Design of intelligent infrared vehicle detect system based on ZigBee

In recent years, with the development of China´s economy and the urban vehicles increased greatly, the intelligent parking system is developing rapidly all over the country. As the important part of an intelligent parking system, vehicles and the traffic volume detection technology is also in continuous developing. The practical and feasible infrared detection technology has been widely used in traffic volume detection. The article presents a ZigBee-based infrared vehicle detect method, which can scan vehicles synchronously by installing infrared transmitting tube and receiving tube separately on each side of the road. When a car pass through the detection area, the detector can accurately and quickly judge the existence of the vehicles and record the information for traffic volume detection. According to the counts of sensors being intercepted, the location of the car and the car´s other information such as the shape, height etc. can be used to determine the car´s model, and then may give out corresponding control. In addition, the detect system first use ZigBee wireless network, which has advantages of low power consumption, low cost, low complexity and high efficiency. On the other side we can make the detector as a screen, and then make some modification, the system´s function can be more diverse, such as safety light curtain, anti-theft devices, etc. Combining with software programming, the system can detect more information, and can be reasonable optimized, especially for data processing and analysis. This detection system has wide range of uses, not only can be used in the detection of vehicle parking lot to improve the efficiency of the yard management, and also be used to detect road traffic and others, even in other areas, such as security, scientific research, mechanical control and the emerging field of intelligent building systems. With its simple structure, low cost and high stability advantages, the system has a good application prospect and developing potential.
