Abstract

The invention belongs to the field of interlocking system IO contact simulation, and discloses an interlocking system IO contact simulation device. The simulation device comprises an input simulation board, an output simulation board and a logic controller, the output simulation board is used for detecting a voltage signal outputted by the interlocking system driving board, and the input simulation board is used for generating a direct-current voltage signal for the interlocking system acquisition board to acquire the voltage signal; the logic controller is respectively connected with the input simulation board and the output simulation board, and the input simulation board and the output simulation board are connected and communicated through a bus. According to the invention, connection of IO contacts under various experiment conditions can be satisfied only by one-time line connection.

Description

technical field [0001] The invention belongs to the field of IO contact simulation of an interlocking system, in particular to an IO contact simulation device of an interlocking system. Background technique [0002] In the rail transit industry, when performing interlocking system acquisition (I) and drive (O) function tests, it is necessary to frequently perform system drive-production alignment tests and drive-production logic function verification. During the current IO test and verification, there are two requirements: a large number of contacts and frequent changes in station program data. When the number of contacts is small, test and verification can be carried out after IO wiring connection according to the specific station program data; and when the number of contacts is large, by changing the IO wiring connection to adapt to the frequently changing station program data, The work is too large to be realistic, and the wiring is prone to errors. At this time, softwa...
