北京铁道学会自动化委员会无线学组于1981年11月召开了学术交流会,参加会议的有铁路科研、设计、学校和现场等16个单位97人。会上宣读的论文有:(1)电气化铁道对不同频段干扰及其干扰场强测试和数据处理;(2)小型无线电台的改进及电性能指标分析;(3)TW-8电台发射盘调测顺序的改进;(4)直流控制有线无线转接设备;(5)数字编码选择呼叫等,共八篇。会上还对铁路无线通信面临的主要问题进行了讨论,并建议; 1.学会要组织TW-8电台技术讨论会,以促进该电台在铁路运输安全方面发挥作用。目前我国铁路干线已装设TW-8电台计8,000台,约1万公里,但真正使用较好的只约1,000
Beijing Railway Society Automation Committee Wireless Group held a symposium in November 1981 to attend the meeting of railway research, design, schools and onsite 16 units 97 people. Papers read out at the conference include: (1) testing and data processing of the interference caused by electrified railway lines in different frequency bands and their interference fields; (2) the improvement of small radio stations and the analysis of electrical performance indicators; (3) Test sequence improvement; (4) DC control wired and wireless switching equipment; (5) digital coding selective call, a total of eight. At the meeting, the main problems facing railway wireless communications were also discussed and suggested. 1. The Society learned to organize TW-8 Radio Technical Symposium to promote the station’s role in railway security. At present, there are 8,000 TW-8 stations installed in our country’s railway trunk lines, about 10,000 km, but only about 1,000
