Embodiment
To describe the technology contents of the utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates attached drawing to be explained in detail.
Please refer to Fig.1 and Fig. 2, the utility model provide a kind of intelligent fire alarm bell, which can carry
For temperature detection and Smoke Detection, and alarm is produced when smokescope in detecting thermo-field thoery or air is exceeded, can be wide
The general fire protection warning applied to family, dormitory or workshop needs.
Referring to Fig. 1, the intelligent fire alarm bell includes power supply circuit 40, control circuit 10, detection circuit 20 and alarm
Circuit 30.
Wherein, power supply circuit 40 is electrically connected with detection circuit 20, control circuit 10 and warning circuit 30, for for its
Each circuit of connection provides working power.In the present embodiment, the power supply circuit 40 be DC24V storage battery, control circuit
Reduction voltage circuit is inside provided with, can be by DC24V power voltage step downs to 9V and 5V power supplys.The temperature in measurement wherein in detection circuit 20
The power input pin of sensor 201 and smoke sensor device 202 is connected to the output terminal of the 9V and 5V power supplys.
The detection circuit 20 is used to obtain temperature and smokescope in environment, for alarm decision provide data according to
According to.The warning circuit includes being used for the loudspeaker 301 for producing alarm sound, and for producing the alarm lamp group of alarm light
302, it is preferred that the lamp group includes the LED lamp bead of two or more different colours.The control circuit 10 respectively with detection circuit
And warning circuit connection, for being judged whether that fire occurs according to the environment temperature and smokescope that detect, and sending out
Warning circuit is triggered during calamity of lighting a fire and produces alarm signal (in the function of control circuit and the existing equipment for fire alarm
The function of control circuit is identical).Such as produced when smog (CO, CO2) concentration during environment temperature is more than 65 ° or air >=0.06%
Alarm signal.Certainly, in various embodiments, in order to adapt to different monitoring of environmental needs, wherein the temperature value alarmed
Or smokescope can, can be adjusted correspondingly as needed.
Existing fire alarm bell can only produce audible alarm, and must be connected to alarm controller use, and the intelligence
Fire alarm bell includes detection circuit and warning circuit, the information such as temperature and smog in detectable environment, when alert occurs
Alarm signal is produced by warning circuit, therefore other controllers need not be connected to and can be used alone, it is more convenient to use.
As shown in Fig. 2, in the present embodiment, detection circuit further comprises admission line, detected for collecting in environment
Air, the admission line includes exhaust fan, main pipeline and two or more lateral.Exhaust fan and smoke sensor device are set
