Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, 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.
A train brake control method according to an embodiment of the present invention is described below with reference to fig. 1, and includes: step 101, receiving fault information of a brake control system sent by the brake control system of a train;
wherein, the train can be a motor train or a subway and the like. The monitoring system in the brake control system can acquire fault information of the brake control system of the Train in real time, and timely upload the acquired fault information to a vehicle-mounted ATP (Automatic Train Protection) system through communication with the vehicle-mounted ATP system of the Train.
102, acquiring the type of fault information according to the fault information of the brake control system; wherein the fault information is pre-associated with the category of the fault information;
the fault information of the brake control system acquired by the vehicle-mounted ATP system may be one or more, and the embodiment is not limited to the number of the fault information. The category of the fault information can be divided and preset according to the influence degree of the fault information on the brake control system of the train. The category of the fault information may also be divided according to the type of fault of the brake control system of the train. The present embodiment is not limited to the method of classifying the category of the failure information.
After the vehicle-mounted ATP system acquires the fault information of the brake control system, matching any fault information with the fault information stored in advance, and taking the category to which the matched fault information belongs as the category of the fault information. And if a plurality of fault information are acquired by the vehicle-mounted ATP system, acquiring the corresponding category of each fault information. Wherein the plurality of fault information may correspond to one category or a plurality of categories. If there are a plurality of pieces of failure information acquired by the on-board ATP system and the plurality of pieces of failure information correspond to a plurality of categories, the category to which the piece of failure information having the greatest influence on the brake control system of the train belongs is set as the category of the plurality of pieces of failure information.
103, acquiring a braking strategy corresponding to the type of the fault information according to the type of the fault information, and adjusting the braking force of the braking control system for braking control of the train according to the braking strategy; wherein the category is pre-associated with the braking strategy;
the braking force of the brake control system for controlling the braking of the train is the braking force of the brake control system for controlling the braking of the train in a normal state. And determining the braking strategy which needs to be adopted by the braking control system for the train according to the type of the fault information of the braking control system. The types of fault information of the brake control systems are different, and the corresponding brake strategies are also different.
The performance of the brake control system is degraded due to a failure of the brake control system of the train. If the brake control system controls the train according to the braking force for controlling the train in a normal state, the requirement for controlling the train brake is difficult to meet, and the safety operation of the train is easily seriously influenced. If the train stops, the performance of the brake control system is reduced, so that the brake force is seriously insufficient, and the stop position of the train is inaccurate. Therefore, before issuing the braking force to the brake control system, the vehicle-mounted ATP system needs to adjust the braking force according to the brake strategy corresponding to the type of the failure information.
And 104, issuing the adjusted braking force to the braking control system so that the braking control system can brake and control the train according to the adjusted braking force.
Specifically, after the vehicle-mounted ATP system adjusts the braking force according to the corresponding braking strategy, the vehicle-mounted ATP system communicates with the braking control system to issue the adjusted braking force to the braking control system. And the braking control is carried out on the train according to the obtained adjusted braking force, so that the braking control on the train is more accurate, and the safe operation of the train is realized. Fig. 2 is a schematic structural diagram of train brake control.
In the embodiment, the fault information of the brake control system of the train is acquired in real time, when the fault information is acquired, the type of the fault information is determined, the braking force is adjusted by adopting a corresponding braking strategy according to the type of the fault information, and the adjusted braking force is issued to the brake control system, so that the brake control system performs real-time brake control on the train according to the adjusted braking force, the performance of the brake control system is fully considered, the brake control system performs more accurate brake control on the train, and the running safety of the train is improved.
On the basis of the above embodiment, the categories in this embodiment include a first category, a second category, and a third category; the first category of fault information includes a communication fault of the brake control system and a bogie fault; the second category of fault information comprises that BSR (pressure transmitter) pressure of the brake control system is smaller than a first preset threshold value and brake air supply pressure of a bogie is smaller than a second preset threshold value; the third type of fault information includes that the value of a sensor of the brake control system exceeds a preset maximum value, the speed sensor has a fault, a brake command and a traction command are issued simultaneously, the brake force issued under control is inconsistent with the brake force actually issued, an ED (Electro Dynamic, electric brake) brake weakening signal is provided when the speed is greater than a third preset threshold value, and the ED brake weakening signal is lost when the speed is less than a fourth preset threshold value.
