Description
Technical field
The present invention relates to the control technology field of audio amplifier, say so more specifically a kind of sound box non-contact inductive control system and control method thereof.
Background technology
Realize that by the infrared induction technology non-contact inductive control is a kind of control technology emerging in the electrical equipment, also represented a trend of following electrical equipment control.The volume control of carrying out audio amplifier by this technology also is a kind of technology of commonly seeing, as the patent No. is 02248331.4, name is called " the non-contact inductive volume is reconciled device " and application number is 200910105086.3, name is called " system that utilizes infrared induction control TV channel and volume ", in these disclosed background technologies detailed description how to adopt the infrared induction technology to realize control to the audio amplifier volume.
Yet this technology that has developed nearly 10 years but almost be can not see the application of its reality on market, and a lot of designs only are to be present in concept product, can perfect marketization.Though this is that but there is defective in its control technology because traditional infrared induction technology is ripe, is specially and coordinates a plurality of inductors and control corresponding with function.
As No. 02248331.4 patent, only there are two volume inductors arranged side by side, just a control volume increases, and a control volume reduces.Two inductors are parallel on the CPU, and emission simultaneously and reception infrared signal be feasible scheme in theory, but in actual applications, two infrared signals tend to the phase mutual interference.Though adopt the mode of spatial separation can reduce the possibility of interference, because audio amplifier is the very limited electrical equipment in a kind of volume, space, that also will consider to use is simple and easy, has increased the cost of industrial design greatly, and has used very inconvenient.And on common audio amplifier the volume controlled function of regulating just not, also have many other functions need carry out Artificial Control, as playing, stopping and a last song, next song etc.If have only volume contactlessly to control, and other functions also need touch controls, the contactless control very chicken ribs that then seems.When a plurality of inductors are parallel to when working simultaneously on the CPU, be to disturb very seriously on the one hand, also be easy to generate misoperation, and be can't coordinate by industrial design fully on audio amplifier; Be that the transducer of working simultaneously brings very big pressure for the data bandwidth of CPU on the other hand, the CPU that generally is built in the audio amplifier is the comparatively simple one-chip computer module of function, data bandwidth and disposal ability are all very limited, if handle a plurality of induction controls simultaneously, certainly will cause control lag and multiple misoperation.Though different inductors is adopted different signal encodings and adopts high-speed CPU to address the above problem, this will cause the cost straight line of audio amplifier to rise, and be unfavorable for popularizing and use.
And No. 200910105086.3 patent applications are owing to be to be applied on the panel TV, has bigger Signal Spacing space, can partly reduce the interference of four fired infrared receivers, even so, fired infrared receiver still must be arranged on four angle points of TV, disturbs so that further reduce.On the other hand four fired infrared receivers remain with single-chip microcomputer on four interfaces of P0.0-P0.3 be connected synchronously, the data-handling capacity for single-chip microcomputer has very high requirement like this.And from its specification as can be seen, when a plurality of fired infrared receivers have the signal feedback, be to be regarded as invalid data, this is difficult to be avoided in regular job, has caused the inconvenience of electrical equipment operation.
The critical defect that is exactly above-mentioned two another existence of technology in addition be exactly inductor be the work that continues, on the one hand bring high power consumption, the life-span of infrared transmitter shortens greatly on the other hand.And for audio amplifier this 1 year at least, the life requirements in 6 or seven years at most adopts existing conventional art to realize that non-contact inductive control obviously can't satisfy.A kind of price height, to use extremely short product of inconvenience and life-span obviously be the approval that can't obtain the consumer, this just why the infrared induction technology realize that non-contact inductive control has developed the reason that the more than ten years all can't widely apply.
Summary of the invention
Technical problem to be solved of the present invention is the defective that overcomes prior art, give existing infrared induction technology provide a kind of noiseless, the life-span long, sound box non-contact inductive control system and the control method thereof low to the data bandwidth requirement.
This patent can be applied in the existing electrical equipment by the infrared induction technology that changes control technology and make the more than ten years sluggish, and particularly little at this volume of audio amplifier, on the diversified product of control types, specifically technology is as follows:
Sound box non-contact inductive control system of the present invention, system configuration comprises: a plurality of infrared modules with infrared transmitter and receiver; Be used for programming infrared signal generator that infrared signal is encoded; Be used to control the infrared scan controller of infrared module circulation emission through the infrared signal of coding, the infrared scan controller comprises cycle controller and locking device; The master controller that is used to proofread infrared signal, control infrared scan controller and carries out feature operation; Be used to realize different control circuits to the multiple function control of audio amplifier; Concrete circuit structure is, the signal output part of above-mentioned programming infrared signal generator connects the infrared scan controller, the infrared scan controller is provided with a plurality of signal output parts and connects a plurality of infrared modules, its control end connects master controller, the infrared remote receiver of a plurality of infrared modules connects master controller, and master controller connects different control circuits and realizes function of loudspeaker box control.

The present invention is described further below in conjunction with accompanying drawing.
A kind of sound box non-contact inductive control system as shown in Figure 1, comprise: five infrared modules 41,42,43,44 and 45 with infrared transmitter and receiver, wherein infrared module 43,44 is used to control increasing progressively of volume and successively decreases, infrared module 41,42 is used to control the last bent and next is bent of music, and infrared module 45 is used to control music/stop and continuing/suspend (start/standby).In conjunction with loudspeaker box structure figure shown in Figure 2, infrared module 45 is arranged at the front of audio amplifier, and infrared module 41,42 is arranged at the left and right sides of audio amplifier, and infrared module 43,44 is arranged at the both sides, top of audio amplifier.
