[0002] In nuclear power plants, control cabinets such as nuclear instrument control cabinets, DCS control cabinets, and emergency diesel generator control cabinets are important equipment involved in controlling the stable operation of the units. Hard wiring (i.e. cables) is usually used to achieve communication connections between control cabinets. In order to ensure the stable operation of nuclear power plants, the reliability of hard wiring needs to be tested regularly.

[0003] At present, the hard wiring is mainly tested by manual marking. The specific process is: 1. Manually check and find the hard wiring signals between cabinets that need to be verified; 2. Identify and find the sender and receiver of the hard wiring signals between cabinets that need to be verified; 3. Use tools to test whether the electrical performance of the hard wiring is normal. This method requires the cooperation of multiple people, and each signal takes about 5 minutes to complete the test. The test efficiency is low and cannot meet the test requirements of a large number of hard wiring signals, which greatly increases the operation and maintenance costs of nuclear power plants.

[0045] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0046] It should be noted that the flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor do they have to be executed in the order described. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0047] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0048] Figure 1The present invention is a flowchart of a method for testing hard-wired signals between cabinets in a nuclear power plant in some embodiments of the present invention, which can significantly improve the test efficiency of hard-wired signals. The method for testing hard-wired signals between cabinets in a nuclear power plant may include step S10, step S20 and step S30.

[0049] Step S10 includes: obtaining a test point list, wherein the test point list includes a number of signals to be tested transmitted between different control cabinets, as well as information about the sender control cabinet, the receiver control cabinet, and signal function information of each signal to be tested.

[0050] In some embodiments, by performing Figure 2 Steps S101, S102 and S103 are shown to determine a test point list.

[0051] Step S101 includes: obtaining the signal generation log of each control cabinet. This step can be achieved by communicating with each control cabinet (such as through a local area network) to obtain the signal generation log corresponding to each control cabinet. Among them, the signal generation log includes multiple hard-wired signals transmitted between each control cabinet, as well as the receiving control cabinet information, sending control cabinet information, signal name and signal history change record of each hard-wired signal. It should be noted that the receiving control cabinet information of the hard-wired signal includes the name of the control cabinet that receives the hard-wired signal, and the sending control cabinet information includes the name of the control cabinet that sends the hard-wired signal. The signal name refers to the name that the staff customizes for the convenience of monitoring the signal. For example, the diesel engine start signal refers to an instruction that can control whether the emergency diesel generator is working. The signal history change record contains the signal change record of the hard-wired signal within at least two recent hard-wired periodic test cycles.

[0052] Step S102 includes: for each hard-wired signal, determine whether the time interval from the last set position change of the hard-wired signal is greater than or equal to the first set time, if so, define the hard-wired signal as a signal to be tested. Among them, the first set time is less than the hard-wired periodic test cycle. It should be noted that the hard-wired periodic test cycle refers to the period for testing the reliability of the hard-wired signal (equivalent to the overhaul period). Due to the large number of hard-wired signals, if they are tested one by one, it will take a lot of time and may delay the construction period. The purpose of this step is to exclude the hard-wired signals whose time interval from the last set position change is less than the first set time, so as to reduce the number of hard-wired signals (i.e., signals to be tested) that need to be tested, thereby improving the test efficiency.

[0053] In some embodiments, whether a hard-wired signal has a setting change can be determined in the following manner: when the hard-wired signal is a switch signal, if the hard-wired signal has a level flip, it is determined that the hard-wired signal has a setting change; when the hard-wired signal is an analog signal, if the amplitude change rate of the hard-wired signal exceeds a setting change range, it is determined that the hard-wired signal has a setting change. The setting change range can be set, and can usually be set to ±1%.

[0054] Step S103 includes: generating a test point list according to all signals to be tested.

[0055] The importance and material of different hard-wired signals may be different. For example, some hard-wired signals are of high importance, so it is not recommended to eliminate them even if the time interval from the last set displacement is less than the first set time. Some high-intensity and relatively low-importance hard-wired signals have a low failure rate and their reliability can be tested again during overhaul. Therefore, in some embodiments, the nuclear power plant cabinet hard-wired signal test method may also include the following steps: determining whether a point table editing instruction is obtained; when a point table editing instruction is obtained, modifying the test point list according to the point table editing instruction.

