step S2.1: determining a second door external signal through the first array antenna and the metal plate to determine that only the inner side of the door is unlocked;
step S2.2: the second door inside signal and the second door outside signal are determined by the first array antenna, the metal plate and the second array antenna, and the unlocking signal is prioritized to determine whether the door is unlocked inside or outside.
7. The intelligent door lock unlocking method according to claim 6, wherein the step S2.1 is implemented as the following steps:
step S2.1.1: the intelligent door lock comprises a first array antenna, a metal plate and a second array antenna, wherein the first array antenna is arranged on the outer side of a door of the intelligent door lock, and the metal plate is arranged on one side, away from the outer side of the door, of the first array antenna so as to determine the direction of the outer side of the door of the intelligent door lock;
step S2.1.2: the communication module is activated and detects whether a second door external signal located on the door outer side of the positive direction of the intelligent door lock exists within a preset second range, if yes, verification is conducted to judge whether the second door external signal is an unlocking signal, and if not, the intelligent door lock enters a dormant state.
8. The intelligent door lock unlocking method according to claim 6, wherein the step S2.2 is implemented as the following steps:
step S2.2.1: the intelligent door lock comprises a first array antenna, a metal plate and a second array antenna, wherein the first array antenna is arranged on the outer side of a door of the intelligent door lock, the metal plate is arranged on one side, far away from the outer side of the door, of the first array antenna, and the second array antenna is arranged on one side, far away from the first array antenna, of the metal plate so as to determine the inner side direction and the outer side direction of the door of the intelligent door lock;
step S2.2.2: the communication module is activated and detects whether a second door external signal positioned on the door external side in the positive direction of the intelligent door lock and a second door internal signal positioned on the door internal side in the positive direction of the intelligent door lock exist in a preset second range;
step S2.2.3: if only the second door external signal is detected, checking is carried out to judge whether the second door external signal is an door external unlocking signal or not, and if the second door external signal does not exist, the door external unlocking signal enters a dormant state;
step S2.2.4: if the second door external signal and the second door internal signal are detected simultaneously, the second door external signal is firstly verified to judge whether the second door external signal is an external unlocking signal or not, and if the second door external signal is the external unlocking signal, the priority judgment is carried out on the internal unlocking signal, so that the final unlocking signal is determined.
