Automatic parking management system of unmanned parking lot

Abstract

The invention relates to an automatic parking management system of an unmanned parking lot. The automatic parking management system comprises an ultrasonic sensor unit, a Zigbee communication unit, an image identification unit, an alarm unit and a control center computer; the control center computer is connected with the ultrasonic sensor unit, the Zigbee communication unit, the image identification unit and the alarm unit; and the ultrasonic sensor unit comprises an ultrasonic generator installed on a vehicle and a plurality of ultrasonic receivers installed in a parking lot, the Zigbee communication unit is in communication connection with the vehicle, the control center computer controls the vehicle through the Zigbee communication unit, the image identification unit comprises a mesh-like identification frame disposed on the ground of an entrance area of the parking lot, the control center computer judges whether the vehicle enters the parking lot in real time through the mesh-like identification frame, and the alarm unit comprises an infrared detector for detecting whether a person enters the parking lot. Compared with the prior art, the automatic parking management system can efficiently use the land area of the parking lot and reduce time cost.

Description

technical field [0001] The invention relates to vehicle management in the field of urban traffic, in particular to an automatic parking management system for unmanned parking lots, which is suitable for intelligently managed parking lots, such as shopping malls, office building underground parking lots and the like. Background technique [0002] Parking or finding a car in a large-scale parking lot is a time-consuming and labor-intensive task, and many automated parking guidance systems have emerged as the times require. The realization of parking space guidance is to automatically guide the vehicle to a specific parking space assigned by the system. At present, street light line guidance or electronic display screen guidance is commonly used, which consists of a parking space guidance controller and some guidance indicators or parking space guidance screens. This requires pre-setting a line between the channel and the target parking space on the electronic map in the applic...
