Monitoring solution for a conveyor system

A conveyor system wherein the conveyor system comprises:

• a drive machine,
• a conveyor control unit configured to control operation of a conveyor device,
• a sensor array comprising a plurality of sensors mounted to the drive machine and adapted to measure different properties of the drive machine,
• a processing unit associated with the drive machine and comprising a sensor fusion portion, wherein the processing unit is connected to the sensor array and configured to obtain and process measurement data from the sensor array so as to determine, by the sensor fusion portion of the processing unit at least one operational parameter of the drive machine from the measurement data obtained from the plurality of sensors of the sensor array to generate information about an operation of the drive machine, and
• a communication channel between the conveyor control unit and the processing unit,
• wherein at least one sensor of the sensor array is adapted to sense a stray magnetic field of a drive motor of the drive machine, and wherein the processing unit is configured to determine a rotor angle of the drive motor based on the measurement data obtained from the at least one sensor adapted to sense the stray magnetic field of the drive motor of the drive machine.
