Automated Method of Checking the GATEWAYS Cells

Abstract

The rail transport in Russia plays a key role in organization of passenger transportation and transportation of goods. Security is one of the main tasks in organization of movement by railway. In locomotives systems for monitoring and controlling traffic are used to reduce the risk of emergencies. These systems include a complex locomotive safety device, which is used as a main on-board device that ensures the safety of train traffic. The complex locomotive safety device includes a GATEWAY-CAN module, designed for galvanic isolation and reconciliation of information flows of two segments of a local CAN network. The new software has been developed for GATEWAY-CAN unit, which simplifies the technique for testing the cell of the GATEWAY-CAN. The program implements: setting up CAN channels, automatically generating the necessary CAN messages and verifying the correctness of their transmission, the possibility of storing the test results in the form of a report with detailed information on the test results. The developed software makes it possible to automate the testing of the cell of the GATEWAY-CAN, which in turn leads to a reduction in time for testing the GATEWAY-CAN unit, reducing the cost of the GATEWAY-CAN unit, and also increasing the reliability of verification results.
