摘要
分析了无线数据收发模块的原理和数字编码、解码芯片PT2262和PT2272的性能。介绍了无线数据收发模块的3个应用实例:(1)红外控制系统;(2)多路报警电路;(3)智能体质测试仪。以报警电路的失控状态为例分析了无线数据收发模块的缺陷,提出了多频发送与接收方式、干扰报警处理和改变数字编码调制方式的3种改进方法。
It has analyzed the principle of wireless data receiving and dispatching module, the function of digital coding and decoding chip of PT2262 and PT2272. It introduces three examples of application ： （ 1 ） infrared ray control system ; （ 2 ） multi-path alarm circuits ; （ 3 ） intelligence body constitution testing instrument. It has analysed the module defect as the example of the state of being out of control of the alarm circuits. It has brought forward the three kind improvement methods：the one is multifrequency sending and receiving, another is the giving an alarm with regard to disturbed signal, the other is changing the modulation way of digital coding.
