Fire automatic door opening method of Internet-of-Things intelligent door lock

Abstract

The invention discloses a fire automatic door opening method of an Internet-of-Things intelligent door lock. The method comprises the steps that 1000, the indoor temperature is measured to be above afirst temperature threshold value, and the indoor smoke is measured to reach a first smoke threshold value; and 2000, all lock structures are opened so as to open a door. The first temperature threshold value is 55 DEG C or above. The first smoke threshold value is above 5%PBS / M and below 15%OBS / M. A temperature sensor and a smoke sensor are combined, specific parameters are set, and therefore thebeneficial effects that doors are opened at the early stage of fires, a mechanical unlocking mechanism is additionally arranged to avoid the situation that the door lock is closed due to failures ofelectronic devices, and it is guaranteed that doors are opened and not locked are achieved.
