摘要本课题主要是围绕无线遥控收发系统的相关理论和实践应用进行的研究。以模拟学校机房的电源管理系统作为研究,教师机通过RS-232C接口与单片机连接,有操作界面传输开关机代码至单片机。经过单片机编码后,由发射电路通过ASK调试方式垂直接地天线发射出去,再由学生机遥控电源插座装置的接收电路接受并译码。单片机识别代码后控制固态继电器执行相应的开关机动作。在这里,主要围绕AT89C2051单片机研究,发射模块是有声表面滤波器SWAF和BG2构成振荡器组成,接收模块由TDQ-3高频调谐器和双差分同步建波电路组成。为了增加可靠性,应用了目前市场上比较流行的固态继电器SSR。64799
需要额外说明的一点是,本机房电源管理系统在实际生活中需求不是很多,我们的目的是一次为基础来进行应用拓展。因为本无限多路遥控发射、接收系统通过空间传播,实现对远处受控设备的控制,受控对象很广泛也很实用,例如对工业、医疗、家用电器等设备的工作状态的无线遥控。

Title Room power Intelligent Control System Design
Abstract The main subject of wireless remote transceiver system is built around the theory and practical application of research conducted. School room to simulate the power management system as the research, teacher computer through the RS-232C interface with the microcontroller connected to a transfer switch user interface code to the microcontroller. After a chip encoded by the transmitter circuit through the ASK debug mode vertical ground antenna out, and then by the student's remote power strip receiving circuit to receive and decode. Chip identification code executes the corresponding solid-state relay control switch machine movements. Here, the main focus of AT89C2051 microcontroller, transmitter module surface acoustic wave filter is made to oscillate SWAF and BG2 composed by the receiver module TDQ-3-tuner and dual differential synchronization Jianbo circuit. For increased reliability, the application of the more popular on the market solid state relay SSR.
Additional note is that the room power management system in real life is not much demand, we aim to be a basis for application development. Because of the infinite multi-channel remote control transmitter and receiver system propagates through space, to achieve the distant control the controlled device, the controlled object is extensive and very useful, such as industrial, medical, home appliances and other equipment for Wireless Remote Control.
