[0029] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] It should be understood that the specific embodiments described herein are merely used to explain the present application and are not intended to limit the present application. In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms are not necessarily directed to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they contradict each other.

[0031] A nuclear power plant's reactor control rod control system may experience abnormalities due to a Motion Drive Power (MDP) card failure. To address this, a dedicated MDP card measurement tool can be used to measure the voltage of each MDP card. This voltage can then be used to determine if a fault has occurred.

[0032] However, the method for collecting voltage of the MDP card in the prior art has low accuracy and cannot accurately obtain the voltage value of the MDP card.

[0033] Furthermore, the MDP card-specific measurement tool can only collect voltage for one MDP card at a time. Therefore, when determining whether each MDP card has a fault, the MDP card-specific measurement tool needs to be used to collect voltage for each MDP card one by one, which is a very time-consuming process.

[0034] Based on the above situation, this application discloses a system power supply card abnormality diagnosis device for a nuclear power rod control system, such as Figure 1 As shown, the diagnostic equipment includes a voltage acquisition device;

[0035] Voltage acquisition equipment is used to collect real-time voltage values ​​of at least two system power supply MDP cards in the nuclear power rod control system.

[0036] Each real-time voltage value is used to indicate whether the corresponding MDP card is abnormal.

[0037] It should be noted that the nuclear power plant's reactor control rod control system controls a total of 61 control rods. Each control rod is controlled by three coils: the stationary gripper (SG), movable gripper (MG), and lift coil (LC), each controlling three grippers to facilitate insertion and removal. The current for the 183 coils corresponding to the 61 control rods is generated by 16 power supply cabinets. Each cabinet houses SG / MG / LC racks, which control the current for the SG / MG / LC coils. Within each SG / MG / LC rack, power supply cards convert the upstream 260V AC power to the required DC power for the local coils. If a power supply card fails, the cabinet containing that card enters a double-clamping state. This means that all power supply cards in the SG and MG racks output half current, and the SG and MG grippers simultaneously secure the control rods to prevent them from falling.

[0038] The above-mentioned system power supply card abnormality diagnostic equipment in the nuclear power rod control system collects the real-time voltage values ​​of at least two system power supply MDP cards in the nuclear power rod control system through the voltage acquisition equipment. According to the above content, the diagnostic equipment of the present application can realize the acquisition and processing of the voltage of the MDP card through the voltage acquisition equipment, thereby achieving the purpose of accurately obtaining the voltage value of the MDP card. Moreover, the diagnostic equipment of the present application can also realize the simultaneous acquisition of the real-time voltage values ​​of at least two system power supply MDP cards through the voltage acquisition equipment, thereby preventing the staff from needing to use measuring tools to collect the voltage of each MDP card one by one, thereby improving the efficiency of voltage acquisition for multiple MDP cards.

[0039] In one embodiment, the voltage acquisition device includes an acquisition body and at least two sets of acquisition lines; each MDP card is connected to the acquisition body via a corresponding acquisition line;

[0040] The acquisition body is used to obtain the voltage signals of the corresponding MDP cards collected in real time by each acquisition line, and digitally convert each voltage signal to obtain the real-time voltage value of the corresponding MDP card.

[0041] It should be noted that the collection line includes a positive collection line and a negative collection line; the positive collection line is used to connect the first positive pole of the collection body and the positive end of the MDP card respectively; the negative collection line is used to connect the first negative pole of the collection body and the negative end of the MDP card respectively.

[0042] In one embodiment of the present application, the acquisition body includes at least two first positive electrodes and at least two first negative electrodes, wherein the number of the first positive electrodes is the same as the number of the second negative electrodes. When the acquisition body needs to obtain the voltage signal of the corresponding MDP card collected in real time by each acquisition line, the positive end of each MDP card can be connected to a different first positive electrode through the positive electrode acquisition line; and the negative end of each MDP card can be connected to a different first negative electrode through the negative electrode acquisition line.

[0043] The aforementioned nuclear power rod control system's system power supply card abnormality diagnostic device utilizes at least two sets of acquisition cables: a positive acquisition cable connecting the first positive terminal of the acquisition body to the positive terminal of the MDP card, and a negative acquisition cable connecting the first negative terminal of the acquisition body to the negative terminal of the MDP card. This ensures that the acquisition body can successfully acquire the voltage signal of the corresponding MDP card, thereby obtaining the real-time voltage value of the corresponding MDP card.

[0044] In one embodiment, the display screen in the voltage acquisition device enables the user to more intuitively determine the real-time voltage value of each MDP card through the system power supply card abnormality diagnosis device of the nuclear power rod control system. Specifically, the voltage acquisition device further includes a display screen connected to the acquisition body;

[0045] The display screen is used to display the real-time voltage value corresponding to each MDP card.

[0046] There are many types of display screens. For example, the voltage acquisition device may include a liquid crystal display, an organic light emitting diode display, an LED display, etc. The type of display screen is not limited here.

[0047] It should be noted that the voltage acquisition device also includes a display controller; the display controller is connected to the display screen;

[0048] A display controller, configured to generate a display control signal in response to a display control operation and transmit the display control signal to a display screen;

[0049] The display screen is also used to continuously display the real-time voltage value of each MDP card at the corresponding generation moment of the display control signal.

[0050] Among them, the display controller can be a button controller, a knob controller, a touch controller, etc. The controller type of the display controller is not limited here. Furthermore, on the premise that the display screen is a touch display, the display controller can also be integrated into the display screen to trigger the operation of the display controller through the touch display screen.

[0051] In one embodiment of the present application, if the display currently displays the real-time voltage values ​​of three MDP cards, when the user generates a display control signal through the display controller, the display controller will transmit the display control signal to the display screen. After receiving the display control signal, the display screen will continue to display the real-time voltage value of each MDP card at the corresponding generation moment of the display control signal.

[0052] To further illustrate, the number of display controllers corresponds one-to-one with the number of MDP cards;

[0053] Each display controller is respectively responsive to a display control operation and is used to generate a display control signal for a corresponding MDP card;

[0054] The display screen is used to continuously display the real-time voltage value of the target MDP card; wherein the target MDP card is the MDP card corresponding to the display controller that receives the display control operation.

[0055] In one embodiment of the present application, if the real-time voltage values ​​of four MDP cards are displayed on the display at the current moment, the four MDP cards are respectively a first MDP card, a second MDP card, a third MDP card, and a fourth MDP card, and a total of four display controllers are included, the four display controllers are respectively a first display controller, a second display controller, a third display controller, and a fourth display controller, wherein the first MDP card corresponds to the first display controller, the second MDP card corresponds to the second display controller, the third MDP card corresponds to the third display controller, and the fourth MDP card corresponds to the fourth display controller, when the user triggers the second display controller, the display controller generates a display control signal and transmits the display control signal to the display screen, and after receiving the display control signal, the display continuously displays the real-time voltage value of the second MDP card at the moment when the display control signal is generated.

[0056] The system power supply card abnormality diagnostic equipment of the above-mentioned nuclear power rod control system, by setting a display controller, allows users to understand the real-time voltage value of the MDP card more intuitively, thereby improving the user's operating experience. Moreover, when the number of display controllers corresponds to the number of MDP cards one-to-one, it can ensure that users can obtain the real-time voltage value of each MDP card in a targeted manner.

[0061] In one embodiment of the present application, the driving power supply can also power multiple devices.

In addition, by setting the driving power supply, there is no need to connect an external power supply when using the diagnostic equipment, which further improves the convenience of the diagnostic equipment and enriches the application scenarios of the diagnostic equipment.
