Infrared remote control device with small size, low power consumption, strong function, low cost, is widely used in the short distance wireless communication and remote control method. In order to meet the industrial and agricultural production of motor speed in real time measurement and control requirements, the infrared remote control electric steering system design and research, a detailed analysis of the various functional modules of the hardware circuit design and software programming This design mainly includes the infrared signal transceiver, LED indicator, DC motor steering control of some important modules. Based on the infrared remote control working principle analysis, based on the single-chip AT89C51coding, decoding, design of the infrared remote control circuit, prepared by the infrared transmitting and receiving procedures; in DC motor steering control, the design used for DC motor positive and negative level control to achieve motor steering control; through the infrared remote control device can also control the DC motor start and stop. This design uses the MCU infrared remote control motor steering system, the main control procedures to achieve the DC motor is transferred, reverse, stop, start four running state control, simple structure, powerful function, reliable operation, good control of motor steering.
