Detailed Description
The core of the invention is to provide a train brake control method and related components, each carriage needs to apply brake force, and all electric brakes are not needed to be applied by each motor train, so that the single-shaft brake of the motor trains is reduced, and the sliding of the motor trains is reduced.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a train braking control method provided by the present invention, including:
s11: after a proportional braking instruction sent by a driver is received, calculating the total braking force required by the train based on the speed and the weight of the current train;
the applicant considers that when a train in the prior art brakes, in order to avoid the brake pad loss, the electric brake is usually applied only by each train in the train to brake the train. However, since there are not only railcars but also trailers in a train, and the trailers can apply only air brakes, if electric brakes are applied to the train by only the railcars, the railcars may slide when the adhesion of the wheel rails is unfavorable in rainy and snowy weather. For example, 8 marshalling 4-motor-4-trailer train groups are provided with 4 motor vehicles and 4 trailers, in the prior art, 4 motor vehicles apply electric braking force, the whole train has no air braking force supplement, the whole train has several kinds of 4 motor vehicles, the 4 motor vehicles, especially the first motor vehicle, are easy to slide due to the fact that the single-shaft braking force of the motor vehicles is too large, if the sliding control is not proper, wheels are locked, and the risk of wheel rubbing exists.
In order to solve the technical problem, the proportional braking mode is set, when a driver-side proportional braking instruction is given, the proportional braking mode is entered, and the electric braking is not only provided by the motor train, but the total braking force required by the train is calculated according to the speed and the weight of the train.
In the present application, when receiving a proportional brake command sent by a driver, the driver may receive the proportional brake command when pressing a proportional brake button, but the present application is not limited thereto, and a control panel may be provided, and the user may select proportional braking through the control panel to send the proportional brake command.
It should be noted that, when calculating the total braking force required by the train, the total braking force may be calculated not only from the speed and weight of the train but also from the speed after braking, and the present application does not limit this.
S12: distributing the total braking force to each carriage based on the total braking force and the weight of each carriage, wherein the braking force distributed to each carriage is in direct proportion to the weight of each carriage, and the deceleration of each carriage is the same when braking;
in the embodiment, after the total braking force is calculated, the total braking force is distributed to each compartment according to the weight of each compartment, and the braking force distributed to each compartment is in direct proportion to the weight of each compartment so as to ensure that the deceleration of each compartment is the same.
S13: when the compartment is a motor car and the braking force distributed to the motor car is smaller than the maximum electric braking force of the motor car, controlling the motor car to apply an electric braking force equal to the braking force distributed to the motor car;
however, in order to avoid brake pad wear of the motor train, the motor train which can apply the electric brake preferentially applies the electric brake, and if the motor train fails and cannot apply the electric brake, the failed motor train applies the air brake.
Specifically, when the braking force distributed to the motor car is smaller than the maximum electric braking force that the motor car can increase, the motor car may be controlled to apply an electric braking force having the same magnitude as the braking force distributed to the motor car. And if the braking force distributed to the motor train is larger than the maximum electric braking force which can be applied by the motor train, the motor train not only applies the maximum electric braking force, but also applies air braking, so that the finally applied air braking and the maximum electric braking force are the braking force distributed to the motor train.
In the present application, the maximum electric braking force that can be applied by the motor vehicle is a certain proportion, for example, 90%, of the limit electric braking force that can be applied by the motor vehicle.
S14: when the compartment is a trailer and the braking force allocated to the trailer is less than the maximum air braking force of the trailer, the trailer is controlled to apply an air brake equal to the braking force allocated to the trailer.
For the trailer, the trailer can only apply air brake, and if the brake force distributed to the trailer is smaller than the maximum air brake force of the trailer, the trailer can distribute the air brake force to the trailer.
If the braking force distributed to the trailer is larger than the maximum air braking force of the trailer, the braking force larger than the maximum air braking force is distributed according to the weight of each carriage, so that the normal operation of the trailer is ensured while the brake is applied.
