Abstract
The invention relates to a TCMS control-based anti-skid control method for an all-axle tramcar, which is provided with two bogies, wherein 2 axles of each bogie are driven by a motor, when a TCMS system detects that 4 axles slide simultaneously, the electric brake of 1 axle in the 4 axles is cut off, so that the axle with the electric brake cut off has no electric brake force or hydraulic brake force, and the TCMS system sends the speed of the axle with the electric brake cut off as the current actual speed of a train to an electric brake system as the reference speed of the train for train sliding protection. When the train slides, the TCMS system fixedly cuts off the electric brake system with a moving shaft, and the electric brake system loses brake force and becomes an unpowered trailing shaft, so that the TCMS system can find the reference train speed and inform the electric brake system to carry out effective anti-skid control, and can effectively avoid wheel wiping or other faults which influence the train running safety and are caused by the fact that the train does not have the reference train speed when the train slides seriously.
Description
Technical Field
The invention relates to an anti-skid control method applied to a full-moving axle tramcar without a radar and a dragging bogie.
Background
At present, the urban rail transit system develops rapidly, various novel rail transit vehicles are applied to different cities, including subway vehicles, air rail vehicles, trams and the like, wherein the trams are the most rapid type of vehicles which are developed at home and applied to more cities recently, most of the trams have only two or three bogies due to the fact that most of the trams are short in design length, the three bogie vehicles are configured into two unpowered bogies with two powered bogies, and only two bogie type vehicles are all configured into powered bogies and most of the two powered bogies are in shaft control driving, namely, the shafts of all the bogies are driven by motors. When a train is dragged, each axle provides traction power, and when the train is braked, the motor on each axle is preferentially used for braking, if the electric brake system performs sliding protection when the train is braked, the judgment of sliding is carried out according to methods such as deceleration and speed difference, the judgment methods relate to a reference speed of the train, and when the full-axle tramcar without radar or GPS speed measurement performs serious sliding, the electric brake system performs sliding protection according to overlarge acceleration of the axle, but the electric brake system does not have the reference speed of the train during the sliding protection, applies a force value to wheels according to the set deceleration to reduce the axle speed, and then considers that the train is stopped, but the actual train speed is in a high-speed running state, this is likely to cause the operation safety of the train to be affected by the wheel-wiping or other faults.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects in the prior art and provide a tramcar all-moving axle anti-skid control method based on TCMS control, which can effectively avoid the phenomenon that a train does not have a train reference speed when the train slides seriously, so that the train is wiped or other faults affecting the running safety of the train are avoided.
In order to solve the technical problems, the invention provides a method for controlling anti-skid of a whole moving axle of a tramcar based on TCMS control, wherein the tramcar is provided with two bogies, and 2 axles of each bogie are driven by a motor, and the method is characterized in that: when the TCMS detects that 4 shafts slide simultaneously and the duration time T is reached, the electric brake of 1 shaft in the 4 shafts is cut off, so that the shaft with the electric brake cut off has neither electric brake force nor hydraulic brake force, and after the electric brake of 1 shaft is cut off, the TCMS sends the speed of the shaft with the electric brake cut off as the current actual speed of the train to the electric brake system as the train reference speed for train sliding protection.
The invention also has the following further features:
1. after cutting off the electric brake of 1 axle, the TCMS system controls to apply the magnetic track brake to achieve the safe brake stopping distance of the train.
2. And when the TCMS system detects a train inertia command, the TCMS system recovers the cut electric brake and stops applying the magnetic track brake, and the train inertia command is sent by a driver.
3. When the train speed is lower than M, the electric braking force fades out, and the hydraulic system applies the holding brake.
4. The value range of T is 0-500 ms.
5. The value range of M is 5-7 KM/H.
When a Train slides, a sliding signal is reported to a Train Control and Monitoring System (TCMS) by the shaft Control electric braking System, and when the TCMS judges that all moving shafts slide under the Control of the electric braking System, the TCMS fixedly cuts off the electric braking System of one moving shaft, so that the electric braking System loses braking force and becomes an unpowered trailing shaft, and thus the TCMS can find a reference Train speed and inform the electric braking System of effective anti-skid Control, and can effectively avoid the phenomenon that the Train does not have a wheel wiping or other faults which influence the Train running safety caused by the reference Train speed when the Train slides seriously.
Drawings
The invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic view of a full-moving shaft of a tramcar.
Detailed Description
As shown in fig. 1, a schematic view of a fully-motorized axle of a tram having two bogies, 2 axles of each bogie being driven by a motor. When the vehicle runs normally, the vehicle is braked by the electric brake, and when the vehicle speed is lower than 5KM/H, the electric brake force fades out, and the hydraulic system applies the holding brake.
The anti-skid control method for the whole moving axle of the tramcar based on TCMS control in the embodiment comprises the following steps:
when the TCMS detects that the 4 shafts slide simultaneously (in order to prevent no movement, a duration T can be set, and the value range of T is 0-500 ms), the TCMS judges that the train has no reference speed, and cuts off the electric brake of 1 shaft in the 4 shafts (the shaft at the leftmost side in the figure) so that the shaft with the cut electric brake has no electric brake force or hydraulic brake force, the shaft is the trailing shaft, and the speed of the shaft can be considered as the actual speed of the train. After the electric brake of 1 shaft is cut off, the TCMS system sends the speed of the shaft with the cut-off electric brake as the current actual speed of the train to the electric brake system as the train reference speed for train sliding protection, and meanwhile, the TCMS system controls the application of magnetic track brake to achieve the safe brake stopping distance of the train.
When the TCMS system detects a train inertia command, the TCMS system recovers the cut electric brake and stops applying the magnetic track brake, and the train inertia command is sent out by a driver operating handle.
By implementing the method, the problem of wheel scratch caused by the fact that the actual speed of the train is not used as a reference when the full-moving-axle tramcar slides seriously (such as an antiskid test) can be effectively avoided.
Based on the implementation method, similar expansion can be sequentially carried out under different normal working conditions of the electric brake system, and the scheme needs to protect the cut-off electric brake system of the full-moving-axle tramcar and select the axle speed of the cut-off electric brake system as the standard speed of the train for anti-skid protection.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
