In view of the intelligent processing function of MCU chip, the design adopts the method of combining theory with experiment verification, and takes the main circuit of STC89C52 chip as the core. The units of each unit are designed and selected for the appropriate components. When selecting components, pay attention to the cost performance of the selected chip. In the design of the whole circuit, it is necessary to debug and simulate the corresponding functions of each unit circuit. The research content of this design is to design a multifunctional vision protector based on single chip microcomputer, which is composed of four functions of ranging, sensitivity, timing and temperature measurement, which can realize real-time clock display.