Above-mentioned infrared module is used to control the emission rule of infrared module circulation emission through infrared scan controller 2 its infrared signals of control of the infrared signal of coding by one.The cycle controller 21 of infrared scan controller 2 will be launched between each infrared module by certain cycle period by the infrared signal of programming infrared signal generator 3 short codes coding.Infrared scan controller 2 is by master controller 1 control.
Control principle of the present invention is that the 22 pairs of infrared modules of receiving triggering of locking device by infrared scan controller 2 lock, and calculates the time of triggering of continuing by timer 11, realizes control to function according to the difference of duration.
Above-mentioned five infrared modules are realized the volume control and the Play Control of audio amplifier, and concrete control procedure such as Fig. 3 are to shown in Figure 5.The control that increases progressively and successively decrease of volume as described in Figure 3, when handle is placed on the infrared module 43 of the audio amplifier left and right sides or 44 outsides, begin to enter timing control, continued duration that triggers and the increasing or decreasing speed that configures according to infrared module, control volume step increases progressively or passs, as whenever continuing to trigger the time interval through a Pang among Fig. 3, the volume that increases progressively doubles, and the volume of successively decreasing reduces 1/4.
As shown in Figure 4, a last song and next bent control method of music are the infrared module 41 or 42 outsides that handle is placed on limit, the audio amplifier upside left and right sides, master controller 1 enters timing control, long Pang when hot outer module is continued the duration that triggers greater than the switching that configures, the control music is song or next bent jump upwards.Promptly stop after once jumping song, to continuing to trigger no longer response, guaranteeing can misoperation.By continuous triggering, as shown in the figure, music will continue upwards bent or next bent jump, use very convenient.
As shown in Figure 5, in playing process, need to suspend in the broadcast, hand is placed on infrared module 45 outsides, audio amplifier front, between the Chang Pang 1～Pang 2 of Shi, stop to trigger, can make audio amplifier suspend and play; When halted state need continue to play, once more hand being placed on 45 Wai 1 times of Ce Pang of infrared module can continue to play.If need enter holding state at broadcast state, then hand is placed on infrared module 45 outsides, audio amplifier front, can make that through out-of-date long Pang 2 audio amplifier enters standby; Once more hand being placed on 45 Wai 2 times of Ce Pang of infrared module when need to open playing can open audio amplifier.The Chang Pang 2 of above-mentioned start/standby Shi makes and adopts an infrared module 45 can realize the control of four kinds of functions greater than the Chang Pang 1 of time-out/continuation Shi.
In the process that audio amplifier moves, misoperation for fear of hand, generally want the lock part function not to be triggered, be that lock part infrared induction module is not worked, the function of having only part to be difficult for being triggered in moving process is open-minded, as have only infrared module 43,44 work, and other infrared modules are not all worked.
The concrete control procedure of the present invention as shown in Figure 6.After energized, audio amplifier carries out system initialization, and 3 pairs of infrared signals of the infrared signal of programming then generator are encoded, and produces the infrared sources of a specific short code establishment.These are different with the employed long code infrared signal of common electrical equipment through infrared signal of specific coding, and influence that can outside infrared equipment also can not be disturbed the use of other household electrical appliance.
To circulate in certain sequence by infrared scan controller 2 through the infrared signal of coding and be forwarded on five infrared transmitters 41,42,43,44 and 45 emission, as pressing 41 to 45 order.Described infrared scan controller 2 inside have a high speed cycle controller 21 and be used for transmitting infrared signal between infrared transmitters, adopt at a high speed and transmit, and in use the people can not aware its trickle time difference, feels to be exactly that synchronized transmission is the same.And only open an infrared module in fact at every turn, and avoid the interference between each infrared module, and significantly reduced the signal processing amount, the infrared remote receiver of five infrared modules is by a bus 10 input master controllers 1 as shown in Figure 1.
In above-mentioned transmission infrared signal, carry out two monitoring, first is the monitoring to the function locking interruptive command, promptly whether the lock part infrared module is not activated.The interruption if receive orders is then adjusted 21 of cycle controllers and send infrared signal on specific several or infrared module, if do not receive, then continues circulation transmission infrared signal between all infrared modules.
Another monitoring is the infrared signal whether the infrared remote receiver monitoring has reflection, and when handle was put into the outside of infrared module, hand had become the usable reflection thing, and the infrared signal that emits is reflexed to infrared remote receiver.This monitors distance is controlled, generally can monitor apart from being controlled within several centimetres to tens centimetres the triggering degree of signal feedback amount by establishment and adjusting infrared remote receiver to infrared signal.When carrying out audio amplifier control, hand need not to contact audio amplifier, forms non-contact inductive control.Can understand from the emission mechanism of above-mentioned infrared signal, the reflector that at every turn has only one of them infrared module that is to say and has only a corresponding receiver can receive signal in work.Receive that when this specific infrared remote receiver carrying out amplification filtering after the infrared signal of reflection handles, and the efficient coding data are delivered to master controller 1 carry out the data correction process.After proofreading successfully, master controller 1 sends instructions to infrared scan controller 2, and the current infrared transmitter of control locking device 22 lockings sends infrared signal continuously.
After the locking, master controller 1 enters time-delay control, just starts timer 11 after the check-back signal success through continuing after a while and enters timing control.The pairing controlled function of master controller 1 this infrared module of identification sends instructions to pairing control circuit and realizes function of loudspeaker box control at the same time, and concrete control procedure is as described in Fig. 3 to 5.
When handle is removed, infrared remote receiver is no longer received the infrared signal of reflection, and then infrared scan controller 2 is from new startup loop control reflector emission infrared signal.
