GEOMAGNETIC CHANGE situation on parking stall, realize parking stall on vehicle whether there is or not judgement.Preferably, geomagnetic sensor is earth magnetism ball.For
Prevent metal from interfering the erroneous judgement to geomagnetic sensor, geomagnetic sensor may include being embedded in the multiple key points in parking stall
Earth magnetism ball and the ground magnetic receiver being connect with multiple earth magnetism balls, ground magnetic receiver are sentenced according to the testing result of multiple earth magnetism balls synthesis
Whether there is vehicle parking on disconnected parking stall.
The operation principle that ultrasonic detection device uses is emitted using ultrasonic wave, and the transmitting of tested vehicle, echo are passed through
Time difference after reception measures tested distance, to judge whether parking stall has vehicle occupancy.The distance and other parameters surveyed are such as
Fruit reaches preset data, then judges there is vehicle on parking stall.
Ground induction coil detection device is the ground induction coil for including two to three circle conducting wires of embedment earth's surface, and together with capacitance altogether
With the oscillating circuit of composition, when the vehicle for having parking on parking stall, space medium, which changes, causes the variation of frequency of oscillation, passes through
This variation judge on parking stall vehicle whether there is or not.
Video detecting device captures parking stall image by camera, and void is arranged in the image of parking stall using image processing algorithm
Quasi- parking area judges there is parking vehicle on parking stall if analysis has the image information of vehicle in virtual parking area.
As shown in Fig. 2, parking of automobile management system module figure in an embodiment of the present invention, earth magnetism is installed on each parking stall
Rfid device 22 is arranged in parking area front in detection device, they are communicated with control device 23 respectively, geomagnetism detecting dress
The seizure condition for being responsible for detection parking stall is set, rfid device 22 is responsible for the identity of identification parking vehicle.

Rfid device 22 is arranged in parking area front in acoustic detector, they are communicated with control device 23 respectively, ultrasonic wave
Detection device is responsible for detecting the seizure condition of parking stall, and rfid device 22 is responsible for the identity of identification parking vehicle.
As described above, geomagnetic sensor, ultrasonic detection device, ground induction coil detection device, video detecting device are all
It is the detection for using different principle to realize parking stall seizure condition, but due to respective feature, and there is by external interference
Possibility, therefore the possibility for occurring judging by accident is individually likely to using any type, detected to improve parking stall seizure condition
Accuracy, can will be combined between above-mentioned apparatus, make up respective defect mutually.As shown in figure 4, another reality of the present invention
Parking of automobile management system module figure in mode is applied, the parking stall device for detecting occupation 21 installed on each parking stall is examined including ultrasonic wave
Survey device and geomagnetic sensor.Show that parking stall seizure condition can be more accurate by the testing result of both comprehensive analysis, example
As only when ultrasonic detection device and geomagnetic sensor have all detected that vehicle just can determine that there is vehicle parking on parking stall.
It should be noted that the specific combination of parking stall device for detecting occupation 21 is not described as limiting with above-mentioned, ability
Field technique personnel are on the basis of the embodiment of above-mentioned record, it is also conceivable to other combinations, such as utilize earth magnetism
Detection device, ultrasonic detection device, ground induction coil detection device, video detecting device testing result comprehensive analysis parking stall account for
Parking stall may be implemented with state or with other and occupy cooperation comprehensive analysis together with the device of detection function.
As described above, the boundary of parking area is fuzzy, one of the main reason for such case occur is, radio frequency is known
Other device overlay area is determined by radio frequency beam width, and beam angle can be influenced by environment such as external temperature, weather
It fluctuates up and down.When application is with Roadside Parking environment, the vehicle identification that rfid device may recognize includes not only vehicle
Parking vehicle identity on position, it is also possible to including vehicle identification passing on road beside parking stall, be possible to occur only in this way
There are one the seizure conditions of parking stall to change, and rfid device has recognized the vehicle of two or more different identities, this
Sample cannot find correspondence and determine on parking stall be just which specific identity vehicle in parked vehicle.
In order to overcome above-mentioned defect, it is preferable that when control device has changed according to the seizure condition of specific parking stall
Between in section t, the vehicle for the same identity that rfid device recognizes always is determined as parking vehicle.It is to be appreciated that road
Passing vehicle is the variation for not interfering with parking stall device for detecting occupation and detecting parking stall seizure condition on the road, while vehicular traffic
Time in parking area is of short duration.Therefore, only there are one having vehicle on parking stall in parking, the occupancy shape on the parking stall
State changes, and From this moment in time period t, rfid device can constantly recognize the identity of this automobile, but
The case where identity for the vehicular traffic being not excluded on road is also identified to, but vehicular traffic because can leave in a short time
Parking area so rfid device can recognize the identity vehicle in the portion of time in time period t, and works as vehicle
After leaving parking area, rfid device would not recognize the identity of vehicular traffic.Therefore, by analyzing in the period
The vehicle of which identity is recognized always by rfid device in t, and the vehicle of the identity is exactly parking vehicle.
