Preferably, the method for transferring power information integrated with the ACDC power module includes the following steps:
step S1: at least one piece of information to be transmitted, which is to be transmitted by the ACDC power module, is automatically generated or externally input;

step S3.2: based on the current modulation mode selected in step S2.4, the information to be transmitted is modulated in step S3.1 to enable the AC terminal to generate a relevant specific current waveform, so as to implement the information transmission while implementing the power output, thereby modulating and outputting the non-demodulated irregular waveform into a regular waveform capable of carrying effective information.
According to the embodiments, the difference analysis between the power information transmission method integrated with the ACDC power module disclosed in the present application and the existing ACDC power module capable of only realizing power output is as follows.
Specifically, in the conventional AC/DC module, a current fingerprint concept is not added, so that after the ACDC module is connected to a load, an output waveform is irregular, and power information cannot be transmitted. In contrast, the power information transmission method integrated with the ACDC power module disclosed in the patent application of the present invention realizes transmission or communication of power information based on current modulation, so that the ACDC power module has a function of power information transmission. In other words, based on the existing power output, information transmission can be further realized through current modulation, and external information expression can be realized.
According to the above embodiments, the working principle of the power information transfer method integrated with the ACDC power module disclosed in the present patent application is described as follows.
Specifically, the power information transmission method integrated in the ACDC power module is a method for performing power information transmission and communication by using (an existing ACDC power module), so that the existing ACDC power module has a function of information transmission.
Furthermore, the power information transmission method integrated in the ACDC power module can modulate the information to be output by adopting a current fingerprint technology. If the current fingerprint technology is adopted in the ACDC module (for example, the current fingerprint technology is applied to a chip for controlling on/off in the ACDC module), information encoded by the current fingerprint technology is directly coupled to the power output of the ACDC module during the power-on operation of the user.
In other words, it should be emphasized that, the power information transmission method integrated with the ACDC power module disclosed in the present application is not to modify an existing ACDC module (for example, a certain chip in the ACDC module), but to expand the capability of transmitting such power information based on existing various types of ACDC power schemes. Specifically, how can existing types of ACDC power schemes provide this information conveyance? The method is mainly based on a current fingerprint technology, and power information is transmitted or communicated by modulating information to be output onto an output waveform of output current.
That is, the ACDC power module is configured to use an existing ACDC power module (and a specific circuit structure thereof) to realize transmission, output, and expression (sub-function, new function) of (power) information based on realization of an existing power output (a main function, an existing function), and further use the existing ACDC power module (and the specific circuit structure thereof), as follows.
For example, notebook computers are typically equipped with a power adapter. The ACDC power supply module is arranged in the power adapter, and obviously, the ACDC power supply module of the power adapter has inherent characteristics, inherent capability and inherent use of power output, but when the power adapter provides output current for a notebook computer, the output waveform of the output current is irregular, so that the notebook computer can obtain electric energy with proper power level through the power adapter, but can not further obtain effective information by directly demodulating the output waveform of the output current.
It should be noted that, after the ACDC power module of the power adapter of the notebook computer applies the current fingerprint technology, the hardware structure of the ACDC power module is not changed, and the power adapter can still provide the output current to the notebook computer, so that the notebook computer can obtain the electric energy of the appropriate power level through the power adapter. Meanwhile, when the power adapter provides the output current as usual, the ACDC power module applies the current fingerprint technology, so that the current waveform of the output current is not irregular any more, and effective information can be further acquired by demodulating the output waveform of the output current.
It should be noted that the current fingerprint technology may be embodied as a current modulation method (including but not limited to a current modulation method, and the current modulation method itself has a plurality of embodiments), and the final purpose is to modulate information onto the output current, and implement information modulation and information transmission through controllable change of the output waveform of the output current.
It should be noted that the technical features such as the ac power grid related to the present patent application should be regarded as the prior art, and the specific structure, the operation principle, the control mode and the spatial arrangement mode of the technical features may be selected conventionally in the field, and should not be regarded as the invention point of the present patent, and the present patent is not further specifically described in detail.
It will be apparent to those skilled in the art that modifications and equivalents may be made in the embodiments and/or portions thereof without departing from the spirit and scope of the present invention.
