Description

Technical Field

[0001] The present invention belongs to the technical field of nuclear power plant cable drawing, and particularly relates to an automated drawing method, system, device, and medium for nuclear power cable construction drawings. Background Art

[0002] There are a large number of on-site devices in a nuclear power plant. To achieve a large-scale control, measurement, and protection function, cables are required to connect each on-site controlled device (instruments, valves, motors, switchboards, control cabinets, etc.) to the corresponding control system one by one. Only in this way can the nuclear power plant operate well according to the specified control strategy, and at the same time, operators can centrally monitor and control the nuclear power plant in the main control room.

[0003] Currently, there are two forms of documents for guiding on-site cable connection construction during the construction of nuclear power plants: cable connection diagrams and cable connection tables. Among them, the cable connection diagram completely reflects the termination information of all devices and cables (including penetrations, transfer boxes, switchboards, etc.) on the entire path from on-site devices to the final control cabinet. The drawing is intuitive and can conveniently and effectively guide installation, commissioning, and maintenance. It is also the form that is used more frequently for cable construction drawings in current nuclear power plants. The cable connection table can only reflect the local device termination information at both ends of a single cable and cannot comprehensively understand the information of the entire signal channel, which is not convenient for installation, commissioning, and maintenance. It is usually only used in relatively simple systems in nuclear power plants and is used less overall.

[0004] The design of nuclear power cable connection diagrams mainly uses CAD software and related plug-ins. Relevant equipment modules and cables need to be manually dragged into the drawing by designers, and a large amount of information needs to be manually input or selected one by one, which is extremely error-prone. The overall drawing cannot achieve automated association and batch drawing, affecting the efficiency and accuracy of cable connection design.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0025] In the following description, a large number of details are explored to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0026] First of all, it should be noted that in order to enable the personnel in the technical field of this application to better understand the solution of this application, the technical background of this application is explained accordingly.

[0027] Currently, the existing cable drawing methods have the following defects: the drawing system can only import the termination data of DCS (Distributed Control System) suppliers, and a large amount of other device information and the termination information of devices can only be manually input. Moreover, the terminal information of devices also needs to manually input signal codes for retrieval, and automatic identification and matching connection cannot be achieved. At the same time, both devices and cables need to be manually input and then connected one by one, and automatic batch drawing cannot be achieved.

[0028] Or it is only designed for the control measurement cable termination between electrical panel boxes and cabinets of distributed control systems. However, due to their respective particularities, the cables between a large number of other on-site devices (instruments, valves, motors, control cabinets, etc.) in nuclear power plants and the cabinets of distributed control systems cannot be directly designed.

[0029] Therefore, in order to solve the above problems, this application proposes an automated drawing method for nuclear power cable construction drawings.

[0030] Embodiment 1 Please refer to Figure 1 An automated drawing method for nuclear power cable construction drawings as shown, including: Step S110, pre-create a first standard database for the connections between various devices in a nuclear power plant; wherein, the first standard database defines the logical relationship of each type of device connected to the terminal device and marks a unique first standard number.

[0031] Step S120: Pre-create second standard data regarding the terminations of each device in the nuclear power plant; wherein, the second standard database defines the termination information of each type of device and assigns a unique second standard number.

[0032] It can be understood that in this application, by pre-constructing the logical relationships of the cable connections of all devices in the nuclear power plant and storing them in the database, when a corresponding device is recognized, the logical relationships of the corresponding cable connections can be directly called from the database for automatic drawing, thereby generating a cable system diagram.

[0033] Specifically, it is necessary to separately create a first standard database regarding the connections between each device in the nuclear power plant and second standard data regarding the terminations of each device in the nuclear power plant. Among them, the first standard database defines the logical relationships of each type of device connected to the terminal device and assigns a unique first standard number. The specific meaning explains the way in which a certain type of in-situ device in the nuclear power plant is connected to the control system (control cabinet) through cables, and the control system mentioned here is the corresponding terminal device. Therefore, for each type of device, taking this type of device as the starting point and the corresponding terminal device as the ending point, define the logical relationships that this type of device needs to be connected to the terminal device through other different devices, that is, intermediate devices. For example, it can be seen in Figure 2 、 3 As shown, the ways in which different types of devices are connected to the corresponding terminal devices are correspondingly different. At the same time, a unique first standard number is defined for the logical relationships of the connections of this type of device for identification. The first standard number defined here can be customized according to the numbers of all devices, for example. Thus, it can be seen that the first standard database will pre-store the ways in which different devices are connected to the terminal device, so that a standard diagram of cable connection relationships can be constructed based on it, and each device and the cable connection relationship standard number correspond to a unique cable connection relationship standard diagram.

