下面参考附图描述本申请实施例的电子设备间的通信控制方法、装置、电子设备以及介质。
图1为本申请实施例提供的一种电子设备间的通信控制方法的流程示意图。
本申请实施例中，电子设备可以为智能手机、平板电脑、个人数字助理、穿戴式设备等具有各种操作系统的硬件设备。
如图1所示，该电子设备间的通信控制方法包括以下步骤：
步骤101，判断第一电子设备是否与第二电子设备建立光保真LiFi连接。
其中，光保真技术(Light Fidelity，简称LiFi)，是一种利用可见光波谱(如灯泡发出的光)进行数据传输的全新无线传输技术。
相关技术中，电子设备之间采用WiFi技术建立无线通信连接成功后，为了保证无线通信连接的稳定性，即使射频信号中断一段时间也会保持连接状态，且延时较长(10s以上)。然而，电子设备之间建立LiFi连接后，当通信光发生中断或出现遮挡导致通信光未对准时，电子设备之间的通信状态就会出现异常，因此，需要立刻检测到LiFi连接的异常状态。
本申请实施例中，可以通过增加Socket心跳包机制的方法判断第一电子设备是否与第二电子设备建立LiFi连接。
在一种可能的情况下，第一电子设备向第二电子设备发送第一探测包，在发送第一探测包时启动超时定时器，第二电子设备接收到第一电子设备发送的第一探测包后，第二电子设备向第一电子设备发送应答包，第一电子设备接收到第二电子设备发送的应答包，说明第一电子设备与第二电子设备之间已经建立LiFi连接，并且LiFi连接可以使得第一电子设备与第二电子设备之间正常通信。这种情况下，第一电子设备可以删除超时定时器。
在另一种可能的情况下，第一电子设备向第二电子设备发送第一探测包，在发送第一探测包时启动超时定时器，若第一电子设备的超时定时器超过预设时长，没有接收到第二电子设备发送的应答包。这种情况下，确定第二电子设备的通信存在异常，并且第一电子设备未与第二电子设备建立LiFi连接。
在又一种可能的情况下，第一电子设备超过预设时长未向第二电子设备发送第一探测包，说明第一电子设备端的通信存在异常，这种情况下，第一电子设备未与第二电子设备建立LiFi连接。
需要说明的是，第一电子设备与第二电子设备建立的LiFi连接，能够实现第一电子设备和第二电子设备之间的双向通信。也就是说，第一电子设备能够向第二电子设备发送数据，同时，也能够接收到第二电子设备发送的数据。同样的，第二电子设备能够向第一电子设备发送数据，同时，也能够接收到第一电子设备发送的数据。
步骤102，确定第一电子设备未与第二电子设备建立LiFi连接，则控制第一电子设备进入扫描模式，其中，在扫描模式之中，控制LiFi模组以第一占空比进行开启。
其中，占空比，是指在一个脉冲循环内，通电时间相对于总时间所占的比例。例如，脉冲宽度为1μs，信号周期为4μs的脉冲序列占空比为0.25。
在一种可能的情况下，确定第一电子设备未与第二电子设备建立LiFi连接，则控制第一电子设备进入扫描模式。并且，在扫描模式之中，控制LiFi模组以第一占空比进行开启。
本申请实施例中，确定第一电子设备未与第二电子设备建立LiFi连接，仅需要考虑WiFi本身所需的连接时间，以及LiFi模组输入输出口开启和关闭的时间，在控制第一电子设备进入扫描模式后，控制LiFi模组以第一占空比进行开启。
本申请实施例中，LiFi模组，可以包括光信号发射模块和光信号接收模块。LiFi模组还可以包括三个部分，其中，第一部分为应用处理器及WiFi芯片部分，用来提供射频信号。第二部分为射频转基带信号，用于将连接到天线的2.4Ghz/5GHz射频信号通过混频器变频到基带，之后信号被分离为上行路径和下行路径。第三部分为基带电信号通过光学前端转换为光信号，在上行路径侧，信 号用于驱动光信号发射器，例如VCSEL器件；在下行路径侧，可见光由光电二极管接收，低噪声放大并转向到射频和基带接口。
