Embodiment Construction

[0039] When considering how to improve the accuracy and reliability of vehicle number recognition, if we follow the conventional thinking, the more comprehensive vehicle number recognition technology means, the higher the accuracy will be, but it will also make the solution more cumbersome, complex and resource-intensive The amount will also be larger. In the process of creating the present invention, the inventor found that if the independence of the identification technical means cannot be guaranteed, the increase of the identification means will only increase the complexity and complexity of the scheme, but cannot guarantee the accuracy of the verification. After many studies And after the test, a scheme (that is, this application) that combines two independent (that is, signal sources, detection equipment, and detection methods are all independent of each other) vehicle number recognition technical means is used to check each other, thereby better ensuring the vehicle numbe...

Abstract

The invention relates to an automatic equipment identification (AEI) method and an AEI system. The AEI method includes the following steps: monitoring tag information carrying a train number and sent by a train radio frequency identification (RFID) tag, and starting a camera device to take an image of the area on a train where a train number is located; after positioning a character zone in the image and splitting the character zone from the image, identifying the train number in the character zone; comparing the identified train number and the train number sent by the RFID tag, sending data indicating the train number to an external preset address if the identified train number is identical to the train number sent by the RFID tag, and sending an alarm message if the identified train number is not identical to the train number sent by the RFID tag. The invention adopting the technical scheme has the advantages that the automatic image identification method and the RFID tag identification method are creatively combined, and the results from the two methods verify each other, so as to reduce wrong and omitted train number reading, and improve the AEI accuracy.

Description

technical field [0001] The present invention relates to the technical field of railways, in particular to a method and system for identifying train numbers. Background technique [0002] China Railway has a large number of vehicles. When each vehicle enters the station, it needs to record the vehicle number and other information of the vehicle. The traditional method uses oral reading, notes, and hand-written manual methods to record and summarize the vehicle number, and the work efficiency is low. And error-prone. [0003] In order to solve the problem of low work efficiency and error-prone problems caused by traditional methods, the currently widely used automatic equipment identification (AEI) installs electronic tags on each vehicle, and installs AEI equipment on the track to collect vehicle entry and exit. library information. [0004] However, in the process of creating the present invention, the inventor found that the above-mentioned prior art has at least the prob...
