为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附 图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
为了保持本公开实施例的以下说明清楚且简明，本公开省略了部分已知功能和已知部件的详细说明。
因为季节变化、保质日期的临近和营销策略的变化，超市中售卖商品的价格可能变化；对应的，价格标签显示的价格信息也需要对应的更换。
类似的，诸如各种会议中的桌牌也会因为参会人员不同而需要适应地更换(此时，桌牌也可以认为是一种标签)。
目前，价格标签、桌牌仍采用硬拷贝方式制作，改变价格标签、桌牌的显示信息需要更换为包含最新信息的硬拷贝复制件；而制作硬拷贝复制件、更换硬拷贝复制件的过程需要耗费较多资源。例如，为了克服上述问题，采用诸如墨水屏等类型的软拷贝器件制作的电子标签或者电子桌牌得到应用，以避免硬拷贝材料的浪费。
例如，目前市面上的桌牌主要包括两类：
(1)一种是采用纸质或铜质桌签，仅用来显示人名和提示与会者的身份，由于这些桌牌是临时制作的，例如一般是采用打印、彩印、刻字等方式制作，因此，外观会比较粗糙，而且每次都是临时制作，用完即弃，如果与会人数较多，会浪费大量的人力物力，也不环保。
(2)另一种是利用发光二极管显示屏(LED)或液晶显示屏(LCD)显示的电子桌牌，该类电子标签虽然可以反复利用，但是得持续连接上电源才能显示，功耗相对较高。
因此，如何实现大量的电子标签或者电子桌牌显示内容信息快速且便于更新仍是当前亟需解决的问题。
本公开至少一实施例提供一种数据的更新方法，应用于控制装置与电子标签之间的通信，该更新方法包括：接收电子标签发出的无线信号，无线信号包括唯一地表示电子标签的标识；基于无线信号生成响应数据；提取响应数据中的标识；判断是否包括与标识关联的当前标签数据；若是，建立与电子标签的通信连接，并向电子标签发送当前标签数据。
在本公开上述实施例提供的更新方法中，电子标签通过广播的方式向外界发送自身的标识，控制装置可以根据监控得到的标识查询自身存储的信息，确定是否向对应标识的电子标签发送当前标签数据，使得电子标签的显示内容得以更新。在控制装置设置好各个电子标签需要更新的当前标签数据，即可以自动地实现各个电子标签显示内容的更新，实现了标签数据更新效率的提高。
下面结合附图和实施例对本公开公开的实施例作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关发明相关的部分。
为了后续说明的方便，首先对本公开公开至少一实施例提供的方法实施例的可能的应用场景和基础设备结构做一简单地介绍，随后在对本公开公开的实施例提供的方法做详细地说明。
图1A是本公开实施例提供的一种可能应用场景的示意图。如图1A所示，电子标签200为设置在超市货架、用于显示对应位置区域商品价格。电子标签200根据商品的布置方式设置在货架不同的地方；大量的电子标签200组成了电子标签阵列。电子标签200还可以是会议室中的电子桌牌，应于显示参会人员的相关信息。需要注意的是，电子标签200还可以是其他可以显示相关信息的标签，在此不一一举例，本公开的实施例对此不作限制。
例如，为了实现大量电子标签200中数据的更新，应用场景中还设置有控制终端设备11(例如，图1A所示的控制端)。例如，终端设备11可以与各个电子标签200进行无线通信，实现电子标签200数据的更新。例如，该终端设备11与各个电子标签200位于同一空间中，例如，同一会议室或同一排货架上，以有效地接收电子标签200发出的无线信号或向电子标签200发送需要更新的当前标签数据；当然也可以不位于同一空间，只要通过相应的无线通信传送相应的数据即可。
图1B为本公开至少一实施例提供的一种控制装置的示例性结构示意图。例如，如图1B所示，该控制装置100可以包括终端设备11、网络12、服务器13以及数据库14。
终端设备11可以是例如图1B中示出的电脑11-1、手机11-2。可以理解的是，终端设备11可以是能够执行数据处理的任何其他类型的电子设备，其可以包括但不限于台式电脑、笔记本电脑、平板电脑、智能手机、智能家居设备、可穿戴设备、监控设备等。终端设备11也可以是设置有电子设备的任何装备，例如机器人等。
