Railway non-automatic blocking arrival signal machine approach section design method

Abstract

The invention relates to a railway non-automatic blocking arrival signal machine approach section design method. The method includes the following steps that S1, non-automatic blocking arrival signal machine approach section length calculation takes service braking distance and additional quantity of a train from the highest speed to 0 into consideration; S2, an approach section range is designed by means of a same code sequence, and requirements of limiting length are segmented according to a rail circuit; S3, a locomotive signal switch-on standard is arranged at an entrance of an approach section, and a prediction signal machine is arranged on the position, 100-400 m away from the entrance, of the inner side of the entrance of the approach section. By means of the method of using the maximum service braking for calculating the approach section length, unnecessary braking of the locomotive improved according to LKJ setting regulations in the semi-automatic and automatic blocking between stations is avoided, and driving stability and driving efficiency are improved. Besides, approach section rail and code sequence division does not need to take constraints of grade braking into consideration, driving calculation is easier, and approach section rail and code sequence division is more flexible.

Description

technical field [0001] The invention relates to the field of railway signals, and more specifically relates to a method for designing an approach section of a railway non-automatic block approach signal machine. Background technique [0002] Railway non-automatic blocking includes semi-automatic and automatic non-automatic blocking. According to the "Railway Signal Design Specifications" (TB 10007-2006, hereinafter referred to as the "Signal Design Regulations") and "Speed-up Semi-automatic Blocking Section Approaching Signal Design Principles (Provisional)" (Yunji Signal [2005] No. 111, hereinafter referred to as Document No. 111 ), the current non-automatic block approach section design is divided into two types: [0003] 1) For lines with a speed of less than 120km / h, the length of the approaching section is considered according to the emergency braking distance plus a certain margin, generally 1000-1400m; The distance is 800-1000m; when the display distance of the fore...

Problems solved by technology

"From these rules and regulations, it can be seen that the locomotive signal and LKJ have become important auxiliary means for drivers to drive, and the train is allowed to run at a very low speed when the equipment fails.
