Meter Reading Scheme Based on Automatic Switching between Two Local Communication Channels

This paper presented the meter reading scheme based on automatic switching between two local communication channels of power line carrier and micro-power wireless. Firstly, the structure of the meter reading system based on automatic switching between two local channels of power line carrier and micro-power wireless was introduced. Then two key technologies to realize this scheme which are two local channels automatic switching technology and Ad Hoc network technology are presented. The high communication success rate and accuracy of this meter reading scheme provide effective technical support for the construction of efficient, stable and practical electric energy data acquire system.
