Description
Technical field
The present invention system is about a kind of wireless network signal gathering system, be meant a kind of record GPS locating information, 802.11 signals, mobile communication network base station information detected especially, and can collect and verification system the wireless network signal that gather data carry out demonstration validation, institute's gathered data can be used for the calculation of assisted location method.
Background technology
Mobile positioning technique mainly contains at present: three kinds of modes such as GPS/A-GPS, base station location, Wi-Fi location.Wherein the GPS/A-GPS location is the most accurate, and error can be within 15～20 meters scopes, still because indoor veil can receive the gps satellite signal by obstruction equipment, so be not suitable for indoor positioning; Base station location, though be not subject to indoorly, error range is bigger, sometimes even nearly about one kilometer, navigates and path planning so be suitable for.The error range of Wi-Fi location is between between the two, and is not subject to the indoor and outdoor, therefore is considered to be the alternative of GPS/A-GPS location.
In the at present known Wi-Fi wireless location method, localization method and system that Taiwan patent application case 200928416 proposes, to (Pattern Matching),, be divided into training, two stages of location based on aspect ratio with reference to the system architecture of RADAR location algorithm.In the training stage, elder generation on the position of a plurality of sampling points, collects wireless network signal data respectively; Then, from gather information, the corresponding relation of acquisition sampling point position and signal feature is divided into a plurality of groups, sets up a locator data storehouse.When positioning stage, it is right to see through aspect ratio, finds out the group the most similar to anchor point, again according to the characteristic in the group, calculates the possible position of anchor point.This kind localization method need be dependent on training data enough and that be evenly distributed, the error range that can effectively reduce the location.In case number of sampling is not enough, or skewness, will have a strong impact on positioning result.In indoor environment, than being easier to satisfy such training requirement.But problem is, when moving on to large-scale outdoor environment, collect the sample data of enough scales, and manpower that is spent and time cost just become very huge.In the training stage, finish the collection operation how rapidly, effectively, this is a problem that is worth further investigation.
Taiwan patent application case 200828880 propose a kind of under wireless environment the novel sampling location determination method in the navigation system.Its objective is that hope can effectively reduce the number of actual sampling point in the training stage.The uncertainty that the probability of the wireless signal signal strength signal intensity of this methods analyst sampling point is distributed, and and neighbor point its diversity factor relatively, whether be novel sampling location to determine this position.In order to determine suitable sampling point, this method requires and must measure the stability of wireless signal earlier on all positions of the actual area that wireless system operates, could recommend suitable novel sampling location according to the environmental aspect of reality then.Though this method is applicable to the narrow interior space, if be used for outdoor environment, it is very big that the burden of human cost just becomes.This shows, when collecting sample,, be difficult to apply mechanically fully out of doors in the environment at the used gathering method of the interior space in the training stage.
U.S. patent application case US2006/0095349 proposes a kind of method of setting up location database.It sees through car-mounted device and collects Wi-Fi signal and gps coordinate, utilizes routine plan driving path, when collecting, and the anti-possible position that pushes away Wi-Fi wireless access point (Access Point) of real-time operation, and deposit in the remote data base.If will accurately extrapolate the possible position of wireless access point, car must detour a week at least at this access point external road.But at large-scale metropolitan area, require each block all to detour a week, will certainly repeat through many streets, therefore this method utilizes POSTMEN OF CHINA route (Chinese postmanrouting) algorithm to plan the driving path, reduce the street of repeating process, reduce unnecessary human cost as far as possible.The prerequisite of POSTMEN OF CHINA route algorithm is, the driving path is the street of checkerboard, and this point meets the street layout in the most cities of the U.S., but not exclusively is applicable to the city street in Taiwan.In the city, Taiwan, irregular sinuous road is arranged more, the complicated often again alleyway of the block between main road lane, the path planning of POSTMEN OF CHINA route all is difficult to be suitable for these situations.Secondly,, only use the car-mounted device gather data, can't contain All Ranges sometimes because the alleyway lane in Taiwan is a lot of.During the design gathering system, should try one's best to be installed on different types of equipment, so that be applicable to various environmental demand.
Although the Wi-Fi localization method of prior art is existing multiple, how in the training stage, collect enough sample datas quickly and effectively, the research of this respect is still rare at present.Yet the distributed degrees of sample number but is the important key that influences Wi-Fi position error scope.Especially when outdoor location,, need the huge cost of labor of cost in order to collect the sample data of enough scales.This shows that the above-mentioned mode of commonly using still has many disappearances, real non-one kindhearted design, and demand urgently being improved.
In view of this, the invention provides a kind of wireless network signal and collect and verification system, it can simplify the overall operation flow process, the operating efficiency when lifting Wi-Fi is positioned at the training stage.
