Embodiment 1

[0027] see figure 1 , is the realization flowchart of a kind of railway locomotive car number identification method of the present invention, as shown in the figure, this method can be realized by following steps:

[0028] Step S101 , at least acquiring wheel pulse signals output when the wheels of the locomotive pass through the wheel sensors arranged on the rails in the detection area.

[0029] In the specific implementation, since the number of wheels of each car in a train is fixed, the number of wheels of the locomotive passing through the detection area can be obtained through the wheel sensor, and the car sections in the train can be identified according to the output wheel pulse signal. number.

[0030] In addition, in the prior art, the approaching direction of the locomotive can also be determined through wheel sensors.

[0031] Step S102, at least read the signal including the number information of the locomotive sent by the electronic tag installed on the locomot...

Embodiment 2

[0046] See figure 2 , is a principle diagram of a railway locomotive number recognition system of the present invention, as shown in the figure, the system may include: a wheel sensor 10, which is arranged on the rail in the detection area, and at least obtains the wheel pulse output when the wheels on the locomotive pass by signal; the radio frequency identification device 20 at least reads the signal sent by the electronic tag installed on the locomotive and includes the locomotive number information, and obtains the passing message of the locomotive according to the signal, and the passing message Including at least the number of locomotives passing through the detection area and the car number of each locomotive; wherein, it also includes: a signal transmission module 30, which sends the obtained wheel pulse signal to the image acquisition device 40; the image acquisition device 40, according to the wheel The pulse signal triggers the locomotive to be photographed, obtain...

Abstract

The invention provides a locomotive number identification method and system. The method includes the steps that wheel pulse signals output by wheel sensors when wheels on locomotives pass through the wheel sensors arranged on a rail in a detection region are obtained; a radio frequency identification device is used for reading signals including locomotive number information and sent by electronic tags installed on the locomotives, and a locomotive passing message of the passing locomotives is obtained according to the signals, wherein the locomotive passing message at least comprises the number of the locomotives passing through the detection region and the locomotive numbers of all the locomotives; the obtained wheel pulse signals are sent to an image acquisition device; according to the wheel pulse signals, the image acquisition device is triggered to take photos for the locomotives, so that multiple locomotive number photos are obtained, and the multiple locomotive number photos are correspondingly correlated to the wheel pulse signals; and the multiple locomotive number photos are identified, the number of the locomotives and the locomotive numbers of all the locomotives in the locomotive passing message are checked according to an identification result. By the adoption of the method, the identification accuracy can reach over 99.99%.

Description

technical field [0001] The invention relates to the technical field of railway locomotive management, in particular to a method and system for identifying the number of a railway locomotive. Background technique [0002] With the development of the railway industry, the number of train locomotives is increasing, and the locomotive management system is also required to be more accurate, efficient and reliable. At present, the identification of railway locomotives is mainly realized through RFID identification. This solution has the characteristics of high RFID identification accuracy and fast speed, but the premise is that the locomotive tags must be intact. Its disadvantage is that it is subject to external factors. If there is a problem with the locomotive label or the identification equipment, the recognition rate cannot reach the expected expectation, which makes it difficult to effectively manage and dispatch locomotives. Contents of the invention [0003] In view of ...
