Abstract
A system may include an air treatment assembly configured to deliver treated air to an enclosed space within a vehicle, at least one upstream sensor upstream from the air treatment assembly, and at least one downstream sensor downstream from the air treatment assembly. The upstream sensor(s) and the downstream sensor(s) are configured to detect at least one attribute of air, such as air pressure. An air treatment monitoring system is in communication with the sensors. The air treatment monitoring system receives one or more sensor signals from the sensors, and calculates an attribute differential (such as a pressure differential) based on the one or more signals.
Claims20
A system comprising:
- at least one air treatment assembly configured to deliver treated air to an enclosed space within a vehicle;
- at least one upstream sensor upstream from the at least one air treatment assembly;
- at least one downstream sensor downstream from the at least one air treatment assembly, wherein the at least one upstream sensor and the at least one downstream sensor are configured to detect at least one attribute of air;
- and
- an air treatment monitoring system in communication with the at least one upstream sensor and the at least one downstream sensor, wherein the air treatment monitoring system is configured to receive one or more sensor signals from the at least one upstream sensor and the at least one downstream sensor, and wherein the air treatment monitoring system is configured to calculate an attribute differential based on the one or more sensor signals.
A method of monitoring an air treatment assembly within a vehicle, the method comprising:
- receiving one or more air pressure signals detected by air pressure sensors that are positioned upstream and downstream from an air treatment assembly within a duct of the vehicle;
- and
- calculating a pressure differential based on the one or more air pressure signals.
An air treatment monitoring system configured to monitor an operative state of an air treatment assembly within a vehicle, the air monitoring system comprising:
- a pressure differential calculation unit that is configured to calculate a pressure differential between a first sensor signal received from a first sensor that is upstream in relation to the air treatment assembly and a second sensor signal received from a second sensor that is downstream in relation to the air treatment assembly;
- a parameter compensation factor determination unit that is configured to determine one or more parameter compensation factors related to the vehicle;
- and
- a compensated pressure calculation unit that is configured to calculate a compensated pressure differential based on the pressure differential and the one or more compensation factors.