[0056] In this embodiment, the staff can input the point list editing instruction by operating the human-computer interaction unit (such as a touch screen), and then edit and modify the test point list to improve the editing flexibility of the test point list.

[0057] In some embodiments, the nuclear power plant cabinet hard-wired signal test method may further include: determining whether a point table export instruction is obtained; when a point table export instruction is obtained, exporting a test point list. Accordingly, the test point list may also be determined in the following manner: setting the test point list by importing. It can be understood that this embodiment helps to simplify the editing steps when testing hard-wired signals each time. For example, the staff can edit the hard-wired signals with high importance (i.e., the hard-wired signals that must be tested) into the test point list in advance, thereby saving editing steps. Further, in order to further simplify the steps, after importing the pre-edited test point list, steps S101 to S103 may also be performed to obtain the automatically generated test point list, and then the pre-edited test point list and the automatically generated test point list are merged, and the merged test point list is determined as the final test point list, and subsequent steps are performed. Among them, the fusion step is specifically: using the hard-wired signals (or signals to be tested) contained in the two lists to form a new test point list (i.e., the merged test point list), and each hard-wired signal in the merged test point list does not appear repeatedly.

[0058] Step S20 includes: performing a validity test on each signal to be tested, including: controlling the control cabinet that receives the signal to be tested to lock the received signal to the current value; outputting a test signal that changes based on a set rule on the control cabinet side that outputs the signal to be tested; monitoring the test signal on the control cabinet side that receives the signal to be tested to determine whether the change of the monitored test signal complies with the set rule, and if so, determining that the hard-wired channel that transmits the signal to be tested is valid, otherwise determining that the hard-wired channel that transmits the signal to be tested is invalid.

[0059] In some embodiments, the step of outputting a test signal based on a set rule change can be performed by executing the following steps: when the signal to be tested is a switch signal, a test signal with a set value flip is output on the control cabinet side that outputs the signal to be tested; when the signal to be tested is an analog signal, a test signal with an amplitude change rate greater than the upper limit of the set change range or less than the lower limit of the set change range is output on the control cabinet side that outputs the signal to be tested. Correspondingly, the step of judging whether the change of the monitored test signal conforms to the set rule may include: when the signal to be tested is a switch signal, judging whether the set value of the monitored test signal has the same set value flip as the test signal output by the control cabinet side that outputs the signal to be tested, if so, judging that the change of the test signal conforms to the set rule, otherwise judging that the change of the test signal does not conform to the set rule; when the signal to be tested is an analog signal, calculating the error value between the amplitude of the monitored test signal and the amplitude of the test signal output by the control cabinet side that outputs the signal to be tested, judging whether the error value is within the set error range, if so, judging that the change of the test signal conforms to the set rule, otherwise judging that the change of the test signal does not conform to the set rule. Wherein, the set error range may be ±0.2%.

[0060] In order to avoid the hard-wired channel being in a locked state for a long time due to testing, thereby affecting the normal operation of the nuclear power plant, in some embodiments, after determining that the hard-wired channel transmitting the signal to be tested is valid, a channel recovery process is also performed. The channel recovery process may include: stopping the output of the test signal on the control cabinet side that outputs the signal to be tested, and after a delay of a second set time, controlling the control cabinet that receives the signal to be tested to stop locking the signal to be tested.

[0061] In some embodiments, the process of conducting the effectiveness test may also include the following steps: monitoring the real hard-wired signal output by the control cabinet that outputs the signal to be tested, and outputting an abnormal prompt signal when the real hard-wired signal has a set position change. Accordingly, the nuclear power plant cabinet hard-wired signal test method may also include the following steps: judging whether the test interruption instruction is obtained; when the test interruption instruction is obtained, stopping the effectiveness test and performing channel recovery processing. Since some emergencies may occur during the test, such as the real signal abnormality of a certain signal to be tested, some equipment abnormalities, etc., which lead to the need to terminate the test, and this embodiment can learn the actual changes of the real hard-wired signal by real-time monitoring of the real hard-wired signal output by the control cabinet that outputs the signal to be tested, and output an abnormal prompt signal when the real hard-wired signal has a set position change, which has the effect of reminding the staff, so that the staff can decide whether to input the test interruption instruction through the human-computer interaction unit according to the actual situation. In addition, please refer to the above for the specific judgment method of whether the real hard-wired signal has a set position change, which will not be repeated here.

