WIRELESS SENSOR ARRAY FOR OCCUPANCY DETECTION IN PASSENGER VEHICLES

Last updated:

Abstract:

An occupancy detection system consists of a master controller for a series of joined receivers consisting of reader modules and transponder modules in close proximity to one another. The reader modules are able to both send power to the transponder modules wirelessly and receive signals from the transponder modules, where the transponder modules are sending signals based on information received from buckle sensors, occupancy sensors, or both. The transponder modules, set in each seat of the vehicle, will get the latch/unlatch signals from the buckles, and send this information back through the reader modules to the main controller. The main controller will interface with the vehicle to provide user interface notifications.
