Problems solved by technology

These areas are far away from the smart lock. Due to the slow spread of smoke, when the fire causes smoke to trigger the smart lock alarm, it is likely that the fire is already very serious, and it is also possible that the control circuit has been destroyed by high temperature before the alarm and the alarm cannot be realized.

[0038] combined with Figure 1-5 , a smart lock with a fire alarm function in this embodiment includes a power supply located in the lock body, a main control module, a motor module, a key scanning module, a wireless communication module, an alarm device, an analog signal processing module, an analog-to-digital conversion module and The digital signal processing module also includes an infrared detection element 1 wirelessly or electrically connected to the smart lock 2, wherein the power supply is connected to the main control module, the motor module, the key scanning module, the wireless communication module, the alarm device, and the infrared detection element 1 , the analog signal processing module, the analog-to-digital conversion module, and the digital signal processing module are all electrically connected, and the main control module is electrically connected with the button scanning module, the motor module, the wireless communication module, the digital signal proce...

Embodiment 2

[0042] combined with Figure 1-5 , an intelligent lock with a fire alarm function of this embodiment, compared with the technical solution of embodiment 1, the infrared detection element 1 is located on the surface of the rear panel of the intelligent lock 2 or at a place to be detected in the house.

[0043] The infrared detection element 1 is located on the panel surface of the rear panel of the smart lock 2, that is, the inner side of the door 3, which is beneficial for detecting the environment in the room. There can be more than one infrared detecting element 1, and it can also be arranged in places prone to fire such as rooms and kitchens. The infrared detection element 1 arranged on the surface of the smart lock 2 is electrically connected with the smart lock 2 , and the infrared detection element 1 arranged in the room or the kitchen is wirelessly connected with the smart lock 2 . A plurality of infrared detection elements 1 can promptly detect every corner of the hom...

Embodiment 3

[0045] combined with Figure 1-5 , an intelligent lock with a fire alarm function in this embodiment, compared with the technical solutions of Embodiment 1 or 2, the infrared detection element 1 includes an electrically connected infrared sensor and a second wireless communication sending module, and the infrared The sensor includes an optical system, a detection element and a conversion circuit.

[0046] Infrared rays are invisible rays, and all substances above absolute zero (-273.15°C) can produce infrared rays. The higher the temperature of the object, the shorter the wavelength of the radiated infrared rays, and the shorter the infrared wavelength, the greater the energy. The infrared sensor includes three parts: optical system, detection element and conversion circuit. The optical system can pass through the infrared light, and the infrared light is irradiated onto the detection element. The detection element is a thermal detection element, the most common of which is...

Abstract

The invention discloses an intelligent lock having a fire warning function, and belongs to the technical field of intelligent locks. The intelligent lock comprises a power supply located inside a lockbody, a master control module, a motor module, a key scanning module, a wireless communication module, a warning device, an analog signal processing module, an analog-to-digital conversion module anda digital signal processing module and further comprises an infrared detection element connected with the intelligent lock wirelessly or electrically. The warning method includes the following stepsthat the infrared detection element acquires infrared signals in a room, the analog signal processing module, the analog-to-digital conversion module and the digital signal processing module perform signal processing and threshold value judgment on the infrared signals, and the master control module controls the warning manner according to the judgment result. According to the technical problem that intelligent locks warn untimely in case of fires in the prior art, the intelligent lock has the advantages that whether a fire occurs can be judged, and the intelligent lock can warn when the firejust breaks out and can be unlocked automatically when the fire reaches the certain severity degree so as to guarantee the safety of people.

Description

technical field [0001] The invention relates to the technical field of intelligent locks, in particular to an intelligent lock with a fire alarm function. Background technique [0002] Many smart locks currently on the market do not have a fire alarm function. Fire is a common disaster in our daily life. If the fire can be detected in time at the initial stage, a disaster will be avoided. If it is not found in time, it will cause economic losses in the slightest and casualties in severe cases. [0003] The patent notification number is CN204457148U, a smart lock capable of sensing smoke. When a fire breaks out, the smoke sensing device on the smart lock senses the smoke and then triggers the alarm device and the unlocking device. [0004] In actual application scenarios, the location of the smart lock in the house is generally on the outer anti-theft door. Fires often occur in the high-power electricity consumption area or kitchen area of ​​the house, and these areas are...
