Description
Technical field
The present invention relates to a kind of Portable thermal that carries out image wireless transmission as photorecorder, in particular, relate in particular to a kind of long transmission distance and can to the scene observe and the Portable thermal of the carried out image wireless transmission of recording as photorecorder.
Background technology
Society enters the information age, and along with socioeconomic fast development, social public security also is subject to people and more and more pays close attention to, and the safety monitoring industry development is swift and violent, and the development of Intelligent security monitoring technology has obtained the achievement that attracts people's attention.Thermal imaging has obtained the generally approval in domestic security protection market, and dual-use market is more and more to the demand of thermal imaging monitoring.The security protection that exists in the market has two kinds of forms with thermal infrared imager: fixed, portable.Fixed thermal imager need to be fixed on equipment certain position, and fixing regional extent is monitored, and adopts coaxial cable to carry out the analog video signal transmission, and the analog video signal decay is serious, and transmission range is near, and very flexible; Portable thermal imager can be used as monomer and uses, and according to staff's needs, monitors to different places, what video adopted is that the scene is watched in real time, perhaps carries out video record, can't conveniently realize carrying out with the commanding in the rear center real-time Transmission of image, response lag, networked capabilities is poor.
Summary of the invention
The present invention is in order to overcome the shortcoming of above-mentioned technical problem, provide a kind of long transmission distance and can to the scene observe and the Portable thermal of the carried out image wireless transmission of recording as photorecorder.
The Portable thermal of image wireless transmission that carries out of the present invention is as photorecorder, comprise infrared lens, thermal imaging detector, play the CPU module of computing and control action and be used for the eyepiece that the visual field is shot with video-corder in observation, thermal imaging detector is used for light signal is converted into analog video signal; The data processing circuit of the output of thermal imaging detector through analog signal being converted into digital signal is connected with the CPU module; Its special feature is: the output of described thermal imaging detector is connected with wireless transport module, and wireless transport module is realized coding, modulation and the wireless transmission that analog video signal carries out.
Infrared lens is realized the infrared imaging of extraneous scenery, and thermal imaging detector is used for light signal is converted into the signal of telecommunication, and the formation analog video signal is exported.CPU realizes collection, computing and control action; The person of shooting with video-corder is by the captured regional extent of eyepiece Observable.Data processing circuit is used for the analog signal of thermal imaging detector output is converted into digital signal, shows and the utilization of CPU module for eyepiece.Wireless transport module is encoded the analog video signal of thermal imaging detector output, in order to be converted into digital signal; Send with the form of wireless signal again after the modulation, realized remote, the wireless transmission of Infrared Video Signal.
The Portable thermal that carries out the image wireless transmission of the present invention is as photorecorder, and described CPU module is connected with the video record module.When needs are taken scene, can by the video record module with the infrared video information recording/at scene, preserve.
The Portable thermal that carries out the image wireless transmission of the present invention comprises the centre receiver of the wireless video digital signal that reception and demodulation wireless transport module transmit as photorecorder, and centre receiver is connected with the center monitor for display frame.Centre receiver be used for to receive the vision signal that the wireless transport module on the thermal imagery photorecorder sends, and after the demodulation code, send and puts center monitor and show, in order to realize the supervision effect.
The invention has the beneficial effects as follows: (1) Portable thermal that carries out the image wireless transmission of the present invention gathers image as photorecorder by infrared lens and thermal imaging detector, output infrared simulation vision signal.Vision signal is divided into two-way, leads up to data processing circuit, carries out Video coding, after the processing by CPU, both can carry out the real-time recording of video, can drive the eyepiece display video again, makes things convenient for field personnel's observation; Another road vision signal outputs to wireless transport module, encodes and modulates, and is transferred to command centre with wireless, the video of command centre by can real-time monitored after the demodulation code feeding back to the place ahead wireless transmission.So that Portable thermal of the present invention has following characteristics as photorecorder: the wireless transmission of (1) image adopts wireless communication module, and communication distance is far away, and traffic rate is high, and conversion speed is fast; (2) can stablize, the reliable real-time recording of video image; (3) can carry out the real-time monitored of video image by eyepiece, convenient and practical.
Whole thermal imagery photorecorder is reliable, stable, easy to use, antijamming capability strong, long transmission distance, and the urban district transmission range better can reach 10km under the condition greatly about 4km.Can be widely used in the remote-wireless supervisory control system in the fields such as public security, People's Armed Police, fire-fighting, traffic, finance, oil field, factories and miness.