例如，终端设备11采集的无线信号可以通过网络12上传至服务器13，以在服务器13中进行处理或更新，当然，也可以直接在终端设备11的处理器中执行数据的更新操作。
例如，终端设备11通过网络12将监听的无线信号等数据传输给服务器13，终端设备11还可以通过网络12接收服务器13传输的数据，例如，当前标签数据。终端设备11可以通过运行子程序或子线程的方式实施本公开实施例提供的数据的更新方法，以更新数据。
在一些实施例中，可以利用终端设备11的处理器直接执行本公开实施例提供的数据的更新方法。在一些实现方式中，终端设备11可以利用终端设备11内置的应用程序执行数 据的更新方法。在另一些实现方式中，终端设备11可以通过调用终端设备11外部存储的应用程序执行本公开至少一实施例提供的数据的更新方法。
在另一些实施例中，终端设备11将监听到电子标签200发出的无线信号以及基于该无线信号执行数据的更新方法的指令经由网络12发送至服务器13，并由服务器13执行数据的更新方法，以实现电子标签200的数据更新。在一些实现方式中，服务器13可以利用服务器内置的应用程序执行数据的更新方法。在另一些实现方式中，服务器13可以通过调用服务器13外部存储的应用程序执行数据的更新方法。
网络12可以是单个网络，或至少两个不同网络的组合。例如，网络12可以包括但不限于局域网、广域网、公用网络、专用网络等中的一种或几种的组合。
服务器13可以是一个单独的服务器，或一个服务器群组，群组内的各个服务器通过有线的或无线的网络进行连接。一个服务器群组可以是集中式的，例如数据中心，也可以是分布式的。服务器13可以是本地的或远程的。
数据库14可以泛指具有存储功能的设备。数据库13主要用于存储从终端设备11和服务器13工作中所利用、产生和输出的各种数据。例如，数据库14中存储有与电子标签一一对应的当前标签数据或各个电子标签标识等，并将与电子标签一一对应的当前标签数据或各个电子标签标识通过网络12发送至终端设备11，终端设备11基于该与电子标签一一对应的当前标签数据或各个电子标签标识实现操作环境中数据的更新。数据库14可以是本地的，或远程的。数据库14可以包括各种存储器、例如随机存取存储器(Random Access Memory(RAM))、只读存储器(Read Only Memory(ROM))等。以上提及的存储设备只是列举了一些例子，该系统可以使用的存储设备并不局限于此。
数据库14可以经由网络12与服务器13或其一部分相互连接或通信，或直接与服务器13相互连接或通信，或是上述两种方式的结合。
在一些实施例中，数据库15可以是独立的设备。在另一些实施例中，数据库15也可以集成在终端设备11和服务器14中的至少一个中。例如，数据库15可以设置在终端设备11上，也可以设置在服务器14上。又例如，数据库15也可以是分布式的，其一部分设置在终端设备11上，另一部分设置在服务器14上。
需要注意的是，图1B中的终端设备(包括终端设备11-1、终端设备11-2)、网络和服务器的数目仅仅是示意性的。根据实现需要，可以具有任意数目的终端设备、网络和服务器，本公开的实施例对此不作限制。
本公开一些实施例提供一种数据的更新方法应用在控制装置100。例如，该更新方法可以在服务器上执行，且将执行后得到的当前标签数据发送至控制装置100中的终端设备11以进行数据的更新操作，或者可以直接在该控制装置100中的终端设备11的处理器中执行，本公开的实施例对此不作限制。
图2是本公开一些实施例提供的一种数据的更新方法的流程图；如图2所示，本公开实施例提供的数据更新方法包括步骤S100-S104。
步骤S100：接收无线信号。
步骤S101：基于监听到的、电子标签广播的无线信号生成响应数据。
步骤S102：提取响应数据中的标识。
步骤S103：判断是否包括与标识关联的当前标签数据；若是，执行步骤S104；若否，继续执行步骤S100。
步骤S104：建立与电子标签的通信连接，并向电子标签发送当前标签数据。
例如，对于步骤S100和步骤S101，该无线信号为控制装置100监听到的电子标签200发出(即广播)的无线信号。
