Problems solved by technology

Therefore, during the commissioning process of the whole vehicle, the commissioning of various equipment cannot be synchronized with power transmission and power failure. At present, for the commissioning of the network monitoring system installed in the rail vehicle, the assembly site cannot provide special equipment for commissioning the network monitoring system. System testing tool, therefore, the debugging of the network monitoring system can only be carried out after the unified power transmission, which brings inconvenience to the debugging of the network monitoring system

Abstract

The invention discloses a board card test device, which comprises a physical interface unit and a control unit, wherein an inserting connection hole is formed in the physical interface unit; an insertion core of a board card to be tested is inserted into the inserting connection hole; the control unit is connected with the physical interface unit and used for testing the board card to be tested according to a test program which is locally set; and the control unit is in data communication with the board card to be tested in the test process. The board card test device can be used for testing whether the communication of the board card is normal. The board card test device is easy to operate and particularly applicable to a debugging scene of a railway vehicle so as to test the board card in a network monitoring system in the railway vehicle before energization; complicated equipment is not required; and a simple and effective scene test tool is provided for elimination of faults of the board card before the energization of the network monitoring system.

Description

technical field [0001] The invention relates to circuit board testing technology, in particular to a board card testing device. Background technique [0002] At present, in order to ensure the safe operation of rail vehicles, a network monitoring system is usually installed in the rail vehicles as an important part of the security equipment of the rail vehicles to monitor the safety of the rail vehicles. [0003] The existing network monitoring system adopts modularization, building blocks, and hierarchical design methods, and its structure mainly includes three parts: an information processing center unit, an input and output (IO) unit, and a display unit. Each part is composed of corresponding general-purpose boards, and each board constitutes the smallest subunit of the system. The types of boards mainly include digital input and output boards, acquisition boards, and gateway boards. [0004] The assembly of various equipment on the rail vehicle is completed by the main ...
