【附图说明】
图1是本发明的可穿戴设备一实施例的结构示意图；
图2是本发明可穿戴设备进行数据收发的方法一实施例的流程图；
图3是本发明的可穿戴设备另一实施例的结构示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明所提供的示例性的实施例的技术方案进行清楚、完整地描述。
图1是本发明的可穿戴设备一实施例的结构示意图。如图1所示，所述可穿戴设备10包括第一微控制单元(Micro controller Unit，MCU)11和通讯模块12。在可穿戴设备10需要与外部终端进行数据收发时，所述通讯模块12基于无线通信协议与外部终端建立连接，并在建立连接之后所述通讯模块12基于数据传输协议(例如Transmission Control Protocol/Internet Protocol，简称TCP/IP协议，又称传输控制协议/因特网互联协议或网络通讯协议)在第一微控制单元11和外部终端之间进行数据收发。所述数据收发应该被理解为：所述通讯模块12将第一微控制单元11所要发出的数据传输给外部终端，以及通讯模块12将外部终端所要发出的数据传输给第一微控制单元11。其中，所述外部终端既可以理解为手机、电脑等便携式通讯装置，也可以理解为服务器。
区别于现有技术，本发明实施例的通讯模块12也包括一个MCU-第二微控制单元121，且该第二微控制单元121集成有一个通讯单元1211，该通讯单元1211支持前述无线通信协议和数据传输协议。在可穿戴设备10需要与外部终端进行数据收发时，第一微控制单元11与第二微控制单元121连接，第二微控制单元121的通讯单元1211基于无线通信协议与外部终端建立无线连接，射频单元122基于数据传输协议在第一微控制单元11和外部终端之间进行数据收发。
也就是说，本发明实施例将数据传输协议和无线通信协议从可穿戴设备10的MCU(操作***)中独立开来，这样既可以确保无线连接的稳定性，也可以确保可穿戴设备10的操作***的运行性能。同时，能够简化可穿戴设备10的操作***，降低开发可穿戴设备10的操作***的工作量。并且，也便于后期查找与分析无线连接、数据传输及操作***的故障原因，提高软件开发效率的同时降低软件开发风险。
在本发明实施例中，所述通讯模块12进行数据收发的数据可以为内置或外设于可穿戴设备10的传感装置13所采集到的传感数据，其中传感装置包括麦克风、摄像头、加速度检测设备、温度传感器等。该传感装置13与第一微控制单元11连接，从而将采集到的传感数据传输给第一微控制单元11，第一微控制单元11将传感数据传输给第二微控制单元121，第二微控制单元121将传感数据传输给射频单元122，最后由射频单元122将传感 数据传输给外部终端。
当然，可穿戴设备10也可以从外部终端接收其他类型数据，具体而言，第二微控制单元121接收外部终端所发出的外部数据，并将外部数据传输给第一微控制单元11。
优选地，传感装置13和第一微控制单元11之间可以通过第一类型接口进行连接，射频单元122和第一微控制单元11之间可以通过第二类型接口进行连接。其中，第一类型接口可以为I2C(Inter-Integrated Circuit，两线式串行总线)接口，第二类型接口可以为UART(Universal Asynchronous Receiver/Transmitter，通用异步收发传输)串口，当然第二类型接口可以为I2C接口。也就是说，传感装置13和第一微控制单元11之间与射频单元122和第一微控制单元11之间可以采用相同类型的接口也可以采用不相同类型的接口。
进一步地，本发明实施例的所述无线通信协议可以为Wi-Fi协议或蓝牙Bluetooth协议。以Wi-Fi协议为例，软件开发所要编程的Wi-Fi软件架构分为多层架构，其包含的MAC(Media Access Control，介质访问控制)地址，基带(Baseband)及无线(Radio)信息运行在通讯模块12的RF(Radio Frequency，射频)芯片中。另外，例如为TCP/IP协议的数据传输协议以及Driver，Supplicant，TLS/S SL(Secure Sockets Layer，安全套接层/Transport Layer Security，传输层安全)信息，Protocols(协议)信息以及Application(应用程序)信息运行在通讯模块12的第二微控制单元121中。这些软件程序对MCU的运行频率、OS(Operating System，操作***)的响应时间以及RAM大小都有严格要求，所以如果将这些软件程序移植到可穿戴设备10的操作***中并与其操作***相兼容，需要很大的软件移植工作量，并且受制于硬件因素，即使能够实现无线连接，其连接的稳定性以及可穿戴设备10的操作***的运行性能也会受到很大的影响。而本发明实施例将Wi-Fi协议软件运行在通讯模块12中独立的MCU(即第二微控制单元121)中，与可穿戴设备10的操作***没有直接关联，只有在进行数据收发时才与可穿戴设备10的操作***关联，因此可避免软件开发的风险和难度。
图2是本发明可穿戴设备进行数据收发的方法一实施例的流程图。如图2所示，所述可穿戴设备进行数据收发的方法包括：
S21：在通讯模块中设置第二MCU，且第二MCU中集成有通讯单元，通讯单元支持数据传输协议和无线通信协议，其中第二MCU和可穿戴设备的操作***所在的第一MCU相独立。
S22：在可穿戴设备与外部终端进行数据收发时，第一MCU与第二MCU连接，第二MCU的通讯单元基于无线通信协议与外部终端建立无线连接，通讯模块的射频单元基于数据传输协议在第一MCU和外部终端之间进行数据收发。
本实施例的数据收发的方法的各个步骤可由具有上述结构的可穿戴设备10对应执行，具有与其相同的技术效果。
请参阅图3，为本发明另一实施例的可穿戴设备。所述可穿戴设备30包括第一MCU 31、第二MCU 32和射频天线33，第二MCU 32包括处理器321和存储器322且集成有无线网卡333，无线网卡333支持网络通讯TCP/IP协议和无线通信协议，存储器322存储有程序，该程序用于实现可穿戴设备30与外部终端之间的数据收发。处理器321、存储器322、无线网卡333以及射频天线33之间相连接。
