Abstract

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

A kind of ultrasound examination sky parking lot device and detection method thereof

Technical field

The invention belongs to detection technique field, sky parking stall, empty particularly to a kind of ultrasound examination Parking lot device and detection method thereof.

Background technology

At present, along with being continuously increased of motor vehicle number, the problem of large-and-medium size cities parking difficulty More and more prominent, in order to improve the service efficiency on parking stall and save car owner's time, at present, adopt Parking stall monitoring and managing method have: personal monitoring, monitoring ultrasonic and image recognition monitoring.People Work monitoring is lost time, and consumes manpower；Illumination is required by image recognition monitoring, place's adjustment Method is the most complicated；Monitoring ultrasonic is then to install detection at top, each parking stall or bottom, passes through The change of distance has monitored whether that vehicle, each parking stall must install ultrasonic listening, equipment Waste is serious.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of ultrasound wave The empty parking lot device of detection and detection method thereof, utilize ultrasonic scanning to find range, and by processing Range data identifies whether there is empty parking space, convenient, simple and direct, easily implement, and can effectively solve to stop Parking lot parking stall measure problem.

To achieve these goals, the technical scheme is that

A kind of ultrasound examination sky parking lot device, includes ultrasonic range finder 1, ultrasonic Motor 2 is installed bottom ripple diastimeter 1, motor 2 be divided into horizontal rotation motor and Vertical rotary motor, can drive ultrasonic range finder 1 to rotate；Described ultrasonic range finder 1 It is connected with computer 3 two-phase；The outfan of computer 3 connects motor 2.

A kind of ultrasound examination sky parking stall method, step one, at parking position to be detected Ultrasonic range finder 1 installed above, with installation site as summit, motor 2 controls ultrasonic Ripple diastimeter 1 rotates range finding, and finding range is cone；When range finding starts, by computer 3 Sending instruction makes motor 2 be expanded to maximum perpendicular angle, begins preparing for horizontal rotation and surveys Away from；When rotated, often cross certain angle the most once to find range, by measurement result by wireless Transmission is to computer 3 backstage；Until after gathering the data of maximum angle one circle, motor 2 Reduce vertical angle, carry out second time and horizontally rotate range finding；So circulation range finding is until being justified All data of cone scope, including angle value and distance.

Step 2, when computer 3 background process data, owing to ultrasonic range finder 1 is with every Distance between individual parking stall determines that, so according to the measurement result of transmission, if measured Between result and former measurement distance, error is more than 0.5 meter, then this parking stall stop over can be described Park, otherwise, illustrate that this parking stall is vacant, and come by vertical angle and level angle The position on each parking stall corresponding；Parking person can observe the vacant feelings in parking stall by computer 3 Condition, is simultaneously emitted by order and manually detects a certain parking stall or whole parking stall, it is possible to arrange week Phase is detected automatically.

Beneficial effects of the present invention:

This ultrasound examination parking stall method makes ultrasound wave by computer-controlled stepper motor Diastimeter rotates, and testing result intuitively reflects on computers, it is simple to management；One group sets For multiple parking stall can be detected, save material resources；Environment limits less, is applicable to underground Or parking lay-by.

Accompanying drawing explanation

Fig. 1 is the theory diagram of the present invention.

Fig. 2 is the scheme of installation of the present invention.

Fig. 3 is the supplementary structure figure of the present invention.

Specific implementation method

Below in conjunction with the accompanying drawings the present invention is described in further details.

As it is shown in figure 1, a kind of ultrasound examination sky parking lot device, include ultrasonic ranging Instrument 1, is provided with motor 2 bottom ultrasonic range finder 1, and motor 2 can drive Ultrasonic range finder 1 rotates；Described ultrasonic range finder 1 is bi-directionally connected with computer 3； The outfan of computer 3 connects motor 2.

The present invention includes whether ultrasonic range finder 1, detection vehicle exist；Motor 2, Rotary ultrasonic ripple diastimeter carries out the scanning range finding that coverage is cone；Computer 3, if Put the ultrasound examination cycle, and result is shown over the display.

As in figure 2 it is shown, ultrasonic range finder 1 is arranged on above parking lot, motor 2 Accept computer 3 order control ultrasonic range finder 1 to rotate, simultaneously to ultrasonic range finder 1 Sending sense command, detecting position is set to automobile top, and finding range is cone.

Embodiment 1:

Ultrasonic range finder 1 and motor 2 are controlled by computer 3.When range finding starts, Being sent instruction by computer 3 makes motor 2 be expanded to maximum perpendicular angle, begins preparing for water Flat rotation is found range.When rotated, often cross certain angle the most once to find range, by measurement result By being wirelessly transmitted to computer 3 backstage, until after gathering the data of maximum angle one circle, step Enter motor 2 and reduce vertical angle, carry out second time and horizontally rotate range finding.So circulate range finding, Until obtaining all data of circular cone scope, including angle value and distance.

The data being sent to computer 3 backstage are processed by computer 3.Due to ultrasound Distance between distance meter 1 and each parking stall determines that, so according to the measurement knot of transmission Really, if error is more than 0.5 meter between measurement result and former measurement distance, then this can be described Parking stall parked vehicle, otherwise, illustrate that this parking stall is vacant, and pass through vertical angle With the position that level angle comes each parking stall corresponding.

Parking person can observe the vacant situation in parking stall by computer, is simultaneously emitted by order and manually examines Survey a certain parking stall or whole parking stall, it is possible to the cycle that arranges is detected automatically.
