【摘要】 近年来,由于机车长交路的发展,列车运行在不同自动闭塞制式的区段上,要求有统一的机车信号。要实现机车信号通用的方法只有采用微机控制。本文是对移频制机车信号的接口、译码及输出的软件编制,以及对系统的故障—安全进行了探讨并提出了具体措施。更多还原

【Abstract】 In recent years, trains are running on different block signalling sections due to the development of long locomotive routing, which requires a new unified cab signal syetem to be designed. To meet this need, the best way of integrating various cab signal systems is to use a microcomputer. This article describes microcomputes - controlled shift - frequency cab signal system and its hardware and software concerning interface, decoding circuit,and processing program. Besides,practical measures are studied and taken to solve the "fail —safe" problems on the cab signal system.更多还原