Time period t determines that in the present embodiment, parking area is the institute on road according to the vehicle flowrate of parking area
With i.e. by present road vehicle flowrate situation be arranged, when vehicle flowrate is larger, it is believed that Vehicle Speed of passing by one's way compared with
Slowly, the value of time period t can be arranged greatly a bit；When vehicle flowrate is smaller, vehicle of passing by one's way will not be too long in parking area stop, because
This can be arranged the value of time period t a little bit smaller.In addition, in the management of parking charge in each city, there is a startings
The regulation of chargeable time, i.e. parking vehicle start not collect the charges in the set time in parking, as be in 15 minutes can be with
The regulation of Free parking just started charging more than 15 minutes, and only the vehicle of parking 15 minutes carries out parking management to a certain degree
It is upper that any meaning is not present.Therefore, time period t can also be determined according to starting chargeable time.
In specific embodiment, it may be used and buffer unit is set in control device, for being used as automotive electronics mark
The vehicle and recognition time for knowing all identity of information pool storage rfid device identification, if the spy stored in buffer unit
The vehicle for determining identity has left parking area, i.e., when rfid device cannot recognize the vehicle of the identity, by buffer unit
In all about identity vehicle identification record delete.Control device can analyze vehicle electron identifying information pool（Cache
Unit）In relevant information, whether the seizure condition changed time from parking stall lights, have in time period t lasting same
The vehicle registration information of one identity, for example, the parking space state changed time is 14：00, time period t is set as 5 minutes, can
To be inquired in vehicle electron identifying information pool, 14：00、14：01、14：02、14：03、14：04、14：Whether 05 have a certain spy
Determine the vehicle of identity, time interval can also adjust according to actual needs.
Buffer unit can also use the memory that amount of storage is bigger, storage speed is fast, it is preferable that control device is to set
It sets in the server of rear end, all records that rfid device recognizes is preserved, while also preserving each parking stall
Seizure condition information and seizure condition transformation period point information, control device is by analyzing the radio frequency identification preserved in buffer unit
The data of device identification obtain the vehicle identification stopped in parking area more than time period t, then analyze them and penetrated for the first time
The time that frequency identification device recognizes then looks for having occurred with the seizure condition of which specific parking stall of this time correlation
Variation, to find the parking stall position that correspondence determines that parking vehicle specifically stops.It is obtained for example, being analyzed in buffer unit
The vehicle dwell time of identity A is longer, reaches the requirement of time period t, therefore the vehicle of identity A is determined as parking vehicle, analysis
The vehicle of identity A is earliest 15 by the time that rfid device recognizes:00, and 15:The seizure condition of 00 or so No. 1 parking stall
Changed, illustrates the stoppage of vehicle of identity A No. 1 parking stall.It should be noted that those skilled in the art state on the implementation
Specific implementation mode when, be not limited with above-mentioned example.
In more embodiments, multiple parking stalls may have the case where vehicle is prepared to stop simultaneously, thus have
The seizure condition for being likely to occur multiple parking stalls changes, in order to distinguish the parking stall position of different identity parking vehicle, Ke Yitong
The RSSI value for the different vehicle electron identifyings for judging that rfid device receives is crossed to judge the position of vehicle.Automotive electronics mark
Know the activation password for receiving rfid device, the relevant information of vehicle in vehicle electron identifying is sent by radiofrequency signal
To rfid device, the distance due to different vehicle electron identifyings from rfid device, the decaying of radiofrequency signal
It is different, therefore can be by judging that RSSI value can be obtained by the distance of relative distance, the bigger vehicle of RSSI value is known from radio frequency
Other device is closer.Preferably, control device identifies that the size of received signal strength indicator value determines not according to rfid device
Stop with the front and back position of identity parking vehicle, and according to the changed parking stall front and back position correspondence determination of seizure condition
The parking stall position that vehicle vehicle specifically stops.It should be added that the above embodiment can also pass through above-mentioned time period t
It is required that constraint judges whether the specific identity parking stall that rfid device is identified is parking vehicle.
For example, being respectively No. 1 parking stall, No. 2 parking stalls there are two parking stalls, it is assumed that the parking stall of No. 1 parking stall than No. 2 is from radio frequency identification
Device is close, this partial information has been preset in control device, and control device can inquire between parking stall and parking stall at any time
Relative position relation, it is preferable that number order as described above is determined according to a distance from rfid device.When No. 1 parking stall,
No. 2 parking stalls have vehicle to stop respectively, at this moment the seizure condition that detects of parking stall device for detecting occupation of No. 1 parking stall, No. 2 parking stalls
Being changed, rfid device also detects that the parking vehicle of two different identities, respectively A identity, B identity, if
Correspondence can not be found only by variation relation, i.e., does not know that the parking vehicle of A identity still exists No. 1 parking stall
The parking vehicle of No. 2 parking stalls, B identity is not also known similarly.It at this moment can be by the RSSI that is received according to rfid device
Value determines two relative distances of the different identity vehicle from rfid device, specifically, the parking vehicle ratio B bodies of A identity
The parking vehicle of part is close from rfid device.Correspondence can be analyzed from above-mentioned condition, because of the parking vehicle of A identity
It is nearest from rfid device, while No. 1 parking stall is nearest from rfid device, it is possible to determine the parking vehicle of A identity
It is parked in No. 1 parking stall, and the parking vehicle of B identity is parked in No. 2 parking stalls.
As shown in figure 5, parking of automobile management method in an embodiment of the present invention, includes the following steps：
S1, detect whether specific parking stall has parking vehicle occupancy by the parking stall device for detecting occupation on each parking stall；It is logical