例如，在电子标签200通电的状态下，其利用自身的通信单元生成广播数据，广播数据即电子标签200向外发射(即广播，下面不再一一解释)的数据。例如，无线信号包括与至少一个电子标签200一一对应的标识，例如采用本领域的方法在广播数据中添加唯一地标识电子标签200的标识后，通过调制方式生成无线信号并向环境辐射。
本公开实施例提供的控制装置100包括第一通信电路，第一通信电路包括通信天线和信号处理器，可以监听周围环境中辐射的、特定频段的无线信号，例如，可以监听并接收电子标签200发射出的无线信号，并对耦合接收到的无线信号进行解调处理、生成与广播数据对应的响应数据。由于该响应数据是基于无线信号生成的，因此该响应数据中也包括发射该无线信号的电子标签200的标识，从而可以在后续更新操作中便于与对应的电子标签200匹配。例如，控制装置100的第一通信电路可以位于终端设备11上，该终端设备11(例如图1A中的控制端)与电子标签200处于同一空间或操作环境中，因此有利于无线信号的监听。
例如，该响应数据是基于无线信号生成的控制装置100可读的数据。本质上其携带的信息和无线信号是一致的，只不过是转化为控制装置100可读的数据而已，当然本公开的实施例对此不作限制。
例如，该信号处理器可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现。该处理单元可以为通用处理器或专用处理器，可以是基于X86或ARM架构的处理器等。
实际应用中，电子标签200中的通信单元和控制装置100的第一通信电路可以是各种已知的无线通信单元，例如蓝牙通信单元。
例如，对于步骤S102，在得到响应数据后，控制装置100根据预定的协议规则对响应数据进行解析，并获得其中的标识。电子标签200与标识一一对应，即每个标识都唯一地表示一个电子标签200，即一个标识对应一个电子标签200。因为标识具有唯一性，所以根据标识，控制装置100可以确定发出无线信号的电子标签为哪一个电子标签。
例如，可以提供第一提取电路，并通过该第一提取电路提取响应数据中的标识；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程 逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该第一提取电路。
对于步骤S103，例如，控制装置100内设置有存储单元，存储单元用于存储需要更新的电子标签200的标识、需要更新的当前标签数据，并且每个当前标签数据具有对应的标识。此处请注意，仅是每个当前标签数据具有对应的标识，但是并不一定每个标识均具有对应的当前标签数据。
例如，在获取到标识后，控制装置100根据标识查找存储单元的信息，判断是否有对应的标识；如果有对应的标识，则判断标识是否有对应的当前标签数据；如果查找到对应的当前标签数据，则判定该标识表示的电子标签200的显示内容需要更新。
例如，可以建立标识与当前标签数据的查找表，在获取到标识后，控制装置100根据标识查找存储单元的信息，判断是否有对应的标识，如果有对应的标识，则在查找表中查找是否标识有对应的当前标签数据；当然还可以通过其他方法判断，本公开的实施例对此不作限制。
例如，可以提供第一判断电路，并通过该第一判断电路判断是否包括与标识关联的当前标签数据；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该第一判断电路。
对于步骤S104，
在确定标识代表的电子标签200需要更新显示内容后，控制装置100向对应的电子标签200发出建立连接的请求信号，以与对应的电子标签200建立通信连接。
具体地，控制装置100包括第一通信电路，并通过第一通信电路发送请求信号，并在请求信号中添加前述的标识或者对应标识的MAC地址，以通知对应的电子标签200与控制装置100建立通信连接。
根据采用的通信单元的不同，建立通信连接的具体过程采用对应的步骤，在此本公开不再复述，相关技术可以参见本领域内的相关介绍。
在控制装置100与电子标签200建立通信连接后，向电子标签200下发当前标签数据；电子标签200在成功接收到当前标签数据后，利用标签数据更新显示内容，使得当前标签数据得以显示。
