DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them.

In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

[0023] In order to facilitate a clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and order of execution.

[0024] The embodiments of the present application describe some exemplary embodiments for the purpose of explanation. It should be understood that the present application can be implemented in other ways that are not specifically shown in the drawings.

[0025] like Figure 1 As shown, the embodiment of the present application provides a train rear-end collision prevention method, which can be applied to a train rear-end collision prevention device. The train rear-end collision prevention method may include S101-S103: S101. A train rear-end collision prevention device obtains braking parameter information of a front adjacent train.

[0026] The above braking parameter information is used to indicate the corresponding parameter information of the train during the braking process. The braking parameter information includes one or more of the following: brake pedal displacement, brake cylinder pressure, brake pedal stepping speed, train speed information before and after the brake pedal is stepped on, operating parameter information of each component in the braking system, and overall output torque information of the braking system.

[0027] Optionally, the train rear-end collision prevention device can receive the braking parameter information sent by the adjacent train in front, and the braking parameter information is information collected by a sensor device of the adjacent train in front, and the sensor device includes at least one of the following: an on-board automatic train protection system (Automatic Train Protection, ATP) and sensors installed on the inner side of the wheels at the front and rear ends of the train.

[0028] It should be noted that since the sensors installed on the inner side of the wheels at the front and rear ends of the train are small on-board devices, the equipment installed on a single vehicle is simple and small in number, and there is no need to lay other additional equipment on the trackside. Therefore, there is no need for excessive cost expenditure for new additions or upgrades.

[0029] Optionally, the braking parameter information is parameter information sent when the braking state of the adjacent train in front is abnormal.

[0030] Optionally, the adjacent train in front can obtain the actual braking torque of the train through a sensor device when braking through the automatic emergency braking system; and when the actual braking torque is less than the standard braking torque, it is determined that the braking state is in an abnormal state.

[0031] Specifically, Figure 2 As shown, the information control device of the front adjacent train can receive the braking parameter information sent by the sensor and the on-board ATP at the same time. When the braking parameter information sent by either the sensor or the on-board ATP is abnormal, the information control device of the front adjacent train can immediately transmit the abnormal braking parameter information to the information control device of the rear train by wireless transmission.

[0032] It should be noted that since the abnormal braking parameter information comes from the output of the sensor and the on-board ATP, as long as the data input from any one of the two channels is abnormal, or both channels are abnormal, it will be recognized by the vehicle's information control device, thereby further improving the safety factor.

[0033] S102. The train rear-end collision prevention device calculates the braking distance of the current train according to the braking parameter information, the current train speed and the distance to the front adjacent train.

[0034] Specifically, Figure 2 As shown, the information control device of the rear train can send the braking parameter information to the on-board ATP, which then forwards it to the on-board train automatic driving system (Automatic Train Operation, ATO). The on-board ATO calculates the braking distance of the current train based on factors such as the distance between the vehicle and the adjacent train in front and the relative speed of the front and rear trains.

[0035] S103: When the braking distance is greater than a first threshold, the train rear-end collision prevention device adopts a train braking strategy.

[0036] It should be noted that since the abnormal braking parameter information is directly transmitted to the rear train after being specially measured by the information control device of the adjacent train in front, the rear train has already known the status of the front train when it first discovers that the adjacent train in front has a tendency to brake abnormally. In this way, it can combine the data of the front train and its own operating status at that time to process its own operating status more timely and efficiently. This allows the train to move forward or perform emergency braking more timely and safely, thereby maximizing the driving safety of the line's operating trains.

[0037] In the embodiment of the present application, since the braking parameter information of the adjacent train ahead can be obtained and the braking distance of the current train can be calculated based on the braking parameter information, the train braking strategy can be adopted when the braking distance is greater than the first threshold. In this way, it can be determined during the operation of the train whether emergency braking measures are needed to prevent a rear-end collision with the preceding vehicle, thereby avoiding the occurrence of train rear-end collision accidents, thereby improving the train safety factor, train operation efficiency and passenger riding experience.

[0038] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method. In order to realize the above functions, it includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiment disclosed herein, the embodiment of the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0039] In the train rear-end collision prevention method provided in the embodiment of the present application, the execution subject may be a train rear-end collision prevention device, or a control module for train rear-end collision prevention in the train rear-end collision prevention device. In the embodiment of the present application, the train rear-end collision prevention method is executed by a train rear-end collision prevention device as an example to illustrate the train rear-end collision prevention device provided in the embodiment of the present application.

[0040] It should be noted that the embodiment of the present application can divide the functional modules of the train rear-end collision prevention device according to the above method example. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. Optionally, the division of modules in the embodiment of the present application is schematic and is only a logical functional division. There may be other division methods in actual implementation.

[0042] Optionally, the acquisition module 301 is used to receive the braking parameter information sent by the front adjacent train, and the braking parameter information is information collected by a sensor device of the front adjacent train.

[0043] Optionally, the sensing device includes at least one of the following: an onboard automatic train protection system ATP and sensors installed on the inner sides of the wheels at the front and rear ends of the train.

[0045] Optionally, the braking parameter information includes one or more of brake pedal displacement, brake cylinder pressure, brake pedal pedal speed, train speed information before and after the brake pedal is stepped on, operating parameter information of each component in the braking system, and overall output torque information of the braking system.

[0046] In the embodiment of the present application, since the braking parameter information of the adjacent train ahead can be obtained and the braking distance of the current train can be calculated based on the braking parameter information, the train braking strategy can be adopted when the braking distance is greater than the first threshold. In this way, it can be determined during the operation of the train whether emergency braking measures are needed to prevent a rear-end collision with the preceding vehicle, thereby avoiding the occurrence of train rear-end collision accidents, thereby improving the train safety factor, train operation efficiency and passenger riding experience.
