Train automatic control method, device and vehicle-mounted equipment for severe weather

Abstract

The invention provides an automatic train control method, a device, on-board equipment and an electronic device for dealing with bad weather. The method comprises the following steps: a train determines a train control mode corresponding to a current state according to its own idle slip state; Among them, the train control mode includes more than two kinds of control mode, each kind of control mode corresponds to a kind of idle skid condition; The train automatically adopts the corresponding control strategy to automatically control the train according to the determined control mode. As willbe seen, in that present invention, the train can automatically enter the corresponding control mode according to its idling and skidding condition, Automatic train control in inclement weather can berealized without the participation of central dispatchers. Trains can automatically cope with inclement weather, and can provide a variety of control measures to achieve fine control in inclement weather and improve the safety of driving in inclement weather.

Description

technical field [0001] The invention relates to the technical field of track control, in particular to an automatic train control method, device, vehicle-mounted equipment and electronic equipment for severe weather. Background technique [0002] The impact of severe weather (such as rain and snow) on train operation cannot be underestimated, and severe weather seriously affects the safety of train operation. However, at present, some trains do not have corresponding processing strategies for rainy and snowy weather, while other trains have added processing strategies for rainy and snowy weather, but manual intervention is required, and the processing method is fixed and cannot be flexibly adjusted according to the actual situation of the line. [0003] For example, for the current high-speed rail train control system (CTCS3+ATO), the high-speed rail environment is complex, the lines are in an open environment, and there are a large number of ground lines. The adhesion coef...

Problems solved by technology

[0006] (1) The high-speed rail automatic driving equipment currently has no treatment for rainy and snowy weather. When rainy and snowy weather occurs, if no corresponding control strategy is adopted, the parking accuracy will decrease, and the station will even exceed the standard, threatening driving safety.

[0007] (2) The urban rail train control system must manually intervene in the processing of rainy and snowy weather, and the processing method is fixed, and cannot be flexibly adjusted according to the actual situation of the line; a fixed maximum train traction and braking rate is used to limit, while the maximum train traction and braking rate The braking rate changes with the speed. This method of fixed value limitation may cause no effect or greatly reduce operating efficiency
