Description

Technical Field

[0001] The present invention relates to the technical field of aircraft electrical maintenance training, and in particular to a modular electrical training and inspection device for aircraft maintenance. Background Art

[0002] The electrical maintenance project in the Aircraft World Skills Competition is the core unit of the aviation maintenance skills competition. It focuses on the diagnosis, troubleshooting and maintenance capabilities of the aircraft electrical system, and places extremely high demands on the contestants' theoretical knowledge, practical operation standards and emergency response. Therefore, an efficient modular electrical training device plays an important role in the basic training before the competition, and can meet the contestants' scientific, standardized and efficient training needs before the competition.

[0003] Currently, the electrical maintenance training equipment for the Aircraft World Skills Competition consists of a single panel. Trainees can only perform circuit design and troubleshooting on the panel based on a database of questions drawn from the competition. Furthermore, the electrical panels are typically fixed to a test bench, and each test bench can only accommodate one trainee for training and electrical system testing and scoring. Scoring still relies on simple logic judgments based on the use of traditional toggle switches and power indicators. The equipment is crude, inefficient, poorly accessible, and generally lacks performance.

[0004] In summary, the shortcomings of existing aircraft electrical maintenance training equipment are as follows:

[0005] 1. A single panel and bench-type structural layout is adopted. The panel and the bench are fixedly connected and cannot be quickly disassembled and assembled. Only one contestant is allowed to conduct electrical maintenance training on each bench, and the equipment reuse rate is low.

[0006] 2. The traditional toggle indicator light switch and power indicator light are used to inspect and judge the electrical system after repair. The inspection results cannot be automatically judged and scored, and the degree of automation of the equipment is low. Summary of the Invention
