Description

Technical Field

[0001] The present invention relates to the technical field of consulting and using logic control diagrams of nuclear power plants, and in particular to a method, system, equipment and storage medium for quickly locating fault points of a nuclear power system. Background Art

[0002] The logic control diagram (CLD) is a drawing of reactor protection and unit control during the operation of a nuclear power plant. It is the most important work document for the operation, maintenance, and technical departments of the front-line production department. Because nuclear power plants have many protection and control systems, each system corresponds to a logic control drawing. However, all current logic control drawings do not have the search and link jump functions of signal or alarm equipment. Each diagram only implements a certain function on the signal circuit of a certain instrument and equipment. It is not user-friendly to the front-line production department of the power plant, is relatively scattered, and is inconvenient to use and inefficient. When the unit encounters a transient, it triggers an alarm related to the machine and reactor tripping. If you need to understand the detailed logic involved upstream, you need to query the logic control diagram, find its location among hundreds or thousands of drawings in different systems, and then follow it to continuously flip through the multiple signals involved in different systems and different pages.

[0003] Therefore, a method for quickly locating fault points in nuclear power systems that efficiently utilizes logic control drawings, is searchable, and can automatically jump signals, is an urgent need for current nuclear power systems.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The embodiment of the present invention provides a method for quickly locating a fault point in a nuclear power system. Figure 1 , Figure 1 This is a flow chart of a first embodiment of a method for rapidly locating a fault point in a nuclear power system according to the present invention.

[0047] In this embodiment, the method for quickly locating a fault point in a nuclear power system includes steps S10 to S30:

[0048] Step S10, receiving alarm information, and locating the alarm device position in the logic control drawing based on the alarm information;

[0049] It should be noted that the alarm information may include the alarm device's identification, name, alarm category, trigger time, etc. Receiving means obtaining relevant alarm information through the digital control system (DCS) of the nuclear power system or other alarm collection devices.

[0050] Specifically, after receiving the alarm information obtained by the digital control system (DCS) or other alarm collection devices, you can quickly find the relevant page in multiple logic control diagrams (CLD) through the alarm information. Automatically jump to the drawing page where the alarm device is located, and highlight the location of the alarm device, intuitively showing the starting point of its logic flow.

[0051] In a feasible implementation manner, the step S10 of locating the alarm device position of the alarm device in the logic control drawing based on the alarm information includes:

[0052] The alarm device name of the alarm device is obtained based on the alarm information; the alarm device name is searched in the preset logic control retrieval software to locate the alarm device position of the alarm device in the logic control drawing.

[0053] Specifically, the name of the alarm device is obtained from the alarm information, and the alarm name is searched in the search box of the CLD search software, and the page where the alarm is located is automatically located and highlighted.

[0054] For example, refer to Figure 2 , search for the alarm device name 1711VP in the search box of the CLD retrieval software, automatically locate the 1711VP position, and highlight the 1711VP device name.

[0055] Step S20, obtaining the logic processing process of the alarm device at the alarm device location;

[0056] It should be noted that the logic processing process refers to the process in which a device is driven to work or triggers an alarm for the device by a certain module, device or signal point directly or indirectly receiving an input signal to it, such as an alarm device being triggered by a threshold module exceeding a threshold value, or an input switch signal triggering an alarm device alarm, etc. At the same time, the device can also input signals to other devices or modules. Each device, module or signal point has its own logic processing process. Obtaining the logic processing process means directly checking which modules or devices drive the device, or which signals input this signal point, through the logic flow of the page.

[0057] In addition, for a signal point, its logical processing process is which signals are input or output at this signal point.

[0058] Specifically, through the logic flow in the page, obtain the logical processing process triggered by the alarm device, and check which modules the alarm device is triggered by, such as the threshold module exceeding the threshold value trigger, or the input switch signal triggering, etc., causing the alarm device to alarm.

[0059] Step S30: locating the position of the alarm trigger source device in the logic control drawing based on the logic processing process.

