Filed:

Dec 10, 2012

Appl. No.:

13/709371

Inventors:

Mark Alan Johnson - Wheaton IL, US
Stephen Michael Pasek - Bartlett IL, US
Kimble Allyn Vitkus - Sycamore IL, US
Russell Lee Sanders - Minnetonka MN, US
Mark Daniel Leasure - Eagan MN, US

International Classification:

G08C 15/04

US Classification:

34087017

Abstract:

A refrigerated container system is described that includes a wireless personal area network (WPAN) including a plurality of wireless sensor nodes and a coordinator node through which the sensors provide sensor data to a controller for the refrigerated container system. The wireless sensors and the coordinator incorporate a variety of features that ensure efficient utilization of battery life by preventing unintended pairing of sensors with other WPANs and excessive sensor signal processing arising from door chatter. Finally, pairing is performed without pressing a button on the wireless door sensor. Instead, the sensor's magnetic reed switch is enlisted to detect swiping of a magnet by a user to enter a pairing mode.
