摘要
设计了一种由AT89C51和nRF401模块所构成的矿山中的信号采集和控制系统。采集的信号为温度、湿度、甲烷浓度。分别介绍了各个信号采集模块的电路图,并给出了系统的硬件原理图和软件设计方案。实验结果表明:现场指定点的信号能准确的传输到控制终端并在显示器上显示。信号超出上下限时会发出报警信号,从而对现场进行有效地控制。
A signal measure and control system is designed which is constructed with nRF401 and AT89C51. The paper describes the signal measure modules of temperature, humidity and the consistence of methane respectively. The hardware circuits and the software schemes are presented. The results indicate that the appointed signal of the field can be transmitted to the control terminal exactly. The alarms run when the signals exceed the maximum or are under the minimum.
