摘要
在工业控制领域,常常需要采集大量的数据,然后传输给主机进行处理。这些网络多基于有线传输,在使用中有很多缺点,而无线传输具有成本低、效率高、维护方便等优势。这里介绍一种以555定时器组成的电路为主体的多参数无线数据采集模块,可对温度、压力等多种参数进行采集,并分时地用同一无线信道进行传输,有着广泛的应用前景。
In the field of industrial control, it needs to collect large quantity of datum, and then sends them to host to process. These networks are mostly transmitted through wire, it also has lots of disadvantages. While, whreless transmission has characters of low cost ,high efficiency and easy maintance. This paper introduces a wireless multi - parameter data collection module/s circuit which is composed by 555 timer for the main body,it can collect the temperature,pressure and other parameters,and time- sharing carries on the transmission with the same channel. It has wide prospect of application.
