具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
物联网终端与物联网网关之间大多采用近场无线通信的方式，物联网网关将物联网终端上报的信息，通过有线网络或者移动网络发送给物联网服务器，物联网服务器则将信息下发给物联网网关，通过物联网网关发送给物联网终端，在物联网终端上进行显示。物联网终端的一具体应用可以为医院床头卡，床头卡位于病床旁，用于显示病患信息；物联网终端的另一具体应用可以为胸卡终端，用来显示员工信息；物联网终端的另一具体应用还可以为病房或会议门牌等，用于显示病房内或会议室内的相应的信息。物联网终端所显示的信息，通过物联网服务器-物联网网关下发到物联网终端。
物联网终端在显示图片时，通过物联网服务器-物联网网关将图片信息推送至物联网终端，即将在物联网终端上显示的内容，物联网服务器以图片数据格式的方式通过物联网网关发送给物联网终端，物联网终端将收到的图片数据存贮在物联网终端电路板上的Flash内。显示消息内容为单幅图片时，物联网终端可以将图片信息直接进行显示。当物联网服务器推送多个关联的图片信息时，物联网终端可以直接显示第一幅图片，用户能够看到；对于剩余 的图片，通过LED闪烁指示的方法提醒用户还有其他图片，用户看到后，可以通过按键操作物联网终端，来进行其他图片的显示。由于LED指示灯有几mA的电流，因此对于低功耗要求的物联网终端，LED指示灯不能长期闪烁，只能定时闪烁后关掉。如果用户没有及时看到闪烁的LED指示灯，由于LED指示灯定时闪烁后熄灭，用户将不会知道还有其他的图片，如果通过随机按翻页按键来确认是否还有其他图片，不但会引起物联网终端从低功耗休眠状态切换至正常工作模式，有一定的能量消耗，导致物联网终端待机时间的缩短，而且会给用户带来不好的用户体验。
本公开实施例提供一种图片更新方法、物联网终端及物联网系统，能够实现低功耗的物联网终端完成图片类的处理。
本公开的实施例提供一种物联网终端，如图1所示，包括：
通信单元11，用于接收物联网网关发送的文字图像信息，所述文字图像信息包括合成后的图片信息和页码信息，所述页码信息指示所述图片信息对应的图片在关联的多幅图片中的页码以及所述关联的多幅图片的总页码；通信单元11可以通过射频、蓝牙等无线方式接收文字图像信息，也可以通过有线方式接收文字图像信息；
与所述通信单元11连接的微控制单元12，用于将所述文字图像信息转换为待显示的图片，所述待显示的图片包括页码信息；
与所述微控制单元12连接的存储单元13，用于存储所述待显示的图片；
与所述微控制单元连接的显示单元14；
所述微控制单元12还用于从所述存储单元13读取所述待显示的图片写入所述显示单元14进行显示。
本实施例中，通信单元接收到的文字图像信息包括页码信息，微控制单元将通信单元接收到的文字图像信息转换为待显示的图片存储在存储单元中，之后微控制单元将存储单元存储的待显示的图片写入显示单元进行显示，显示单元显示的图片包括有图片的页码，这样可以使得物联网用户获知当前显示的图片是第几页，以及除当前显示的图片之外还有多少关联的图片，无需通过LED闪烁指示的方法提醒用户有其他关联的图片，能够降低物联网终 端的功耗，提高物联网终端的待机时间；本实施例还可以改善用户的体验。
一具体示例中，通信单元11为射频芯片，可以通过无线方式与物联网网关进行通信，通过物联网网关与物联网服务器进行交互，接收文字图像信息。其中，物联网网关可以进行近场的无线通信，并具有无线网络或者有线网络，能够连接物联网服务器。
存储单元13用于信息存储以及文字图像信息处理过程中的信息缓存，存储单元13可以采用多种类型的存储器件，一些实施例中，存储单元13可以采用闪存Flash，它的主要特点是在不加电的情况下能长期保持存储的信息。Flash属于EEPROM(电擦除可编程只读存储器)类型，它具有很高的存取速度，而且易于擦除和重写，功耗很小，适用于具有低功耗要求的物联网终端。当然，存储单元13并不局限于采用Flash，还可以采用其他类型的可擦除可编程的存储器件。
一些实施例中，所述显示单元14为电子墨水屏。电子墨水屏的功耗非常低，适用于具有低功耗要求的物联网终端。当然，显示单元14并不局限于采用电子墨水屏，还可以采用其他类型的低功耗显示器件。
本实施例中，所述微控制单元12与所述通信单元11之间可以通过串行外设接口连接；所述微控制单元12与所述存储单元13之间可以通过串行外设接口(Serial Peripheral Interface，SPI)连接；所述微控制单元12与所述显示单元14之间可以通过串行外设接口连接；串行外设接口是一种同步外设接口，它可以使微控制单元12与各种外围设备以串行方式进行通信以交换信息。
一些实施例中，所述文字图像信息包括多组信息，每组信息包括图片信息及与所述图片信息对应的页码信息；
所述通信单元具体用于分别接收所述多组信息；其中，分别接收可以有先后顺序也可以没有先后顺序；
所述微控制单元具体用于将所述多组信息分别对应转换为多个待显示的图片；
所述存储单元具体用于存储所述多个待显示的图片，所述多个待显示的 图片在所述存储单元中对应的存储区域相互独立；
