Continuous calibration of sensors in a remotely monitored cooling system

An apparatus for managing refrigeration systems, comprising:

• one or more communication interfaces, including a wireless communication interface configured to couple the apparatus to a wireless communication network;
• a sensor interface circuit configured to receive temperature measurements that are continuously captured by clusters of sensors, the clusters of sensors being deployed at different locations within a temperature-controlled asset, each cluster of sensors including a plurality of sensors configured to measure temperature at the deployed location of the each cluster of sensors within a compartment of the temperature-controlled asset while the temperature-controlled asset is in operation;
• and
• a processing circuit configured to:
• continuously recalibrate each sensor in a first cluster of sensors based on the temperature measurements generated by the first cluster of sensors;
• automatically detect a calibration error based on a difference identified between temperature measurements in a time series of sensor data received from the first cluster of sensors and at least one other time series of sensor data received from the first cluster of sensors;
• and
• recalibrate a first sensor in the first cluster of sensors without manual intervention when differences between temperature cycles reported by the first sensor in the first cluster of sensors and temperature cycles reported by one or more other sensors in the first cluster of sensors vary from baseline differences,
• wherein each sensor in the first cluster of sensors is recalibrated during a continuous validation process involving the temperature-controlled asset.

A non-transitory processor-readable storage medium configured with code that, when executed by a processor, causes the processor to:

• receive temperature measurements that are continuously captured by clusters of sensors, the clusters of sensors being deployed at different locations within a temperature-controlled asset, each cluster of sensors including a plurality of sensors configured to measure temperature at the deployed location of the each cluster of sensors within a compartment of the temperature-controlled asset while the temperature-controlled asset is in operation;
• continuously recalibrate each sensor in a first cluster of sensors based on the temperature measurements generated by the first cluster of sensors;
• automatically detect a calibration error based on a difference identified between temperature measurements in a time series of sensor data received from the first cluster of sensors and at least one other time series of sensor data received from the first cluster of sensors;
• and
• recalibrate a first sensor in the first cluster of sensors without manual intervention when differences between temperature cycles reported by the first sensor in the first cluster of sensors and temperature cycles reported by one or more other sensors in the first cluster of sensors vary from baseline differences,
• wherein each sensor in the first cluster of sensors is recalibrated during a continuous validation process involving the temperature-controlled asset.
