The Vehicle Guidance System for Underground Parking Lot Based on Internet of Things

To improve the intelligent management level of the underground parking lot, a vehicle guidance system based on the Internet of Things technology is proposed to update the transformation of traditional parking lot conveniently.The system uses ultrasonic to collect vehicle information and uses Zigbee technology to transmit and receive data.The vehicle guidance system of the upper computer integrates the parking space information of the parking space detection node and the traffic flow of the vehicles in and out to avoid regional congestion fully.In this case, the driver walks the shortest way to the elevator after parking under the optimal path guidance.The experimental simulation result shows that the system guides the vehicles hierarchically, staggers parking, and reduces the congestion and chaos caused by the influx of multiple vehicles, which enables the driver to choose the best parking space.The system provides the guiding path from the entrance to the best parking space, and improves the disadvantage that the vehicle guidance system of the parking lot is low in intelligence, and improves the management efficiency of the parking lot.
