采用了无线传感器网络技术的楼宇控制系统可以实现目标分布的监测,从而实现照明控制、空调控制、防火监控以及智能保安等应用.实际应用中,无线传感器网络的多径效应对传感器的接收的信号强度指示(RSSI)读数准确性有严重的影响.为解决此问题,引入经验累计分布函数(ECDF)方法,使用条件概率和电子地图两种方法处理无线传感器的数据并给出目标分布结果.经过室内实验数据训练ECDF,测试结果表明,使用此方法判断目标分布鲁棒性强,准确率高.

With Wireless Sensor Network (WSN) technology,building automation system monitors the occupant distribution,so as to realize the light control,Heating,Ventilation and Air Conditioning,fireproofing and intelligent security. Multi-path effects of WSN influence the RSSI (Received Signal Strength Indication) accuracy seriously in some applications. To resolve this problem,ECDF (Empirical Cumulative Distribution Function) method was introduced in this paper. Through the conditional probability and radio map method,ECDF processed the data and prsented the distribution results. By training ECDF with indoor sensor data,the results indicate this method determines the occupant distribution effectively and robustly.
