The position, parking stall that the parking vehicle identity change corresponding relation determination parking vehicle that control device 23 changes according to the seizure condition of all parking stalls, rfid device 22 identifies specifically stops.Such as, parking area comprises No. 1 parking stall, No. 2 parking stalls ... wherein No. 2 parking stalls are detected by parking stall device for detecting occupation 21 and parking stall stop there is vehicle, rfid device 22 is also by having parking vehicle in radio-frequency signal detection to parking area, and obtain the identity of this parking vehicle, because now parking stall device for detecting occupation 21 and rfid device 22 detect based on objective fact be the same, that is detected by the parking stall device for detecting occupation 21 of No. 2 parking stalls parks cars, also be parking cars of detecting of video identification device 22, certainly exist corresponding relation, the identity of the testing vehicle register that rfid device 22 detects necessarily No. 2 parking stall parking vehicles.Just can be drawn by binding like this, the position, parking stall that parking vehicle specifically stops, timing is started by message accounting, after detecting that vehicle leaves parking stall by parking stall device for detecting occupation, calculate the Parking Fee of specifying identity vehicle, the car owner of such respective identity vehicle just can pass through bank or other commission merchant's payings, facilitates payment management, improves the efficiency of parking management.
You need to add is that, parking stall device for detecting occupation 21 specifically includes but not limited to geomagnetic sensor, ultrasonic detection device, ground induction coil pick-up unit, video detecting device etc., they realize detecting whether parking stall have a car functionally respectively have relative merits.
Geomagnetic sensor is a kind of acquisition terminal utilizing earth induction principle inspection vehicle bit stealing state, according to the GEOMAGNETIC CHANGE situation detected on parking stall, realizes parking stall judges with presence or absence of vehicle.Preferably, geomagnetic sensor is earth magnetism ball.In order to prevent the erroneous judgement of metal interference to geomagnetic sensor, geomagnetic sensor can comprise the earth magnetism ball being embedded in the multiple key point in parking stall and the earth magnetism receiver be connected with multiple earth magnetism ball, and whether earth magnetism receiver has storing cycle according on the testing result comprehensive descision parking stall of multiple earth magnetism ball.
The principle of work that ultrasonic detection device adopts utilizes ultrasound wave to launch, and measures tested distance, thus judge whether parking stall has vehicle to take by the time difference after the transmitting of tested vehicle, echo reception.If the distance surveyed and other parameters reach initialize data, then judge that there is vehicle parking stall.
Ground induction coil pick-up unit is the ground induction coil comprising two to three circle wires imbedding earth's surface, and the oscillatory circuit cooperatively to form with electric capacity, when parking stall there being the vehicle of parking, space medium changes and causes the change of oscillation frequency, by this change to judge on parking stall vehicle with or without.
Video detecting device captures parking stall image by camera, utilizes image processing algorithm in the image of parking stall, arrange virtual region, parking stall, if analyze the image information having vehicle in virtual region, parking stall, then judges that there is parking vehicle parking stall.
As shown in Figure 2, parking of automobile management system module figure in an embodiment of the present invention, geomagnetic sensor is installed in each parking stall, in parking area front portion, rfid device 22 is set, they communicate with control device 23 respectively, geomagnetic sensor is responsible for the seizure condition detecting parking stall, and rfid device 22 is responsible for the identity identifying parking vehicle.
As shown in Figure 3, parking of automobile management system module figure in the another embodiment of the present invention, ultrasonic detection device is installed in each parking stall, in parking area front portion, rfid device 22 is set, they communicate with control device 23 respectively, ultrasonic detection device is responsible for the seizure condition detecting parking stall, and rfid device 22 is responsible for the identity identifying parking vehicle.
As mentioned above, geomagnetic sensor, ultrasonic detection device, ground induction coil pick-up unit, video detecting device are all the detections adopting different principle to realize parking stall seizure condition, but due to respective feature, there is again the possibility being subject to external interference, therefore any one is adopted separately all likely to occur the possibility judged by accident, in order to improve the accuracy that parking stall seizure condition detects, can combine between said apparatus, making up mutually respective defect.As shown in Figure 4, parking of automobile management system module figure in another embodiment of the present invention, the parking stall device for detecting occupation 21 that each parking stall is installed comprises ultrasonic detection device and geomagnetic sensor.Show that parking stall seizure condition can be more accurate by the testing result both comprehensively analyzing, such as, only have when ultrasonic detection device and geomagnetic sensor have all detected that vehicle could be determined there is storing cycle parking stall.
