摘要:
The present invention provides a method of time-synchronized data transmission in induction type power supply system, comprising timers and programs installed in a supplying-end module and a receiving-end module to predict the time for generating the trigger signal at the receiving-end end and perform steps for detecting signals to avoid omission. Under the condition of high power transmission, power output on the supplying-end coil is pre-reduced prior to the time expected for receiving trigger data, making the main carrier wave amplitude decrease in a short time period. In every process of data transmission, timers are mutually calibrated and synchronized again to transmit power without detecting and receiving in the period when no data are expected to be transmitted, thus preventing interference of power load noise and enabling the induction type power supply system to transmit data code stably.

A low-loss data transmission method used in a high-power induction-type power supply system consisting of a supplying-end module and a receiving-end module is disclosed. The supplying-end microprocessor of the supplying-end module has built-in anti-noise signal analysis software that can remove noises from the data signal fed back by the receiving-end module, assuring high stability of the transmission of data signal and reducing energy dissipation of data transmission. Subject to a special circuit arrangement of the receiving-end coil of the receiving-end module, signal modulation is performed on a low voltage DC square wave, assuring a high level of stability of the supplying of power supply to the receiving-end module.

The present inventions relates a wireless charging coil structure in electronic devices, comprising a PS coil module capable of emitting electromagnetic wave energy and a PR coil module capable of receiving power energy by electromagnetic induction. Each of the PS and PR coil modules includes a bar-shaped magnetic conductor, on which an insulated wire is wound into a first coil that is extended along the magnetic conductor to a given length and wound reversely into a second coil, thus producing an induction coil comprising at least the first and second coils. The induction range with given space formed between the first and second coils is used for electromagnetic induction to transmit signals and power energy. Such structure can be applied not only in planar handheld electronic devices, but also in other wireless power transmission systems that require narrow induction surface for power transmission.

The present invention relates to an inductive charging method for vehicles, in which the PS device uses a first frequency converter PS module to detect the PR device. The PS microprocessor can compare ID codes of the PR device and check power receiving status data codes. When finding incorrect power supply, the PS microprocessor will mark it and make other first frequency converter PS modules to cut off power supply through the signal control circuit, and even adjust output power based on power status data codes from the PR device. As total voltage of the PR module is increased by series connection, it is not necessary to use components of high-voltage specifications and water cannot go into sockets, thus preventing electricity leakage. Besides, no wired connection is required and operations concerning identification, stored value or deductions can be carried out.
