Description

通信方法及装置、电力发送设备、电力接收设备 技术领域
本公开涉及通信技术领域，尤其涉及一种通信方法及装置、电力发送设备、电力接收设备和计算机可读存储介质。
背景技术
目前，无线充电联盟(wireless power consortium，简称WPC)标准中采用的是带内通信的方式，也就是基于124k左右的频段进行必要的握手通信，因为握手信息通信量很少，因此带内通信可以满足需求。但是随着后续的演进发展，带内通信的速率太低，无法满足新的应用需求，因此，带外通信需要被引入。
目前比较成熟的带外通信是近场通信(near field communication，简称NFC)和低功耗蓝牙(Bluetooth Low Energy，简称BLE)。但是，对于大多数设备而言，不可能同时引入NFC和BLE，如果只引入一种通信方式，而充电盘与另一种通信方式相对应，则会造成不兼容，无法进行通信。因此，在电力发送方(PTX)设备和电力接收方(PRX)设备一对一的情况下，通常以带内通信为基础，协调带外通信可以被考虑。但是，因为PTX设备(充电盘)可以一对多的充电，因此当一个PRX设备已经工作在充电盘上时，后进入的设备无法和充电盘通过带内通信的方式沟通选择NFC还是BLE作为扩展通信方式使用。因此，需要在带内通信中增加一个机制来支持一对多充电时，非同时加入充电的场景。
在一对多的充电场景下，假设PRX1是先接入PTX的一个充电设备，PRX2是后接入PTX的另一个充电设备，如果PRX1支持蓝牙，PRX2不支持蓝牙但支持NFC，那么需要带内通信让PRX2和PTX都知道彼此的情况，但此时PRX1和PTX都在进行带外通信，导致PRX2和PTX之间通信受阻，因此需要提供一种让PRX2和PTX可以进行通信的方案。如果PRX2只支持带内通信，那么如果PTX和PRX1进行蓝牙的同时，可以和PRX2进行带内通信，并且此时PTX主要是为两个PRX充电，但是和PRX2的带内通信将会影响系统的充电效率。
由此可见，目前没有考虑PTX和PRX在一对多的场景下，如何在基本不影响充电效率的前提下让PRX2和PTX进行通信。

图1是本申请一示例性实施例示出的一种通信方法的流程图，该实施例从支持多线圈的电力发送方(PTX)侧进行描述，如图1所示，该通信方法包括：
在步骤S101中，在检测到自己的负载发生变化后发送广播信号，该广播信号携带PTX支持的通信方式和当前负载状态。
其中，PTX在检测到自己的负载发生变化后，例如，在检测到第一PRX加入后，可以在固定位置周期性地发送广播信号，该广播信号可携带PTX支持的通信方式和当前负载状态，如表1所示。
表1广播信号的内容
广播信号的内容 所使用的比特数
支持的通信方式 2比特
负载状态 1比特
在步骤S102中，与第一电力接收方(PRX)进行握手通信后，为第一PRX充电。
在步骤S103中，接收第一PRX根据广播信号上报的通信状态。
第一PRX接收广播信号后，可以根据该广播信号确认PTX是否存在其他负载，并据此向PTX上报通信状态。其中，该通信状态可以包括低速率通信状态。
在步骤S104中，根据该通信状态与第一PRX进行通信。
可选地，该方法还可以包括：与PRX约定低速率带内通信模式。例如，与第一PRX约定低速率带内通信模式。该低速率带内通信模式与低速率通信状态相对应。
当接收到的通信状态为低速率通信状态时，可以根据低速率通信状态采用低速率带内通信模式与第一PRX进行低速率带内通信。
上述实施例，通过在检测到自己的负载发生变化后发送广播信号，接收第一PRX根据广播信号上报的通信状态，并根据该通信状态与第一PRX进行通信，从而实现在基本不影响充电效率的前提下让PRX和PTX进行通信。
图2是本申请一示例性实施例示出的另一种通信方法的流程图，如图2所示，在步骤S101之前，该通信方法还可以包括：
在步骤S100中，为第二PRX充电。
由于PTX可以支持多线圈，因此可以同时为多个PRX充电，例如同时为第一PRX和第二PRX充电。
需要说明的是，第一PRX和第二PRX是为了区分不同的PRX而对PRX进行的命名，第一PRX和第二PRX是相对的，并不对PRX的标识进行限定。
