基于A7108的无线智能水表及组网设计

Design of the Wireless Intelligent Water Meter and Networking Based on A7108

水表在使用中为了保证计量精度,间隔几年需要更换,为了降低管理成本提高工作效率,老旧区在水表改造时更换为智能水表,实现数据的远传功能,但是老旧小区由于布线困难,给施工带来很大困难。提出一种无线智能水表的设计,按照预先设置的组网方式,完成对水表节点的组网功能以及数据的中继传输,以实现数据的远程传输。由于智能水表采用电池供电,提出解决整机低功耗的方法,延长了智能水表的使用寿命。

In order to ensure the measurement accuracy,the water meter needs to be replaced every few years. In order to reduce the management cost and improve the work efficiency,the intelligent water meter is installed to realize the remote transmission function of the data during reconstructing the old community. The wiring is difficult in the old community,so the reconstruction is very difficult,too. This paper presents a kind of design scheme of the wireless intelligent water meter. According to the preset networking mode,the networking function of the water meter node and the relay transmission of the data are completed to realize the remote data transmission. Because the intelligent water meter is powered by the battery,the method to solve the low power consumption of the whole machine is put forward,and the service life of the intelligent water meter is prolonged.
