Smoke-sensitive temperature-sensitive detection alarm

Abstract

The invention discloses a smoke-sensing and temperature-sensing detection alarm, comprising a base, the base includes a flame-retardant layer and a shell, the flame-retardant layer is laid on the outer wall of the shell, and a temperature sensor and a smoke sensor are installed on the bottom of the base And the protective cover, the temperature sensor and the smoke sensor are located inside the protective cover. The protective cover includes a flame-retardant layer and a shell. The flame-retardant layer is laid on the outer wall of the shell. There are data collector, central control module, data memory and GPRS communication module. The smoke-sensing and temperature-sensing alarm device has a simple structure, and when used, its function will not be affected by the interference of the external environment.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to a smoke and temperature detection alarm. Background technique [0002] Indoor fire alarm systems usually use smoke detectors and / or heat detectors to detect smoke and temperature signals. When the smoke concentration reaches a certain value or the temperature reaches a certain value, an alarm will be issued. These detectors can be used independently. There is an independent data analysis circuit and an independent alarm, and the detection signal can also be sent to the central processing system, which performs unified data processing, and when the alarm standard is reached, the alarm system will issue an alarm. At present, these technologies have two defects. When the detector fails or is disturbed by the outside world, false alarms or false alarms will occur. The second is that the photoelectric smoke detector uses the scattering principle. The scattering intensity of light gene...

Problems solved by technology

At present, these technologies have two defects. When the detector fails or is disturbed by the outside world, false alarms or false alarms will occur. The second is that the photoelectric smoke detector uses the scattering principle. The scattering intensity of light generates a detection signal. When there is black smoke, it is often not detected, resulting in false positives.
