Brake curve switching control method and railway vehicle

Abstract

The embodiment of the invention provides a braking curve switching control method and a rail vehicle, the method is used for controlling the rail vehicle to switch braking curves when the rail vehicle passes through different lines, the different lines have different highest operation speed limits, and the vehicle is preset with corresponding braking curves according to the different highest operation speed limits; comprising the following steps that a vehicle receives information of a ground signal mark through vehicle-mounted signal equipment; the ground signal mark is arranged between the A line and the B line which are communicated; the vehicle-mounted signal equipment transmits the information to a vehicle control system; and the vehicle control system judges the running state of the vehicle according to the information, and instructs a braking system of the railway vehicle to act and switch a braking curve according to a judgment result. When the vehicle passes through the ground signal marks of the different lines, the braking curves of the corresponding lines are switched, interconnection and interworking operation of the different lines are achieved, passengers do not need to carry out additional transfer, the travel time is saved, the line transport capacity is improved, and the line and vehicle transformation cost is low.

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular to a braking curve switching control method and a rail vehicle. Background technique [0002] With the rapid expansion of the city, a large number of people are pouring into the city, and the existing urban rail scale cannot meet the growth of the floating population. We can only improve the operating capacity of the existing lines and build new lines to meet the transportation capacity. The new lines need to be seamlessly integrated with the existing lines in order to make it more convenient for people to ride and improve operational efficiency. [0003] For new lines, the corresponding standards will be higher with the improvement of technology, such as higher line operating speed. Also for vehicles, the speed of vehicles on new lines may be higher than that of existing lines, and the operating speeds and deceleration curves of new and old vehicles will be differe...

AI Technical Summary

Problems solved by technology

If vehicles are allowed to operate on different routes, and the signal system still adopts the original vehicle control strategy, the original vehicle control strategy will not match the characteristics of the vehicle, which will seriously affect the safety of operation, and the capacity of the line cannot be fully utilized.

[0006] In order to realize the interconnection of new and old lines and vehicles, at least the signal system and vehicle signals need to be transformed, whether it is to upgrade the existing line signal system and vehicle performance, or to use the original signal system for new lines, and to reduce vehicle traffic. Performance parameters, for users, will cause great waste of cost

[0007] And reduce the performance parameters of new vehicles to match the ability of existing lines. The result is that the performance of vehicles is not fully utilized, resulting in waste of operating costs.
