基于GPRS的集中供热数据采集系统

针对集中供热系统数据采集的特点，应用GPRS技术，设计和实现了一种数据采集系统。GPRS（通用分组无线业务）是第二代通信系统向第三代移动通信系统平滑过度的主要方案，已日益广泛地应用于工业控制领域。介绍了系统的组成结构以及远程终端（RTU）、数据传输网络（GPRS）与数据中心（MCC）等模块的设计，分析了系统实现的关键技术和应用特点。实际运行情况表明，利用GPRS传输数据与传统的数据传输方式相比．利用GPRS传输数据与传统的数据传输方式相比，系统具有组网简单、运行成本低、永远在线、易于扩展和便于维护等优点。这种方法为行业应用中的数据传输提供了一个很好的选择。

GPRS based data acquisition system in central heating

In view of the characteristic of data acquiring in central heating project,a data acquisition system is designed and implemented,which is integrated with GPRS technology.GPRS(General Packet Radio Service) is the most important transition from the second generation communication system to the third generation communication system,and it is applied widely in the field of industry control.Then the structure and the remote terminal unit(RTU),data transmission net(GPRS)and data processing center(MCC)are designed.At last,the key technology and application characteristic of this system are analyzed.The practical operation indicates that the system has the merits of being simple to build up,low running cost,always online,easy to extend and maintain than traditional data transmission.It provides one better choice for data transmission of industry.
