Abstract

The invention discloses a speed measurement system and a speed measurement method based on double geomagnetic sensors, which mainly solve the problems of high cost and complex installation of the existing speed measurement system, and comprise a double geomagnetic sensor module, a base station, a data processing module and a data reporting module. The input end and the output end of the data processing module are respectively connected with the double geomagnetic sensor module and the data reporting module, and the data reporting module is wirelessly connected with a base station module; two geomagnetic sensors A and B in the double-geomagnetic-sensor module collect magnetic field data around the geomagnetic sensors A and B respectively, transmit the magnetic field data to the data processing module to be stored, judge whether a vehicle passes through the detection range of the sensors or not according to the data, calculate the speed of the vehicle and output the speed to the data reporting module. The data reporting module sends the vehicle speed information to the base station, and the base station reports the received vehicle speed data sent by the data reporting modules to thetraffic data analysis platform. The invention is low in cost, convenient to install, beneficial to large-scale deployment and capable of being used for highway intellectualization.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and further relates to a speed measurement system of a geomagnetic sensor, which can be used to detect the speed of motor vehicles to realize road intelligence. Background technique [0002] Transportation is the main driving force for urban development. The sharp increase in car ownership has caused increasingly severe traffic jams, traffic accidents, and environmental pollution, seriously restricting urban social and economic development, so traffic reform is urgent. Road intelligence is the key to solving the above traffic problems and supporting the sustainable development of cities. my country has listed intelligent networked vehicles as a national development strategy. As a key part of building a comprehensive sensory body for people, vehicles, roads, and networks, smart roads will be combined with intelligent driving technology to strongly support the application of aut...
