Abstract
The utility model provides a fire alarm device comprising a single-chip microcomputer control module which is respectively connected with a temperature sensing module, an operating module, a temperature display module and an alarm display module. When a surrounding ambient temperature is out of range, the fire alarm device can automatically start the alarm, thus the fire alarm device has the advantages of no operations, simpleness and convenience.
Description
Technical field
The utility model belongs to the warning device technical field, relates to a kind of fire alarm installation.
Background technology
Existing it is more and more important that fire alarm becomes nowadays along with the increase of skyscraper, and the fire alarm installation in using at present is sensitive inadequately to the induction of environment temperature, thereby lower to the judgement degree of accuracy of fire.
Summary of the invention
The purpose of the utility model provides a kind of fire alarm installation, has solved the low problem of fire alarm precision that exists in the prior art.
The technical scheme that the utility model adopted is to comprise the single chip control module that is connected with temperature sense module, operational module, temperature display module and alarm indication module respectively.
The beneficial effect of a kind of fire alarm installation of the utility model is that after ambient temperature went beyond the scope, fire alarm installation can start automatically reported to the police, and need not simple to operation.
Description of drawings
Fig. 1 is a kind of fire alarm installation structural representation of the utility model.
Among the figure, 1. temperature sense module, 2. single chip control module, 3. operational module, 4. alarm indication module, 5. temperature display module.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
A kind of fire alarm installation structure of the utility model is as shown in Figure 1, comprises the single chip control module that is connected with temperature sense module, operational module, temperature display module and alarm indication module respectively.
A kind of fire alarm installation of the utility model; Single chip control module 2 adopts AT89S51, and thermometric sensing module 1 uses DS18B20, and eight of temperature display module 5 usefulness are total to anode LED charactron and transmit data with serial ports; The realization temperature shows; And the upper limit of this unit temp can be passed through operational module 3 adjustment, prescribes a time limit when temperature surpasses going up of setting, and alarm indication module 4 starts to report to the police.
A kind of fire alarm installation of the utility model, during use, operational module 3 can start alarm indication module 4 after giving limit value of single chip control module 2 inputs after temperature sense module 1 is sensed environment temperature to exceed limit value, report to the police.
