摘　　要：针对当前变电站三遥信号核对工作效率低的问题,本文研究开发一种能够实现信号单端核对的信息传输和接收系统,创新使用电力无线传输链路,突破电力内网信息传输的壁垒。利用专用服务器从主站安全获取各厂站三遥数据,通过电力接入点(APN)专网进行传输,并开发用于接收数据的移动应用,从而实现变电站三遥信号的远程获取。在信号验收过程中,无需后台人员配合,现场工作人员利用移动终端即可实现信号的单端核对。现场测试和应用表明,利用信号单端核对系统进行信号验收,现场作业人员可从五人减少到两人,单个信号的平均核对时间缩短三分之一,工作效率得到了明显提升。In order to solve the low efficiency of signal verification in substations,an information transmission and receiving system which can realize signal single-end check is researched and developed.The power wireless transmission is used innovatively to break through the barriers of information transmission in the power intranet.A dedicated server is used to securely obtain the three-remote data of each plant,which is transmitted through the special network of power access point name(APN).The mobile application for receiving the data is developed to realize the remote acquisition of the three-remote signal.In the signal acceptance process,without the cooperation of background personnel,the field staff can use the mobile terminal to realize the single-end verification.Tests and applications show that the use of single-end verification system can reduce the number of operators from five to two,shorten the average verification time of single signal by one-third,and improve work efficiency significantly.
