Description

近場通訊與無線充電共用感應模組的選擇方法及其選擇電路Near field communication and wireless charging sharing sensing module selection method and selection circuit thereof

本發明係為一種近場通訊與無線充電共用感應模組的選擇方法及其選擇電路，特別是關於一種使用在可攜式設備上，整合無線充電(Wireless Charging,WLC)感應模組與近場通訊(Near Field Communication,NFC)感應模組為一體的感應模組選擇方法及選擇電路。The invention relates to a method for selecting a near field communication and a wireless charging sharing sensing module and a selection circuit thereof, in particular to a method for integrating a wireless charging (WLC) sensing module and a near field in a portable device. The Near Field Communication (NFC) sensing module is an integrated sensing module selection method and selection circuit.

新型式的無線充電(WLC)技術使得可攜式設備不需要使用電力線，而可利用電磁感應的方式直接傳輸電力給該些可攜式設備對電池充電。如圖一所示，係為一無線充電傳輸的架構示意，包括有一電力傳送模組10及一電力接收模組20，該電力傳送感應模組10具有一傳送端線圈11、一傳送端鐵心板12，而該電力接收感應模組20亦同樣具有一接收端線圈21、一接收端鐵心板22。當該電力接收模組20靠近該電力傳送模組10時，電流流經該電力接收模組10的傳送端線圈11產生磁場，使得該電力接收感應模組20的接收端線圈21感應該磁場產生電流。The new type of wireless charging (WLC) technology enables portable devices to use no power lines, but can directly transmit power to the portable devices to charge the batteries by means of electromagnetic induction. As shown in FIG. 1 , it is a schematic diagram of a wireless charging transmission, including a power transmission module 10 and a power receiving module 20 . The power transmission sensing module 10 has a transmitting end coil 11 and a transmitting end core plate. 12, the power receiving sensing module 20 also has a receiving end coil 21 and a receiving end core plate 22. When the power receiving module 20 is close to the power transmitting module 10, a current flows through the transmitting end coil 11 of the power receiving module 10 to generate a magnetic field, so that the receiving end coil 21 of the power receiving sensing module 20 senses the magnetic field. Current.

另外目前在可攜式電子設備中結合近場通訊(NFC)也是相當地被受到重視，近場通訊(NFC)能夠讓可攜式設備進行非接觸式點對點通訊，提供極為便利的連接方式，可快速、簡便地進行通訊。In addition, the combination of Near Field Communication (NFC) in portable electronic devices is also receiving considerable attention. Near Field Communication (NFC) enables portable devices to perform contactless point-to-point communication, providing extremely convenient connection methods. Communicate quickly and easily.

近場通訊(NFC)技術是由非接觸式射頻識別(RFID)及互連技術的整合演變而來，在目前近場通訊(NFC)的應用領域中就有如交通捷運系統中使用的感應卡，只要將感應卡靠近捷運查票口即可快速通關，而且感應時間比一般非接觸式晶片卡更快，這對高進出量的交通站而言相當受用。Near Field Communication (NFC) technology evolved from the integration of contactless radio frequency identification (RFID) and interconnect technology. In the current field of near field communication (NFC) applications, there are proximity cards used in the MRT system. As long as the proximity card is close to the MRT ticket gate, it can be quickly cleared, and the induction time is faster than the general non-contact wafer card, which is quite useful for high-input traffic stations.

因此有業者提出將近場通訊晶片嵌入於手機等可攜式電子設備內，也因此可攜式電子設備整合無線充電(WLC)與近場通訊(NFC)的功能將是未來不可避免的趨勢。Therefore, some manufacturers have proposed to embed a near field communication chip in a portable electronic device such as a mobile phone. Therefore, the integration of wireless charging (WLC) and near field communication (NFC) functions of the portable electronic device will be an inevitable trend in the future.

然而目前近場通訊(NFC)及無線充電傳輸(WLC)這二種電路完全不同，各自獨立，必需使用各自的感應線圈模組，接收各自不同的訊號，這對可攜式電子設備越來越輕薄短小的內部空間而言，整合難度相當高。However, the two circuits of Near Field Communication (NFC) and Wireless Charge Transmission (WLC) are completely different, and they are independent. They must use their respective induction coil modules to receive different signals. This is becoming more and more portable electronic devices. In terms of light and short internal space, integration is quite difficult.

本案發明人發現近場通訊(NFC)及無線充電傳輸(WLC)二種技術都是近距離感應傳輸訊號，因此都需使用到線圈感應模組，且該二種感應模組並不會同時使用，且二種感應模組所感應的頻率亦不相同，因此設計了一種整合近場通訊(NFC)與無線充電(WLC)共用的感應模組，可接收來自近場通訊(NFC)與無線充電(WLC)的訊號，再藉由一組線路選擇電路進行訊號的自動切換選擇。The inventor of the present invention found that both the near field communication (NFC) and the wireless charging transmission (WLC) technologies are short-range inductive transmission signals, so the coil sensing modules are required, and the two sensing modules are not used at the same time. And the sensing frequency of the two sensing modules is also different, so a sensing module integrated with Near Field Communication (NFC) and Wireless Charging (WLC) is designed to receive NFC and wireless charging. The (WLC) signal is then automatically switched by a set of line selection circuits.

本發明之目的係在於提供一種近場通訊與無線充電共用感應模組的選擇方法及其選擇電路，將近場通訊(NFC)與無線充電(WLC)二種不同頻率信號的感應模組整合於一體，以縮小感應線圈在可攜式電子設備中所佔據的面積，以便達成將二種功能整合於同一可攜式電子設備的目的。The object of the present invention is to provide a method for selecting a near field communication and a wireless charging sharing sensing module and a selection circuit thereof, and integrating the sensing modules of two different frequency signals of near field communication (NFC) and wireless charging (WLC).
