In one particular embodiment of the present invention, the communication unit includes A7139 communication module.
In one particular embodiment of the present invention, the main control unit is also connected with fault detection unit, the failure
Detection unit includes comparator.
In one particular embodiment of the present invention, the single-chip microcontroller is built-in with WatchDog Timer and converter.
In order to facilitate above-mentioned technical proposal of the invention is understood, below by way of specifically used mode to above-mentioned skill of the invention
Art scheme is described in detail.
433MHz is that the transmitting for exempting from application in China receives frequency range.With transmission range is long, penetration capacity is strong, networking is clever
The advantages that living, low in energy consumption.And fire acousto-optic alarm is the major product of fire protection warning, it is very widely used.Traditional code type
The key technology of acousto-optic is sound, light alarm and Communication Control.When 433MHz mechanics of communication and conventional fire acoustooptic alarm are mutually tied
When conjunction, just embodied with advantage the characteristics of product
Fire acousto-optic alarm of the present invention, comprising: main control unit, sound control unit, flash control unit, communication are single
Member, battery and fault detection unit.
Main control unit includes single-chip microcontroller, is responsible for the control of entire fire acousto-optic alarm, makes the coordination work of modules
Make.Wherein sound control unit by PWM mode realize so that modified tone the period at 2.6s ± 0.1s, 3 meters sound pressure level in 95dB
(A weighted) left and right.Sound control unit is also added into current-limiting circuit, least in power-consuming in the case that guarantee meets sound pressure level.And
Sound pressure level is influenced whether will not be because of the electricity abundance of battery.Flash control unit is for periodically lighting two pole of high-brightness luminous
Pipe, the light for guaranteeing that fire acousto-optic alarm issues under 100lx ~ 150lx ambient light is high-visible at 25m, is added simultaneously
Constant-current circuit.Communication unit is worked using mature A7139 communication module, the module in the ISM band of 433MHz.The module
Small in size, power consumption is extremely low, normally receives electric current 3.8mA under mode, electric current 24mA under sending mode.With sleep pattern, electric current
It can be reduced to 1.5uA, which supports carrier wave to wake up.
Fire acousto-optic alarm needs work in interactive mode, receives the starting of fire-fighting host at any time, ceases and desist order.Simultaneously
Fire acousto-optic alarm can send online information and cell voltage and give fire-fighting host.When normal work, single-chip microcontroller and communication unit
It all works in suspend mode.Enter reception pattern after communication unit detects carrier signal, then communication unit passes through monolithic
The external interrupt pin of machine wakes up single-chip microcontroller, and single-chip microcontroller enters normal mode of operation immediately.Single-chip microcontroller is received after waking up by SPI
To valid data and after verifying correctly, the corresponding command, starting or stopping sound control unit, flash control unit are responded.With
Communication unit reenters sleep pattern afterwards.And single-chip microcontroller is due to sound control unit to be controlled, flash control unit, no longer into
Enter low-power consumption mode.After fire-fighting host wirelessly stops fire acousto-optic alarm, single-chip microcontroller and communication unit into
Enter low-power consumption mode.In addition, single-chip microcontroller can periodically wake up oneself by WatchDog Timer, subsequent single-chip microcontroller wakes up communication
Unit, makes communication unit enter sending mode, and battery information is sent to host in a manner of online heartbeat message by single-chip microcontroller.
The working principle of sound control unit: single-chip microcontroller issues the square wave of 1K ~ 2KHz, and square wave frequency sinusoidally becomes
Change.It is issued in the circulation of the threshold of audibility range periodically of people.Sound control unit circuit is to induction charging, inductive energy storage, simultaneously
Current-limiting circuit controls charging current in 60mA.Inductance discharges in discharge cycle to audio device (loudspeaker).Loudspeaker sending is played
The alarm sound of warning function.
The working principle of fault detection unit: single-chip microcontroller passes through in fault detection unit after being waken up by WatchDog Timer
Comparator detects cell voltage, and when cell voltage is lower than fault alarm threshold value, single-chip microcontroller obtains voltage letter by converter
Number, it is filtered, after obtaining exact failure signal, single-chip microcontroller wakes up communication unit, and fault message and cell voltage are sent out
Give fire-fighting host.It is sent completely rear single-chip microcontroller and communication unit enters low-power consumption mode.
In conclusion by means of above-mentioned technical proposal of the invention, it is cumbersome to solve wired acoustooptic alarm wiring, at high cost
The problem of, give full play to 433MHz wireless telecommunications in the application of fire alarm industry, it is low in energy consumption.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
