基于PL3201的电力载波抄表系统开发

Development of Meter-Reading Terminal by Power Line Communication Technology based on PL3201

电力载波通信技术适用范围相当广泛,低压电力网覆盖面广,如何利用其巨大的网络资源,实现高质量的数据传输是一个世界性热点问题。另一方面,电力部门采用大量人工抄表,效率低,实时性差。针对以上问题,本文开发了基于ARM和PL3201的低压电力载波抄表终端。该终端利用低压电力网覆盖面广的优点,采用中心频率为120KHz的直序扩频方法实现对电表数据的采集,并利用GPRS网络将电表数据上传到远程主站。该终端实现了电表数据实时抄收的功能,效率高,实时性好,并节省了人力物力资源。

Power Line Communication Technology applied to a wide range of low-voltage power network coverage, how to make use of its huge network of resources, to achieve high-quality data transmission is a world-wide issue. On the other hand, the power company to adopt a large number of manual meter-reading, low efficiency, real-time difference. The light of these, the development of this paper, based on ARM, PL3201 and low-voltage power line carrier meter-reading terminal. The terminal use the advantages of low-voltage power network coverage and use the center frequency of 120KHz for direct sequence spread spectrum method of meter data collection and use of the GPRS network meter data will be uploaded to a remote master station. The terminal has functions of collecting real-time meter data, high efficiency, real-time, saving manpower and material resources.
