Anti-backward-slip control system for railway vehicle, and method thereof

Abstract

The invention discloses an anti-backward-slip control system for a railway vehicle, and a method thereof. The method comprises the following steps: an analog signal processing unit converts an input speed signal into a level signal which can be received by a speed signal processing unit; the speed signal processing unit judges a practical steering direction of a motor according to the speed signal, transmits the steering direction to an embedded processing unit, and outputs the processed speed signal to a digital signal processing unit; the embedded processing unit judges a vehicle slip signal according to a practical steering signal of the motor and a current driver steering handle state signal of a driver console, and transmits the vehicle slip signal to the digital signal processing unit; after receiving the vehicle slip signal, the digital signal processing unit calculates whether a vehicle slip distance exceeds a threshold value; and if so, the digital signal processing unit transmits a signal indicating that the vehicle slip distance exceeds the threshold value, to the embedded processing unit, the embedded processing unit triggers and transmits an anti-slip activation signal to a railway vehicle network control system to control a braking system to brake and stop the vehicle emergently. Due to the adoption of the anti-backward-slip control system and the method, the problem of backward slip of the railway vehicle can be solved effectively.

Description

technical field [0001] The invention relates to a rail vehicle control system and a method thereof, in particular to an anti-rollback control system and a method thereof applied to rail vehicles, especially electric transmission subway engineering maintenance vehicles. Background technique [0002] Rail vehicles generally include various types of rail operating vehicles and rail engineering vehicles, and are widely used in railways, light rails, urban rails, and subway transportation and engineering fields. Taking the subway engineering maintenance vehicle as an example, the subway engineering maintenance vehicle is an important traction unit in various maintenance and construction operations of the subway. With the continuous progress of rail transit technology, the electric drive subway engineering maintenance vehicle has also been widely used as a new model. However, when the electric transmission subway engineering maintenance vehicle participates in the material transp...

AI Technical Summary

Problems solved by technology

[0010] (1) The purchase amount of existing anti-slip equipment is large. For example, there are often dozens of subway engineering maintenance vehicles in a subway depot in a city, and it often requires a lot of money to purchase corresponding iron shoes and mechanical anti-slip equipment for each vehicle;

[0011] (2) The overall structure of the existing mechanical anti-slip equipment is complex, and the installation cycle is long. Due to the large size of the mechanical anti-slip equipment itself and the need for some auxiliary equipment after installation, such as anti-slip fixed sleepers, etc., the mechanical The installation period of the anti-slip equipment itself will be relatively long;

[0012] (3) When the existing mechanical equipment and iron shoes prevent the vehicle from slipping, the actual operation of the personnel is labor-intensive and the operation mode is backward; the anti-slip equipment is generally composed of metal components, which are large in size and heavy in quality, requiring manual operation by personnel, and It takes a long time to recover from the aftermath, and it is easy to cause the operator to be overworked; due to the complicated anti-slip operation of the mechanical equipment, it often leads to improper operation of the personnel, resulting in a slipping accident, so the operation mode is also backward;

[0013] (4) The existing anti-slip control system does not have the function of judging the actual steering of the motor;

[0014] (5) The existing anti-slip control system does not have the function of calculating the vehicle slip distance
