switch of the lower computer Data acquisition device of the lower computer.

[0072] Exemplarily, when the test device is connected to the optical and electrical switch of the upper computer, the test path is: test device Optical fiber box of the upper computer Optical fiber box of the lower computer Optical and electrical switch of the lower computer Data acquisition device of the lower computer.

[0073] Among them, the signal reception status may include the integrity, correctness and stability of the signal.

[0074] In specific implementation, detecting the signal reception status between the test device and the lower computer may be detecting whether the test device can receive complete and correct data sent by the lower computer. Exemplarily, if the test device cannot receive any signal sent by the lower computer, or the data received by the test device is incomplete, has a large delay or frequent packet loss, it can be determined that the signal reception status between the test device and the lower computer is abnormal; if the above conditions do not occur, it can be determined that the signal reception status between the test device and the lower computer is normal.

[0075] Step S210, determine the troubleshooting result of the on-line monitoring system of the pumped storage power station according to the signal reception status.

[0076] In the previous steps, such as numerical display check, network connectivity check, network configuration verification, the possible fault range has been gradually narrowed down. By simulating the function of the upper computer with the test device, detecting the signal reception status between the test device and the lower computer, and through the signal reception status, the accurate location and solution of the fault are finally obtained.

[0077] Exemplarily, when the test device is connected to the optical-electrical switch of the lower computer, if the signal reception status is abnormal, it can be determined that there is a problem with the communication link of "test device optical-electrical switch of the lower computer lower computer data acquisition device" or there is a problem with the devices therein; when the test device is connected to the optical-electrical switch of the upper computer, if the signal reception status is abnormal, it can be determined that there is a problem with the communication link of "test device optical fiber box of the upper computer optical fiber box of the lower computer optical-electrical switch of the lower computer lower computer data acquisition device" or there is a problem with the devices therein.

[0078] Assume that the above problems have been solved, and when the test device is connected to the optical-electrical switch of the lower computer and when the test device is connected to the optical-electrical switch of the upper computer, the signal reception status is normal. Then, it can be detected again whether there is still a communication fault between the upper computer and the lower computer. If there is no longer a communication fault, it is determined that the troubleshooting result of the on-line monitoring system of the pumped storage power station has been completed; if there is still a communication fault, a serious fault notification can be directly sent to notify the manual processing.

[0079] In the above method for troubleshooting the communication failure between the upper computer and the lower computer of the pumped-storage power station online monitoring system, when there is a communication failure between the upper computer and the lower computer, it is detected whether the numerical display of the lower computer is normal; when the numerical display of the lower computer is normal, the network connectivity between the upper computer and the lower computer is detected; when the network connectivity is normal, the network configuration of the upper computer and the lower computer is detected; the network configuration includes the settings of the gateway and subnet mask of the upper computer and the lower computer; when the network configuration is normal, the function of the upper computer is simulated by a test device, and the signal reception status between the test device and the lower computer is detected; the test device is connected to the optical and electrical switch of the upper computer or the lower computer; according to the signal reception status, the troubleshooting result of the pumped-storage power station online monitoring system is determined. By detecting multi-dimensional information layer by layer from the numerical display of the lower computer to the network configuration and then to the signal reception status, the systematic troubleshooting of the communication failure between the upper computer and the lower computer is realized, which can effectively avoid inaccurate or delayed fault location caused by misjudgment of a single factor; at the same time, by introducing a test device to simulate the function of the upper computer, the working status of the lower computer and related hardware links is further verified, enhancing the adaptability to complex communication failure scenarios, which can not only improve the accuracy of communication failure troubleshooting, avoid false alarms or data loss, but also reduce the manual intervention cost and maintenance time, ensuring the stable operation and equipment safety of the pumped-storage power station online monitoring system.

[0080] In another embodiment, after detecting whether the numerical display of the lower computer is normal, it further includes:

[0081] When the numerical display of the lower computer is abnormal, it is detected whether there is a fault in the sensor connected to the lower computer, the preamplifier in the lower computer, the acquisition board in the lower computer or the computer system of the lower computer, and a fault detection result is obtained; when the fault detection result indicates that there is a fault, the first fault processing information is output through the upper computer; the first fault processing information is used to indicate the processing of the fault detected in the fault detection result; when the numerical display of the lower computer is normal and there is still a communication failure between the upper computer and the lower computer, it returns to the step of detecting the network connectivity between the upper computer and the lower computer.

