Expressway RFID vehicle monitoring system based on optical fiber network

Abstract

Present invention discloses a speedway vehicle real-time monitoring processing system to optical fiber network based on wireless RF identify (RFID) technologic technology. It contains installing built-in intelligent controller reading head on top of highway emergency telephone booth, When vehicle installed with RF identification card run into effective monitoring range, intelligent controller controlling reading head sending radio-frequency signal through microwave antenna, RF identification card generating induced current and transmitting telephone booth correlative position encoding etc relevant information which is red by reading head through aerial, and resolving, saving, transmitting and displaying on central server and connected visiting termination, to obtain graphic vehicle real-time information using control supervisor information system.

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...

AI Technical Summary

Problems solved by technology

Generally speaking, the construction of expressway optical fiber network has a large investment and advanced facilities, but the utilization rate is very low, resulting in a huge waste of resources

[0005] Existing technologies have solved some of the difficulties in highway vehicle monitoring, but the above-mentioned technologies still have deficiencies, which are highlighted in: the GPS system is complex in technology, high in cost, and has a considerable degree of instability; the RFID vehicle system must use wireless Network, slow speed, low accuracy
