Industrial mmWave radar sensors – Building automation
TI’s industrial mmWave solutions for building automation enable the detection and tracking of people both indoors up to 14m and outdoors at greater than 50m range. mmWave can be used for high accuracy occupancy detection, where the position and velocity of people can be used to trigger systems upon a person entering an area of interest, or moving in a particular direction.
mmWave sensors use onboard processing to reduce false detection by ignoring signatures of static objects that are not of concern such as chairs and desks, and dynamic objects such as trees and fans.
mmWave sensors provide high performance sensing that is environmentally robust to rain, fog, smoke, or ambient lighting. With no camera or optical lenses, mmWave is suitable for privacy-conscience applications.
TI’s Antenna on Package (AOP) technology simplifies the design process and reduces the system form factor for both ceiling and wall-mounted applications.
|Application||Occupancy sensing/people counting and tracking, automated doors and gates||Elderly monitoring/ fall detection||Motion detectors and IP Network Cameras|
|Benefits||3D detection and tracking of multiple people or objects (moving or static) with precise position and angle information. Simplify solution by ignoring non-moving (static) objects such as chairs and tables and filtering clutter from moving objects such as fans, curtains, or blinds.||Use object height information from the 3D detection and tracking sensor to determine the stance of a person and to determine the fall event without the use of a privacy-invasive camera.||Long-range object detection and tracking to complement video surveillance by improving perimeter or area intrusion detection with extremely low rate of fasle alarms.|
|Hardware||IWR6843ISK EVM||IWR6843ISK EVM|
|Example environments||Conference room (wall mount)||Open office (wall mount)||Open office/ conference room (overhead/ ceiling mount)||Living room/ bedroom/ bathroom||Outdoors|
|Example coverage area||6m x 6m||14m x 14m||3.5m radial (mounted at 3m height)||8m x 8m||25m x 100m|
|Example range||6m||14m||3.5m radial (mounted at 3m height)||8m||50m (up to 100m with Tx beamforming)|
|Algorithms implemented||3D Capon beamforming, static clutter removal (including chair, table, and more), static people detection, group tracking||Multiple object detection and group tracking, environmental clutter removal from trees and shrubs|
|Target applications||Presence or activity sensing for HVAC control, smart lighting, occupancy sensing for office desk space hoteling, pepole counter in retail automation and theft prevention, proximity sensing for automated doors or parking barriers||Elderly care, patient monitoring||IPNC- camera + Radar fusion, perimeter security, motion-activated oudoor smart lighting|
