The invention discloses a three-mode geomagnetic detection system and a method thereof. The system comprises a cloud server used for storing parking space state information, a power supply module usedfor supplying power to the system, a radar sensor used for measuring the distance between a parking space and a vehicle, a photosensitive sensor used for detecting the illuminance change of the parking space, a magnetoresistive sensor used for determining the parking space state by detecting the magnetic field intensity change of the area where the parking space is located, a processor used for controlling the radar sensor, the photosensitive sensor and the magnetoresistive sensor, and a communication module used for sending the parking space state to the cloud server. The power supply moduleis connected with the processor and the communication module, the processor is connected with the radar sensor, the magnetoresistive sensor and the communication module, and the communication moduleis connected with the cloud server. Parking space state change information can be monitored in real time through the photosensitive sensor and the magnetoresistive sensor, secondary precise confirmation is realized through the radar sensor, and the detection accuracy of the parking space state is ensured.
