Embodiment
The invention provides a kind of near field communication (NFC) terminal with electricity-saving function, clearer, clear and definite for making purpose of the present invention, technical scheme and effect, below with reference to accompanying drawing and give an actual example that the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
See also Fig. 1, the near field communication (NFC) terminal with electricity-saving function that the embodiment of the invention provides has the NFC module can realize mobile payment function, and it comprises range sensor and baseband processor, and described range sensor is connected with baseband processor.
Whether described range sensor is used for real-time detection has the NFC equipment that matches with near field communication (NFC) terminal close, and exports interrupt signal to baseband processor when the distance of NFC equipment and near field communication (NFC) terminal reaches threshold value.
Described baseband processor is used to respond described interrupt signal, activates the NFC module of near field communication (NFC) terminal and carries out the NFC function.Described range sensor, NFC module are connected with baseband processor respectively.In the specific implementation, embodiment of the invention NFC module is set to power down mode, only just activates the NFC module at the NFC equipment that pairing is arranged when the NFC terminal, thereby has reduced the extra power consumption of battery, has reached purpose of power saving.
Wherein, the threshold value of range sensor can be passed through software set, and its size depends on the transmitting power size of transmit leg and recipient's receiving sensitivity size.The present invention is according to the actual conditions of NFC terminal, and the threshold value of setpoint distance transducer is 10CM.
In a further embodiment, the present invention is provided with the anti-shake mechanism of interruption and prevents the baseband processor false triggering, sees also Fig. 2, and it is the structured flowchart of the present invention's first preferred embodiment.
In described range sensor, be provided with anti-shake register, the distance that this anti-shake register is used for detecting NFC equipment and near field communication (NFC) terminal in the range sensor continuous several times is in the threshold value scope time, and the command range transducer is exported effective interrupt signal and given baseband processor.After baseband processor receives effective interrupt signal that range sensor sends, just really activate the FNC module.
In the present embodiment, anti-shake register is consecutively detected the number of times of distance in the threshold value scope of NFC equipment and near field communication (NFC) terminal can be by software set, its concrete number of times depends on the ADC(Analog-to-Digital Converter of anti-shake time T and range sensor inside, A/D converter) sampling interval Interval, be T=N*INTERNVAL, wherein anti-shake time T can be provided with 50ms, its size only needs to shield invalid interrupt signal, can not cause NFC equipment pairing overlong time to get final product again.
