为提高新建变电站遥信双边表的对试效率，设计了一种串口报文信号试验端子排。该装置采用LED灯显示当前接收到的串口报文信号的状态，并能同步播放该信号内容的提示语音；能够模拟调度主站的基本通信功能，满足新建变电站在远动通道不具备条件时的离线调试要求，即全部信号被正确试验至本装置上的LED灯后，该站与调度主站间的遥信对试可通过操作本装置上的信号重现按键触发串口检修报文来完成。

Abstract: To improve the test efficiency of teleindication between a new substation and master stations, a new type serial protocol test terminal board is designed.Firstly,LED is used to show the status of the received signal and a prompt voice of the signal content can be simultaneously played. Secondly, basic communication function of the master station can be simulated, so simulation test of a new substation without telecontrol channel can be carried out. Thirdly, the device can be used in teleindication test between a new substation and many master stations by operating the buttons on it to generate signal’s maintenance message after all signals are correctly tested to the LEDs on it.

由于受OPGW施工进度的影响，新建变电站至调度主站的远动通道形成时间往往临近变电站的送电时间，且220 kV及以上电压等级的变电站需要与多个调度主站通信，1个调度主站甚至有多套调度自动化系统需要进行人工设置遥信双边表的校核，由于信号量大且调试时间不充分，运维人员在变电站现场验收时只能抽检部分信号进行对试，这种做法给变电站的安全运行留下隐患。如何提高新建变电站与调度主站间遥信双边表的对试效率，缩短在线调试时间成为当下急需解决的问题。文献 [1]谈到了开发仿真设备进行自动化设备对点调试的迫切性和重要性，文献[2]提到了检修人员利用对点软件完成与各监……
