相关申请的交叉引用
本申请基于申请号为201710677043.7、申请日为2017年08月09日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以全文引入的方式引入本申请。
技术领域
本发明实施例涉及家用电器技术领域，尤其涉及一种通信方法、装置及设备。
背景技术
无线充电指的是功率发射端将能量无线地传送给功率接收端，从而不需要通过有线连接进行充电。无线充电技术应用于家电行业，从而可以实现为家用电器中的可拆卸部件内的电子器件及电子装置进行供电，并使得家电设备的结构不受连线的限制。
以电压力锅为例，目前的电压力锅为了有效地对内胆内腔中的温度和压力进行检测，通常会在上盖设置有压力检测装置以及温度检测装置；而为了向这两个装置提供电力，通常上盖与电压力锅的煲体之间通过排线进行连接，该排线除了能够为上盖中的检测装置提供电力，还可以作为检测装置向电压力锅的控制单元传输检测数据的传输路径。若上盖能够可拆卸的装配在煲体上，那就需要取消排线，并采用无线充电技术向上盖中的检测装置进行供电。比如，电饭煲的上盖设置功率接收端，而功率发射端设置在煲体上，通过感应耦合以将电功率从功率发射端处的初级线圈传递到功率接收端处的邻近的次级线圈。此外，为了能够使上盖的检测装置将检 测数据传输到电压力锅的控制单元，可以通过无线充电进行通信。
目前对于无线充电双方之间进行通信的技术方案，通常采用的是单向通信方案，比如由功率接收端利用无线充电时的线圈载波将数据发送到功率发射端。而功率接收端与功率发射端之间进行相互通信只能利用线圈载波来实现，因此只能通过半双工的方式进行，从而会出现通信冲突的状况发生。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
实施例一
参见图1，其示出了本发明实施例提供的一种通信装置1，该装置1可以应用于一设备中，该装置1可以包括：无线充电的功率接收器10以及无线充电的功率发射器20；其中，
所述功率接收器10，被配置为按照设定的传输周期将第一待发送数据通过接收线圈载波发送至所述功率发射器20；
所述功率发射器20，被配置为接收所述第一待发送数据，并对所述第一待发送数据进行校检；以及，
所述第一待发送数据校检成功后，在设定的间隔时长后通过发射线圈载波将第二待发送数据发送至所述功率接收器10；其中，所述传输周期的时间长度T大于所述预设的间隔时长t1。
需要说明的是，由于无线充电的两端需要通过线圈载波来实现信息和数据的交互，因此，两端之间的通信属于半双工模式。图1所示的通信装置1通过设定固定的时间间隔来进行信息和数据的交互，从而避免功率接收器10以及功率发射器20之间的通信紊乱，也避免了功率接收器10与功率发射器20在无线充电时发生通信冲突，使得功率接收器10与功率发射器20能够进行有序的通信。此外，本发明实施例中，仅以家电设备作为通信装置1所在的设备示例，可以理解地，本发明实施例所描述的通信装置也可以应用于其他设备。
在一种可能的实现方式中，参见图2所示的通信装置1的具体结构，图1中虚线框所示的功率接收器10可以包括：第一主控芯片101、整流电路102、稳压电路103、第一通信解调电路104、通信调制电路105和接收线圈106；而图1所示的功率发射器20可以包括：第二主控芯片201、线圈驱动电路202、第二通信解调电路203和发射线圈204；其中，
所述第二主控芯片201分别与所述线圈驱动电路202和第二通信解调电路203相连，第二通信解调电路203与所述线圈驱动电路202相连，所 述线圈驱动电路202与所述发射线圈204相连；所述发射线圈204与所述接收线圈106通过感应耦合；所述接收线圈106分别与所述整流电路102、第一通信解调电路104以及通信调制电路105相连接；所述整流电路102还与所述稳压电路103相连；所述稳压电路103分别与其他负载以及所述第一主控芯片101相连；所述第一通信解调电路104和所述通信调制电路105均与所述第一主控芯片101相连。
