为了解决热泵多机组的集中管理问题,将基于通用分组无线业务(GPRS)网络的无线通信技术应用于热泵机组的远程监控中;设计了一套面向空气源热泵机组远程数据传输的GPRS无线数据传输终端。该装置采用Cortex_M3内核的高性能单片机STM32F103作为核心测控元件;采用华为GPRS模块EM310作为通信模块,完成基于TCP/IP协议的数据通信。为了提高热泵远程监控的可靠性,提出了一种针对热泵数据特点的应用层无线数据传输协议和相应的软件方案。研究结果表明,该方案具有成本低、体积小、传输速度高、布线少等特点,具有较高推广价值。

In order to solve the problem of the centralized management of multiple-unit heat pump, the wireless communication technology based on general packet radio service（GPRS） networks was applied to the remote monitoring of heat pump units, and a set of GPRS wireless data transmission terminal based on air source heat pump units was designed. High-performance microcontroller, STM32F103 was taken, which has a Cortex_M3 kernel as the core monitoring unit, and Huawei GPRS module, EM310 was taken, as the communication module to achieve the data communication function. The data communication is based on TCP / IP protocol. In order to improve the reliability of the beat pump remote monitoring, a data transfer protocol of application layer data was proposed and the corresponding software program was de- veloped. Research results show that this remote monitoring programs has features of lower cost, smaller size, higher transmission speed and less wiring. Moreover. it has high nromotion value.
