摘要： 针对城市燃气管道泄漏问题，提出了一种基于RSSI算法的城市燃气管道泄漏检测与定位技术。该技术可以分析和计算管道泄漏时ZigBee 节点之间接收信号的强度，并最终获得泄漏的位置。首先利用泄漏目标点到各接受点之间的RSSI 信号强度值确立算法模型，其次通过模型得出泄漏点到各接收点之间的距离，最后通过最小二乘法获得泄漏点的近似坐标。仿真结果显示，提出的算法具有较高的定位精度和广泛的应用前景。

Abstract: Abstract:Aiming at the problem of city gas pipeline leakage, this paper proposes a city gas pipeline network leakage and location technology based on RSSI algorithm. The algorithm analyzes and calculates the strength of the received signal between ZigBee nodes when the pipeline leaks, and finally obtains the location of the leak point. First, the algorithm model is established by using the RSSI signal strength value between the leakage target point and each receiving point, then the distance between the leakage point and each receiving point is obtained through the model, and finally the precise coordinate positioning calculation is obtained by the least square method. Simulation experiment results show that the algorithm proposed in this paper has high positioning accuracy and a wide range of applications.