基于图2所示的结构，优选地，实现图1所示的功率接收器10与功率发射器20的配置方案，具体可以包括：
所述第一主控芯片101，被配置为控制所述通信调制电路105将所述第一待发送数据进行调制，并将调制后的第一待发送数据传输至所述接收线圈106；
所述接收线圈106，被配置为将所述调制后的第一待发送数据通过接收线圈载波传输至所述发射线圈204；
所述第二通信解调电路203，被配置为将所述调制后的第一待发送数据进行解调，得到原始的第一待发送数据；
所述第二主控芯片201，被配置为对所述第一待发送数据进行校检；以及，在预设的间隔时长后将第二待发送数据进行调制，并将调制后的第二待发送数据传输至线圈驱动电路202；可以理解地，第二主控芯片201可以通过脉冲宽度调制(PWM，Pulse Width Modulation)的方式将第二待发送数据进行调制；
所述线圈驱动电路202，被配置为驱动所述发射线圈204将调制后的第二待发送数据通过发射线圈载波传输至所述接收线圈106；
所述接收线圈106，还被配置为接收到的载波分别发送至整流电路102和第一解调电路104；
所述整流电路102，被配置为将接收到的载波传输至所述稳压电路103 后，为所述其他负载提供稳定的直流电源；
所述第一通信解调电路104，用于将接收到的载波进行解调，得到原始的第二待发送数据，并将所述第二待发送数据传输至所述第一主控芯片101。
对于上述优选方案，需要说明的是，发射线圈204和接收线圈106可以相邻放置，两者之间的距离小于50毫米，从而使接收线圈106处于发射线圈204产生的电磁场场范围内，导致接收线圈106上能够产生感应电压。当接收线圈106产生感应功率后，由于为交流电压，通过整流电路102和稳压电路103后产生可供其他负载使用的稳定直流电源。
此外，考虑到数据发送的时长，当功率接收器10发送所述第一待发送数据所需的时长为t2，且功率发送器20发送所述第二待发送数据所需的时长为t3时，所述传输周期的时间长度T满足下式所示条件：
T>t1+t2+t3。
综合上述图1和图2所示的技术方案，图1和图2所示的通信装置10可以应用于一设备中，该设备包括：设备主体、可拆卸部分以及图1和图2中所述的任意的通信装置1；其中，所述通信装置1包括：无线充电的功率发射器20以及无线充电的功率接收器10，所述功率接收器10可以设置于所述可拆卸部分。所述功率发射器20可以设置于所述设备主体。
以电压力锅为例，参见图3，为非典型示例的电压力锅30的正视图，电压力锅30可以包括上盖301和煲体302；上盖301能够可拆卸的安装在煲体302上，因此，煲体302即为设备主体，上盖301为可拆卸部分。由于目前电压力锅上盖301设置有检测电压力锅内胆的内腔温度值和内腔压力值的检测装置，因此，当上盖301能够可拆卸的安装时，这些检测装置所需的电力可以通过无线充电进行提供，而煲体302内的控制单元需要接收这些检测装置从上盖301发送的检测数据，并且根据这些检测数据向上 盖302中的控制单元发送控制指令，以控制上盖301中排气阀的开启和关闭。因此根据图1或图2所示的通信装置，能够在实现向可拆卸的上盖301的检测装置提供电力的同时，完成上盖301与煲体302之间的数据交互。
实施例二
基于前述实施例相同的技术构思，参见图4，其示出了本发明实施例提供的一种通信方法，该方法可以应用于家电设备中，该家电设备可以包括无线充电的功率发射端和无线充电的功率接收端，所述方法包括：
S401：功率接收端按照设定的传输周期将第一待发送数据通过接收线圈载波发送至功率发射端；
S402：功率发射端接收第一待发送数据，并对第一待发送数据进行校检；
S403：第一待发送数据校检成功后，功率发射端在设定的间隔时长后通过发射线圈载波将第二待发送数据发送至功率接收端；
其中，所述传输周期的时间长度T大于所述预设的间隔时长t1。
