Embodiment Construction

[0042] As mentioned in the background technology, imported LEU equipment is usually tested in a test environment built with separate equipment (tooling) such as DC power supplies, oscilloscopes, and switches. Therefore, the test environment built for testing imported LEU equipment cannot be applied to the testing of self-owned LEU equipment.

[0043] In view of this, the embodiment of the present application provides a test system for LEU equipment, which is used to test the LEU equipment to be tested. The test system for the LEU equipment includes: a control module, a function module and a communication group box; wherein,

[0044] The control module is configured to determine a test mode according to an input command, and transmit a control command to the functional module according to the test mode or transmit a default message to the LEU device under test according to the test mode; and for receiving The feedback signal of the LEU device to be tested is analyzed, and a tes...

Abstract

The present application discloses a test system for LEU equipment. The test system for LEU equipment is composed of a control module, a function module and a communication group box. The function module includes a communication module, an impedance module, a switch module and an acquisition module. The communication group box cooperates with the communication module to realize the communication between the control module and the LEU device to be tested, and the control module and the functional module perform signal simulation and feedback signals in different test modes according to the application scenarios and working environments of the LEU device to be tested In order to achieve the acquisition of test records in different test modes, meet the test requirements of independent LEU equipment, and then realize the purpose of performing various tests for independent LEU equipment.

Description

technical field [0001] The present application relates to the technical field of railway signal testing, and more specifically, relates to a testing system for LEU equipment. Background technique [0002] LEU (Lineside Electronic Unit) is an important part of my country's train control system, which provides an interface between the signaling system and the transponder, and transmits line information to the active transponder. [0003] At present, railway engineers independently design and develop independent LEU equipment in order to achieve the purpose of replacing imported LEU equipment with independent LEU equipment. Before the self-owned LEU equipment is put into use, it is usually necessary to use the test system of the LEU equipment to test it, but the current LEU equipment test system is mainly aimed at the test of imported LEU equipment, and cannot realize the test of the self-owned LEU equipment. Therefore, provide How to design a test system for autonomous LEU eq...
