specific Embodiment

[0067] like figure 1 As shown, the industrial computer controls other boards in the NI chassis by communicating with the NI PXI-PCI 8360 board. Two PXI 8512 boards are connected to the CMU board through a 100-meter CAN transmission line, and the PXI 8431 board is connected to the CMU board for RS422 serial port communication. , PXI 6509 digital IO board is connected with MLU board for simulating fan signal, connected with CMU board for simulating train automatic control ATO signal, DATAPLUG (EEPROM) is connected with MLU and CMU board. Industrial computer, gigabit switch, simulated 100-meter-long 100M / gigabit network load board, and the tested board MLU / CMU board are connected in sequence. The upper computer software runs on the industrial computer, and the lower computer software runs on the tested board. The tested board communicates with the host computer software through the debugging network port. The industrial computer and the tested board MLU / CMU board communicate thro...

Abstract

The invention relates to an intelligent CVC-200T hardware test system and method. The test system comprises a tested board card, an NI PXI chassis, a matched board card, a network load board, an industrial computer, a Gigabit switch, a display, a keyboard mouse and a scanning gun, wherein the tested board card comprises a main logic unit MLU board and a communication management unit CMU board; theindustrial computer is an upper computer and operates an upper computer test program of NI-based visual programming software LabVIEW; the tested board card is a lower computer and operates a CVC-200Tboard card lower computer test program; the industrial computer sends a control command to the tested board card and receives test data fed back by the tested board card so as to automatically determine a test result; the display and keyboard mouse are used for human-computer interaction; and the scanning gun is used for inputting a two-dimensional code and MAC address information of the tested board card. Compared with the prior art, the system and method have the following advantages that a human-machine interface is more friendly, the operation is convenient, the development cost is reduced, the secondary development cycle is shorter and the like.

Description

technical field [0001] The invention relates to the field of railway signal equipment systems, in particular to a CVC-200T hardware intelligent testing system and method. Background technique [0002] There are many types of CVC-200T boards, and the design is extremely complex. It consists of many sub-modules.
