基于单片机实现的无线遥控系统毕业论文（已处理）.docVIP

摘 要 目前，市场上的无线遥控系统每一时刻只能控制一台设备，且控制多台不能同时工作，当两个控制按键同时按下时会出现设备错误动作等问题，新设计一无线遥控系统，使其能输出8个控制信号；在控制信号发送端，可实现信号按键的优先判断；控制信号接收端可实现信号的自锁。 本设计是基于单片机实现的无线遥控系统。分为无线发射模块、无线接收模块、单片机控制部分。系统通过无线电实现控制信号的传递，单片机作为控制部件协调处理整个系统的工作，并产生相应的信号，对各种设备进行控制。选用STC89C52RC单片机，内部含Flash存储器在系统的开发过程中广泛应用于机器人和各种自动化控制领域。 关键词 无线收发系统 STC89C52RC  Abstract 本设计是基于单片机AT89S51实现的无线遥控系统。分为无线发射模块、无线接收模块、单片机控制部分和电机驱This paper is relate to wireless telecontrol system that accomplished base on miccontroller. t is composed of radio transmit module, wireless receive module, miccontrollor control section and motor driven part .本系统用无线实现控制信号的传递，单片机作为控制部件协调处理整个系统的工作，并产生相应的方向信号和PWM信号实现对直流电机的控制（正转、反转、This system transfered the control signal depend on wireless radio ,The Singlechip is a control unit take charge of processing work of total system ,and brought relevant Direction signal and PWM signal, Which can control the electromotor performed positive running ,reversal running, speedup , slowdown . The system has a strong versatility and practicality, can be used for a variety of electrical and electronic equipment in the wireless control can also be widely used in various electrical appliances, robots and various automatic control in the field of remote control devices. The system uses a 315M wireless transceiver system for wireless transmission of control signals,the wireless transmission system and strong anti-interference, transmission distance, you can achieve secure communication; drive circuit is simple, easy to control, low cost,can provide greater power, to adapt to a diverse array of automated control equipment for high-power applications. This system choose the STC89C52RC by way of controller, because it interior contain Flash memory , besides it offered download program on-line.
