Embodiment Construction

[0027] First focus on introducing the design idea of ​​the present invention.

[0028] In order for the intelligent fire extinguisher of the present invention to extinguish fire quickly, accurately and reliably, its technical solution must solve two key technical problems: first, how to identify the flame; second, how to locate the fire source.

[0029] For the first key technical problem, the solution of the present invention is: two parameters are used to identify the flame, one is the flicker frequency of the flame; the other is the heat radiation value of the flame. How to measure these two parameters is described below.

[0030] After the flame signal collected by the sensor is low-pass filtered and voltage amplified, the high-frequency signal is filtered out, leaving a low-frequency signal reflecting the characteristics of the flame, which is shaped into a rectangular pulse signal and sent to the single-chip microcomputer I / O At the mouth, the flicker frequency of the fla...

Abstract

An intelligent extinguisher of the invention comprises a water sprayer and an electric control box which are connected through a multicore cable. The water sprayer comprises two parts of an upper machine body and a lower machine body. The upper machine body comprises a main water pipe, a horizontal stepping motor, a vertical stepping motor, etc. The lower machine body comprises a lower machine body, a water spraying nozzle seat, etc. More than one water spraying nozzle is installed on the water spraying nozzle seat. The right end of lower machine seat is installed with a horizontal searching sensor seat for installing a horizontal searching sensor and a vertical searching sensor seat for installing a vertical searching sensor. A hall switch base is installed in the upper machine body. A control system, a monitoring sensor, a warning system and a power supply device are installed in the electric control box. The core device of control system is a main single chip microcomputer. The warning system can alarm with two modes of voice and fire engine sound. The intelligent extinguisher of the invention has the advantages of accurate and reliable positioning to fire source; short time for searching the fire source, high speed of no more than 20 seconds from ignition to water spraying to the fire source; low cost and convenient installation.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and is an electromechanical integrated intelligent fire extinguisher which is hung on the roof and integrates sensing technology, electronic technology, and computer software and hardware technology. Background technique [0002] In today's information age, in order to improve the performance of fire extinguishers, computer technology must be used to make fire extinguishers intelligent. The so-called intelligent fire extinguisher should be based on computer software and hardware technology, which can automatically process fire information, automatically alarm, and automatically control fire detection, fire source location and directional fire extinguishing. [0003] Intelligent fire extinguishers or intelligent fire extinguishing devices have occurred on the market and relevant documents at present. These intelligent fire extinguishers or intelligent fire extinguishing devices ca...
