Portable performance testing instrument of automatic neutral-section passing control system and testing method

Abstract

The invention provides a portable performance testing instrument of an automatic neutral-section passing control system and a testing method. The testing instrument simulates states of forward operations of a I end and a II end of a locomotive and connects the states to an automatic neutral-section passing host; signal pulses conforming to input requirements of the automatic neutral-section passing host are inputted into input ports of different vehicle sensing devices to trigger outputting of a forced signal and a predictive/recovery signal of the automatic neutral-section passing host; and during the process, the sensitivity, output amplitude, output pulse width, output drive capability, and host response time of the automatic neutral-section passing host are tested. Therefore, under thecircumstance that the host does not need to be dismounted from the locomotive, the performance of the host is tested by the simple operation. Besides, the testing instrument has advantages of simplestructure, high portability, accurate measurement and fast testing speed.

Description

technical field [0001] The invention relates to the performance test of the main engine of the automatic phase transition control system of an electric locomotive, in particular to a portable automatic phase transition control system main engine performance tester and a performance test method. Background technique [0002] At present, the automatic over-phase separation method used on a large scale in my country's electrified railways is the vehicle-mounted automatic over-phase separation method with buried points on the ground as positioning information. This method is not only applied to electric locomotives with a speed of less than 160 km / h, such as HXD1C, HXD2B, etc., but also widely used in EMU locomotives with a speed of more than 160 km / h, such as CRH1 series, CRH2 series, CRH3C, CRH5, CRH380 Series and other EMU locomotives. Therefore, the automatic over-phase control system based on this method covers almost all road bureaus on the whole road. [0003] At presen...

AI Technical Summary

Problems solved by technology

The main engine operation department will stop the locomotive and notify the main engine development unit to send personnel to the site to analyze and deal with it, which increases the time cost and labor cost of troubleshooting; In order to prevent the disassembly of the on-board equipment from causing unpredictable failures to the on-board equipment, the personnel in the section are generally not allowed to disassemble the automatic over-phase splitting host

Therefore, the performance test of the automatic over-phase split main engine cannot be carried out during daily maintenance, and can only be performed when the locomotive is "raised" outside the depot. The performance test of the main engine can only be carried out when the locomotive is "repaired at all levels". The time of performance testing causes certain hidden dangers
