Further, described infrared distance sensor II 23, infrared distance sensor I 25 form infrared distance measuring device 4
A part, infrared distance measuring device 4 also includes MCP3001A/D converters, infrared distance sensor II 23, infrared distance measurement sensing
Device I 25 is GP2YOAO2YK type infrared distance sensors；It is defeated that the VCC of the GP2YOAO2YK infrared distance sensors connects signal
Enter, the VO pins of GP2YOAO2YK infrared distance sensors connect the IN+ pins of MCP3001A/D converters, and GP2YOAO2YK is infrared
The GND ground connection of distance measuring sensor, the UREF pins of MCP3001A/D converters connect power supply, and the CLK of MCP3001A/D converters draws
Pin connects the PA5 pins of LM4F120H5QR single-chip microcomputers, and the DO pins of MCP3001A/D converters connect LM4F120H5QR single-chip microcomputers
PA4 pins, the CS pins of MCP3001A/D converters connect the PA3 pins of LM4F120H5QR single-chip microcomputers, infrared distance sensor I
25th, infrared distance sensor II 23 is placed in control cabinet 28.
The present invention the course of work and operation principle be：
When first task of berth lock, driver is by the infrared transmitter that SE303 infrarede emitting diodes in setting about are core
Transmitting infrared signal sends high level to LM4F120H5QR monolithics to infrared receiving circuit, integrated circuit HS0038 OUT port
The reset pin of machine, and the delivery outlet of LM4F120H5QR single-chip microcomputers is connected to the reset pin of STC89C52 single chip, so as to
It can reset LM4F120H5QR single-chip microcomputers and STC89C52 single chip, automobile is parked in into camera can shoot clear scope
Interior, camera starts to identify license plate number and the license plate number remembered, STC89C52 single chip B after identifying and remembering successfully
High level is exported by P2.0 to connect electromagnetic relay 18 to triode Q2, triode Q1 colelctor electrodes hair output high level and pass through magnetic force
It is to suction out the iron block connected with spring lever in electromagnetic relay 18 from electromagnetic lock lockhole II 30 that adhesive, which will be switched, electromagnetic lock
Open, stepper motor I rotates counterclockwise 60 °, and stepper motor II, which rotates clockwise 45 °, makes slide bar I 19, camera sight and ground
Parallel, the iron block connected with spring lever in subsequent electromagnetic relay 18 is broken away from electromagnetic attraction insertion electromagnetic lock lockhole I 16；
After berth lock is unlocked, i.e., slide bar I 19 it is parallel to the ground after, resistance strain type pressure sensor I 11 and resistance-strain type
Pressure sensor II 12 is started working, and when having experienced pressure, i.e. automobile tire presses through resistance strain type pressure sensor and is in
When between resistance strain type pressure sensor I 11 and resistance strain type pressure sensor II 12, camera module and infrared distance measurement
Device is stopped, and illustrates that car has stopped；When resistance strain type pressure sensor I 11 and resistance strain type pressure sensor II 12
When having experienced pressure i.e. automobile again and producing displacement, camera I 26 and camera II 24 are started working, for shooting and recording
Ambient conditions, if the iron block that berth lock is risen and will connected with spring lever in electromagnetic relay 18 if recognizing car and leaving
Insert in electromagnetic lock lockhole II 30, and stop camera I 26 and camera II 24 and resistance strain type pressure sensor I 11 and electricity
Hinder strain pressure transducer II 12 to work, start GP2YOAO2YK infrared distance sensors II 23 and the infrared surveys of GP2YOAO2YK
Worked away from sensor I 25, if not detecting, automobile leaves, and camera is stopped after shooting 20 minutes.
Can be red by GP2YOAO2YK when having object in front of berth lock or berth lock rear is locked close to parking at one meter
Outer distance measuring sensor II 25 or GP2YOAO2YK infrared distance sensors I 23 monitor, start camera I 26 and camera II 24
Start to identify the number-plate number, if identification will not open less than the license plate number in memory, berth lock, 5 minutes rear camera cameras I
26 and camera II 24 exit work.
When berth lock by hitting energetically, I 19 pairs of resistance strain type pressure sensors III 29 of slide bar produce pressure, pass through
Resistance strain type pressure sensor III 29 exports analog signal, then is converted to data signal by A/D converter, and data signal is defeated
The P0.2 mouths entered to STC89C52 single chip STC89C52 single chip C export high level, and triode Q1 conducting buzzers 31 start
Pipe and send sound prompting alarm.
When the parking stall will change vehicle parking, as long as being answered using infrared resetting means 10 image processing module 2
Position re-recognizes license plate number.
The present invention is simple in construction, and cost easy for installation is cheap, only need to fix the device on ground, first the device
Solve and belong to the vehicle parking space of factory, company or individual problem is disorderly stopped by external vehicle；Next solves the non-intelligence of tradition
Can mechanical berth lock easily by picking lock the problem of；The finally visual identity of the device can not only identify that license plate number reaches opening car
The purpose of position lock and the image that occurs around when special circumstances occur can be recorded.The invention not only ensure that parking stall is only certainly
Used in oneself, and ensure the safety of vehicle.
The specific embodiment of the present invention is explained in detail above in conjunction with accompanying drawing, but the present invention is not limited to above-mentioned reality
Example is applied, can also be on the premise of present inventive concept not be departed from those of ordinary skill in the art's possessed knowledge
Various changes can be made.