When the BSR pressure is smaller than the first preset threshold, the brake force is insufficient, and the requirement for train brake control is difficult to meet.
The categories of fault information may be divided into three categories. Different types of fault information indicate different degrees of influence on the brake control system. If the fault information of the brake control system is one or more of the first category of fault information, the brake control system is in serious fault. The brake control system has failed to meet acceptable minimum performance standards and these faults have resulted in the brake control system being unable to modify its function.
If the failure information of the brake control system is one or more of the second type of failure information, it indicates that the brake control system is damaged and the braking performance is degraded. And causes the brake control system to automatically modify its function to provide the most degraded operating performance possible. But the automatic control system still meets acceptable performance standards and can perform a certain braking response.
If the fault information of the brake control system is one or more of the fault information in the third category, the fault information indicates that the brake control system has a slight fault and is fully operable without affecting the performance of the brake control system. Some preventative or corrective maintenance may be required to restore the brake control system to a normal condition.
On the basis of the foregoing embodiment, in this embodiment, the obtaining, according to the type of the fault information, a braking strategy corresponding to the type of the fault information, and adjusting, according to the braking strategy, a braking force of the brake control system for performing brake control on a train includes: if the type of the fault information is the first type, adjusting the braking force of the brake control system for controlling the braking of the train to the maximum braking force of the train; if the type of the fault information is the second type, increasing the braking force of the brake control system for performing brake control on the train; and if the type of the fault information is the third type, the braking force of the brake control system for controlling the train to brake is kept unchanged.
Specifically, after the braking strategy corresponding to the type of the fault information is acquired, the vehicle-mounted ATP system may issue different braking forces to the braking control systems with different fault degrees according to the braking strategy. If the type of the fault information of the brake control system is the first type, the fault occurring in the brake control system is a serious fault. The vehicle-mounted ATP system can send a feedback signal of a primary fault to remind a brake control system of serious faults. And the vehicle-mounted ATP system transmits the maximum braking force of the train to the brake control system when receiving any brake command. And the brake control system performs brake control on the train according to the maximum braking force. The braking instruction is issued by an operator according to the condition that the braking control system is in a normal state.
If the type of the failure information of the brake control system is the second type, the performance of the brake control system is degraded. The vehicle-mounted ATP system can send a feedback signal of a secondary fault to remind the performance reduction of the brake control system. If the brake control system brakes the train according to the braking force for controlling the train in a normal state, the corresponding brake control effect cannot be achieved, and the braking force needs to be increased so as to accurately control the train. The vehicle-mounted ATP system may weight the braking force in the normal state and the maximum braking force of the train to increase the braking force, or may add the braking force in the normal state to a preset safety threshold to increase the braking force.
If the type of the fault information of the brake control system is the third type, the brake control system can respond normally, and the performance of the brake control system is not affected. However, in order to prevent the failure deterioration of the brake control system, the vehicle-mounted ATP system may send a feedback signal of the three-level failure to alert the need for maintenance of the brake control system. The brake control system keeps the brake force for controlling the train to brake in a normal state unchanged, and performs brake control on the train. Fig. 3 is a schematic structural diagram illustrating the classification of fault information and the corresponding braking strategy of the brake control system.
According to the method, the braking strategy corresponding to the fault information type is obtained according to the fault information type of the braking control system, and the braking force actually required by the braking control system for braking control of the train is adjusted according to the corresponding braking strategy. The train braking control method enables the braking force obtained by the braking control system to be more reasonable and the braking control of the train to be more accurate.
On the basis of the above embodiments, the present embodiment includes: multiplying the braking force of the brake control system for braking the train by a preset multiple; wherein the preset multiple is greater than 1.
Specifically, if the type of the fault information of the brake control system is the second type, the performance of the brake control system is reduced, the braking force for braking the train is insufficient, the braking force in the normal state can be multiplied by the preset multiple to adjust the braking force, and the adjusted braking force is issued to the brake control system, so that the running safety of the train is ensured. The preset multiple can be adjusted according to actual conditions. For example, the preset multiple may be any value between 1.5 and 2.