采用本公开实施例提供的数据的更新方法，电子标签200通过广播的方式向外界发送自身的标识，控制装置100可以根据监控得到的标识查询自身存储的信息，确定是否向对应标识的电子标签200发送当前标签数据，使得电子标签200的显示内容得以更新。在控制装置100设置好各个电子标签200需要更新的当前标签数据，即可以自动地实现各个电子标签200显示内容的更新，实现了标签数据更新效率的提高。
本公开实施例中，各个电子标签200均以一定的频率广播无线信号；而控制装置100随机地监听各个电子标签200发送的无线信号，实现对应电子标签200的标签数据的更新； 通过一段的时间，各电子标签200的数据内容都得以更新。
例如，本公开另一些实施例提供的数据的更新方法也是应用在控制装置100侧。图3是本公开另一些实施例提供的数据的更新方法的流程图；如图3所示，该实施例提供的方法包括步骤S201-S204。例如，图3所示的更新方法和图2所示的更新方法基本相同，区别在于：在图2所示的示例的基础上，该无线信号还包括电子标签200的当前数据的更新时间。下面结合图3对本公开另一些实施例提供的数据的更新方法进行详细地介绍。
步骤S201：基于监听到的、电子标签广播的无线信号生成响应数据。
本公开实施例中，电子标签利用自身的通信单元生成广播数据，并调制广播数据后生成无线信号，向环境中辐射无线信号。前述的广播信号中包括唯一地表示电子标签200的标识和电子标签200当前数据的更新时间。
本公开实施例提供的控制装置100包括第一通信电路，第一通信电路包括通信天线和信号处理器，可以监听周围环境中辐射的、特定频段的无线信号，并对耦合到的无线信号进行解调处理、生成与广播数据对应的响应数据。
关于该步骤中与图2类似部分的具体介绍可参考步骤S101中的介绍，在此不再赘述。
步骤S202：提取响应数据中的标识和当前数据的更新时间。
在得到响应数据后，控制装置100根据预定的协议规则对响应数据进行解析，并获得其中的标识和当前数据的更新时间。因为标识具有唯一性，所以根据标识，控制装置100可以确定发出无线信号的电子标签200为哪一个电子标签200，以及对应当前标签数据的更新时间。
本公开实施例中，当前数据的更新时间是电子标签200当前数据对应的历史标签数据的制作时间，还可以是电子标签200接收到当前数据对应的历史标签数据的时间，或者，更新显示当前数据的时间，本公开的实施例对此不作限制。
例如，在该示例中，第一提取电路还配置为提取响应数据中的当前数据的更新时间。
关于该步骤中与图2类似部分的具体介绍可参考步骤S102中的介绍，在此不再赘述。
步骤S203：判断是否有与标识关联的、时间属性晚于更新时间的当前标签数据；若是，执行S204；若否，执行S201。
例如，控制装置100内设置有存储单元，存储单元用于存储需要更新的电子标签200的标识、需要更新的当前标签数据以及当前标签数据的时间属性，并且当前标签数据具有对应的标识。
例如，当前标签数据的时间属性可以是电子标签200当前标签数据的制作时间，本公开的实施例对此不作限制。
在获取到标识后，控制装置100根据标识查找存储单元的信息，判断是否有对应的标识；如果有对应的标识，则判断标识是否有对应的当前标签数据；如果查找到对应的当前标签数据，则继续判断当前标签数据的制作时间是否晚于当前数据的更新时间；如果标签的制作时间晚于当前数据的更新时间，则判定标识代表的电子标签200的显示内容需要更 新。
例如，在该示例中，第一判断电路还配置为判断是否有与标识关联的、时间属性晚于更新时间的当前标签数据。
关于该步骤中与图2类似部分的具体介绍可参考步骤S103中的介绍，在此不再赘述。
步骤S204：建立与电子标签的通信连接，并向电子标签发送当前标签数据。
例如，在确定标识代表的电子标签200需要更新显示内容后，控制装置100向对应的电子标签200发出建立连接的请求信号，以与对应的电子标签200建立通信连接。
在控制装置100与电子标签200建立通信连接后，向电子标签200发送当前标签数据；电子标签200在成功接收到当前标签数据后，根据当前标签数据更新显示内容，使得当前标签数据被显示。
