[0003] Currently, for the health diagnosis of the safety-class DCS of a nuclear power plant, it usually relies on the self-diagnosis measures of the system itself, including diagnosing and analyzing components such as boards, communication links, and power supplies and giving alarms. In addition, for the health diagnosis of the internal environment of the cabinet itself, it is mainly the detection of over-temperature in the cabinet. And currently, only the on / off of the door light and the indicator lights of the boards are relied on to judge the fault information of the system.

[0004] However, in the traditional diagnosis method, the diagnostic data for the health diagnosis of the internal environment of the cabinet itself is relatively single, which cannot provide sufficient data support for the health diagnosis of the cabinet environment and cannot provide effective and detailed cabinet health status information. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] The safety-class DCS is the core system to ensure the integrity of the three major safety barriers of nuclear power plants. It can perform emergency shutdown operations in the event of an accident to ensure the safety of the reactor, the environment and the public. As an important part of the safety-class DCS, the self-diagnosis function is the "health guard" for its stable and reliable operation and is crucial for the safety of the system. Traditional health diagnosis mainly focuses on self-diagnosis measures within the system, such as diagnosing and analyzing key components such as boards, communication links, and power supplies and giving fault alarms. However, these traditional methods have obvious deficiencies in detecting the cabinet environmental status and are difficult to comprehensively cover the potential risks of the system operating environment.

[0035] Nuclear power plants are generally built along the coast, where the temperature, humidity, salinity and dustiness change greatly. Too high temperature may cause overheating and damage of electronic components inside the cabinet, thus seriously affecting the stability of the system; too high humidity may cause a short-circuit risk; excessive salinity will accelerate the corrosion of metal components, and foreign matters such as dust accumulation during the transportation, assembly and maintenance of the cabinet will cause poor heat dissipation and circuit failures.

[0036] Moreover, in traditional diagnosis methods, digital input / output (DI) alarm information is usually used and transmitted to the main control room through the network for remote display. The local display function can only rely on the on / off control of the door light in series with some fault conditions and the board indicator lights to judge the fault information of the system. The cabinets of the safety-class DCS are in a closed state during normal operation, and it is difficult for operation and maintenance personnel to detect the environmental changes inside the cabinet in a timely manner. And relying only on the digital input / output (DI) alarm information, the remote main control room cannot quickly obtain comprehensive cabinet health status information, resulting in reduced system operation and maintenance efficiency and increased potential safety hazards.

[0037] The health diagnosis of the relevant safety-class DCS system mainly relies on the self-diagnosis of the system, and reference can be made to Figure 1 , Figure 1 For the schematic diagram of self-diagnosis provided by the related technology, according to the degree of influence on the functions of the control station, system failures can be divided into the following three levels: Input / Output (I / O) warning means that part or all of the I / O acquisition or output functions fail, but the data processing and communication functions of the control station are not affected; Alarm means that part or all of the communication functions fail, but the data processing function of the control station is not affected; Failure means that the entire control station fails and can no longer execute its functions. The above self-diagnosis process mainly targets the anomalies of the components of the instrument control system itself, specifically including abnormal device communication, abnormal data processing, I / O over-range, abnormal breaker status, abnormal power supply status, abnormal fan status, etc. In addition, during the above self-diagnosis process, the detection of the internal environment of the cabinet mainly focuses on the detection of the over-limit temperature inside the cabinet. For the above abnormal signals, through the control station, they can be aggregated into three digital quantities of I / O Warning, Alarm, and Failure for remote alarm display. At the same time, alarm display can be carried out through the cabinet door lights and board card indicator lights on the local side.

[0038] However, in the traditional diagnosis method, the diagnostic data for the health diagnosis of the internal environment of the cabinet itself is relatively single, which cannot provide sufficient data support for the health diagnosis of the cabinet environment and cannot provide effective and detailed information on the health status of the cabinet.

[0039] Based on this, to solve the above problems, in the cabinet health diagnosis system provided in the embodiments of the present application, the system is deployed in the nuclear power plant safety-class DCS. The system includes a local display module, an environmental detection sensor module, a cabinet detection module, and a remote display module. The environmental detection sensor module is connected to the cabinet detection module, and the cabinet detection module is respectively connected to the local display module and the remote display module. Among them, the environmental detection sensor module is used to collect the internal environmental parameters of the cabinet and send the environmental parameters to the cabinet detection module. The cabinet detection module is used to receive the environmental parameters and the detection data in the cabinet, and process them based on the environmental parameters and the detection data to obtain the cabinet equipment health parameters. It can be seen that through the environmental detection sensor module, richer environmental parameters can be collected from the inside of the cabinet. Further, through the cabinet detection module, the received environmental parameters and the detection data in the cabinet can be processed to obtain the cabinet equipment health parameters for reflecting the health status information of the cabinet equipment, thereby providing sufficient data support for the health diagnosis of the cabinet environment. Further, the local display module is used to display the cabinet equipment health parameters corresponding to multiple cabinets in the same room, and the remote display module is used to display the cabinet equipment health parameters corresponding to multiple cabinets in different rooms, so that more effective and detailed cabinet health status information can be provided through the local display module and the remote display module.

