具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施 例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动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。
本公开一些实施例提供的电子标签包括电子标签本体和被配置为向电子标签本体供电的供电电源；结合图1和图2所示，电子标签本体10包括外壳11、设置于外壳11内的传感器13和主控制器14,以及被配置为进行信息显示的显示屏12。
传感器13和主控制器14在图1中所示的设置位置仅为示意，在实际的产品中可以有更合适的设置位置；并且可以理解的是，在实际的产品中，位于壳体11内的元器件，例如传感器13、主控制器14、供电电源40、以及后文将要提到的微型风扇15、开关电路等，均被壳体11所遮挡而不可见，在图1中将其示出为可见仅仅是为了辅助说明和理解。
传感器13被配置为检测该电子标签本体10所处环境的环境温度。
主控制器14，被配置为在传感器13检测的环境温度处于显示屏12工作温度范围之外的情况下，停止向显示屏12供电。
结合图1和图3所示，上述电子标签所包括的供电电源40被配置为向电子标签本体10供电，即，向主控制器14、传感器13、微型风扇15(后文将要描述)和显示屏12等供电。
外壳
外壳11为内部具有空腔的结构，以使传感器13、主控制器14、微型风扇15等可以设置于外壳11内。
传感器13、主控制器14、开关电路可设置于线路板上。对于微型风扇15，其可直接设置于线路板上，也可固定于外壳11内合适的位置，以在微型风扇15开启时，能对显示屏12甚至电子标签本体10进行有效散热为准。
外壳11可采用轻量化的注塑一体成型工艺形成，以使电子标签本体10的重量较轻。
显示屏
显示屏12与主控制器14连接，由主控制器14控制信息显示。
对于显示屏12的设置方式，例如可以是：在外壳11的正面上设置开口，显示屏12位于外壳11内，且显示屏12的显示区域与外壳11正面的开口对应(参考图1所示)。
显示屏12的工作温度在C1～C2范围，其中，C1＜C2。基于此，环境温度(记为D)处于显示屏12的工作温度范围之外，即，D＞C2，或者，D＜C1。
应当理解的是，虽然当环境温度处于显示屏12的工作温度范围之外，会停止向显示屏12供电，但为保证电子标签的正常使用，当环境温度处于显示屏12的工作温度范围之内时，会重新向显示屏12供电。
停止向显示屏12供电，即，使供电电源与显示屏12的连接断开；重新向显示屏12供电，即，使供电电源与显示屏12连接。
由于电子纸显示屏只有在刷新时才消耗电流，其它时间都处于低功耗状态，因此，在本公开的一些实施例中可采用电子纸显示屏作为显示屏12。示例的，选用4.2寸电子纸显示屏作为本公开一些实施例中的显示屏12。
电子纸显示屏工作温度范围为0～50℃。本领域技术人员明白，以0～50℃为例，电子纸显示屏工作温度包括了0℃和50℃，其他数值范围也类似。
传感器
对于传感器13而言，其工作温度范围应将显示屏12的工作温度范围包括在内，即传感器13可以在显示屏12的工作温度范围内工作。传感器13的工作温度在B1～B2范围，B1＜B2。如上所述，显示屏12的工作温度在C1～C2范围。B1＜C1，B2＞C2。
传感器13可以为温湿度传感器。即，温湿度传感器既可以检测温度还可以检测湿度。
温湿度传感器的工作温度范围可以为-40℃～125℃，精度误差0.3℃以内，相对湿度精度误差2％RH以内，可满足车载环境使用要求。
供电电源
供电电源40可以是设置在电子标签的外壳11内的电池，也可以是通过电源线与电子标签连接的外部电源，或者是二者兼而有之。由于电子标签的可移动性，因此供电电源40大部分情况下均以电池的形式提供。电池可以是一次性电池或者可充电电池，外部电源可以是太阳能电源或车载电源。