[0060] Based on the logic processing process, find the location of the module that causes the alarm device to alarm (such as the threshold module, control module, etc.), and then based on the logic processing process, find the input signal of this module upward, locate the position of the input signal, and use this input signal to find the position of the upstream device in the logic control drawing. Search layer by layer until the position of the alarm trigger source device in the logic control diagram is found.

[0061] In this embodiment, the position of the alarm device on the logic control drawing is quickly found by receiving alarm information and locating the alarm device position in the logic control drawing based on the alarm information; the logical processing process of the alarm device is obtained at the alarm device position; based on the logical processing process, the alarm trigger source device is searched upward layer by layer to finally locate the alarm trigger source device position in the logic control drawing, thereby realizing rapid positioning of the fault point of the nuclear power system.

[0062] Based on the first embodiment of the present invention, in the second embodiment of the present invention, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. On this basis, after the step S30 of locating the alarm trigger source device position of the alarm trigger source device in the logic control drawing based on the logic processing process, the step S31 is also included:

[0063] Step S31, outputting the device information of the alarm triggering source device for equipment maintenance personnel to perform maintenance.

[0064] Specifically, after locating the position of the alarm trigger source device in the logic control diagram, the complete device information of the alarm trigger source device on the logic control diagram is enlarged, and the name of the alarm trigger source device is highlighted.

[0065] In this embodiment, by outputting the device information of the alarm trigger source device, the device maintenance personnel can intuitively and quickly determine the problem of the alarm trigger source device and perform maintenance.

[0066] In a feasible implementation manner, after the step S30 of locating the alarm trigger source device in the logic control drawing based on the logic processing process, the step S32 is further included:

[0067] Step S32, based on the logic processing of the alarm trigger source device, all downstream devices of the alarm trigger source device are acquired for maintenance by equipment maintenance personnel.

[0068] It should be noted that a downstream device refers to a device into which a signal output by a certain device flows directly or indirectly. For example, when the output signal of a certain control module enters a downstream threshold module as an input signal, the threshold module is its downstream device. For another example, the output signal of an alarm trigger source device passes through a signal distribution module and is then diverted to multiple logic processing units. These units can all be regarded as its downstream devices.

[0069] Specifically, check the logical processing process of the alarm trigger source device and find all downstream devices of the alarm trigger source device.

[0070] In this embodiment, by locating downstream equipment, the potential impact of the alarm trigger source equipment failure on the overall operation of the nuclear power unit can be fully evaluated, and maintenance references can be provided for equipment maintenance personnel to quickly restore the normal operation of the nuclear power unit.

[0071] Based on the first and second embodiments of the present invention, in the third embodiment of the present invention, the same or similar contents as those of the first and / or second embodiments can be referred to the above description, and will not be described in detail later. On this basis, step S30 locates the position of the alarm trigger source device in the logic control drawing based on the logic processing process, including steps A0 to A5:

[0072] Step A0, taking the alarm device as the target object; Step A1, judging whether the target object has an upstream signal point based on the logic processing process of the target object; if so, executing steps A2-A4; if not, executing step A5;

[0073] It should be noted that the upstream signal point is not a device or module, but a jump point. The upstream signal point is the signal output of a device or module, and it is also the signal input of a module or device. When the two modules or devices are far apart on the CLD drawing or on different pages, they can be jumped through this upstream signal point. The following describes the input and output of signals between the signal point and the device mentioned in this embodiment, with reference to Figure 6 and Figure 7 , the signal point names are not unique, such as Figure 7 There can be multiple signal points 0002, 0003, etc. on a page. The difference between signal points lies in the jump page (that is, jump mark), signal description and the device connected to the signal point. The signal point does not control the inflow and outflow of signals, but only describes the connection and jump of signals between devices or between devices and modules. For example, Figure 7In the example, the signal point 0003 connected to the "&" logic module can be jumped to the 3622B page by clicking its jump mark 3622B. The signal point 0003 is connected to the "&" logic module. The signal flowing through 0003 enters the "&" logic module, continues to flow into L21, flows into device 0021STP, drives device 0021STP to work, and device 0021STP generates a new signal to flow into Figure 6 Click the 0004 signal point, click the jump mark 5107B of the 0004 signal point, and you can see where this signal is input.

