Problems solved by technology

However, this traditional detection and alarm method can only make a simple judgment of 0 and 1, that is, two states of alarm or normal. This detection and alarm method often easily causes false alarms. Changes in ambient temperature and other factors, the higher the probability of false positives

Abstract

The invention discloses a system with a dynamically adjusted smoke sensing threshold and an adjusting method. The method comprises the steps that the sensitivity of the smoke sensing threshold and a corresponding time period are set at the cloud; the cloud issues an instruction of the smoke sensing threshold; an operator IoT platform receives and caches the instruction and sends the instruction todetection equipment; and the equipment changes default configuration and restarts after detecting that the instruction is received.

Description

Technical field [0001] The present invention relates to the field of smoke sensing detection, and more particularly to a method of dynamically adjusting the smoke sensing threshold, a system having a dynamically adjusted smoke threshold. Background technique [0002] Existing smoke detectors are one of the most common and most quantities of probes in the world. It is widely used in home, shopping malls, hotels, office buildings, warehouses and other places. Smoke fire detectors are divided into point-type and line-like smoke fire detectors. Among them, the market is more use is a point-type sense of smoking fire detector, and the point detector is divided into ion-type and photoelectric firing detectors. The specific detection device based on photoelectric sensing type smoke detection uses a photoelectric sensor, and the internal installation of infrared pair is installed inside, and the infrared receiving pipe is not emitted in infrared light. When the soot enters an optical lab...
