Abstract
The utility model discloses a fiber grating fire detection system, belongs to the field of fire detection, and aims at solving the problems that the existing fire detection system needs real-time monitoring by manpower and is high in work intensity. The fiber grating fire detection system is characterized by comprising a light source, a coupler, an fiber grating sensor, a fiber grating demodulation module, a central processing module and a general packet radio service (GPRS) short message service (SMS) alarm module, wherein the light source emits optical signals which enter the fiber grating sensor through the coupler, reflected optical signals of the fiber grating sensor enter the fiber grating demodulation module through the coupler and are sent to the central processing module after photoelectric conversion and processing by the fiber grating demodulation module, and the central processing module sends detection information through the GPRS SMS alarm module. The fiber grating fire detection system can be used for replacing the existing fire detection system.
Description
Technical field
The utility model relates to fire detecting system, relates in particular to the optic fibre fire detection system.
Background technology
At present, optical fiber grating temperature-measuring system,, fast response time high due to its temperature measurement accuracy, can work and a bit be widely used in the temperature monitoring in the fields such as transformer station's High-low voltage switch cabinet, cable splice, petroleum and petrochemical industry storage tank with the rugged surroundings of electromagnetic environment complexity etc., with the disaster hidden-trouble that timely discovery exists, accomplish to prevent trouble before it happens.
Existing fiber grating fire detecting system, when it detects abnormal temperature by fiber-optic grating sensor, generally eject relevant warning message by upper computer software, this just requires and must just can guarantee in time find warning message and process by 24 hours Attended modes, has greatly increased the O﹠M personnel's of system working strength.
The utility model content
In view of this, be necessary for the problems referred to above, a kind of fiber grating fire detecting system be provided, the utility model by the following technical solutions:
A kind of fiber grating fire detecting system, comprise light source, coupling mechanism, fiber-optic grating sensor, fiber grating demodulation module, central processing module and GPRS short message alarm module, described source emissioning light signal incides in described fiber-optic grating sensor through coupling mechanism, and the reflected light signal of described fiber-optic grating sensor incides described fiber grating demodulation module through described coupling mechanism; Deliver to described central processing module through described fiber grating demodulation module opto-electronic conversion with after processing, described central processing module sends detection information by described GPRS short message alarm module.
In the fiber grating fire detecting system of the utility model scheme, described light source is wideband light source.
In the fiber grating fire detecting system of the utility model scheme, described central processing module sends the temperature information note on specified mobile phone number by described GPRS short message alarm module.
In the fiber grating fire detecting system of the utility model scheme, can described specified mobile phone number, alarm threshold value be set by described central processing module.
In the fiber grating fire detecting system of the utility model scheme, described detection information comprises time of fire alarming, type of alarm, alarm temperature, alert locations.
In the fiber grating fire detecting system of the utility model scheme, described coupling mechanism is the 1X2 coupling mechanism.
The beneficial effects of the utility model are: connected a GPRS short message alarm module at central processing module one end, when detecting abnormal temperature by fiber-optic grating sensor, central processing module sends on the phone number that sets in advance by the alarming short message that the GRPS short message alarm module will comprise time of fire alarming, type of alarm, alarm temperature and alert locations; So just need not 24 hours Attended modes and just can guarantee in time find warning message and process, greatly reduce the O﹠M personnel's of system working strength.
Description of drawings
Fig. 1 is fiber grating fire detecting system schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further detailed.
In Fig. 1, wideband light source has been launched a wide spectrum optical, incide in fiber-optic grating sensor through the 1X2 coupling mechanism, fiber-optic grating sensor can reflect the light signal of specific wavelength, the light signal that reflects incides the fiber grating demodulation module through the 1X2 coupling mechanism, can obtain through the demodulation of fiber grating demodulation module the centre wavelength value that fiber-optic grating sensor reflects light signal, again this wavelength value is delivered in central processing module, can be obtained the fiber-optic grating sensor measured temperature as calculated; Send the detection information note by the GPRS short message alarm module on the phone number that pre-sets; Greater than setting alarm threshold value, namely send alarming short message by the GPRS short message alarm module on the phone number that pre-sets when temperature value; Can also specified mobile phone number, alarm threshold value be set by central processing module; Detection information comprises time of fire alarming, type of alarm, alarm temperature, alert locations, conveniently trace point is carried out track and localization.
So just need not 24 hours Attended modes and just can guarantee in time find warning message and process, greatly reduce the O﹠M personnel's of system working strength, and set phone number, alarm threshold value conveniently, guarantee that personal scheduling is flexible.
The above embodiment has only expressed embodiment of the present utility model, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
