基于ZigBee的阶梯式分时计费电能表的设计

Design of ladder-style and multi-rate watt-hour meter based on ZigBee

为贯彻国家实施的阶梯式电价政策,兼顾某电力公司实行的分时电价措施,设计了一种基于ZigBee技术的阶梯电价与分时计费电能表。电能表采用低功耗微控制器MSP430FE427实现阶梯式电价与分时计费,同时结合低功耗2.4 GHz射频系统单芯片CC2430实现无线抄表。解析了ZigBee协议栈的体系结构和Z-Stack协议栈的OSAL机制,给出了电能计费的程序设计。多功能电表作为ZigBee网络的终端节点,易于快速加入无线自动抄电表系统中,提高了抄表的准确性和效率。

The ladder-style and time-of-use pricing meter based on ZigBee was designed in order to implement the ladder electricity price policy and to take into account a power company＇s measure of the peak-valley time-of-use tariff.The low-power micro-controller MSP430FE427 was adopted in the energy meter to implement the ladder-style and time-of-use pricing,and to realize wireless meter reading together with low-power chip CC2430 in 2.4 GHz radio frequency system.After the architecture of ZigBee protocol stack and the work flow of OSAL（operating system abstraction layer） were analyzed,the programme design of electricity metering was presented.As the terminal nodes of ZigBee network,the multi-function meters could join the wireless meter reading system quickly,and improve the accuracy and efficiency of the meter reading.
