太阳电池道口自动信号测试分析会议于1983年3月在玉门召开。全路有18个单位,43名代表参加会议。会议期间听取了道口自动信号研制小组对兰新铁路两处道口自动信号设备研制情况的汇报,并组成太阳电池电源和道口自动信号设备两个测试小组对设备进行了综合测试。经过测试分析和充分讨论,一致认为:太阳电池道口自动信号设备是解决无交流电源地 Solar cell crossing automatic signal test analysis meeting was held in Yumen in March 1983. There are 18 units throughout the road, 43 delegates attend the meeting. During the meeting, he heard the report of automatic signal development team at crossing level reporting the development of automatic signal equipment at two crossing points of Lan-Xin Railway and composed two test teams of solar battery power supply and crossing automatic signal equipment to comprehensively test the equipment. After testing and analysis and full discussion, agreed that: automatic signal crossing solar cell equipment is to solve the problem without AC power