[0040] The following will combine the accompanying drawings and illustrate the specific implementation manners of the cabinet health diagnosis system, method, and related devices in the embodiments of the present application through examples.

[0041] See Figure 2 , Figure 2 is a schematic diagram of a cabinet health diagnosis system provided in the embodiments of the present application. The system is deployed in the nuclear power plant safety-class DCS. Combining Figure 2 shown, it may specifically include: an environmental detection sensor module 201, a cabinet detection module 202, a local display module 203, and a remote display module 204. The environmental detection sensor module 201 is connected to the cabinet detection module 202, and the cabinet detection module 202 is respectively connected to the local display module 203 and the remote display module 204.

[0042] Exemplarily, the data transmission between the environmental detection sensor module 201 and the cabinet detection module 202 can adopt a hard-wired form, the data transmission between the cabinet detection module 202 and the local display module 203 can adopt a communication method, and the data transmission between the cabinet detection module 202 and the remote display module 204 can adopt a communication method.

[0043] The environmental detection sensor module 201 is used to collect the environmental parameters inside the cabinet and send the environmental parameters to the cabinet detection module 202. The environmental parameters inside the cabinet refer to the parameters used to describe the environment inside the cabinet. For example, the environmental parameters may include, but are not limited to, temperature parameters, humidity parameters, salinity parameters, dust parameters, etc. The environmental detection sensor module 201 and the cabinet detection module 202 are installed inside each cabinet.

[0044] As an example, the environmental detection sensor module 201 includes a temperature sensor module, a humidity sensor module, a salinity sensor module, and a dust sensor module. For example, reference may be made to Figure 3 , Figure 3 which is a deployment schematic diagram of the environmental detection sensor module provided by the embodiment of the present application and can achieve targeted deployment inside the cabinet. The temperature sensor module is used to collect the temperature parameters inside the cabinet and send the temperature parameters to the cabinet detection module 202. As Figure 3 shown, the temperature sensor module can be installed near the main heat sources inside the cabinet (such as high-power electronic components and power modules, etc.) and at the key nodes of the ventilation channels. The humidity sensor module is used to collect the humidity parameters inside the cabinet and send the humidity parameters to the cabinet detection module 202. As Figure 3 shown, the humidity sensor module can be installed in a relatively stable and representative area in the middle of the cabinet where the air circulates. The salinity sensor module is used to collect the salinity parameters inside the cabinet and send the salinity parameters to the cabinet detection module 202. As Figure 3 shown, the salinity sensor module can be installed near the air inlet of the cabinet and in the area where the internal metal components are relatively dense. The dust sensor module is used to collect the dust parameters inside the cabinet and send the dust parameters to the cabinet detection module 202. As Figure 3 shown, the dust sensor module can be installed near the air outlet of the cabinet to facilitate the effective detection of the accumulation degree of dust inside the cabinet. In this way, in the present application, not only the temperature can be detected, but also the salinity, humidity, and dust accumulation degree inside the cabinet can be detected, which helps to perform a more accurate health diagnosis on the cabinet based on the rich environmental parameters collected.

[0045] The cabinet detection module 202 is configured to receive environmental parameters and detection data inside the cabinet, process them based on the environmental parameters and the detection data, and obtain the health parameters of the cabinet equipment. The detection data inside the cabinet refers to the data used to characterize whether the inside of the cabinet is operating normally. The detection data may include, but is not limited to, the cabinet door state, the breaker state, the fan state, I / O Warning, Alarm, and Failure alarm signals, etc. The health parameters of the cabinet equipment refer to the parameters used to reflect the health state of the cabinet. For example, the health parameters of the cabinet equipment may include, but are not limited to, the temperature, salinity, humidity, dust accumulation degree, cabinet door state, breaker state, fan state, I / O Warning, Alarm, and Failure alarm signals inside the cabinet, etc. It should be understood that the environmental parameters and the detection data inside the cabinet are analog signals or digital signals, and the digital-format health parameters of the cabinet equipment can be obtained only after being processed by the cabinet detection module 202.

[0046] As an example, the cabinet detection module 202 includes a controller, an input / output (I / O) terminal module, and a communication serial port. For example, the I / O terminal module can adopt a modular structure design and be installed and fixed in the standard 35-millimeter (mm) German standard DIN rail manner, and dissipate heat by natural ventilation. The I / O terminal module is used to receive environmental parameters and detection data inside the cabinet. Specifically, the analog input (AI) acquisition channels in the I / O terminal module can acquire environmental parameters, such as analog quantity parameters like temperature parameters, humidity parameters, salinity parameters, and dust parameters, and the digital input (DI) acquisition channels can acquire the cabinet door state, the breaker state, the fan state, I / O Warning, Alarm, and Failure alarm signals. The digital output (DO) signal can connect the fault signal processed by the controller to the cabinet lamp to play a role in alarm prompting.

