The system is mainly technically characterized in that each parking space is provided with wireless landmark nodes and a vehicle-mounted tag; each wireless landmark node sends the identification information of the node to the vehicle-mounted tag on a vehicle in a broadcast mode according to preset transmission power; and the vehicle-mounted tag sends the received identification information of a number of landmark nodes and signal intensity to the parking lot server through the parking space information collector. According to the utility model, the design is reasonable; the vehicle-mounted tag is arranged on the vehicle to be parked; a number of wireless landmark nodes with known physical positions are arranged in parking spaces; through the transmission power and the communication radius of the wireless landmark nodes, the problems of poor parking positioning accuracy and high cost, which are caused by environmental interference, of a roadside parking lot are solved; and the parking positioning accuracy of the roadside parking lot is improved.
Description
Technical field
The utility model belongs to vehicle positioning technology field, parking lot, especially a kind of parking lay-by parking positioning system.
Background technology
The subject matter that parking lay-by Vehicle positioning system will solve is: obtain a known vehicle and be parked in the information on which parking stall in current parking lot.Obtain this informational needs and realize following three functions: obtain target parking position block physical location, obtain target vehicle dead ship condition, obtain the unique identification of target vehicle.
Realize above parking lay-by vehicle parking positioning function and have two large difficult points: one, open work, can not adopt parking garage conventional method (as on each parking stall, camera being installed, the vehicle license plate number of this parking stall of taking pictures) to carry out car plate identification and solve the problem which parking stall is known vehicle be parked in; Two, external environmental interference is large, and uncontrollable factor is many, causes open parking ground parking stall measure error amount large.
One of existing solution is: geomagnetic parking stall detector is installed on each parking stall and on each car, vahicles label is installed.Vahicles label sends the information with unique ID number with the continuous peripherad geomagnetic parking stall detector of mode of broadcast, RSSI value receiver module is installed in each geomagnetic parking stall detector, when detecting vehicle, geomagnetic parking stall detector enters behind current parking stall, parking space detector is opened receiving port and is received ID information and the RSSI signal intensity that label sends, and No. ID, RSSI value are crossed to parking space information receiver together with parking stall measure information exchange and be uploaded to parking lot server, realize thus parking lay-by vehicle location function.This scheme weak point is: the temperature influence of (1) geomagnetic sensor own is larger, its reading under same place, similarity condition can change a lot because of the difference of ambient temperature, while particularly using under condition out of doors, be very easy to Yin Wendu reason and produce error detection; For example, in most of city of northern China, the maximum temperature difference of winter and summer will be more than 60 degree, if detecting device is arranged on summer in winter, when summer is during winter approached, the accuracy of detecting device can be greatly affected so; Even within same season, day and night temperature also can be greater than 20 degree sometimes, can have influence on equally the normal work of geomagnetic parking stall detector.(2) geomagnetic sensor is arranged under open-air atmosphere, is easily magnetized, once geomagnetism detecting is made mistakes, the corresponding relation of vahicles label and parking stall must be made mistakes, and will occur undetected or flase drop situation.In order to prevent undetected or flase drop, also usually adopt the method for correction at zero point, when occurring that environmental interference causes erroneous judgement disconnected, re-start Zero calibration, in order to upgrade reference value.Although above Zero calibration method is feasible, in actual mechanical process, maintenance is large, and implementation cost is high.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
A parking lay-by parking positioning system, as shown in Figure 1, comprise the self identification information that is built-in with of installing on each parking stall wireless terrestrial reference node, be arranged on vahicles label, parking space information gatherer and parking lot server on vehicle; A plurality of wireless terrestrial reference nodes send self identification information in the mode of broadcasting to the vahicles label on vehicle according to default emissive power, vahicles label is uploaded to parking lot server by the self identification information of a plurality of terrestrial reference nodes that receive and signal intensity by parking space information gatherer, thereby realizes parking lay-by vehicle location function.In native system, wireless terrestrial reference node select is arranged on four drift angle places on each parking stall, and as shown in Figure 1, this parking lot is distributed with the wireless terrestrial reference node of upper and lower two row, the parking situation of the corresponding a kind of direction of terrestrial reference node that every row is wireless.Consider two kinds of parking directions in parking lot, therefore, in each direction, be laid with corresponding wireless terrestrial reference node, specific to each parking stall, have two rows node, two wireless terrestrial reference node correspondences on same broadside line detect towards the parking of this terrestrial reference node parking direction.
As shown in Figure 2, wireless terrestrial reference node comprises MCU, power module, wireless radio frequency modules and antenna; This power module is connected with MCU, wireless radio frequency modules respectively for its power supply, and this MCU is connected with wireless radio frequency modules, stores the terrestrial reference node ID number of binding with block, terrestrial reference node place coordinate information in MCU.
