摘要
针对地下配电房无网络信号或信号较差的情况,开发了GPRS延长天线解决采集终端远程通信问题。经测试,地下配电房GPRS采集终端通过该延长天线接收到的信号能够确保终端稳定上线,保证了用电信息系统的采集成功率。详细介绍了GPRS延长天线的特点、参数和测试应用情况,为用电信息采集系统的建设运维提供参考。
Aiming at the situation of no network signal or weak network signal in underground substations,developed GPRS extended antenna which solved the problems of acquisition terminal remote communication.By the test,the underground substations GPRS acquisition terminal communication was stable online through the extended antenna received signal,and ensured the acquisition success rate of electricity information acquisition system.The characteristics,parameter,test application of the GPRS antenna is introduced,for the construction and maintenance of electricity information acquisition system to provide reference.
