Internet of Things intelligent door lock with fire automatic door opening function

Abstract

The invention provides an Internet of Things intelligent door lock with a fire automatic door opening function. The Internet of Things intelligent door lock comprises a main lock module, an auxiliarylock module and a door lock structure. The auxiliary lock module is located on the inner side of a door. The auxiliary lock module comprises a temperature sensor and a smoke sensor. The temperature sensor is used for measuring the indoor temperature, and the temperature sensing end of the temperature sensor is located in the indoor environment. The smoke sensor is used for measuring indoor smoke,and the smoke sensing end of the smoke sensor is located in the indoor environment. When the temperature sensing end measures that the indoor temperature is a first temperature threshold value or above and the smoke sensing end measures that the indoor smoke reaches a first smoke threshold value, all lock structures in the door lock structure are opened in order to open the door. The first temperature threshold value is 55 DEG C or above. The first smoke threshold value is 5% OBS / M or above and below 15% OBS / M. The temperature sensor and the smoke sensor are combined, specific parameters are set, and the Internet of Things intelligent door lock has the beneficial effects that the door is opened at a fire behavior initial stage, and a mechanical unlocking mechanism is additionally arranged,so that the situation that a door lock is closed as an electronic device fails is avoided, and it is guaranteed that the door is opened instead of being locked.

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
