The invention discloses a traffic volume collection system and method based on a geomagnetic sensor. The system comprises the geomagnetic sensor, a collection control base station and a traffic guidance information issuing platform. The geomagnetic sensor mainly comprises an earth magnetic field sensor, a microcontroller and a wireless data transmission module. The collection control base station comprises a wireless communication module, a base station MCU, a 3G router and a power module. The traffic guidance information issuing platform comprises a data collection unit, a data analysis unit and a guidance issuing unit. The geomagnetic sensor is buried below the road surface of a traffic intersection. Through the traffic volume collection method, traffic volume data can be measured by detecting earth magnetic field data, and the defects that existing traffic volume collection methods adopt probe vehicles and cameras to collect the traffic volume and real-time and accurate guidance can not be truly realized are well overcome.
Description
technical field [0001] The invention belongs to the technical field of vehicle detection, and relates to a system and method for intelligently monitoring road traffic volume in real time, optimizing passing time, preventing traffic jams at intersections, reporting relevant information to a command center and releasing real-time traffic guidance information through sensing by an earth magnetic field sensor . Background technique [0002] With the development of the economy and the improvement of people's living standards, cars are getting closer and closer to people's lives, and the importance of intelligent transportation such as intelligent guidance of traffic flow is increasing day by day. At present, traffic guidance often uses data collected by floating cars and cameras. The data sampling is unreasonable, the collection cost is high, and there are large blind spots, which is not conducive to the overall traffic regulation and guidance.
