DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-14 , a fire access control alarm device based on the Internet of Things, comprising: A fire monitoring module, including a sensor module 6, a controller and a video monitoring module 5; Access control module, including access control panel 2, door lock control module 3 and automatic door opening module 4; Alarm module 7, access control module is connected to alarm module 7, fire monitoring module is connected to alarm module 7; A door frame 1, a door panel 101 is hingedly connected to the rear side of the door frame 1; The automatic door opening module 4 includes: a fixed box 401, a guide rail 405, a rotating arm 402 and a driving motor 418. The fixed box 401 is fixedly installed on the rear side of the door frame 1. A circular shaft 406 is fixedly installed on the top of the rotating arm 402. The circular shaft 406 is rotatably installed on the top of the fixed box 401. A driven gear 407 is fixedly installed on the circular shaft 406. The driving motor 418 is fixedly installed in the fixed box 401. A driving shaft 409 is fixedly installed on the output shaft of the driving motor 418. A driving gear 408 is fixedly installed on the driving shaft 409. The driving gear 408 and the driven gear 407 are meshed with each other. A connecting column 403 is fixedly installed on the other end of the rotating arm 402. The guide rail 405 is fixedly installed on the rear side of the door panel 101. A sliding seat 404 is slidably sleeved on the outer side of the guide rail 405. The sliding seat 404 is rotatably sleeved on the outer side of the connecting column 403.

[0019] In this embodiment, the sensor module 6 includes a smoke sensor 601, a temperature sensor 602, a flame sensor 603, a gas sensor 604 and a fixing base 605. The smoke sensor 601, the temperature sensor 602, the flame sensor 603 and the gas sensor 604 are all fixedly mounted on the fixing base 605, and the fixing base 605 is fixedly mounted on the door frame 1; The smoke sensor 601 detects the smoke concentration in the air to identify early signs of fire. Smoke is an obvious feature of most fires in the early stages. If the sensor detects that the smoke concentration in the air exceeds a preset threshold (for example, a certain particle concentration), it may indicate that a fire is occurring or a fire source is burning. If the smoke sensor 601 detects a sudden increase in smoke concentration and this trend continues, it indicates that the possibility of a fire is high. The temperature sensor 602 detects changes in ambient temperature. Fires are usually accompanied by a sharp rise in temperature. The temperature sensor 602 monitors the ambient temperature. If the temperature rises rapidly and exceeds a certain set temperature threshold (such as 60°C, 100°C, etc.), this may indicate the occurrence of an ignition source or a fire. The temperature sensor 602 senses The temperature rise detected, especially the continuous temperature rise, combined with the signals of other sensors, may indicate that a fire is occurring or is about to occur. The flame sensor 603 is specifically used to detect the spectral characteristics of flames, especially the radiation of ultraviolet (UV) and infrared (IR). The flame sensor 603 can detect the radiation signal unique to flames. If the flame sensor 603 detects obvious flame radiation, especially in the early stage of a fire, the possibility of a fire is very high, and it is likely to have entered the stage of fire expansion. The gas sensor 604 can detect the concentration of harmful gases (such as carbon monoxide, carbon dioxide, methane, etc.) in the surrounding air. These gases are usually released in fires, especially carbon monoxide. During the fire, combustion will release a large amount of toxic gases, especially CO (carbon monoxide). The gas sensor can detect the changes in the concentration of these gases. If the concentration exceeds the preset safety threshold (for example, the CO concentration is higher than 30ppm), it indicates that a fire may have occurred. The detection of high concentrations of carbon monoxide, carbon dioxide, or other combustion gases indicates that the possibility of a fire is very high, especially that the flame may have started or is expanding. The fixing seat 605 is used to support and stabilize the sensor module to ensure that each sensor works accurately and reliably.
