Abstract

The invention provides a motor train unit end signal test method. The method includes the steps that a drawing is analyzed, so that end variables are analyzed and collected; an end simulator is manufactured, the input variable and the output variable of the end simulator are defined, an input and output control principle diagram of the end simulator is drawn, and an input switch, an output switch and the type of a lamp are selected; the end simulation input variable and the end simulation output variable are defined, wherein the input variable and the output variable are defined by end control signals according to a train logic diagram and a principle diagram; an end simulation variable test is conducted, wherein according to all system control logic requirements, input and output of the end simulation variables are conducted. The motor train unit end signal test method is easy and convenient to operate and a test result is reliable and stable; single train routine testing work hours are reduced by operation and the routine testing work hours are reduced by about 120 hours for each train compared with the background technology; by the adoption of the method, description is convenient when a technician compiles a routine testing schedule and the switches / the lamp are directly used for replacing unnecessary details of the signals; understanding and memory are facilitated, an operator only memorizes the switches / the lamp and does not need to memorize the complex signals and related description of the signals.

Description

technical field [0001] The invention relates to a test technology for signals at the end of an EMU, which simulates and realizes the functions of vehicles in a connected state. Background technique [0002] At present, the EMU end signal test uses short-term analog input and output. The operator looks at the 46-pin adapter for a long time, which will cause visual fatigue, and may simulate wrong input and output, causing damage to the vehicle and the operator itself. Moreover, the operation is complicated. It takes two people a day to test a car, and the test is not intuitive. Contents of the invention [0003] What the present invention aims to solve are the problems of time-consuming and labor-intensive and unreliable testing existing in the current technical situation, so as to improve production efficiency and reliable testing. [0004] In order to solve the above-mentioned technical problems, the present invention provides a kind of EMU terminal signal test method, it...