需要说明的是，无线充电的两端之间需要通过线圈载波来实现信息和数据的交互，因此，两端之间的通信属于半双工模式，对于图4所示的技术方案，通过设定固定的时间间隔来进行信息和数据的交互，从而避免功率接收端以及功率发射端之间的通信紊乱；并且由于将功率接收端的传输周期的时间长度设置为大于功率发射端发送数据的间隔时长，从而使得在某一确定的时间点上，功率接收端与功率发射端之间最多仅有一端在发送数据，于是也避免了功率接收端以及功率发射端在无线充电状态下进行通信时发生通信冲突，使得功率接收端以及功率发射端能够进行有序的通信。
结合前述实施例所述的通信装置，可以得知，图4所示技术方案中的功率接收端以及功率发射端分别对应通信装置中的功率接收器和功率发射器。
作为一种可实现的实施方式，需要说明的是，当所述第一待发送数据用于表征所述设备的工作状态时，所述第二待发送数据包括所述工作状态对应的控制指令。于是，当所述第一待发送数据用于表征所述设备的工作状态时，所述功率发射端在设定的间隔时长后通过发射线圈载波将第二待发送数据发送至所述功率接收端，包括以下三个步骤：
所述功率发射端根据所述第一待发送数据获知所述设备的工作状态；
所述功率发射端根据所述设备的工作状态获取对应的控制指令；
所述功率发射端在设定的间隔时长后通过发射线圈载波将所述控制指令发送至所述功率接收端。
以电压力锅作为非典型示例，无线充电的功率发射端可以设置在电压力锅的煲体中，无线充电的功率接收端可以设置在电压力锅的上盖中。对于电压力锅来说，上盖是可拆卸的安装在煲体上，因此，当上盖设置有检测内胆的内腔温度值和内腔压力值的检测装置时，可以通过无线充电的方式来为检测装置提供电力。还需要说明的是，检测装置所得到的检测数据需要从上盖传输至煲体内的控制单元，煲体内的控制单元根据检测数据确定是否对上盖中的排气阀进行开启和关闭，因此，煲体也需要将针对检测数据向上盖发送关于排气阀的控制指令，从而使得上盖中的控制单元根据控制指令来控制排气阀的开启和关闭。因此，上盖中的检测装置所得到检测数据，比如内腔温度值和内腔压力值这些用来描述电压力锅工作状态的参数就是第一待发送数据；而煲体内的控制单元根据这些检测数据得到排气阀的控制指令，该控制指令就是第二待发送数据，上盖内的控制单元在接收到控制指令后，就能够根据控制指令的指示来控制排气阀的开启和关闭。
具体来说，仍然以电压力锅为例，电压力锅的上盖设置有针对内胆的内腔进行温度检测和压力检测的传感器，还设置有进行无线充电的功率接 收器，在本具体示例中标识为主机；电压力锅的煲体中设置有针对数据进行分析的控制单元，还因为通常电压力锅的煲体能够直接通过市电进行供电，因此，设置有进行无线充电的功率发射器，在本具体示例中标识为从机，参见图5所示的波形时序图，主机可以按照固定的传输周期T向从机发送传感器的检测数据；从机在接收到检测数据后，将检测数据进行校验，并在校验成功后，在预设的间隔时长t1后，向主机发送针对检测数据的回应数据；可以理解地，当检测数据为内腔的温度值和压力值，那么回应数据则可以是与内腔的温度值和压力值对应的控制指令，用来控制上盖中排气阀的开启和关闭。主机在接收到回应数据后，上盖根据回应数据来对排气阀进行控制。
作为一种可实现的实施方式，如果考虑到数据发送的时长，那么当所述功率接收端发送所述第一待发送数据所需的时长为t2，且所述功率发送端发送所述第二待发送数据所需的时长为t3时，所述传输周期的时间长度T满足下式所示条件：
T>t1+t2+t3。
本实施例提供了一种通信方法，通过设定固定的时间间隔来进行信息和数据的交互，从而避免功率接收端以及功率发射端之间的通信紊乱，也避免了功率接收端以及功率发射端在无线充电时发生通信冲突，使得功率接收端以及功率发射端能够进行有序的通信。
以上所述，仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。
工业实用性
本发明实施例中，通过设定固定的时间间隔来进行信息和数据的交互，从而避免功率接收端以及功率发射端之间的通信紊乱；并且由于将功率接收端的传输周期的时间长度设置为大于功率发射端发送数据的间隔时长，从而使得在某一确定的时间点上，功率接收端与功率发射端之间最多仅有一端在发送数据，于是也避免了功率接收端以及功率发射端在无线充电状态下进行通信时发生通信冲突，使得功率接收端以及功率发射端能够进行有序的通信。
