Design of ladder-type intelligent meter based on ZigBee

A ladder-type intelligent meter based on ZigBee, a wireless network, is designed in order to carry out the policy of saving energy and cutting emissions in China. The energy meter uses low-power micro-controller MSP430FE427 to implement ladder-type and time-of-use pricing and to realize wireless meter reading through low-power chip CC2430. The anti-electricity-stolen function is realized by using the energy metering module ESP430CE1 which is embedded in MSP430FE427. After the architecture of ZigBee protocol stack and the work flow of operating system abstraction layer (OSAL) are analyzed, the program design of electricity metering is presented. The experimental results show that the intelligent meter can easily implement wireless transmission of data, can improve the accuracy and efficiency of the meter reading, and can intelligentize electricity supervision.
