Problems solved by technology

[0007] Since the ping packet test method cannot store the data during the power-on and start-up process of the train network equipment, if there is an abnormality in the start-up of the train network equipment during the test, it will be difficult to locate the start-up abnormal point, which is not conducive to the analysis of the cause of the abnormal problem
[0008] The ping packet test method can only test the start of the Ethernet communication task after the train network equipment is powered on, lacks the test of other key tasks, and has a small range of fault detection

Abstract

The invention relates to a test method for starting abnormality of a train network communication device, comprising the following steps: a test system is constructed for testing the train network communication device; a PC sends a command to a program-controlled power supply to control the program-controlled power supply to power the test system and the train network communication device; the PC collects the data during the power-on startup process of the train network communication device; the PC determines whether the power-on startup of the train network communication device is normal, if so, the test system performs initialization, and if not, the PC stores the power-on startup abnormal data of the train network communication device. The method stores the power-on startup abnormal dataof the train network communication device through the PC, so that the tester can accurately locate abnormal points and quickly find the abnormal cause according to the data stored in the abnormalityduring the subsequent analysis, thereby improving the efficiency of abnormal point positioning and abnormal cause search.

Description

technical field [0001] The invention relates to the field of rail communication equipment testing, in particular to a method for testing abnormal startup of train network communication equipment. Background technique [0002] In the current track communication test field, the test method of powering on the train network communication equipment is usually a manual test or a Ping packet test. [0003] During the manual test operation, the tester energizes the network communication equipment of the tested train to start, and monitors the power-on and start-up conditions and the start-up of various tasks. [0004] If an abnormality is detected, stop the test and analyze the abnormality; if the situation is normal, the tester manually powers off the train network communication equipment and repeats the previous test work manually. Manual testing methods have a high labor occupation rate and low testing efficiency. [0005] In the Ping packet test method, the Ping packet is writ...
