首先,对本申请中的部分用语进行解释说明,以便于本领域技术人员理解。
(1)无线供电技术,或者说磁感应式无线充电(wireless power transfer,WPT)技术,是通过供电设备内发射线圈产生的交流磁场与电子设备内接收线圈耦合进行能量传输的技术。
(2)NFC技术,是通过读卡器(proximity coupling device,PCD)内发射线圈产生的交流磁场与邻近集成电路卡(proximity integrated circuit card,PICC)内接收线圈耦合进行数据传输的技术。
为了便于理解本申请实施例,下面将进一步分析并提出本申请所具体要解决的技术问题。如上所述,目前较多的供电设备都集成了无线供电技术和NFC技术。并且,为防止无线供电磁场损坏附近的PICC,供电设备往往需要进行PICC检测。示例性的,供电设备检测到附近存在PICC,便立即关闭无线供电,以保护PICC不被无线供电磁场损坏。
图1是本申请实施例提供的一种应用场景示意图。如图1所示,该应用场景中可以包括供电设备10、电子设备20以及设备30。其中,供电设备10具备无线供电功能和近场通信功能。供电设备10可以向电子设备20进行无线供电,并且可以通过发射NFC信号与设备30进行数据通信。
电子设备20具备无线充电功能。示例性的,电子设备20内安装有电池。示例性的,电子设备20可以为智能手机、平板电脑(tablet computer),膝上型电脑(laptop computer),智能手表、智能手环、智能头盔、智能眼镜、蓝牙耳机等可穿戴设备,还可以是电动汽车、无人机和扫地机器人,等等。电子设备20中的电池可以是铅酸电池、镍镉电池、镍铁电池、镍氢电池、锂离子电池等中的任意一种。示例性的,电子设备20内未安装电池。示例性的,电子设备20可以为台式电脑、座机、射频识别(radio frequency identification,RFID)卡,等等。
设备30包括邻近集成电路卡,设备30属于PICC设备。示例性的,设备30可以是学生证、饭卡、公交卡、银行卡、身份证等包括PICC的设备。
如图1所示,供电设备10向电子设备20进行无线供电,设备30进入供电设备10的检测区域。需要说明的是,现有的具备NFC功能的电子设备,其内部通常具备PICC保护功能。因此供电设备10对电子设备20进行无线供电,不会损坏电子设备20的NFC功能。如图1所示,供电设备10的检测区域大于无线供电区域。任何设备进入供电设备10的检测区域时,供电设备10可以及时关闭无线供电,防止无线供电磁场损伤PICC设备。
供电设备10发现设备30进入其检测区域,供电设备10停止向电子设备20进行无线供电。相应的,电子设备20失去供电。供电设备10停止向电子设备20进行无线供电后,供电设备10开始向设备30发射载波频率信号。
图2是一种PICC检测过程中的时域波形示意图。首先,供电设备10向设备30发射载波频率为f
NFC的启动信号。随后,供电设备10向设备30发射载波频率为f
NFC的请求(request,REQ)信号。示例性的,启动信号用于为设备30供电,启动信号至少持续5.1毫秒,使得设备30存储有足够的电量与供电设备10通讯。请求信号一般持续0.5毫秒。f
NFC为13.56MHz。最后,供电设备10接收设备30发送的回复请求(answer to request,ATQ)信号,供电设备10确认该设备30属于PICC设备,至此,供电设备10结束PICC检测。后续供电设备10与设备30之间可以传输数据。
如上所述,供电设备10从发现设备30进入其检测区域后,将停止对电子设备20进行无线供电。使得原本正在接收供电的电子设备20失去供电或者说断充,从而严重影响无线供电效率和用户的使用体验。
需要说明的是,为了防止无线供电磁场对请求信号和回复请求信号的干扰,保证PICC检测的准确性,供电设备10在发送请求信号和等待回复请求信号期间需要停止向电子设备20进行无线供电。如图2所示,请求信号只持续0.5毫秒,这期间停止向电子设备20进行无线充电对无线供电效率的影响可以忽略不计。然而,启动信号的持续时间远大于请求信号的持续时间。供电设备10长时间停止向电子设备20进行无线充电将影响无线供电效率,降低了用户的使用体验。
为了解决上述问题,本申请实施例提供了一种供电设备,可以降低PICC设备对无线供电效率的影响,提高用户的使用体验。
图3是本申请实施例提供的一种供电设备的结构示意图。本申请实施例的技术方案可以在图3举例所示的结构或者类似结构中具体实施。供电设备10可以为上述图1所示的供电设备10。如图3所示,供电设备10可以包括无线供电模块101、供电线圈14和检测模块102。无线供电模块101与供电线圈14连接。
