Space positioning system and method based on intelligent lamp post

Abstract

The invention discloses a space positioning system and method based on an intelligent lamp post, and relates to the technical field of city positioning application, the system comprises a positioningmanagement platform, aggregation positioning nodes and auxiliary positioning nodes, and the system adopts a dense city lamp post as a positioning node carrier; step-by-step automatic background calibration of the city lamp post position is completed by a node Bluetooth high-precision positioning technology and automatic information interaction between positioning nodes; and on the other hand, thenodes after automatic position calibration are adopted to monitor a Bluetooth signal of the nearby city moving target carrying the Bluetooth terminal for centimeter-level rapid positioning and tracking of the city target position. The city positioning management platform can accurately track and position the city moving target carrying the Bluetooth device by means of the network, and compared with GPS positioning, the positioning speed is higher, and more energy is saved.

Description

technical field [0001] The invention relates to the technical field of urban positioning applications, in particular to a space positioning system and method based on smart light poles. Background technique [0002] At present, GPS and AGPS are mostly used for urban road target positioning to obtain the latitude and longitude information of the target and present it on the map. This method can locate urban moving targets with meter-level accuracy. [0003] Light poles are the basic equipment of urban roads. Their geographical location and uniform distribution can be used as a carrier for city-assisted positioning. By identifying the geographical specific location information of each light pole on the map and then communicating with the designated light pole to determine the target the position of the object. [0004] Patent No. CN02112612.7, which is relatively similar to the present invention, proposes a Bluetooth-based geographic positioning technology and device. This po...

Problems solved by technology

This positioning method can only accurately position the target object between the rod and the rod, and cannot achieve the purpose of precise positioning

[0005] Patent No. CN201120503359.2, which is relatively similar to the present invention, discloses a street light pole GPS geographic positioning system, that is, a GPS signal receiving and processing device is installed on the pole body of the street light pole, and the position of the pole body is located by GPS to locate the position on the pole body at the designated position. The lighting device is managed and controlled, but this method still has the problem of positioning accuracy of the rod body

[0006] In addition, in the existing technology, the position information entry method of the pole body is generally that the operation and maintenance personnel go to each light pole position to obtain the rough position information of the pole body through smart auxiliary equipment such as mobile phones, and then artificially adjust the position on the map to ensure the position. The accuracy of this input method is low and error-prone