步骤103，确定第一电子设备已与第二电子设备建立LiFi连接，则控制第一电子设备进入连接模式。
其中，在连接模式之中，控制LiFi模组以第二占空比进行开启并向第二电子设备发送第一心跳包，同时接收第二电子设备发送的第二心跳包。
本申请实施例中，确定第一电子设备已与第二电子设备建立LiFi连接，则控制第一电子设备进入连接模式，并控制LiFi模组由第一占空比切换至第二占空比。
在一种可能的情况下，确定第一电子设备已与第二电子设备建立LiFi连接，且第一电子设备与第二电子设备之间未发送信息时，控制第一电子设备进入连接模式。
本申请实施例中，确定第一电子设备已与第二电子设备建立LiFi连接之后，需要保证第一电子设备与第二电子设备能够双向通信，因此，需要设置双通路心跳包。其中，心跳包是指在第一电子设备与第二电子设备间定时通知对方自身状态的一个自己定义的命令字，按照一定的时间间隔发送，类似于心跳，所以叫做心跳包。
作为一种可能的实现方式，控制第一电子设备进入连接模式后，控制LiFi模组以第二占空比进行开启并向第二电子设备发送第一心跳包，同时接收第二电子设备发送的第二心跳包。
需要解释的是，上述步骤102和步骤103不是顺序执行的，可以仅执行步骤102，也可以仅执行步骤103，在此不做限制。
本申请实施例的电子设备间的通信控制方法，通过判断第一电子设备是否与第二电子设备建立光保真LiFi连接；确定第一电子设备未与第二电子设备建立LiFi连接，则控制第一电子设备进入扫描模式，其中，在扫描模式之中，控制LiFi模组以第一占空比进行开启；以及确定第一电子设备已与第二电子设备建立LiFi连接，则控制第一电子设备进入连接模式，其中，在连接模式之中，控制LiFi模组以第二占空比进行开启并向第二电子设备发送第一心跳包，同时接收第二电子设备发送的第二心跳包。由此，通过判断第一电子设备与第二电子设备之间是否建立LiFi连接，以控制LiFi模组开启时采用不同的占空比，从而降低了两电子设备的功耗。
在上述实施例的基础上，在上述步骤102中，控制LiFi模组以第一占空比进行开启时，还可以通过判断第一电子设备是否与第二电子设备建立过连接，以控制LiFi模组的第一占空比的值。下面结合图2对上述过程进行详细介绍，图2为本申请实施例提供的另一种电子设备间的通信控制方法的流程示意图。
如图2所示，上述步骤102还可以包括：
步骤201，判断第一电子设备是否已与第二电子设备建立过LiFi连接。
本申请实施例中，确定第一电子设备未与第二电子设备建立LiFi连接时，进一步判断第一电子设备是否已与第二电子设备建立过LiFi连接。
作为一种可能的实现方式，可以根据第一电子设备和第二电子设备中LiFi模组开启时长判断第 一电子设备是否已与第二电子设备建立过LiFi连接。若第一电子设备和第二电子设备中LiFi模组开启时长相同，则确定第一电子设备与第二电子设备已建立过连接。若第一电子设备和第二电子设备中LiFi模组开启时长不相同，则确定第一电子设备未与第二电子设备建立过连接。
步骤202，确定第一电子设备未与第二电子设备建立过连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第二时长。
其中，第二时长为第一时长与随机时长之和，随机时长小于或等于第一时长。
需要说明的是，若第一电子设备和第二电子设备的LiFi模组开关时长相同，例如，均为500ms，可能存在第一电子设备的处于LiFi模组开启状态，第二电子设备的LiFi模组处于关闭状态情况，这种情况下，第一电子设备和第二电子设备永远无法建立LiFi连接。
因此，为了确保第一电子设备与第二电子设备之间能够成功建立LiFi连接，可以控制LiFi模组开启的第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第二时长。其中，第二时长为第一时长与随机时长之和，随机时长小于或等于第一时长。
