PAGE 石家庄铁道大学四方学院毕业设计 简易无线遥控系统发射机设计 The Design of Simple Wireless Remote Control System of Transmitter 摘　要 无线遥控系统是利用无线信号对远方的各种机构进行控制的遥控设备。这种遥控技术在现代工农业生产、科研、国防等领域有非常广泛的应用。随着现代科技的发展，无线遥控技术的发展与各种设备的紧密结合，逐步促使设备向着自动化、智能化、信息化方向发展。 本设计通过无线遥控技术和单片机的相互结合设计灯光控制系统，并对系统软件设计和硬件实现进行了详细的描述，主要包括用STC89C52单片机为核心控制元件，nRF24L01芯片为无线发射模块，以1117芯片为降压模块，以独立按键为输入设备，设计一个无线遥控发射机。通过STC89C52单片机与无线发射模块nRF24L01，与降压模块1117芯片的连接，组成无线遥控发射系统。再结合软件编程，通过独立按键控制信号发射，再由无线遥控接收机接收信号，根据软件编程的设计，通过判断接收到的不同的信号，再由接收到的信号控制多个不同效果的发生和结束。 本系统运行稳定，其优点是硬件电路简单，软件功能完善，控制系统可靠，性价比较高等，具有一定的实用和参考价值。 关键词：　无线遥控系统　单片机　无线模块　流水灯　 Abstract Wireless remote control system is the use of radio signal to the various institutions for the control of the distance of the remote control equipment. The remote control technology in the modern industrial and agricultural production, scientific research, national defense and other fields have a very wide range of applications. Along with the development of modern technology science, wireless remote control the development of technology and all kinds of equipment closely, and gradually make equipment to automation, intelligence, and information development direction. This design through the wireless remote control technology and mutual combination of single chip design stage lighting control system, and the system software design and hardware realization are described, including the use STC89C52 is the control elements, nRF24L01 chips for wireless transmitting the modules to 1117 chip for bp-lowing module, independence and the buttons for input device, design a wireless remote transmitter. Through the STC89C52 and wireless transmitting nRF24L01 module, and step-down module 1117 chip connection, made up of the wireless remote control launch system. Combining software programming, through the independent button control signal emission, again by wireless remote control receiver receiving signals, according to the design of the software programming, through the judgement received different signal,
