Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0021] combine figure 1 As shown, a toxic gas detection and alarm system includes an alarm prompt unit, an LED alarm light, a buzzer, a touch switch, a toxic gas detector, a signal acquisition and processing device, and a terminal instrument.

[0022] Touch switches are normally closed switches.

[0023] 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.

[0024] 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.

[0025] Toxic gas detectors o...

Description

technical field [0001] The invention relates to a toxic gas detection and alarm system and method. Background technique [0002] A general toxic gas detection system is a system used to detect toxic gas and issue 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 toxic gas alarm system utilizes sound alarm, but when the sound alarm breaks down or fails to work, the entire toxic gas alarm system will lose its effect. The invention relates to a toxic gas detection and alarm system and method. When a toxic gas detector detects a toxic gas, 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. , It is of great signific...
