Autonomous surveillance system for use in monitoring object e.g. vehicle, has evaluation circuit that sets function of occurrence of electrical pulse in logging mode to save timestamp

摘要

The autonomous surveillance system (1) has a force detector (4) for generating electrical pulse at an occurrence of force. An energy storage device (3) has memory elements (31) for receiving and storing the pulse in the electric existing electrical energy. An evaluation circuit (2) sets a function of the occurrence of the electrical pulse in a logging mode to save a timestamp. A clock unit (9) with a power supply (91) is provided to provide the timestamp. An independent claim is included for a method for operating autonomous surveillance system.
