Description
技术领域technical field
本发明涉及一种无线充电和NFC(Near Field Communication)领域，特别涉及一种兼容无线充电和NFC的方法及装置。The invention relates to the fields of wireless charging and NFC (Near Field Communication), in particular to a method and device compatible with wireless charging and NFC.
背景技术Background technique
目前，移动终端被运用的越来越广泛，终端的功能已经非常强大，充满丰富的娱乐性，可以听歌，可以看电视，可以上网等等。在使用移动终端的过程中，由于电池容量的局限性，人们发现电池的电量很快就使用完，经常需要对电池充电。以电磁感应为代表的无线充电技术的出现，给消费者带来了方便。通过无线充电设备可以方便给手机充电，让消费者摆脱了线的束缚。At present, mobile terminals are used more and more widely, and the functions of the terminals are very powerful, full of rich entertainment, such as listening to music, watching TV, surfing the Internet and so on. In the process of using the mobile terminal, due to the limitation of the battery capacity, people find that the power of the battery is used up soon, and the battery often needs to be charged. The emergence of wireless charging technology represented by electromagnetic induction has brought convenience to consumers. The wireless charging device can conveniently charge the mobile phone, freeing consumers from the shackles of wires.
近场通信NFC又称近距离无线通信，是一种短距离的无线通信技术，允许电子设备之间进行非接触式点对点数据传输(在十厘米内)交换数据。这个技术由免接触式射频识别(RFID)演变而来，并向下兼容RFID，最早由Philips、Nokia和Sony主推，主要用于手机等手持设备中。由于近场通讯具有天然的安全性，因此，NFC技术被认为在手机支付等领域具有很大的应用前景。目前NFC在手机支付领域使用的频率越来越高。Near field communication NFC, also known as short-range wireless communication, is a short-range wireless communication technology that allows non-contact point-to-point data transmission (within ten centimeters) to exchange data between electronic devices. This technology evolved from contactless radio frequency identification (RFID) and is backward compatible with RFID. It was first promoted by Philips, Nokia and Sony, and is mainly used in handheld devices such as mobile phones. Due to the natural security of near-field communication, NFC technology is considered to have great application prospects in fields such as mobile payment. At present, NFC is used more and more frequently in the field of mobile payment.
以电磁感应为代表的无线充电技术是当前主流的无线充电技术，无线充电联盟组织已经制定出了Qi标准，用来规范无线充电技术。其基本结构如图1所示，主要分为两个部分，一个是发送端，一个是接收终端，发送端和接收终端之间通过感应线圈实现电能的传替。接收终端原理框图如图2所示，接收线圈接收到电量后传递至接收电路，接收电路完成整流稳压等等功能，输出手机终端充电使用的稳定的直流电压。NFC的电路框图如图3所示，包括NFC芯片电路，匹配电路，NFC天线线圈。The wireless charging technology represented by electromagnetic induction is the current mainstream wireless charging technology. The Wireless Charging Alliance has formulated the Qi standard to regulate wireless charging technology. Its basic structure is shown in Figure 1. It is mainly divided into two parts, one is the transmitting end and the other is the receiving terminal. The transmission of electric energy is realized through the induction coil between the transmitting end and the receiving terminal. The schematic block diagram of the receiving terminal is shown in Figure 2. The receiving coil receives the power and transmits it to the receiving circuit. The receiving circuit completes functions such as rectification and voltage stabilization, and outputs a stable DC voltage for charging the mobile phone terminal. The circuit block diagram of NFC is shown in Figure 3, including NFC chip circuit, matching circuit, and NFC antenna coil.
当前的技术，同时使用无线充电和NFC时，手机终端会使用两个独立的线圈天线，一个给无线充电使用，另外一个给NFC使用。两个线圈的面积会需要很大的空间，在手机越来越精致的趋势下，空间对手机终端来讲是很宝贵的资源，而且两个线圈放置一起时候，相互之间还有干扰，影响彼此的性能。In the current technology, when wireless charging and NFC are used at the same time, the mobile phone terminal will use two independent coil antennas, one for wireless charging and the other for NFC. The area of the two coils will require a lot of space. With the trend of mobile phones becoming more and more refined, space is a very precious resource for mobile terminals, and when the two coils are placed together, there will be interference between them, affecting each other's performance.

In the initial stage, there is a communication initialization process between the wireless charging transmitter and receiver, between NFC and the card reader, but the communication content of wireless charging and NFC is different, and the determination circuit module transmits signals according to different communications Determine whether it is wireless charging or NFC function. It is also possible to determine whether to carry out wireless charging or NFC according to the frequency of the sending signal. The standard communication frequency of NFC is 13.56M, and the frequency of wireless charging is about 100K. According to the frequency difference between the two signals, the business mode can be intelligently determined.
当识别为无线充电功能时候，判定电路模块连通线圈与无线充电接收模块，线圈与NFC模块是断开状态，线圈作为无线充电的接收线圈；当识别为NFC功能时候，判定电路模块连通线圈与NFC模块，线圈与无线充电接收模块是断开状态，线圈作为NFC的天线。When it is recognized as the wireless charging function, it is determined that the circuit module is connected to the coil and the wireless charging receiving module, and the coil and the NFC module are disconnected, and the coil is used as the receiving coil of wireless charging; The module, the coil and the wireless charging receiving module are disconnected, and the coil is used as the antenna of NFC.

For example, assuming that during NFC communication, the initial identification header is 10XXXXXX, and during wireless charging, the initial identification header is 01XXXXXX, then the attribute of the signal received by the coil can be judged according to the content of the header.
其中，判定电路模块包括：用于识别天线接收何种信号的天线信号识别单元；根据天线信号识别单元的识别结果，进行切换的切换单元。Wherein, the determination circuit module includes: an antenna signal identification unit for identifying what kind of signal the antenna receives; a switching unit for switching according to the identification result of the antenna signal identification unit.