[0034] The second standard database defines the termination information for each type of device and assigns a unique second standard number. Specifically, it explains that for a certain type of in-situ device in a nuclear power plant, different termination information will exist according to different models and internal terminal wiring methods. For example, although it can be known from the first standard database that device A needs to be connected to device B via a cable, since there are multiple terminals in device A and device B, the connection methods between different terminals of device A and device B need to be obtained through the second standard database. Therefore, for each type of device, it is necessary to define the logical relationship of all terminal connections, that is, which type of other terminals a certain terminal should be connected to. At the same time, a unique second standard number is defined for the logical relationship of the terminal connections of this type of device for identification. The second standard number defined here can be customized according to, for example, the coding, part number, terminal number, and cable core number of this type of device. Thus, the connection methods of different device terminals are pre-stored in the second standard database, and a complete cable system diagram can be constructed based on its connection methods to all devices.

[0035] Step S200: Obtain the device input / output signal list of the system to be built.

[0036] Step S300: Query relevant devices in the device list database according to the input / output signals listed in the device input / output signal list, and obtain the first standard number and the second standard number of the relevant devices.

[0037] Step S400: Load the logical relationship of connections between all devices according to the first standard number, and load the termination information of the devices according to the second standard number to generate the cable system diagram of the system to be built.

[0038] After creating the first standard database and the second standard database, the device input / output signal list of the system to be built can be identified accordingly. It should be noted that the system to be built mentioned here is the device system required to be configured in a nuclear power plant, such as a monitoring system, a collection system, a safety management system, etc. Since different systems require different devices, corresponding device I / O signal lists will be configured, that is, what the input signals and output signals of the system are during operation, so as to finally feedback to the corresponding control system, as well as the signals that the control system needs to feedback.

[0039] In this regard, for each I / O signal listed in the device I / O signal list, the device type corresponding to the information can be queried in the device list database. For example, if the I / O signal of a certain type of device in the device list database is the same as a certain I / O signal in the I / O signal list, it is considered that this type of device can be used when constructing the system. And since each type of device has a unique first standard number and second standard number predefined, when the device type corresponding to the information is queried, the corresponding first standard number and second standard number can be obtained accordingly, so that the logical relationship of cable connection and termination information can be called from the first standard database and the second standard database based on the first standard number and the second standard number.

[0040] Furthermore, according to the device I / O signal list, different types of devices required for constructing the system, as well as the corresponding first standard number and second standard number, can be queried. Among them, first, the logical relationship of the connection of the corresponding device needs to be loaded from the first standard database for each first standard number, so that by integrating all the information, the different devices required for constructing the system and the cable connection relationship between different devices can be obtained as the framework of the system cable connection. Secondly, for each second standard number, the termination information of the corresponding device needs to be loaded from the second standard database to obtain the logical relationship of the connection of all the terminals of the device, so as to supplement the specific connection information to the above framework. Finally, according to the cable connection method between all devices and the cable connection method of each device to each terminal, the cable connection diagram of the system to be built is automatically generated to complete the corresponding drawing work.

[0041] Among them, it should also be supplemented that when generating the corresponding cable connection method for each terminal of a certain device, a cable of the corresponding model needs to be selected for connection. In this regard, the cable type selection can be carried out according to the relevant information of the device. Specifically, first, the type information of the cable can be determined according to the type of the device, such as control cable, measurement cable, low-voltage cable, etc. Secondly, it can also be further determined according to the input / output signal of the device and the input / output signal of the terminal, such as digital quantity, analog quantity, etc. In addition, the cable model can also be determined according to other factors such as the location of the device, the location of the terminal device, and the safety classification. There is no excessive limitation on this. Those skilled in the art, without departing from the spirit of the present invention, the modifications and retouches made to the embodiments of the present invention still fall within the scope of the invention application patent of the present invention.

[0042] Finally, after determining the cable model of each terminal, each cable can be numbered, and then each terminal of the device can be connected according to the number.

[0043] It should be noted that during the above process of automatically generating the cable system diagram, manual adjustment can also be carried out, and there are no excessive restrictions on this.

[0044] In a specific embodiment, the corresponding cable termination diagrams can be batch-generated according to the constructed cable system diagram, thereby ensuring the data consistency between the cable system diagram and the cable termination diagrams and simplifying the work of repeated drawing.

[0045] Thus, based on the automatic drawing method provided in this embodiment, the corresponding cable construction diagrams can be automatically and batch-generated, greatly improving the drawing efficiency and significantly reducing manual operations.

[0046] It should be noted that the step division of the above various methods is only for clear description. During implementation, they can be combined into one step or some steps can be split into multiple steps. As long as the same logical relationship is included, they are all within the protection scope of this application; adding insignificant modifications to the algorithm or process or introducing insignificant designs, but not changing the core design of the algorithm and process, are all within the protection scope of this application.

[0048] The second database module 20 is used to pre-create a second standard database for the terminations of various equipment in the nuclear power plant; wherein, the second standard database defines the termination information of each type of equipment and marks a unique second standard number.

[0049] The data calling module 30 is used to obtain the equipment input / output signal list of the system to be built.

[0050] The data processing module 40 queries relevant equipment in the equipment list database according to the input / output signals listed in the equipment input / output signal list and obtains the first standard number and the second standard number of the relevant equipment.
