The frequency of the POS machine is fixed, and the NFC antenna of the mobile phone works at different frequencies and has different coupling strengths with the POS machine. The current mode control chip sets a current threshold value, sufficient energy cannot be provided for the NFC chip to normally work when the current mode control chip is lower than the threshold value, the variable capacitor C0 is manually controlled to poll between 1-20 pf, the working frequency of the NFC mobile phone can be changed, when the current mode control chip monitors that the current is larger than the threshold value, the NFC chip of the mobile phone can normally work, at the moment, the antenna of the mobile phone is coupled with the POS machine in an entering mode, the mobile phone is normally and quickly used when the POS machine is clicked, and the size of the capacitance value of the variable capacitor C0 is kept unchanged.
The technical scheme still remains how to adapt to various terminals before the mobile phone leaves the factory. And after the mobile phone leaves the factory, the working frequency of the mobile phone can not be dynamically adjusted.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The working principle of the technical scheme is as follows: as shown in fig. 1, it is a schematic diagram of the working principle of the present technical solution. The operating frequency of the conventional receiving terminal (such as a POS machine) should be 13.56MHz, but due to device errors, aging and the like, the operating frequency of the receiving terminal is shifted, and the operating frequency of each receiving terminal is different. According to current practical experience, in order to adapt to the drift phenomenon of the operating frequency of the receiving terminal, the operating frequency range of the mobile phone antenna is set to be between 13MHz and 18 MHz. Several groups of adaptation circuits formed by inductors and capacitors are adjusted in advance on a mainboard of the mobile phone, an adaptation circuit is selected from a plurality of groups of adaptation circuits by controlling corresponding electronic switches through an APP, the working frequency of the adaptation circuit after being combined with a coil on the mobile phone changes, and the mobile phone is matched with the acceptance terminal by adjusting the working frequency of a mobile phone antenna.
Based on the above working principle, the present invention provides a mobile phone, as shown in fig. 2. The method comprises the following steps: a frequency adjustment unit 201, a coil unit 202, and an NFC chip 203; wherein,
the frequency adjusting unit 201 is configured to send a control command to the coil unit 202 according to the operating frequency of the receiving terminal;
the coil unit 202 is configured to select a working frequency of the mobile phone antenna according to the control command;
for the present embodiment, the coil unit 202 includes a mobile phone coil, at least two sets of adaptation circuits; all the adaptive circuits are simultaneously connected with the mobile phone coil, the coil unit selects one of the adaptive circuits from the groups according to the control command, and the working frequency of the selected adaptive circuit combined with the mobile phone coil is the working frequency of the mobile phone antenna. The adaptation circuit comprises an inductor and a capacitor; the value of the inductor and the value of the capacitor are fixed and unchanged.
And the NFC chip 203 is used for completing payment after the working frequency of the mobile phone antenna is matched with the working frequency of the acceptance terminal.
Correspondingly, based on the above working principle, the present invention further provides a method for adjusting the working frequency of the mobile phone antenna, as shown in fig. 3. The method comprises the following steps:
step 301): generating a control command according to the working frequency of the acceptance terminal;
step 302): selecting the working frequency of the mobile phone antenna according to the control command;
step 303): and after the working frequency of the mobile phone antenna is matched with the working frequency of the acceptance terminal, the NFC chip of the mobile phone completes payment.
In practical application, a user does not need to know the working frequency of the acceptance terminal, when the situation that the mobile phone is not matched with the acceptance terminal occurs, the user actively adjusts the working frequency of the mobile phone antenna, and after multiple attempts, the working frequency of the mobile phone matched with the acceptance terminal can be achieved. The working frequency of the adjusted mobile phone antenna is between 13MHz and 18 MHz. Such as: the operating frequency of the originally shipped mobile phone antenna is 13.2MHz, and due to aging of the acceptance terminal and other reasons, the current operating frequency of the acceptance terminal is 17.6 MHz. When the mobile phone antenna is used, the working frequency of the mobile phone antenna cannot be matched with the actual working frequency of the receiving terminal.
For the technical scheme, before the mobile phone leaves factory, a plurality of groups of adaptation circuits are configured in advance, such as: 3 sets of adaptation circuits. The working frequency generated by combining each group of the adaptive circuits and the mobile phone coil is respectively 14.8MHz, 15.9MHz and 17.3MHz, and the working frequency of the mobile phone antenna is 13.2MHz under the condition that no adaptive circuit exists before. Then, through APP selection, the operating frequency of the mobile phone antenna can be one of four values, namely 13.2MHz, 14.8MHz, 15.9MHz and 17.3MHz, and one operating frequency matched with the acceptance terminal is selected from the four values.
For the embodiment, in the technical scheme, one group of the adaptive circuits is selected from the multiple groups of the adaptive circuits configured in advance through the APP, and the adaptive circuits are combined with the mobile phone coil, so that the actual working frequency of the mobile phone antenna is changed to 17.3MHz, and at the moment, the working frequency of the mobile phone antenna is successfully matched with the actual working frequency of the acceptance terminal, and mobile phone payment can be realized.
According to the technical scheme, the working frequency of the antenna can be dynamically adjusted after the mobile phone leaves a factory, so that the mobile phone can work in a wider field, and the mobile phone is not only adapted to diversified acceptance terminals in the market by using one frequency.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
