1 问题的提出 机车运行监控记录装置（以下简称“监控装置”）是一种将微型计算机控制技术应用于铁路行车安全领域的电子设备。其监控功能主要针对线路运行,但在库内作业,仍然是个空白点。为此我们研究开发了利用机车监控装置,通过加装库内地面显示信号和道岔前方移频发码环线,实现对铁路库内无连锁道岔的有效防护。2 库内防止挤道岔的设计思想 机车乘务员按照地面信号的显示,进行出库作业。机车径路中,所有道岔的顺向正确时,地面信号显示绿灯,地面环线同时发绿灯码,机车信号接收到地面环线绿灯发码后,监控装置语音提示“绿灯通过”。即允许机车出库作业。机车径路中,当有一副道岔的顺向不正
1 PROBLEM PROBLEM The locomotive operation monitoring and recording device (hereinafter referred to as “monitoring device”) is an electronic device that applies microcomputer control technology to the field of railway traffic safety. Its monitoring function is mainly for line operation, but homework in the library is still a blank point. To this end, we research and develop the use of locomotive monitoring device, through the installation of the display signal in the ground and the front of the switch shift frequency code ring, to achieve effective protection of the railway library without chain turnout. 2 library design to prevent crowded turnout locomotive crew in accordance with the ground signal display, a library operation. Locomotive route, all the turnout is correct, the ground signal shows green, the ground loop at the same time the green light code, the locomotive signal received by the ground ring green light code, the monitoring device voice prompt “green light.” That is to allow the locomotive out of operation. Locomotive route, when a turnout of the forward is not correct
