摘要
微功率无线自组网技术作为一种面向自动化和无线控制的双向无线通信新技术,具有近距离、低功耗、低数据速率、低复杂度、低成本等特点,而且网络容量大、时延短、安全、可靠。介绍了微功率无线抄表系统的工作原理和关键技术,设计了一种基于微功率无线技术和RS-485通信标准的无线抄表系统,编写了相关软件,实现了无线数据转发以及自动抄表功能。该系统具有成本低、组网快、稳定性高、可扩展性好等优点,现场应用结果表明,该抄表系统的设计是成功和有效的。
In recent years, micro-power wireless ad-hoc network technology is a kind of bidirectional wireless communications technology for automatic and wireless control. It has features of close quarters, low power consumption, low data rate, low complexity, low cost, and of great capacity, short delay, safety and reliability of the network. The paper introduces the principles and key technologies of micro-power wireless AMR（ automatic meter reading） system. A wireless AMR system based on micro-power wireless technology and RS 485 communication standard is designed, of which the corresponding software is programmed to realize the wireless transmission and automatic meter reading. The system designed has low cost, high networking speed, high reliability and good extensibility. Application shows the system designed is successful and effective.
