Maintenance-free photoelectric type smoke detector and test process thereof

Abstract

The invention relates to a maintenance-free photoelectric type smoke detector and a test process thereof. The maintenance-free photoelectric type smoke detector comprises at least two pairs of infrared ray emitting and receiving photoelectric sensors including a pair of normally open infrared ray emitting and receiving photoelectric sensors corresponding in use, and the rest are auxiliary infrared ray emitting and receiving photoelectric sensors corresponding to the normally open infrared ray emitting and receiving photoelectric sensors and used for detecting whether the normally open infrared ray emitting and receiving photoelectric sensors can work normally or not. The maintenance-free photoelectric type smoke detector has the advantages that the normally open infrared ray emitting and receiving photoelectric sensors can be detected in real time by the auxiliary infrared ray emitting and receiving photoelectric sensors through computer control, and the detection process is very convenient and accurate. The smoke detector can be remotely detected through the remote control of a computer so as to further facilitate the test on the detector, the working stability of the detector is ensured, and at the same time when the normally open infrared ray emitting and receiving photoelectric sensors are broken, the auxiliary infrared ray emitting and receiving photoelectric sensors can be used so as to ensure the continuous use of the detector, and the damage resistance capacity is improved.

Description

technical field [0001] The invention relates to a photoelectric smoke detector, in particular to a maintenance-free photoelectric smoke detector capable of remote testing. Background technique [0002] The current smoke detectors used in the industry all adopt ionization and photoelectricity, and the photoelectricity is the mainstream configuration. Now, both ionization and photoelectricity smoke detectors lack safe, simple and effective detection methods and methods, and cannot ensure Whether the smoke detector is working normally; and the traditional maintenance method is to simulate the fire and smoke on the spot manually to check whether the smoke detector is normal. However, in many cases, most smoke detectors have not done basic maintenance, which has buried many hidden dangers that cannot be alarmed at the initial stage of a fire.

[0002] The current smoke detectors used in the industry all adopt ionization and photoelectricity, and the photoelectricity is the mainstream configuration. Now, both ionization and photoelectricity smoke detectors lack safe, simple and effective detection methods and methods, and cannot ensure Whether the smoke detector is working normally; the traditional maintenance method is to simulate the fire and smoke on the spot manually to check whether the smoke detector is normal

However, in many cases, most smoke detectors have not done basic maintenance, which has buried many hidden dangers that cannot be alarmed at the initial stage of a fire.

[0003] The disadvantages of existing smoke detector maintenance and management are: 1. Traditional maintenance methods - manual on-site maintenance; 2. The safety and reliability of manual on-site maintenance are not high; 3. Traditional maintenance methods are easy to contaminate smoke detection detector, causing smoke detectors to need to be cleaned and reset

4. Traditional maintenance methods are costly
