The infrared-sensing controlled media player can achieve a human-computer interaction conveniently by consuming less or no energy. The infrared-sensing controlled media player has high sensitivity and is widely applied to fixed electronic devices (such as large-scale computers, desktop computers and the like) and portable electronic equipment (such as PDAs, cellphones, MP3s and the like).
Description
Technical field
The present invention relates to a kind of multimedia playing apparatus, particularly a kind of infrared sensing controlled media playing device.
Background technology
At present, electronic equipment commonly used is controlled after all needing manual type to start as apparatus for media playing etc., if should need electronic equipment in some, particularly apparatus for media playing can start or adjust the occasion of duty automatically at user situation, then comparatively is not suitable for.For this reason, people develop several different methods existing electronic equipment is transformed, to realize the interaction of user and electronic equipment easily, wherein common mode is to load the infrared inductor that is made of infrared emission and receiving element on electronic equipment, as Chinese patent publication number CN2852271, a kind of money box that the utility model patent in open day on Dec 27th, 2006 proposes with voice and image demonstration, it comprises casing, place the coin slot of casing upper end and the multimedia advertising display screen on the casing, coin slot is provided with infrared inductor, infrared inductor is electrically connected with the master controller of multimedia advertising display screen, when the people contributes money the reception of input coin slot blocking-up infrared induction, master controller starts the multimedia advertising display screen synchronously, Chinese patent publication number CN200997108 and for example, a kind of infrared interactive image system that the utility model patent in open day on Dec 26th, 2007 proposes, it comprises projector, infrared camera, main frame, the infraluminescence pipe, multimedia loudspeaker box, catch people's in the drop shadow spread (group) motion and be converted into control information by infrared camera, change the image of projections output and the sound of audio amplifier output with these control informations, realize people (group) and audio-visual between interaction.But these infrared sensing devices usually need be by the power supply of peripheral hardware power supply with after outwards sending infrared ray, can operate as normal, therefore be only applicable to have the place of stable power supply, or if be applied to such as portable electronic equipments such as mobile phone, MP3, PDA, then need consume the electric weight of a part of battery, thereby shorten the stand-by time of these electronic equipments.
Summary of the invention
The objective of the invention is to propose a kind of can be less or need not consumes energy, can realize human-computer interaction easily, and highly sensitive infrared sensing controlled media playing device, to overcome deficiency of the prior art.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of infrared sensing controlled media playing device, comprise a data processing unit, a display unit, a Nonvolatile storage unit, it is characterized in that this media playing apparatus comprises that also one can export the infrared sensor of a simulating signal with outside infrared signal Strength Changes, this infrared sensor is connected with data processing unit.
Particularly, described infrared sensor comprises probe unit and signal processing unit, probe unit receives the infrared ray that user's body sends, and generation electric signal, electric signal is converted to a simulating signal through signal processing unit, when this simulating signal arrives certain amplitude, then triggers a switching signal, and send to data processing unit, start media playing apparatus.
Described probe unit comprises that a pair of surveys a first pyroelectric infrared sensor and an optical filter, and after Filtering Processing, the infrared ray that wherein has certain wavelength focuses in the detection unit of probe unit the infrared ray that user's body sends through the optical filter place.
Described infrared sensor also comprises an optical system, and the infrared ray that user's body sends is collected through this optical system, and focuses to probe unit.
Described optical system comprises Fresnel Lenses.
Described signal processing unit comprises a signal amplification unit, a comparer and a displacement monitoring device at least, the electric signal that probe unit produces is successively after signal amplification unit and comparer processing, transfer to the displacement monitoring device, and be converted to a simulating signal through the displacement monitoring device, when this simulating signal arrives certain amplitude, then trigger a switching signal, and send to data processing unit.
This media playing apparatus also comprises a hand-held sandwich type element, and described data processing unit, Nonvolatile storage unit and infrared ray sensor all are arranged in this housing, and the display screen of described display unit is arranged on the housing.
Also being provided with one in this media playing apparatus can be for the control panel of user input instruction, and this control panel is connected with data processing unit.
This infrared sensing controlled media playing device adopts the mode that the infrared sensor of a passive type is set in existing electronic equipment, make the electronic equipment can be according to state of user, action as the user, the distances of user and electronic equipment etc. are operation or adjustment duty automatically, thereby well realize human-computer interaction, especially it is to be noted, above-mentioned infrared sensor only can move by the infrared ray with specific wavelength that receives outside infrared emitter emission, can be less or need not to expend the energy, the additional infrared sensor that the infrared parts are set, effectively energy savings compared to prior art.
Infrared sensor in this infrared sensing controlled media playing device preferably adopts the infrared sensor that mainly is made of pyroelectric infrared sensor, more preferably adopt the first pyroelectric infrared sensor of two detections with filter function, the infrared wave segment signal sensitivity that this kind infrared sensor only sends the human body in the motion, animal etc., and can not disturbed by the infrared emitter of stationkeeping in the environment, therefore, sensitivity is higher.Comparatively the mode of You Huaing is, also comprises one in this infrared sensor by lens, and the optical system that constitutes as Fresnel Lenses etc. like this can more effective reception human body or the infrared signal that sends of animal.
Compared with prior art, beneficial effect of the present invention is: this infrared sensing controlled media playing device can be less or be need not consumes energy, can realize human-computer interaction easily, and highly sensitive, can be widely used in such as stationary electronic devices such as mainframe computer, desktop computers with such as in the portable electric appts such as PDA, mobile phone, MP3.