Referring to fig. 2, fig. 2 is a schematic diagram of a service brake application flow in the prior art, when a proportional brake command is not received, but a driver controls a train to apply service brakes, electric brakes are applied by the motor cars in a brake application manner in the prior art to satisfy a total brake force, if the total electric brake force that can be applied by the motor cars that can normally apply the electric brakes is less than the calculated total brake force, all electric brake forces are applied by the motor cars that can still apply the electric brake forces, the remaining brake forces are distributed to the motor cars that can still apply the electric brake forces, and air brake forces are applied by the motor cars that can apply the electric brake forces to satisfy the total brake force. And thirdly, if the trailer and the failed motor car apply air brake, the total brake force still cannot be met, and then the air brake is applied while the electric brake force is applied by each section of normal motor car so as to meet the total brake force.
In summary, in the embodiment, if a proportional braking instruction is received, the total braking force required by the train is calculated based on the speed and the weight of the train, the total braking force is distributed to each car, and the braking force distributed to each car is positively correlated with the weight of the car, so that the deceleration of each car is the same, and the synchronous deceleration of each car is ensured.
On the basis of the above-described embodiment:
as a preferred embodiment, after receiving a proportional braking instruction sent by a driver, before calculating the total braking force required by the train based on the speed and the weight of the current train, the method further comprises the following steps:
judging whether a service brake application instruction sent by a driver is received;
if yes, the step of calculating the total braking force required by the train based on the speed and the weight of the current train after receiving a proportional braking instruction sent by a driver is carried out;
if not, controlling the train not to apply the braking force.
In the embodiment, the applicant considers that a driver wants to apply service brake under other conditions and does not want to apply proportional brake, before a proportional brake instruction is received, whether the service brake application instruction sent by the driver is received or not is judged, if the service brake application instruction is not received, proportional brake application is not carried out, because the condition is possibly caused by misoperation of the driver, the proportional brake can be applied only when the proportional brake instruction is received after the service brake application instruction is received, otherwise, the service brake is applied, namely electric brake force is preferentially applied by each motor car, and air brake is applied by a trailer and a faulty motor car.
As a preferred embodiment, after receiving a proportional braking instruction sent by a driver, the method further comprises the following steps:
judging whether a service brake application instruction sent by a driver is received within a preset time;
if yes, the step of calculating the total braking force required by the train based on the speed and the weight of the current train is carried out;
if not, controlling the train not to apply the braking force.
In this embodiment, the applicant considers that in the prior art, when a driver controls a braking mode of a train, a proportional braking instruction may be sent first, if a service braking application instruction sent by the driver is received within a preset time, for example, 10S, the proportional braking is applied, and if the service braking instruction is not received within the preset time, the brake is not applied.
As a preferred embodiment, after receiving a proportional braking instruction sent by a driver, before calculating the total braking force required by the train based on the speed and the weight of the current train, the method further comprises the following steps:
and if an emergency brake application instruction sent by a driver is received, calculating the total braking force required by the train based on the speed and the weight of the current train, distributing the total braking force to each carriage based on the total braking force and the weight of each carriage, wherein the braking force distributed to each carriage is in direct proportion to the weight of the carriage, and the deceleration of each carriage during braking is the same.
In addition, if an emergency brake application command sent by a driver is received, proportional braking is directly applied.
It should be noted that the difference between the service braking and the emergency braking is that if the train is controlled to have a preset speed from the initial speed to the speed after braking, and the time required by the service braking is longer than the time required by the emergency braking, the service braking may also be designed as multi-stage braking, and the time of each stage of braking is different, i.e. the braking intensity is different, so that the driver can select the corresponding braking level by the currently required braking force to perform corresponding braking on the train. If the driver sends a service brake application command and then sends a proportional brake command, the train is controlled to brake at the service brake level set by the driver.
As a preferred embodiment, each of the cars includes a brake control unit;

judging whether a feedback signal sent after a brake control unit of each carriage applies a braking force is received;
if yes, the proportional braking indicator lamp is controlled to be turned on.
