Embodiment 1
[0019] Both the ultrasonic rangefinder 1 and the stepping motor 2 are controlled by a computer 3 . When the distance measurement starts, the computer 3 sends an instruction to make the stepping motor 2 expand to the maximum vertical angle, and prepares for the horizontal rotation distance measurement. When rotating, a distance measurement is carried out every time a certain angle is passed, and the measurement result is transmitted to the background of the computer 3 through wireless, until the data of one circle of the maximum angle is collected, the stepper motor 2 reduces the vertical angle, and the second horizontal rotation measurement is performed. distance. Repeat the distance measurement in this way until all the data of the cone range are obtained, including angle values and distances.
[0020] The data sent to the background of the computer 3 is processed by the computer 3 . Since the distance between the ultrasonic range finder 1 and each parking space is determ...

Provided are a device for detecting empty parking spaces through ultrasonic waves and a detection method thereof. The ultrasonic detection device comprises an ultrasonic range finder, a stepping motor and a computer, wherein the ultrasonic range finder detects whether vehicles exist; the stepping motor controls the ultrasonic range finder to rotate and perform scanning ranging within a conical coverage; and the computer records and processes data and displays results on a display, and can set manual detection or change an ultrasonic detection period. The ultrasonic detection device is installed above a parking lot, the computer controls the stepping motor to make the ultrasonic range finder perform rotary ranging, and the ranging range is conical. Data after the ranging, which comprises angle values and distances, is processed through the computer, according to the facts that the parking spaces correspond to the angle values and states of the parking spaces correspond to the distances, results are obtained and displayed. The device is simple in structure, multiple parking spaces can be detected simultaneously, and the requirements of different parking spaces can be met.
Description
technical field [0001] The invention belongs to the technical field of empty parking space detection, in particular to an ultrasonic detection device for empty parking spaces and a detection method thereof. Background technique [0002] At present, with the continuous increase of the number of motor vehicles, the problem of difficult parking in large and medium-sized cities is becoming more and more prominent. In order to improve the efficiency of the use of parking spaces and save the time of car owners, the current parking space supervision methods are: manual monitoring, ultrasonic monitoring and image recognition monitoring. Manual monitoring is time-consuming and labor-intensive; image recognition monitoring requires light, and the processing algorithm is more complicated; ultrasonic monitoring is to install detection on the top or bottom of each parking space, and monitor whether there is a vehicle through the change of distance. Ultrasonic detection has to be install...
