Adaptive power management in a battery powered system based on expected solar energy levels
A method and a gateway system for enabling adaptive power management. The gateway system is powered by a rechargeable battery that is coupled with a solar power source. A location reading indicating a location of the gateway system is transmitted at a first time. A solar profile is received from a management server. The solar profile indicates a measure of power expected to be generated at the location during an interval of time that occurs after the first time by the solar power source. The gateway system determines based on a current battery level of the rechargeable battery and the solar profile an optimal power usage plan for the gateway system and operates according to the optimal power usage plan during the interval of time.
1. A method, in a gateway system that is mounted on a mobile asset and powered by a rechargeable battery that is coupled with a solar power source, of enabling adaptive power management, the method comprising:
transmitting, by the gateway system, a location reading indicating a location of the gateway system at a first time;
receiving, by the gateway system from a server located in the cloud, a solar profile including one or more power measures expected to be generated by the solar power source at the location of the gateway system during an interval of time that occurs after the first time, wherein the solar profile was determined at the server based on a forecasting model and power measures previously recorded by another gateway system based on the location of the gateway system;
determining, by the gateway system, an optimal power usage plan for the gateway system based on a current battery level of the rechargeable battery and the solar profile; and
operating the gateway system according to the optimal power usage plan for the gateway system during the interval of time.
2. The method of claim 1 , wherein the optimal power usage plan for the gateway system ensures that the gateway system operates during the interval of time above a predetermined minimum energy threshold.
3. The method of claim 1 , wherein the optimal power usage plan for the gateway system causes the rechargeable battery of the gateway system to be charged while maintaining operation of the gateway system.
4. The method of claim 1 , wherein operating according to the optimal power usage plan for the gateway system during the interval of time includes modifying a frequency for reporting one or more sensor measurements from the gateway system to the server, wherein the one or more sensor measurements include at least a location reading indicating the location of the gateway system.
5. The method of claim 1 , wherein the method further comprises:
determining whether a level of power generated by the solar power source at a given time during the interval of time is less than an expected power measure at the given time determined based on the solar profile; and
responsive to determining that the level of power generated by the solar power source is less than an expected power measure at the given time, triggering an alert that causes the gateway system to operate based on an updated power usage plan.
6. The method of claim 1 further comprising:
transmitting, to the server, one or more power measures generated by the solar power source at a given location and a given time.
7. A gateway system that is mounted on a mobile asset and powered by a rechargeable battery that is coupled with a solar power source, for enabling adaptive power management, the gateway system comprising:
a non-transitory computer readable storage medium to store instructions; and
a processor coupled with the non-transitory computer readable storage medium to process the stored instructions to:
transmit, by the gateway system, a location reading indicating the location of the gateway system at a first time;
receive, by the gateway system from a server located in the cloud, a solar profile including one or more power measures expected to be generated by the solar power source at the location of the gateway system during an interval of time that occurs after the first time, wherein the solar profile was determined at the server based on a forecasting model and power measures previously recorded by another gateway system based on the location of the gateway system;
determine, by the gateway system, an optimal power usage plan for the gateway system based on a current battery level of the rechargeable battery and the solar profile; and
operate the gateway system according to the optimal power usage plan for the gateway system during the interval of time.
8. The gateway system of claim 7 , wherein the optimal power usage plan for the gateway system ensures that the gateway system operates during the interval of time above a predetermined minimum energy threshold.
9. The gateway system of claim 7 , wherein the optimal power usage plan for the gateway system causes the rechargeable battery of the gateway system to be charged while maintaining operation of the gateway system.
10. The gateway system of claim 7 , wherein to operate according to the optimal power usage plan for the gateway system during the interval of time includes to modify a frequency for reporting one or more sensor measurements from the gateway system to the server, wherein the one or more sensor measurements include at least a location reading indicating the location of the gateway system.
11. The gateway system of claim 7 , wherein the processor is further to:
determine whether a level of power generated by the solar power source at a given time during the interval of time is less than an expected power measure at the given time determined based on the solar profile; and
responsive to determining that the level of power generated by the solar power source is less than an expected power measure at the given time, trigger an alert that causes the gateway system to operate based on an updated power usage plan.
12. The gateway system of claim 7 , wherein the processor is further to:
transmit, to the server, one or more power measures generated by the solar power source at a given location and a given time.
