Abstract
The utility model relates to a digital player, in particular to a digital player with an infrared sensing device, which includes a digital player body. The digital player body is provided with an infrared sensing device which can realize non-contact control during detecting the infrared emitting source, the circuitry of the infrared sensing device consists of an infrared emitting circuit and an infrared receiving circuit. The digital player has the advantages that the circuitry of the infrared sensing device is very simple and can be easily debugged, the sensitivity is very high, the detection range can meet common demands (20-30cm away from the front of the machine); when no infrared controller is available, the infrared sensing device can be used to conduct non-contact control on parts of functions of the digital player, and to provide fine man-machine conversation operation which facilitates the control operation; in particular after the infrared sensing device is applied on a digital picture frame, and that the infrared sensing device senses objects on the front is realized on the digital picture frame, the selection of various working states of the machine body of the digital picture frame can be controlled.
Description
Technical field
The utility model relates to a kind of digital code player, relates in particular to a kind of digital code player with infrared inductor.
Background technology
Infrared inductor is widely used in the modern life, as parking lot, monitoring, meeting room and factory building or the like.Can accurately detect the variable in distance of people or mobile object, to reach the purpose of monitoring.Though existing general infrared inductor can satisfy the needs of general daily life, but also have following some shortcomings part, for example investigative range is little, infrared emission power is limited, the life-span of transmitting tube is short, along with the growth service time sensitivity etc. that can become not too.
Be that existing digital code player generally all is the various operations of using by the key control digital code player in addition, some new product has also used the pattern of remote controller control, but all there are some inconveniences in button and remote control mode, key mode just needs the frequent pressing keys of user, can feel loaded down with trivial details when especially controlling DPF especially.And remote control mode just needs to use a remote controller, because the user need often carry, therefore loses easily or damages by pressure.
In the weak point aspect the control operation, the inventor has designed the utility model " digital code player with infrared inductor " based on above-mentioned digital code player.
Summary of the invention
The utility model at above-mentioned the deficiencies in the prior art technical problem to be solved is: provide a kind of control easy, the simple in structure digital code player with infrared inductor.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of digital code player with infrared inductor, comprise a digital code player body, described digital code player body is provided with the infrared induction device of realizing contactless control when surveying infrared emitter, and the circuit of this infrared induction device is made up of infrared transmitter and infrared radiation receiving circuit.Utilize the infrared induction device, do not having under the situation of IR remote controller, the partial function of logarithmic code player carries out contactless control, and good human-computer dialogue operation is provided.
Described digital code player body is a DPF, the infrared induction device is located on the DPF, after realizing infrared induction device induction objects in front on the DPF, with selecting of the various duties of control this machine of DPF, to realize human-computer dialogue operation abundant more except that remote control.
Described infrared emission circuit is made up of infra red treatment chip, infrared emission tube, crystal oscillator, amplifying triode, electric capacity and resistance, and described infrared radiation receiving circuit is made up of infrared receiver tube and electric capacity.
Described infra red treatment chip model is PT2221, and it also can have the chip of similar functions for other.
The digital code player beneficial effect that the utlity model has infrared inductor is:
The circuit of infrared induction device is very simple, debugging easily, induction sensitivity is very high, investigative range can satisfy general needs (in machine the place ahead 20-30CM distance), utilize the infrared induction device, do not having under the situation of IR remote controller, the partial function of logarithmic code player carries out contactless control, good human-computer dialogue operation is provided, be convenient to user's control operation, especially be applied on the DPF, after realizing infrared induction device induction objects in front on the DPF, with selecting of the various duties of control this machine of DPF, to realize human-computer dialogue operation abundant more except that remote control.

The specific embodiment
Referring to figs. 1 through Fig. 6, the utility model is to implement like this:
In Fig. 1, Fig. 2 and Fig. 3, a kind of digital code player with infrared inductor, comprise a digital code player body 10, digital code player body 10 is provided with the infrared induction device 20 of realizing contactless control when surveying infrared emitter, and the circuit of this infrared induction device 20 is made up of infrared transmitter 21 and infrared radiation receiving circuit 22.Utilize infrared induction device 20 not having under the situation of IR remote controller, the partial function of logarithmic code player carries out contactless control, and good human-computer dialogue operation is provided.
In the present embodiment, digital code player body 10 is a DPF, infrared induction device 20 is located on the DPF, after realizing infrared induction device 20 induction objects in front on the DPF, various duties with the control DPF are selected, to realize human-computer dialogue operation abundant more except that remote control.
Using method of the present utility model is: in Fig. 4, the function of establishing infrared induction device 20 earlier is for opening, infra red treatment chip 211 can be regulated infrared emission tube 212 automatically and produce infrared ray 30 then, after passing through amplifying triode 214, infrared ray power will increase, infrared emission tube 212 just can penetrate the infrared ray 30 of free rule then, in Fig. 5, because infrared ray 30 can be reflected, therefore when having bar to appear at infrared induction device 20 fronts, infrared receiver tube 221 all can be received the infrared ray 30 that is reflected, and in addition, the distance of object and infrared induction device 20 can be adjusted by system.In Fig. 6, when receiving the infrared ray 30 that is reflected, infrared receiver tube 221 meeting output signals 40 also pass to system, the circuit of meeting altered activation photograph when signal 40 process digital signal processors 11, and change picture in real time.
The above, it only is the digital code player preferred embodiment that the utlity model has infrared inductor, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology contents any trickle modification, equivalent variations and modification that top embodiment did.
