Problems solved by technology

However, when the speed limit section is more complex, there will be continuous speed limit situations, or in order to improve driving efficiency, short speed limit sections are embedded in long speed limit sections, etc.
[0004] In these nesting situations, if the driver is asked to use manual judgment, it is easy to appear unclear levels of judgment, control confusion, etc., which endangers driving safety; Passing at the lowest speed due to the speed limit of the section, it will lose speed and cause the train to fail to reach the destination within the stipulated time

Embodiment Construction

[0067] The speed limit information nested processing method of the present invention, such as figure 1 As shown, it mainly includes the following three steps:

[0068] Step a: State initialization, start to receive speed limit information;

[0069] Step b: process the speed limit information, determine its type and the number of floors, so as to determine the current state of each speed limit information;

[0070] Step c: Determine the next running state of the train according to the current state of the speed limit information and the running state of the train, output prompt information to the display of the automatic control device, remind the driver of the current condition of the train, and output unloading, normal braking or emergency braking at the same time The control signals such as actuation and so on are sent to the corresponding control valves on the train to reduce the train speed to a limited speed to ensure driving safety. After execution, jump back to step ...

Abstract

The invention discloses a nesting processing method of the continuous speed-limiting messages of trains, which concretely comprises the following steps of: initializing states and starting to receive speed-limiting messages; judging the states of the speed-limiting messages; and contrasting the current states of trains to output corresponding control. In the invention, continuous speed-limiting nested messages are processed by adopting an event-triggered state transition method, and the conversion among the four states is triggered by a T-mark event and a speed reduction-mark event; the invention has the advantages of high operating efficiency, high flexibility, strong expandability and the like and still can clearly judge the states of the speed-limiting messages under the condition of unknown number of layers; the control and the judgement on the running states of the trains are clear, and the conditions are definite, thereby avoiding the phenomena of unclear layer judgement, disordered control and the like caused by artificial reasons and assisting the drivers of the trains to pass speed-limiting sections at the optimal speed under the condition of ensuring the driving safety of the trains.

Description

technical field [0001] The invention relates to a nested processing method for train continuous speed limit information, in particular to a nested processing method for train continuous speed limit information based on event-triggered state transition. Background technique [0002] At present, the speed limit of trains on my country's railways generally adopts two methods, one is the inherent speed limit of bridges, curves and other road sections, and the other is the temporary limit when natural disasters and other emergencies or temporary constructions occur along the railway. speed. With the development of technology, the inherent speed limit can realize automatic speed limit by pre-setting the train traffic monitoring device (LKJ). For the temporary speed limit, the traditional method is to place a temporary signboard or use a walkie-talkie to inform the driver. The speed information is automatically processed, which eliminates the influence of human factors and greatly...