举例来说，LiFi模组开启的第一时长为500ms，LiFi模组关闭的第二时长可以为500ms与随机时长之和。由此，避免LiFi模组开启的第一时长和LiFi模组关闭的第二时长相同，导致第一电子设备与第二电子设备之间永远无法连接的问题。
本申请实施例中，在刚启动第一电子设备，或者，第一电子设备与第二电子设备的LiFi连接断开时，控制LiFi模组关闭并保持第一预设时长。例如，第一预设时长为20s。由此，能够确保第一电子设备与第二电子设备之间能够建立LiFi连接。
步骤203，确定第一电子设备已与第二电子设备建立过LiFi连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第三时长。
其中，第三时长等于第一时长。
本申请实施例中，确定第一电子设备已与第二电子设备建立过LiFi连接，为了确保第一电子设备和第二电子设备可以继续建立LiFi连接，可以控制LiFi模组开启的第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第三时长。
需要说明的是，第一电子设备已与第二电子设备建立过LiFi连接，在判断LiFi模组开启或连接断开时，控制LiFi模组开启并保持第一预设时长，以使得第一电子设备和第二电子设备的LiFi模组开启和与关闭时长同步。
需要说明的是，上述步骤202和步骤203并不是顺序执行的，需要根据步骤201的判断结果，确定仅执行步骤202，还是仅执行步骤203。
本申请实施例的电子设备间的通信控制方法，通过判断第一电子设备是否已与第二电子设备建立过LiFi连接，确定第一电子设备未与第二电子设备建立过连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第二时长，确定第一电子设备已与第二电子设备建立过LiFi连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第三时长。由此，在第一电子设备未与第二电子设备建立LiFi连接时，控制LiFi模组开启的第一占空比，避免了电子设 备间LiFi模组开启的第一占空比相同时，电子设备间无法建立LiFi连接的现象。
在上述实施例的基础上，在步骤103中，控制LiFi模组以第二占空比进行开启并向第二电子设备发送第一心跳包，同时接收第二电子设备发送的第二心跳包时，具体地，可以控制第一电子设备和第二电子设备使用双向通路发送心跳包。下面结合图3对上述过程进行详细介绍，图3为本申请实施例提供的又一种电子设备的通信控制方法的流程示意图。
如图3所示，该通信控制方法还可以包括以下步骤：
步骤301，在第一时间点以第一通路向第二电子设备发送第一心跳包，其中，第二电子设备在第二时间点接收到第一心跳包。
本申请实施例中，确定第一电子设备已与第二电子设备建立LiFi连接，控制第一电子设备在第一时间点以第一通路向第二电子设备发送第一心跳包，以使得第二电子设备在第二时间点接收到第一电子设备发送的第一心跳包。
例如，第一电子设备在T1时刻向第二电子设备发送第一心跳包，第二电子设备在T2时刻接收到第一电子设备发送的第一心跳包。
步骤302，在第三时间点接收第二电子设备发送的第一应答包，并在接收到第一应答包时将LiFi模组关闭第四时长，并在第四时间之后继续发送第一心跳包。
本申请实施例中，第二电子设备接收到第一电子设备发送的第一心跳包后，会向第一电子设备发送第一应答包，以使得第一电子设备在第三时间点接收到第二电子设备发送的第一应答包。第一电子设备在第三时间点接收到第一应答包后，控制LiFi模组关闭第四时长，并在第四时间之后继续发送第一心跳包。由此，保证了电子设备间的功耗最优化。
