Abstract

The invention relates to a motor infrared remote control rotating speed control system based on double singlechips, which consists of a remote control transmitting system and a remote control receiving system; and the system has the advantages that 1. the system has strong anti-interference performance, so that mutual interference can not be caused; 2. the information transmission is reliable; 3. the motor infrared remote control rotating speed control system of the singlechips with high performance can be used for realizing effective remote control for the rotating speed; and 4. remote control coding and remote control decoding scheme is suitable for controlling the rotating speed of a motor needing remote control, thus being ideal preferred scheme for self designing the control system with the function of remote control.

Description

(1) Technical field: [0001] The invention belongs to the technical field of motor speed control, and relates to an infrared remote control speed control system of a motor based on dual single-chip microcomputers. (two) background technology: [0002] Electric motors are one of the most widely used equipment in the electromechanical industry and are the source of power for other electromechanical equipment. Therefore, the speed control of the motor is very important. When the motor works in the environment of high voltage, radiation, toxic gas, dust, etc., it is not safe for personnel to control it on site. It is extremely important to control the motor with infrared remote control. It is not only completely reliable but also can effectively isolate electrical interference. Infrared remote control does not interfere with other electrical equipment; circuit debugging is simple, encoding and decoding is easy, and multi-channel remote control is possible. However, at present, ...
