Description
Technical field
The utility model relates to the technical field of detection, especially relates to a kind of fire detection alarm.
Background technology
At present, image-type fire detector is divided into single-lens image-type fire detector and twin-lens image-type fire detector.
For single-lens image-type fire detector, a colour TV camera only can be installed or a thermal camera is only installed after a monitoring camera lens, the product of a colour TV camera is installed separately, because colour TV camera operates mainly in visible light wave range, vision signal does not have obvious heat signal, so mainly depend on mode of motion aspect video identification, identify flame, rate of false alarm is very high.And the image-type fire detector that a thermal camera is installed is owing to can only catching and export infrared signal, making vision signal is mainly that the mode of black white image or TEMPERATURE SPECTROSCOPY image is shown to client, user's visual effect is not good, affects client for the judgement of point of origin position.
Defect based on above product, some producers develop the image-type fire detector product of twin-lens twin camera, in the hope of when meeting fire alarm accuracy rate, and can provide good visual effect to user.But because two video cameras have respectively independently monitoring camera, and because two video camera installation sites necessarily there are differences, make the guarded region of two video cameras can have obvious displacement difference, obviously have influence on the accuracy of fire locating, the search coverage of fire also can have blind area.
Utility model content
The purpose of this utility model is to design a kind of fire detection alarm, addresses the above problem.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A fire detection alarm, comprises Amici prism, monitoring camera lens, colour TV camera, near infrared video camera and two video processing equipment; The porch of described Amici prism is provided with described monitoring camera lens; The outlet of described Amici prism comprises the first outlet and the second outlet; Described the first exit is provided with described colour TV camera; Described the second exit is provided with described near infrared video camera; Described colour TV camera is all connected with described pair of video processing equipment with described near infrared video camera.
Preferably, on described pair of video processing equipment, be connected with power interface plate and warning device.
Be more preferably, on described pair of video processing equipment, be also connected with one or more in storer, communication module, pilot lamp, power supervisor, temperature sensor and well heater.
Be more preferably, described communication module comprises ethernet transceiver and/or RS485 transceiver.
Be more preferably, described colour TV camera is colored veneer video camera; Described near infrared video camera is near infrared veneer video camera; Described pair of video processing equipment is DSP two-way video-signal disposable plates.
Be more preferably, described infrared veneer video camera adopts the infrared high-pass filter of 950nm.
Be more preferably, described DSP two-way video-signal disposable plates is TMS320DM642 disposable plates.
Be more preferably, described Amici prism is optical glass material.
The beneficial effects of the utility model can be summarized as follows:
The multiplexing monitoring camera of two video cameras that the utility model provides is realized the detector of colored and infrared image complex probe fire, employing monitoring camera is found a view, use Amici prism Jiang Yi road light signal to be divided into the optical texture that two-way is given respectively two video cameras, the guarded region that has solved two video cameras can have other defect of obvious displacement difference, and in manually carrying out the analysis deterministic process of fire, combine two kinds of detection modes of colour TV camera and near infrared video camera, improved the accuracy of fire locating, improved the reliability of reporting to the police, filled up the blank of similar products at home and abroad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
