闭环电码化系统的检测原理及应用

Check principle and application of Closed Loop Telegraphic Codes System

机车信号发展到一定程度后,站内电码化就成了研究的重要课题。闭环电码化系统能够在发码的同时实时监测轨道上发码的准确性和完整性,一旦电码出现传输错误或异常,系统能进行报警。对闭环电码化系统检测原理结构、发码过程,闭环检测、可靠性等进行分析阐述,并给出部分参考电路。

With the locomotive signal developing, the telegraphic codes in railway station had become the more important study task. The system of closed loop telegraphic codes could supervise the codes＇ accuracy and completeness at the same time of system transmitting the codes, if the codes was wrong transmitted or unusual, the system would give alarm. It was discussed the check principle structure, the codes＇ transmitting, closed loop check, reliability of the Closed Loop Telegraphic Codes System with some reference circuit.
