SYSTEM AND METHOD FOR USER PROFILE ENABLED SMART BUILDING CONTROL

摘要

A central controller for device automation can control output devices (e.g. automated lights and speakers) based on calculating the indoor location of a person. In familiar surroundings (e.g. homes), people may leave their favorite wireless devices unattended (e.g. smartphones and tablet PCs) and in general people exhibit varying proximity to their mobile wireless devices. Hence, the indoor locations of mobile wireless devices are of variable importance when calculating indoor occupant locations. (e.g. exhibiting highly-correlated locations when handheld). In one embodiment, the central controller aggregates wireless signals from mobile wireless devices. The central controller calculates one or more mobile device location estimates and person-to-device proximities from the wireless signals. The central controller uses each person-to-device proximity to weight the corresponding mobile device location in a calculation to estimate the occupancy of the region of the building and controls an output device based on the occupancy estimate.

主权项

1. A method comprising:
receiving proximity indications from a mobile wireless device,
wherein the proximity indications are capable of indicating the presence of a person in the vicinity of the mobile wireless device, obtaining for the mobile wireless device a mobile device location estimate, generating for the mobile wireless device a corresponding weight,
wherein the weight is generated by processing the proximity indications to determine a measure of proximity between one or more people and the mobile wireless device,wherein upon generation the weight corresponding to the mobile wireless device indicates a measure of proximity of one or more people to the mobile wireless device, weighing the mobile device location estimate according to the weight, and thereby determine at least in part an occupancy estimate for a region of a building,
wherein the weight functions to modulate an aspect of the mobile device location estimate in a process to determine the occupancy estimate, generating an output signal,
wherein an aspect of the output signal is based on the occupancy estimate,wherein the output signal is operable to control an aspect of an output device, and transmitting from a transmitter the output signal.
