In the embodiment of the application, the field intensity sensing circuit detects external field intensity data, and the processor determines a target communication position with the optimal communication effect with external read-write equipment based on the external field intensity data; further, a target conductive valve is opened and a liquid driver is controlled to drive conductive liquid into a target antenna mold connected to the target conductive valve to form an NFC antenna in the target antenna mold. Therefore, the NFC antenna is positioned at the target communication position and the communication effect of the external read-write equipment is optimal, the communication success rate between the NFC antenna of the electronic equipment and the external read-write equipment can be improved, namely the NFC card swiping success rate is improved, and the using convenience of the NFC function is further improved.
In an alternative embodiment, the number of the target antenna molds 134 is M; as shown in fig. 4, the control component 130 includes a first antenna feeding point 135, M second antenna feeding points 136, and a feeding point switcher (not shown) electrically connected to the M second antenna feeding points 136, where M is a positive integer less than or equal to N;

The first antenna feed point 135 continues to obtain an electrical signal.
The M second antenna feed points 136 are located at the second ends of the M NFC antennas, respectively, and the M second antenna feed points 136 are connected to a feed point switch, where the feed point switch can select at least one second antenna feed point (i.e., the target second antenna feed point) to obtain an electrical signal.
After the target second antenna feeding point obtains the electric signal, the NFC antennas respectively connected to the first antenna feeding point 135 and the target second antenna feeding point communicate with the external reader/writer device under the cooperation of the first antenna feeding point 135 and the target second antenna feeding point.
The feeding point switch selects a different second antenna feeding point 136 to obtain an electric signal, so that the NFC antennas at different positions can be switched to communicate with external read-write equipment. In this embodiment, the processor 120 controls the feeding point switcher to select the target second antenna feeding point located at the target communication position based on the target communication position to obtain an electrical signal to cooperate with the first antenna feeding point 135, so as to trigger the NFC antenna located at the target communication position to communicate with the external reader/writer device.
In another alternative embodiment, as shown in fig. 5, the control assembly 130 includes a first telescopic mechanism 137 and a second telescopic mechanism 138 respectively disposed at two sides of the liquid storage bin 131; the first telescopic mechanism 137 and the second telescopic mechanism 138 are connected with the liquid storage bin 131;

In this embodiment, a first telescopic mechanism 137 and a second telescopic mechanism 138 are respectively disposed on the upper and lower sides of the liquid storage bin 131. The first telescopic mechanism 137 and the second telescopic mechanism 138 are disposed along the up-down direction, so as to drive the liquid storage bin 131 to move along the up-down direction.
Note that, in this embodiment, the "up" and "down" directions are all directions shown in fig. 4.
When the target communication position is located above the current position of the liquid storage bin 131, the first telescopic mechanism 137 may be located below the liquid storage bin 131, and the second telescopic mechanism 138 may be located above the liquid storage bin 131; the first telescopic mechanism 137 extends and the second telescopic mechanism 138 retracts to drive the liquid storage bin 131 to move upwards to reach the target communication position;

The matching circuit 140 is used for adjusting load power and suppressing signal reflection, so that the NFC antenna is impedance matched with the external read-write device, and the communication success rate is improved.
Because NFC antennas are located in different positions, impedance matching values are different from each other under the influence of factors such as environment, signal transmission distance and the like. Thus, different matching sub-circuits 141 are required at different communication locations.
The matching sub-circuit 141 may include devices such as capacitors, inductors, etc., and different matching sub-circuits 141 may have different impedance values through different series-parallel relationships and/or different parameter values.
In this embodiment, the NFC antennas may be configured in different communication positions in advance, and each matching sub-circuit 141 is used to test in each communication position, and the matching sub-circuit 141 with the best test communication effect is the matching sub-circuit 141 corresponding to the communication position.
In this way, after determining the target communication position, the processor 120 controls the switcher 142 to electrically connect the NFC antenna with the target matching sub-circuit corresponding to the target communication position, so as to improve the communication success rate between the NFC antenna and the external read-write device, that is, improve the NFC card swiping success rate, and further improve the convenience of using the NFC function.

