Abstract

Traditionally, the voltage and current sampling wiring for the device of low-voltage station area acquisition and monitoring is complex. Furthermore, there are many nodes, and each node is measured by wiring, consequently safety and efficiency have to face great challenges. This paper proposes a new idea of independent voltage and current sampling, using high-precision synchronous time synchronization and high bandwidth wireless transmission technology to promote the miniaturization design of wireless metering devices and smart terminals. It is verified that the synchronous timing accuracy of less than 10us, and the high bandwidth transmission above 1Mbps can be achieved to meet the requirement of 200Kbps. The results show that the ping-pong timing mechanism and broadband wireless technology used in this paper achieve the expected effect. It will improve ubiquitous sensing, data fusion and intelligent application capabilities of distribution equipment at all levels in the future.
