Setting method of rear axle counting point of turnout section of urban rail transit signal system

Abstract

The invention relates to a method for setting an axle counting point behind a turnout in a turnout section of an urban rail transit signal system. The rear axle counting point of the turnout set by the method is outside the position of the warning mark of the turnout, and the rear axle counting point of the turnout reaches the warning mark The distance is equal to the set distance. Compared with the prior art, the present invention has the advantages of both operational safety and operational efficiency.

Description

technical field [0001] The invention relates to an urban rail traffic signal system, in particular to a method for setting axle counting points after a turnout in a turnout section of an urban rail traffic signal system. Background technique [0002] Urban rail transit has the characteristics of large volume, fast speed, safety, punctuality, environmental protection, energy saving, etc.; construction and operation are started in more and more large and medium cities; in the process of urban rail transit construction, the platform is often determined in the civil construction stage. , the position of the switch, and then the signal system sets the section, signal machine, transponder position, etc. according to the platform and the position of the switch; the setting effect directly affects the safety and efficiency of train operation. [0003] During the running process of the train, after passing the turnout (from the front of the turnout to the back of the turnout), accord...

Problems solved by technology

[0003] During the operation of the train, after passing the turnout (from the front of the turnout to the back of the turnout), according to the interlocking logic, in general, when the turnout is not intruded (the counting point behind the turnout is outside the warning mark), as long as the train leaves the turnout area section, the turnout can be unlocked for subsequent trains to use. If the follow-up train is in a different turnout direction, at this time the turnout turns to handle the route for the rear train to use. If there is a slope on the line, the front car may slip back and slip into the warning mark , and the following vehicle will cause a side collision event. In order to avoid this situation, the interlocking CI system is often required to check and clear the connected section after the turnout before unlocking the turnout. However, this will affect the operating efficiency and cause train intervals. too long
