Control system with asynchronous wireless data transmission
First Claim
1. A control system with asynchronous wireless data transmission, the control system comprising:
- a wireless sensor comprising;
a measurement device configured to collect a plurality of samples of a measured variable at a plurality of different sampling times;
memory configured to store the plurality of samples of the measured variable;
a transmission generator configured to generate a compressed data object comprising at least one of the plurality of samples of the measured variable or a filtered plurality of samples of the measured variable; and
a wireless radio configured to transmit the compressed data object as a single transmission at a transmission time asynchronous with at least one of the sampling times; and
a controller comprising;
an object decompressor configured to extract at least one of the plurality of samples of the measured variable or the filtered plurality of samples of the measured variable from the compressed data object; and
a feedback controller configured to use at least one of one or more of the extracted samples of the measured variable or one or more of the extracted filtered samples of the measured variable to modulate a control signal for a plant that operates to affect the measured variable.

Abstract
A control system with asynchronous wireless data transmission includes a wireless sensor and a controller. The wireless sensor includes a measurement device configured to collect a plurality of samples of a measured variable at a plurality of different sampling times, a transmission generator configured to generate a compressed data object containing the plurality of samples of the measured variable, and a wireless radio configured to transmit the compressed data object at a transmission time asynchronous with at least one of the sampling times. The controller includes an object decompressor configured to extract the plurality of samples of the measured variable from the compressed data object and a feedback controller configured to use one or more of the extracted samples of the measured variable to modulate a control signal for a plant that operates to affect the measured variable.

11. A method for asynchronously transmitting samples of a measured variable from a wireless sensor to a controller, the method comprising:
-
collecting a plurality of samples of the measured variable at the wireless sensor at a plurality of different sampling times; storing the plurality of samples of the measured variable in memory of the wireless sensor; generating, by the wireless sensor, a compressed data object comprising at least one of the plurality of samples of the measured variable or a filtered plurality of samples of the measured variable; transmitting the compressed data object from the wireless sensor to the controller via a wireless radio as a single transmission at a transmission time asynchronous with at least one of the sampling times; extracting at least one of the plurality of samples of the measured variable or the filtered plurality of samples of the measured variable from the compressed data object at the controller; and using at least one of one or more of the extracted samples of the measured variable or one or more of the extracted filtered samples at the controller to modulate a control signal for a plant that operates to affect the measured variable. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
