Problems solved by technology
Due to the adoption of the above two technologies, the traditional indoor location navigation system has obvious defects in use scenarios. One is that the indoor (especially in the basement) GPS signal is weak or absent, and the longitude and latitude information of the object cannot be accurately positioned; the other is The WIFI access point has high power consumption and limited coverage, and large-scale deployment wastes energy, which runs counter to energy conservation and emission reduction, and a green earth; the third is that the current indoor positioning accuracy is not enough to achieve accurate positioning and navigation
All of the above limit the widespread use of traditional indoor location navigation systems, and also seriously affect the actual experience of users during use

Embodiment
[0062] In this embodiment, the real-time positioning of the position of the driving car in the underground parking lot environment is used as an example. The car is equipped with a vehicle-mounted Bluetooth module. This Bluetooth module supports Bluetooth 5.1 and above standards. The bluetooth module communicates, and the location positioning device of the underground parking lot obtains the mac address information of the vehicle-mounted bluetooth module of the car, and registers and saves it.
[0063] as attached figure 1 As shown, it is a composition diagram of the indoor object position real-time positioning system of the present invention, that is, the underground parking lot position positioning device of the present embodiment:
[0064] Wherein, 101 refers to a fixed-position Bluetooth positioning node device, and the coordinate position information of the 101 device is configured and saved by the 301 position positioning device, and the Bluetooth positioning node device...

The invention relates to the field of positioning and navigation, in particular to a system and a method for positioning a position of an indoor object in real time, which are capable of realizing high-precision positioning of an indoor object with a Bluetooth module under the condition that an indoor GPS signal is weak or no GPS signal exists. The system for positioning the position of the indoorobject in real time comprises Bluetooth positioning node devices and a position positioning device, wherein the Bluetooth positioning node devices are distributed indoors, and the Bluetooth positioning node devices are in wireless connection with the position positioning device; the Bluetooth positioning node devices are used for carrying out real-time distance measurement on the object in measurement ranges of the Bluetooth positioning node devices and reporting measured distance position information to the position positioning device; and the position positioning device adopts a multipointdistance matrix for positioning according to the distance position information and mac address information of a Bluetooth module of a to-be-positioned object, and calculates the real-time position information of the indoor to-be-positioned object. The system and the method are suitable for high-precision positioning of the indoor object with the Bluetooth module.
Description
technical field [0001] The invention relates to the field of positioning and navigation, in particular to a system and method for real-time positioning of indoor object positions. Background technique [0002] Indoor location navigation systems are widely used in people's daily travel activities. Traditional indoor location navigation systems are mainly realized by GPS positioning and navigation technology plus WIFI-assisted positioning and navigation technology. GPS positioning and navigation technology can obtain the location of objects The longitude and latitude information, its location accuracy is between ten meters and one hundred meters, and the location accuracy of the WIFI access point for the surrounding WIFI access devices can reach the meter level. Due to the adoption of the above two technologies, the traditional indoor location navigation system has obvious defects in use scenarios. One is that the indoor (especially in the basement) GPS signal is weak or absen...