关于该步骤中与图2类似部分的具体介绍可参考步骤S104中的介绍，在此不再赘述。
需要注意的是，图3所示的更新方法还可以包括图2中所示的步骤S100，本公开的实施例对此不作限制。
除了具有图2所示的实施例提供的更新方法的技术方案产生的技术效果外，图3所示的实施例提供的更新方法的技术方案还具有以下技术效果：在确定标识具有对应的当前标签数据后，通过比较当前标签数据对应的日期是否晚于电子标签200当前数据的更新时间，判定电子标签200显示的数据是否为最新数据，继而确定是否需要对电子标签200的显示内容进行更新；如果需要对电子标签200的显示内容进行更新，则建立与电子标签200的通信连接；如果不需要对电子标签200的显示内容进行更新，则不再与之连接。这一方案避免了控制装置100与一个电子标签200重复连接下发标签数据的问题。
另外，采用本公开实施例提供的更新方法，可以对控制装置100中存储的单条数据进行修改，实现数据操作的方便性。
具体应用中，控制装置100可以与远程数据库通信连接，按照预设时间间隔从远程数据库下载信息，以更新自身存储的标签数据信息。
本公开实施例中，无线信号中包含的电子标签200当前数据的更新时间是当前数据对应的历史标签数据的制作日期；在其他实施例中，前述的更新时间也可以是电子标签200接收到当前数据对应的历史标签数据的时间，或者更新当前数据的时间。
另外，在其他实施例中，电子标签200也可以不发送前述的更新时间，而是控制装置100向对应的电子标签200下发当前标签数据后，删除对应的当前标签数据，以避免当前标签数据在不同更新时间的重复发送。
如前所述，本公开提供的控制装置100用于与多个电子标签200进行连接，实现多个电子标签200显示内容的更新；因此，在执行完步骤S104或者步骤S204后，控制装置100还可以断开与电子标签200的通信连接，并再继续监听无线信号、实现与其他电子标签200的连接。
具体实施中，为保证数据下发正确，控制装置100可以在接收到电子标签200发送的 接收成功消息后，再断开与电子标签200的通信连接。
例如，控制装置100还接收电子标签200发送的返回信号，生成返回数据；判断返回数据是否包含当前标签数据接收完毕信息；在判定返回数据包含当前标签数据接收完毕信息时，断开与电子标签200的通信连接。当然还可以采用本领域的其他方法实现通信连接的判断，本公开的实施例对此不作限制。
本公开的一些实施例还提供一种数据的更新方法，应用在电子标签200。图4是本公开一些实施例提供的数据的更新方法流程图。如图4所示，本实施例提供的方法包括步骤S301-S306。
步骤S301：生成并发射无线信号。
例如，电子标签200生成并广播无线信号。电子标签200在上电工作后，其利用自身的通信单元生成广播数据，并在广播数据中添加唯一地标识电子标签200的标识后，基于广播数据生成无线信号，并将无线信号向环境中辐射。
步骤S302：监听连接请求信号，生成连接请求数据。
例如，在控制装置100接收到无线信号，并确定需要与特定的电子标签200连接后，会生成连接请求数据，并将特定电子标签200的标识作为标签信息添加到连接请求数据，并将连接请求数据调制后生成连接请求信号。
例如，电子标签200监听连接请求信号，在监听到连接请求信号后、对其进行解调并生成连接请求数据。
步骤S303：提取连接请求数据中的标签信息。
例如，在获得连接请求数据后，电子标签200按照预设规则提取其中的标签信息，并用于后续判断。
步骤S304：判断标签信息是否与自身的标识相同；若是，执行步骤S305；若否，继续执行步骤S301和步骤S302。
例如，如果标签信息与电子标签200自身的标识相同，则证明控制装置100请求建立与电子标签200的通信连接；此时即可以执行步骤S305。
步骤S305：建立与控制装置的通信连接；接收控制装置发送的当前标签数据。
步骤S306：将当前标签数据用于显示。
例如，电子标签200与控制装置100建立通信连接的过程根据二者采用的通信协议、无线通信方式的不同而不同，具体可以参见本领域中不同无线通信协议的连接方式，在此不再复述。
