Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] combine figure 1 As shown, a smoke detection and alarm system includes an alarm prompt unit, an LED alarm light, a buzzer, a touch switch, a smoke detector, a signal acquisition and processing device, and a terminal instrument.

[0021] Touch switches are normally closed switches.

[0022] The contacts of the touch switch are installed at the easy-to-touch position on the wall 1.5 meters from the ground, and the contacts of the touch switch are fluorescent contacts.

[0023] The touch switch is connected with the signal acquisition and processing device, and is used to control the on-off of the indoor lighting power supply. The specific control process is to turn on the indoor lighting device again by touching the touch switch on the wall when evacuating, which is convenient for exiting the scene.

[0024] Smoke detectors operate when ...

Abstract

The invention discloses a smoke sensing detection alarm system and method. The smoke sensing detection alarm system includes an alarm prompting unit, an LED alarm light, a buzzer, a touch switch, a smoke sensing detector, an alarm warning unit, a signal acquisition and processing device, and a terminal instrument, wherein the touch switch is connected with the signal acquisition and processing device; the touch switch is used for controlling on and off of a power supply of an indoor lighting device; the smoke sensing detector is used for detecting indoor smoke, and sending a signal to the signal acquisition and processing device; the smoke sensing detector is connected with the LED alarm light and the buzzer; the signal acquisition and processing device is connected with the terminal instrument; the signal acquisition and processing device is used for amplifying and converting the received signal, and transmitting the processed signal to the terminal instrument for display; and the terminal instrument is connected with the alarm warning unit, and the terminal instrument is used to control the alarm warning unit to give an alarm. The smoke sensing detection alarm system is safe, reliable, convenient and practical.

Description

technical field [0001] The invention relates to a smoke detection and alarm system and method. Background technique [0002] The general smoke detection system is a system used to detect the smoke concentration in the early stage of the fire scene and give an alarm. This system is applicable to a wide range of places and has extremely high use value. It is suitable for various environments such as indoors and outdoors. It can effectively send an alarm to the on-site personnel and prompt the on-site personnel to evacuate. Generally, the smoke alarm system uses sound alarm, but when the sound alarm fails or fails to work, the entire smoke alarm system will lose its effect. The invention relates to a smoke detection and alarm system and method. When the smoke detector detects smoke, it can send out sound and light signals at the same time, prompting the on-site personnel to leave quickly, ensuring that the emergency response is carried out effectively and on time, and reducing...
