Based on the above hardware structure, an embodiment of the NFC communication control method of the present invention is provided.
In an embodiment of the NFC communication control method, referring to fig. 2, the NFC communication control method includes:
step S10, if the NFC communication request of the electronic equipment is detected, acquiring the equipment information of the electronic equipment based on the NFC wireless communication;
step S20, acquiring first charging request information of the equipment information, and determining first charging radio frequency power according to the first charging request information;
step S30, a preset charging rf field is started according to the first charging rf power, so as to charge the electronic device.
The NFC communication control method is mainly applied to power supply equipment, the equipment related in the method can be a mobile terminal (such as a mobile phone, a charger baby, a tablet computer, a charging power supply and the like), wearable equipment (such as an intelligent bracelet, a charger baby, a TWS earphone, a charging box, intelligent glasses, a charging box and the like), a fixed terminal (such as an intelligent fan, a power supply, an intelligent water purifier, a power supply and the like) and the like, and the specific contents are as follows:
step S10, if the NFC communication request of the electronic equipment is detected, acquiring the equipment information of the electronic equipment based on the NFC wireless communication;
in the invention, the electronic equipment and the power supply equipment do not adopt the traditional contact mode to carry out data interaction, but utilize the NFC communication module to carry out data interaction. Near Field Communication (NFC) is a data Communication technology integrated and evolved through a non-contact Radio Frequency Identification (RFID) and an interconnection technology, and realizes applications such as mobile payment, electronic ticketing, door control, mobile identity recognition, anti-counterfeiting and the like by integrating functions of an induction card reader, an induction card and point-to-point Communication on a single chip and using a mobile terminal.
NFC communication modules are arranged in the electronic equipment and the power supply equipment, and data interaction between the electronic equipment and the power supply equipment can be realized through the NFC communication modules. Therefore, the charging data interaction between the electronic equipment and the power supply equipment can also be realized in an NFC communication mode. Because the NFC communication belongs to wireless communication, the power supply equipment acquires the equipment information of the power supply equipment through the NFC wireless communication after acquiring the NFC communication request of the electronic equipment. The device information refers to device state information of the current electronic device.
Further, if the NFC communication request of the electronic device is detected, the step of acquiring the device information of the electronic device based on NFC wireless communication includes:
step A1, if the NFC communication request of the electronic equipment is detected, acquiring a current first NFC communication version, and acquiring a second NFC communication version of the electronic equipment according to the NFC communication request;
step A2, if the first NFC communication version is inconsistent with the second NFC communication version, sending second prompt information for updating the NFC communication version to the electronic equipment;
step a3, if the first NFC communication version is consistent with the second NFC communication version, acquiring device information of the electronic device based on NFC wireless communication.
If the NFC communication versions of the electronic device and the power supply device are not consistent, charging communication data between the electronic device and the power supply device are likely to be abnormal. Therefore, before acquiring the device information of the electronic device, the power supply device needs to ensure that the NFC communication versions of the electronic device and the electronic device are consistent, and the power supply device acquires the current first NFC communication version of the power supply device and analyzes the second NFC communication version of the electronic device included in the NFC communication request. The power supply equipment compares the first NFC communication version with the second NFC communication version, if the first NFC communication version and the second NFC communication version are inconsistent, prompt information for updating the NFC communication versions is prompted to the electronic equipment, the NFC communication versions of the latest versions are burnt into a chip of the electronic equipment when the chip leaves a factory, and an NFC communication version data packet on the power supply equipment can be acquired through the communication process with the power supply equipment so as to guarantee real-time updating.
Step S20, acquiring first charging request information of the equipment information, and determining first charging radio frequency power according to the first charging request information;
when the power supply equipment acquires the equipment information, analyzing and acquiring first charging request information in the equipment information, wherein the first charging request information refers to specification information of charging required by the current electronic equipment, such as required charging electric quantity, required charging voltage, charging mode, charging power and the like. The power supply equipment can adjust the charging chip thereof according to the first charging request information so as to accord with the charging specification of the current electronic equipment. For example, the first charging request message specifies that the currently required charging specification of the electronic device is that the dc voltage is 5V, the dc current is 2A, and the charging mode is the static charging mode. The power supply device will perform specification limitation on the charging chip according to the first charging request information to obtain a first charging radio frequency power meeting the specification of the power supply device, i.e., P ═ UI ═ 5 ═ 2 ═ 10W. The electronic device specifies the power required for charging the electronic device to the power supply device as the first charging radio frequency power through the first charging request information. The power supply equipment adjusts parameters of the charging chip according to the first charging request information, and determines charging power of the power supply equipment to the electronic equipment according to specification information of the electronic equipment in the first charging request information.
