Method and system for calculating accurate battery percentage usage in wireless field devices
First Claim
1. A method for accurately calculating battery consumption in a wireless field device, said method comprising:
- providing a wireless field device having a radio board operatively connected to a sensor board, said sensor board operatively and electrically connected to a battery associated with said wireless field device, wherein slot structured events occur at said radio board;
determining a total current consumed by said radio board associated with said wireless field device based on a sum of a current consumed as a result of said slot structured events occurring at said radio board;
averaging a current consumed by said sensor board of said wireless field device with respect to a particular type of sensor and a reporting period thereof;
combining said current consumed by said radio board and said current consumed by said sensor board in said wireless field device in response to averaging said current consumed by said sensor board with respect to said particular type of said sensor and said reporting period to calculate a predictive value indicative of a remaining life of said battery associated with said wireless field device;
automatically monitoring said slot structured events and cumulative uptime data from an initial time said battery was placed in said wireless field device as a fresh battery; and
wherein said determining said current consumed by said radio board associated with said wireless device, further comprises;
determining said current consumed by said radio board associated with said wireless device based on said sum of said current consumed as a result of said slot structured events and said cumulative uptime data.

Abstract
Methods and systems are disclosed herein for accurately calculating battery consumption in a wireless field device. The total current consumed by a radio board associated with a wireless field device can be determined based on the sum of the current consumed as a result of particular events occurring at the radio board. The current consumed by a sensor board of the wireless field device can then be averated with respect to particular type of sensor. The current consumed by the radio board and the current consumed by the sensor board in the wireless field device can be combined to calculate a predictive value indicative of a remaining life of a battery associated with the wireless field device.
