Abstract

The invention provides a method and a system for vehicle information extraction. The vehicle information extraction system comprises a sending end and a receiving end. The sending end comprises a sending side MCU, a sending side contact detector module, and a sending side Zigbee wireless data transmission module. The receiving end comprises a receiving side MCU, a receiving side contact detector module, and a receiving side Zigbee wireless data transmission module. A contact method is used to detect whether a vehicle passes through, and according to time difference that a vehicle passes through the two contact detector modules, vehicle speed information is calculated. Compared with a non-contact detection method, the method is more reliable, and is little disturbed by external disturbance,and the method is more accurate and effective. A Zigbee communication technology is used, the system can communicate with large quantity of nodes. A mature Zigbee protocol stack is used, wireless transmission is very reliable, and effective transmission of signals is guaranteed. The system and the method reduce packet loss probability, and effectively prevent interference of unrelated Zigbee equipment connection on normal work of other equipment in the system. The system collects large amount of vehicle information, and the information is used for big data analysis, providing convenience foreffectively mastering road information.

Description

technical field [0001] The invention belongs to the technical field of vehicle information extraction, and in particular relates to a vehicle information extraction method and system. Background technique [0002] The intelligent transportation system is a kind of system that effectively integrates advanced information technology, data communication transmission technology, electronic sensing technology, control technology and computer technology into the entire ground traffic management system, and plays a role in a wide range and in all directions. A real-time, accurate and efficient integrated transportation management system. The basis of the transportation management system is the rapid, accurate and effective extraction of vehicle information. Only by mastering the vehicle information can the intelligent transportation system play its role. [0003] At present, there are roughly the following schemes for realizing vehicle information extraction: [0004] 1. Wave freq...
