Description

Technical Field

[0001] The present invention relates to the field of nuclear power technology, and more specifically to a method, device, equipment and storage medium for drawing construction drawings of nuclear power cables. Background Art

[0002] There are a large number of on-site equipment in nuclear power plants. In order to realize large-scale control, measurement and protection functions, it is necessary to use cables to connect the on-site controlled equipment (instruments, valves, motors, switch panels, control cabinets, etc.) to the corresponding control cabinets one by one. Only in this way can the nuclear power plant operate well according to the prescribed control strategy, and the operator can centrally monitor and control the nuclear power plant in the main control room.

[0003] At present, the documents guiding the on-site cable connection construction during the construction of nuclear power plants are in the form of cable termination diagrams and cable termination tables. The cable termination diagram fully reflects the connection information and termination information of all equipment and cables (including penetrations, transfer boxes, switch panels, etc.) on the entire path from the on-site equipment to the final control cabinet. The drawings are intuitive and can conveniently and effectively guide installation, commissioning and maintenance. It is also the most commonly used form of cable construction drawings in nuclear power plants.

[0004] The design of nuclear power cable termination diagrams mainly uses CAD software and related plug-ins. The relevant equipment modules and cables need to be manually dragged into the drawings by designers. A large amount of information needs to be manually input or selected one by one, which is very error-prone. In addition, there is no overall database for each device and termination. The automatic correlation and output of signals cannot be achieved during the design process, which affects the efficiency and accuracy of cable termination design.

[0005] A Chinese patent with publication number CN103853859B discloses a method and system for drawing a nuclear power plant termination diagram, which mainly includes: S1, importing preset termination data into the drawing system; S2, after selecting cables and equipment in the drawing system, establishing a logical connection relationship between the equipment through cable connection; S3, after configuring a preset number of terminals for the equipment, automatically allocating the terminals of the control cabinet according to the preset termination data and establishing a connection logical relationship between the terminals of the cables and equipment and the terminals of the control cabinet; S4, completing the drawing of the minimum unit diagram of the nuclear power termination diagram; S5, automatically assigning the minimum unit diagram and completing the drawing of the nuclear power termination diagram.

[0006] The technical defects of this patent solution are: (1) it can only import the termination data of the DCS supplier. There is no relevant database for other large amounts of equipment information and equipment termination information. They can only be filled in manually one by one, which is inefficient and prone to errors. (2) The equipment information of each layer of cable connection needs to be filled in manually, which cannot fully guarantee the consistency with the transmission signal, cannot realize automatic equipment identification and matching connection, and cannot guarantee the integrity of the system design.

[0007] A Chinese patent with publication number CN104571016A discloses a method and system for visual operation and maintenance of a nuclear power plant DCS, which mainly includes: establishing a nuclear power plant DCS basic database, the basic database including a primary instrument sub-database, an actuator sub-database and an operation and maintenance knowledge base; obtaining transmission path information and cable termination information of a nuclear power plant DCS signal through a visual DCS operation and maintenance interface; searching for operation and maintenance related files according to the transmission path information and cable termination information; and performing operation and maintenance operations according to the operation and maintenance related files and the basic database.

[0008] The technical defect of this patent solution is that the establishment of the database is based on the results after the final cable termination is completed, and it cannot be used for the cable termination design during the construction phase of the nuclear power plant, and cannot improve the convenience of the termination design.

[0009] The Chinese patent with publication number CN115544696 A discloses a system and method for automatically generating a termination diagram for control and measurement cables in a nuclear power plant, which mainly includes: a terminal block signal matching module, a terminal block signal analysis module, a cable core number and section selection module, and a cable verification module. The system uses the electrical typical termination table and the instrumentation / distributed control cabinet termination table as input, and is based on the engineering cable database. Through the correlation matching and classification of the terminal block signal, the system determines the number of cables and the number of cable cores, and automatically outputs the cable termination diagram, the cable system diagram, and the cable inventory.

[0010] The technical defect of this patent solution is that the object of the termination design is to connect the termination information table on the electrical panel cabinet side and the termination information table on the distributed control cabinet cabinet side, and it is only for the control and measurement cables between the electrical panel cabinet and the distributed control cabinet cabinet. Due to their respective particularities, the cables between a large number of other field equipment (instruments, valves, motors, control cabinets, etc.) in nuclear power plants and distributed control cabinet cabinets cannot be directly designed using this solution. For the cable termination diagram design of the entire nuclear power plant, this solution is not universal and cannot achieve automatic connection and diagram output.

