Patent Number: ZL 2025 1 0925999.9

Authorization Announcement Number: CN120452160B

Patent Application Date: July 7, 2025

Authorization Announcement Date: September 5, 2025

The following is a brief description of this patent:

1. Technical Field

This application relates to the technical field of fire detection and alarm, and in particular to a method, system, and storage medium for detecting abnormal states of point-type explosion-proof smoke detectors.

2. Background Technology

A point-type explosion-proof smoke detector is a fire detection device used in flammable and explosive hazardous environments. By detecting changes in smoke concentration in the environment, it issues timely alarms in the early stage of a fire, and is widely used in industrial production scenarios such as petrochemical, coal mining, and natural gas extraction. Its working principle is usually based on photoelectric sensing or ion sensing technology; when smoke particles enter the sensing area, the alarm mechanism is triggered by changing the light path or ionization balance.

In industrial production scenarios, point-type explosion-proof smoke detectors face complex and harsh working environments. Petroleum refining workshops have high temperature, high humidity, and corrosive gases, while underground coal mines are filled with a large amount of dust and gas. These environmental factors not only impose extremely high requirements on equipment stability, but also easily lead to equipment failures.

Since the sensing channel of the detector needs to be connected to the outside to detect smoke, foreign substances such as dust, powder, and insects in the environment can easily enter the equipment housing through the channel. The accumulation of these foreign substances on the sensing element interferes with the normal optical or ion detection process, causes distortion of sensing data, and leads to false alarms or missed alarms of the smoke detector. More seriously, long-term accumulated foreign substances may also cause faults such as internal circuit short circuits.

3. Invention Content

In order to detect the abnormal states of point-type explosion-proof smoke detectors in harsh working environments, this application provides a method, system, and storage medium for detecting abnormal states of point-type explosion-proof smoke detectors.

In the first aspect, this application provides a method for detecting abnormal states of point-type explosion-proof smoke detectors, adopting the following technical solutions.
