Parking space occupancy judgment method and device

Abstract

The invention discloses a parking space occupancy judgment method and device. The method includes: acquiring, by detection equipment, a geomagnetic value output by a geomagnetic sensor corresponding to a parking space, wherein the detection equipment comprises an ultrasonic sensor; if the geomagnetism value is less than or equal to a first geomagnetic threshold, obtaining, by the detection equipment, an ultrasonic value output by the ultrasonic sensor, wherein the first geomagnetic threshold is an upper limit value of a first preset interval; if the ultrasonic value is in a second preset interval, or the geomagnetic value is greater than or equal to a second geomagnetic threshold and less than or equal to the first geomagnetic threshold and the ultrasonic value is less than a lower limit value of the second preset interval, obtaining a first weight value and a second weight value corresponding to the geomagnetic value and a third weight value and a fourth weight value corresponding tothe ultrasonic value, and determining, by the detection device according to the first weight value, the second weight value, the third weight value and the fourth weight value, whether the parking space is occupied.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method and device for judging parking space occupancy. Background technique [0002] With the economic development of more and more family cars, parking becomes difficult, and the problem of roadside parking billing has been widely concerned. It is particularly important to judge whether there is a car parked in a parking space, that is, whether the parking space is occupied. [0003] At present, the parking detection equipment of Narrow Band Internet of Things (NB-IoT) wireless communication is a kind of equipment to judge whether the parking space is occupied, but the equipment generally has problems such as insufficient battery power supply capacity caused by high-precision detection or bottleneck. On the premise of ensuring the accuracy of judgment, how to lower power consumption has become a key issue in judging whether a parking space is occupied, which has at...
