Method for automatically calibrating a sensor module and a sensor module for detecting material containers in a storage or transport system

摘要

The present invention relates to a method for automatically calibrating a rocker-type sensor module (1) comprising a position or acceleration sensor, whereby the position of the sensor module (1) is determined by an angle γ with respect to a fixed spatial direction is measured and outputs an output signal depending on whether the measurement angle γ is less than or greater than the switching angle γ S . The method includes the following steps: setting the output signal to a first output value when the measuring angle γ exceeds the switching angle γ S ; set the switching angle γ S to a value corresponding to the measurement angle γ minus the “off” free pivot angle Δ O , as long as the value of the measurement angle γ continues to increase; setting the output signal as a second output value when the measurement angle γ falls below the switching angle γ S ; The measurement angle (γ) is continuously set to a value corresponding to a falling of the switching angle (γ S) to the measured angle (γ) plus "one" free pivot angle (Δ I). The invention also relates to a sensor module (1) designed for carrying out a method of this type.
