Problems solved by technology

[0003] During the operation of the train, after passing the turnout (from the back of the turnout to the front of the turnout), according to the interlocking logic, in general, as long as the train clears the turnout section, the turnout can be unlocked for subsequent trains to use, such as the subsequent trains are running in different directions , the turnout needs to be rotated at this time. If there is a slope on the line, the train may slip backwards. When it slips to the tip of the fork, the turnout may be squeezed, causing the train to derail. To avoid this situation, the interlocking CI system is often required to unlock the turnout Before the inspection, the connected section before the turnout is cleared, but this will affect the operation efficiency and cause the train interval to be too long

specific Embodiment

[0041] like figure 1 It is the layout point of the axle counting in front of the turnout of the turnout section in the non-terminal turnout area of ​​the present invention, figure 2 It is the arrangement point of the axle counting in front of the turnout of the turnout area in the terminal turnout area of ​​the present invention.

[0042] 1. For typical non-terminal reentry areas such as figure 1 , the non-fork section G01 is composed of axle counting points JZ01 and JZ04, and the turnout section G02 is composed of axle counting points JZ01, JZ02 and JZ03; the preceding train A runs from DA to DC through the turnout P10, and the rear train B is ready to start from DB After the turnout P10 runs DC, JIZ01 is the axle counting point before the turnout, and JIZ02 and JZ03 are the axle counting points after the turnout.

[0043] 2. The deadlock distance D1 of the turnout, that is, the distance from the front pivot point JZ01 to the fork tip P10, is equal to the sum of the back s...

Abstract

The invention relates to a method for setting a front-fork pivot point in a turnout section of an urban rail traffic signal system, wherein the set distance from the front-fork pivot point to the fork tip is equal to a set distance. Compared with the prior art, the present invention has the advantages of shortening the interval time between trains and improving operation efficiency.

Description

technical field [0001] The invention relates to an urban rail traffic signal system, in particular to a method for setting an axle counting point in front of a turnout of 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, and energy saving; construction and operation are started in more and more large and medium-sized cities; in the process of urban rail transit construction, the location of platforms and turnouts is generally determined at the civil construction stage. Then, the signal system is set according to the platform and the position of the turnout for sections, signals, transponders, etc. 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 back to the front of the turnout), according to the interlo...
