Problems solved by technology

[0002] Existing smoke alarm devices usually give an alarm as long as there is smoke, which can neither distinguish the level of smoke nor realize different levels of alarms. When the smoke alarm device is triggered, the fire control system will often be fully triggered, and corresponding treatment cannot be performed. measures, manpower, financial resources and time are greatly wasted

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0019] A hierarchical smoke alarm method, comprising the following steps:

[0020] Train the entry depth of smoke with different concentrations in the irregular rotary channel, and divide the smoke level according to the depth of the smoke entering the irregular rotary channel; the entry depth L is

[0021]

[0022]

[0023] In the formula, L is the depth that the smoke can flow after being restricted by frictional resistance in the channel, P is the frictional resistance, ρ is the density of the smoke, V is the flow velocity of the smoke in the channel, R is the radius of the smoke entrance, and C is the roughness coefficient of the smoke and the channel, S is the turning slope of the irregular turning channel;

[0024] Smoke sensors are respectively installed at the positions corresponding to the ent...

Abstract

The invention discloses a graded smoke alarm method and a graded intelligent control smoke alarm device. The method comprises the steps of: training the entering depth of smoke with different concentrations in an irregular rotating channel, and dividing smoke grades according to the entering depth of the smoke in the irregular rotating channel, respectively arranging smoke sensors at positions, corresponding to the entering depths of different grades of smoke, in the irregular rotating channel, using the smoke sensor for detecting the depth of smoke entering the irregular rotating channel, andsending an alarm signal of a corresponding grade through a communication unit. A traditional smoke alarm device is improved according to the flow characteristics of smoke, a plurality of smoke sensors are arranged in the irregular rotating channel in the depth direction, the smoke sensors are used for detecting the entering depth of the smoke, alarm signals of corresponding grades are sent out according to the entering depth of the smoke, and graded alarm is achieved. Therefore, corresponding processing measures are configured according to graded alarm, and waste of manpower, financial resources and time can be greatly reduced.

Description

technical field [0001] The invention relates to the field of fire safety protection, in particular to a hierarchical smoke alarm method and a hierarchical intelligent control smoke alarm device. Background technique [0002] Existing smoke alarm devices usually give an alarm as long as there is smoke, which can neither distinguish the level of smoke nor achieve different levels of alarms. When the smoke alarm device is triggered, the fire control system will often be fully triggered and no corresponding treatment can be performed. Measures, manpower, financial resources and time are greatly wasted. Contents of the invention [0003] The purpose of the present invention is to provide a hierarchical smoke alarm method and a hierarchical intelligent control smoke alarm device, which can realize hierarchical alarm, and can greatly reduce the waste of manpower, financial resources and time through corresponding processing measures. [0004] In order to achieve the above object...