其中,无线供电模块101用于向供电线圈14提供供电信号。供电线圈14用于接收无线供电模块101提供的供电信号,并利用该供电信号产生相应的无线供电磁场,从而为电子设备20供电。在一种实施方式中,无线供电模块101可以向供电线圈14提供不同功率的供电信号,以使得供电线圈14产生不同强度的无线供电磁场。
检测模块102用于检测供电设备10的检测区域内是否存在目标设备并检测该目标设备是否属于PICC设备,并输出相应的检测信息。其中,目标设备为除供电设备10和正在接收供电的电子设备20之外的设备。在本申请实施例中,目标设备可以属于PICC设备或不属于PICC设备。示例性的,该目标设备可以为图1中的设备30。
在一种实施例中,响应于供电设备10的检测区域存在目标设备,检测模块102输出检测信息指示供电设备10的检测区域存在目标设备。
在一种实施例中,响应于供电设备10的检测区域不存在目标设备,检测模块102输出检 测信息指示供电设备10的检测区域不存在目标设备。
在一种实施例中,响应于检测区域内的目标设备属于PICC设备,检测模块102输出检测信息指示目标设备属于PICC设备。
在一种实施例中,响应于检测区域内的目标设备不属于PICC设备,检测模块102输出检测信息指示目标设备不属于PICC设备。
在本申请实施例中,供电设备10的运行模式可以包括供电模式、PICC检测模式和PICC保护模式。在一种实施方式中,供电设备10分别运行于供电模式、PICC检测模式和PICC保护模式时,无线供电模块101可以分别向供电线圈14提供不同功率的供电信号。示例性的,供电设备10分别运行于供电模式、PICC检测模式和PICC保护模式时,无线供电模块101可以向供电线圈14提供功率依次递减的供电信号。需要说明的是,如上图2所述,供电设备10在发送启动信号期间与设备30之间无数据传输,因此无线供电磁场对启动信号的影响可以忽略不计,甚至可以直接用无线供电磁场代替启动信号向设备30供电。如此,本申请实施例提供的供电设备10运行于PICC检测模式时,供电设备10的无线供电模块101可以依旧向供电线圈14提供供电信号,从而产生无线供电磁场向电子设备20和设备30供电。
在本申请实施例中,供电设备10可以基于检测模块102输出的检测信息,实现不同运行模式的切换。在一种实施方式中,响应于检测模块102输出的检测信息,供电设备10可以运行于供电模式、PICC检测模式或者PICC保护模式。
在一种实施方式中,供电设备10运行于供电模式,响应于检测模块102输出的检测信息,供电设备10的运行模式可以从供电模式切换至所述PICC检测模式或所述PICC保护模式。
在一种实施方式中,供电设备10运行于供电模式,响应于检测模块102输出的检测信息,供电设备10的运行模式可以从供电模式切换至PICC检测模式,或者维持供电模式。在一种实施方式中,供电设备10运行于PICC检测模式,响应于检测模块102输出的检测信息,供电设备10的运行模式可以从PICC检测模式切换至PICC保护模式或供电模式。
在一种实施方式中,检测模块102输出的检测信息可以用于指示供电设备10的检测区域是否存在除供电设备10和电子设备20外的目标设备,响应于检测模块102输出的检测信息,供电设备10可以运行于供电模式或者PICC检测模式。
在一种实施例中,响应于供电设备10的检测区域存在目标设备,检测模块102输出检测信息指示供电设备10运行于PICC检测模式。
在一种实施例中,响应于供电设备10的检测区域不存在目标设备,检测模块102输出检测信息指示供电设备10运行于供电模式。
示例性的,检测模块102检测到供电设备10的检测区域内存在该目标设备,响应于检测模块102输出的检测信息,供电设备10运行于PICC检测模式。示例性的,检测模块102检测到供电设备10的检测区域内不存在该目标设备,响应于检测模块102输出的检测信息,供电设备10运行于供电模式。
在一种实施方式中,检测模块102输出的检测信息还可以用于指示供电设备10的检测区域内是否存在PICC设备,即指示进入检测区域的该目标设备是否属于PICC设备,响应于检测模块102输出的检测信息,供电设备10可以运行于PICC保护模式、供电模式或者PICC检测模式。
在一种实施例中,响应于检测区域内的目标设备属于PICC设备,检测模块102输出的检测信息指示供电设备10运行于PICC保护模式。
在一种实施例中,响应于检测区域内的目标设备不属于PICC设备,检测模块102输出 的检测信息指示供电设备10运行于供电模式。
