Embodiment Construction

[0022] refer to figure 1 , install the RF identification card 4 on the windshield of the vehicle 5, or install it on other suitable places as required, such as the side of the vehicle body. The reading head 1 with the built-in intelligent controller is installed on the top of the expressway emergency telephone booth 6, and is connected with the central server 8 installed with the control management information system through the expressway optical fiber network 7. The microwave antenna 3 is placed in a suitable position beside the telephone booth 6 .

[0023] When the vehicle 5 equipped with the RF identification card 4 drives into the effective monitoring range of the expressway, the intelligent controller 2 controls the reading head 1 to send a radio frequency signal of a certain frequency through the microwave antenna 3, and the RF identification card 4 generates an induced current and sends out The position code and other related information related to the telephone booth...

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...