[0082] Among them, the preamplifier is a module in the lower computer, which is used to preprocess the signals collected by the sensor (such as amplification, filtering, etc.). The acquisition board is the core module in the lower computer, which is used to digitize the signals processed by the preamplifier (such as A / D conversion) and store or transmit them. The computer system of the lower computer is the main control unit in the lower computer, which is responsible for managing the data acquisition function, running application programs and communicating with the upper computer.

[0083] The first fault handling information includes a specific description of the detected fault. For example, it is detected that a certain component (such as a sensor, a preamplifier, an acquisition board, etc.) cannot work properly. The first fault handling information can be used to provide guidance for problem fixing. The first fault handling information may include the fault location (indicating whether it is a sensor, a preamplifier, an acquisition board or other module fault), and fault repair suggestions (such as replacing the damaged component, adjusting the configuration, removing the interference source, etc.). After detecting a specific fault, the host computer automatically outputs clear fault handling information, including the name and type of the faulty component and possible repair measures (such as replacing the sensor, checking the preamplifier circuit, reconfiguring the acquisition board, etc.), which can improve the fault handling efficiency.

[0084] In specific implementation, to detect whether there is a fault in the sensor connected to the lower computer, it can be to send a calibration command to the sensor and read the diagnostic information or health status information of the sensor, or to determine whether the output value of the sensor is within a reasonable range, or to input known data to the sensor using a built-in or external function signal generator and detect whether the response of the sensor is correct.

[0085] In specific implementation, to detect whether there is a fault in the preamplifier, it can be to compare the relationship between the original signal (input) of the sensor and the signal (output) processed by the preamplifier, detect whether the gain (amplification factor) or filtering parameters of the preamplifier are normal, and check whether there is distortion, noise or abnormal frequency components in the output signal of the preamplifier. For example, a standard signal (such as a sine wave with a known amplitude) can be input, and whether the output is consistent with the expected value can be compared.

[0086] In specific implementation, to detect whether there is a fault in the acquisition board in the lower computer, it can be to monitor the working status of each acquisition channel, including whether the A / D conversion module is working and whether the sampling rate is abnormal, or to collect a known signal (such as a signal generated by a function signal generator) and detect whether the sampling result meets the expectation.

[0087] In specific implementation, to detect whether there is a fault in the computer system of the lower computer, it can be to regularly send test data packets to verify the communication ability between the lower computer and the host computer or other devices, or to check whether the running processes are normal, whether the version and check value of the lower computer application program are correct, or to collect and analyze the logs of the operating system and application programs to detect abnormal events (such as crashing, communication interruption, etc.), or to check whether the storage device is running normally (such as read / write speed, file system integrity), and detect the CPU temperature, memory occupancy rate, network interface status, etc.

[0088] When the numerical display of the lower computer is normal but there is still a communication fault, it automatically returns to the network connectivity detection step to ensure that each fault point can be gradually located in complex scenarios (such as when there are multiple problems at the same time). It supports dynamic fallback logic, enhancing the robustness of the solution and avoiding missing other potential problems due to a single diagnostic error.

[0089] The technical solution of this embodiment provides an efficient hierarchical fault troubleshooting method. By gradually detecting the numerical display status of the lower computer, the module-level hardware status, network connectivity, and communication status, it realizes fast and accurate fault location and handling. First, check whether the numerical display of the lower computer is abnormal to quickly determine whether the fault occurs inside the lower computer. If the lower computer display is normal, the problem is located as a network fault. If the lower computer display is abnormal, further subdivide the fault source (sensor, preamplifier, acquisition board, computer system), avoiding disorderly fault troubleshooting and significantly shortening the troubleshooting time; accurately locate the fault and reduce the misdiagnosis rate by detecting whether each module (sensor, preamplifier, acquisition board, computer system) inside the lower computer is faulty and eliminating potential problems one by one. Through the combination of the numerical display status and the module detection results, the accuracy of fault location is ensured.

