Abstract
The utility model discloses an LCD advertising machine with a function of human body sensing. The LCD advertising machine comprises an LCD and a power circuit, and also comprises a Fresnel lens, an infrared pyroelectric detector, an infrared sensing signal processor, and a video play integrated circuit. If a user presets the human body sensing to be silent and presets a corresponding human body sensing time, when a playing video file plays to the preset human body sensing time and the infrared pyroelectric detector does not detect a human body, the playing video enters an automatic silent state. In a similar way, if the user presets the human body sensing to sleep, when the infrared pyroelectric detector does not detect a human body, the LCD turns off automatically and enters a sleep state. If the infrared pyroelectric detector detects human body infrared rays, the LCD is waken up and the LCD advertising machine continues to play the video file. The LCD advertising machine is advantaged by having the function of human body sensing, playing the advertisements when someone passes by, and having a rest when no one exists, saving electric energy, etc.
Description
Technical field
The utility model relates to electric equipment, especially relates to a kind of liquid crystal advertiser with human body induction function.
Background technology
Because the fast development of China's economy, people are more and more higher to the pursuit of high-quality life, and advertisement has become an indispensable part in people's life.
Advertise now and mainly contain following several mode: 1, Still Media, such as newspaper, magazine, promotional pamphlet etc.; 2, dynamic media is such as indoor tv, outdoor TV, broadcasting, scrolling billboard etc.Still Media lacks innervation owing to tone, pattern are all comparatively dull, and content is single again, is difficult to satisfy people's visual demand; Although and dynamic media tone, pattern are all very abundant, picture is smooth, abundant in content, can fully satisfy people's visual demand, but also exist and play part in advertisement possessor no one can long-time continuous play, do not have the audient to witness advertisement, the switch that do not have shortcomings, particularly some outdoor televisions such as any advertising results also needs the artificial manipulation of switches time, thereby reach the intermittently purpose of broadcast advertisement, very trouble is made troubles to the staff.In addition, these TVs are play for a long time, both can consume a large amount of electric energy, can affect again the life-span of TV.
Summary of the invention
The purpose of this utility model be to provide a kind of with human body induction function, have the people through out-of-date broadcast advertisement nobody the time have a rest, save electric energy, prolong the TV life-span, liquid crystal advertiser simple in structure, with low cost.
The purpose of this utility model is achieved in that
A kind of liquid crystal advertiser with human body induction function, comprise LCDs and power circuit, also comprise Fresnel Lenses, infrared electric heating is released probe, infrared sensor signal processor and video playback integrated circuit, the Fresnel Lenses that is used for the collection infrared light supply is positioned over the front that infrared electric heating is released probe, infrared electric heating is released the transducing signal output termination of probe as the transducing signal input end of the infrared sensor signal processor of human body induction module, the infrared signal input end of the infrared signal output termination video playback integrated circuit of infrared sensor signal processor, the VT of video playback integrated circuit connects the video signal input terminal of LCDs.
Power circuit is comprised of regulator, low pressure difference linear voltage regulator and wide input step-down controller, regulator general+12V voltage is output+5V voltage after the DC-to-dc conversion, supply with low pressure difference linear voltage regulator, low pressure difference linear voltage regulator general+5V voltage transitions one-tenth+3.3V voltage supplying video is play integrated circuit, wide input step-down controller general+12V is output+1.2V voltage after the DC-to-dc conversion, and supplying video is play integrated circuit.
The utility model is released probe, infrared sensor signal processor, video playback integrated circuit and power circuit by LCDs, Fresnel Lenses, infrared electric heating and is formed, it is that system in infrared sensor signal processor arranges two kinds of patterns that the inside sets in advance human body sensing: silent mode or sleep pattern, and after the switching on and shutting down time of human body sensing, logging off arranges the interface again.When needs are play video file with advertisement, plug in, normally start and play the video file that contains advertisement, it is the quiet and corresponding human body sensing time if set in advance human body sensing, be played to the time of human body sensing setting when the video file of playing after, when infrared electric heating was released probe and do not detected human body sensing, the video of broadcast just was in the automatic mute state; In like manner, be sleep if set in advance human body sensing, when infrared electric heating was released probe and do not detected human body sensing, LCDs will be turned off automatically, and the utility model stops playing video file, is in dormant state; If wake LCDs up, detect human body infraredly as long as infrared electric heating is released probe, the video playback integrated circuit just is waken up, and the utility model will continue playing video file.Therefore, the utlity model has with human body induction function, have the people through out-of-date broadcast advertisement nobody the time have a rest, can save electric energy, prolong the TV life-span, advantage simple in structure, with low cost.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of liquid crystal advertiser with human body induction function, by LCDs 5, Fresnel Lenses 1, infrared electric heating is released probe 2(RE200B), infrared sensor signal processor 3(BISS0001), video playback integrated circuit (AML7216) and power circuit 6 form, the Fresnel Lenses 1 that is used for the collection infrared light supply is positioned over the front that infrared electric heating is released probe 2, infrared electric heating is released the transducing signal output termination of probe 2 as the transducing signal input end of the infrared sensor signal processor 3 of human body induction module, the infrared signal input end of the infrared signal output termination video playback integrated circuit 4 of infrared sensor signal processor 3, the VT of video playback integrated circuit 4 connects the video signal input terminal of LCDs 5.
Fresnel Lenses 1 utilizes the special optical principle of lens, and the place ahead of releasing probe 2 at infrared electric heating produces " blind area " and " highly sensitive district " that alternately changes, to improve its detection receiving sensitivity.Out-of-date when there being the people to walk from the front of Fresnel Lenses 1, the infrared ray that human body sends just constantly alternately enters " highly sensitive district " from " blind area ", so just make infrared electric heating release probe 2 infrared signals that receive with dynamic impulse form input, thereby strengthen the energy discharge amplitude that infrared electric heating is released probe 2.The infrared signal of input enter infrared sensor signal processor 3 the insides carry out operation amplifier, voltage ratio, delay time regularly, after the blocking time Timing Processing, the pulse signal of output height.The pulse signal that video playback integrated circuit 4 is responsible for reception infrared sensor signal processor 3 goes to process, thereby realizes the function of human body sensing.
More than be that the liquid crystal advertiser of the utility model band human body induction function is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
