The application will be further described by the description of embodiments with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart of a preferred embodiment of a communication control method of an NFC reader of a mobile terminal according to the present application. The method comprises the following steps:
and S10, when the NFC starts a card reading mode, starting an input clock of the NFC, setting the clock frequency corresponding to the NFC as a first preset frequency, and controlling the NFC to execute card detection.
Specifically, the input clock includes two periods, one is the period of the input clock itself, and is denoted as period one; the other period is a period when the input clock is combined with the NFC and the NFC is in an interval time in the working state, and is recorded as a period two. In the second period, the frequency of the input clock executed when the NFC is in the card detection state is different from the frequency of the input clock executed when the NFC is in the interval time, and the frequency of the input clock executed in the second period is recorded as a clock frequency, that is, the clock frequency corresponds to the NFC. The first preset frequency is a frequency preset and stored in the NFC, and the first preset frequency is a frequency executed by the input clock when the NFC detects the card. When the NFC starts a card reading mode, an input clock of the NFC is started, the clock frequency of the input clock is set to be a first preset frequency, and when the input clock executes the first preset frequency, the NFC performs card detection. In this embodiment, the first preset frequency is 12MHz, and the NFC performs card detection according to the 12MHz executed by the input clock.
Further, since the NFC has three working modes, namely a card analog mode, a point-to-point mode and a card reading mode, the NFC needs to receive a related external instruction to start the card reading mode and detect the card. In an embodiment of the present application, as shown in fig. 2, when the NFC starts the card reading mode, starting an input clock of the NFC and setting a clock frequency corresponding to the NFC to a first preset frequency, and controlling the NFC to perform card detection specifically includes:
s11, when the fact that a user starts NFC card reading communication control is detected, starting NFC and configuring NFC into a card reading communication mode;
specifically, when a user inputs an instruction for starting NFC to a terminal and configuring the NFC into a card reading mode, so as to control the terminal to start NFC card reading control, the terminal controls to start NFC and configures the NFC into the card reading mode.
S12, starting an NFC input clock and acquiring a first preset frequency corresponding to the card reading mode when the NFC is configured to the card reading mode, and setting the first preset frequency as the clock frequency corresponding to the NFC.
Specifically, when the opened NFC is configured to be in a card reading mode, an input clock of the NFC is opened, the first preset frequency is obtained, the first preset frequency is set to be a clock frequency of the input clock, the input clock executes the first preset frequency, and meanwhile the NFC detects a card according to the first preset frequency. That is, the input clock performs a first preset frequency at the time of card detection by NFC.
And S20, when the card detection is finished, setting the clock frequency to be a second preset frequency, and monitoring the duration of the card detection.
Specifically, a first time is preset, wherein the first time is the longest time period for card detection by NFC. And if the NFC detects the card at any time point in the first time range, ending the card detection of the NFC. If the NFC does not detect the card in the first time, the card detection of the NFC is finished at the same time of finishing the first time. When the NFC ends card detection due to either of the above two cases, the application sets the clock frequency to a second preset frequency. And starts listening for the duration of the end of the card detection at the same time as the end of the card detection. The duration takes the time when the NFC ends the card detection as a starting point and takes the time when NFC is no longer in a state of ending the card detection as an end point.
As shown in fig. 3, when the card detection is finished, setting the clock frequency to a second preset frequency, and monitoring the duration of the card detection is finished specifically includes:
s21, when card detection is finished, randomly generating a second preset frequency for configuring the clock frequency;
s22, configuring the second preset frequency as a clock frequency, and monitoring the duration of the end of card detection.
Specifically, the second preset frequency is one frequency randomly generated by a random module in the terminal, and the second preset frequency is more than 1MHz. At the end of the card detection, a second preset frequency greater than 1MHz is randomly generated by the terminal and configured as a clock frequency such that the input clock performs the second preset frequency. According to the application, the second preset frequency with the random number characteristic is randomly generated and used, so that the frequency related to NFC of the input clock when the NFC is not used for card detection is different from the first preset frequency, and the problem that the second preset frequency is not called by a module except NFC in the terminal is avoided, and the influence of the frequency in the double period of the input clock on other modules is reduced.
