The design method of a programmable wireless remote multi-channel switch system is introduced, and its composition and working principle are detailed. The system uses a single-chip microcomputer to perform software decoding on the received signal, which avoids the limitation of using a dedicated decoding chip, and can enhance the scalability and flexibility of the system, and has proved to be a feasible solution through experiments. 1 Introduction With the rapid development of integrated circuit technology, new remote control based on various types of chips has emerged. The central control unit of the remote control device has been gradually developed from the early discrete components and integrated circuits to the current single-chip microcomputer, and the degree of intelligence is greatly improved. In the field of wireless remote control, the currently used remote control methods mainly include ultrasonic remote control, infrared remote control, and radio remote control. Because the technical characteristics of radio waves can be realized in a large area and space, it becomes the main mode of remote control, and has wide application value in production, construction and daily life. To this end, based on the previous research, a design method of programmable radio remote control multi-channel switch system based on single-chip microcomputer control technology is explored. The research shows that the remote control switch system designed by this method is convenient to control and is suitable for occasions with more controlled appliances, which can realize multi-channel multi-function control. 2 system design 2.1 System Analysis The system structure mainly consists of an antenna receiving part, a signal transmitting part, a single chip control part and a driving part. Since radio signals are easily interfered by environmental factors, it is difficult to make a success without professional equipment. Wireless data transmission and cable are different. The transmitted data is stable only for a short period of time. If the time is long, it will be interfered. Therefore, the data must be transmitted when the data is transmitted. In the design, the high frequency part is selected for special use. The transmitting and receiving modules, while the data encoding and decoding are also completed by hardware, thus greatly improving the success rate of the production; the control part is the core of the system, in order to enhance the system's scalability and flexibility, and make the circuit simple and clear, Save hardware design costs and introduce mature microcontroller control technology into system control. The specific composition of the system is shown in Figure 1. Figure 1 System block diagram
