Description

technical field

[0001] The invention belongs to the field of vehicle monitoring systems, and in particular relates to a processing system for realizing real-time monitoring of highway vehicles by using a radio frequency identification (Radio Frequency Identification, RFID) technology based on an optical fiber network. Background technique

[0002] With the development of wireless communication technology, GPS technology has been widely used in the tracking, positioning and monitoring of ground moving targets. Especially after the United States lifted the SA restrictions, its positioning accuracy and reliability have been greatly improved. The popularity of GSM (Global Public Digital Mobile Network) provides a reliable guarantee for the wide application of GPS technology, making information transmission more convenient and efficient, and also reducing the operating cost of the GPS system by a large margin. However, the positioning accuracy of the GPS system is seriously affe...
