Problems solved by technology

[0004] However, in the prior art, when the train performs safety braking due to the power failure of the safety loop, the train will generate a relatively large impact force due to the large braking force, resulting in poor riding comfort and even causing passengers to Falls and other hazards to passenger safety

Abstract

The invention relates to a safety braking method and device and a computer readable storage medium. The method comprises the steps of monitoring the safety state and the running speed of a train; in response to the safety state difference, judging whether the driving speed is greater than a speed threshold value or not; in response to the fact that the running speed is greater than the speed threshold value, rapidly braking the train at a first deceleration, andcontinuously monitoring the running speed; and in response to the fact that the running speed is smaller than or equal to the speed threshold value, stably braking the train at a second deceleration, wherein the first deceleration is larger than the second deceleration. According to the invention, the impact force of the vehicle can be reduced while safe operation of the vehicle is considered, so that the riding comfort of passengers is improved.

Description

technical field [0001] The invention relates to a train safety braking technology, in particular to a train safety braking method and a train safety braking device. Background technique [0002] Multi-group articulated trains can adopt exclusive right of way or mixed right of way according to urban road planning and design. As a kind of road traffic, in order to improve the operating efficiency, the operating speed of multi-group articulated trains is relatively high. At the same time, in order to take safety into account, multi-group articulated trains have more braking redundancy and have multiple braking modes. [0003] As a redundant guarantee measure for vehicle safety, safe braking has the characteristics of large braking deceleration and is used to meet the operating characteristics of road vehicles. As a braking mode of multi-group articulated trains, safety braking is mainly used to brake the train in time when the train system fails, so as to ensure the safety of...