下面以供电电源40包括太阳能电源和可充电电池的情形进行说明。
在本公开的一些实施例中，如图6所示，供电电源40包括：太阳能电池板41、充电电路42、锂离子电池43和DC-DC(直流转直流)转换器44；太阳能电池板41通过充电电路42和锂离子电池43连接；太阳能电池板41和锂离子电池43还各通过一个二极管与DC-DC转换器44的输入端连接。
太阳能电池板41可设置于外壳11的外部以接收太阳光；充电电路42、锂离子电池43和DC-DC转换器44可设置于电子标签本体10的外壳11内，即，充电电路42、锂离子电池43和DC-DC转换器44可设置于线路板上。
太阳能电池板41和锂离子电池43各通过一个二极管与DC-DC转换器44的输入端连接，即，如图6所示，太阳能电池板41通过第一二极管D1与DC-DC转换器44的输入端连接，锂离子电池43通过第二二极管D2与DC-DC转换器44的输入端连接。在此基础上，可以理解的是，DC-DC转换器44的输出端被配置为向电子标签供电。
上述供电电源40的供电方式为：当太阳能电池板41输出电压高于锂离子电池43时，第一二极管D1导通，第二二极管D2截止，太阳能电池板41向DC-DC转换器44的输入端供电，同时太阳能电池板41通过充电 电路42给锂离子电池43充电；当太阳能电池板41输出电压低于锂离子电池43时，第二二极管D2导通，第一二极管D1截止，锂离子电池43向DC-DC转换器44的输入端供电，同时充电电路42停止工作；当太阳能电池板41输出电压等于锂离子电池43时，可由太阳能电池板41和锂离子电池43共同向DC-DC转换器44的输入端供电，在此情况下，太阳能电池板41、锂离子电池43和DC-DC转换器44输入端的电压相等。
示例的，锂离子电池43可采用3.7V锂离子电池。太阳能电池板41可采用多晶太阳能电池板，其尺寸小、输出电压5V、峰值电流高达120mA，完全可为3.7V锂离子电池充电。充电电路42可采用支持恒流/恒压线性充电的芯片(如TP4056)，充电电流大小可调整，并具备过热保护功能。其中，在充电电路42采用TP4056芯片的情况下，当太阳能电池板41输出的电压高于锂离子电池43电压30mV以上，充电电路42便可为锂离子电池43充电。DC-DC转换器44可采用微功耗低噪声LDO(Low Dropout Regulator，低压差线性稳压器)(如LT1962)。
在本公开的一些实施例中，通过采用太阳能电池板41、充电电路42、锂离子电池43和DC-DC转换器44等构成供电电源40，无需外部供电，节能环保，且外形美观，使用更方便。在此基础上，当太阳能电池板41为多晶太阳能电池板时，具有低成本、低功耗、使用寿命长等特点。其中，将太阳能电池板41设置于外壳11的外部，可不占用电子标签本体10的体积，使得电子标签本体10的体积较小。
主控制器
主控制器是电子标签的控制中心，利用各种接口和线路连接整个电子标签的各个部分，通过运行或执行相应的指令，从而使电子标签完成相应的操作，这些操作例如可以是接收外部通信主机(手机、电脑等)发送的信号、对接收到的信号进行解析和处理、之后在显示屏中进行显示等。
主控制器14可以由芯片、集成电路等提供。主控制器14可以集成调制解调处理器，调制解调处理器主要处理无线通信，例如蓝牙或WIFI (Wireless Fidelity，无线保真)。可以理解的是，调制解调处理器也可以不集成在主控制器中。
在本公开的一些实施例中，主控制器14可采用BLE(Bluetooh Low Energy，蓝牙低功耗)SoC(system-on-a-chip，片上系统)芯片(例如，TI(德州仪器)生产的CC2541、CC2543、CC2564等芯片)，其内部CPU(Central Processing Unit，中央处理器)为16位增强型8051单片机，同时包含完整的2.4G射频信号处理单元，运行OSAL(Operating System Abstraction Layer，操作系统抽象层)和BLE 4.0协议栈，因而可同时实现各种应用层任务和蓝牙无线通信。