It should be noted that, the concrete array mode of parking stall device for detecting occupation 21 is not described as limit with above-mentioned, those skilled in the art are on the basis of the embodiment of above-mentioned record, it will also be appreciated that other array mode, such as, utilize the testing result of geomagnetic sensor, ultrasonic detection device, ground induction coil pick-up unit, video detecting device comprehensively to analyze parking stall seizure condition or can realize cooperating comprehensive analysis together with device that parking stall takies measuring ability with other.
As mentioned above, the border of parking area is fuzzy, and occur that the one of the main reasons of this situation is, rfid device overlay area is determined by radio frequency beam width, and beam angle can be subject to the environmental impact such as external temperature, weather fluctuates up and down.When applying with Roadside Parking environment, the testing vehicle register that rfid device may recognize not only comprises the parking vehicle identity on parking stall, also may comprise testing vehicle register passing on the road of side, parking stall, so just likely occur only having the seizure condition of a parking stall to change, and rfid device has recognized the vehicle of more than two different identity, the vehicle that corresponding relation can not be found to determine parking stall is being parked like this has been which identity vehicle concrete.
In order to overcome above-mentioned defect, preferably, control device has changed in time period t according to the seizure condition of specific parking stall, and the vehicle of the same identity that rfid device recognizes always is defined as parking vehicle.It is to be appreciated that vehicle passing on road to affect the change that parking stall device for detecting occupation detects parking stall seizure condition, the time of vehicular traffic in parking area is of short duration simultaneously.Therefore, only have on a parking stall and have vehicle when stopping, seizure condition on this parking stall changes, from at the moment in time period t, rfid device constantly can recognize the identity of this automobile, but the situation that the identity of the vehicular traffic also do not got rid of on road is also identified, but vehicular traffic is because can leave parking area at short notice, so rfid device can recognize this identity vehicle in the portion of time in time period t, and after vehicle leaves parking area, rfid device would not recognize the identity of vehicular traffic.Therefore, recognized by rfid device by analyzing the vehicle of which identity in time period t, the vehicle of this identity is exactly parking vehicle always.
Time period t determines according to the vehicle flowrate of parking area, and in the present embodiment, parking area is on road, so namely by present road vehicle flowrate situation arrange, when vehicle flowrate is larger, can thinks and pass by one's way Vehicle Speed comparatively slowly, the value of time period t can arrange greatly a bit; When vehicle flowrate is less, vehicle of passing by one's way can not stop too of a specified duration at parking area, therefore can the value of time period t be arranged a little bit smaller.In addition, in the management of parking charge in each city, there is the regulation of an initial chargeable time, namely parking vehicle starts not collect the charges in the set time in parking, as being can the regulation of Free parking in 15 minutes, just started charging more than 15 minutes, the vehicle only stopped 15 minutes carries out parking management and there is not any meaning to a certain extent.Therefore, time period t also can determine according to initial chargeable time.
In concrete embodiment, can adopt and buffer unit is set in control device, for storing vehicle and the recognition time of all identity of rfid device identification as vehicle electron identifying information pool, if the vehicle of the specific identity stored in buffer unit have left parking area, namely, when rfid device can not recognize the vehicle of this identity, the identification record of this identity vehicle all about in buffer unit is deleted.Control device can analyze the relevant information in vehicle electron identifying information pool (i.e. buffer unit), the time changed from the seizure condition of parking stall lights, the vehicle registration information of lasting same identity whether is had in time period t, such as, the time that parking space state changes is 14:00, time period t is set to 5 minutes, can inquire about in vehicle electron identifying information pool, whether 14:00,14:01,14:02,14:03,14:04,14:05 have the vehicle of a certain specific identity, and the time interval also can adjust according to actual needs.
Buffer unit also can adopt memory space larger, the storer that storage speed is fast, preferably, control device is arranged in the server of rear end, all records that radio frequency recognition device recognizes are preserved, also preserve each parking stall seizure condition information and seizure condition transformation period dot information simultaneously, control device is by analyzing the data of the rfid device identification of preserving in buffer unit, draw the testing vehicle register stopping overtime section t in parking area, then them are analyzed first by time that rfid device recognizes, then find and there occurs change with the seizure condition of which specific parking stall of this time correlation, thus find the position, parking stall that corresponding relation determination parking vehicle specifically stops.Such as, analyze in buffer unit and show that the vehicle dwell time of identity A is longer, reach the requirement of time period t, therefore the vehicle of identity A is defined as parking vehicle, the vehicle analyzing identity A is 15:00 by the time that rfid device recognizes the earliest, and the seizure condition of about 15:00 No. 1 parking stall there occurs change, illustrate that the stoppage of vehicle of identity A is No. 1 parking stall.It should be noted that, during the embodiment that those skilled in the art state on the implementation, be not limited with above-mentioned example.
