Description
Technical field
The present invention is to provide the method for transfer of data in a kind of inductive power-supply supply device, see through supply module utilization power supply coil and transmit electric energy and the transmission of data signal, see through the electromagnetic wave signal and be linked to and be subjected to electric module to be subjected to electric coil to receive electric energy and the transmission of data signal, reach the purpose of synchronous charging, the transmission of data.
Background technology
living environment enters digital Age, various digital products more are full of arround life, digital camera for example, mobile phone, music player (MP3, the various portable electronic devices such as MP4), and various portable electronic devices, product is all towards gently, thin, short, little design concept, but as will to reach what can portably use at any time that at first purpose must solve be namely the problem of electricity consumption, the most general general mode is installed rechargeable battery exactly in portable electronic devices, when power drain, can again charge, but everyone has a plurality of portable electronic devices now, the charger that each own specific phase of each portable electronic devices is held, whenever buying new portable electronic devices, just need the extra corresponding charger of buying, just can increase burden economically, and need take again large quantity space takes in, more all together take in because of the charger of plural electronic installation, when the needs particular charger, can producing again expends time in seeks the disappearance of comparison.
But charger is when using, must be plugged into supply socket with connecting interface (plug), connector with the other end is plugged into portable electronic devices again, its portable electronic devices is charged, after to be charged completing, the electrical equipment on the sub-device that just will charge removes, and so need to can electrically peg graft just now, charge on the ground that supply socket is arranged because of charger, the place that causes charging is restricted, and outdoorly namely can't charge if be in.
as another, electronic installation is except charging, also must carry out the setting of correlation function or the editor of data, transmit etc., directly set except seeing through electronic installation, outside input, some electronic installation (as: music player (MP3, MP4 etc.), digital camera, electronic watch, the portable game machine, the wireless game handgrip, controller etc.) also can't directly set, must see through other electronic product (computer, personal digital assistant etc.) just can carry out function setting, the transmission of data, and general electronic installation is when charging, and can't synchronously carry out the transmission of data, must separately carry out.
And openly number " the inductive power-supply supply system of tool battery types detecting function " disclosure of the invention case of No. 201004086 as TaiWan, China, to file an application on February 20th, 2009, application case number No. 98105373, and be disclosed in the open communique on January 16th, 2010, be a kind of method that discloses load type resistance modulation signal, for the inductive power-supply supply system, the secondary coil signal fed back to the method for elementary signal, but when practice, be to have following disappearance:
(1) the resistance changing device can be when the modulation signal consumed power, the modulating signal dynamic range wants size to be determined by the load resistance value, be that in the inductive power-supply supply system, primary coil will be analyzed the signal size, can be along with secondary coil reduces apart from increase, so need larger modulation dynamic after distance strengthens, the way resolution data is just arranged, namely reduce resistance value so that amplify load effect in modulated process, but this kind mode is the restriction of the limit to some extent, because modulation load resistance near short-circuit condition, can't reduce again.
(2) in the ohmic load modulated process, near short-circuiting effect, cause the large electric current of moment to pass stable-pressure device on rectifier and its loop just as receiving end positive source and ground connection, use the temperature rising can cause the damage of relevant spare part.
(3) and ohmic load due to the restriction on electrically, need to be located at the rear of rectifier, have again filter capacitor to be connected across its two end, the effect of voltage stabilizing causes signal modulation reaction speed slow, under analysable state, need higher carrier frequency just can operate.
(4) transmission of its signal for feeding back to elementary power supply coil signal by the secondary electric coil signal that is subjected to, as the method for one-way transmission data, and can't be sent to the secondary method that is subjected to the electric coil signal to transmit data by elementary power supply coil signal.
Therefore, how to solve and commonly use electronic installation in problem and the disappearance of the operations such as charging, setting and transfer of data inconvenience in enforcement, running, and charging must separate the puzzlement of carrying out, use different electronic product or equipment from transfer of data, is the relevant manufacturer that is engaged in the industry and desires most ardently the direction place that research improves.