[0011] As can be seen from the above, when designing the termination diagram of nuclear power cables, there is no relevant database for a large amount of equipment information and equipment termination information, which can only be manually input one by one, which is inefficient and prone to errors, and the accuracy of the information cannot be guaranteed; the equipment information of each layer of cable connection needs to be filled in manually, which cannot realize the automatic connection design of signals, cannot fully guarantee the consistency with the transmission signal, and cannot guarantee the integrity of the entire termination design. Therefore, the current design method and efficiency of nuclear power cable construction drawings need to be further improved. Summary of the invention

[0012] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method, device, equipment and storage medium for drawing nuclear power cable construction drawings, aiming to achieve fully automatic generation of cable system diagrams and cable termination diagrams to ensure the quality and efficiency of the design.

[0058] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0059] At present, when designing nuclear power cable termination diagrams, a large amount of equipment information and equipment termination information has no relevant database and can only be entered manually one by one, which is inefficient and prone to errors, and the accuracy of the information cannot be guaranteed. The equipment information of each layer of cable connection needs to be filled in manually, and the automatic connection design of the signal cannot be realized, the consistency with the transmission signal cannot be fully guaranteed, and the integrity of the entire termination design cannot be guaranteed.

[0060] In order to solve the above problems, the present invention is proposed, and the present invention is mainly used in the cable system design of nuclear power plants. In nuclear power plants, there are a large number of field devices, such as various instruments (sensors such as temperature, pressure, flow, etc.), valves, control cabinets, etc. These devices need to be connected by cables to achieve signal transmission and equipment control. Therefore, the design of the cable system diagram requires accuracy, efficiency and can ensure the integrity and reliability of the system. The equipment system of a nuclear power plant is highly complex, the connection relationship between the equipment is numerous, and the signal types are diverse (including analog signals and digital signals, different voltage and current ranges, etc.). Moreover, the safety and accuracy requirements of the equipment are extremely high, and any errors in cable connection or termination may lead to serious consequences. Therefore, a systematic and highly automated cable system diagram design scheme is needed to meet these requirements. The present invention is introduced below through specific embodiments.

[0061] like Figure 1 As shown, an embodiment of the present invention provides a method for drawing a nuclear power cable construction drawing, comprising the following steps: S10-S60.

[0062] S10. Create a database of various types of equipment and a database of various types of equipment terminations on all cable paths in the nuclear power plant.

[0063] In nuclear power cable systems, there are many different cable paths, each of which involves various types of equipment, such as instruments, valves, panels, cabinets, penetrations, etc. Creating a database of various types of equipment is to comprehensively cover all equipment information on these different paths.

[0064] The cable termination diagram fully reflects the termination information of all equipment (including penetrations, transfer boxes, switch panels, etc.) and cables on the entire path from field equipment (instruments, valves) to the final control cabinet. In order to automatically realize the automatic identification and connection of equipment related to cable transmission signals, it is necessary to create a database of various types of equipment and a database of various types of equipment terminations to facilitate the automatic identification and association of signals and equipment.

[0065] The created equipment database includes the database of instruments, valves, panels, cabinets, penetrations, switch panels, control cabinets, DCS terminations and cables; each database includes the equipment code, equipment location, equipment part number and the mapping relationship between the equipment and I / O signals. The penetration equipment also includes the different room numbers inside and outside the containment, the core rod number information of the penetration, and the switch panel also includes the loop number information of the equipment. These equipment databases provide the data basis for the automated design of the cable system diagram. Of course, you can delete, modify and other operations on various types of equipment information in the equipment database.

[0066] The equipment arranged in the cable path can have several types of standard termination information according to the equipment model and wiring method. For each type of equipment, define its different termination information and define a unique termination number (such as MT-01). Organize and define the termination information of each type of equipment one by one, so as to build a termination database for all equipment. Each termination data number corresponds to a unique cable termination form.

[0067] The termination information includes the equipment code, part number, terminal number, corresponding cable core number and terminal short-circuit relationship, etc. The termination information can be used to fully express the equipment termination information in the cable termination diagram.

[0068] It should be noted that the equipment database and the equipment termination database are two interrelated parts with different contents, and they play different roles in the technical scheme of nuclear power cable construction drawings.

[0069] The device database is like the "ID card information library" of the device. Through this information, each device can be uniquely identified, and the location of the device in the entire system and how it corresponds to the input and output signals can be known.

[0070] The device termination database is used to fully express the device termination information in the cable termination diagram. In the process of cable system diagram design, this database will be used when configuring the typical terminations corresponding to each layer of equipment. Select the corresponding termination standard number from the device termination database to determine the specific termination information of each device and complete the cable termination configuration. This is like when connecting the lines of electrical equipment, the device termination database provides specific wiring guidelines for each device connector to ensure that the line is connected correctly.