Further, the step of acquiring the first charging request information of the device information includes:
step B1, detecting the charging state of the device information;
step B2, judging whether the charging state has peripheral charging information;
step B3, if yes, rejecting the NFC communication request based on NFC wireless communication;
and step B4, if not, acquiring first charging request information of the equipment information.
The method comprises the steps that in the process of charging the electronic equipment, the power supply equipment acquires the charging state in the equipment information, wherein the charging state comprises the current charging equipment state information, charging voltage information and the like. In this embodiment, the electronic device may support a plurality of charging modes, such as charging in a radio frequency field with the power supply device through NFC wireless communication, performing induction charging through a charging pad of a QI protocol, and the like. If the user charges the electronic device through the external device, the current electronic device is charged through the external device to supplement the electric quantity, and the electric quantity is supplemented through the radio frequency field of the power supply device. If the electric quantity is supplemented through two kinds of charging, accidents of the electronic equipment are easily caused, so that when the charging state is detected to contain peripheral charging information, the fact that two or more charging modes are used for supplementing the electric quantity to the electronic equipment at present is proved, and at the moment, the power supply equipment needs to refuse an NFC communication request of the electronic equipment through NFC wireless communication so as to avoid accidents; if no external charging information exists in the charging state, the fact that the electronic equipment can be charged through the power supply equipment is proved, and at the moment, first charging request information in the equipment information is obtained.
Step S30, a preset charging rf field is started according to the first charging rf power, so as to charge the electronic device.
Normally, the power supply device charges the electronic device when receiving a charging request from the electronic device. In this embodiment, the power device charges the electronic device by emitting an electromagnetic induction magnetic field through the charging radio frequency field, and the electronic device induces, rectifies and filters the electromagnetic induction magnetic field in the coil, so that the electronic device obtains electric quantity. Therefore, after the power supply equipment acquires the first charging radio frequency power, the charging radio frequency field preset by the power supply equipment is started, and the magnetic field intensity, the magnetic field direction and the like of the current charging radio frequency field are determined and adjusted through the first charging radio frequency power determined by the charging chip. Therefore, the power supply equipment can determine whether to charge the electronic equipment and the charging power required by the electronic equipment in the process of carrying out NFC communication with the electronic equipment, and carries out parameter adjustment on a charging radio frequency factory through the charging chip so as to achieve the charging power and charge the electronic equipment.
Further, for ease of understanding, the present invention will be explained by way of example below:
referring to fig. 3, the electronic device shown in fig. 3 is a TWS headset (Listener), the power supply device is a charging box (Poller), and two chips are disposed in the charging box: the Application Processor and the NFC Poller, the Application Processor controls the NFC to wirelessly charge and receives data sent by an NTAG chip in the TWS earphone by utilizing the NFC Poller, and a charging power supply in the charging box can be from a battery and a USB. The TWS earphone is provided with NTAG, MCU and CHARGER 3 chips, wherein the NTAG chip is used for carrying out protocol interaction of wireless charging with the charging box and transmitting interaction information to the MCU chip; the MCU chip is used for processing all information control instructions of the TWS earphone, judging the information such as the charging power of the next step and the like according to the state information of the CHARGER chip, and transmitting the control information to the charging box by using the NTAG chip. The CHARGER chip stores the state information of the current TWS earphone battery power.
Specifically, the TWS headset controls the NTAG chip to transmit the NFC communication request to the charging box through the MCU chip, and the charging box receives the NFC communication request through the NFC poler chip to obtain the device information in the NFC communication request. The device information includes first charging request information, for example, specification information of charging required by the TWS headset, and according to the first charging request information, the charging box can adjust its charging parameters under the control of the Application Processor to adapt to the specification information of charging required by the TWS headset, so as to achieve a first charging radio frequency power required by the TWS headset. For example, the first charging request information indicates that the TWS headset needs a static charging mode, i.e., a high-power charging mode requiring a large voltage and a large current, at this time, the charging box adjusts the charging parameters of the radio frequency field in the current charging box according to the charging requirement of the high-power charging mode, so that the radio frequency field is adjusted to a high-power charging output mode, so that the TWS headset can realize high-power charging.
Further, the step of starting a preset charging radio frequency field according to the first charging radio frequency power to charge the electronic device includes:
step C1, acquiring the current available charging radio frequency power;
step C2, if the chargeable radio frequency power is smaller than the first chargeable radio frequency power, sending first prompt information with insufficient power to the electronic equipment based on NFC wireless communication;
step C3, if the chargeable rf power is greater than or equal to the first charging rf power, starting a preset charging rf field according to the first charging rf power, so as to charge the electronic device.
