General signal data recorder for cocomotive

Abstract

The general locomotive signal data recorder consists of CPU module, signal acquiring part, serial interface, isolating input part, clock chip, data storing part, memory card, radio communication function module, memory card interface, reset circuit and mode selector part. The coil signal, auxiliary information and digital signal input via the signal acquiring part, serial interface and isolated input separately are processed in the CPU module and stored with the abnormal information being transmitted via the radio communication function module to the ground monitoring workstation. The recorder can record information related to the operation of the general locomotive signal and provides technological measures for the locomotive signal worker to understand locomotive signal operation state and debugging.

Description

technical field [0001] The invention relates to a data recorder, in particular to a general-purpose locomotive signal data recorder. [0002] Universal locomotive signal is the dominant locomotive signal product in the railway, and it is the key basic equipment in the current locomotive operation safety guarantee system. In order to adapt to the rapid development of railway transportation in recent years, Article 91 of the "Railway Technical Management Regulations" issued by the Ministry of Railways of the People's Republic of China on May 1, 2000 clearly stipulates that the locomotive signal as the main locomotive signal should have a record of operating data. Function. As a functional component of the general-purpose locomotive signaling system, the recorder has comprehensively and completely recorded and processed the relevant data of the general-purpose locomotive signal operation status, providing conditions for further improving the general-purpose locomotive signal fun...

Problems solved by technology

Its shortcoming is that in the existing recorder designs, the signal processing of the receiving coil is processed by extraction (spectrum extraction or other methods) to reduce the amount of data. The general method is to extract part of the spectral line features of a specific system , record the spectral line and amplitude of the existing standard signal system (such as frequency shift and UM71), ignore factors such as power frequency harmonic interference spectrum, leakage spectrum and other factors for storage

This processing method is usually used in signal measurement, but if it is applied to locomotive signal recorder products, there are major flaws. Extracting the receiving coil signal and ignoring the so-called useless information will lose the minimum objectivity of the recorded data. and authenticity; the existing recorder does not detect and record the locomotive signal application environment information in information recording; the existing recorder cannot transmit the information to the maintenance personnel in time when an abnormality occurs during the locomotive signal application process, and can only The reading of information can only be completed by means of transcription after the locomotive has completed its operation and returned to the warehouse. The process of locomotive running to the warehouse may take several days, so the maintenance personnel cannot timely understand the abnormal situation, which may cause the locomotive signal to run with faults for a long time
