Description
Technical field
The present invention provides the method for two-phase decoding in a kind of high power inductive power-supply supply device, but espespecially synchronous driving power supply, data signals, and regulate power supply coil and the watt level that is subjected to electric coil, and pass through the operation of two-phase Data Analysis in the receiving end full load, correct resolution data code still, and make the system stability running.
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 purpose at first must solve namely be 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 and take in, more all together take in because of the charger of a plurality of electronic installations, when the needs particular charger, can producing again expends time in seeks the disappearance of comparison.
But charger in use, 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 the finishing, just the electronic installation on the charger is removed, 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.
Electronic installation is except charging as another, also must carry out the setting of correlation function or the editor of data, transmit etc., except directly setting by electronic installation, outside the 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 be by other electronic product (computer, personal digital assistant etc.) just can carry out function setting, data transfer, and general electronic installation is when charging, and can't carry out synchronously data transfer, must separately carry out; And the inductive power-supply supply device of releasing on the market at present (or claiming the wireless type charger) is to utilize two coils, one of them is as the feeder ear of emission electric power, another is used as the receiving end that receives electric power and operates, because the energy of wireless power has danger, can heat metal object, principle can cause the object that is placed on the feeder ear to cause easily the phenomenon of damage or fault because being heated as electromagnetic oven.
And in the inductive power-supply supply device, for safe operation, then necessary mutually identification between feeder ear and the receiving end, could begin to power, namely under the demand of function like this, need to set up the method that the control numeric data code transmits at feeder ear and receiving end, and the necessary quite stable of the transmitting function of numeric data code, just can make electric power transmit stable running, former times knows in the technology it is to change the load state that is subjected on the electric coil in the receiving end modulation, on the coil that feeds back to feeder ear, after utilizing the electric circuit inspection signal to change, take out numeric data code with the default analysis program that arranges again, right so practice is when stablizing when being added in the load of receiving end output power end, can adopt, if the load of receiving end output power end is the situation of change, namely can not use, because of the load of output power end for having influence on originally modulating signal on the receiving end, cause the transmission of numeric data code can't stablize running.
In addition, when the receiving end output power is in full load conditions, because the output impedance state changes, can make the reversing of feeder ear analytic signal, once namely can't resolution data after the reversing, transmit and interrupt and cause the control data, and the function of directly impact charging can't operate smoothly.
Therefore, how solving existing electronic installation is charging synchronously, can't stablize problem and the disappearance that transmits numeric data code during the operation of transfer of data, and charging and data transfer, what be subject to easily that load characteristic between feeder ear, the receiving end changes influences each other, so that the puzzlement that the data signals Transmission maybe can't transmit is the relevant manufacturer that is engaged in the industry and desires most ardently the direction place that research improves.
So, the inventor is because above-mentioned problem and disappearance, be to collect related data, via in many ways assessing and considering, and to engage in the many years of experience of the industry accumulation, via constantly studying and revise, but but begin to develop this kind supplied for electronic and be installed on when charging still stable transfer data signals, the patent of invention for the method for two-phase decoding in the high power inductive power-supply supply device of system stability running is born.

Data signals is signal that can't identification, then prepares to close output.
(205) power supply microprocessor 11 prepares to receive next bit data signals, and waits for that the transition of data signals modulation triggers.
(206) transition that signal parser circuitry 13 detects of passing through of power supply microprocessor 11 triggers, then stop timer and judge the state of present data signals, if in the modulation, namely carry out step (207), if in non-modulation, namely carry out step (208).
(207) data signals in 11 modulation of power supply microprocessor, checking whether timing length meets between the previous transition signal is length range in the modulation of (1) or (0), if meet, namely carry out step (209), if do not meet, namely carry out step (204).
(208) data signals in 11 modulation of power supply microprocessor, check whether timing length between the previous transition signal meets the non-modulation middle length range for (1) or (0), if meet, namely carry out step (209), if do not meet, namely carry out step (204).
(209) data signals of power supply microprocessor 11 detectings is namely inserted corresponding logical code in reception memorizer in length range.
(210) whether power supply microprocessor 11 checks to finish receiving the bit number of appointment, if finish receiving, namely carry out step (211), if do not finish receiving, namely carry out step (205).
(211) power supply microprocessor 11 confirms with the data signals that receives whether the numeric data code form is correct, if correct format, namely carry out step (212), if form is incorrect, namely carry out step (204).
(212) power supply microprocessor 11 confirms that numeric data codes are correct formats, and enters powering mode, carries out homework of supplying power by driving power supply units 16 for electric drive unit 12, and that utilizes 171 power supplies of power supply coil to be induced to be subjected to electric module 2 is subjected to electric coil 281.
Again, the power supply microprocessor 11 of supply module 1, sending extremely short signal detecting, can identify the data signals of the data signals that is subjected to electric module 2 transmission, and when power supply microprocessor 11 built-in two groups of comparators, it is non-in institute's range of receiving to receive noise or data length, power supply microprocessor 11 is about to the two-phase decoding program and resets, and after finishing data receiver, also the two-phase decoding program can be reset, allowing next time, trigger signals determines the decode phase configuration again.
