Wireless aircraft cabin pressure control system utilizing smart pressure sensors
First Claim
1. A pressure control system, comprising:
- a first sensor that includes a first function sensor configured to detect a functional measurement;
a second sensor that includes a second function sensor configured to detect the functional measurement in a different way than the first function sensor, wherein the first sensor and the second sensor generate processed data from the functional measurements, the processed data including time-based rate computations on the functional measurements; and
a first receiving unit and a second receiving unit connected to share the first sensor and the second sensor over a wireless network to receive the processed data from the first sensor and the second sensor;
wherein the first receiving unit is connected to the first sensor by a second network different from the wireless network to receive the processed data from the first sensor, where the first sensor is not shared with the second receiving unit over the second network, and the processed data is output in a format so that the first receiving unit uses the processed data in the format without further processing.

Abstract
A pressure control system includes a first sensor, and a second sensor which is dis-similar to the first sensor, where the second sensor generates a same processed data as the first sensor does, but in a way different from the first sensor does. A receiving unit is connected to the first sensor and the second sensor by a wireless connection to receive the processed data from the first sensor and the second sensor. In addition, the receiving unit is connected to the first sensor by a second connection different from the wireless connection to receive the processed data from the first sensor. Additional receiving units are connected to the first sensor and the second sensor by the wireless connection to receive the processed data.
