Redundant monitoring
First Claim
1. A method of providing redundancy in an environmental monitoring device, comprising:
- combining a first sensor, one or more redundant sensors, and a plurality of control logic components;
monitoring a selected environmental condition using the redundant sensors;
measuring the selected environmental condition using the redundant sensors each reporting to a particular control logic component among the plurality of control logic components, each of the plurality of control logic components monitoring a sequence of such measurements; and
correlating corresponding monitored measurements from the sequence of measurements of each of the plurality of control logic components and determining whether a difference exists between the corresponding monitored measurements of each of the plurality of control logic components.

Abstract
Methods, mediums, systems, and devices for redundant monitoring are disclosed. One method of providing redundancy in an environmental monitoring device includes combining a first sensor, one or more redundant sensors, and a plurality of control logic components; monitoring a selected environmental condition using the plurality of sensors; measuring the selected environmental condition using the plurality of sensors each reporting to a particular control logic component among the plurality of control logic components, each of the plurality of control logic components monitoring a sequence of such measurements; and correlating corresponding monitored measurements from the sequence of measurements of each of the plurality of control logic components and determining whether a difference exists between the corresponding monitored measurements of each of the plurality of control logic components.

11. A method of providing redundancy in an environmental monitoring device,
comprising: -
combining a plurality of redundant sensors and a control logic component; monitoring a selected environmental condition using the plurality of redundant sensors; measuring the selected environmental condition using the plurality of redundant sensors each reporting to the control logic component, where the control logic component separately monitors a sequence of such measurements from each of the plurality of redundant sensors; and correlating with the control logic component corresponding measurements from the sequence of measurements of each of the plurality of redundant sensors and determining with the control logic component whether a difference exists between the corresponding monitored measurements of each of the plurality of redundant sensors.

12. A redundant environmental monitoring system, comprising:
-
a first sensor connected to a first control logic component and a second sensor connected to a second control logic component; individual output from the first control logic component and the second control logic component representing separate measurement values of an environmental condition sensed by the first and second sensors at substantially the same time point; a failsafe logic component that receives input of the individual output from the first control logic component and the second control logic component, where the failsafe logic component outputs an alert if a difference between the separate measurement values sensed by the first and second sensors at substantially the same time point exceeds a predetermined threshold value. - View Dependent Claims (13, 14, 15, 16, 17)
