Since 2020, with the gradual maturation of the Internet of Things and 5G technology, the smart home industry has ushered in a period of comprehensive explosion. The state has introduced multiple policies to encourage and support the development of the smart home industry. This course focuses on simple smart home systems and is based on the assessment content of the competition item for secondary vocational students in vocational college skills competitions, Electronic Product Assembly and Application. After a comprehensive analysis of the learning situation of secondary vocational students, six projects are designed: the DC regulated power supply module, the simulated exhaust fan module, the combustible gas detection module, the sound and light alarm module, the human body infrared detection module, and the microcontroller main control module. Each project can produce an independent electronic product. The DC regulated power supply module provides energy for all modules, and the microcontroller main control module can control the operation of the sound and light alarm module and the simulated exhaust fan module based on signals from the combustible gas detection module and the human body infrared detection module, thereby realizing two typical applications of smart home: kitchen safety and intelligent anti-theft.
Each project is implemented following the task flow of circuit design, component selection, simulation verification, drawing and board manufacturing, and soldering and debugging, accurately replicating the entire process of electronic product production and aligning the learning process with the production process.
The course emphasizes helping students clarify the steps of product production and safety operation standards, fostering quality awareness and safety consciousness among students; during the soldering and debugging tasks, the course adopts a six-step teaching method of inquiry, planning, decision-making, implementation, inspection, and evaluation, aiding students in developing good work habits.
