Independent control braking system used for tramcar early warning avoidance

Abstract

The invention relates to an independent control braking system for tram pre-warning avoidance, comprising a tram pre-warning avoidance module and a permanent magnet eddy current brake used for tram deceleration and braking controlled by the tram pre-warning avoidance module, the permanent magnet eddy current brake includes The rotor assembly, the stator assembly and the drive assembly, the stator assembly includes two pole piece stator disks and a permanent magnet stator disk, a plurality of pole pieces are evenly distributed along the circumference of the pole piece stator disk, and a plurality of pole pieces are evenly distributed along the circumference of the permanent magnet stator disk A pair of permanent magnets with NS poles arranged in the axial direction, each permanent magnet pair consists of two permanent magnet monomers with NS poles facing the same direction, the NS poles of adjacent permanent magnet pairs are facing opposite, and the drive assembly is connected to the permanent magnet stator plate . Compared with the prior art, the present invention assists the early warning and avoidance of the tram by setting the permanent magnet eddy current brake, which can realize a more frequent deceleration mechanism, is simple to control and responsive, greatly reduces the friction loss of the tram, and greatly improves the The operating efficiency of the tram.

Description

technical field [0001] The invention relates to the field of tram operation control, in particular to an independently controlled braking system for tram pre-warning and avoidance. Background technique [0002] The existing vehicle braking system can meet the requirements as the driver's normal speed regulation or parking, as well as braking in emergency situations. However, according to the operation requirements of trams, they share the right of way with social vehicles and pedestrians. Judging from the operation of trams in areas that have been opened, collisions with other vehicles at crossings or crowded areas have become a prominent problem, which affects the tramway. An important factor in the running quality of trams, which was one of the main problems of historically troubled trams. [0003] Under normal conditions, trams generally use manual driving. At this time, the safety of train operation mainly depends on the driver’s manual observation and responsibility fo...

AI Technical Summary

Problems solved by technology

[0003] Under normal conditions, trams generally use manual driving. At this time, the safety of train operation mainly depends on the driver’s manual observation and responsibility for performing duties. This operating condition has certain potential safety hazards. In order to reduce the impact of accidents on the vehicles The impact of normal operation needs to be eliminated by more practical and effective means

[0004] For complex road conditions, it is still difficult to realize automatic deceleration and avoidance, such as in heavy smog, rain and snow, and poor lighting at night

Simply relying on the driver to observe the surrounding situation cannot guarantee safety. It is necessary to use the sensor test system to monitor, evaluate and warn the surrounding moving objects and pedestrians, and further directly control the deceleration device or control the vehicle braking system to improve the safety of the tram

[0005] The existing related invention patents are mainly used in the field of rail transit with independent road rights such as urban subways. They are mainly aimed at the anti-collision targets of front and rear vehicles. Realize the alarm in the driver's control room, still rely on the role of the driver to ensure the safety of the vehicle, and fail to directly control the auxiliary braking device for braking by the judgment signal
