Abstract
The utility model discloses a parking stall detecting system used for a parking lot. The middle part of a left line and the middle part of a right line of a parking stall are provided with an activation unit each. The activation units transmit activation signals including address codes of the activation units wirelessly in a first frequency band. Vehicle electronic labels entered into an activation signal range transmit a piece of vehicle positioning data wireless in a second frequency band every two label working periods based on activation unit address codes obtained through analyzing the activation signals and field intensity of the activation signals. A reader transmits the vehicle position data to a data server. The data server determines vehicle label location based on vehicle electronic label identification codes, the activation unit address codes and field intensity of the corresponding activation signals in the vehicle positioning data. And if the vehicle label position does not change in a period of time, a parking status is determined, so that whether parking stalls are occupied or not can be judged accurately and identities of vehicles in the occupied parking stalls can be determined. The utility model also discloses the electronic labels.
Description
Technical field
The utility model relates to the network information and digital sensing technology, particularly a kind of parking position detection system and electronic tag.
Background technology
Along with the develop rapidly of automobile industry, the problem that it is difficult to park in city is more and more outstanding, improves parking facility, and collection and shared each parking position take the real-time information with parking spot, and raising is parked extremely urgent with the efficiency of picking up the car.At present, most of parking lot Dou Shiyou parking lot staff is to parking stall partition management, and such parking lot management mode place produces following problem:
1. in city region, some parking lots may Occupied, but car owner enters this parking lot because learning in advance the parking stall situation in this parking lot, not only cannot stop, but also can cause the problems such as this parking lot passage blocks up, air ambient is severe; Meanwhile, may there are a large amount of vacant parking stalls in some parking lots, and car owner does not enter this parking lot because learning in advance the parking stall situation in this parking lot, causes this parking position idle, makes this parking turnover rate low.
2. when car owner returns to parking lot and picks up the car, due to inner part of parking lot situation more complicated, or while forgeing the parking spot of own vehicle, car owner is often difficult to quick and precisely find own vehicle, causes time waste.
Chinese patent application 201110438363.X discloses a kind of parking position detection system, as shown in Figure 1 and Figure 2, comprises electronic tag 10, watch-dog 20, data sink 30Ji data center 40.Electronic tag 10 is in order to store the information of car owner and vehicle, and each electronic tag 10 is arranged on a vehicle.Watch-dog 20 is arranged on the parking stall 200 in parking lot, and a watch-dog 20 is at least set respectively on each parking stall 200.Each watch-dog 20 rests against the electronic tag 10 of the vehicle on its corresponding parking stall 200 in order to monitoring, and according to the situation of the electronic tag 10 monitoring, records parking information as the status information on berthing time, time departure, parking duration and parking stall.When watch-dog 20 recognizes an electronic tag 10 in parking stall 200, record recognizes the time of this electronic tag 10, the time that vehicle of these electronic tag 10 correspondences is stopped, records this parking stall 200 in taking simultaneously.Correspondingly, when watch-dog 20, on parking stall, 200 interior None-identifieds arrive this electronic tag 10, record None-identified to the time of this electronic tag 10, the vehicle of these electronic tag 10 correspondences leaves the time on this parking stall 200, records this parking stall 200 in the free time simultaneously.In addition, watch-dog 20 also obtains according to berthing time and time departure the duration that stops.This watch-dog 20 all has communication and routing function, can automatically form monitor network by data sink 30Yu data center 40, and above-mentioned information is sent to data center 40 in real time, thereby realize the real-time monitoring to each parking stall 200.This data sink 30 receives above-mentioned parking information and parking stall status informations, and above-mentioned information exchange is crossed to existing communication network is sent to data center 40 as GPRS, 3G or Ethernet etc.Data center 40 comprises database 41, parking stall administrative unit 42 and wireless communication unit 43.Parking information and parking stall status information that these database 41 storage data sinks 30 send.Meanwhile, this database 41 is also stored the expenses standard information on parking stall 200.This parking stall administrative unit 42 comprises parking stall predetermined module 421, parking stall enquiry module 422 and parking stall expense enquiry module 423.The parking stall predetermined request that this parking stall predetermined module 421 sends by mobile terminal in order to receive car owner, and process corresponding predetermined request.If the predetermined parking stall 200 of specifying of car owner, parking stall predetermined module 421 is obtained the current state on the appointment parking stall 200 of storing in database 41, as in taking, in modes such as language, note or mails, notify car owner parking stall to be scheduled to unsuccessfully, car owner can resend parking stall predetermined request information, is scheduled to other parking stall 200;
