Wireless Vehicle Detection System


Wireless vehicle detection is a kind of new vehicle detection system which extensively used in urban traffic vehicle management to collect and transmit traffic flows and status on urban roads to front-end signal controllers and center database.


Currently, this detection technology is available from a small wireless unit (VD) which is installed, by core drilling a small hole in the surface of the carriageway (geomagnetic detector) to measure the Earth's magnetic field change when a vehicle passes by. This will be t ransit as a wireless signal to Routers under 2.4GHz wireless frequency, which can be processed by a Data Acquisition Center Device to generate a variety of traffic data, including vehicle presence signal, speed, headway time, occupancy time, vehicle distance, vehicle length and road saturation


Features and Advantages


  • Reduced installation costs

  • Easy installation & maintenance

  • Powerful wireless signal (18dbm)

  • Long battery life of 5 years

  • High detection accuracy rate

What is a traffic signal control system?

图片
With the ever-increasing usage of roads by motorists and pedestrians, an efficient traffic signal control system becomes inevitable. This guide looks into the basics of a traffic signal control system. A traffic signal control system is a network of electrically or mechanically control electronic traffic lights that regulate the flow of vehicles and pedestrians at an intersection. It is mainly composed of the main controller, vehicle detectors, control circuit, timer, decoder drive circuit, decoder, clock signal generator, and a digital decoder display drive circuit. All these works together in detecting traffic and relaying this information to the main controller which transmits the messages to the traffic signals. How a traffic control system works A traffic  signal control system  consists of different signals directing different routes in and out of an intersection being controlled by a central command controller. The main controller is the brain that takes traffic trends sent by t