[0062] In some embodiments, the process of conducting the validity test may also include the following steps: outputting real-time observation data according to each signal to be tested that has not been completed and has completed the validity test; wherein the real-time observation data includes the signal name of each signal to be tested, the signal history change record, the test progress and the judgment result. Specifically, the real-time observation data can be input into the human-computer interaction unit, so that the staff can observe the progress of the test in real time through the human-computer interaction unit, including observing each signal to be tested that has not completed the validity test, each signal to be tested that has completed the validity test and the signal to be tested that is being tested, and the test results of each signal to be tested that has completed the validity test (whether its hard-wired channel is valid). Furthermore, different colors can be matched to each signal to be tested that has not completed the validity test, each signal to be tested that has completed the validity test and the signal to be tested that is being tested to improve intuitiveness.

[0063] Step S30 includes: outputting a test report according to the determination results of each signal to be tested, wherein the test report may include the number of valid hard-wired channels, the number of failed hard-wired channels, and the sender control cabinet information, the receiver control cabinet information and the signal function information of each failed hard-wired channel.

[0064] It can be understood that the present invention achieves the technical effect of automatically testing multiple hard-wired signals, and the test work can be carried out with the participation of at least one staff member, which significantly improves the test efficiency of hard-wired signals and plays a positive role in reducing the operation and maintenance costs of nuclear power plants.

[0065] The present invention also provides a computer storage medium storing a computer program, which, when executed by a processor, implements the steps of the nuclear power plant cabinet hard wiring signal test method provided by an embodiment of the present invention.

[0066] like Figure 3 As shown, the present invention also provides a nuclear power plant cabinet hard wiring signal test device, including a host computer 1 and a network communication module 2.

[0067] The host computer 1 includes: a processor and a memory storing a computer program. When the processor executes the computer program, the processor implements the steps of the nuclear power plant cabinet hard wiring signal test method provided by the embodiment of the present invention.

[0068] The network communication module 2 is communicatively connected with the processor in the host computer 1 and the processing modules of multiple control cabinets, so that the host computer 1 can establish a communication channel with each control cabinet in the form of network communication.

[0069] In some embodiments, as shown in 3, the nuclear power plant inter-cabinet hard-wired signal test device may further include a human-machine interaction unit. The human-machine interaction unit is connected to the processor in the host computer 1 to output operation instructions such as point table editing instructions and test interruption instructions according to the operation of the staff, and display the test progress and test report.

[0070] like Figure 4 As shown, each control cabinet includes a processor and a maintenance interface, and also includes a DO board and / or a DI board. Due to the long length of some hard-wired connections, the amplitude of the hard-wired signal is attenuated. In order to improve the accuracy of the processor in detecting the hard-wired signal, the sending control cabinet will enhance the voltage or current amplitude of the hard-wired signal input to the hard-wired signal through the DO board to improve the quality of the hard-wired signal. Similarly, the receiving control cabinet will identify the received hard-wired signal through the DI board and convert it into a voltage signal with stable amplitude for the processing module to identify. It is understandable that since some control cabinets are communicatively connected to multiple control cabinets, and the role of transmitting the hard-wired signal may be either the sender or the receiver, some control cabinets will be configured with both DO boards and DI boards. Figure 4It can be seen that the DO board in the sender's control cabinet and the DI board in the receiver's control cabinet are connected in series with the hard wiring A and participate in the signal transmission process. In order to improve the test depth, in some embodiments, the network communication module 2 can be connected to the processing module in the sender's control cabinet and the DI board and processing module in the receiver's control cabinet through a maintenance interface, so that the host computer can control the processing module of the sender's control cabinet to realize the output of the test signal, and can also control the processing module of the receiver's control cabinet to lock the corresponding hard-wired signal to the current value, and communicate with the DI board to monitor the changes of the test signal after it flows through the DO board, hard wiring and DI board of the sender's control cabinet, and then determine whether the change of the test signal conforms to the set rule.

[0071] It should be noted that the existing hard wiring calibration method usually only focuses on the electrical performance of the hard wiring (such as whether there is a broken wire, a loose connection, etc.), and lacks testing of the functions of the DI board and the DO board. The present embodiment can comprehensively test the reliability of the DI board and the DO board, which helps to improve the test effect.
