The online monitoring system of a pumped-storage power station usually adopts a hierarchical distributed structure, generally consisting of a host computer unit, a data acquisition unit and its sensor unit.

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 communication faults between upper and lower computers of the online monitoring system of a pumped storage power station provided in the embodiment of the present application can be applied to the online monitoring system 100 of a pumped storage power station as shown in FIG1. ​​The online monitoring system 100 of a pumped storage power station may include a sensor 101, a lower computer data acquisition device 102, an optoelectronic switch 103 of the lower computer, an optical fiber box 104 of the lower computer, an optical fiber box 105 of the upper computer, an optoelectronic switch 106 of the upper computer, and an upper computer server 107. Among them, the sensor can be used to measure the parameters related to the stability of the unit, such as the swing of the main shaft, the vibration of the frame, and the pressure pulsation; the lower computer data acquisition equipment can be used to pre-process 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 status of the unit; the optoelectronic switch of the lower computer can be used to convert the various characteristic parameters processed by the lower computer from electrical signals to optical signals and then transmit them to the optoelectronic switch of the upper computer; the optical fiber box of the lower computer can be used to provide an optical fiber interface for the optoelectronic switch of the lower computer, and the optical fiber in the box is connected to the optical fiber box of the upper computer; the optical fiber box of the upper computer can be used to provide an optical fiber interface for the optoelectronic switch of the upper computer, and the optical fiber in the box is connected to the optical fiber box of the lower computer; the optoelectronic switch of the upper computer can be used to receive the optical signal containing various characteristic parameters transmitted by the optoelectronic switch of the lower computer, and at the same time convert the optical signal into an electrical signal and transmit it 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 forward data to transmit the characteristic parameters to other systems.

[0052] The online monitoring system of the pumped storage power station may also include a monitoring center controller 108, which may 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 the test equipment, and detects the signal receiving status between the test equipment and the lower computer; the test equipment is connected to the photoelectric 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 receiving status.

[0053] In an exemplary embodiment, as shown in FIG2 , a method for troubleshooting communication faults between upper and lower computers of an online monitoring system for a pumped storage power station is provided, and the method is described by taking the application of the method to the online monitoring system for a pumped storage power station in FIG1 as an example, including:

[0054] Step S202: in the case where there is a communication failure between the upper computer and the lower computer, detecting whether the numerical display of the lower 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 online monitoring system of a pumped storage power station, which is responsible for the monitoring, command issuance, data collection, processing and analysis, and user interaction of the entire system. The lower computer can be a device or controller directly connected to hardware such as sensors and actuators in the system, which can execute specific control instructions issued by the host computer, such as the output of switch signals, the adjustment of analog quantities, and the collection of data. For example, the host computer here can refer to the host computer server, and the lower computer here can refer to the lower computer data acquisition device.

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

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

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

[0059] Step S204, when the numerical value displayed on the lower computer is normal, the network connectivity between the upper computer and the lower computer is detected.

[0060] The network connectivity may refer to whether the upper computer and the lower computer can communicate normally through the physical link and the network protocol.

[0061] Exemplarily, the network connectivity between the upper computer and the lower computer can be tested by using the Packet Internet Groper (ping) command in the network communication to test the network connectivity between the upper computer and the lower computer. Specifically, the monitoring center controller can control the upper computer server to send a ping packet to the lower computer data acquisition device, and determine whether the ping packet 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 notification to the monitoring center controller. When the monitoring center controller receives the confirmation receipt notification within a preset time, 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 notification within the preset time, 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 host computer and the slave computer.

[0064] The network configuration may include the basic parameters and equipment required for the host and slave computers to participate in network communications, including Internet Protocol IP addresses, gateways, subnet masks, etc.

