JG-500 household appliances training device: rice cooker, electric fan, washing machine, dishwasher, disinfection cabinet, microwave oven bench

1 Overview

Household appliances laboratory equipment is an assessment device that integrates various household electrical appliances, including common failures of rice cookers, electric fans, washing machines, dishwashers, disinfection cabinets, and microwave ovens. Daily household appliances can be realized through household appliances laboratory equipment Maintenance, the entire training room is composed of training platform components, training tables, training units and supporting training objects, to achieve the assessment network, the teacher computer and the training platform form an assessment network, and faults can be set on the teacher computer , Students use the clicker to answer questions, and systematically monitor and manage the experimental data and experimental processes generated by the students during the experiment. Appliance maintenance training equipment enables students to submit experimental data, teachers monitor the experimental process, and correct experimental reports through the LAN And performance statistics and assessment are fully automated. The experimental process is fast and accurate, the experimental data is real, and the centralized management is suitable for the needs of modern education, which realizes the open teaching of the laboratory.
