“无线采集＋电力线传输”构建新型自动抄表系统

为了避免数据采集端额外布线,又能确保数据采集的适时性和准确性,并且能够充分利用广阔的低压电力线网络,首次提出一种近距离无线数据采集与远程低压电力线传输相结合的自动抄表系统的实现方案,给出系统框图、硬件组成原理图及软件流程图。经实验测试证明该系统工作性能稳定、智能化程度高、适用性好,可以实现每单元8层楼以下的用户数据采集和500 m以上的远程传输。

New Design of Automatic Meter Reading System with "Wireless Data Acquisition and Power Line Transmission"

In order to avoid using additional wiring on data acquisition-terminal,to ensure the timeliness and accuracy of data acquisition,to take full advantage of the vast low-voltage power line network,a new design of automatic meter reading system is presented.Wireless data acquisition in short distance and low-voltage power transmission in long distance are applied in such system for the first time.The system block diagram,hardware schematics and software flow chart are given.Characterized by stable performance and a high degree of intelligence,the system has a good applicability.By testing,data acquisition under 8 floors and long-distance transmission above 500 meters can be achieved by the system.