[0047] The controller is used to process based on the environmental parameters and the detection data. For example, the collected analog quantity signal can be conditioned and converted into a voltage signal, and then through filtering and analog-to-digital (A / D) conversion, it is sent to the controller for data processing, such as performing calculations, calibrations, and compensations on the converted signal, etc., and the health parameters of the cabinet equipment can be obtained.

[0048] The communication serial port is used to send the health parameters of the cabinet equipment to the local display module 203 and the remote display module 204 through a preset communication method, such as the Modbus communication method. Refer to Figure 4 , Figure 4 is the structural schematic diagram of the cabinet detection module provided by the embodiment of the present application. As Figure 4As shown in the figure, the cabinet detection module includes 2 communication serial ports, which support providing the health parameters of cabinet devices to a third-party interface through the Modbus communication method. The cabinet detection module includes 2 four-wire RTD signals and 6 current (4 - 20 mA) or voltage (1 - 5 V) signals. The outside is connected to the output contacts of the environmental detection sensor module through hard wiring, and the inside is connected to the controller in the cabinet detection module. The cabinet detection module includes 16 dry contact DI signals, which can be sent to the controller through opto-isolation for data processing. The query voltage of the input signal is 24 volts direct current (VDC), and the query voltage can be provided by the internal power supply of the cabinet detection module without an external query power supply. The cabinet detection module also includes 2 DO signals (1 active and 1 passive), and the controller can output alarm information through a solid-state relay. The query power supply of the active DO is provided by the internal power supply of the cabinet detection module, and the query power supply of the passive DO is provided by an external power supply.

[0049] The local display module 203 is used to display the health parameters of cabinet devices corresponding to multiple cabinets in the same room. The local display module 203 can be a touch display screen, which can be connected to the cabinet detection module 202 through a serial port and communicate through the Modbus protocol to display the health parameters of cabinet devices. As Figure 5 shown, Figure 5 is a schematic structural diagram of the local display module provided by an embodiment of the present application. If multiple cabinets are arranged in a room, a cabinet detection module 202 is installed on each cabinet. The cabinet detection modules 202 corresponding to each cabinet in the same room can be connected to the local display module 203 in a parallel manner. After receiving the health parameters of cabinet devices sent by each cabinet detection module 202 in the same room, the local display module 203 can display the health parameters of cabinet devices corresponding to multiple cabinets in the same room through the local display module 203, so as to facilitate the operation and maintenance personnel to intuitively obtain the health status information of all cabinets in the same room.

[0050] In addition, the local display module 203 also includes a display program for receiving the health parameters of cabinet devices, converting them into an intuitive and vivid graphical interface and digital display content, and storing the data. Refer to Figure 6 , Figure 6Schematic diagram of the interface for the in-situ display module provided in the embodiments of the present application to display the health parameters of cabinet equipment. For example, the health parameters of cabinet equipment such as temperature, humidity, salinity, dust, etc. can be displayed in the form of a real-time curve to show the change trend over time. Moreover, alarm prompt information can be marked with colors (e.g., green indicates normal, yellow indicates mild over-standard, and red indicates severe over-standard). The dust concentration value can also be displayed in the form of a dial, and the health parameters of the cabinet equipment displayed can be stored. The in-situ display module 203 also includes simple operation buttons, and maintenance personnel can switch the display interface, view historical data records, and set some basic alarm thresholds through the buttons, etc.

[0051] The remote display module 204 is used to display the health parameters of the cabinet equipment corresponding to multiple cabinets in different rooms. As an example, the remote display module includes a communication network, a data communication module, and a human-machine interface module. Reference can be made to Figure 7 , Figure 7 Schematic diagram of the structure of the remote display module provided in the embodiments of the present application. The communication network is used to send the health parameters of the cabinet equipment corresponding to multiple cabinets in different rooms to the data communication module through a preset communication method, such as the serial communication protocol Modbus RTU. The cabinet detection modules 202 in the same room are connected in parallel, and each room can output 1 communication interface to send the collected health parameters of the cabinet equipment to the data communication module through Modbus RTU. The data communication module is used to forward the health parameters of the cabinet equipment corresponding to multiple cabinets in different rooms to the human-machine interface module. The human-machine interface module is used to receive and display the health parameters of the cabinet equipment corresponding to multiple cabinets in different rooms.

