METHOD AND SYSTEM FOR SELECTIVE RESET OF SENSORS POWERED FROM A COMMON POWER SUPPLY

摘要

A system and method for selective reset of a sensor powered from a common power supply. The system includes a power supply, a plurality of sensors, each sensor connected to the power supply, responsive to the power supply, configured to detect a sensed parameter and provide a signal corresponding to the parameter. The system also includes a transimpedance current limiting device connected in series with a sensor of the plurality of sensors that limits current from the sensor, a switching device connected in series with the transimpedance current limiting device, that is controllable to interrupt current flow through the sensor, and a controller connected to the plurality of sensors, the controller monitors various signals from at least one sensor and controls the switching device based on those signals, wherein the controller deactivates the switching device if the current from the sensor exceeds a selected threshold.