[0071] For step S10, by creating various types of equipment databases and various types of equipment termination databases, a comprehensive data foundation is provided for the subsequent cable termination design of different equipment, which can be applied to more types of field equipment, rather than only for the cable termination design between specific electrical panels and distributed control cabinets as in the prior art, and the detailed information of the equipment can be directly obtained from the equipment database, without having to search for a large amount of equipment information, thus avoiding the situation where a large amount of equipment information has no database and can only be filled in manually. At the same time, no matter what kind of field equipment termination design, the corresponding standard termination information can be found in the equipment termination database, which solves the problem that the prior art cannot perform cable termination design for a large number of other field equipment in nuclear power plants, and greatly improves the universality of the scheme in the cable termination design of different equipment in the entire nuclear power plant.

[0072] S20, selecting a cable termination device in a certain cable path and matching the relevant information of the cable termination device according to the device database.

[0073] In one embodiment, step S20 specifically includes the following steps: S201 - S203 .

[0074] S201. Randomly select a cable starting device in a cable path.

[0075] Since there are many cable paths, each cable path has its starting device (i.e., the starting device), a cable starting device is randomly determined from these paths. Of course, the designer can perform a random selection operation through a specific selection algorithm or on a software interface.

[0076] S202: Automatically search for device I / O signal information corresponding to the cable starting device from a device database and automatically associate the information.

[0077] The equipment database stores detailed information on various types of equipment in the nuclear power system, including the I / O signal information of the equipment. When the cable start device is selected, the system will quickly search for the corresponding I / O signal information in the equipment database based on the unique identifier of the cable start (such as the equipment code). These I / O signal information include the output signals that the equipment can generate and the input signals that it can receive. The system automatically associates these I / O signal information with the cable start device to establish a close connection between the two.

[0078] S203, after the cable starting device is automatically associated with the corresponding device I / O signal information, the relevant information of the cable starting device is automatically matched through the device database, and the relevant information includes the device code, device part number and device location information.

[0079] Based on the established association, the system extracts more detailed information about the cable start device from the device database, such as the device code, device part number, and device location information. The device code is the unique identifier of the device in the entire system, which facilitates accurate identification of the device during the design and management process; the device part number helps to accurately select parts when maintaining or replacing the equipment; and the device location information is crucial for planning the cable laying path.

[0080] For steps S201-S203, through automated search and association operations, the workload of designers in manually searching and matching information is reduced, and the speed of obtaining relevant information of the cable termination equipment is greatly improved. At the same time, the information is automatically obtained from the equipment database and associated and matched, avoiding the errors that may be caused by manual operation, and ensuring the accuracy of the relevant information of the cable termination equipment. In addition, the cable termination equipment serves as the basis for subsequent signal transmission and equipment connection, thereby speeding up the design process of the entire cable system diagram.

[0081] S30, gradually matching all devices on the cable path along the data flow direction of the cable path where the cable starting device is located according to the relevant information of the cable starting device and the device database, and establishing connection relationships among all devices on the cable path using the selected cable.

[0082] The goal is to gradually configure all devices from a single cable start-end device to the final control cabinet, connect these devices through cables, build a complete cable signal transmission path, and ensure that the signal can be correctly transmitted between these devices.

[0083] In one embodiment, step S30 specifically includes the following steps: S301 - S303 .

[0084] S301. Filter out the next-level device that matches the cable starting device from the device database according to the relevant information of the cable starting device.

[0085] When the cable starting device is selected and its related information (such as device code, I / O signal information, device type, etc.) is obtained, it will automatically filter in the device database based on this information to obtain the matching next-level device.

[0086] S302, based on the next level device, select a new next level device that matches it from the device database, and so on, until all devices on the cable path where the cable starting device is located are selected.

[0087] After the first step of filtering out the next level device is completed, the device is used as a new basis and the above screening process is repeated. At this time, according to the output signal information of the new device, a device that can receive the output signal will be searched in the device database as the new next level device. Repeat the above screening process, and then match the subsequent devices in the order of signal transmission.

[0088] S303: Select a cable that meets the requirements from the device database according to the signal transmission requirements of all devices on the cable path, and use the selected cable to establish a connection relationship between all devices on the cable path.

[0089] After all the devices on the cable path are determined, it is necessary to select appropriate cables according to the signal transmission requirements of these devices. Since the cable database in the device database is configured with the material code for selecting cables, the specific selection information of the cables is clear. According to the signal transmission requirements between the devices, the most suitable cable can be selected from the cable database. After the cable is selected, the connection relationship of all the devices on the cable path is established using the cable. It should be noted that at this time, only the connection relationship of the devices is established through the cable. Since the termination information of the devices has not been clarified, the real connection has not been made.

[0090] For steps S301-S303, through accurate screening and matching based on device information, it can ensure that the device connection on the cable path meets the signal transmission logic and device compatibility requirements, reduce signal transmission problems caused by device connection errors, and thus improve the accuracy of the entire cable system design. At the same time, the automated device screening and cable selection process greatly reduces the workload of designers to manually find and match devices, saving a lot of time. At the same time, the orderly steps and systematic operations make the entire design process more efficient.

