Abstract
A system for managing sensor power to a remote wireless condition monitoring sensor installed on a railway rolling stock. The system provides an energy harvester that derives wireless sensor power, a rechargeable battery connected to the energy harvester for supplying energy to the rechargeable battery and for powering the system, an antenna for sending signals to a remote database based on measured vibration and acceleration data, a central processing unit having a memory an arithmetic logic unit and a control unit for controlling a function of the system. The remote wireless condition monitoring sensor is protected from potentially fatal over voltage and under voltage conditions and the operating life is prolonged by entering dedicated modes of operation based on battery voltage and available energy capacity as instructed by the central processing unit. Also, a method for carrying out the function of the system.
