METHOD FOR ESTIMATING A DURATION DURING WHICH A ROLLING SHUTTER ACTUATOR IS POWERED OFF

摘要

The method for estimating a duration during which an actuator is not supplied with power is characterized by having the following steps: charging a power storage element; stopping the supply of power to the actuator; supplying power to a microcontroller with the aid of the power of the storage element; initializing one or more memories and then modifying the contents of the first memory with the aid of a clock; if the microcontroller is supplied by the storage element during a duration greater than a predetermined duration, storing a particular value in the first memory or in one of the memories; supplying the actuator with power; reading the value stored in the memory, and; inferring from this value if the duration separating the event of the second step from the event of the fifth step is greater than or less than the predetermined duration value.
