Claim of US Patent No. 11,071,071


1. A computer implemented method for optimizing power supply life time of an industrial sensor platform comprising a processing unit, a power supply, and a transmitter, the method comprising:identifying an industrial sensor connected to the platform for measuring sensor measurement values;
verifying a functional setting of the platform;
determining sensor power consumption and sensor measurement time is of the identified industrial sensor;
determining transmission power consumption of the transmitter;
acquiring input parameter settings comprising an expected battery life time, a sensor reading interval Ts and periodic transmission interval Tw;
calculating an optimum for power supply life time, sensor reading interval Ts, and periodic transmission interval Tw, based on the sensor power consumption, the transmission power consumption, voltage of the power supply, and the functional setting of the platform;
adjusting settings for sensor reading interval Ts and periodic transmission interval Tw according to the optimum calculated.
