Embodiment Construction

[0023] combine figure 1 with figure 2 Describe this embodiment, a rail vehicle sanding control method, the method is specifically implemented by the following process:

[0024] Take the vehicle marshalling of a certain line of Chongqing Metro as an example to illustrate. The full list is a formation of 6 vehicles: "=Mc1+Mp1+M1-M2+Mp2+Mc2=", when the Mc1 vehicle is the master, the Mc1, Mp1, and M1 vehicles perform sanding; when the Mc2 vehicle is the master, the Mc2, Mp2, M2 vehicles perform sanding.

[0025] Sanding control is divided into automatic sanding and manual sanding.

[0026] Automatic sanding conditions and instruction transmission:

[0027] Braking level ≥ 85% of the maximum common braking and continuous sliding (single-axis or multi-axis) for more than 3s;

[0028] During emergency braking and coasting (single or multiple axles).

[0029] When the network system detects any one of the above two trigger conditions, the network will issue a sand spreading com...

Abstract

The invention discloses a rail vehicle sanding control method, relates to the field of rail vehicle sanding control, and solves the problems that sand is used too fast, the sand purchase cost and the manual maintenance cost are increased and the like due to an existing sanding control method.The method comprises the steps of automatic sanding and manual sanding, automatic sanding triggering conditions are set, wherein the braking level is larger than or equal to 85% of maximum service braking, and continuous sliding lasts for more than 3 s; emergency braking and a sliding state are realized; when the vehicle network system detects any one of the two triggering conditions, the network system issues a sanding instruction to control an electromagnetic valve S3 in the sanding device to carry out sanding, namely sanding is automatically triggered; manual sanding triggering conditions are set, wherein a driver presses a driver position sanding device button for sanding; a sanding instruction is directly issued through a hard wire, the electromagnetic valve S3 is controlled to carry out sanding, and manual sanding is achieved; sand can be reasonably used, the sand adding maintenance period is prolonged, and labor cost waste is reduced.

Description

technical field [0001] The invention relates to the field of rail vehicle sand spreading control, in particular to a rail vehicle sand spreading control method. Background technique [0002] When the rail vehicle is running normally, the adhesion between the wheel and rail is usually large enough, the wheel and the rail surface are in a rolling state relative to each other, and the vehicle will not slide even if the vehicle is under braking conditions. But for extreme weather such as rain and snow, the adhesion between the wheel and the rail is very low. Therefore, for rail vehicles that operate on a line with a large slope or on a line that needs to be operated on the ground, it is generally necessary to configure a sanding device to realize the sanding function, so as to improve the adhesion between the wheels and rails, so that the traction or braking force of the vehicle can be sufficient. play. In order to make sand spreading more reasonable, and at the same time redu...
