Rersearch Of Highway Information Collection And Processing System Based On Rfid Internet Of Things

In the past few years, the development of Highway was rapidly.However, the highway management level far behind the road construction, Traffic congestion, traffic accidents still frequently happened. The emergence of the Internet of Things provides a new option for the management of the highway, Internet of things used in the highway system can be people, cars, road closely integrated with the highway,and the management of Highway will become more convenient. One of the key technologies in the Internet of Things RFID technology is an advanced automatic identification technology which has the advantages of the further identify distance and the faster identification. The highway information acquisition and processing system is based on radio frequency identification technology to achieve the collection of highway vehicle information, Thus the information collected for analysis, processing, and get the traffic information finally.This paper is mainly based on RFID technology to complete the hardware circuit design of the highway information collection system, complete the controller module circuit and RF module circuit design; Controller chip select ATmegal6L, and finish the reset circuit、 memory expansion circuit and interface circuits of the peripheral; the RF module circuit selects R1000reader chip; the paper also finish the design of highway information processing platform, completed the design of highway traffic information database based on SQL Server2000database; at the end of the article, we carried out the highway information acquisition and processing system software design, mainly to complete the controller program design, the reader module design and information processing system design.
