Problems solved by technology

The characteristics of long lines and large sections of large railways determine that the application of the old scheme has little effect on the efficiency of line use, while the characteristics of short lines, many vehicles, and busy operation of the subway system require that the use efficiency of lines be improved as much as possible and the operation interval be shortened. The scheme occupies a large number of track sections at one time, which is not conducive to improving operational efficiency

Embodiment Construction

[0017] Such as figure 2 As shown, the principle schematic diagram of the triggering method in the train route of the present invention.

[0018] The method for triggering the interlocking protection routes of subway vehicles in the present invention sets each protection route trigger point in the corresponding train route, and the specific steps are as follows:

[0019] The first step, the interlocking system detects the running position of the train according to the occupancy of the track circuit;

[0020] In the second step, when it is detected that the train enters a certain train route, the system makes preparations for arranging the protection route corresponding to the train route;

[0021] In the third step, the train continues to run. When it is detected that the vehicle enters the section where the trigger point of the protection route is located, the interlocking system starts the protection route;

[0022] In the fourth step, the interlocking system discharges th...

Abstract

An interlock protective route trigger method for metrovehicle provides each protective route trigger point in a corresponding train route and comprises the following specific steps: step one: an interlock system detects running position of a train according to an occupied condition of a track circuit; step two: when the train is detected to enter a train route, the system prepares a protective route with the arrangement being corresponded to the train route; step three: the train continuing running, when the train is detected to enter a zone in which the trigger point of the protective route is located, the interlock system starts the protective route; step four: the interlock discharges the protective route, and the train continues running. The interlock protective route trigger method for metrovehicle divides a zone occupied in one time into two times of occupations, then the interlock protective route trigger method for metrovehicle improves availability factor of zones and does not change the original interlock and opposite relationships, so the the interlock protective route trigger method for metrovehicle does not add extra amount of work.

Description

technical field [0001] The invention relates to a method for triggering an interlocking protection route of subway vehicles, and belongs to the technical field of interlocking systems in urban rail signals. Background technique [0002] In the traditional existing interlocking technical conditions for driving based on signal light display, in order to prevent the rushing of trains, a certain distance of the track behind the terminal signal is set as a protection zone. If the length of the first track section behind the terminal signal is not enough Set the distance, then after setting the terminal signal, the first and second sections are protection zones until the length of the protection zone is greater than or equal to the set distance. The triggering of the protection route is triggered simultaneously with the train route, and the trigger point is before the train route, that is, the protection route is arranged while the train route is arranged. See attached figure 1 ...