[0065] The gateway refers to the exit device for network devices (such as host or slave computers) to access other subnets or external networks, usually the address of a router or a layer 3 switch. If the host or slave 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 the network part and the host part, thereby determining the subnet range where the device is located. The subnet mask helps network devices determine whether the target address belongs to the same subnet. An incorrect subnet mask configuration may cause the device to be unable to identify other devices in the same subnet, affecting communication. For example, if the gateway is incorrectly configured, the network device cannot access other subnets or external networks, affecting data transmission and system functions; if the subnet mask is incorrectly configured, the host and slave computers may not be able to correctly determine whether they are in the same subnet due to incorrect subnet division, resulting in communication interruption or data forwarding failure.

[0067] Exemplarily, the network configuration of the upper computer and the lower computer is detected. The monitoring center controller can automatically obtain the network configuration parameters of the upper computer and the lower computer through a script, and can parse the network configuration parameters through regular expressions or matching tools, and compare them with 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, the test device simulates the function of the upper computer and detects the signal reception status between the test device and the lower computer.

[0069] The test equipment is connected to the photoelectric switch of the upper computer or the lower computer.

[0070] In a specific implementation, the test device can be a computer or notebook configured with the software of the host computer. Through the software of the host computer, the test device can establish a connection with the lower computer through the network protocol, send requests or receive data, and parse the data received from the lower computer and display or store it, so that it can play the role of the host computer and simulate the functions of the host computer. Therefore, by copying the software of the host computer to the test device and connecting the test device to the optical switch of the host computer or the lower computer, the functions of the host computer can be simulated through the test device.

[0071] For example, when the test device is connected to the optoelectronic switch of the lower computer, the test path is: the test device Optoelectronic switch of the lower computer Lower computer data acquisition equipment.

[0072] For example, when the test device is connected to the optoelectronic switch of the host computer, the test path is: the test device Host computer fiber optic box Lower computer fiber optic box Optoelectronic switch of the lower computer Lower computer data acquisition equipment.

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

[0074] In a 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. For example, if the test device cannot receive any signal sent by the lower computer, or the data received by the test device is incomplete, delayed, or frequently lost, it can be determined that the signal reception status between the test device and the lower computer is abnormal; if the above situation does not occur, it can be determined that the signal reception status between the test device and the lower computer is normal.

[0075] Step S210, determining the fault troubleshooting result of the pumped storage power station online monitoring system according to the signal receiving status.

[0076] In the previous steps, such as numerical display check, network connectivity check, and network configuration verification, the possible fault range has been gradually narrowed down. The test equipment simulates the upper computer function, detects the signal reception status between the test equipment and the lower computer, and finally obtains the accurate location and solution of the fault through the signal reception status.

[0077] For example, when the test device is connected to the optoelectronic switch of the lower computer, if the signal receiving state is abnormal, it can be determined that the "test device Optoelectronic switch of the lower computer There is a problem with the communication link of the lower computer data acquisition device or a problem with the device in it; when the test equipment is connected to the photoelectric switch of the upper computer, if the signal receiving status is abnormal, it can be determined that the "test equipment" Host computer fiber optic box Lower computer fiber optic box Optoelectronic switch of the lower computer There is a problem with the communication link of the "lower computer data acquisition device" or a problem with the device in it.

[0078] Assuming that the above problems have been solved, and the signal reception status is normal when the test equipment is connected to the optoelectronic switch of the lower computer and when the test equipment is connected to the optoelectronic switch of the upper computer, it is possible to detect again whether there is still a communication failure between the upper computer and the lower computer. If there is no communication failure, it is determined that the troubleshooting results of the pumped-storage power station online monitoring system have been completed; if there is still a communication failure, a serious fault notification can be directly sent to notify manual processing.

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

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

[0081] When the numerical value displayed by the lower computer is abnormal, detect 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 obtain the fault detection result; when the fault detection result indicates the existence of a fault, output the first fault processing information 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 value displayed by the lower computer is normal and there is still a communication fault between the upper computer and the lower computer, return 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 pre-process 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 (such as A / D conversion) and store or transmit the signals processed by the preamplifier. The computer system of the lower computer is the main control unit in the lower computer, responsible for managing data acquisition functions, running applications 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 (sensor, preamplifier, acquisition board, etc.) cannot work properly. The first fault handling information can be used to provide guidance for problem repair. The first fault handling information can include the fault location (indicating that it is a sensor, preamplifier, acquisition board or other module fault), fault repair suggestions (replace damaged parts, adjust configuration, remove interference sources, 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 efficiency of fault handling.

