Sensor for generating power management data

A control unit for a sensor, comprising:

• a computing unit configured to analyze the data available to the sensor, the data comprising measurement data of the sensor and data from an external data storage, the data from the external data storage comprising information on an expected duration of a power saving mode, and to generate the power management data based on the analysis of the measurement data of the sensor and the data from the external data storage,
• wherein the computing unit is configured to use the power management data to select a power saving mode from a plurality of available power saving modes of a wireless module of the sensor and to control the times of measurement intervals of the sensor,
• wherein the computing unit is configured to select extended discontinuous reception (eDRX) as the power saving mode if the expected duration of the power saving mode is a first time span,
• wherein the computing unit is configured to select Power Saving Mode (PSM) as the power saving mode if the expected duration of the power saving mode is a second time span which is longer than the first time span, and
• wherein the computing unit is configured to select disabling the wireless module as the power saving mode if the expected duration of the power saving mode is a third time span which is longer than the first time span and the second time span.

A method for scheduling measurement intervals and power management of a sensor, the method comprising:

• analyzing data available to the sensor, the data comprising measurement data of the sensor and data from an external data storage, the data from the external data storage comprising information on an expected duration of a power saving mode;
• generating power management data based on the analysis of the measurement data of the sensor and the data from the external data storage;
• using the power management data to select a power saving mode from a plurality of available power saving modes of a wireless module of the sensor and to control the times of measurement intervals of the sensor;
• selecting extended discontinuous reception (eDRX) as the power saving mode if the expected duration of the power saving mode is a first time span;
• selecting Power Saving Mode (PSM) as the power saving mode if the expected duration of the power saving mode is a second time span which is longer than the first time span;
• and
• selecting disabling the wireless module as the power saving mode if the expected duration of the power saving mode is a third time span which is longer than the first time span and the second time span.

A non-transitory program element that, when executed on a control unit or a computing unit of a sensor, instructs the control unit or the computing unit to perform the following step:

• analyzing data available to the sensor, the data comprising measurement data of the sensor and data from an external data storage, the data from the external data storage comprising information on an expected duration of a power saving mode;
• generating power management data based on the analysis of the measurement data of the sensor and the data from the external data storage,
• using the power management data to select a power saving mode from a plurality of available power saving modes of a wireless module of the sensor and to control the times of measurement intervals of the sensor;
• selecting extended discontinuous reception (eDRX) as the power saving mode if the expected duration of the power saving mode is a first time span;
• selecting Power Saving Mode (PSM) as the power saving mode if the expected duration of the power saving mode is a second time span which is longer than the first time span;
• and
• selecting disabling the wireless module as the power saving mode if the expected duration of the power saving mode is a third time span which is longer than the first time span and the second time span.
