There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are the present invention
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
These accompanying drawings obtain other accompanying drawings.
Fig. 1 be it is of the present invention it is a kind of judge NFC antenna whether the structured flowchart of the terminal of loose contact；
Fig. 2 is a kind of workflow diagram of terminal of the present invention.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Refer to Fig. 1, The embodiment provides it is a kind of judge NFC antenna whether the terminal of loose contact, its wrap
NFC antenna 1, NFC receiving circuits 2, NFC chip 3 and processor 4 are included, the present embodiment is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the input/output terminal of NFC antenna 1 is electrically connected with the first input/output terminal of NFC receiving circuits 2,
When NFC antenna 1 detect extraneous POS close to or other card-reading apparatus close to when, due to electromagnetic induction, NFC antenna 1 can be produced
Raw aerial signal, the aerial signal can be converted into electric signal into NFC receiving circuits 2.Wherein, NFC antenna 1 can be arranged on
On the rear lid case of terminal.
Second input/output terminal of NFC receiving circuits 2 receives leads ends with the signal of NFC chip 3 and is electrically connected with by one
Part 5 is electrically connected.As preferably embodiment, the electric connection part 5 could be arranged to shell fragment, naturally it is also possible to for other companies
Fitting, non-the present embodiment is limited.During work, it can be transported to through the converted electric signal of NFC receiving circuits 2 by shell fragment
Handled in NFC chip 3.
The EBI end of processor 4 electrically connects to carry out data interaction with the EBI end of NFC chip 3.In addition, place
Manage device 4 and be provided with a GPIO mouthfuls, described GPIO mouthfuls electrically connects and (draw with NFC chip 3 and the tie point being electrically connected between part 5
One branch road is connected on processor), processor 4 can be gathered by GPIO mouthfuls and be transported to NFC chip 3 by electric connection part 5
Electric signal, and judge whether the electric signal collected is normal NFC signals or interference signal；The telecommunications collected when judgement
Number be normal NFC signals when, then show that NFC antenna 1 is contacted well；When the electric signal for judging to collect is interference signal,
Then show the loose contact of NFC antenna 1.When it is implemented, based on above-mentioned judgement, corresponding NFC application software can be developed to sentencing
Disconnected result is shown or directly judged result is shown by a display module.
As preferred embodiment, in practical operation, the processor 4 can be further used for by obtaining telecommunications
Number magnitude of voltage judge whether the electric signal collected is normal NFC signals or interference signal.Wherein, when electric signal
When magnitude of voltage is more than or equal to predetermined voltage threshold, then the electric signal collected is judged as normal NFC signals, NFC antenna 1 connects
Touch good；When the magnitude of voltage of electric signal is less than predetermined voltage threshold, then the electric signal collected is judged as interference signal, NFC
The loose contact of antenna 1.Wherein, the type of electric signal is judged by the magnitude of voltage of electric signal can effectively improve the accurate of judgement
Degree.
For normally contacting good NFC antenna, aerial signal is relatively good, and the magnitude of voltage of the electric signal passed over also can
Than larger, if contact is bad, or abnormal contact, in this case, the magnitude of voltage of the electric signal passed over can compare
It is small.For example, here by taking a magnitude of voltage 1.2V as an example, when NFC antenna contact is relatively good, the electric signal passed over
Magnitude of voltage be greater than 1.2V, when NFC antenna loose contact, the magnitude of voltage of the electric signal passed over can be less than
1.2V, or even only 0.01V (voltage of this very little just may be considered the interference signal in the case of being not in contact with), due to
The limited precisions of GPIO for voltage signal, these small signals in itself can directly be ignored, and electricity can be set in software
The signal that the electric signal that pressure value is less than 1.2V is produced when being exactly antenna loose contact, needs to check antenna, if electric this when
Pressure value is more than 1.2V, it is believed that be that its linear contact lay is good.

(3) when the electric signal for judging to collect is normal NFC signal, the NFC antenna 1 is contacted well；
(4) when the electric signal for judging to collect is interference signal, the loose contact of NFC antenna 1.
As preferred embodiment, in step (2), the processor 4 judges whether the electric signal collected is just
The step of normal NFC signals or interference signal, specifically includes：
Whether it is normal NFC signals or interference that the electric signal collected is judged by obtaining the magnitude of voltage of electric signal
Signal；
When the magnitude of voltage of electric signal is more than or equal to predetermined voltage threshold, then judge the electric signal collected to be normal
NFC signals, the NFC antenna 1 is contacted well；
When the magnitude of voltage of electric signal is less than predetermined voltage threshold, then the electric signal collected is judged as interference signal, institute
State NFC antenna loose contact.
As shown in Fig. 2 showing a kind of workflow diagram of terminal in figure, it comprises the following steps：
