基于NRF24L01的降雨量实时采集无线监测系统

A Real-Time Monitoring Wireless System of Rainfall Based on NRF24L01

摘要:

设计以AT89S52单片机为处理器,用集雨斗、盛水瓶、压力传感器组成数据采集模块,将采集到水的质量转换为降雨量；利用NRF24L01无线数据传输,通过串口将数据传到上位机,便于对历史降雨量的查询与研究；上位机软件采用VB进行设计,可以曲线的方式表示降雨量,自行设定降雨量的上限报警值；该系统成本低,安装方便,实现实时降雨量数据的无人采集,自动实时显示和存储,具有较大的推广价值。

Abstract:

The system uses AT89S52 as the control center,uses rain filler, filling bottle and pressure transducer as colleting module, then translate the quality of the collected water to the rainfall. In order to enhance system’s performance, it uses NRF24L01 wireless data transmission module to connect to the upper by serial ports, and provide a method to check out and research the historical volume. The upper uses VB to design a chart, and present the rainfall by diagram in curve, which can set the highest limited alarming rainfall volume automatically. The system has low cost and installs conveniently, can monitor rainfall in real-time and can display and storing data automatic, has great promotion value.