例如，电子标签200建立与控制装置100的通信连接，电子标签200接收当前标签数据。并在当前标签数据接收完成后，显示当前标签数据。
电子标签200用于显示当前标签数据的显示部件可以是本领域的各种软拷贝输出结构，例如LCD屏、墨水屏等。考虑到墨水屏技术具有成本低、耗电少的优点，电子标签200的显示部件可以通常选用墨水屏。
例如，电子标签200接收到当前标签数据后，通过SPI(Serial Peripheral Interface，串行外设接口)的方式，输出至输出结构(例如，上述墨水屏)进行显示。
本公开实施例提供的数据更新方法中，电子标签200向周围环境发送广播信号以告知控制装置100自身的标识，如果控制装置100需要更新相应的标识的数据时，利用标识与对应的电子标签200建立连接，并下发当前标签数据。采用这样的方法，在不确定实际环境电子标签200数量和标识的情况下，电子标签200作为主动方触发控制装置100启动连接，实现了相应标签数据的自动更新。
具体应用中，在执行步骤S305后，特别是在电子标签200验证接收当前标签数据成功后，可以断开与控制装置100的通信连接，并进入低耗状态。而低耗状态维持一定的时间后(例如可以是一天)，电子标签200继续广播无线信号，以探听是否有相应的连接请求信号、实现数据的再次更新。
此外，在一些应用中，例如在电子桌牌应用场合，也可以由工作人员控制电子标签200上电工作，继而启动是否继续广播(即向外界环境发射)无线信号。本公开实施例中，电子标签200广播的无线信号除了包括前述的标识外，还可以包括其当前数据的更新时间；具体应用中，更新时间可以是电子标签200接收当前数据对应的历史标签数据的时间、更新显示当前数据的时间、当前数据对应的历史标签数据的制作时间。
而具体应用中，前述的标识可以是电子标签200的MAC地址、电子标签200所在的位置地址，或者电子标签200用于标识的产品信息。例如，电子标签200所在的位置地址可以是超市货架的货架位置、电子桌牌所在位置的行列排布。
例如，本公开又一些实施例提供的数据更新方法可以用于控制装置100和电子标签200组成的系统。图5是本公开又一些实施例提供的一种数据的更新方法的流程图。如图5所示，本公开的实施例提供的更新方法包括步骤S401-步骤S405。
步骤S401：电子标签生成并发射无线信号。
例如，电子标签200在上电工作后，其利用自身的通信单元生成广播数据，并在广播数据中添加唯一地标识电子标签200的标识后，将广播数据以无线信号向环境中辐射。
例如，关于该步骤S401的相关介绍可以参考图4中所示的步骤S301的相关描述，在此不再赘述。
步骤S402：控制装置基于监听到的、电子标签广播的无线信号生成响应数据。
例如，本公开实施例提供的控制装置100包括第一通信电路，第一通信电路包括通信天线和信号处理器，可以监听周围环境中辐射的、特定频段的无线信号，并对耦合到的无线信号进行解调处理、生成与广播数据对应的响应数据。
例如，关于该步骤S402的相关介绍可以参考图2中所示的步骤S101或图3中所示的步骤S201的相关描述，在此不再赘述。
步骤S403：控制装置提取响应数据中的标识。
例如，关于该步骤S403的相关介绍可以参考图2中所示的步骤S102或图3中所示的 步骤S202的相关描述，在此不再赘述。
步骤S404：判断是否有与标识关联的当前标签数据；若是，执行步骤S405；若否，使控制装置执行步骤S402，使电子标签执行步骤S401。
例如，控制装置100内设置有存储单元，存储单元用于存储需要更新的电子标签200的标识、需要更新的当前标签数据，并且每个当前标签数据具有对应的标识(此处请注意，仅是每个当前标签数据具有对应的标识，但是并不一定每个标识均具有对应的当前标签数据)。
在获取到标识后，控制装置100根据标识查找存储单元的信息，判断是否有对应的标识；如果有对应的标识，则判断标识是否有对应的当前标签数据；如果查找到对应的标签数据，则判定标识代表的电子标签200的显示内容需要更新。
例如，关于该步骤S404的相关介绍可以参考图2中所示的步骤S103或图3中所示的步骤S203的相关描述，在此不再赘述。
步骤S405：建立控制装置与电子标签的通信连接，控制装置向电子标签下发所述当前标签数据，并使电子标签显示当前标签数据。
