Abstract
This paper intruduce radio-controlled system. The reason say it simple because the whole system Simplified the design of control targets, the object of control was just a few of the LED, used it only to prove that my designed radio remote control system whether reasonable or not, whether operation or not. nearly a month after the assembly, welding, testing to proved that the whole design is to achieve long-distance wireless control. This paper is around the related to the application of theory and practice of wireless remote receiver system to study. The main contents include the following: According to the project requirements to design wireless remote launch reception system, the corresponding hardware circuit , CODECs way to compose of structural components, and detail to described the system of hardware design ,structure and the technology of codecs control circuit. In this paper, raise to use button to achieve Multi-channel remote control design method, given the detailed design method of principle and specific design the circuit. At the same time gives a unique system of detailed measures and anti-jamming system energy-saving measures.In the circuit,the design and control methods adjust to the general simple remote control system,and also have some practical and versatile in the hardware design. The whole radio remote control system in the design leaving room for the future expansion. If need to control and use the high-voltage equipment in the future, can add torelay at the output, in order to achieve weak control strong and at the same time, can also protect the people’s security.
