AI Technical Summary
Existing magnetically shielded rooms struggle to maintain the static magnetic field strength and magnetic field fluctuation within a stable target range while meeting cleanliness and temperature control accuracy requirements. Electromagnetic noise and magnetic leakage generated by the core components of the environmental control system also affect shielding performance.
The system combines a passive shielding layer with an active magnetic compensation system. The magnetic field is gradually attenuated through the magnetic permeable layer, and the active magnetic compensation coil cancels out the geomagnetic field and residual magnetic field. The environmental control system is external to reduce magnetic interference. Combined with a multi-input multi-output control system and a precise temperature control sensor, it achieves uniform airflow distribution and temperature stability.
It achieves a high level of cleanliness and high temperature control precision in the magnetically shielded room, while maintaining the static magnetic field strength and magnetic field fluctuations within a stable target range, providing a stable environmental foundation.