例如，在确定标识代表的电子标签200需要更新显示内容后，控制装置100向对应的电子标签200发出建立连接的请求信号，以与对应的电子标签200建立通信连接。
例如，在控制装置100与电子标签200建立通信连接后，向电子标签200下发当前标签数据；电子标签200在成功接收到当前标签数据后，根据当前标签数据更新显示内容，使得当前标签数据被显示。
例如，关于该步骤S405的相关介绍可以参考图2中所示的步骤S104或图3中所示的步骤S204的相关描述以及图4所示的步骤S305和步骤S306的相关描述，在此不再赘述。
本公开实施例提供的数据的更新方法，电子标签200通过广播的方式向外界发送自身的标识，控制装置100可以根据监控得到的标识查询自身存储的信息，确定是否向对应标识的电子标签200发送当前标签数据，使得电子标签200的显示内容得以更新。在控制装置100设置好各个电子标签200需要更新的当前标签数据，即可以自动地实现各个电子标签200显示内容的更新，实现了标签数据更新效率的提高。
与前述图3所示的实施例和图4所示的实施例类似，本公开实施例提供的数据的更新方法中，电子标签200发送的无线信号还可以包括电子标签200当前数据的更新时间；对应的，在步骤S404判断是否与标识关联的当前标签数据，可以包括：判断是否有与标识关联的、时间属性晚于更新时间的当前标签数据。前述的更新时间可以是电子标签200接收当前数据对应的历史标签数据的时间、更新显示当前数据的时间、当前数据对应的历史标签数据的制作时间等。
在确定标识具有对应的当前标签数据后，通过比较当前标签数据对应的日期和晚于电子标签200当前数据的更新时间，判定电子标签200显示的数据是否为最新数据，继而确定是否需要对电子标签200的显示内容进行更新；如果需要对电子标签200的显示内容进 行更新，则建立与电子标签200的通信连接；如果不需要对电子标签200的显示内容进行更新，则不再与之连接。这一方案避免了控制装置100与一个电子标签200重复连接下发标签数据的问题。
更进一步地，在执行步骤S405后，断开控制装置100与电子标签200的通信连接，并可以使电子标签200继续生成并广播无线信号。
在前述各个实施例中，控制装置100和电子标签200之间的通信可以采用已有的通信协议，也可以采用一些自定的通信协议，对此本公开并不做特别限定。在一个具体应用中，控制装置100和电子标签200采用蓝牙通信协议，并对协议传输的数据进行了适当的修改。
具体地，传输格式包括命令格式和数据格式。例如，命令格式为：AA+AA+00+LengthH+Lengthl+A0+Command(1)+Checksum(3)+0D+0A，例如，AA+AA+00为命令头三个字节，LengthH为命令长度高字节，LengthL为命令长度低字节，A0为命令指示标志，其占一个字节，Command为具体命令参数一个字节，Checksum为命令校验和占三个字节，0D+0A为命令结束符，占两个字节。数据格式为：AA+AA+00+LengthH+LengthL+55+AP+MAC(6)+datacount(1)+datanum(1)+data(256)+checksum(3)+0D+0A，AA+AA+00为数据包头三个字节，LengthH为数据包长度高字节，LengthL为数据包长度低字节，55为数据指示标志一个字节，AP为指示由那个AP发送数据包，MAC为数据包发送到具体电子标签200，其占6个字节，DataCount为数据包序列号，DataNum为数据包总个数，Data为数据包有效长度1-1024个字节，CheckSum为数据校验和，其占三个字节，0D和0A为数据包结束符占两个字节。

首先，电子桌牌端将自身唯一的MAC地址标识，添加到广播数据中。
其次，控制装置100扫描所有周围的广播数据，进行分析、判断，决定是否建立连接。
例如，控制装置100在进行采用上述方法进行分析判断后，决定由哪个电子桌牌来建立连接。
最后，启动建立连接后，控制装置100和电子桌牌端按照上述相应的传输协议，将当前标签数据发送到电子桌牌端，并显示在显示屏(例如，墨水屏)上。