In more embodiment, multiple parking stall may have the situation that vehicle is prepared to stop simultaneously, so just likely occur that the seizure condition of multiple parking stall changes, in order to distinguish the position, parking stall of different identity parking vehicle, can by judging that the RSSI value of the different vehicle electron identifying that rfid device receives judges the position of vehicle.Vehicle electron identifying receives the activation password of rfid device, by radiofrequency signal, the relevant information of vehicle in vehicle electron identifying is sent to rfid device, because different vehicle electron identifying is from the distance of rfid device, the decay of radiofrequency signal is also different, therefore can by judging that RSSI value just can obtain the distance of relative distance, the larger vehicle of RSSI value from rfid device more close to.Preferably, control device according to the front and back position of the size determination different identity parking vehicle of rfid device identification received signal strength indicator value, and according to the position, parking stall that the parking stall front and back position corresponding relation determination parking vehicle changed with seizure condition specifically stops.It should be added that, by the requirement constraint of above-mentioned time period t, above-mentioned embodiment also can judge whether the specific identity parking stall that rfid device identifies is parking vehicle.
Such as, there are two parking stalls and be respectively No. 1 parking stall, No. 2 parking stalls, suppose No. 1 parking stall than No. 2 parking stalls close to rfid device, this part information has been preset in control device, control device can inquire the relative position relation between parking stall and parking stall at any time, preferably, number order as above determines according to the distance from rfid device.When there is vehicle No. 1 parking stall, No. 2 parking stalls respectively in parking, at this moment the seizure condition that the parking stall device for detecting occupation of No. 1 parking stall, No. 2 parking stalls detects there occurs change, rfid device also detects the parking vehicle of two different identity, be respectively A identity, B identity, corresponding relation can not be found iff by variation relation, namely do not know the parking vehicle of A identity No. 1 parking stall still No. 2 parking stalls, the parking vehicle of B identity is not in like manner known yet.At this moment can be determined the relative distance of two different identity vehicles from rfid device by the RSSI value received according to rfid device, particularly, the parking vehicle of A identity than the parking vehicle of B identity close to rfid device.Corresponding relation can be analyzed from above-mentioned condition, because the parking vehicle of A identity is nearest from rfid device, No. 1 parking stall is nearest from rfid device simultaneously, so can determine that the parking vehicle of A identity 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, comprises the following steps:
S1, detect specific parking stall by the parking stall device for detecting occupation on each parking stall and whether have parking vehicle to take; Can obtain there is parking vehicle in which parking stall by step S1, can also determine to stop in which parking stall by seizure condition change.Parking stall device for detecting occupation can comprise at least one in geomagnetic sensor, ultrasonic detection device, ground induction coil pick-up unit, video detecting device, and embodiment can with reference to the embodiment of parking of automobile management system.
S2, detected the identity of parking vehicle in parking area by the rfid device of parking area front portion; The identity of parking vehicle in parking area can be obtained by step S2.Because the vehicle completing parking has been bound with specific parking stall, so by getting rid of the parking vehicle identity can determining to stop.Rfid device is preferably super high frequency radio frequency recognition device, and the passive vehicle electron identifying coordinated with it is arranged on the front windshield of vehicle.
S3, the position, parking stall of specifically stopping according to the parking vehicle identity that seizure condition changes, described rfid device the identifies change corresponding relation determination parking vehicle of all parking stalls.In order to ensure parking management exactly, reduce the interference of vehicular traffic, changed in time period t according to the seizure condition of specific parking stall, the vehicle of the same identity that rfid device recognizes always is defined as parking vehicle.Time period t determines according to the vehicle flowrate of parking area or initial chargeable time.If there is the seizure condition of two or more parking stall to change simultaneously, according to the front and back position of the size determination different identity parking vehicle of rfid device identification received signal strength indicator value, and according to the position, parking stall that the parking stall front and back position corresponding relation determination parking vehicle that seizure condition changes specifically stops.Concrete embodiment can with reference to the embodiment of parking of automobile management system.
It should be noted that, the order of step S1 and step S2 is not specific, and step S1 and step S2 under normal circumstances, can carry out simultaneously.But also can detect that the seizure condition of certain parking stall starts step S2 when changing again in step sl.Or the remote identification characteristic based on rfid device in step S2 first recognizes the identity of vehicle, then step S1 just detects that the seizure condition of certain parking stall changes.Step S1 to step S3 is that circulation is carried out in practice, thus realizes the whole day unmanned management of parking of automobile.
