Abstract
As a water meter enterprises and users of clearing the sole measuring equipment in the water supply system plays an extremely important position, especially large-caliber water management, which is of paramount importance. How to strengthen the large diameter water management, improve the modernization level of management, have been plagued by water supply enterprises difficult. In order to realize the meter automatically copied and sent data, the systematic use of modular design, the use of advanced computer technology, Wireless communications technology and modern electronic technology, stratified, distribution, decentralized structure, design of the remote control meter automatic meter reading system. Papers of the meter-reading technology, wireless communications technology, SMS business development with the status quo, a detailed analysis of the meter reading system works. Based on this system, the hardware structure, software for the design and realization. System hardware subsystem mainly by users, Wireless network management subsystem and the subsystem consists of three sections. Users subsystem mainly by the Data Acquisition and Display modules, data concentrator, communications and control modules for GSM practices, achieving automatic meter data acquisition and display. Multi-user data centralized, command and control of meter data delivery, and other functions; Wireless network subsystem use the existing GSM wireless network, using the GSM network Short Message Service, meter data and to control a short season in the form of news unlimited long-distance transmission; Management Subsystem by the GSM transceiver and computer components, completion of system management and coordination meter data processing. The system includes software modules and wireless PC serial communications Dynamic Links to the application software and system interfaces three parts. Remote meter automatic meter reading system control center under the management of the collection, control commands, will be metered data messages and a form of wireless transmission network management center, users as well as the use of water under control.
