设计并实现了基于无线射频技术的多传感器数据采集系统。详细阐述了系统的实现原理和方法。系统下位机采用集成温湿度传感器SHT71、烟雾传感器MQ-2和模数转换器ADC0832完成数据采集,并通过无线收发模块nRF905发送;上位机利用无线收发模块nRF905接收数据并通过串口传送给PC机进行实时监测。系统电路结构简单,工作稳定可靠,改变了传统线缆直连实现信号传输的方式,极大地提高了设备应用的灵活性并且可以实现多种信号的采集。
Design and implementation of a multi-sensor data acquisition system based on radio frequency technology. Elaborated the system realization principle and the method in detail. The lower computer of the system uses the integrated temperature and humidity sensor SHT71, the smoke sensor MQ-2 and the analog-digital converter ADC0832 to complete the data acquisition and send it through the wireless transceiver module nRF905. The upper computer uses the wireless transceiver module nRF905 to receive the data and send it to the PC through the serial port real-time monitoring. The system circuit is simple in structure, stable and reliable in operation, and changes the way that the traditional cable is connected directly to realize the signal transmission, which greatly improves the flexibility of equipment application and can realize the collection of multiple signals.
