Leakage of liquid prediction system based on wireless sensor network

为保证机房等重要场所的建筑环境安全,液体泄漏预测就显得尤为重要。本文提出一种基于无线传感网的液体泄漏预测与定位的新方法。本系统在硬件上以嵌入式单片机为核心处理器,结合无线射频模块n RF24L01,能够通过控制器将发生液体泄漏的管道快速关断,确保供水系统的可靠性与抗干扰性;在软件上采用时间片轮转法对数据进行采集,并提出一种阈值设定的新算法;最后将湿度数据经串口RS232发送到计算机进行存储与实时动态显示,实现了基于无线网的液体泄漏预测的效果。

In order to ensure the safety of the built environment, such as the engine room, the liquid leak prediction is particularly important. This paper presents a method to predict and locat leaks of liquid based on wireless sensor network（WSN）. The system is embedded in the hardware microcontroller core processor, combined with wireless RF module n RF24L01,which can quickly turn off the liquid leaking pipe by controller, to ensure the water supply system robust and credible. The round-robin method and a new algorithm set threshold have been designed in this paper. Finally the humidity data is stored in the host computer through the serial port RS232 and in a real-time dynamic display. thus a leakage of liquid prediction on the basis of wireless network can be achieved.
