Abstract

The invention discloses a real-time data mining positioning method combining GIS road network and bluetooth beacon, comprising the following steps: step 1, record beacon historical positioning data, and receive personnel beacon data; step 2, obtain positioning through real-time positioning data The location probability of the possible area of ​​personnel; step 3, the GIS spatial data storage and calculation module performs road network overlap calculation according to the location probability of the possible area of ​​personnel, and obtains the probability of the possible area of ​​personnel after filtering; The data is judged and the real-time location data is determined. Step 5. Use DTW and the range of the road network and the possible range of positioning to predict the possible position in the future time; by using this method, the accuracy of the positioning method is relatively high, and the positioning problem can be converted into For probability problems, using long-term series data for correction can prevent large anomalies in positioning.

Description

technical field [0001] The invention relates to the technical field of personnel positioning, in particular to a method for real-time data mining and positioning combined with GIS road network and bluetooth beacons. Background technique [0002] Bluetooth positioning is based on the RSSII (Received Signal Strength Indication, signal field strength indication) value, and positioning is performed through the principle of triangulation. There are many mature business applications in the fields of elderly care positioning, substation personnel positioning, chemical plant personnel positioning, and construction site personnel positioning. The existing Bluetooth beacons send broadcasts continuously. , and send relevant bluetooth information to the server to calculate the positioning method. Combine the obtained personnel positioning data with the map to complete the management of personnel positioning. However, since the accuracy of Bluetooth beacons is usually 2-5 meters, in pra...