controlling a target second antenna feed point to obtain an electric signal through the feed point switcher so as to be matched with the first antenna feed point, and triggering an NFC antenna connected with the target second antenna feed point; and the NFC antenna connected with the target second antenna feed point is positioned at the target communication position.
The first antenna feeding points are located at the centers of the N antenna molds, and the N antenna molds are distributed in a divergent surrounding manner with the first antenna feeding points as the center, as shown in fig. 4, that is, the first antenna feeding points are located at the intersection of the first ends of the NFC antennas formed in the N antenna molds. The first antenna feed point continues to obtain an electrical signal.
The M second antenna feed points are respectively located at the second ends of the M NFC antennas, and are connected with the feed point switcher, and the feed point switcher can select at least one second antenna feed point (namely a target second antenna feed point) to obtain an electric signal.
After the target second antenna feeding point obtains the electric signal, the NFC antennas respectively connected with the first antenna feeding point and the target second antenna feeding point communicate with external read-write equipment under the cooperation of the first antenna feeding point and the target second antenna feeding point.
The feeding point switcher selects different feeding points of the second antenna to obtain electric signals, so that NFC antennas at different positions can be switched to communicate with external read-write equipment. In this embodiment, the processor controls the feeding point switcher to select the target second antenna feeding point located at the target communication position based on the target communication position to obtain an electrical signal to cooperate with the first antenna feeding point, and triggers the NFC antenna located at the target communication position to communicate with the external reader-writer device.
In another alternative embodiment, the method is applied to the electronic device of the near field communication module shown in fig. 5; the method further comprises the steps of:
the first telescopic mechanism is driven to extend and the second telescopic mechanism is driven to retract, so that the liquid storage bin is adjusted to drive the target antenna die to move to the target communication position.
In this embodiment, a first telescopic mechanism and a second telescopic mechanism are respectively arranged on the upper side and the lower side of the liquid storage bin. The first telescopic mechanism and the second telescopic mechanism are arranged along the up-and-down direction so as to drive the liquid storage bin to move along the up-and-down direction.
Note that, in this embodiment, the "up" and "down" directions are all directions shown in fig. 4.
When the target communication position is above the current position of the liquid storage bin, the first telescopic mechanism can be positioned below the liquid storage bin, and the second telescopic mechanism can be positioned above the liquid storage bin; the first telescopic mechanism stretches out and the second telescopic mechanism retracts to drive the liquid storage bin to move upwards to reach a target communication position;
when the target communication position is positioned below the current position of the liquid storage bin, the first telescopic mechanism can be positioned above the liquid storage bin, and the second telescopic mechanism can be positioned below the liquid storage bin; the first telescopic mechanism extends out and the second telescopic mechanism retracts back to drive the liquid storage bin to move downwards to reach a target communication position.

and controlling the NFC antenna to be electrically connected with a target matching sub-circuit corresponding to the target communication position through the switcher.
The matching circuit is used for adjusting load power and inhibiting signal reflection, so that the NFC antenna is matched with the impedance of external read-write equipment, and the communication success rate is improved.
Because NFC antennas are located in different positions, impedance matching values are different from each other under the influence of factors such as environment, signal transmission distance and the like. Thus, different matching sub-circuits are required at different communication locations.
The matching sub-circuits may include devices such as capacitors and inductors, and different matching sub-circuits may have different impedance values through different series-parallel relationships and/or different parameter values.
In this embodiment, the NFC antenna may be configured in advance at different communication positions, and each matching sub-circuit is used to test at each communication position, and the matching sub-circuit with the best test communication effect is the matching sub-circuit corresponding to the communication position.
Thus, after determining the target communication position, the processor controls the switcher to electrically connect the NFC antenna with the target matching sub-circuit corresponding to the target communication position, so that the communication success rate between the NFC antenna and external read-write equipment is improved, namely the NFC card swiping success rate is improved, and the using convenience of NFC functions is further improved.