显示屏12可通过SPI(Serial Peripheral Interface，串行外设接口)与主控制器14连接；传感器13通过I2C(Inter-Integrated Circuit，集成电路总线)与主控制器14连接。
当电子标签在户外环境下应用时，在电子标签受到太阳直射的情况下，环境温度可能会超过电子标签中显示屏所承受的温度范围(例如显示屏的工作温度范围)，而上述电子标签能够通过传感器13对环境温度进行检测，可用来判断环境温度是否超出显示屏12的工作温度范围，一旦处于工作温度范围之外，则停止给显示屏12供电，从而在户外高温环境下，可有效保护电子标签。
除此之外，电子标签还具有更多的和额外的优点，下面结合针对上述电子标签的一些变型，对这些更多的和额外的优点进行描述。
变型一
电子标签还包括设置于壳体11内的微型风扇15。微型风扇15可采用直流3.3V(DC-DC转换器44可将3.7V转为3.3V)供电、功率为0.2W的低功耗微型超薄风扇。微型风扇的规格尺寸从9mm到20mm，外形有方形，圆形等。
在传感器13检测的环境温度高于显示屏12的存储温度范围的最大值的情况下，控制微型风扇15开启对显示屏12降温，直至环境温度降至 低于或等于存储温度范围的最大值的预设温度后，关闭微型风扇15。
应当理解的是，不限于使用微型风扇15来对显示屏12进行降温，而是可以使用类似的散热装置。该散热装置例如可以是使用冷却剂的散热片，或者微通道(Micro Channel)散热器等。
显示屏12的存储温度在A1～A2范围，A1＜A2。例如，当显示屏12实现为电子纸显示屏时，其存储温度范围为-20℃～70℃。
一般而言，显示屏12的存储温度范围应将其工作温度范围包括在内。如前所述，显示屏12的工作温度在C1～C2范围，则A1＜C1，A2＞C2。
此外，对于传感器13而言，其工作温度范围应将显示屏12的存储温度范围包括在内，即传感器13可以在显示屏12的存储温度范围内工作。如前所述，当传感器13的工作温度在B1～B2范围时，则B1＜A1，B2＞A2。
由此可知，显示屏12的工作温度范围C1～C2、显示屏12的存储温度范围A1～A2、以及传感器13的工作温度范围B1～B2三者之间的关系是：B1＜A1＜C1，B2＞A2＞C2。例如，显示屏12的工作温度范围为0～50℃、显示屏12的存储温度范围为-20℃～70℃、温度传感器13的工作温度范围可以为-40℃～125℃。
环境温度(记为D)高于存储温度范围中的最大值，即，D＞A2。
当D＞A2后，微型风扇15开启，直至D降至小于A2的某个预设温度后，关闭微型风扇15。对于该预设温度，可根据实际情况进行设定，在此不做限定。
当电子标签在户外环境下应用时，在电子标签受到太阳直射的情况下，环境温度可能不仅会超过电子标签中显示屏的工作温度范围，而且可能会超过显示屏的存储温度范围，因此即使在电子标签关机不使用的状态下，户外环境的高温也有可能对电子标签造成损害。因此，在本公开一些实施例中，当环境温度高于存储温度范围的最大值后，则进一步开启微型风扇15对显示屏12进行降温，在对显示屏12进行降温的过程中对电子标签也会起到降温作用，从而在户外高温环境下，可有效保护电子标签。
变型二
电子标签还包括设置于壳体11内的开关电路。主控制器14通过该开关电路控制是否向显示屏12或微型风扇15供电。
在本公开一些实施例中，主控制器14控制供电电源40是否向显示屏12供电。用于示范的，主控制器14通过MOSFET(Metal-Oxide-Semiconductor Field-Effect Transistor，金属-氧化物半导体场效应晶体管)开关电路控制供电电源40是否向显示屏12供电。
