Centralized traffic control (CTC) collecting board test table

Abstract

The invention discloses a centralized traffic control (CTC) collecting board test table. The centralized traffic control (CTC) collecting board test table comprises a test machine box and a computer,the test machine box is separately in communication with the computer through a network cable and a serial port line, and the test machine box is composed of a box body frame, a power supply board, asignal output board, a secondary voltage stabilization module, a logical operation board, a CTC collecting board and a bottom board. The CTC collecting board test table is developed to meet the test,overhaul, maintenance and management of the CTC collecting board and before indoor simulated test and verification of CTC station program application, the test table generates simulated signals to thecollecting board input end according to a test scheme, the CTC collecting board analyzes the simulated signals and sends a test result to the logical operation board through a controller area network(CAN) bus, detection result files of the logical operation board are read through Ethernet, comparison is carried out by combining the test scheme, and finally, a test report of the collecting boardis provided and the simulated test of a CTC station program is completed.

Description

technical field [0001] The invention belongs to the technical field of train dispatching and commanding systems, and in particular relates to a CTC acquisition board test bench. Background technique [0002] With the development of railways, CTC (train dispatching command system) is more and more widely used and more and more important. The CTC acquisition board is used to collect the interval signal machine and the track circuit switch value, and reflect the train running position on the CTC, which plays a great role in traffic command and guarantee of traffic safety. As an equipment management unit, it is our primary responsibility to ensure the normal operation of equipment. It is our important responsibility to quickly deal with equipment defects and manage software releases. Before there is no CTC acquisition board test bench, when a CTC acquisition problem occurs on site, the acquisition boards sent to the site from the electronics workshop cannot be guaranteed to be ...
