Multiplexed autonomous sensors and monitoring system and associated methods |
摘要 |
A sensor monitoring system and associated methods are provide that preferably include a plurality of sensors connected in parallel across a single pair of wires that include resistances of equal value placed in series between each sensor. This allows each sensor to measure the voltage dropped between itself and the monitoring system to determine its relative placement on the bus to autonomously assign itself a number to delineate to the monitoring system its relative location on the equipment or item being monitored. The sensors modulate their internal resistance to change the current on the bus to transmit their status to the monitoring system.