示例的，MOSFET开关电路，可以为如图7所示的电路，当主控制器40输出高电平至第一节点A1时，晶体管Q1开启，同时MOSFET管Q2打开，供电电源40向第二节点A2输出的供电电压被传输至第三节点A3，之后被提供至显示屏12。当主控制器40输出低电平至第一节点A1时，晶体管Q1、MOSFET管Q2关闭，供电电源40向第二节点A2输出的供电电压无法传输至第三节点A3，供电电源40向显示屏12的供电断开。
MOSFET开关电路可设置于线路板上。
通过由主控制器14来控制是否向显示屏12供电，在需要停止向显示屏12供电时，可快速的反应，从而可最大程度的保护显示屏12。在此基础上，在采用电子纸显示屏的情况下，通过主控制器14的控制，可在电子纸显示屏处于休眠状态下，切断其供电，因此，还可以降低功耗。应当理解的是，在电子纸显示屏处于休眠状态时，只要有供电，电子纸显示屏也是会消耗一定电流(数十微安)的。
在本公开的一些实施例中，主控制器14还控制供电电源40是否向微型风扇15供电。用于示范的，主控制器40通过控制MOSFET开关电路，控制供电电源40是否向微型风扇15供电。该MOSFET开关电路可与上述的MOSFET开关电路相同。
通过由主控制器14来控制是否向微型风扇15供电，在需要停止向微型风扇15供电时，可快速的反应，从而可最大程度的保护微型风扇15，并降低功耗。
变型三
如图8所示，电子标签本体10还包括设置于外壳11内的闪存(Flash Memory)16和收发器17；收发器17，被配置为与通信主机进行通信，以获取通信主机下发的显示信息，并存储至闪存16；闪存16，至少被配置为存储通信主机下发的最新的显示信息；显示屏12，被配置为在主控制器14的控制下显示从闪存16获取的显示信息。
闪存16和收发器17均与主控制器14连接。当收发器17与通信主机(例如手机、电脑等)通信，获取通信主机下发的显示信息后，在主控制器14的控制下，存储至闪存16，并通过显示屏12进行显示。闪存16和收发器17可设置于线路板上。
需要说明的是，当通信主机下发的最新的显示信息存入闪存16时，若闪存16仅被配置为存储通信主机下发的最新的显示信息，则会将在此之前存储的显示信息删除，仅存储通信主机当前下发的最新的显示信息。
闪存是一种非易失性(在断电情况下仍能保持所存储的数据信息)存储器。本公开的实施例中不限于使用闪存，也可以替代为其他的非易失性存储器，例如电子可擦除只读存储器(EEPROM)。闪存16除存储通信主机下发的显示信息外，还可存储电子标签本体10的工作参数、字库数据等。
在主控制器14采用BLE SoC芯片时，在显示屏12通过SPI与主控制器14连接的情况下，闪存16可通过复用SPI与主控制器14连接。
收发器17可以是无线收发器或有线收发器。无线收发器可以为蓝牙收发器、WIFI收发器等。由于蓝牙收发器具有低功耗优点，因此，收发器17选用蓝牙收发器；在此基础上，蓝牙收发器可集成于主控制器14中。通过将蓝牙收发器集成于主控制器14中，使得主控制器14同时实现控制和无线通信功能，可有效降低成本，且可降低线路板的面积。通信主机可以是手机、电脑等具有蓝牙设备的蓝牙主机。
在本公开的一些实施例中，通过收发器17与通信主机进行通信，并通过闪存16存储通信主机下发的显示信息，可方便的对显示屏12显示的 信息进行更新。其中，闪存16至少存储通信主机下发的最新的显示信息，可方便系统重启时恢复。
变型四
在显示屏12为电子纸显示屏的情况下，如图9所示，电子标签本体10还可包括设置于外壳11内的时钟电路18；主控制器14还被配置为控制电子标签本体10进行休眠状态，并在电子标签本体进入休眠状态后，通过时钟电路18进行周期性唤醒，使电子标签本体10处于正常工作状态。
