Abstract

The invention relates to a remote self-powered traffic flow automatic detection device, system and method. The device comprises a load transfer module, a signal generating module, a signal processing module and an energy storage module. The load transfer module transfers a road vehicle axle load signal to the signal generating module. The signal generating module converts the road vehicle axle load signal into an AC signal. The signal processing module processes the AC signal to obtain a traffic flow signal. The energy storage module converts the AC signal, stores the AC signal in the form of electrical energy, and supplies power to the signal processing module. The signal generating module of the invention directly converts the vehicle axle load signal into the AC signal, calculates the traffic flow signal through the AC signal, avoids the interference of surrounding environmental factors on measurement data, and greatly improves measurement accuracy. The AC signal can be stored directly in the energy storage module after being processed to power the signal processing module to achieve self-powering of the detection device.

Description

technical field [0001] The invention relates to the technical field of traffic detection, in particular to a remote self-powered traffic flow automatic detection device, system and method. Background technique [0002] With the development of economy and industry, automobiles have been gradually popularized, which has also led to increasing traffic congestion on the road. In order to solve the problem of road congestion, intelligent traffic is an inevitable trend. Intelligent traffic includes real-time detection of traffic flow and intelligent diversion measures. At present, traditional traffic flow detection mainly relies on magnetic induction detection technology based on magnetic induction coils and wave frequency detection technology based on ultrasonic waves, radar waves, infrared rays, etc. The magnetic induction coil detection technology calculates the vehicle flow data through the change of the inductance of the energized coil caused by the movement of the metal ca...
