Vehicle Loop Detector Theory Wireless Vehicle Detector Sensor  for traffic detectin system  

1.Wireless Magnetic Vehicle Detector Replace Loop

WVV130X wireless vehicle detector is based on magnetic induction technology and wireless communication 

technology. It can be easily installed on road without any wiring needs. It can collect data of traffic flow, speed of vehicle, occupancy ratio and moving direction, providing these to system integrator. The WVD wireless vehicle detection sensor is designed for pursuit of high efficiency and low cost ITS traffic application systemsBased

on magnetic detection and wireless sensor network, WVD sensors acquire the dynamic traffic flow information and send through wireless channel to user systems. Rosim ITS is successes in creating the WVD series 

wireless vehicle detector products and WAP series wireless access point, which build up a realtime wireless vehicle detection solution and traffic information monitoring system. In the past 5 more years, Rosim wireless vehicle detecting products had successfully replaced loops to monitor vehicles and the relative velocity, occupy rate and traffic flow in many projects of artery,freeway and intersection applications.

 2.Working Principle 

  By capture the tiny change of magnetism caused by the passing vehicle, WVDs (Wireless Vehicle Detectors) in the Wireless vehicle

 detection system calculate the vehicle velocity, length, type and occupy rate rapidly, and then send these information to the WAPs 

(Wireless Access Points), which will receive all the on line WVDs’ information and transmit these data to the user systems through 

RS-232/485, Internet, GPRS, etc..
