Abstract

The invention discloses a train running monitoring record device host reliability test method. The method comprises the following steps: determining the minimum acceptable value of mean time between failures of a train running monitoring record device host; determining the test comprehensive environment conditions of the host; determining a test profile according to the test comprehensive environment conditions; testing the reliability of the host according to the test profile, and doing statistics of test data; determining whether the test is terminated according to test termination conditions, and determining whether the host is qualified or not according to the test termination processing result; and finally, estimating the mean time between failures of the train running monitoring record device host according to the test data statistics result. The technical problem on how to identify the reliability index of a train running monitoring record device host quickly and effectively can be solved.

Description

Technical field [0001] The present invention relates to the field of reliability test of rail transit equipment, and in particular to a reliability test method applied to a host of a train operation monitoring and recording device (LKJ). Background technique [0002] The train operation monitoring and recording device (hereinafter referred to as LKJ) is a train speed monitoring device developed by my country's railways with the main purpose of ensuring train operation safety. The device collects and records various locomotive operation status information related to the safe operation of the train while realizing the safety control of train speed, which promotes the automation of locomotive operation management. The train operation monitoring and recording device has the functions of monitoring, recording, displaying, alarming and data analysis of train operation. It has significant effects and significance in preventing trains from "two accidents and one overtaking" and ensuring ...
