流量计远程维护系统的设计

Design of Remote Maintenance System for Flowmeters

针对流量计现场维护的困难,设计了一套通过Internet对流量计进行远程维护的系统。该系统主要由带有通信接口的现场流量计、无线通信网关和远程监控计算机组成,现场流量计和无线通信网关之间通过RS485总线进行通信,无线通信网关通过GPRS手机模块接入Internet实现和远程监控计算机之间的通信,从而实现对现场流量计的远程维护。该系统经过改进,也可用在其他设备的远程维护。

Aiming at the difficulties in the maintenance of the flowmeters, a remote flowmeter maintenance system is designed. The system is composed of the field flowmeters with self-contained communication interface, wireless communication gateway and remote supervising computer. The communication between field flowmeters is through RS485 bus, while the wireless communication gateway is connected to Internet through GPRS module of mobile phone for communicating with the remote supervisory computer. By this way, remote flowmeter maintenance is implemented. The system can also be improved to use for remote maintenance of other equipments.
