Description

Carriage information identification method and related device Technical Field The invention belongs to the technical field of carriage information identification, and particularly relates to a carriage information identification method and a related device. Background At present, most of thermal power plants are on line and use a plant side fuel management information system, and automatic acquisition and transmission of metering data can be basically realized. The train coal is used as an important fuel source of a thermal power plant, and links such as metering, sampling and the like after entering the thermal power plant are important. The accurate carriage information is obtained, and is the basis of the fuel management processes such as follow-up mining sampling, batch management, data statistics and the like. At present, a conventional rail scale car number recognition system of a power plant mainly relies on an RFID (Radio Frequency Identification ) antenna to recognize an electronic tag at the bottom of a carriage, obtains a car number by reading electronic license plate information, and associates gross weight, tare weight and other related data. The technical scheme mainly has the following defects and shortages in practical application: 1. the identification rate is not expected, and the identification rate of the vehicle number of the RFID system cannot achieve 100% full coverage due to the influence of factors such as label loss, pollution or faults. 2.
