In addition the present invention discloses a kind of Multifunction safety siren alarm system, including above-mentioned functional safety alarm,
And first wireless communication module 17, concentrator 18, the second wireless communication module 19, cloud server 20 and terminal device 21,
Wherein:
The concentrator 18 passes through second wireless communication module 19 and the cloud server 20 and terminal device 21
Be wirelessly connected, for by first wireless communication module 17 periodically read the smokescope recorded in the single-chip microcontroller 15,
Fire Radiation intensity, the numerical value of temperature and/or concentration of toxic gases and formation warning message and be respectively sent to the cloud
Hold server 20 and terminal device 21.In the present embodiment, the concentrator 18 is equipped with RTC real-time clock, when for recording real-time
Between.Preferably, the terminal device 21 uses host computer, notebook computer, tablet computer or smart phone, is convenient for staff
It checks and safeguards in time.
Preferably, first wireless communication module 17 uses 433M short-range communication module, 433M short haul connection mould
The communication distance theoretical value of block is 800 meters or so, and in practice, due to various interference, measured distance is 300 meters, is had centainly
Penetration capacity can satisfy the alarm demand of common buildings.Second wireless communication module 19 uses GPRS wireless telecommunications mould
Block or WiFi wireless communication module.
Concrete operating principle:
First after system electrification, Multifunction safety siren can complete self-checking function, confirm system components operating status
Well, the first interface of default then can be shown on concentrator 18, can show real-time clock (being realized by RTC clock module) above.
Meanwhile indicating that the morse signal light of communication can flash on concentrator 18, the power supply indicator powered on can also flash, and be carried out with this
Prompt.After alarm receives alarm signal, the LED light 6 on alarm shell upper layer 1 can flash, while on alarm
Buzzer 16 can sound.Later, alarm passes through the first wireless communication module (433M short-range communication module) for warning message
It is sent to concentrator 18 nearby.After concentrator 18 receives the alarm signal from alarm, first inside concentrator 18
Buzzer can also sound simultaneously, secondly, the LED light 6 on alarm can light (be under default conditions extinguish), later, collection
Warning message is transmitted to cloud server 20 together by GPRS wireless communication module by the warning message that middle device 18 can will receive
When be sent in remote security monitor terminal equipment 21 (host computer).
After staff in monitoring room sees alarm signal on host computer, fire fighter can be notified to come, wait disappear
Anti- personnel rush to the site of the accident, after completing fire extinguishing, need to make concentrator 18 operation that one is eliminated alarm and (pass through concentrator
L touch display screen on 18 is operated).After concentrator 18 releases alarm, it can be issued simultaneously to alarm and host computer
Instruction carries out reset operation automatically, closes the LED light 6 and buzzer of alarm after alarm receives the instruction of " eliminating alarm "
16；After cloud server 20 receives instruction, it can also send one and instruct to host computer, in this way, the fire fighting monitoring room of distant place
Staff can grasp the job schedule of live fire-fighting in real time.
It is above-mentioned specific logic putting in order is as shown in Figure 4: to will do it self-check, the content packet of inspection after system electrification first
Include, the electric power detection of battery, circuit system whether failure, sensor function whether effectively (external environment under safety condition, and
There is no alarm signal).If encountering one of functional fault is directly entered alarm link, if not provided, system will start it is low
Power consumption function, into standby mode.In the standby state, intermediate to have by some internal or external interference, it is receiving
To after these interference signals, system will do it a judgement, such as: toxic sensor can receive water vapour, and water vapour
Again not in alarm range, the resistance that we can take toxic gas sensor 12 to send out, according to module
Resistance value difference judges it is which kind of steam (gas).Later, smoke sensor device 9, flame sensor 10, temperature sensor 11 and have
A trigger signal can be all exported after any one triggered as normal of poison gas body sensor 12 4, system enters alarm condition.
In the present embodiment, the Multifunction safety siren has very strong popularization and compatibility, and mounting means is got rid of
The limitation of traditional cabling layout, while on-line communication can be carried out between the Multifunction safety siren on periphery, but when work
It does not interfere with each other again.Therefore the diffusion of cobweb formula can be formed, and the Multifunction safety siren on periphery can will be collected into
Information concentrate and be emitted to the concentrator in bosom.In routine use, new user can install quickly, and old user can be with
Carry out convenient and fast system upgrade, it is only necessary to which the communication protocol that a default is arranged in the information of former concentrator can be with new system
It carries out online.After having above functions, so that it may will original freestanding alarm and small-scale alarm system progress ten thousand
Object interconnection, to finally construct " urban fire control security community ".
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
