Abstract

The invention relates to the communication field, and discloses a Bluetooth-based positioning method and a device thereof. The positioning method of the present invention includes the following steps: the mobile terminal receives the Bluetooth signal transmitted by at least one Bluetooth beacon device; obtains the MAC addresses of each Bluetooth beacon device according to the received Bluetooth signal, and selects each Bluetooth signal whose MAC address is the first MAC address. The Bluetooth beacon device is used as a reference device; the Bluetooth signal strength of each reference device and the broadcasted beacon identifier are acquired; and the position of the mobile terminal is calculated according to the acquired Bluetooth signal strength of each reference device and the broadcasted beacon identifier. The present invention sets all bluetooth beacon devices to the same MAC address, and the MAC addresses of other normal bluetooth devices are different from these bluetooth beacon devices, so the identification of the MAC address can effectively eliminate the interference of other bluetooth devices , which can prevent malicious bluetooth devices from masquerading as the same beacon identity and achieve accurate positioning.

Description

technical field [0001] The invention relates to the field of communication, in particular to a positioning technology based on bluetooth. Background technique [0002] The rapid development and popularization of mobile terminals such as mobile phones and handheld computers has led to the emergence and rapid development of indoor (or local area) positioning technology, which mainly uses wireless communication, base station positioning, inertial navigation positioning and other technologies to form a set of indoor positioning technology. Positioning system, so as to realize the position monitoring of people, objects, etc. in the indoor space. It has a wide range of needs and applications in many fields such as commercial applications, public safety and military scenarios. [0003] The current indoor positioning technology mainly uses devices that can generate electromagnetic signals such as Bluetooth, wireless access devices, and geomagnetism as reference devices. Among them...
