Train running monitoring device comprehensive test method and comprehensive testbench

Abstract

A comprehensive testing method and testboard of train monitor device. The method is a comprehensive testing system based on computer integrated control. It adopts multi-communication mode to complete data exchange. On one hand, according to the vehicle condition simulated by comprehensive testbord, various high precision actuating signal are generated for normal working of control device, including analog, digital and communication signal. On the other hand, test various output signal of monitor device. Finally, test device by combining function relationship, board and channel grade of tested device. Three objects are communicated by computer directly, including programmed power, testboard host machine and card testing adapter. Communication from computer to programmed power and card testing adapter adopts RS232 mode, to testboard host machine adopts USB1.0 mode. Main control panel and communication management penal in testboard host machine adopts two-gate RAM to change data.

Description

technical field [0001] The invention belongs to a special detection method and equipment for an electrical system management monitoring device, in particular to a comprehensive testing method and device for an electric locomotive monitoring device; it is mainly used for testing a train operation monitoring device. Background technique [0002] The train operation monitoring and recording device is referred to as the monitoring device. It is a train speed control device whose main purpose is to ensure the safety of train operation. It is the main guarantee equipment for several large speed increases of the railway. The monitoring device widely used at this stage is the LKJ2000 train operation monitoring and recording device successfully developed in 1999. The standard configuration of the system includes a host and two displays. There are 14 pieces of 6U plug-ins in the host to form two sets of identical hot standby system. [0003] In the past, the debugging of the LKJ2000 ...

AI Technical Summary

Problems solved by technology

[0003] In the past, the debugging of the LKJ2000 monitoring and recording device has always used a portable test bench, but the focus of the portable testing bench is on the functional debugging of the entire monitoring device, but it is not possible to individually debug each plug-in of the LKJ2000 monitoring device. When maintaining each plug-in of the monitoring device, you can only insert each plug-in into the main box and observe the operation of the entire monitoring device for maintenance.

However, if you want to test the accuracy of a certain signal of a certain plug-in, you can only rely on a combination of multiple instruments to complete it, which is complicated to operate and low in reliability.
