The door open state detection assembly 11 includes a magnetic field meter 111 and a gyroscope 112. The magnetic field meter 111 and the gyroscope 112 are respectively connected with the main control assembly 12, the magnetic field meter 111 is used for detecting a current magnetic field, and the gyroscope 112 is used for calculating a current opening and closing angle of the door. The main control assembly 12 is used for determining whether the door is in a closed state according to the current magnetic field and the opening and closing angle.
Specifically, since the earth has a constant north-south magnetic field, the magnetic field meter 111 is used to measure the current magnetic field strength, and the main control assembly 12 compares the current magnetic field strength with the magnetic field strength in the preset door closing state, so as to determine whether the door is in the closing state. Furthermore, the gyroscope in the prior art can measure the angular velocity of the door rotation, and the current opening and closing angle of the door can be calculated by integrating the angular velocity. The current opening and closing angle is compared with the preset opening and closing angle of the door closing state, and whether the door is in the closing state or not can be determined.
