摘要:本论文介绍了一个比较容易实现,抗干扰能力较强的无线多路密码遥控系统,该系统由于采用了编码解码芯片,使其传输的信息不易受到外界的干扰,可以对远处四路电器进行遥控或报警,使用调频方式,频率选在50MHZ附近,编码组数大于10万组。该系统采用集成电路设计的收发系统,发射功率大于2mW,接收灵敏度优于50uV,发收距离大于50米。编解码芯片使用的是VD5026和VD5027,接收端接收电路使用TA7792P FM接收专用芯片。

The coded wireless multichannel remote control system
Abstract:This thesis has introduced quite is easy to realize, the wireless password remote control system of multichannel of external interference with stronger ability , because system this has used the code decode chip, make information that transmit is difficult to be interfering with external, can carry on the remote control to the distant place four groups electric appliances or report to the police, use the frequency modulation way,frequency is selected near 50MHZ,the code group number is bigger than 100,000 groups. This system uses the receiving and dispatching system which the integrated circuit designs, the emissive power is bigger than 2mW, The receiving sensitivity surpasses 50uV, sends and receives the distance to be bigger than 50 meters. Arranges the decoding chip use is VD5026 and VD5027, The receiving end accepting circuit uses TA7792P FM to receive the special-purpose chip.
