摘要
给出一种基于GSM网络的无线压力传感器测水位系统设计。采用压阻式压力传感器和二维正交函数最小二乘拟合算法,将压力信号和温度信号互相补偿达到高精度;其次GSM网络广泛、节省人力物力成本。它能远程实时监测整个排水系统的水位,根据水位的监测结果判断路段排水情况以及及时抢修。
The system provides a kind design of wireless pressure sensor water-level measurement system based on GSM network. To reach high precision it uses piezoresistive pressure sensor and two-dimensional orthogonal least squares fitting method, so that pressure signals and temperature signals compensation to each other. The second GSM network is very broad, save manpower and material resources. It can remote monitoring the water-level of the drainage system in real-time. To timely make emergency repair according to the monitoring results of water-level road drainage condition.
