The vehicle in and out port license plate recognition device is arranged at each gateway in parking lot, is configured as detection discrepancy vehicle
The number-plate number, and the number-plate number of acquisition, access time are sent to the server and stored；
The parking stall ultrasonic detector include it is multiple, be configured as with parking stall correspond, accounted for detecting parking stall
With state, when the seizure condition on parking stall changes, the status information on corresponding parking stall, state change time are sent
Stored to the server；
The road ultrasonic detector include it is multiple, be arranged at each crossing in parking lot, be configured as detection pass through
The vehicle at each crossing, when corresponding road ultrasonic detector detects that corresponding crossing has vehicle to pass through, vehicle is passed through
Time sends to the server and stored；
The server, it is configured as receiving the Car license recognition information and parking stall and road information of collection, determines car in real time
Stop position, and optimal route from gateway to the stop position is determined, to the corresponding parking stall in the optimal route
Ultrasonic detector and road ultrasonic detector send control command, its indicator lamp is worked, and realize that light guides.
Further, the server is connected with the network switch, is visited with parking stall ultrasonic detector and road ultrasonic wave
Survey device and carry out network service.
Further, the parking stall ultrasonic detector includes micro controller module, ultrasonic wave transmitter module, ultrasonic wave inspection
Receiving module, communication module, power module and indicating lamp module are surveyed, wherein, micro controller module and ultrasonic wave transmitter module, surpass

It is fed to enquiry module；
The network switch is used as network transmission, solves the problems, such as that transmission radius is long；
The course of work is：
The first step, when vehicle reaches Entrance, camera has detected that vehicle is captured after, now car plate
Identifying system extracts the license board information of the car, and the number-plate number is retrieved in database to being identified in the picture of candid photograph
Relevant information, if fixed vehicle, then continue to check the term of validity that the vehicle corresponds to parking stall, banister is opened before the deadline
Open, and open entrance to the light fixture of crossing ultrasonic detector on the path of parking stall, if not before the deadline, system is by the car
It is considered as interim vehicle；If interim vehicle, system is that vehicle distributes an optimal parking stall, and now management server will stop
Position information, license board information and drive into the time and correspond and be saved in database, then banister is opened, time that vehicle drives into record
For initial time t0；
Second step, the control command of the light fixture on the path is issued to corresponding network node, network node again will control
Order processed is forwarded to corresponding road ultrasonic detector, and road ultrasonic detector performs control command, passes through the sudden strain of a muscle of light
The bright effect for reaching route guidance；As shown in fig. 6, the road ultrasonic detector light fixture that represents of rhombus is closed mode, star
The road ultrasonic detector light fixture represented is flicker state；
3rd step, as shown in Fig. 2 after vehicle drives into parking lot, system is visited using three ultrasonic waves at first crossing
Device a, b, c the state change time are surveyed, judges the first paragraph driving path of vehicle；
The road speed of tri- junction detectors of a, b, c at first crossing is reached from Entrance should have one rationally
Scope, we are defined [Vmin1, Vmax1]；
Wherein,
Wherein, D1nEntrance reaches the distance at first crossing, Tmin1With Tmax1Value to parking lot actual environment
Test is carried out to obtain with debugging；
The actual travel speed v in system-computed first paragraph path1n=D1n/ t, wherein t are that the parking stall actually occurs state change
The time of change, utilize tn-tn-1It can be calculated, in porch t=t1-t0；
If v1n∈[Vmin1, Vmax1], then v1nEffectively, corresponding path is active path l01；
If as shown in Fig. 2 drive into parking lot [T in vehiclemin1, Tmax1] in the time, ultrasonic detector c detects vehicle
By, while detector a and b is to detect that vehicle passes through or detects that vehicle elapsed time is unreasonable, you can judge vehicle
It is the direction straight trip along entrance → c；
4th step, judge whether vehicle travels along path planning.System compares the first paragraph path of vehicle actual travel
It is whether consistent with the first paragraph of the optimal path of systems organization.If vehicle running path is inconsistent with path planning, system base
New route is planned in vehicle real time position, lamp switch order is issued to corresponding road ultrasonic detector, by new route
Light fixture is opened, and the light fixture of original route is closed, and plays the effect of light real-time navigation；If driving path is consistent with path planning,
Switch lamp order is not performed；
The path planning can use ant group algorithm, genetic algorithm, neural network algorithm, Dijkstra etc. to commonly use optimal road
Footpath computational methods；The starting point of new route is the position of a upper ultrasonic detector for detecting the vehicle behavior, and terminal is to be
The parking stall of system distribution；
5th step, judging vehicle, whether in c → d sections, VEHICLES MUST PARK WITHIN THE MARKED BAY.Due to being single file between ultrasonic detector c and d
Road, so vehicle will be travelled along c → d direction.After ultrasonic detector c detects vehicle warp, if on c → d roads
Parking space state occurs in section to be changed into taking from idle, and now ultrasonic detector is not detected by vehicle process, you can think this
VEHICLES MUST PARK WITHIN THE MARKED BAY in c → d sections for vehicle；If the section changes without parking space state, and detector d detects that vehicle passes through, you can
Think that vehicle continues to travel
6th step, d detect vehicle warp after, if e, f, g have one in effective time [Vmin2, Vmax2] within detect
Pass through to vehicle, you can think that vehicle travels along the direction, computational methods now can obtain the of vehicle traveling with the 3rd step
Two sections of path l12；
7th step, systems stay detection driving path, calculates vehicle location, VEHICLES MUST PARK WITHIN THE MARKED BAY until detecting the car, passes through
Calculate above, system can obtain a series of driving path l01、l12、l23、l34... ..., these implementation paths are added and can obtained
To the complete planning driving path l of the carall；
8th step, server store vehicle running path to database with stopping parking stall numbering, are inquired about with standby user；When
When user needs enquiring vehicle position, it can be inquired about in management service interface inputting license plate number, query interface such as Fig. 7 institutes
Show；
9th step, system issue order of turning off the light, and close the light of the ultrasonic detector flashed.
Simple reverse vehicle searching system can be realized by above workflow.
The present invention is analyzed and excavated by the vehicle behavior detected to ultrasonic detector, is explored a kind of new
Reverse car seeking scheme, relative to traditional reverse vehicle searching system, there is more obvious cost advantage and practicality.
