A smart home indoor positioning method

Abstract

The invention discloses an intelligent home indoor positioning method, comprising the following steps: an environmental sound detection and recognition step; a sound signal uploading step: the voice receiving device sends the recognition result and signal strength of a successful matching recognition to a central controller. User position locating step: the central controller judges the position of the sound source according to the sound signal strength recognized by the voice receiving device and the position in the home space corresponding to the IPV6 address of the voice receiving device. The intelligent home indoor positioning method of the present invention determines the position of the speaker in the space by picking up the voice signal of the person in the home space through the voice receiving device, which can reduce the calculation amount of the central controller. The sound signal is used to determine the position of the speaker in the space. The sound has good penetration and diffraction, is not easily affected by furniture placement, and has high detection sensitivity.

Description

technical field [0001] The invention belongs to the technical field of smart homes, and in particular relates to an indoor positioning method for smart homes. Background technique [0002] A smart home is a multi-functional network system that uses advanced technologies such as computers, network communications, automatic control, and wireless networking to organically integrate the functions of various smart home appliances, and realize centralized control through home gateways or other types of intelligent communication devices. The spatial location of people (users) in a smart home is a basic technical issue in smart home applications. The indoor location information of a person can be used to adjust the working status of home appliances, accurately determine the object of voice commands, exercise estimation, transaction reminders, security warnings, etc. [0003] At present, there are mainly three implementation methods for indoor positioning. One is based on passive d...

Problems solved by technology

[0004] In order to solve the problem that the existing indoor positioning method needs to establish a sensor position information database, or the positioning reliability of bluetooth and wifi signals is poor due to reflection and occlusion, a smart home indoor positioning method is proposed, based on the voice intensity and voice receiving device IPV6 address positioning can solve the above problems