示例性的,检测模块102检测到该目标设备属于PICC设备,响应于检测模块102输出的检测信息,供电设备10运行于PICC保护模式。示例性的,检测模块102检测到该目标设备不属于PICC设备,响应于检测模块102输出的检测信息,供电设备10运行于供电模式。示例性的,检测模块102未检测出该目标设备是否属于PICC设备,响应于检测模块102输出的检测信息,供电设备10可以维持PICC检测模式。
下面结合图1和图3,对本申请实施例中的供电设备10进行说明。其中,供电设备10的运行模式包括供电模式、PICC检测模式和PICC保护模式。
供电设备10运行于供电模式,此时供电设备10的无线供电模块101提供供电信号至供电线圈14,使得供电线圈14产生无线供电磁场向电子设备20供电。示例性的,供电设备10运行于供电模式,无线供电模块101可以提供第一功率的供电信号至供电线圈14。
如图1所示,设备30进入供电设备10的检测区域。供电设备10的检测模块102检测到设备30进入检测区域后,供电设备10切换至PICC检测模式。供电设备10运行于PICC检测模式时,无线供电模块101提供至供电线圈14的供电信号的功率可以不变或者适当降低,使得供电线圈14持续产生无线供电磁场向电子设备20和设备30供电。示例性的,供电设备10运行于PICC检测模式,无线供电模块101可以提供第二功率的供电信号至供电线圈14,上述第一功率可以大于第二功率。
供电设备10运行于PICC检测模式时,检测模块102可以检测该设备30是否属于PICC设备,并输出相应的检测信息。示例性的,图4是本申请实施例提供的一种PICC检测过程中的时域波形示意图。如图4所示,供电设备10的无线供电模块101可以提供第二功率的供电信号至供电线圈14,使得供电线圈14产生无线供电磁场向电子设备20和设备30供电。如图4所示,该供电信号的载波频率可以为f
WPT。然后,供电设备10的无线供电模块101关闭,检测模块102可以通过发射一次或者多次请求信号来检测该设备30是否属于PICC设备,并输出相应的检测信息。
若检测模块102输出的检测信息指示该设备30确实属于PICC设备,供电设备10切换至PICC保护模式。供电设备10运行于PICC保护模式时,无线供电模块101可以提供极小功率的供电信号至供电线圈14,甚至,供电设备10可以直接关闭无线供电模块101,直至PICC离开检测区域,从而有效地防止PICC受损,延长PICC设备的使用寿命,保证用户的使用体验以及财产安全。示例性的,供电设备10运行于PICC保护模式时,无线供电模块101可以提供第三功率的供电信号至供电线圈14,上述第二功率可以大于第三功率。示例性的,第三功率可以为0,相当于直接关闭无线供电模块101。相应的,若检测模块102输出的检测信息指示该设备30不属于PICC设备,则供电设备10可以切换回供电模式。若检测模块102输出的检测信息指示无法确定该设备30是否属于PICC设备,则供电设备10可以维持PICC检测模式。
如上所述,无线供电模块101在供电模式下提供的供电信号的功率可以较大,以实现对电子设备20的高效供电。无线供电模块101在PICC检测模式下提供的供电信号的功率可以等于或者小于供电模式下提供的供电信号的功率,以保证对电子设备20的持续供电并尽可能的防止损坏可能存在的PICC设备。无线供电模块101在PICC保护模式下提供的供电信号的功率可以极小甚至为0,以防止损坏PICC设备。
示例性的,电子设备20为图1所示的智能手机,或者蓝牙耳机、平板电脑和台式电脑等,供电场景一般为室内场景,供电设备10一般可以安装于客厅、卧室、教室、商场、图书馆、 食堂、银行、手术室或者是病房内。示例性的,供电场景为图书馆,设备30可以为学生证或者图书借记卡一类的PICC设备。示例性的,供电场景为食堂,设备30可以为饭卡一类的PICC设备。示例性的,供电场景为医院,设备30可以为医保卡或者身份证一类的PICC设备。示例性的,供电场景为银行,设备30可以为银行卡或者身份证一类的PICC设备,等等,此处不再赘述。
示例性的,电子设备20为电动汽车,供电场景一般可以是私家车库或者是公共停车场等。示例性的,供电场景为私家车库或者是地下的公共停车场,设备30可以为车辆开锁卡或者公交卡一类的PICC设备。
综上,本申请实施例提供的供电设备10包括多种运行模式,并且在不同的运行模式下供电设备10可以提供不同功率的供电信号。如此,供电设备10在PICC检测期间也仍然可以持续给当前的电子设备20进行无线供电,避免了电子设备20失去供电或者断充的情况。如此,本申请实施例可以在保证PICC检测效率以防止PICC设备不被损坏的同时,保证无线供电效率,极大程度上满足了用户的使用需求。