[0090] In another embodiment, after detecting the network connectivity between the upper computer and the lower computer, it further includes:

[0091] In the case of abnormal network connectivity, detect whether the Internet Protocol (IP) addresses of the upper computer and the lower computer conflict with the IP addresses of other devices in the local area network to obtain a conflict detection result; in the case where the conflict detection result indicates a conflict, change the IP addresses of the upper computer and the lower computer to IP addresses that do not conflict with other devices in the local area network; in the case where the conflict detection result indicates no conflict, output second fault handling information through the upper computer; the second fault handling information is used to indicate to gradually check whether the hardware wiring between the upper computer and the lower computer is wrongly connected or broken;

[0092] After detecting the network configuration of the upper computer and the lower computer, it further includes:

[0093] In the case of abnormal network configuration, update the gateway and subnet mask of the upper computer and the lower computer to the correct gateway and subnet mask; in the case where the network configuration is normal, network connectivity is normal, and there is still a communication fault between the upper computer and the lower computer, return to the step of simulating the function of the upper computer through a test device.

[0094] Among them, the Internet Protocol (IP) address is the unique identifier of a device in the network, used to identify the device and enable data communication. If two devices are set with the same IP address, it will cause communication failure.

[0095] The monitoring center controller can broadcast an Address Resolution Protocol (ARP) request within the local area network to which the host computer and the slave computer belong, check the Internet Protocol addresses of other devices, and compare whether the IP addresses of the host computer and the slave computer are repeated with the IP addresses of the devices within the local area network. If they are repeated, it is determined that there is a conflict, and then the conflicting IP addresses can be changed to unique non-conflicting IP addresses. After the update, the network connectivity can be retested.

[0096] When there is no IP address conflict, the troubleshooting guidance information output by the host computer, that is, the second fault handling information, is used to guide the step-by-step inspection of the hardware wiring between the host computer and the slave computer.

[0097] The hardware wiring between the host computer and the slave computer can be the physical lines (such as network cables, optical fibers, etc.) connecting the host computer and the slave computer, including intermediate devices (such as optical and electrical switches, fiber optic boxes). The incorrect connection of the hardware wiring can be that the line is connected to the wrong interface, and the breakage of the hardware wiring can be that the signal cannot be transmitted due to physical damage to the line.

[0098] The monitoring center controller can check whether it conforms to the network plan by comparing the gateway and subnet mask configurations of the host computer and the slave computer. If it does not conform, it is determined that the network configuration is abnormal, and the gateway and subnet mask of the host computer and the slave computer are updated to the correct gateway and subnet mask. After the update, the network connectivity is retested.

[0099] If the network configuration is normal and the network connectivity is also normal, but there is still a communication fault between the host computer and the slave computer, after troubleshooting the network configuration problem and the network connectivity problem, the next step can be to return to the step of simulating the function of the host computer through the test device.

[0100] The technical solution of this embodiment realizes accurate fault location and systematic troubleshooting logic through multi-level detection of network connectivity, IP conflict, network configuration, and hardware wiring; the automatic update of IP addresses, gateways, and subnet masks reduces manual intervention and improves the efficiency of fault handling; provides dynamic fallback logic in multiple fault scenarios to ensure that all problem points can be covered; outputs the second fault handling information to clarify the fault points and handling suggestions; and can handle multiple scenarios such as IP conflict, network configuration error, and hardware failure, which is suitable for complex local area network structures. The entire fault troubleshooting process is more efficient, accurate, and intelligent, and is suitable for application scenarios with high requirements for communication link stability such as pumped storage power stations.

[0101] In another embodiment, the function of the host computer is simulated by a test device, and the signal reception status between the test device and the slave computer is detected, including: when the test device is connected to the optical electric switch of the slave computer, the function of the host computer is simulated by the test device, and it is detected whether the test device can normally receive the signal of the slave computer to obtain the first signal reception status; when the first signal reception status indicates that the test device can normally receive the signal of the slave computer, connection replacement information is output by the host computer; the connection replacement information is used to indicate connecting the test device to the optical electric switch of the host computer; when the test device is connected to the optical electric switch of the host computer, the function of the host computer is simulated by the test device, and it is detected whether the test device can normally receive the signal of the slave computer to obtain the second signal reception status.

