INTELLIGENT E-POLICE AND TRAFFIC VIOLATION AUTOMATIC RECORDER SYSTEM FOR MODERN CITY TRAFFIC USING MOST ADVANCED WIRELESS SENSOR TECHNOLOGY IN REAL TIME.
With the rapid growth of economy, the quantity of vehicles in the city has greatly increased, as well as the number of drivers. At the same time, the situation of disobeying regulations happed more than before, which has lead to great number of damages to body and economy. Many obstacles have been made in the process of building civilized city, maintaining traffic orders and protecting personal safety. How to efficiently solve the problem of traffic crowding and regulation disobeying to avoid traffic accidents and meet the requirements of smooth traffic project have been the first important issue which the traffic administration has to urgently deal with.
e-police, also called detecting and recording system, is used to catch vehicles violating traffic rules, such as over-speed driving and red traffic light violation. The traffic rule violation is main factor of traffic accidents, chaos and traffic jams. E-police system can work all day and all night to monitor violation of red light at the intersection or detecting over-speed driving at preset checkpoints on roads.
Base on the micro Watt ultra-low power consumption technology, combined with RFID technology and wireless sensing technology, the new vehicle traffic violation detecting system have been presented.
When a vehicle passes through an electromagnetic flux sensor, it will change the field and will lead to a change of return circuit of the field. By imbedding a wireless terrestrial magnetism detector beyond the stop line at the cross road, the detector will generate an electro magnetic field which is vertical with the road surface. When vehicle pass though the detector, it just equals as a metal surface object cutting the electromagnet filed, as the magnetic flex of the field changes, and lead to a change of return circuit of the wireless magnetism detector. When the vehicle detector installed at the crossroad receives the return circuit of the wireless terrestrial magnetism detector, every signal light is equipped with a direction and signal status encoder and transmitter. The RSE (roadside equipment) monitors status of all traffic signals and the status of vehicle on the every direction of road. As per the traffic signal vehicles are moving, when any vehicle try to violate red signal the RSE will detect the particular vehicles data and sent to remote central monitoring station of police.
This system involves highly critical electromagnetic technology, state of-the-art wireless technology in 24 GHz to ensure high speed data communication.
