Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.

Referring to fig. 2, a method for controlling an NFC device according to the present invention includes the steps of:

step 201: the method comprises the steps that an NFC device detects the signal intensity and duration of an NFC signal, and the NFC signal is generated through electromagnetic coupling between the NFC device and an NFC control device;

it should be noted that Near Field Communication (NFC) is a short-range high-frequency radio technology, and the transmission speed is 106 Kbit/s, 212 Kbit/s or 424 Kbit/s when operating within a distance of 10 cm at a frequency of 13.56 MHz. At present, NFC has passed through to be ISO/IEC IS 18092 international standard, EMCA-340 standard and ETSITS 102190 standard, and IS widely used. NFC evolved from contactless Radio Frequency Identification (RFID) and is downward compatible with RFID. The NFC technology does not need to set, discover or pair the two connected devices in advance, and the two devices can be quickly and automatically connected only by being close to a certain distance, so that the processes of searching, pairing and the like of the existing wireless communication technologies such as WiFi and Bluetooth are omitted.

When the NFC target device works in the passive mode, the NFC initiator device needs to provide a radio frequency field (RF-field) in the whole communication process, the NFC target device does not generate the RF field, data are transmitted back to the NFC initiator device at the same speed by using a load Modulation (L load Modulation) technology, and when the NFC target device works in the active mode, the NFC initiator device and the NFC target device both generate own RF fields so as to carry out communication.

In this embodiment, the types of the NFC device and the NFC control device may be any electronic product with an NFC function, for example, the NFC control device may be a mobile terminal with an NFC function, a watch with an NFC function, or the like, and the NFC device may be a mobile terminal with an NFC function, a sound, an air conditioner, a remote controller, or the like.

Specifically, the Signal Strength refers to the Strength of the radio frequency Signal, and is generally characterized by the transmission power of the radio frequency Signal (or by parameters such as field Strength and voltage), and the measurement units include milliwatt (mW), decibel milliwatt (dBm), rssi (received Signal Strength indicator), percentage, and the like, wherein the dBm unit represents decibel number relative to 1 milliwatt; RSSI is a mechanism defined by IEEE for measuring the strength of the radio frequency signal received by the wireless network card, and has a value of 0-255, but for different manufacturers, the RSSI is not set to be 256 levels, but the RSSI _ MAX is provided; the percentage represents the ratio of the RSSI value of the particular signal to the reference signal.

Step 202: judging whether the duration is greater than or equal to a preset first duration threshold;

the first duration threshold is used to avoid the occurrence of false determination, and specifically, the first duration threshold may be set to 1 second or any other size.

Further, the step 202 further includes:

the NFC equipment judges whether the duration is less than or equal to a preset second duration threshold value;

For example, the first duration threshold may be set to 1s, the second duration threshold may be set to 3s, and when the duration is between [1s, 3s ], the NFC device determines that the NFC signal is valid. By judging whether the duration is between the first duration threshold and the second duration threshold, the situation of misjudgment caused by the fact that two NFC devices are close to each other for a long time can be avoided.

Step 203: and the NFC equipment converts the signal intensity of the NFC signal into a control signal grade, and controls a predefined controlled item according to the control signal grade.

In an embodiment of the present invention, the predefined controlled item may be any one of parameters of brightness, volume, temperature, and the like of the NFC device.

In another embodiment of the present invention, before the step 201, the method further comprises the steps of:

For example, the NFC device is a mobile phone with an NFC function, and it is predefined that when the mobile phone is in a screen-off state, the controlled item is a ringtone volume, and when the mobile phone is in a screen-on state, the controlled item is a screen brightness.

the NFC equipment defines a plurality of controlled items in advance;

before the step 203, the method further comprises the steps of:

the user is notified of the selection of the number of controlled items.

For example, the NFC device is a mobile phone with an NFC function, the controlled items include parameters such as brightness and volume, and when the mobile phone determines that an NFC signal generated by electromagnetic coupling between the mobile phone and the NFC control device is valid, a notification message is displayed on a mobile phone screen or in a notification bar, and a plurality of controlled items for a user to select are listed, and one of the controlled items is selected by the user for control.

Further, in step 203, the step of converting the signal strength of the NFC signal into a control signal level by the NFC device specifically includes:

the NFC equipment predefines the corresponding relation between the signal intensity of the NFC signal and the grade of the control signal in different communication modes;

It should be noted that, when the NFC device operates in the active mode, the NFC device and the NFC control device both need to provide a radio frequency field to generate a coupling magnetic field, and when the NFC device operates in the passive mode, the NFC device does not generate the radio frequency field, so that when the NFC device operates in the active mode, the signal strength of the NFC signal generated by coupling the NFC device and the NFC control device is greater than the signal strength of the NFC signal generated by coupling the NFC device and the NFC control device when the NFC device operates in the passive mode. By presetting different corresponding relations between the signal intensity of the NFC signal and the control signal grade under the active mode and the passive mode, the signal intensity of the NFC signal can be more accurately converted into the corresponding control signal grade.

For example, assuming that the control signal levels include ten levels of one to ten, the NFC device predefines two NFC signals that differ by one control signal level per phase, with signal strengths differing by 3dBm and 1dBm in the active mode and in the passive mode; the signal strength of the NFC signal corresponding to each level of the control signal in the active mode and the passive mode may also be predefined.

Further, the signal strength of the NFC signal generated by the NFC device and the NFC control device coupled varies with the distance and angle between the NFC device and the NFC control device. Therefore, the controlled item can be controlled by adjusting the signal strength of the NFC signal generated by coupling the NFC device and the NFC control device by controlling the distance or angle between the NFC device and the NFC control device.

In an embodiment of the present invention, when the NFC device is a remote controller, the step of controlling the predefined controlled item according to the level of the control signal specifically includes:

and the NFC equipment sends a control signal to the control equipment of the NFC equipment according to the control signal grade and controls the predefined controlled item.

The control signal can be signals such as WiFi, Bluetooth and infrared, and the control equipment can be equipment such as a television and an air conditioner.

Fig. 3 and 4 are schematic diagrams of two application scenarios of the present invention, respectively. As shown in fig. 3, a mobile terminal with an NFC function is used to approach an air conditioner with an NFC function, assuming that a predefined controlled item is an adjustment temperature of the air conditioner, the air conditioner sets a control level of its own adjustment temperature according to a signal intensity of an NFC signal generated by electromagnetic coupling between the mobile terminal and the air conditioner, and can adjust the signal intensity of the NFC signal generated by both coupling by adjusting a distance or an angle between the mobile terminal and the air conditioner;

as shown in fig. 4, a mobile terminal with an NFC function is used to be close to a remote controller with an NFC function, a predefined controlled item is assumed to be the volume of a television, the remote controller sends a corresponding infrared remote control signal to adjust the control level of the volume of the television according to the signal intensity of an NFC signal generated by electromagnetic coupling between the mobile terminal and the remote controller, so as to adjust the volume of the television, and the signal intensity of the NFC signal generated by coupling between the mobile terminal and the remote controller can be adjusted by adjusting the distance or angle between the mobile terminal and the remote controller.
