Description

Technical Field

[0001] This invention discloses an automatic generation system and method for terminal wiring diagrams between electrical cabinets, belonging to the field of electrical technology. Background Technology

[0002] A terminal wiring diagram is a wiring diagram of terminals arranged according to their intended purpose. The diagram can, as needed, indicate the pin numbers of the complete sets of equipment or devices within the cabinet and the terminal numbers or equipment pin numbers between cabinets. It shows the wiring from the pin numbers of the complete sets of equipment or devices within each electrical cabinet to the terminals, as well as the external terminal wiring between electrical cabinets. This diagram is used to guide wiring on-site, wire checking, and subsequent operation and maintenance. Specifically, it shows the wiring from the pin numbers of the complete sets of equipment or devices within each electrical cabinet to the terminals. Figure 1 This is typically done by the electrical cabinet manufacturer, demonstrating the external terminal wiring between electrical cabinets. Figure 1 Terminal wiring diagrams are typically drawn by engineering design firms, and in current technology, these diagrams are drawn manually. This method suffers from low drawing efficiency and the potential for errors in the terminal wiring diagrams.

[0003] Due to the nature of the project, electrical cabinets for different systems or equipment are typically provided by different manufacturers, and their external cable connections, terminal definitions, and functions vary. To facilitate wiring, cable checking, and subsequent maintenance on construction site, it is necessary to draw terminal wiring diagrams for each electrical cabinet, clearly indicating the connection information of each cable between cabinets, including the name, code, terminal number, and cable number and model of the connected electrical cabinet. To ensure consistency of terminal wiring diagram information on both sides of any circuit cable connection, it is necessary to check the terminal wiring diagrams of both electrical cabinets one by one. This is usually done manually, which is inefficient and time-consuming. Taking a large hydroelectric power plant with three generating units as an example, there are approximately 4,000 cables connecting the various electrical cabinets. The workload of checking them one by one is enormous, and errors are easily made. These errors are difficult to detect during the design phase, resulting in erroneous design drawings being delivered to the construction site, potentially wasting related cables and slowing down the installation and commissioning progress.

[0025] like Figure 1 As shown, a first aspect of the present invention provides an automatic generation system for terminal wiring diagrams between electrical cabinets. The system includes an automatic wiring diagram generation module 104 and a cable information database 102 and an electrical cabinet information database 103 connected to the automatic wiring diagram generation module 104.

The cable connection information includes the name, code (or KKS) of the electrical cabinet on both sides of the cable, the terminal number and the cable number and cable model.

[0027] The electrical cabinet information database 103 is used to automatically identify the terminal wiring diagrams in each electrical cabinet in the electrical system provided by the manufacturer and store them centrally so that the software corresponding to the wiring diagram automatic generation module 104 can read the data.

[0028] The automatic wiring diagram generation module 104 is used to automatically draw the terminal wiring diagram between electrical cabinets based on the retrieved cable connection information and the terminal wiring diagram in the electrical cabinet.