[0074] In addition, it should be noted that the upstream signal point is a relative concept. For a device that receives signal input, it can jump to the upstream device through the upstream signal point. For a device that outputs signals, this upstream signal point can be called a downstream signal point, and it can also jump to the downstream device through this downstream signal point.

[0075] Specifically, take the alarm device as the target object, obtain the logical processing process of the target object, check which modules or devices drive the target object, and then check which signal inputs these modules or devices have to drive the work. If these modules or devices have signal inputs to drive the work and then drive the target object to work, then it is determined that the target object still has upstream signal points. In addition, it is necessary to check whether the target object is faulty. If the target object has upstream signal points and the target object is not faulty, then steps A2-A4 need to be performed to find the location of the alarm trigger source device. If not, step A5 is performed to determine that the current location of the target object is the location of the alarm trigger source device.

[0076] Step A2, locating the upstream signal point position of the upstream signal point, and acquiring the logic processing process corresponding to the upstream signal point at the upstream signal point position;

[0077] Specifically, the user jumps to the upstream signal point position at the jump point of the upstream signal point, obtains the logic processing process of the upstream signal point at the upstream signal point position, and analyzes the logic processing process to determine the upstream device position of the upstream device of the target object.

[0078] In a feasible implementation manner, the step of locating the upstream signal point position of the upstream signal point includes steps A11 to A12:

[0079] Step A11, obtaining the jump identifier of the upstream signal point based on the logic processing process; Step A12, locating the upstream signal point position through the jump identifier.

[0080] It should be noted that there is a jump mark at the upstream signal point. By clicking on this signal mark, you can jump to the location of the upstream signal point on other pages of the CLD diagram. In addition, it should be noted that the CLD diagram is in PDF format. On the preset server, there are multiple databases storing the jump relationship, device information, etc. of devices, modules and signal points. Figure 5 , the principle of the automatic query jump CLD diagram of Hualong Nuclear Power is explained:

[0081] The preset server stores the CLD equipment information database, CLD diagram setting value database, Hualong CLD drawing file data format, CLD diagram jump relationship library and CLD diagram abbreviation library. These databases and data formats are integrated in PDF and ultimately constitute the Hualong Nuclear Power's automatic reference and jump CLD diagram.

[0082] Specifically, by analyzing the logical processing process of the target object, the jump mark of the upstream signal point is found, and the jump mark of the upstream signal point is clicked, and the upstream signal point position is automatically located through the CLD diagram jump relationship library.

[0083] Step A3, based on the logical processing process corresponding to the upstream signal point, determine the upstream device position of the upstream device of the target object; Step A4, obtain the logical processing process corresponding to the upstream device, and take the upstream device as the latest target object, and re-start from step A1; Step A5, determine the current position of the target object as the alarm trigger source device position.

[0084] Specifically, the logical processing process of the upstream signal point is obtained at the upstream signal point position, and the upstream device position of the upstream device of the target object is determined by analyzing the logical processing process. Then the logical processing process of the upstream device is obtained, and the upstream device is used as the latest target object. The execution is restarted from step A1 until the final alarm trigger source position is found.

[0085] In this embodiment, by analyzing the logical processing process of the target object, the problem of the device or module on the page where the alarm device is located is eliminated, and it is determined that the target object failure is caused by the upstream signal input, and the upstream signal point position of the input logical processing process is found on this page. The signal jump is performed through the support of the CLD jump relationship library and other databases in the server. Click the jump mark to jump to the upstream signal point of the page where the upstream device is located. By analyzing the logical processing process of this upstream signal point, the upstream device position is determined, and the logical processing process of the upstream device is obtained after the upstream device is checked and correct. Further analysis is performed on whether there is a corresponding upstream signal point in the upstream device, and the location of the alarm trigger source device is finally obtained through step-by-step analysis. With the support of the CLD jump relationship library and the analysis of the logical processing process, upstream signal points, etc., the system automatically jumps upward layer by layer, realizing the location of the fault point in the CLD drawing without manual search, which greatly saves the fault finding time.

