Subsequently, the electronic lock 300 will also retract the lock tongue into the door body 100 and maintain the state, thereby facilitating the escape of indoor personnel and the rescue of outdoor personnel.

[0053] In this embodiment, there are various fire trigger signals; first, when the temperature sensor detects that the temperature on one side of the door body 100 rises by more than 50 °C within 5 minutes and the temperature on the other side also continues to rise, the processor can determine that there is a fire; second, when the smoke sensor on one side of the door body 100 is triggered and the corresponding temperature sensor also detects a temperature increase, the processor can determine that there is a fire.