[0091] S40. Generate termination information of all devices on a certain cable path according to a device termination database to obtain a cable system diagram of the certain cable path.

[0092] In one embodiment, step S40 specifically includes the following steps: S401 - S402 .

[0093] S401. Search the device termination database for corresponding termination numbers of all devices on the cable path.

[0094] Step 30 has automatically matched all devices on the cable path, and the device termination database has pre-stored the termination numbers and detailed termination information corresponding to different termination methods of various types of devices. Therefore, accurate searches can be performed in the device termination database based on the information of each device.

[0095] Each device has its corresponding record in the database, including multiple possible termination methods and corresponding termination numbers. The search process can be based on factors such as the type and model of the device and its functional positioning in the cable system to determine the most appropriate termination method for the device under the current cable path and obtain its corresponding termination number.

[0096] S402. Connect all devices on the cable path to the cable according to their corresponding termination numbers.

[0097] After obtaining the termination numbers of all devices on the cable path, the detailed termination information corresponding to each termination number can be obtained naturally. This information includes the terminal number of the device, the corresponding cable core number, the terminal short-circuit relationship, etc. Based on this termination information, the connection process will be simulated in the cable system design software.

[0098] Of course, during the simulation process, the connection details between the cable and the equipment will be clearly marked on the cable system diagram, including the direction of the cable, the specific port location connected to the equipment, etc., so as to generate a complete cable system diagram.

[0099] For steps S401-S402, the accuracy of the equipment termination information on the cable path is ensured through accurate search and matching of the equipment termination database, avoiding termination errors caused by human misjudgment or incomplete information. This enables the generated cable system diagram to accurately reflect the actual equipment connection status, providing a reliable basis for subsequent construction and maintenance.

[0100] S50, repeating steps S20, S30 and S40 to obtain the cable system diagram of all cable paths.

[0101] By repeating steps S20, S30 and S40, all cable paths in the nuclear power plant can be covered, ensuring that the generated cable system diagram covers the entire nuclear power cable system.

[0102] According to the actual situation, the cable system diagram information inspection rules can be established. After the cable system diagram design is completed, a one-click inspection can be carried out, using the comparison inspection of the information in each database and the cable system diagram, and the compliance inspection of the information in the cable system diagram according to the drawing rules, to achieve detailed inspection and proofreading of the cable system diagram information, and further effectively ensure the design quality of the cable construction drawing. The inspection rule examples are as follows, which can be added and modified according to the project situation:

[0103] Check whether the selected I / O signals in the cable system diagram are complete and whether they are missing or not compared with the system's I / O list;

[0104] Check the consistency between the equipment assignment, part number, terminal information, room information, cable standard termination number, cable terminal block information, etc. in the cable system diagram and the equipment database;

[0105] In the cable assignment of the cable system diagram, check the consistency between the cable data, the attributes corresponding to the cable material code, and the material code;

[0106] The consistency of the termination information in the cable system diagram and the termination database;

[0107] Check whether the cables and devices are connected, and check if there are any cables connected to the devices;

[0108] Check whether the cable codes are repeated and list the problems if there are any;

[0109] Check whether the device code + part number combination code of a certain device is repeated

[0110] Check whether the cable core numbers are repeated and whether they are consistent with the cable material code.

[0111] S60. Generate a cable termination diagram for all devices based on the cable system diagram of all cable paths.

[0112] Based on the completed cable system diagram, cable termination diagrams can be automatically generated in batches according to the equipment connection and termination information, thereby ensuring the data consistency between the cable system diagram and the cable termination diagram, and simplifying the work of repeated drawing.

[0113] It should be noted that, since it is known that each device generates a detailed cable termination diagram, the cable system diagram of all cable paths can be obtained by summarizing, so that the cable termination diagram can be automatically generated in batches.

[0114] In one embodiment, step S60 further includes the following steps: S70 - S90 .

[0115] S70. When the termination information of a device changes according to demand, the changed termination information of the device is imported into a device termination database.

[0116] S80, detecting information differences in the device termination database before and after the import.

[0117] S90. Update the device termination database according to the difference information.

[0118] For steps S70-S90, a termination information update process and method are established. When the termination information of the changed device is imported into the device termination database, the information difference with the current device termination database will be automatically detected, and the difference will be pushed to the corresponding system manager. After confirmation by the system manager, the corresponding device termination information in the cable termination diagram can be directly updated with one click without affecting other design information. This effectively realizes the automated processing of termination information changes and ensures the integrity and accuracy of the change processing.

[0119] In summary, the present invention establishes a data streaming mapping method based on the device database and the device termination database, which automatically matches the device information of each device on the cable path and the termination information of each device, forming a complete automated process. There is no need to manually enter the device information and the device termination information one by one, which effectively reduces human errors and improves design quality and efficiency.