[0084] In a specific implementation, to detect whether a sensor connected to the lower computer has a fault, a calibration command can be sent to the sensor and the diagnostic information or health status information of the sensor can be read. Alternatively, the output value of the sensor can be determined to be within a reasonable range. Alternatively, a built-in or external function signal generator can be used to input known data into the sensor to detect whether the sensor's response is correct.

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

[0086] In the 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, whether the sampling rate is abnormal, or to collect known signals (such as signals generated by a function signal generator) to detect whether the sampling results meet expectations.

[0087] In a specific implementation, to detect whether there is a fault in the computer system of the lower computer, test data packets can be sent regularly to verify the communication capability of the lower computer with the upper computer or other devices, or to check whether the running process is normal, whether the version and checksum of the lower computer application are correct, or to collect and analyze the logs of the operating system and application, detect abnormal events (such as freezes, communication interruptions, etc.), or check whether the storage device is operating normally (such as read / write speed, file system integrity), detect CPU temperature, memory usage, network interface status, etc.

[0088] When the lower computer values ​​are normal but there is still a communication failure, 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 multiple problems exist at the same time). It supports dynamic fallback logic, which enhances the robustness of the solution and avoids missing other potential problems due to a single diagnostic error.

[0089] The technical solution of this embodiment provides an efficient hierarchical fault troubleshooting method, which realizes fast and accurate fault location and processing by gradually detecting the numerical display status of the lower computer, the module-level hardware status, the network connectivity and the communication status. First, check whether the numerical display of the lower computer is abnormal, and quickly determine whether the fault occurs inside the lower computer. If the display of the lower computer is normal, the problem is located as a network fault. If the display of the lower computer is abnormal, the fault source (sensor, preamplifier, acquisition board, computer system) is further subdivided to avoid disorderly fault troubleshooting and significantly shorten the troubleshooting time; accurately locate the fault, reduce the misdiagnosis rate, detect whether each module in the lower computer (sensor, preamplifier, acquisition board, computer system) is faulty, eliminate potential problems one by one, and ensure the accuracy of fault location by combining the numerical display status with the module detection results.

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

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

[0092] After checking the network configuration of the host and slave computers, it also includes:

[0093] In 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 case of normal network configuration, normal network connectivity, and communication failure still exists between the upper computer and the lower computer, return to the step of simulating the function of the upper computer through the test equipment.

[0094] The Internet Protocol address (IP) is the unique identifier of a device in the network, which is used to identify the device and realize data communication. If two devices are set with the same IP address, communication will fail.

[0095] The monitoring center controller can broadcast an Address Resolution Protocol (ARP) request in the local area network to which the upper and lower computers belong, check the Internet Protocol addresses of other devices, and compare the IP addresses of the upper and lower computers with the IP addresses of the devices in the local area network to see if they are repeated. If they are repeated, it is determined that there is a conflict, and the conflicting IP address can be changed to a unique IP address that does not conflict. After the update, the network connectivity can be retested.

[0096] When there is no conflict in the IP addresses, the troubleshooting guidance information output by the upper computer, namely the second troubleshooting information, is used to guide the step-by-step inspection of the hardware connection between the upper computer and the lower computer.

[0097] The hardware wiring between the upper computer and the lower computer can be the physical line connecting the upper computer and the lower computer (such as a network cable, optical fiber, etc.), including intermediate equipment (such as an optoelectronic switch, optical fiber box). A wrong hardware wiring connection can be caused by connecting the line to the wrong interface. A broken hardware wiring can be caused by physical damage to the line, resulting in the inability to transmit signals.

[0098] The monitoring center controller can check whether the gateway and subnet mask configurations of the upper and lower computers comply with the network plan by comparing them. If not, it determines that the network configuration is abnormal, and updates the gateway and subnet mask of the upper and lower computers to the correct gateway and subnet mask, and retests the network connectivity after the update.

