摘要

随着电子技术的飞速发展，新型大规模遥控集成电路的不断出现，使得遥控技术有了日新月异的发展。遥控装置的中心控制部件已从早期的分立元件、集成电路逐步发展到现在的单片微型计算机，智能化程度大大提高。近年来，遥控技术在工业生产、家用电器、安全保卫以及人们的日常生活中使用越来越广泛。无线电遥控技术的诞生，起源于无线电通信技术，最初的构想是无线电报技术的建立，真空电子管的发明使得无线电技术的应用和普及很快应用在民用和军用等各个领域。自从爱迪生发明电灯以来，人类对照明电器的开启和关断控制主要使用手动机械开关。随着无线电的发展，从上个世纪60年代开始，相继出现了无线电遥控的小车。

本次设计的无线遥控车系统以STC89C52单片机为核心。主要是有发射部分、接收部分和电机控制三部分组成。无线模块nRF905通过发射频率为433MHz的无线波段来发送控制信号，通过STC89C52单片机的解码，实现控制信号的输出。电机驱动电路接到控制信号后，经过驱动芯片L298进行控制小车的电机动作。主要是有发射部分、接收部分和电机控制三部分组成。发送和接收部分是采用专用的nRF905无线模块进行数据的传输和控制的。

ABSTRACT

With the rapid development of electronic technology, the appearance of new large-scale remote control integrated circuit, remote control technology has a rapid development. The center of the remote control device control unit has been from the early separation of components, integrated circuit gradually developed to the present single chip microcomputer, intelligent degree is greatly increased. In recent years, remote control technology in industrial production, household appliances, security and People's Daily life more and more widely used. The birth of the wireless remote control technology, originated in the radio communication technology, the original idea is the establishment of a wireless telegraphy, the invention of the vacuum tube makes the application and popularity of radio technology quickly applied in civilian and military and other fields. Since Thomas Edison invented the electric light, human being turned on and off control of lighting is mainly use the manual mechanical switch. With the development of the radio, from last century 60 s, there appeared the wireless remote control car.The design of the wireless remote control car system to STC89C52 single-chip microcomputer as the core. Main is transmitting part, receiving part and motor control in three parts. NRF905 wireless module through the transmission frequency to 433 MHZ wireless band to send control signal, through the STC89C52 microcontroller decoding, for the control signal output. Motor driver circuit to control signal, after a driver chip L298 motor to control the car. Main is transmitting part, receiving part and motor control in three parts. Send and receive part adopts special nRF905 wireless module for data transmission and control.
