摘要
针对高炉、山区弯道等特殊地段限制了无线电波的传播,使正在这些地段作业的机车司机、调车人员与值班员失去语音通信,形成了无线电弱场强区和盲区,给机车运行造成安全隐患,本文提出了改造天线支架,提高设备功率的有效方案。
The special sections such as the blast furnaces and mountain curves limited the transmission of radio waves,which made the locomotive drivers and shunters lose the voice communication with attendants.So it was formed weak radio field strength areas and blind areas,which brought safe hidden trouble for locomotive running.It was proposed effective schemes to reform the antenna bracket and increase the power of equipment.
