Abstract
The invention discloses an automatic fire alarm device. The automatic fire alarm device is mainly composed of a sensor portion, a data processing center, a sound and light alarm circuit and a vibration alarm circuit; the sensor portion comprises two components which are a slide rheostat and an A/D converter; the data processing center comprises a single chip microcomputer AT89S51 and a nixie tube; the working process of the whole automatic fire alarm device comprises the steps that a smoke concentration sensor senses changes of the concentration of smoke and produces analog signals, the analog signals are converted into digital signals through a converting circuit, the single chip microcomputer carries out analysis and judgment according to a preprogram after receiving the digital signals, on one hand, the concentration of the smoke can be displayed in real time, and on the other hand, sound, lamplight and vibration alarms can be produced. The automatic fire alarm device can give the vibration alarm while giving the sound alarm and the lamplight alarm, the characteristic that the deaf are sensitive to the physical phenomenon of vibration is used fully, and the automatic fire alarm device is simple in structure, low in cost, easy to produce and install, and convenient to debug and maintain.
Description
Technical field
The present invention relates to a kind of automatic fire alarm, especially a kind of automatic fire alarm with vibrations warning function.
Background technology
Fire, is bringing human foods, and light, when warm and civilization and progress, also can cause it out of hand and bring serious harm to people's lives and properties and social development because of a variety of causes.Nowadays, the combustible disaster that out of control burning causes on time or space, namely our usually said fire, has become one of topmost disaster threatening social development and public safety gradually.According to incompletely statistics, China is 2.5 hundred million yuan of the seventies fire average loss in last century less thaies, and the average loss that the eighties fire causes has approached 3.2 hundred million yuan.And enter the nineties, and particularly since nineteen ninety-three, its direct economic loss causing has risen violently average annual tens00000000 yuan, and average annual death toll exceedes 2,000 people.And fire accidents accident is of common occurrence, cause positive severe social influence.
Cruel and severe fact proved, be accompanied by economical and social development, growing with each passing day of the wealth of society, fire brings physical environment, society and the mankind's various harm constantly increase, its breaking-up be not only the ecology harmony of environment, civil order stable and united, the direct or indirect security of the lives and property that is threatening the mankind especially, has caused wound that cannot be floating even to people's soul.Just because of this, people have little by little recognized and have established and improve scientific and effective fire hazard monitoring early warning mechanism now, do energetically necessity and the importance of fire-fighting link work well.
Since 21 century, electronic product in people's productive life in occupation of consequence more and more, becoming the necessity in people's life.But because product sole mass and the fire that uses operational issue to cause are also more and more.Therefore, intelligentized fire-alarm arises at the historic moment, and formally steps into people's the visual field.Present high-tech fire-alarm has not been traditional panalarm, but has incorporated the product of each field scientific knowledges such as sensor application, automatic control technology, electronic technology, computer technology.Believe and be accompanied by scientific and technological development and progress, no matter fire-alarm is in function, and price still all will have more marvelous development in practicality.On market, the type of alarm of comparatively common automatic fire alarm is generally sound and light now.In China, national policy is to encourage the disabled persons such as deaf-mute to go work to factory and enterprise unit.And the working environment of these factories is often accompanied by many hazards such as high noisy and certain disaster hidden-trouble.But that disabled person's self feature and environmental factor have determined is existing only with the fire-alarm of sound and light warning, its working effect can't be desirable.
Summary of the invention
The present invention is the weak point existing in above-mentioned prior art for avoiding, and a kind of automatic fire alarm is provided, especially a kind of automatic fire alarm with vibrations warning function.
The present invention be technical solution problem by the following technical solutions.
Mainly, by Sensor section, data processing centre (DPC), sound light alarming circuit, vibrations warning circuit four parts form; Described Sensor section comprises two components and parts: one is slide rheostat, and the 2nd, A/D converter; Described data processing centre (DPC) comprises single chip computer AT 89S51 and a charactron; The workflow of whole system is that smokescope sensor is experienced the variation of smokescope and produced simulating signal, simulating signal is transformed into digital signal through change-over circuit, single-chip microcomputer is analyzed judgement according to preset program after receiving digital signal, can show in real time smokescope on the one hand, produce on the other hand sound, light and vibrations are reported to the police.
The design feature of automatic fire alarm of the present invention is also:
Described rheostat, its function is experienced the variation of smokescope, and produces corresponding electric signal according to the difference of concentration value.
Described A/D converter, inputs single-chip microcomputer after making simulating signal that smoke transducer detects be converted into digital signal.
Described single chip computer AT 89S51, the signal that will send over smoke transducer on the one hand receives, and will make calculation process to this signal on the other hand, to the corresponding actions of subsequent conditioning circuit is controlled.
Described charactron, i.e. digital pipe display circuit, can show smokescope in real time
Described vibrations warning circuit, is mainly made up of wiring board, motor and eccentric wheel.
Compared with the prior art, beneficial effect of the present invention is embodied in:
A kind of automatic fire alarm of the present invention can send vibrations and report to the police in sound and light warning, take full advantage of deaf-mute to shaking the feature of this physical phenomenon sensitivity, and this alarm is simple in structure, with low cost, be easy to produce and install, the advantage of being convenient to debugging and safeguarding.
