Hot-selling Wireless Vehicle Detection Sensor Traffic Light Sensor for Motion Detection
ROSIM ITS TECH. CO., LTD WELCOME YOU
1.Working principle :
By capture the tiny change of magnetism caused by the passing vehicle, Wireless Vehicle Detector (WVD) will send all of information on it to the access point, and then the access point aggregates the data from individual sensors and can report key traffic parameters including the vehicle velocity, length, type and occupy rate to the user systems through RS-232/485, Internet, GPRS, etc.
2.Compare loop detector:
Compare with induction Loop detector
A) Loop Detector Disadvantages:
1. severe slots and damage to road
2. large need of manpower
3. high electric power
4. long time installation
5. difficult to maintenant
B) Our Wireless vehicle detector feature:
1. easy and fast embed installation
2. less time and manpower consuming
3. wireless communication
4. no wiring, no trenching
5.long range communication, remote control
6. weatherproof, anti-press
7. wireless updating, maintenance free
3.Application: Traffic Project
(1) Adaptive traffic signal controlling
Wireless vehicle sensor detect and transmit real-time data on all directions, and Wireless Access Point get the data via antenna. The traffic controller systems get and analyses the traffic flow data, and calculate the best traffic scheme, controlling traffic lights release time. On improving transportation efficiency and saving drivers' time.
(2)Traffic flow detection system
Detector is installed in specified road, detect every vehicle pass by, and transmit the real-time information to traffic management systems via wireless access points. The user systems can calculate the traffic flows by analyzing the data.
(3)Red light and speed enforcement
Based on magnetic detection and wireless sensor networks, WVD sensors acquire the dynamic traffic flow information and send the information to Access Point installed nearby. User systems receive and process the information from Access Point, and issue instructions to electronic cameras.
(4)Corridor management
Thanks for your attention, any doubt or documents are requested, pls contact Bella freely.
