A design scheme of the wireless automatic meter reading system was put forward based on the integration of ZigBee technology and GPRS/CDMA1x technology which is low-cost,low-consumption and efficient.This plan adopts the network model of three-level three-network dual-mode,the underlying network adopts RF communication technology and star network topology,to reduce the cost of the whole network.A low-cost,low-consumption solution to transform the meters was put forward,a wireless pulse remote transmission meter based on MSP430 was designed.By adopting the interrupt wake-up technology and the radio wake-up technology,the low-consumption design for the communication equipment was achieved.Destination-driven multicasting（DDMC） algorithm was applied to the automatic meter reading system,by layer clustering data fusion,the network energy consumption was reduced,and the efficiency of aggregate reading of four meters data was improved.
