具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白,下面结合实施方式和附图,对本发明做进一步详细说明。在此,本发明的示意性实施方式及其说明用于解释本发明,但并不作为对本发明的限定。
发明人发现:传统的电子标签仅具有一种通信方式,即仅可通过电子标签(还可以称为电子价签)自带的无线通信模块对其进行数据传输和控制。这种通信是单向的,仅可以通过基站设备从后台系统向电子标签推送信息,通过电子价签的输出设备,例如屏幕、LED灯,向用户传递。这种单一的电子标签通信机制较为单一,无法与标签的使用者产生互动,无法快速高效地对电子标签进行控制,无法采集使用者的信息,并反馈给后台系统。
本发明主要提供一种可以实现交互式通信,可通过除基站设备外的其他设备,例如NFC设备,与电子标签进行双向交互式通信,并对电子标签进行高效地控制的方案。更具体地,提供了一种具有两种通信接口的电子标签,电子标签具有一个显示屏,两个通信接口,一个接口可与基站设备进行通信,另一个接口可与NFC(Near Field Communication,近距离无线通讯)设备、磁开关遥控器、红外遥控器等进行通信,实现了灵活地、高效地对电子标签控制,以及与电子标签灵活地、高效地互动。下面对该方案进行详细介绍如下。
图1是本发明实施例中电子标签的结构示意图,如图1所示,该电子标签10包括:
近距离无线通信接口模块11,与外部近距离无线通信设备20无线通信连接,用于接收外部近距离无线通信设备20的读取指令和控制指令;
读取模块12,与所述近距离无线通信接口模块11连接,用于接收所述读取指令,根据所述读取指令,读取电子标签存储模块14中的数据;
第一控制模块13,与所述近距离无线通信接口模块11连接,用于接收所述控制指令,根据所述控制指令,控制改变电子标签的内部数据。
与现有技术中仅可以通过基站设备给电子标签传输数据及进行控制的方式相比较,本发明实施例提供的技术方案通过电子标签的近距离无线通信接口模块接收外部近距离无线通信设备的读取指令和控制指令;读取模块接收该读取指令,根据读取指令,读取电子标签存储模块中的数据;第一控制模块接收控制指令,根据该控制指令,控制改变电子标签的内部数据,实现了与电子标签进行交互式通信,对电子标签高效地控制,提高了电子标签的使用效率。
具体实施时,电子标签的使用者可以是消费者,消费者可以通过近距离无线通信设备发送读取指令,例如该读取指令可以是对某一商品的详细信息的读取指令,电子标签通过近距离无线通信接口模块接收该读取指令,读取模块根据该读取指令,读取电子标签存储模块中的数据,将读取的数据返回给消费者的近距离无线通信的设备,实现了电子标签的使用者主动从电子标签获取所要了解的商品详细信息,提高了消费者的购物体验,以及提高了电子标签的使用效率。
具体实施时,消费者还可以通过近距离无线通信设备发送控制指令,例如该控制指令可以是控制改变电子标签显示内容的控制指令,电子标签通过近距离无线通信接口模块接收该控制指令,第一模块根据该控制指令,控制改变电子标签的显示消费者所需内容,实现了对电子标签的高效地控制,提高了消费者的购物体验,以及提高了电子标签的使用效率。
具体实施时,电子标签的使用者可以是商品的管理人员,商品的管理人员可以通过近距离无线通信设备发送读取指令,例如该读取指令可以是对某一商品的剩余库存信息的读取指令,电子标签通过近距离无线通信接口模块接收该读取指令,读取模块根据该读取指令,读取电子标签存储模块中的数据,将读取的数据返回给商品的管理人员的近距离无线通信的设备,提高了商品的管理人员对商品的管理效率,以及提高了电子标签的使用效率。
具体实施时,商品的管理人员还可以通过近距离无线通信设备发送控制指令,例如该控制指令可以是控制改变电子标签工作状态的控制指令,该工作状态的控制指令可以是改变电子标签的心跳频率(例如该电子标签有隔段时间向基站发出心跳包的功能,该心跳包可以包含电子标签自身工作状态等),例如电子标签的原心跳上报频率是每个隔2小时反馈一次电子标签的自身状态。通过近距离无线通信接口模块接收该控制指令,第一模块根据该控制指令,控制电子标签的工作状态发生改变,例如,将电子标签心跳上报频率是每隔4小时反馈一次电子标签的自身状态,实现了对电子标签的高效控制,提高了商品的管理人员对商品的管理效率,以及提高了电子标签的使用效率。
具体实施时,电子标签的读取模块12接收读取指令,根据所述读取指令,读取电子标签存储模块14中的数据,读取的数据可以包括两类:公共区数据和非公共区数据;其中:
a.公共区数据可通过标准的NFC通信协议进行读取;
b.非公共区数据可通过自定义的数据格式进行读取,需要使用专用的APP。
具体实施时,近距离无线通信接口模块11可以基于NFC通信芯片的通信协议采用标准的NFC协议ISO-14443。近距离无线通信模块可以为:NFC通信芯片模块、磁开关、红外接口模块等。

第二控制模块,用于根据所述外部基站设备发来的控制指令,控制改变电子标签的内部数据。具体实施时,内部数据可以是存储模块14中数据,也可以改变与第一控制模块13一致的数据。
具体实施时,除了上述电子标签的使用者(消费者或商品管理人员)通过近距离无线通信设备对电子标签发送控制指令,高效地控制电子标签,提高电子标签的使用效率的方案之外,还可以根据实际工作需要,通过远距离无线通信接口模块15接收外部基站设备30发来的改变电子标签的存储模块14中数据的指令,第二控制模块16根据改变电子标签的存储数据的指令,改变电子标签的存储模块中数据,实现灵活地、高效地对电子标签的高效互动、控制。在本实施例中提供的电子标签具有两个通信接口,在提高电子标签使用效率的基础上,也提高了电子标签的使用灵活性。
针对两个通信接口具体选用哪个,以提高灵活性,下面举个实例进行说明:例如,在一个实施例中,该电子标签还可以包括喜好分析模块,用于对通过近距离无线通信接口模块接收到的读取指令和控制指令进行分析,得到不同电子标签使用者的喜好信息及电子标签使用者的一些基本信息,这个时候,远距离无线通信接口模块15还可以将电子标签使用者的喜好信息及电子标签使用者的一些基本信息发送至外部基站设备,进而发送给后台系统,供后台系统后续分析商品的喜好者情况等。由于这些电子标签使用者的喜好信息及基本信息不是需要实时性传输的,而是为了后续进行商品分析用的,因此,可以选择远距离无线通信接口模块进行传输即可。
再针对灵活性选择通信接口举一例子,例如,上述电子标签使用者是消费者,消费者需要实时知道电子标签所代表商品实时信息情况时,这个时候,就可以选择近距离无线通信接口模块接收外部近距离无线通信设备的读取指令和控制指令,进一步通过读取模块读取电子标签所代表商品的信息,或是通过第一控制模块控制改变电子标签的内部数据。
