A smoke sensing alarm device based on the Internet of Things

Abstract

The invention relates to the technical field of fire safety devices, in particular to a smoke sensing alarm device based on the Internet of Things, including: a smoke sensing device 1 and a smoke sensing device 2; the smoke sensing device 1 is a cylindrical structure with a closed upper part and an open lower end, It is equipped with a smoke sensor, an audible and visual alarm module, and a communication module inside; when the light passes through the dust accumulated inside the shell two, it will hinder the light reflection, so that the light passing through the second diversion hole, the third diversion hole and the sixth diversion hole , the light intensity derived from the diversion hole seven is reduced, and the light intensity passing through the SLR glass is reduced, and people can intuitively judge the dust accumulation inside the shell two; and the light intensity reflected to the photosensitive sensor through the dust accumulation is also reduced, so that The control module obtains the corresponding detection data; at the same time, the hardware linkage monitoring and door control of the first smoke sensing device and the second smoke sensing device, the collected data are compared with each other, and then feedback and early warning are performed, which improves the detection accuracy and avoids false alarms.

Description

technical field [0001] The invention relates to the technical field of fire safety devices, in particular to a smoke sensing alarm device based on the Internet of Things. Background technique [0002] Smoke alarms, also known as fire smoke alarms, etc., are powered by the bus, networked with fire alarm controllers, and communicate to form an alarm system. This type of smoke alarm device is generally called a smoke detector. With the improvement of people's living standards and fire awareness Improvement, smoke alarms have been widely used in people's lives. [0003] Existing smoke alarm devices commonly include ion smoke sensor, photoelectric smoke sensor, infrared beam smoke sensor, etc. Since the smoke alarm device is generally installed in a fixed position, the smoke inlet is exposed to the air, and dust enters through the smoke inlet. The inside of the smoke alarm device, resulting in a lot of dust inside the smoke alarm device. When the airflow passes, the dust is easy...

Problems solved by technology

[0003] Existing smoke alarm devices commonly include ion smoke sensor, photoelectric smoke sensor, infrared beam smoke sensor, etc. Since the smoke alarm device is generally installed in a fixed position, the smoke inlet is exposed to the air, and dust enters through the smoke inlet. The inside of the smoke alarm device, resulting in a lot of dust inside the smoke alarm device. When the airflow passes, the dust is easy to contact with the smoke sensor and cause false alarms. The existing smoke alarm device cannot intuitively let the user understand The dust accumulation inside the smoke alarm device, and then remind the user that it needs to be cleaned or replaced to avoid false alarms

[0004] Existing smoke sensors are generally more sensitive. When there is a small amount of smoke or water vapor in contact with it, the smoke sensor will activate and trigger an alarm. In daily life, for example, when a user boils water, more water vapor will be generated. The water vapor continues to rise and evaporate. When a part of the smoke alarm device enters the interior of the smoke alarm device and contacts the smoke sensor, the smoke alarm device will generate false alarms. Further, with the rapid development of information technology, home IoT sharing has become the pursuit of people. , existing smoke detectors lack signal sharing