Further, the configuring the second preset frequency as a clock frequency, and monitoring the duration of the card detection end specifically includes:
configuring the second preset frequency as a clock frequency, and starting a timer configured with the preset duration;
monitoring the duration of the detection ending through the timer.
Specifically, the preset duration is preset in the timer, and the timer is timed according to the preset duration. In the present application, the preset time period may be 1s, 2s, 3s, or the like. The timer starts to start counting at the same time as the end of the card detection, and listens for the duration of the end of the detection while counting. That is, at the end of the card detection, the input clock is changed from executing the first preset frequency to executing the second preset frequency, and at the same time, the timer starts to time and listens for the duration of the end of the card detection.
Further, when the duration time reaches a preset duration time, repeatedly starting an input clock of the NFC and setting a clock frequency corresponding to the NFC to a first preset frequency until the card reading communication mode is finished specifically includes:
when the timer times out, judging that the duration reaches a preset duration;
and repeatedly starting an NFC input clock and setting the clock frequency corresponding to the NFC to a first preset frequency until the card reading mode is finished.
Specifically, the timer timeout means that when the timer is timed out according to the preset duration, the input clock is still executing the second preset frequency. And when the timer is overtime, judging that the duration reaches the preset duration. And when the timer is overtime, repeatedly starting an NFC input clock and resetting the clock frequency corresponding to the NFC to a first preset frequency until the card reading mode is ended.
When the card detection is finished, setting the clock frequency to a second preset frequency, and configuring a preset execution period of the second preset frequency;
specifically, the preset execution period is an execution period of the second preset frequency, that is, the input clock starts to execute the second preset frequency while the clock frequency of the input clock is converted from the first preset frequency to the second preset frequency, and the input clock executes the second preset frequency of the second preset period.
While the input clock executes the second preset frequency, monitoring an execution period of the input clock executing the second preset frequency and a duration of the card detection ending.
Further, when the execution period of the clock is monitored to reach a preset execution period, the clock is closed, wherein the preset execution period is randomly generated.
Specifically, the preset execution period and the second preset frequency are both randomly generated by the terminal, and the preset execution period satisfies less than 100 and is expressed as a random number. And closing the input clock when the execution period of the clock reaches a preset execution period, so that the input clock does not execute the first preset frequency or the second preset frequency. The precondition that the execution period of the input clock can reach the preset execution period is that the timer has not yet ended, that is, when the input clock has ended executing the preset execution frequency, the timer has not yet ended counting the preset duration. And when the time taken by the input clock to execute the second preset frequency of the preset execution period is smaller than the preset duration, closing the input clock.
Further, when the time taken for the input clock to execute the second preset frequency of the preset execution period is longer than the preset duration set in the timer, the working state of the NFC is changed when the timer reaches the preset duration.
And S30, when the duration time reaches the preset duration time, repeatedly starting an NFC input clock and setting the clock frequency corresponding to the NFC to be a first preset frequency until the card reading communication mode is ended.
As shown in fig. 4, it specifically includes:
s31, detecting whether the execution period of the input clock reaches a preset execution period or not when the duration reaches a preset duration;
and S32, stopping the NFC input clock when the preset execution period is not reached, starting the NFC input clock, and setting the clock frequency corresponding to the NFC to be a first preset frequency until the card reading mode is ended.
Specifically, when the preset execution period is not reached, the input clock does not execute the second preset frequency of the preset execution period when the timer has counted for a preset duration. Resetting the timer, closing the timer, repeatedly starting an NFC input clock, starting the NFC input clock, and setting the clock frequency of the NFC input clock to a first preset frequency until the card reading mode is ended.
