Abstract

The invention discloses a device for detecting fault of a single module of a CCBII brake. The device comprises an operating platform, a detection platform and a power supply cabinet, and is applicable to quick fault detection and overhaul of a locomotive brake device. The device designs a test air circuit board for comprehensively simulating an air pipeline of a locomotive brake system, a LONWORKS data communication environment under the whole working condition, high-reliability electrical characteristic parameters and complete test procedure, can comprehensively simulate the working environment and the air pipeline of the CCBII brake and can comprehensively test the network control performance, the air pipeline performance and the electrical performance of each suspicious module so as to judge whether the modules meet the on-board requirement. The device provides various test methods such as parameter arrangement, fatigue test and the like for testing the single module of the CCBII brake, can flexibly process various modules to be tested, solves the problems of long returned maintenance period, high maintenance cost, high module erroneous judgment ratio and the like, and has a good application prospect.

Description

technical field [0001] The invention relates to a detection device used in the field of fault detection of a railway train brake, in particular to a single module fault detection device of a CCBII brake. Background technique [0002] As the daily number of 20,000-ton locomotives gradually increases, ensuring the safe operation of locomotives is one of the most important tasks. [0003] CCBII brakes, which are widely used in SS4G / HXD1 locomotives as the current main model, have the design characteristics of modularization, networking and intelligence. How to ensure the safe operation of CCBII brakes is an urgent problem related to train operation safety. question. At present, the domestic research on CCBII brakes and testing and maintenance devices are still blank. When each module of the brakes fails, it needs to be returned to the factory for repairs, resulting in long maintenance cycles, high maintenance costs, and high module misjudgment rates. The department's spare pa...
