摘要
针对当前RTU监控系统实时性较差的问题,设计了一个基于GPRS的RTU监控系统。GPRS(General Packet Radio Service通用分组无线业务)具有传输速率高、实时在线、覆盖范围广、按流量计费等特点,不仅可以满足RTU监控系统实时性的要求,而且节约成本、可靠性高。并且可以有效地避免由有线方式传输报警数据带来的多种问题。该监控系统由下位机和上位机两部分组成,下位机硬件以单片机ATmega128作为控制核心,辅之以内置TCP/IP传输协议的GPRS模块WISMO Quik Q2406B实现对RTU的监控以及报警信息的无线传输。软件部分采用Code Vision AVR C语言开发设计;上位机软件采用Visual C++6.0开发设计,具有菜单操作、屏幕显示和声光报警等功能。实际应用表明该系统可以很好地满足系统的实时性要求,达到了预期的目标。该系统为无人值守的系统开发提供了许多可借鉴的宝贵经验,具有广阔的发展前景。
A substation RTU monitoring system based on GPRS is designed to meet the real-time requirement of power system.General Packet Radio Service(GPRS) has many features such as high transsmion speed,real time online,wide coverage area and accounting according to flow,which can not only meet the real-time requirement of RTU monitoring system but also has low cost and high reliability.It can effectively avoid many problems caused by transmitting alarm data using wire.The system is composed of host computer and lower computer. In the lower computer,taking the single chip microprocessor of ATmega128 as the core and the GPRS module WISMO QuikQ2406B including inner TCP/IP protocol as the complements,the acquisition and processing of the remote control data and the transmission of alarm message is completed.The software part of the lower computer is designed by Code Vision AVR C.The software part of the monitoring center is realized by Borland C++ Builder 6.0,which has functions of menu operation,screen display and sound light alarm.It is proved that this system can well meet the real-time requirement in practical application,which has achieved the anticipated goal.It offers valuable experience for other unmanned watched system and has wide developing prospect.
