A simulation test system and method based on io dual acquisition

Abstract

The embodiment of the present invention provides a simulation test system and method based on IO dual acquisition, the system includes: simulation interlocking machine, simulation IO control unit, simulation relay combination frame, simulation trackside equipment and simulation train; wherein, simulation interlocking The machine collects the real track occupancy state and the simulated trackside occupancy state at the same time, sends a drive command to the simulated IO control unit to collect the simulated relay state from the simulated relay combination rack through the simulated IO control unit, and passes the real state of the existing computer interlocking system The IO control unit collects the real relay status from the field relay combination rack of the existing computer interlocking system. The invention can satisfy the normal operation operation under the premise of satisfying the system requirements, and at the same time satisfy the on-site simulation test of the train, thereby improving the availability of the system.

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
