Intelligent spike for road vehicle detection

Abstract

An intelligent spike for road vehicle detection comprises an energy harvesting unit, an energy storage unit, an energy management unit, a light prompting unit, a sensing unit and a low-power-consumption wireless communication and control unit; the light prompting unit and the sensing unit are connected with the low-power-consumption wireless communication and control unit, the energy harvesting unit, the energy harvesting unit and the energy management unit are connected, and the intelligent spike is arranged in the middle of the road surface of a lane or the center line of the road surface of the lane of the road surface of a road edge; when a vehicle runs on the lane, the spike senses road vehicles, and related traffic information such as traffic flow, time occupancy ratio, vehicle speed and vehicle models are obtained by detecting magnetic wave changes caused in the vehicle running process.According to the intelligent spike for road vehicle detection, installation and maintenance are easy, operation is stable, the size is small, the cost is low, the power consumption is low, and vehicle running inducing and safety assist functions are achieved by means of the modes such as active wireless information interaction between the intelligent spikes and between the intelligent spikes and the vehicles and vehicle passive sensing.
