Simulation test system and method based on IO dual acquisition

Abstract

The embodiment of the invention provides a simulation test system and method based on IO dual acquisition. The system comprises a simulated interlocking machine, a simulated IO control unit, a simulated relay combination frame, a simulated trackside device and a simulated train. The simulated interlocking machine collects an occupation state of a real station track and an occupation state of a simulated trackside simultaneously and sends a driving command to the simulated IO control unit, so that the simulated IO control unit collects the state of the simulated relay from the simulated relay combination frame; and a real IO control unit of the existing computer interlocking system collects the state of the real relay from a field relay combination frame of the existing computer interlocking system. Therefore, the normal operation working can be met on the premise that the system demand is satisfied; the field simulation testing of the train is realized; and the system availability is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of rail transit signal systems, and in particular to a simulation test system and method based on IO dual acquisition. Background technique [0002] As the operation time of rail transit continues to accumulate, the failure rate of ground equipment begins to increase, and the demand for upgrading and reconstruction of line equipment is increasing. The upgrade and transformation of the ground equipment of the operating line will inevitably involve the verification test in the transformation. [0003] At present, the existing confirmatory tests, one is carried out in the laboratory, and the other is carried out on the line. Due to the lack of a real field environment, some test cases cannot be done in the test in the laboratory, and field tests are needed for further verification. Tests carried out on the line site, or to affect the normal operation of the line, or without affecting the...

AI Technical Summary

Problems solved by technology

Tests carried out on the line site, or to affect the normal operation of the line, or without affecting the normal operation of the line (such as during night outage), need to mobilize a lot of resources of the line operator, such as trains, drivers, operation management It is not suitable for long-term experiments, and there are insufficient test cases in short-term experiments

If only a single train test is done, then the scenario of mutual influence between trains cannot be verified; if a multi-car test is to be done, the cost and the difficulty of personnel coordination will further increase
