A method for testing remote train network communication interface

Abstract

This disclosure provides a remote train network communication interface testing method, which relates to the field of train communication interface testing. Each subsystem builds a corresponding industrial network test environment according to its own equipment environment requirements; the industrial network corresponding to each subsystem and the train network control system Each node is connected to the public network gateway through its own gateway, and all nodes establish a virtual local area network on the public network through their respective gateways for data transmission; any node receives data sent by other nodes for judgment and filtering, and obtains data that meets the corresponding system of the node; The systems send signals to each other, and the test communication interface builds an industrial network test environment through each subsystem, and then accesses the public network through the master node, and cooperates with the train network control system connected to the public network through the master node to build a virtual local area network with the public network at the top , The lower layer is the network structure of the industrial network, which supports remote testing and meets the existing requirements for testing the communication interface of the train network.

Description

technical field [0001] The disclosure relates to the field of train communication interface testing, in particular to a method for testing remote train network communication interfaces. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The train network control system (TCMS) is one of the core systems of rail transit vehicles. The train traction system, brake system, and door system are all connected to the TCMS bus as its subsystems, and are managed and controlled by the vehicle control unit to form a Complex on-board industrial computer network. In TCMS, the vehicle control unit is provided by the TCMS manufacturer as the main node of the network, and others such as the traction control unit, brake control unit, door control unit, etc. node. These sub-nodes need to interact with various data information, such as train traction data, b...

AI Technical Summary

Problems solved by technology

[0006] The inventors found that the current traditional TCMS communication interface testing method faces difficulties in time coordination, the incomplete external environment of the communication equipment leads to inconsistencies between the partial test and the actual system test status, the environmental conditions of the test site affect the communication equipment, and it is difficult to carry out all access There are various problems such as system integration testing; there are usually more than 6 participating manufacturers in the TCMS communication interface testing, and the coordination of testing work among multiple manufacturers is relatively difficult, which has a great impact on the efficiency of testing work; because peripheral equipment is difficult to carry, During the test, the peripheral environment of the communication equipment is not complete enough, and the test environment of the test site is difficult to be consistent with the operating environment required by the communication equipment of each manufacturer, which has an adverse effect on the test results and is difficult to meet the existing requirements for network communication interface testing.