其中，第四时长为心跳时长减去消息传送时长之后，再减去LiFi模组启动时长。由此，确保了第二电子设备再次接收到第一电子设备发送的第一心跳包之前，第二电子设备的LiFi模组已经开启。
作为一种示例，如图4所示，首先客户端A在第一通路发送信息，客户端B接收到信息后，在第二通道回复信息。由此，可以同步第一通路和第二通路的状态，以保证socket长连接状态下的双通路同步。如图4所示，双通路心跳时间为t3，t3为固定值。对于客户端A来说因为是主动发起方，所以该时间固定。但是对于客户端B来说，因为消息传送时间t0存在波动，如拨动范围在50ms～500ms左右，所以右侧t3实际上会产生波动。
在一种可能的情况下，因为t3固定，所以减去t0后所剩时间t1即为客户端A的LiFi模组关闭时长。但是考虑到LiFi模组开关需要时间(大概100ms),所以需要LiFi模组提前开启，因此客户端A的LiFi模组关闭时间实际为t6。对于客户端B来说，其LiFi模组关闭时间为回复完客户端A消息开始，持续时间为t4，t5则是预留时间，保证在客户端A所发送消息到来前，客户端B的LiFi模组已经开启。
本申请实施例的通信控制方法，通过第一电子设备在第一时间点以第一通路向第二电子设备发送第一心跳包，其中，第二电子设备在第二时间点接收到第一心跳包，第一电子设备在第三时间点 接收第二电子设备发送的第一应答包，并在接收到第一应答包时将LiFi模组关闭第四时长，并在第四时长之后继续发送第一心跳包。由此，确保了电子设备间建立LiFi连接后，电子设备间通信的完整性。
为了实现上述实施例，本申请实施例还提出一种电子设备间的通信控制装置。
图5为本申请实施例提供的一种电子设备间的通信控制装置的结构示意图。
如图5所示，该电子设备间的通信控制装置500，可以包括：判断模块510、第一控制模块520以及第二控制模块530。

作为一种可能的情况，第一控制模块520，还可以用于：
判断第一电子设备是否已与第二电子设备建立过LiFi连接；
确定第一电子设备未与第二电子设备建立过LiFi连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第二时长，其中，第二时长为第一时长与随机时长之和，随机时长小于或等于第一时长。
作为另一种可能的情况，第一控制模块520，还可以用于：
确定第一电子设备已与第二电子设备建立过LiFi连接，则第一占空比包括控制LiFi模组开启的第一时长和控制LiFi模组关闭的第三时长，其中，第三时长等于第一时长。
作为另一种可能的情况，该电子设备间的通信控制装置500，还可以包括：

作为另一种可能的情况，第二控制模块530，还可以用于：

在第三时间点接收所述第二电子设备发送的第一应答包，并在接收到所述第一应答包时将所述LiFi模组关闭第四时长，并在所述第四时长之后继续发送所述第一心跳包。
作为另一种可能的情况，第四时长为：心跳时长-消息传送时长-LiFi模组启动时长。
需要说明的是，前述对电子设备间的通信控制方法实施例的解释说明也适用于该实施例的电子设备间的通信控制装置，此处不再赘述。
本申请实施例的电子设备间的通信控制装置，通过判断第一电子设备是否与第二电子设备建立光保真LiFi连接；确定第一电子设备未与第二电子设备建立LiFi连接，则控制第一电子设备进入扫描模式，其中，在扫描模式之中，控制LiFi模组以第一占空比进行开启；以及确定第一电子设备已与第二电子设备建立LiFi连接，则控制第一电子设备进入连接模式，其中，在连接模式之中，控制LiFi模组以第二占空比进行开启并向第二电子设备发送第一心跳包，同时接收第二电子设备发送的第二心跳包。由此，通过判断第一电子设备与第二电子设备之间是否建立LiFi连接，以控制LiFi模组开启时采用不同的占空比，从而降低了两电子设备的功耗。