[0099] If the network configuration is normal and the network connectivity is normal, but there is still a communication failure between the upper and lower computers, the network configuration problem and the network connectivity problem have been checked, and the next step can be to return to the step of simulating the function of the upper 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 address, gateway and subnet mask reduces manual intervention and improves fault handling efficiency; dynamic fallback logic is provided in various fault scenarios to ensure that all problem points can be covered; the second fault handling information is output to clarify the fault point and handling suggestions; it can deal with various scenarios such as IP conflict, network configuration error and hardware failure, and is suitable for complex LAN structures. The entire troubleshooting process is more efficient, accurate and intelligent, and is suitable for application scenarios such as pumped storage power stations that have high requirements for communication link stability.

[0101] In another embodiment, 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, including: when the test device is connected to the optoelectronic switch of the lower computer, the function of the upper computer is simulated by the test device, and whether the test device can normally receive the signal of the lower computer is detected to obtain a first signal reception status; when the first signal reception status represents that the test device can normally receive the signal of the lower computer, the connection replacement information is output by the upper computer; the connection replacement information is used to indicate that the test device is connected to the optoelectronic switch of the upper computer; when the test device is connected to the optoelectronic switch of the upper computer, the function of the upper computer is simulated by the test device, and whether the test device can normally receive the signal of the lower computer is detected to obtain a second signal reception status.

[0102] The first signal receiving state may be a state in which the test device is directly connected to the lower computer through the lower computer optical switch to detect whether the test device can normally receive the signal of the lower computer. If the first signal receiving state is normal, it can be said that the lower computer and the lower computer optical switch are working normally; if the first signal receiving state is abnormal, it can be said that the lower computer or the lower computer optical switch has a fault.

[0103] The second signal receiving state can be a state in which the test equipment detects whether it can normally receive the signal of the lower computer after being indirectly connected to the lower computer through the upper computer optical switch. If the second signal receiving state is normal, it can be said that the upper computer optical switch and the entire communication link are normal; if the second signal receiving state is abnormal, it can be said that there is a problem with the upper computer optical switch or its connection link.

[0104] The connection change information may be used to prompt the operator to change the connection mode of the test equipment, and switch the connection of the test equipment from the lower computer optical switch to the upper computer optical switch.

[0105] The technical solution of this embodiment simulates the function of the upper computer through the test equipment, and detects the signal receiving state of the lower computer in two stages (the first signal receiving state and the second signal receiving state), so as to gradually troubleshoot the communication problems between the upper computer, the lower computer and the intermediate network equipment (such as the optoelectronic switch). The test equipment gradually replaces the function of the upper computer, respectively tests the communication links of the optoelectronic switch of the lower computer and the optoelectronic switch of the upper computer, and gradually reduces the scope of the fault; when the first signal receiving state is normal, it automatically prompts to change the connection to the optoelectronic switch of the upper computer, so as to improve the detection efficiency.

[0106] Furthermore, in one of the embodiments, after obtaining the first signal reception state, it also includes: when the first signal reception state indicates that the test device cannot normally receive the signal of the lower computer, outputting third fault information through the upper computer; the third fault information is used to indicate checking and replacing the network cable between the lower computer and the optoelectronic switch of the lower computer, and the optoelectronic switch of the lower computer; when the first signal reception state indicates that the test device can normally receive the signal of the lower computer, and there is still a communication failure between the upper computer and the lower computer, returning to the step of outputting the connection replacement information through the upper computer.

[0107] In a specific implementation, when the first signal receiving state indicates that the test device cannot normally receive the signal of the lower computer, the upper computer outputs the third fault information, which indicates that the problem may occur in the lower computer or its optoelectronic switch and the network cable between the two, thereby limiting the fault range to the optoelectronic switch of the lower computer and the network cable between the optoelectronic switches 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, and if there is an abnormality in the optoelectronic switch of the lower computer, the optoelectronic switch of the lower computer needs to be replaced.

