基于GSM/GPRS的家用太阳能热水器远程监控系统设计

Remote Monitoring System of Household Solar Water Heater Based on the GSM/GPRS

基于GSM/GPRS技术,设计了一种家用太阳能热水器远程监控系统,给出系统总体方案及硬、软件设计,阐述了控制仪表和通信模块之间的自定义通信协议.该系统由现场控制器、移动用户终端和企业数据中心三部分组成.其中,现场控制器采用控制仪表和通信模块双处理器结构,提高了系统的可靠性;移动用户终端和企业数据中心为系统提供多种远程监控方式,实现了家用太阳能热水器的网络化管理.调试、测试和试运行结果表明,系统稳定可靠,性能良好.用户可以通过手机短信查询和控制热水器的工作状态;热水器发生故障时,主动向用户发送手机报警短信;用户可通过GPRS网络向企业数据中心发送热水器实时状态数据,获得远程技术支持.

A kind of remote monitoring system based on GSM/GPRS for household solar water heater is proposed. The general design scheme, hardware and software design of the remote monitoring system are introduced, and the communication protocol is further discussed. The remote monitoring system consists of field controller, mobile user terminals and enterprise data center. In order to improve the reliability of system, the mode of dual MCU is adopted in field controller. Multiple remote monitoring methods are provided by the user terminal and enterprise data center, which can realize the network management of household solar water heater. Test and trial operation results show that the system is excellent in both stability and performance. When failures happen, the system will be promptly sent alarming message to your cell phone, users can also send text message at any time commanding queries the current state of the water heater. Furthermore, this system can gain access to enterprise data center through GPRS client to obtain real-time data and receive remote technical supports.
