Railway freight car number identification system

Abstract

The present invention discloses a railway freight car number identification system which comprises a high-speed image acquisition device and an image identification processing unit, the high-speed image acquisition device is erected on one side of a railway track and acquires video image information of a passing freight car in real time, and the image identification processing unit is installed in an equipment room cabinet, and is used for receiving passing truck video image information transmitted by the high-speed image acquisition equipment, identifying the truck compartment type and the compartment number in real time, and outputting identification results including the compartment type, the compartment number, the identification time and the compartment number image information. According to the railway freight car number identification system, the car type and the car number printing position can be accurately positioned, the intelligent light supplementing function is achieved, and the night identification accuracy is guaranteed; and the railway freight car number identification system has a power failure parameter automatic storage function, is automatically reconnected after being restarted, does not need to be reset, ensures consistent identification rates in daytime and at night, can accurately position the carriage type and carriage number printing position, identifies the carriage type and carriage number of each carriage of a high-speed running train in real time, and outputs an identification result.

Description

technical field [0001] The invention relates to the field of railway freight cars, in particular to a railway freight car compartment number identification system. Background technique [0002] The research on the car number of railway freight cars in foreign countries was earlier. In the late 1960s and early 1970s, foreign railway systems began to study the automatic identification of car numbers. Due to the influence of technological development at that time, technologies such as color barcodes, magnetic induction, and surface acoustic waves were usually used to realize the automatic identification of trucks. High and poor anti-interference performance and other technical problems, so it has not been widely used. In the 1980s, with the continuous development of computer technology and microwave technology, many foreign companies are committed to the use of microwave reflection modulation technology to realize the automatic identification of locomotives and trucks. The hi...
