Automatic monitoring system for equipment room leakage based on microwave radar sensors
To further ensure the waterproofing and safety of the power network,a roof water level monitoring system based on sen-sor technology is proposed to monitor the leakage of rain in buildings.Among them,the monitoring system mainly designs three main modules:wireless sensor unit,wireless communication network,and automatic water level collection.It uses EMD based wavelet en-tropy threshold denoising algorithm to denoise the collected water level data,further improving the accuracy of the data.The experi-mental results indicate that.The designed water level monitoring system accurately monitors the roof water level,and the accuracy of describing the change trend is also high;Compared with the previous denoising method,the improved EMD denoising algorithm can achieve better denoising results,with root mean square errors of 7.15,3.33,and 1.55 under noise conditions with a signal-to-noise ratio of-1,5,and 10dB,respectively.The above results indicate that the designed roof water level monitoring system based on sen-sor technology can accurately monitor water level and make corresponding judgments on the leakage situation of buildings,which is highly feasible and can be applied in practical scenarios.
