Research on Heat Meter Wireless Reading System in Living Area

Abstract

In order to improve the heating system's intelligence and automation level, a wireless remote meter reading system is designed based on GPRS network technology. The system consists of heat meters, collector, concentrator and remote management centers. The hardware is constructed by STM32F103MPU, wireless module, GPRS module and other components, using a combination of GPRS and wireless communications network. The software of management centers includes remote meter reading system and energy data management system, realizing the functions of remote meter reading, data query, CSV downloads, real-time monitoring and so on. The system, adopting C# and PHP hybrid programming, achieves program lock by program itself and therefore prevents database lock and also provides multi-thread meter reading. According to the test results, the system is characterized by a simple structure, low cost and a wide range of application, therefore it has a good market value and bright prospects for application.