[0108] When the first signal receiving state indicates that the test device can normally receive the signal from the lower computer and there is still a communication failure between the upper computer and the lower computer, return to the step of changing the connection information through the upper computer output, switch the connection of the test device from the lower computer optoelectronic switch to the upper computer optoelectronic switch, continue to simulate the upper computer function, and detect the second signal receiving state.

[0109] The technical solution of this embodiment is to directly connect the lower computer optoelectronic switch through the test equipment to determine whether the network cable and the optoelectronic switch between the lower computer and the optoelectronic switch are working properly. When the first signal reception status is normal, the step of replacing the connection information is returned to further check the problems of the upper computer optoelectronic switch and its connection link, avoid comprehensive inspection of the entire communication link, narrow the scope of investigation, and improve positioning efficiency; when the test equipment can receive the signal but the upper computer and the lower computer still communicate abnormally, the step of replacing the connection information is returned to check the problems of the upper computer optoelectronic switch 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 of the embodiments, the troubleshooting result of the online monitoring system of the pumped-storage power station is determined according to the signal receiving status, including: when the second signal receiving status indicates that the test equipment cannot normally receive the signal of the lower computer, the fourth fault information is output through the upper computer; the fourth fault information is used to indicate whether the inspection and replacement of the optical fiber between the upper computer and the lower computer is normal; when the second signal receiving status indicates that the test equipment can normally receive the signal of the lower computer, the fifth fault information is output through 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 optoelectronic switch of the upper computer, and the computer system of the upper computer; when the second signal receiving status indicates that the test equipment can normally receive the lower computer, and there is still a communication failure 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 receiving status indicates that the test equipment can normally receive the lower computer, and there is no communication failure between the upper computer and the lower computer, determine that the troubleshooting result of the online monitoring system of the pumped-storage power station is that the fault processing is completed.

[0111] In a specific implementation, the test device is connected to the upper computer optoelectronic switch to simulate the upper computer function. The test device receives a signal from the lower computer through the upper computer optoelectronic switch and records the result as the second signal receiving state.

[0112] When the second signal receiving state indicates that the test equipment cannot normally receive the signal from the lower computer, the upper computer outputs fourth fault information, which 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 divided into 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, the optical fiber section 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, the optical fiber section 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, the optical fiber section needs to be replaced.

[0114] When the second signal receiving state indicates that the test equipment can normally receive the signal of the lower computer, the upper computer outputs the fifth fault information, which is used to indicate that the problem may occur in the network cable between the upper computer and the upper computer optoelectronic switch and the computer system of the upper computer. The problem of the computer system of the upper computer may include network card failure, network configuration error, driver abnormality, software crash, memory overload, storage unit damage, etc. The fifth fault information can let the maintenance personnel know whether the network cable is connected correctly, 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 receiving state is normal and there is no communication failure between the upper computer and the lower computer, the entire troubleshooting process and solution can be recorded, and further troubleshooting procedures are terminated. The entire system troubleshooting is completed and it is confirmed that there are no further faults.

[0116] If the second signal receiving state is normal, but there is still a communication failure between the upper computer and the lower computer, you can return to the initial troubleshooting step, that is, the step of detecting whether the numerical display of the lower computer is normal, and re-check.

[0117] The technical solution of this embodiment analyzes the second signal reception status in stages, gradually narrows the fault scope to specific hardware (optical fiber, network cable, host computer system) or communication link, and quickly troubleshoots various potential faults in complex communication links; dynamically adjusts the troubleshooting process for different second signal reception states. 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 host computer communication, further check the network cable and the host computer system; comprehensively check each link in the communication link, including the optical fiber link, network cable connection, hardware equipment and its configuration, to avoid missing potential problems and improve the accuracy of troubleshooting; if the communication failure still exists after multiple verifications, return to the previous step to re-analyze the lower computer value display to ensure that all possible faults in the system are fully covered, and gradually confirm the final fault point through multi-layer verification to avoid misjudgment of a single detection.
