Smoke alarm control method based on computer processing and system thereof

Abstract

The invention discloses a smoke alarm control method based on computer processing and system thereof, relating to the field of smoke sensor. The smoke alarm control method includes that during the debugging, the smoke sensor acquires the environment smoke values and sends the values to an environment test module, the environment test module detects the environment to obtain the environment intrinsic state; the smoke sensor acquires environment smoke data and sends the smoke data to a value weight mean value processing module, the value weight mean value processing module calculates the smoke weight mean value (as shown in the description); the smoke alarm solution module determines whether the smoke value of the current environment is in a dangerous state based on the smoke weight mean value (as shown in the description) and the environment intrinsic state; and if the smoke value is in a dangerous state, a controlled relay is pulled in or disconnected. The invention further discloses a smoke alarm control system based on computer processing. The smoke alarm control method can improve the accuracy of smoke alarm and prevents smoke false alarm or error alarm.

Description

technical field [0001] The invention relates to the field of smoke sensors, in particular to the field of smoke alarm control. Background technique [0002] There is an optical maze inside the photoelectric smoke sensor, and an infrared tube is installed. When there is no smoke, the infrared receiving tube cannot receive the infrared light emitted by the infrared emitting tube. When the smoke enters the optical labyrinth, the receiving tube receives the infrared light through refraction and reflection. light, the intelligent alarm circuit judges whether the threshold is exceeded, and if so, an alarm is issued. [0003] The photoelectric smoke sensor can be divided into dimming type and scattered light type; among them, the detection chamber of the dimming photoelectric smoke sensor is equipped with a light-emitting device and a light-receiving device. Under normal circumstances, the light-receiving device receives a certain amount of light emitted by the light-emitting devi...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, the smoke alarm system in the factory generally sets the same smoke alarm threshold for the same smoke sensor. This method does not take into account that the smoke background value may be different at different times and in different areas, and the smoke value cannot be accurately determined. cause false positives or false positives

At the same time, the measurement accuracy of the existing analog smoke sensors is poor, and the average value filter is generally used for the smoke data filtering, and the precision is also low, and the ambient smoke value cannot be accurately obtained.
