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.

Description

technical field [0001] The invention relates to an Internet of Things intelligent door lock and a door opening method thereof, which can automatically open the door in a fire, and in particular to an Internet of Things intelligent door lock and an opening method thereof that can automatically open a door in a fire situation, smooth a survival passage, and facilitate personnel escape. Background technique [0002] Modern smart door locks bring convenience and safety to public life, so more and more people accept and install smart door locks. But now smart door locks also have some hidden dangers. [0003] Smart door locks are mostly composed of circuit parts, motor drive parts, motor clutches, electronic lock bodies and other components. Due to the consideration of ensuring property safety in normal life situations, when the door lock is locked, multiple electronic and mechanical components need to be linked to unlock it. Generally, it needs to identify user information, mat...

Problems solved by technology

However, in case of disasters such as fires, the survival time is racing against time, and a delay of two or three seconds will cause major personnel and property losses; The clutch parts are damaged, which leads to the delayed opening of the door lock, which prevents the residents from escaping immediately. In real life, it has gradually become the norm for residents of high-rise buildings. Leaving the burning room as soon as possible has become an important preventive measure to reduce fire casualties.

[0004] How to release the locking mechanism of the door lock at the initial stage of the fire, prevent the door lock from being closed due to the failure of electronic devices, keep the door open, and keep the survival channel unblocked; and how to prevent false alarms from causing the door to open, causing property safety problems It has become an urgent problem to be solved for the smart door lock of the Internet of Things
