Problems solved by technology

[0004] To sum up, the limitations of the existing train integrity detection methods are: (1) Only by manual comparison of the wind pressure at the head and tail of the train, after a longer train is braked, the corresponding time for the change of the wind pressure at the tail will also be longer ; (2) After the integrity of the front vehicle is lost, it cannot be reported to the rear vehicle in real time; (3) Once the front vehicle breaks the coupling, the time for the front vehicle to judge the loss of integrity is longer, and the braking time of the rear vehicle is shorter , increased security risks

Embodiment 1

[0046] figure 1 is a schematic structural diagram of an example train integrity detection system 1000 according to an embodiment of the present invention, as figure 1 As shown, the system may include: a first positioning device 200 and a second positioning device 300, which are respectively installed at the train head 601 and the train tail 602 of the train 600 for detecting train positioning data. For example, the first positioning device 200 and the second positioning device 300 can use any appropriate positioning system or technology, such as Beidou satellite positioning, GPS, etc., and the first positioning device 200 installed at the head of the train 601 (ie, the front of the train) can To detect the positioning coordinates of the row head, the second positioning device 300 installed at the row tail 602 (ie, the train tail) can detect the row tail positioning coordinates. The tail equipment 400 is installed at the rear of the train (i.e. the tail 602) for detecting wind...

Embodiment 2

[0049] figure 2 is a schematic structural diagram of an example train integrity detection device 100 according to an embodiment of the present invention, as figure 2 As shown, the device can include: an acquisition module 11, which is used to acquire train positioning data and column tail wind pressure data, for example, the acquisition module 11 can be a wireless communication module (such as a wireless transceiver unit, etc.), to obtain the above-mentioned train integrity The first positioning device 200, the second positioning device 300, and the train end device 400 in the detection system 1000 obtain the train positioning data and the train tail wind pressure data; and the processing module 12 is used for according to the train positioning data and the Train tail wind pressure data to determine if the train is complete. The processing module 12 can fuse the train positioning data and train tail wind pressure data according to different judgment logics.

Embodiment 3

[0060] In this embodiment 3, an integrity determination method different from the judgment logic of the processing module 12 in embodiment 2 is provided, wherein a redundant judgment process is set, that is, a satellite positioning device is used in areas with strong satellite signals The positioning information provided and the wind pressure change are used to detect the integrity of the train. In areas where the satellite signal is weak, the method of detecting the integrity of the train by wind pressure change is used to make up for the lack of satellite positioning. In order to achieve the above purpose, the processing module 12 may be configured to: when the train positioning data is acquired, determine whether the train is complete according to the train positioning data and use the determined result as the first result, Determine whether the train is complete according to the column tail wind pressure data and use the determined complete result as the second result, dete...

Abstract

The invention relates to the technical field of railway signals and discloses a method, a device and a system for detecting train integrity. The method comprises acquiring train positioning data and train tail wind pressure data, and determining whether a train is integral according to the train positioning data and the train tail wind pressure data. The method, the device and the system for detecting the train integrity provided by the invention can accurately and effectively determine whether the train is integral according to the train positioning data and the train tail wind pressure data acquired in real time, so as to effectively reduce the labor intensity of drivers and passengers while improving the operation efficiency of the freight train and the driving safety coefficient, thereby meeting the development trend of heavy load and high density of freight railway.

Description

technical field [0001] The present invention relates to the technical field of track signals, in particular to a train integrity detection method, a train integrity detection device, and a train integrity detection system Background technique [0002] Freight railways usually use trains in locomotive mode, that is, the basic combination of 1+N (1 locomotive + N cars), which has the characteristics of flexible marshalling and large load capacity. Since locomotives and vehicles themselves cannot provide train integrity information, freight railway trains need on-board equipment (ie, on-board train operation control equipment) to check and judge the integrity of the train. [0003] In the prior art, freight railways are mostly located in mountainous areas, and the bridge-to-tunnel ratio of the line is very high. The train driver mainly detects the wind pressure at the tail of the train and manually judges the integrity of the train. During the operation of the train, the press...
