[Abstract]:Real time and effective traffic flow parameters are the data base and decision basis of intelligent transportation system (ITS(Intelligent Transport Systems / ITSs). But the existing traffic flow parameter detection technology generally adopts the wired data transmission mode, has the very big space limitation, and the equipment volume is generally big, the system power consumption is very big, the installation way is generally more tedious, the maintenance cost is high. In addition, the existing traffic flow parameters detection technology generally only uses a single sensor information as the basis of detection, under the bad weather or pedestrian, trees and other wrong target interference, it is easy to cause false detection. In order to solve the problems of large volume, high power consumption, space limitation of data transmission mode and cumbersome installation and maintenance of the existing traffic flow parameter flow detection equipment, a miniaturization of wireless transmission technology is studied in this paper. Low power traffic flow parameter detection equipment. Based on the geomagnetic disturbance caused by vehicle driving and the change of road illumination intensity, the traffic flow parameters can be detected. On the basis of studying the technical route, the hardware and software design of the traffic flow parameter detecting equipment system is carried out. The hardware design of the system includes sensor data acquisition design, wireless communication unit design, self-supply power supply management unit design based on solar panel and PC data acquisition and control device design. The design content includes schematic design. PCB design and hardware debugging. In the system software design, the embedded program of wireless sensor node and the data acquisition and analysis software of upper computer are designed. After the system software and hardware design is completed, the system integration and test are carried out. In the process of system testing, the stability of the system and the validity of data acquisition are verified, and sufficient raw data are collected for the next step of data analysis. Finally, based on the analysis of sensor data, a traffic flow parameter acquisition algorithm based on geomagnetic and light-induced information fusion is proposed. The experimental results show that the traffic flow parameter detection equipment studied in this paper uses two kinds of sensing information as the detection basis and effectively improves the anti-interference ability and detection accuracy of the detection equipment.
