Obviously, the drawings in the following description are only some embodiments of the application, and other drawings can be obtained by those skilled in the art without creative labor.

[0027] The technical solutions in the embodiments of the application will be described clearly and completely in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the application.
[0028] The core of the application is to provide a brake abnormal application monitoring control system.
[0029] In order for those skilled in the art to better understand the scheme of the present application, the present application is further described in detail below in combination with the drawings and specific embodiments.
[0030] When the train is running on the main line, the passenger dispatching density is large and the time interval is short. Once the train fails to block the line, it will most likely cause a large area of subsequent vehicle delay, which will bring great inconvenience to passenger travel and operation management of various railway bureaus. In order to ensure the safety of high-speed train operation, the reliability of the braking system of the train becomes particularly important. The braking system is the safety guarantee for high-speed train operation, and a good control strategy needs to be designed to ensure safe parking. At present, the abnormal braking application function of the motor train unit adopts a through hard-wire design. The hard-wire through structure results in a long cable length. When a single point fails, the whole isolation measure is usually adopted, which cannot realize precise isolation. If functional modification is needed, line modification needs to be made on the basis of the original circuit. Such modification may involve the abandonment and re-manufacture of the circuit board or the change of external wiring, and all circuit boards are at risk of burning. The protection to avoid burning is all concentrated on the side of the air switch. If a problem occurs, the air switch will be tripped, which will result in a large area of logic control circuit failure. If the current technology is used to protect each circuit, the cost will be too high. The pure communication design cannot guarantee the communication quality and reliability.
[0031] At present, the braking valves and air valves required by the vehicle need to be manually cut off. Some valves are under the vehicle or in the power distribution cabinet, which causes inconvenience in operation and problems such as working conditions not allowed. The intelligent remote control device can realize remote cutting and recovery instructions, reducing the manual operation link.
[0032] At the same time, the vehicle has four braking abnormal application monitoring, i.e. parking brake abnormal application, holding brake abnormal application, service brake abnormal application and emergency brake abnormal application, which are independent of each other, and are not convenient for intelligent and integrated control of the vehicle.
[0033] To solve the above problems, the embodiment provides a braking abnormal application monitoring control system, as shown in Figure 1 The braking abnormal application monitoring control system comprises:
[0034] a pressure collecting device 11, a vehicle braking execution unit 12, a vehicle control module 13, a remote control module 14 and an execution terminal 15.
[0035] The pressure collecting device 11 is connected with the vehicle braking execution unit 12 and the vehicle control module 13, the vehicle braking execution unit 12 is connected with the vehicle control module 13, the vehicle control module 13 is connected with the remote control module 14, and the remote control module 14 is connected with the execution terminal 15.
[0036] The pressure collection device 11 collects the pressure signal of the brake system, the vehicle brake execution unit 12 controls the vehicle brake, the vehicle control module 13 obtains the pressure signal output by the pressure collection device 11 and the brake signal output by the vehicle brake execution unit 12, and controls the execution terminal 15 through the control remote control module 14 to realize corresponding train brake processing.
[0037] It should be noted that the embodiment is applied to a train set of multiple trains, and if applied to a train set, a brake abnormal application monitoring control system is separately arranged for each train, that is, each train compartment is provided with a pressure collection device 11, a vehicle brake execution unit 12, a vehicle control module 13, a remote control module 14, and an execution terminal 15.
[0038] The pressure collection device 11 mentioned in the embodiment collects the pressure signal of the brake system and analyzes the pressure signal, that is, the air pressure generated by the actual brake system of the current train is collected, and if the pressure signal is detected, it means that the current train is taking brake measures, for example, the current air pressure change is identified through a gas pressure sensor. The embodiment does not limit what kind of brake, parking brake abnormal application, holding brake abnormal application, normal brake abnormal application, and emergency brake abnormal application, the pressure collection device 11 can analyze the specific brake type according to the collected pressure signal, and send the brake state and brake type to the vehicle control module 13.
[0039] The vehicle brake execution unit 12 mentioned in the embodiment refers to outputting a brake application signal to control the vehicle brake, and the vehicle brake execution unit 12 is connected with the vehicle control module 13. The vehicle control module 13 receives the brake signal output by the vehicle brake execution unit 12, which means that the vehicle brake execution unit 12 controls the vehicle brake at this time.
[0040] The vehicle control module 13 mentioned in the embodiment is the total control module of the train, and in the embodiment, the monitoring and control of the train brake are mainly realized. The type of the vehicle control module 13 is not limited in the embodiment, which can be an artificial intelligence processor, a central processing unit, etc.; and it can be designed according to actual needs.
[0041] The remote control module 14 mentioned in the embodiment is used for receiving the control signal output by the vehicle control module 13, and controlling the execution terminal 15 according to the control signal. The execution terminal 15 mentioned in the embodiment includes but is not limited to brake valves, air valves, contactors, etc.
[0042] The vehicle control module 13 receives the brake signals output by the pressure acquisition device 11 and the vehicle brake execution unit 12, i.e. the brake system air pressure signal output by the pressure acquisition device 11 and the brake control signal output by the vehicle brake execution unit 12. Preferably, a soft logic controller is built in the vehicle control module 13 to realize soft logic control, and different functions of the system are controlled by logical operations such as "or", "and", and "not". For example, if the brake system air pressure signal output by the pressure acquisition device 11 is not received, but the brake control signal output by the vehicle brake execution unit 12 is received, it indicates that the train brake is abnormal at this time, and emergency braking needs to be taken.
[0043] The vehicle control module 13 controls the execution terminal 15 by controlling the remote control module 14 according to the obtained brake signals output by the pressure acquisition device 11 and the vehicle brake execution unit 12, to realize corresponding train braking processing. For example, when brake abnormality is detected, the vehicle traction can be selected to be cut off, and full train braking can be applied to slow down the speed if necessary. If a brake function needs to be cut off, the remote control module 14 is controlled to remotely cut off the valve of the related execution terminal 15, and a shielding signal of the related function is sent to the vehicle brake execution unit 12. When a signal channel (or board card) is overcurrent, the vehicle control module 13 will cut off the channel (or board card) by controlling the remote control module 14.

The pressure acquisition device 11 acquires the pressure signal of the brake system, the vehicle brake execution unit 12 controls the vehicle brake, the vehicle control module 13 obtains the pressure signal output by the pressure acquisition device 11 and the brake signal output by the vehicle brake execution unit 12, and controls the execution terminal 15 by controlling the remote control module 14 to realize corresponding train braking processing. The vehicle control module 13 receives the brake signals output by the pressure acquisition device 11 and the vehicle brake execution unit 12, i.e. the brake system air pressure signal output by the pressure acquisition device 11 and the brake control signal output by the vehicle brake execution unit 12, controls the execution terminal 15 by controlling the remote control module 14 to realize corresponding train braking processing, realizes single-point fault single-point isolation and single-car fault single-car isolation function through the vehicle control module 13, and the brake function of other cars is not affected after isolation.

[0048] According to the above embodiment, in some abnormal braking cases, not only the traction of the vehicle needs to be cut off, but also the brake of the whole train needs to be applied to slow down the speed when necessary.
