Problems solved by technology

[0005] However, the above two methods have certain disadvantages. (1) It is not accurate to simply detect the smoke through the photoelectric sensor, so the smoke that often comes from a place far outside the device will also cause the sensor to operate, so It will lead to misjudgment; (2) Various current video detection algorithms are inaccurate, and often use other features of the target area as smoke to alarm

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] figure 1 It is a schematic diagram of a dual-threshold smoke alarm system according to an embodiment of the present invention. Such as figure 1 As shown, the smoke alarm system according to the embodiment of the present invention includes a front end, a base station (not shown), a cloud (not shown), and a back end (not shown). The front end includes a photoelectric sensor module, a communication module, an alarm module, a control module, and a power temperature module.

[0028] Among them, the photoelectric sensor module is used to collect smoke data, the control module is electrically...

Abstract

The invention discloses a dual-threshold smoke alarm system which comprises a front end, a base station, a cloud end and a back end. The front end comprises a photoelectric sensing module, a communication module, a control module, an alarm module and a power supply temperature module. The alarm operation is carried out through a multi-parameter fusion method, and dual smoke thresholds and a temperature threshold are set according to the method. The alarm accuracy is improved. The probability of false alarms is greatly reduced.

Description

technical field [0001] The invention relates to the monitoring field, and more specifically relates to a double-threshold smoke alarm system. Background technique [0002] The existing smoke alarm system is composed of two parts: one is an inductive sensor for detecting smoke, and the other is a very loud electronic speaker, which can warn people in time if danger occurs. Its main components include a smoke detection device and a buzzer alarm device. [0003] However, the current smoke detection device is mainly based on two methods, one is based on the photoelectric sensor smoke detection, the specific detection device uses a photoelectric sensor, and an infrared pair tube is installed inside it, and the infrared receiver tube cannot receive the smoke when there is no smoke. When the infrared light emitted by the infrared emitting tube enters the optical labyrinth, the receiving tube receives the infrared light through refraction and reflection, and the buzzer alarm module...
