Embodiment 1

[0061] An anti-skid device for passenger cars mainly includes three parts: an anti-skid controller, four anti-skid valves and four speed sensor assemblies. The shaft control method is adopted, the anti-skid valve is connected with the anti-skid controller circuit, connected with the air circuit of the brake device, and controlled by the anti-skid controller; the anti-skid controller is electrically connected with the speed sensor component, and receives the speed electrical signal of the speed sensor component . It is used to prevent the wheels from locking and sliding due to insufficient adhesion between the wheels and rails when the air brake is used during the operation of the train.

[0062] The anti-skid controller is the core component of the control system. The box body is a standard 3U chassis with three installation methods: vertical installation, horizontal installation and embedded installation. The installation method can be determined according to the actual insta...

Embodiment 2

[0088] The method and structure of embodiment two are the same as embodiment one but the selected weighted proportional coefficient is different from embodiment one, is the data obtained according to the test, and the setting coefficient is as follows:

[0089] KAS1=13.0-20.0 Wheelset speed and vehicle calculation speed difference weighting coefficient

[0090] KAS2=1.8-3.2 acceleration weighting coefficient

[0091] KAS3=4.2-7.5 Creep rate weighting coefficient

[0092] KA84=2.2-4.5 Vehicle calculation speed and vehicle speed difference weighting coefficient

[0093] KAS5=0.5-1.5 Speed ​​calculation weighting coefficient

[0094] The comprehensive index value (Z) is calculated as follows:

[0095] Z=KAS1*ΔV 轮对 +KAS3*η+KAS4*ΔV 车辆 +KAS2*α-KAS5*V 车辆计算

[0096] The control variables are explained as follows:

[0097] ΔV 轮对 Calculation of speed and wheel-to-line speed difference for the vehicle

[0098] η is the creep rate, equal to

[0099] ΔV 车辆 Compute the dif...

Abstract

An antiskid control method for train includes such steps as setting up optimal control function according to train speed and the difference between actual speed and calculated speed, evaluating the utilization of adhesion to obtain comprehensive index value, and controlling antiskid valves to increase, decrease, or hold the pressure. Its apparatus is composed of antiskid controller. 4 antiskid valves and 4 speed sensors.

Description

technical field [0001] The invention belongs to an anti-slip control method for trains, in particular to a vehicle braking control method which utilizes a device for adjusting wheel braking force to adapt to changes in vehicle or rail surface conditions (the international patent classification number is B0T8 / 00); The invention also relates to a braking system utilizing both brake cylinders and distribution valves, and to an arrangement or configuration of railway vehicle brakes or other retarding devices. It is used to prevent the wheels from locking and sliding due to insufficient adhesion between the wheels and rails when the air brake is used during the operation of the train. Background technique [0002] With the advancement of technology, due to the earlier development of the existing anti-skid device, its function and performance are difficult to meet the needs of high-speed, and it is necessary to redesign more functional and higher-performance anti-skid devices with...
