An electric meters are used everywhere to calculate the consumption of power. Wireless meter reading technology can save human resources and another feature of this kind of meter is, it improve the accuracy since it works on real time application, enabling management sector to access to data messages within a short period of time and accurately. Due to its wireless communication network, it just not save human and material resources but this property leads to most economical meter in terms of investment. In this paper, power consumed by the consumer is monitored by base stations through wireless network. It aims to reduce the man power for billing since the meter reading is transmitted through ZigBee and at base stations we calculate bill, save records of consumers. The most important part of this project is that we can monitor any fault in meter as well as any tempering which is used to steal the electricity.

维纳噪声抑制，1、 实验原理是利用信号之间的相关性进行信号估计，从而将噪声滤除； 2、 辅助观测信号的噪声抑制可利用Wiener-Hopf方程 求出维纳滤波器的系数 ，式中 是 的自相关阵， 是输入信号 和滤波器输入 之间的互相关矢量； (Wiener noise suppression, 1, experiment is the use of the correlation between the signals for signal estimation, which will filter out the noise 2, the auxiliary noise suppression observed signal Wiener-Hopf equation can be obtained by Wiener filter coefficients, where is the autocorrelation matrix, is the input signal and filters the cross-correlation between the input vector )
