Problems solved by technology

The fuel cost of running the diesel engine for each test adds up to a huge cost waste
In the actual use of locomotives, due to faults caused by electrical action stuck or wrong connection when the line is restored, it often causes the main board of the monitoring device to burn out or the valve action is out of control during the routine monitoring test of the locomotive, which not only causes huge cost losses, It also disrupted the operation order of railway locomotives

Abstract

The invention introduces a simple method for testing the performance of the LKJ2000 type train operation monitoring and recording device. The signal input jack, valve and speedometer drive output jacks are short-circuited with the plug of the digital multimeter to realize the input of external power supply or feedback, simulate the output of the monitoring host, and quickly test the performance of the monitoring and recording device, effectively eliminating the possibility of wiring errors The resulting burnout of the main board maintains the normal operation order of railway locomotives, reduces manpower, reduces diesel consumption, reduces environmental pollution, and saves enterprise costs.

Description

technical field [0001] The invention belongs to the technical field of railway locomotive safety in rail transit, and in particular relates to a simple method for testing the performance of an LKJ2000 type train operation monitoring and recording device without starting the locomotive. Background technique [0002] The LKJ2000 train operation monitoring and recording device is an important part for real-time monitoring of the operation of railway locomotives, which is equivalent to the black box of an airplane and is most widely used in Chinese railway locomotives. According to the statistics of the number of locomotives owned by China Railway Corporation on December 31, 2018, there were 19,926 locomotives in the country. According to the installation of a set of LKJ2000 train operation monitoring and recording devices for each (section) locomotive, the total number of monitoring and recording devices reached 21,318 sets (19,926 +20+1182+184+6=21318), among which HXD1, DJ4, ...