[0102] Among them, the first signal reception status may be the status of detecting whether the test device can normally receive the signal of the slave computer after the test device is directly connected to the slave computer through the optical electric switch of the slave computer. If the first signal reception status is normal, it can indicate that the slave computer and the optical electric switch of the slave computer are working properly; if the first signal reception status is abnormal, it can indicate that there is a fault in the slave computer or the optical electric switch of the slave computer.

[0103] Among them, the second signal reception status may be the status of detecting whether the signal of the slave computer can be normally received after the test device is indirectly connected to the slave computer through the optical electric switch of the host computer. If the second signal reception status is normal, it can indicate that the optical electric switch of the host computer and the entire communication link are normal; if the second signal reception status is abnormal, it can indicate that there is a problem with the optical electric switch of the host computer or its connection link.

[0104] Among them, the connection replacement information can be used to prompt the operator to change the connection mode of the test device, and switch the connection of the test device from the optical electric switch of the slave computer to the optical electric switch of the host computer.

[0105] The technical solution of this embodiment simulates the function of the host computer by a test device, and detects the signal reception status (the first signal reception status and the second signal reception status) with the slave computer in two stages, so as to gradually troubleshoot the communication problems between the host computer, the slave computer and the intermediate network device (such as the optical electric switch). The function of the host computer is gradually replaced by the test device, and the communication links of the optical electric switch of the slave computer and the optical electric switch of the host computer are respectively tested, and the fault range is gradually narrowed; when the first signal reception status is normal, it automatically prompts to change the connection to the optical electric switch of the host computer, improving the detection efficiency.

[0106] Further, in one of the embodiments, after obtaining the first signal reception state, it further includes: when the first signal reception state indicates that the test device cannot normally receive the signal from the lower computer, outputting third fault information through the upper computer; the third fault information is used to indicate to check and replace the network cable between the lower computer and the optical electric switch of the lower computer, as well as the optical electric switch of the lower computer; when the first signal reception state indicates that the test device can normally receive the signal from the lower computer, and there is still a communication fault between the upper computer and the lower computer, return to the step of outputting replacement connection information through the upper computer.

[0107] In a specific implementation, when the first signal reception state indicates that the test device cannot normally receive the signal from the lower computer, outputting third fault information through the upper computer, the third fault information indicates that the problem may occur in the lower computer or its optical electric switch and the network cable between the two, thereby limiting the fault range to the optical electric switch of the lower computer and the network cable between the lower computer and the optical electric switch of the lower computer, making the fault location more accurate. For example, if there is an abnormality in the network cable, the network cable needs to be replaced; if there is an abnormality in the optical electric switch of the lower computer, the optical electric switch of the lower computer needs to be replaced.

[0108] When the first signal reception state indicates that the test device can normally receive the signal from the lower computer, and there is still a communication fault between the upper computer and the lower computer, return to the step of outputting replacement connection information through the upper computer, switch the connection of the test device from the optical electric switch of the lower computer to the optical electric switch of the upper computer, continue to simulate the upper computer function, and detect the second signal reception state.

[0109] The technical solution of this embodiment directly connects the test device to the optical electric switch of the lower computer to determine whether the network cable and the optical electric switch between the lower computer and the optical electric switch are working properly. When the first signal reception state is normal, return to the step of outputting replacement connection information to further check the problems of the optical electric switch of the upper computer and its connection link, avoid a comprehensive inspection of the entire communication link, narrow the inspection range, and improve the positioning efficiency; when the test device can receive the signal but the upper computer and the lower computer still have abnormal communication, return to the step of outputting replacement connection information to check the problems of the optical electric switch of the upper computer or its link, avoid missing other potential faults due to a single detection result, and improve the comprehensiveness and reliability of troubleshooting.

