Description
Technical field
The utility model relates to a kind of fire alarm installation, especially a kind of fire alarm data message and scene of fire video information one transmitting device.
Background technology
In fire monitoring system, video data needs in real time outwards transmission, is used for realizing on-the-spot real-time monitoring.Chinese utility model patent CN203812070U discloses a kind of Room Power ambient video total management system, achieves the video data real-time Transmission of guarded region.But in scene of fire, data transmission cable can be subject to the impact of the external factor such as high temperature, building structure deformation.In order to improve the stability of data transmission, usually at the outer setting flame-retardant layer of cable, but this structure is when in the face of the collapsing of this body structure of buildings, effectively cannot keep the normal work of cable.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of fire alarm data message and scene of fire video information one transmitting device, improves the stability that data transmission device works in extreme circumstances.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
A kind of fire alarm data message and scene of fire video information one transmitting device, comprise fire sensor, camera and data collection host, fire sensor is connected with data collection host by data cable with camera, described data cable comprises fiber core, the arranged outside of fiber core has insulation course, the arranged outside of insulation course has conductive copper wire layer, the arranged outside of conductive copper wire layer has fire-retardant skin, be filled with heat-resistant resin layer between fire-retardant skin and insulation course, fire-retardant outer field inwall be evenly provided with several open circles stage bodies; The interface of data cable and fire sensor, camera and data collection host is provided with the metal interface of hyperboloid of one sheet shape, the first shell fragment is fixed with outside metal interface, first shell fragment is provided with groove, groove is connected with the second shell fragment, fire-retardant skin is fixed on the second shell fragment, is provided with sealing rubber strip in groove.
As preferably, described fire sensor and be also provided with flash memory register between camera and data collection host, flash memory register outer setting has thermally insulating housing.
As preferably, between described flash memory register and data collection host, adopt time-sharing multiplex anatomical connectivity.
The beneficial effect adopting technique scheme to bring is: the utility model, on the basis of conventional video data transmission system, improves the structure of cable, thus when running into the situation that buildings tentatively collapses, also can keep normal transfer function.First, original independent video cables of arranging and data cable are merged, fiber core is used for transmission video signal, and conductive copper wire floor is used for transmitting datagram number, and uses insulation course fiber core and conductive copper wire layer to be separated.Because fiber strength is low, can effectively protect fiber core at arranged outside conductive copper wire layer.Conductive copper wire layer wraps up by heat-resistant resin layer completely; when fire-retardant outer breakage; can protect the fiber core of conductive copper wire layer and inside thereof; in addition; when fire-retardant outer breakage, external high temperature acts on heat-resistant resin layer, and heat-resistant resin layer can soften gradually; make the protective seam that outside conductive copper wire layer, formation one is flexible, this effectively can prevent destroying fire-retardant outer field hard objects and destroy further heat-resistant resin layer.Data cable and metal interface resilient engagement; under the elastic deformation effect of the first shell fragment and the second shell fragment; data cable can produce relative displacement with metal interface, and this just can the extraneous drag force that is subject to of buffered data cable, improves fire-retardant outer field protective capability.When fire-retardant skin is subject to the effect of extraneous drag force, open circles stage body can improve and is interconnected power between fire-retardant skin and heat-resistant resin layer, not to be damaged but ambient temperature sharply raises, extraneous high temperature can carry out part transmission by fire-retardant skin to heat-resistant resin layer at fire-retardant skin in addition.When heat-resistant resin layer be heated occur softening time, the heat stable resin in open circles stage body provides filling power, can ensure that the surface of contact between heat-resistant resin layer and fire-retardant skin does not occur space.Data transmission and transmission of video can be integrated in single line cable and complete by the cable structure that the utility model improves, and simplify the structure of cable, improve the stability that cable works in extreme circumstances.The flash memory register installed additional can be arranged on the position near collection terminal, unloading is carried out to video and data-signal, this when data cable end damages, still can carry out provisional record to the situation of scene of fire, reduce the failure rate of whole device.Adopt time-sharing multiplex between flash memory register and data collection host, can number of cables be reduced, thus reduce failure rate.
