Abstract
The invention discloses a speech digital network fire alarm design system based on a single chip, wherein an AT89C51 single chip is used, an integrated temperature sensor AD590 and a gas sensor TGS202 are selected as the sensitive elements, and a speech digital network alarm applicable to the fire alarm of a small institute is developed by using a multi-sensor information fusion technology. The alarm hardware consists of a temperature smoke signal acquisition module, an audible and visual alarm module, the a single chip and a Modem communication module. The sudden change of the indoor smoke (CO2, CO) and temperature can be alarmed (audible and visual alarm); in the case of hardware faults (such as sensor drop, damage of internal device and the like), a fault alarm can be sent; if a parameter is abnormal (for example, the smoke concentration is excessively great or the temperature is excessively high,), an abnormity alarm signal can be sent such that the operator on duty can handle the situation on site; if both the smoke and the temperature are abnormal, a fire disaster happens, a fire alarm is sent, and the fire information is reported to a fire command center. The system is safe and reliable and ensures low rate of false alarm. Moreover, the system has wide application prospect due to the small size, convenient operation and maintenance, low cost, and the like.
Description
Technical field
The present invention's design is based on single-chip microcomputer, and sensor relates to signal Processing, the ken of aspects such as computing machine.Be specially and use the AT89C51 single-chip microcomputer, select for use integrated temperature sensor AD590 and gas sensor TGS202 as sensitive element, utilize multi-sensor information fusion technology, exploitation can be used for the speech digital network alarm of small-sized unit fire alarm.
Background technology
The automatic fire alarm control system of China experienced grow out of nothing, from simple to the evolution of complexity, its intelligent degree is also more and more higher.At present the research and development that are used for bulk storage plant, market, senior office building, hotels and other places large-sized fire warning system are laid particular stress on more by domestic manufacturer, and they adopt concentrated area controlling alarm mode, and its system complex, cost are higher.And in small fireproof units such as residential neighborhoods, machine room, offices, a kind of single or area networking, cheap practical automatic fire detection-alarm device need be set, therefore, developing a kind of simple in structure, cheap speech digital network fire alarm is very important.
Summary of the invention
In order to find fire safety evaluating hidden danger as early as possible, patent of the present invention has designed and has a kind ofly designed based on the single-chip microcomputer speech digital network fire alarm.
Technical scheme used in the present invention is: use the AT89C51 single-chip microcomputer, select for use integrated temperature sensor AD590 and gas sensor TGS202 as sensitive element, utilize multi-sensor information fusion technology, exploitation can be used for the speech digital network alarm of small-sized unit fire alarm.
Ensuing work also is two of committed step of the present invention, is exactly the composition of each module.Alarm hardware is made up of temperature smoke signal acquisition module, sound and light alarm module and single-chip microcomputer and Modem communication module.
The beneficial effect that the present invention compares with background technology is, this apparatus structure is simple, cheap, and specially at small fireproof units such as residential neighborhoods, machine room, offices, it is a kind of speech digital network fire alarm that is used for small fireproof unit, can to indoor smog (CO2, CO) and temperature jump report to the police (sound and light alarm); If hardware fault (losing damage of internal device etc. as sensor) can be sent fault alarm; If have only a kind of parameter unusual (as smokescope excessive or temperature is higher) to occur, can send the abnormal alarm signal, make the operator on duty arrive site disposal; If smog and temperature occur unusually simultaneously, then explanation has fire, sends alarm of fire, and in time fire information is reported FCC.Native system is safe and reliable, and rate of false alarm is low.And because little, the convenient operating maintenance of its volume, with low cost etc., have broad application prospects.

Specific implementation method
As shown in Figure 2, alarm hardware is made up of temperature smoke signal acquisition module, sound and light alarm module and single-chip microcomputer and Modem communication module.Wherein sensor (comprising cigarette sense and temperature sense) is converted into electric signal with non-electrical signals such as scene temperature, smog; Signal conditioning circuit is nursed one's health (amplifications, filtering etc.) with the electric signal of sensor output, makes it to satisfy the A/D change-over circuit, finishes the conversion to digital signal of simulating signal that temperature sensor and smoke transducer are exported.The sound and light alarm module is made up of single-chip microcomputer and warning circuit, realizes different sound and light alarm (abnormal alarm, fault alarm, fire alarm) functions by Single-chip Controlling.Single-chip microcomputer and Modem communication module are made up of single-chip microcomputer, GM16C550 serial port extended chip and RS232 level shifting circuit, realize alarm communicating by letter through Modem and FCC.So just constituted a SCM Based speech digital network fire alarm system, can to indoor smog (CO2, CO) and temperature jump report to the police (sound and light alarm).If hardware fault (losing damage of internal device etc. as sensor) can be sent fault alarm; If have only a kind of parameter unusual (as smokescope excessive or temperature is higher) to occur, can send the abnormal alarm signal, make the operator on duty arrive site disposal; If smog and temperature occur unusually simultaneously, then explanation has fire, sends alarm of fire, and in time fire information is reported FCC.
