System and method of reducing energy consumption of datalogger devices monitoring accelerometers tracking changes of location

A method of monitoring movement of an asset via attached accelerometer, comprising:

• a datalogger device, based on a predetermined sampling schedule, activating an accelerometer attached to an asset;
• the device implementing activity detection functionality of the accelerometer;
• the device making a first observation that the accelerometer is in moving mode, moving mode indicating that the asset is presently in motion;
• the device making a second observation that the accelerometer in motion is in a fast-moving mode;
• the device, based on the observations, reducing an update interval for server updates about mode to a first interval while maintaining the predetermined sampling schedule;
• the device making a third observation that the accelerometer is no longer in moving mode;
• and
• the device, based on the third observation, extending the update interval to a second interval as directed for still mode.

A method of conserving battery power of a datalogger device monitoring an accelerometer, comprising:

• a datalogger device, based on a predetermined sampling schedule, activating an accelerometer affixed to an observed asset;
• the device making a first observation that the accelerometer is in moving mode, moving mode indicating that the asset is presently in motion;
• the device activating a motion state based on the moving mode and based thereon initiating an update transmission to a server, the update transmission communicating the motion state;
• the device implementing a shortened interval for server update transmissions based on the motion state, the shortened interval shorter than a standard interval for still mode associated with the accelerator not moving;
• the device receiving a first message that the update transmission failed;
• the device incrementing an Unsuccessful Sync Counter from 0 to 1;
• the device, after observing a predetermined quantity of consecutive failed update transmissions and accompanying increments with each failure, extending the interval for update transmissions to the standard interval while maintaining the predetermined schedule for sampling;
• the device, upon receiving a second message that an update transmission was successful, continuing sampling at the predetermined schedule, and one of resuming the shortened interval upon detecting continuance of motion state and returning to the standard interval upon detecting discontinuance of the motion state.