The chargeable radio frequency power refers to charging power which can be provided for the electronic equipment by the power supply equipment under the condition of ensuring normal operation of the equipment. In this embodiment, the standard for ensuring the normal operation of the power supply device is that after the power supply device provides the electric energy power meeting the requirement for the electronic device, the power supply device can still perform its own device function normally within a preset time, for example, even after the power supply device provides the electronic device with 10W power electric quantity meeting the specification of an earphone, the power supply device can still keep working normally within 15 minutes. Then the 10W power capacity is the available rechargeable rf power of the current power supply device.
In a practical situation, the power supply device may not be able to provide sufficient charging power for the electronic device, for example, the first charging request information of the electronic device indicates that the first charging rf power is 15W, and the maximum power that can be provided by the charging parameter adjusted by the current power supply device according to the power condition is only 5W. That is to say, the chargeable rf power is smaller than the first chargeable rf power, the current power supply device cannot provide sufficient output charging power for the electronic device, and even if the power supply device charges the electronic device, the power supply device cannot provide sufficient electric quantity, and meanwhile, the power supply device may not be normally used due to insufficient electric quantity of the device itself. Therefore, the first charging radio frequency power obtained based on the NFC wireless communication is compared with the available charging radio frequency power of the power supply equipment, and charging control is carried out according to the comparison result.
When the power supply equipment detects that the chargeable radio frequency power is smaller than the first chargeable radio frequency power, first prompt information with insufficient power is sent to the electronic equipment based on NFC wireless communication, so that the electronic equipment can adjust the power consumption of the earphone according to the first prompt information or prompt a user to supplement electric quantity in a manual charging mode. The first prompt message can also include a forced charging trigger button, that is, the current electronic device needs to answer a certain message urgently, and has urgency timeliness, so that the forced charging trigger button on the first prompt message can be triggered to generate a forced charging instruction, and the forced charging instruction is transmitted to the power supply device based on the NFC wireless communication technology, so that the power supply device is forced to start a charging radio frequency field to charge the electronic device.
Further, if the available charging radio frequency power is greater than or equal to the first charging radio frequency power, it is proved that the current power supply device can provide sufficient charging power for the electronic device, and meanwhile, the normal operation of the power supply device is not affected. For example, the current power supply device determines that the first charging radio frequency power is 10W according to the first charging request, the available charging radio frequency power of the current power supply device is 11W, and the available charging radio frequency power is greater than the first charging radio frequency power, at this time, the power supply device starts a preset charging radio frequency field according to the first charging radio frequency power to charge the electronic device.
In the invention, if an NFC communication request of electronic equipment is detected, equipment information of the electronic equipment is acquired based on NFC wireless communication; acquiring first charging request information of the equipment information, and determining first charging radio frequency power according to the first charging request information; and starting a preset charging radio frequency field according to the first charging radio frequency power so as to charge the electronic equipment. Through the scheme, the traditional contact communication mode is converted into the NFC communication control mode, so that data communication can be carried out between the electronic equipment and the power supply equipment through NFC, the phenomenon that data communication is abnormal due to contact metal aging or contact abrasion in the traditional contact communication is avoided, the data communication efficiency between the electronic equipment and the power supply equipment is improved, the normal interaction of charging data between the electronic equipment and the power supply equipment is ensured, the power supply equipment is ensured to adjust the charging mode according to the charging data of the electronic equipment in real time, the charging efficiency is improved, and the normal use of the electronic equipment is ensured.
Further, based on the first embodiment, a second embodiment of the NFC communication control method according to the present invention is provided, where in this embodiment, the step of starting a preset charging radio frequency field according to the first charging radio frequency power to charge the electronic device further includes:
step a, acquiring second charging request information of the electronic equipment based on NFC wireless communication every other first preset time;
b, determining second charging radio frequency power according to the second charging request information;
and c, if the second charging radio frequency power is not consistent with the first charging radio frequency power, performing power adjustment on the charging radio frequency field according to the second charging radio frequency power.
In the process of charging the electronic device by the power supply device, the electric quantity in the electronic device continuously increases along with the increase of the charging time. If the amount of power in the electronic device is large, the charging power of the electronic device needs to be reduced to avoid damage to the battery in the electronic device or the battery life being affected by temperature increase due to too fast charging. If the electric quantity in the electronic device is small and the current battery is adapted to the charging state, the charging power of the electronic device needs to be increased to accelerate the charging efficiency.
