一、 Product Overview
According to the "Pilot Work Plan for Teaching Reform of Engineering Learning Integration Courses in Technical Colleges" designed by the Ministry of Human Resources and Social Security of the People's Republic of China, course objectives are determined around typical work tasks (i.e. sensor training modules), course content is selected, professional teaching plans are formulated, and relevant content in national vocational standards is followed. By combining the training of "sensor technology", "detection technology", and "industrial control technology" in the integration of electromechanical engineering with work tasks, typical work tasks can be quantified into multiple sub tasks, and the new concept of task led, project driven, and modular teaching can be gradually implemented, following the teaching laws.
Sensor technology is an important link in achieving testing and automatic control. In the testing system, it is used as a primary instrument positioning, and its main feature is the ability to accurately transmit and detect information in one form, and convert it into information in another form. Students can combine corresponding training circuits according to the requirements of the training project to complete practical tasks such as sensor selection, sensor principle, sensor circuit, sensor disassembly and assembly, sensor application, etc. It is suitable for vocational colleges, technical schools, and other training exams for basic electrical skills.