[0110] Further, in one embodiment, the fault troubleshooting result of the on-line monitoring system of the pumped storage power station is determined according to the signal reception status, including: when the second signal reception status indicates that the test device cannot normally receive the signal from the lower computer, the fourth fault information is output by the upper computer; the fourth fault information is used to indicate whether the optical fiber between the upper computer and the lower computer is normal for inspection and replacement; when the second signal reception status indicates that the test device can normally receive the signal from the lower computer, the fifth fault information is output by the upper computer; the fifth fault information is used to indicate the inspection and replacement of the network cable between the upper computer and the optical electric switch of the upper computer, and the computer system of the upper computer; when the second signal reception status indicates that the test device can normally receive the lower computer, and there is still a communication fault between the upper computer and the lower computer, return to the step of detecting whether the numerical display of the lower computer is normal; when the second signal reception status indicates that the test device can normally receive the lower computer, and there is no communication fault between the upper computer and the lower computer, determine that the fault troubleshooting result of the on-line monitoring system of the pumped storage power station is the end of fault handling.

[0111] In specific implementation, the test device is connected to the upper computer optical electric switch to simulate the function of the upper computer. The test device receives the signal from the lower computer through the upper computer optical electric switch, and the recorded result is the second signal reception status.

[0112] When the second signal reception status indicates that the test device cannot normally receive the signal from the lower computer, the fourth fault information is output by the upper computer. The fourth fault information is used to indicate that the problem may occur in the optical fiber connection between the upper computer and the lower computer, and instruct the maintenance personnel to check whether the optical fiber connection between the upper computer and the lower computer is normal (such as breakage, wrong connection, signal attenuation, etc.).

[0113] Among them, checking whether the optical fiber between the upper computer and the lower computer is normal can be checked in three sections, including: checking the optical fiber from the upper computer optical fiber box to the upper computer switch. If the optical fiber is abnormal, this section of the optical fiber needs to be replaced; checking the optical fiber from the lower computer optical fiber box to the lower computer switch. If the optical fiber is abnormal, this section of the optical fiber needs to be replaced; checking the optical fiber from the upper computer optical fiber box to the lower computer optical fiber box. If the optical fiber is abnormal, this section of the optical fiber needs to be replaced.

[0114] When the second signal reception status indicates that the test device can receive the signal from the lower computer normally, the upper computer outputs the fifth fault message, which is used to indicate that the problem may occur in the network cable between the upper computer and the upper computer optical switch and the computer system of the upper computer. The problems of the computer system of the upper computer can include network card failure, network configuration error, driver exception, software crash, memory overload, storage unit damage, etc. The fifth fault message can guide the maintenance personnel to check whether the network cable is correctly connected, damaged or aged, check the hardware status of the upper computer (such as the working status of the network card), and test the network configuration of the upper computer operating system.

[0115] If the second signal reception status is normal and there is no communication fault between the upper computer and the lower computer, the entire fault troubleshooting process and solution can be recorded, and the further fault troubleshooting process can be terminated. The entire system troubleshooting is completed, and it is confirmed that there is no further fault.

[0116] If the second signal reception status is normal, but there is still a communication fault between the upper computer and the lower computer, it can return to the initial troubleshooting step, that is, the step of detecting whether the numerical display of the lower computer is normal, and conduct a re-troubleshooting.

[0117] The technical solution of this embodiment gradually narrows down the fault range to specific hardware (optical fiber, network cable, upper computer system) or communication links by analyzing the second signal reception status in stages, quickly troubleshooting various potential faults in complex communication links; dynamically adjusts the troubleshooting process according to different second signal reception statuses. If the test device cannot receive the signal, directly check the optical fiber link. If the test device receives the signal but there is still a problem with the upper computer communication, further check the network cable and the upper computer system; comprehensively check each link in the communication link, including the optical fiber link, network cable connection, hardware device and its configuration, to avoid missing potential problems and improve the accuracy of fault troubleshooting; if there is still a communication fault after multiple verifications, return to the previous step to re-analyze the numerical display of the lower computer to ensure full coverage of all possible faults in the system, and gradually confirm the final fault point through multi-layer verification to avoid misjudgment of single detection.
