Modeling design method of digital screen cabinet for production test and matched test generation method

Abstract

The invention discloses a digital screen cabinet modeling design method for production test and a matched test generation method. According to the overall design, components, connector terminals, board cards, devices and logic loops in a simulated real environment in a software virtual environment establish a machine-recognizable digital model for a screen cabinet, a design modeling system establishes a digital model board card through a professional signal digital simulation set of tags, and then a digital device model is established; and finally, establishing a digital screen cabinet model; after modeling, generating a tested screen cabinet label signal set which can be recognized by a machine, and a topological network structure and a logic connection relation between the screen cabinet terminal model and the device terminal model. Therefore, a screen cabinet debugging outline is generated and used for carrying out production testing on the screen cabinet produced by a secondary manufacturer, and the tested screen cabinet which is actually produced after modeling is connected to a detection system through broadband network communication and a modern sensor technology to form a complete closed-loop manual semi-automatic detection system or an intelligent automatic detection system.

Problems solved by technology

[0005] The lack of automation and digitalization of quality management information in the production and testing process of secondary manufacturers is the fundamental difficulty in accessing the electrical platform, mainly reflected in the lack of generalization and standardized automatic testing of relay protection and intelligent device equipment (hereinafter referred to as IED). The common feature of "small batches and multiple varieties" is common in the manufacturing process

Even if the physical location is the same, the DUT itself is composed of several boards. Many manufacturers form different types of devices by designing a universal backplane compatible with different types of boards. As a result, boards with the same appearance but completely different functions are inserted in the same physical location. , the electrical signal of the detection point varies with different boards, which increases the difficulty of detection
