The infrared optical lens is connected with the detector which is connected with the front-end processing circuit. The infrared network camera also comprises a follow-up circuit. The input end of the follow-up circuit is connected with the output end of the front-end processing circuit. The output end of the follow-up circuit is connected with an Ethernet interface. Through employing the above structure, the infrared network camera provided by the utility model can compress and encode a detected image, and transmits the image to a monitoring center, thereby achieving remote control and improving the use value of an infrared network camera.
Description
Technical field
The utility model relates to infrared imaging field, specifically infrared network video camera.
Background technology
Infrared ray is a kind of electromagnetic wave, and its position in electromagnetic wave continuous frequency spectrum is the region between radio wave and visible ray.Infrared radiation is a kind of electromagenetic wave radiation the most widely that nature exists, it is molecule and the random motion of atom that all can produce self based on any object under conventional environment, do not stop eradiation and go out thermal infrared energy, the motion of molecule and atom is more violent, the energy of radiation is larger, otherwise the energy of radiation is less.The object of temperature more than absolute zero, all can give off infrared ray because of the molecular motion of self.
Thermal infrared imager is that the infrared energy distribution pattern that utilizes Infrared Detectors and optical imagery object lens to accept measured target is reflected on the light-sensitive element of Infrared Detectors, thereby acquisition Infrared Thermogram, this thermography is corresponding with the heat distribution field of body surface.Generally thermal infrared imager is exactly that the invisible infrared energy that object is sent changes visible heat picture into.The different colours above of heat picture represents the different temperatures of testee.
At present, due to infrared video camera have the misty rain of overcoming ability strong, to temperature comparatively sensitivity and the feature such as smog penetration power is strong, therefore in forest fire protection field, obtained in recent years greatly application.But general infrared video camera can only return to vision signal at present, can not make alarm to some dangerous situations in real time.
Utility model content
The utility model provides infrared network video camera, has solved infrared video camera in the past and has not possessed network capacity, causes rear to operate it, the circumscribed problem that causes infrared video camera to use.
The utility model is that technical solution problem is achieved through the following technical solutions: infrared network video camera, comprise infrared optical lens, detector and front-end processing circuit, infrared optical lens is connected with detector, detector is connected with front-end processing circuit, it is characterized in that: also comprise subsequent conditioning circuit, the input of described subsequent conditioning circuit is connected with the output of front-end processing circuit, and the output of described subsequent conditioning circuit is connected with Ethernet interface.Infrared optical lens is used for seeing through specific infrared wavelength light wave, and it is focused to detector focal plane; Detector is the thermal effect of utilizing radiation, by thermoelectric (al) inversion technology, the thermal radiation of inciding detector focal plane is converted to certain width section analog voltage and exports; Front-end processing circuit for by this analog voltage amplify, analog-to-digital conversion; Subsequent conditioning circuit mainly carries out Digital Image Processing (processing comprising noise reduction filtering, little Target Recognition Algorithms), data visualization conversion etc., finally by Ethernet interface, realize transfer of data, picture signal can be sent it back to Surveillance center, Surveillance center also can pass through this Ethernet interface Long-distance Control The Cloud Terrace, camera lens etc.