Because the power supply equipment and the electronic equipment are in NFC wireless communication, real-time data interaction exists between the power supply equipment and the electronic equipment, and corresponding charging interaction data are mutually transmitted in the charging process. When the electronic device detects that the electric quantity of the earphone is large, for example, 80% of the required electric quantity is reached, in order to ensure continuous normal operation of a battery of the electronic device, the electronic device reduces the required charging power, and small-power charging is performed in a trickle charging mode. When the TWS detects that the electric quantity of the earphone is small and the battery adapts to the current charging state, the electronic equipment can improve the required charging power and carry out high-power charging in a quick charging mode. It is to be understood that these power adjustment data will be written in the second charge request information.
In this embodiment, the power supply device acquires second charging request information of the electronic device through NFC wireless communication every preset time period, and determines second charging radio frequency power in the second request information, where the determination process is consistent with the process of the first charging radio frequency power. After the second charging radio frequency power is obtained, the power supply equipment compares the second charging radio frequency power with the first charging radio frequency power. If the second charging rf power is not consistent with the first charging rf power, the power supply device needs to perform power adjustment on the charging rf field according to the second charging rf power, for example, adjusting the magnetic field strength, the magnetic field direction, and the like.
The power supply equipment acquires the NFC wireless communication charging request of the electronic equipment every first preset time through NFC wireless communication interaction with the electronic equipment, so that the charging radio frequency field power of the power supply equipment is adjusted, and the charging power output to the electronic equipment is adjusted.
Further, the step of starting a preset charging rf field according to the first charging rf power for charging the electronic device further includes:
step d, acquiring a power change value sent by the electronic equipment based on NFC wireless communication in real time;
and e, if the power change value is detected to be larger than the first warning value within a second preset time period, stopping the charging radio frequency field and outputting an alarm indication sound.
In the charging process, the power supply device performs detection to acquire a power change value sent by the electronic device based on NFC wireless communication, wherein the power change value refers to the change amplitude of actual charging power of the electronic device in adjacent unit time in the charging process. Assuming that the second preset time period is 5 seconds, if the actual charging power of the electronic device in the 1 st second is 9W, the actual charging power in the 2 nd second is 10W, the actual charging power in the 3 rd second is 5W, the actual charging power in the 4 th second is 11W, and the actual charging power in the 5 th second is 6W. Then the power change value of the electronic device is 1W, 5W, 6W, 5W in 5 seconds. This proves that there is a certain variation range in the charging power in the process of acquiring the charging electric quantity by the electronic device, and if the variation range is too large, the charging process is proved to be unstable. In this case, charging is usually abnormal, which is likely to cause a safety hazard. Therefore, the variation amplitude of the detected power variation value within the second preset time length is required. In this embodiment, the first warning value is set, and if the power variation value is greater than the first warning value, it is proved that the current charging is abnormal, and the power supply device needs to stop charging the electronic device, so as to avoid an accident. For example, the first warning value is 3W, and if the power variation value is greater than the first warning value (3W) within the second preset time period (5 seconds), the power supply device will stop the function of charging the rf field, so as to disconnect the charging connection between the power supply device and the electronic device, and send out a warning indication tone to prompt the user.
The phenomenon that the power change value is larger than the first warning value is caused to be that an object influencing magnetic field induction exists between the electronic equipment and the power supply equipment if the metal block exists; or short circuit abnormality may occur in the charging chips in the power supply device and the electronic device, which may cause an excessive power variation value in the charging process and affect normal charging.
Further, based on the first embodiment, a third embodiment of the NFC communication control method according to the present invention is provided, where in this embodiment, the NFC communication control method includes:
step f, acquiring a current first real-time temperature, and acquiring a second real-time temperature of the electronic equipment based on NFC wireless communication;
and g, if the first real-time temperature or the second real-time temperature is detected to be greater than a second warning value, closing the charging radio frequency field to stop charging the electronic equipment.
In this embodiment, the power supply device or the electronic device may not realize a normal charging process because the charging chip is abnormal. Such as short circuit, chip burning, etc., which may cause temperature rise of the power supply device and the electronic device, and thus real-time temperature detection of the power supply device and the electronic device is required. In this embodiment, the power supply device obtains a first real-time temperature of the device itself in real time, and obtains a second real-time temperature of the electronic device in real time through NFC wireless communication.
And if the first real-time temperature or the second real-time temperature is greater than the second warning value, the current real-time charging temperature of the power supply equipment or the electronic equipment is proved to be abnormal and in a dangerous state, so that the danger of explosion of the current electronic equipment and a circuit of the power supply equipment due to overhigh temperature is caused, and at the moment, the power supply equipment directly stops charging the electronic equipment by closing the charging radio frequency field. It can be understood that the NFC wireless communication can carry out data interaction on the real-time temperatures of the NFC wireless communication and the NFC wireless communication, and the situation that the response of the traditional information communication method is not timely is avoided.
