Embodiment Construction
[0040] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0041] In the urban rail transit control system, the urban rail interlocking control display communicates with the interlocking logic department, and receives the data sent by the interlocking dual system for the station display. At the same time, the MMI device sends various operation commands through the internal communication networ...

The embodiment of the present invention provides a method and device for reverse cutting of urban rail interlocking control display, the method includes: according to the communication requirements of the urban rail interlocking control display dual machine and the external interface system, the urban rail interlocking system Each external interface system is prioritized to obtain the prioritized external interface system; based on the prioritized external interface system, according to the calculation rules of the expected results of the interface system, the urban rail interlocking control display dual machine is obtained at each external interface The expected main-standby state under the influence of the system; according to the current master-standby state of the urban rail interlocking control-display dual-machine and the expected main-standby state, the master-standby switching of the urban rail interlocking control-display dual-machine is performed. The embodiment of the present invention can take into account the influence of all external interface systems on the master-standby switchover logic of the control display, and when the external interface system needs to change the degree of influence on the master-standby switchover of the control display, the expected result calculation rule of the interface system can Rapid expansion and convenient maintenance.
Description
technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a reverse cutting method and device for urban rail interlocking control display. Background technique [0002] The interlocking control display (Manual Machine Interaction, MMI) of urban rail transit, referred to as the control display, has a redundant design. The function realization and operation mode of the two MMI devices are exactly the same. In the normal operation state, the two MMI devices Online at the same time, each with independent display and operation equipment, the interlocking logic department can process the command data sent from two MMI equipment at the same time, and send various types of station and yard information to the two MMI equipment through the internal network at the same time. It realizes the interface communication function with the interlocking logic department, the automatic train monitoring system (Automatic Train Supervision, ATS), t...