可选地，在上述步骤S104之后，该方法还可以包括：
在步骤S105中，若检测到第二PRX被移除，则重新发送广播信号。
若PTX检测到第二PRX被移除，即检测到自己的负载又发生变化，则重新发送广播信号。
在步骤S106中，接收第一PRX根据当前广播信号发送的通信请求，该通信请求用于请求与PTX恢复到带内增强通信状态。
第一PRX根据当前广播信号可以获知第二PRX已被移除，则可以请求与PTX恢复到带内增强通信状态，以提高通信效率。
在步骤S107中，根据该通信请求与第一PRX进行带内增强通信。
上述实施例，若检测到第二PRX被移除，则重新发送广播信号，接收第一PRX根据当前广播信号发送的通信请求，并根据该通信请求与第一PRX进行带内增强通信，从而在不影响充电效率的同时，提高通信效率。
图3是本申请一示例性实施例示出的另一种通信方法的流程图，如图3所示，在上述步骤S107之后，该通信方法还可以包括：
在步骤S108中，若检测到支持带外通信的第三PRX接入，则与第三PRX进行带外通信。
由于带外通信不影响充电效率，所以在检测到支持带外通信的第三PRX接入时，可以与第三PRX进行带外通信。
在步骤S109中，向第一PRX发送指示信息，该指示信息用于指示将带内通信速率降低为预设速率。
其中，预设速率与低速率带内通信模式对应的速率可以相同，也可以不同。
在步骤S110中，采用预设速率与第一PRX进行低速率带内通信。
为了减少因第三PRX的加入而影响第一PRX的充电效率，该实施例可以向第一PRX发送指示信息，并采用预设速率与第一PRX进行低速率带内通信，从而减少因通信对充电效率的影响。
上述实施例，若检测到支持带外通信的第三PRX接入，则与第三PRX进行带外通信，向第一PRX发送指示信息，该指示信息用于指示将带内通信速率降低为预设速率，并采用预设速率与第一PRX进行低速率带内通信，从而减少因通信对充电效率的影响。
图4是本申请一示例性实施例示出的又一种通信方法的流程图，该实施例从PRX侧进行描述，如图4所示，该方法包括：
在步骤S401中，接收PTX发送的广播信号。
其中，PRX可以在当前周期的固定位置检测广播信号，若检测到广播信号，则接收该广播信号。
在步骤S402中，与PTX进行握手通信后，从PTX接收电能。
在步骤S403中，若根据该广播信号确认PTX存在其他负载，则向PTX上报通信状态。
例如，若PRX2根据广播广播信号确认PTX存在其他负载PRX1，则可以向PTX上报通信状态，该通信状态可以包括低速率通信状态。
在步骤S404中，根据该通信状态与PTX进行通信。
可选地，该方法还可以包括：与PTX约定低速率带内通信模式。该低速率带内通信模式与低速率通信状态相对应。
当该通信状态为低速率通信状态时，可以根据低速率通信状态采用低速率带内通信模式与PTX进行低速率带内通信。
上述实施例，通过接收PTX发送的广播信号，并在根据广播信号确认PTX存在其他负载时，向PTX上报通信状态，并根据通信状态与PTX进行通信，从而实现在基本不影响充电效率的前提下与PTX进行通信。
图5是本申请一示例性实施例示出的另一种通信方法的流程图，如图5所示，在步骤S404之后，该方法还可以包括：
在步骤S405中，接收PTX更新发送的广播信号。
若PTX检测到自己的负载又发生变化，则重新发送广播信号。
在步骤S406中，根据当前广播信号向PTX发送通信请求，该通信请求用于请求与PTX恢复到带内增强通信状态。
若根据当前广播信号确认PTX移除了其他负载，可以请求与PTX恢复到带内增强通信状态。
在步骤S407中，与PTX进行带内增强通信。
上述实施例，通过接收PTX更新发送的广播信号，根据当前广播信号向PTX发送通信请求，并与PTX进行带内增强通信，可以在不影响充电效率的同时，提高通信效率。
图6是本申请一示例性实施例示出的另一种通信方法的流程图，如图6所示，在步骤S407之后，该方法还可以包括：
在步骤S408中，接收PTX发送的指示信息，该指示信息用于指示将带内通信速率降低为预设速率。
