Description
Technical field
The utility model belongs to field of security technology more particularly to a kind of alarm.
Background technique
Due to the security against fire consciousness of most people be not also it is very strong, few people periodically go the function of detection alarm to be
No is that normally, especially home for destitute, old residential block etc., the special populations in these places do not have condition to remove periodic detection cigarette
Whether the function of feeling product is normal, once fire occurs, even if alarm can detecte fire, but since the sounding of alarm fills
Functional fault is set, alarm loses audible alarm instruction function, and due pre-alarm system loses warning function originally,
It makes one to find and handle in time fire, loses the chance adopted an effective measure in the first time that fire occurs, to rescue
More difficulties are brought, causes fire disaster accident to occur, has also aggravated the severity of fire incident.
In addition, security against fire is realized in stronger scene, in order to ensure alarm work is normal, special detection people is had
Member periodically goes up gate test, but needs to expend a large amount of human costs.
Utility model content
The utility model embodiment provides a kind of alarm, it is intended to which the sounding device functional fault for solving alarm can not be certainly
The problem of dynamic detection.
The utility model embodiment is achieved in that a kind of alarm, comprising:

For detecting the sounding device to the detection signal device of the feedback of the warning trigger signal；
For sentencing to sounding device transmission warning trigger signal, and according to the testing result of the detection signal device
The whether faulty MCU of disconnected sounding device.
Further, the detection signal device is sound pick-up or microphone.
Further, the alarm further includes warning light, is mentioned for issuing light warning when breaking down or fire
Show.
Further, the alarm further includes detection key, for detecting failure manually.
Further, the alarm further includes wireless module, for sending fault message to specified platform.
Further, the wireless module is Zigbee submodule, Zwave submodule or Wi-Fi submodule.
Further, the specified platform is the one or more terminals bound in advance.
Further, the alarm further includes sensor for detecting smokescope and provides electric energy to alarm
Power supply, the sensor are connected with MCU.
The utility model embodiment has the following beneficial effects: that the utility model embodiment is sent out by MCU to sounding device
Warning trigger signal is sent, then issues alarm sound after receiving warning trigger signal by sounding device, then detected by detection signal device
Sounding device is finally judged the feedback of the warning trigger signal by MCU according to the testing result of the detection signal device
Whether sounding device is faulty, after confirming failure, issues fault alarm prompt, realizes the automatic inspection of the sounding device of alarm
It surveys, so that maintenance personal is found and is handled in time to field maintenance, avoid when fire occurs since sounding device failure can not
The problem of issuing alarm in time allows one to find and handle fire in time, reduces and lose caused by fire, and without sending work
Personnel also save manpower testing cost to on-site test.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of one embodiment of alarm of the utility model；
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Due to existing alarm, not to the automatic detection device of sounding device, in the case of fire, break down
Sounding device cannot issue alarm signal in time, make one to find and handle in time fire, aggravate the seriousness of fire incident,
The utility model embodiment carries out periodic detection to sounding device by increasing detection signal device, issues report after confirming failure
It is alert, it realizes the automatic detection of the sounding device of alarm, so that maintenance personal is found and is handled in time to field maintenance, avoid
Since sounding device failure can not issue the problem of alarm in time when fire occurs, allow one to find and handle fire in time,
Reduce and lost caused by fire, and without sending staff to on-site test, also saving manpower testing cost.
As shown in Figure 1, the utility model embodiment provides a kind of alarm, comprising:
For receiving the sounding device 1 for issuing alarm sound after warning trigger signal；
For detecting sounding device 1 to the detection signal device 2 of the feedback of warning trigger signal；
For sending warning trigger signal, and the testing result according to the detection signal device 2 to the sounding device 1
Judge the whether faulty MCU3 of sounding device (Microcontroller Unit, microprocessing unit).
Sounding device 1 is buzzer or loudspeaker etc., for issuing alarm sound.
Conventional alarm is all periodically to be acquired air signal by MCU3, to judge whether current environment is fire
Calamity, when having fire or battery low pressure or sensor failure occur, alarm provides fire alarm, low pressure or sensor
The signals such as failure.When these situations are all in normal situation, alarm will enter standby dormant state, to save electricity.
After reaching the time cycle of detection, MCU is waken up again, the detection operation before repeating.
In the utility model embodiment, while MCU3 is periodically acquired air signal, such as to sounding device 1
Buzzer sends warning trigger signal, if sounding device is normal, detection signal device 2 can detect 1 pair of sounding device alarm
The feedback of trigger signal, alarm can be automatically into dormant states, if to can't detect sounding device 1 right for detection signal device 2
The feedback of warning trigger signal, MCU then judge that sounding device is faulty.
The utility model embodiment sends warning trigger signal to sounding device by MCU, then receives report by sounding device
Issue alarm sound after alert trigger signal, then by detection signal device detection sounding device to the feedback of the warning trigger signal,
Finally judge whether sounding device is faulty according to the testing result of the detection signal device by MCU, after confirming failure, issues
Fault alarm prompt, realizes the automatic detection of the sounding device of alarm, so that maintenance personal is found in time and arrives field maintenance
Processing avoids and the problem of can not issuing alarm in time due to sounding device failure when fire occurs, allows one to find in time
And fire is handled, reduce and lost caused by fire, and without sending staff to on-site test, also saving manpower testing cost.
In one alternative embodiment of the utility model, the detection signal device 2 is sound pick-up or microphone.Sound pick-up
Or microphone can receive sounding device 1 and be sent to MCU3 to the feedback of warning trigger signal, and by feedback result.
In one alternative embodiment of the utility model, the alarm further includes warning light 4, for breaking down or
Light warning prompt is issued when fire.Warning light quick flashing 2 times or other numbers, it is faulty can to issue at any time sounding device 1
Warning, convenient for passing by pedestrian's discovery of alarm.
In one alternative embodiment of the utility model, the alarm further includes detection key 5, for detecting event manually
Barrier.When staff checks at the scene, after Pen-down detection key 5, if warning light quick flashing 2 times or other numbers, work is prompted