[0052] In terms of data display, the human-machine interface module can receive and analyze the health parameters of cabinet equipment through the main control room (such as the general control room of a nuclear power plant, where the operation of all equipment in the nuclear power plant can be detected), and can also convert the health parameters of cabinet equipment into graphical interface and digital display content to associate and display the health parameters of cabinet equipment corresponding to multiple cabinets in different rooms. For example, the health parameters of cabinet equipment corresponding to multiple cabinets in each room can be associated and displayed. For example, the abnormal conditions of the health parameters of cabinet equipment can be indicated by dynamically changing colors or flashing effects (such as green indicating normal, yellow indicating slightly exceeding the standard, and red indicating seriously exceeding the standard). The historical data trend chart of the health parameters of cabinet equipment can also be drawn with the time axis as the abscissa, which is convenient for operation and maintenance personnel to analyze the parameter change rules based on the historical data trend chart. The real-time data, historical data statistics, and fault alarm records of each sensor module can also be listed in tabular form. In this way, through the above methods, it is convenient for the main control room to directly obtain the health parameters of cabinet equipment of all cabinets, optimize the information received by the main control room, which helps to better detect and manage the safety-class DCS system at the overall level, and further improves the safety and reliability of the operation of the entire nuclear power plant's I&C system and optimizes the scientific nature of operation and maintenance decisions.

[0053] In addition, the main control room in the human-machine interface module can also perform fault diagnosis on the health parameters of cabinet equipment corresponding to multiple cabinets in different rooms received through a fault diagnosis algorithm to achieve the health diagnosis of the safety-class DCS system, and thus obtain the diagnosis results. The diagnosis results are used to indicate whether the cabinet is in a healthy state. For example, the fault diagnosis algorithm can perform fault diagnosis on the health parameters of cabinet equipment according to the healthy threshold range. If the health parameters of cabinet equipment are within the healthy threshold range, it can be considered that the current cabinet is in a healthy state. At the same time, preventive maintenance prompts can also be given according to the health parameters of cabinet equipment close to the healthy threshold range, such as displaying preventive prompt pop-ups. If the health parameters of cabinet equipment are not within the healthy threshold range, it can be considered that the current cabinet is not in a healthy state, and maintenance prompts can be given according to the health parameters of cabinet equipment not within the healthy threshold range, such as displaying alarm pop-ups.

[0054] Finally, refer to Figure 8 , Figure 8This is a schematic structural diagram of the cabinet health diagnosis system provided by the embodiments of the present application. An environmental detection sensor module and a cabinet detection module are installed inside each cabinet. The environmental parameters inside the cabinet can be collected through the environmental detection sensor module. Then, they can be transmitted through the AI / DI channels of the input / output terminal module in the cabinet detection module. The controller in the cabinet detection module can process the received environmental parameters and detection data to obtain the cabinet equipment health parameters. If multiple cabinets are arranged in the same room, the cabinet detection modules corresponding to each cabinet can be connected in parallel to send the aggregated cabinet equipment health parameters corresponding to multiple cabinets in the same room to the local display module for display. Moreover, the cabinet equipment health parameters corresponding to multiple cabinets in different rooms can also be sent to the remote display module to display the cabinet equipment health parameters corresponding to multiple cabinets in different rooms through the remote display module. In addition, the cabinet lights can be lit for alarm prompts, and the cabinet detection module and the cabinet lights can be connected by hard wiring.

[0055] Thus, through the local display module and the remote display module, it can help the operation and maintenance personnel no longer rely on simple door lights for judgment and directly view the detailed cabinet equipment health parameters, thereby improving the operation and maintenance efficiency of the safety-class DCS system and reducing the potential safety hazards of the equipment.

[0056] The above is a cabinet health diagnosis system provided by the embodiments of the present application. This system is deployed in the safety-class DCS of a nuclear power plant. The system includes a local display module, an environmental detection sensor module, a cabinet detection module, and a remote display module. The environmental detection sensor module is connected to the cabinet detection module, and the cabinet detection module is respectively connected to the local display module and the remote display module. Among them, the environmental detection sensor module is used to collect the environmental parameters inside the cabinet and send the environmental parameters to the cabinet detection module. The cabinet detection module is used to receive the environmental parameters and the detection data inside the cabinet, process them based on the environmental parameters and the detection data, and obtain the cabinet equipment health parameters. It can be seen that through the environmental detection sensor module, richer environmental parameters can be collected from inside the cabinet. Further, through the cabinet detection module, the received environmental parameters and the detection data inside the cabinet can be processed to obtain the cabinet equipment health parameters used to reflect the health status information of the cabinet equipment, thus providing sufficient data support for the health diagnosis of the cabinet environment. Further, the local display module is used to display the cabinet equipment health parameters corresponding to multiple cabinets in the same room, and the remote display module is used to display the cabinet equipment health parameters corresponding to multiple cabinets in different rooms, so that more effective and detailed cabinet health status information can be provided through the local display module and the remote display module.
