Fire early warning device

Abstract

The invention relates to a fire early warning device which comprises a smoke sensor, an amplifier, an A / D converter, a controller, a short message sending module and a buzzer. The smoke sensor is installed at a fire monitoring spot, connected with the amplifier and used for converting a smoke signal into an electric signal. The amplifier is connected with the A / D converter and used for amplifying the electric signal output by the smoke sensor. The A / D converter is an analog-digital converter circuit and is connected with the controller and used for converting an analog signal outputted by the amplifier into a digital signal and transmitting the digital signal to the controller which is respectively connected with the short message sending module and the buzzer. The short message sending module is a short message wireless sending module and used for sending a warning short message to a designated user mobile phone. The buzzer is an audio warning device. The fire early warning device has the advantages of being capable of effectively warning a fire in advance and facilitating reduction of fire threats in life and production.

Description

technical field [0001] The invention relates to an alarm, in particular to a fire early warning device. Background technique [0002] At present, fires are frequent and have brought a huge threat to people's production and life. How to effectively prevent fires has become a major problem that people are facing. At present, many researchers are conducting research on fire prevention, but they mainly focus on fire prevention. In terms of sound or photosensitive prompts, in sparsely populated places, no one will hear the siren or flashing signal, so the effect on fire warning is greatly reduced. Therefore, how to warn fire more efficiently has become a new topic of fire prevention. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide a fire warning device. [0004] In order to achieve the above object, the fire early warning device provided by the present invention includes: smoke sensor, amplifier, A / D c...
