Bluetooth networking based positioning system

Abstract

The invention discloses a Bluetooth networking based positioning system. The Bluetooth networking based positioning system comprises an intelligent terminal with a Bluetooth module, a Bluetooth gateway, a cloud end monitoring center and multiple Bluetooth tubes; the Bluetooth tubes are distributed in a target area; the intelligent terminal is in communication connection with the Bluetooth tubes; the Bluetooth tubes are in communication connection with the Bluetooth gateway; and the Bluetooth gateway is in communication connection with the cloud end monitoring center. The Bluetooth networking based positioning system has a big network capability, high monitoring density and wide range; as access to a cloud end by utilizing a matured and steady public wireless network is realized in a Bluetooth module based communication way, the Bluetooth networking based positioning system can cross big physical space, can enlarge the covered monitoring area, can reduce the dead zone and is suitable for relatively dispersive distribution points with relatively far distances.

Description

technical field [0001] The invention relates to a positioning system based on bluetooth networking, and belongs to the application field of the Internet of Things. Background technique [0002] With the increase of personal vehicles, it is now a big problem to find cars in the reverse direction. Sometimes you can’t find a parking spot after turning around a few times. Some shopping malls and communities have underground parking lots, which increases a lot of parking spaces. But some friends are reluctant to park their cars in the underground parking lot. The reason is that they are not familiar with the parking rules of the parking lot at the address. It is difficult to find a car when parking. This has become one of the common problems encountered in life. How to efficiently find a car in reverse, through real-time monitoring and effective positioning control measures, can effectively solve the problem of parking and finding a car. [0003] The existing positioning measure...

AI Technical Summary

Problems solved by technology

The overall positioning accuracy of ultrasonic positioning is high, and the structure is simple, but ultrasonic is greatly affected by multipath effects and non-line-of-sight propagation, and requires a large amount of investment in underlying hardware facilities, and the cost is too high; WIFI is applied to small-scale indoor positioning, and the cost is relatively high. Low, but whether it is used for indoor or outdoor positioning, the Wi-Fi transceiver can only cover an area within a radius of 90 meters, and is easily interfered by other signals, thereby affecting its accuracy, and the energy consumption of the locator is also high ; ZigBee positioning determines the location of the object by measuring the distance from the object to multiple reference nodes with known locations. The positioning accuracy is low, and it is not common in practical applications.
