Magnet-based detection system for detecting a movement of a movable object

A magnet-based detection system for detecting a movement of a movable object, the magnet-based detection system comprising:

• an excitation unit comprising at least one excitation magnet, the excitation unit being configured to generate an excitation magnetic field;
• and
• a sensor unit,
• wherein the sensor unit comprises:
• a power Wiegand module comprising,
• a power Wiegand coil, and
• a power Wiegand wire arrangement which is arranged at least partially within the power Wiegand coil, the power Wiegand wire arrangement being configured to generate a power output signal in the power Wiegand coil when the power Wiegand wire arrangement is excited by the excitation magnetic field;
• a sensor Wiegand module comprising,
• a sensor Wiegand coil, and
• a sensor Wiegand wire arrangement which is arranged at least partially within the sensor Wiegand coil, the sensor Wiegand wire arrangement being configured to generate a sensor output signal in the sensor Wiegand coil when the sensor Wiegand wire arrangement is excited by the excitation magnetic field,
• wherein,
• the sensor Wiegand wire arrangement is different from the power Wiegand wire arrangement, the difference comprising a different total Wiegand wire volume, and/or
• the sensor Wiegand coil is different from the power Wiegand coil, the difference comprising a different Wiegand coil inductance;
• an energy storage arrangement which is configured to store an electrical energy provided by the power output signal of the power Wiegand module;
• and
• an evaluation unit which is configured to evaluate the sensor output signal of the sensor Wiegand module so as to determine at least one movement parameter,
• wherein,
• either the excitation unit or the sensor unit is configured to be connected with the movable object so as to co-move therewith within a reference frame of the magnet-based detection system, and
• the excitation unit or the sensor unit which is not configured to be connected with the movable object is configured to be fixed within the reference frame of the magnet-based detection system.
