With the development and popularization of the NFC technology, the NFC technology is increasingly used in the mobile terminal at present, so that the mobile terminal can be used as a bus card, a bank card and the like, a user does not need to carry various cards completely, the mobile terminal carries out mobile payment, card swiping and even point-to-point file transmission, and great use convenience is brought to the user. The NFC operation mode is divided into a passive mode and an active mode. The NFC initiator (also called master) in the passive mode needs a power supply device, the master provides a radio frequency field by using the energy of the power supply device and transmits data to the NFC target (also called slave), and the transmission rate needs to be selected from one of 106kbps, 212kbps and 424 kbps. The slave device does not generate a radio frequency field, so that a power supply device is not needed, the radio frequency field generated by the master device is converted into electric energy, the circuits of the slave device are powered, data sent by the master device are received, and the data of the slave device are transmitted back to the master device at the same speed by using a load modulation technology. Because NFC is a wireless technology, need through radio wave transmission signal, also need receive the radio wave of corresponding frequency channel, and whether NFC's signal reception, send and directly rely on the NFC antenna smoothly, for the NFC result of use is better, generally establish fingerprint antenna in the back lid when mobile terminal manufacturer in mobile terminal concrete use to make antenna area the biggest, the communication effect is best, the antenna that sets up on the back lid is connected with the mobile terminal mainboard through the metal contact on the back lid. When the card reader is operated through NFC, the card reader adopts a polling graph mode to search various card types supported by the NFC within the antenna range until the card types are searched, so that more energy is consumed, and the battery endurance is influenced. Since the power consumption of NFC is accumulated to be high when operating for a long time, it is necessary to monitor the power supply of NFC to avoid consuming more energy for a long time. In addition, in the use process of the actual mobile terminal, the NFC use frequency is lower, the NFC use frequency is only used once in card swiping and payment in one day, and the NFC use frequency is not used in other days. Therefore, the present invention provides a power supply control method and power supply control for an NFC chip of a mobile terminal to solve the above problems.
The NFC (near field communication) technology is a short-distance high-frequency radio technology, combines the functions of an induction card reader, an induction card and point-to-point on a single chip, and can perform identification and data exchange with compatible equipment in a short distance. The working frequency is 13.56MHz, and the technology can be used as airport boarding verification, entrance key of buildings, traffic one-card communication, credit card, payment card and the like.

Exemplary method
In a first aspect, the present invention provides a power supply control method for an NFC chip of a mobile terminal, including the following steps:
step S01, detecting the use time of the NFC chip;
step S02, determining the power supply state of the NFC chip within a preset time range according to the use time;
and step S03, controlling the power supply of the NFC chip according to the power supply state.
Specifically, in this embodiment, before step S01, the method further includes the following steps:
and S001, when the mobile terminal is started, closing the power supply switch to electrify the NFC chip and the mobile terminal. When the power supply switch is closed, the NFC chip is in a power supply state; when the power supply switch is closed, the NFC chip is in a power-off state.
And S002, performing initialization configuration on the NFC chip to enable the NFC chip to work normally.
Specifically, in step S01, the types of the timers for detecting the usage time of the NFC chip by the timer include an electromagnetic dot timer, an electric spark timer, a stick timer, a parking timer, a reaction timer, an amplification timer, a windows timer, and the like. Electromagnetic and spark strike timers are most common. The timer is counted from zero, the triggering is started, and the output time is the time which passes after the timer is started until the timer is stopped, so that the using time of the NFC chip is obtained. Step S01 also includes presetting a preset threshold of the timer. In this embodiment, the preset threshold is 100 minutes. Of course, the preset threshold may be set to other values, and the present invention is not limited thereto. And setting the time for starting the timer and performing communication detection by the NFC chip through a preset threshold set by the timer. In this embodiment, the preset threshold is set for a long time, and at this time, the NFC chip is likely not to perform communication, so that the timer is started after the preset threshold, so as to adjust the power supply current of the NFC chip.
Referring to fig. 2, the step S02 includes the following steps:
step S21, when the service time exceeds a preset threshold, a timer is started;
step S22, detecting voltage data of the NFC chip within a preset time of the timer, and determining a power supply state of the NFC chip according to the voltage data.
In step S21, specifically, the timer is disposed in the controller of the NFC chip, and the timer starts timing after being powered on, and the contact operates when the timing time reaches a preset time. The length of the preset time can be adjusted by changing the resistance value of a variable resistor in the electronic circuit, and the timer is reset when the power supply is disconnected. The timer is set for a time, subtraction is carried out, and output is triggered after the set event is finished. The timer functions relatively more preferentially to calculate time, and the timer functions to alert time.
Referring to fig. 3, in step S22, the method specifically includes the following steps:
and S221, setting the power supply current of the NFC chip to be a preset value within the preset time of the timer. In this embodiment, preferably, the preset time is 10 seconds. Of course, the preset time may be set to other values, and the present invention is not limited thereto. The preset time set by the timer is convenient for quickly detecting the power supply voltage of the NFC chip. Preferably, the preset value of the supply current of the NFC chip is set to 100 milliamperes. Of course, the preset value of the supply current of the NFC chip may be set to other values, and the present invention is not limited thereto.
S222, reading the power supply voltage of the NFC chip through the analog-to-digital conversion module. Since a large current flows into the NFC chip in a power supply state, the read supply voltage of the NFC chip is inaccurate, and therefore, the supply current of the NFC chip is read when the supply current of the NFC chip is set to a preset value, and the obtained supply voltage is accurate.
And S223, when the power supply voltage of the NFC chip is within a preset range, the power supply state of the NFC chip is a normal power supply state.
Therefore, the power supply voltage of the NFC chip when the power supply current is a preset value can be measured, whether the power supply state of the NFC chip is abnormal or not can be further judged, the power supply condition of the NFC chip after long-time use can be monitored, and the power supply mode of the NFC chip can be further controlled.
In step S03, specifically, the NFC chip is controlled differently according to different power supply states. And when the power supply state is an abnormal power supply state, setting the power supply current of the NFC chip to be a preset value or disconnecting the power supply of the NFC chip. And when the power supply state is the normal power supply state, setting the preset value as a normal value, and recovering the normal power supply of the NFC chip.

Further, the power supply state detection module 20 further includes a timer for setting a preset time for detecting the power supply state. In this embodiment, preferably, the preset time is 10 seconds. Of course, the preset time may be set to other values, and the present invention is not limited thereto. The power supply state detection module further comprises an analog-to-digital conversion module, and the analog-to-digital conversion module is used for detecting the power supply voltage of the NFC chip when the power supply current is a preset value.
The NFC chip power supply control module 30 is configured to control power supply to the NFC chip according to a power supply state. Specifically, when the power supply state is an abnormal power supply state, the power supply current of the NFC chip is kept at a preset value or the power supply of the NFC chip is disconnected; and when the power supply state is the normal power supply state, the preset value setting is released, and the normal power supply of the NFC chip is recovered. Preferably, the preset value of the supply current of the NFC chip is set to 100 milliamperes. Of course, the preset value of the supply current of the NFC chip may be set to other values, and the present invention is not limited thereto.