[0086] It can be understood that in addition to the method of clicking to jump to the drawing, it is also possible to automatically jump to the CLD drawing where the alarm trigger source device is located according to the logical route. For example, after receiving the alarm information, the alarm device corresponding to the alarm information can be used as the starting point, and the logical processing process of the alarm device can be analyzed to determine whether there is a logical route of the fault signal upstream; after determining that it exists, the jump mark corresponding to the upstream signal point is found along the logical route where the fault signal exists, and the jump to the upstream signal point on the page where the upstream device is located is automatically jumped, and the upstream device is found along the logical route where the fault signal exists, and it is determined whether there is still a logical route of the fault signal upstream of the upstream device. If so, it will continue to jump automatically until the CLD drawing where the alarm trigger source device is found, if not, the upstream device is the alarm trigger source device.

[0087] In combination with the above-mentioned first embodiment and second embodiment, the present invention is described as follows:

[0088] For example, refer to Figure 3For example, the alarm information includes the alarm device name RCP6062KA. Search for the alarm point name in the search box of the CLD retrieval software or directly open the CLD diagram to search. After locating the CLD diagram page where RCP6062KA is located, view its logical processing process, which can be triggered by the 0278HC threshold module in the diagram, indicating that after the signal SH.68110010 of the upstream input of 0278HC meets the set value of "≥1" of the 0278HC threshold module, the signal will pass through the 0278HC threshold module and flow into RCP6062KA, triggering the alarm of RCP6062KA. Therefore, it is judged that there is an alarm trigger source device upstream of RCP6062KA. On the page where RCP6062KA is located, there is an upstream signal point 0010, and PZR PRESSURE DEVIATION is its description. The signal 0010 comes from page 6811, so click the jump mark (the red underline under 6811) to jump to Figure 4 The output signal 0010 SH.6006 (SH.6006 represents page 6006, 0010 SH.6006 represents signal point 0010 on page 6006, and 0010SH.6006 can also be regarded as the name of the signal on this page) is located at the upstream signal point 0010 on page 6006. Checking the logical processing process of the 0010 signal point on page 6006, it is found that the signal comes from the upstream device 6809RG. Through the analysis of 6809RG, it is found that the signal comes from the SpPos pin of the control module 6809RG, which is judged to be the alarm trigger source device.

[0089] It should be noted that for the upstream signal point 0010, there is page 6811 where the alarm device RCP6062KA is located, and there is also page 6006 where the upstream device 6809RG is located. The signal point 0010 on page 6006 outputs a signal to the alarm device RCP6062KA, and the upstream device 6809RG on page 6006 outputs a signal to the signal point 0010.

[0090] Based on the first, second and third embodiments of the present invention, in the fourth embodiment of the present invention, the same or similar contents as those of the first and / or second and / or third embodiments can be referred to the above description and will not be described in detail later. On this basis, the method for quickly locating a fault point in a nuclear power system also includes the steps of:

[0091] When a trigger signal is received from an external input device on a logic control diagram for any nuclear power equipment or signal point, the equipment information of the nuclear power equipment or the signal information of the signal point is output, wherein the nuclear power equipment includes alarm equipment, upstream equipment and downstream equipment, and the signal point includes an upstream signal point.

[0092] It should be noted that the external input device may be a mouse, etc., the trigger signal may be the operation of moving the mouse to the nuclear power equipment or signal point, the equipment information may be the equipment name, the position of the equipment on the CLD drawing, the equipment control conditions, the equipment structure, etc., and the signal information may be the page to which the signal point can jump, the signal description, etc. The nuclear power equipment includes every device, module, etc. on the logic control drawing, and the signal point includes every signal point, etc. on the logic control drawing.

[0093] Specifically, when receiving a trigger signal such as a move operation of an external input device such as a mouse on any nuclear power equipment or a signal point on a logic control drawing, the device information of the nuclear power equipment or the signal information of the signal point is output.

[0094] For example, refer to Figure 8 and Fig. 9 When the mouse moves into the signal point 0006, 0006 is highlighted. Based on the support of the CLD diagram abbreviation library, when you click the description of the 0006 signal LETDN with the mouse, a window will pop up to display the original word of this description as LETDOWN.
