Building Occupancy Sensor Network

Abstract

A system for detecting and identifying occupants of rooms in a building works with an application allowing configurable control and actuation of various controller and actuators around the building and easy configuration of short range communication devices.

AI Technical Summary

Benefits of technology

The system provides energy-efficient Internet access, extends battery life of devices, and enhances building automation by accurately identifying and managing occupants, reducing energy costs and improving network performance.

Problems solved by technology

The recent proliferation of the communication-enabled devices requires a large amount of data being transferred to and from these devices.

While the current approach of using one network in a home or small building suffices when there are only a handful of devices communicating with the Internet, such as computers, tablets, thermostats and other large appliances, this solution quickly becomes insufficient and ineffective with the proliferation of number of the devices trying to access the Internet from inside of a building.

Large number of devices accessing one local area network (LAN) increases the burden on this network and its router to appropriately divide the network resources among all network nodes.

In addition to this, the cost of adding a device to a local wireless or wired network is significant and can be an economical barrier to its long-term, large-scale, successful deployment.

In addition to the component cost, there also is an energy cost associated with broadcasting relatively wide-band wireless signals, such as WiFi signals based on a variant of IEEE 802.11 specification.

This additional energy cost adds over time to the overall cost of ownership of each device and the entire network.

They do, however, have a relatively limited capability on their own.

Their greatest shortcoming is the lack of the ability to identify the person in the room—they cannot usually tell one building occupant from another or whether the person detected should or should not be allowed in the part of the building the sensors are installed in.