时钟电路18可集成于时钟芯片中。时钟电路18的脉冲输出端可通过I/O(输入/输出接口)与主控制器14连接。时钟电路18可设置于线路板上。
可以理解的是，当电子标签本体10处于正常工作状态时，电子标签本体10的所有器件、电路正常工作。电子标签本体10进行休眠状态，即，电子标签本体10中所有器件、电路均处于低功耗状态。
此外，对于电子纸显示屏而言，只有在刷新时才消耗电流，其它时间都处于低功耗状态，因而，即使主控制器14控制电子标签本体10进入休眠状态，电子纸显示屏仍然会正常显示。
在本公开的一些实施例中，通过使电子标签本体10处于休眠状态，而通过时钟电路18进行周期性唤醒，可在节省功耗的基础上，能进行正常的检测、信息更新等工作。
变型五
在本公开的一些实施例中，电子标签还可以包括激活按键；主控制器14还被配置为在激活按键被按压后，将电子标签本体10从休眠状态唤醒。
激活按键可通过RC低通滤波后与主控制器14的I/O连接。
对于激活按键的设置位置不做限定，设置在用户方便操作的位置即可。示例的，如图10所示，激活按键50可设置于安装座20上。当然，激活按键50也可设置于电子标签本体10的外壳11。
在本公开的一些实施例中，通过设置激活按键50，可根据用户需要随时将电子标签本体10从休眠状态唤醒，可提高用户体验。
变型六
在本公开的一些实施例中，上述电子标签还包括至少一个指示灯；至少一个指示灯与主控制器14连接，被配置为在主控制器14的控制下进行温度报警、电量报警和深度休眠状态提示中的至少一种操作。
如图11所示，至少一个指示灯60可设置于外壳11的侧面，外壳11在对应指示灯60的位置处具有开孔。这样，指示灯60与主控制器14的连接会更容易些。
一个指示灯60可被配置为进行一种状态的指示，也可进行两种及两种以上状态的指示，当进行两种及两种以上状态的指示时，例如既要进行温度报警也要进行电量报警，可通过闪烁频率的不同来进行不同状态的指示。
此外，指示灯并不限于仅进行温度报警、电量报警、深度休眠状态提示，还可以是其他类型的报警、提示等，都属于本公开的保护范围。
在本公开的一些实施例中，通过设置指示灯60，使指示灯60能进行特定的提示，从而便于用户更直观的了解电子标签呈现的某些提示。
变型七
在本公开的一些实施例中，如图4和图5所示，上述电子标签还包括安装座20和可弯曲连接杆30，可弯曲连接杆30的一端与安装座20固定连接，另一端与电子标签本体10固定连接。
基于此结构，可将上述的任一种电子标签应用于汽车，作为车载电子标签，通过显示屏12显示车辆年检信息、环保信息、车辆保险信息等汽车状态相关信息。相对使用传统的贴纸方式粘贴车辆年检信息、环保信息、车辆保险信息等，可避免更换时不易清除干净影响车窗美观的问题，更有利于环保。
当根据本公开一些实施例的电子标签应用于汽车时，可将安装座 20固定于汽车上，并使显示屏12面向汽车前挡风玻璃。其中，可通过调节可弯曲连接杆30，使电子标签本体10与汽车前挡风玻璃平行且有一定距离。将电子标签本体10与汽车前挡风玻璃保持一定距离，可避免电子标签本体10与汽车前挡风玻璃直接接触时，特定条件下可能因高温发生的物理损坏，可尽量减小电子标签本体10的温度。
对于安装座20与汽车的固定方式不做限定，例如可通过超强透明双面胶。
当电子标签中的供电电源包括太阳能电池板41时，可以将太阳能电池板41设置于安装座20上。对于太阳能电池板41在安装座20上的设置位置，应以能接收到光照为准。即，当安装座20固定于汽车前挡风玻璃上时，太阳能电池板41应靠近汽车前挡风玻璃一侧设置。在此基础上，为提供充足的电能，应尽量增大太阳能电池板41的受光面积。
此外，将太阳能电池板41与充电电路42、DC-DC转换器44电连接的导线，也可设置于可弯曲连接杆30内。
由上面的介绍可知，本公开的一些实施例提供了一种电子标签、以及针对此电子标签的多种不同的变型。应当理解的是，针对此电子标签的多种不同变型是可以进行任意组合的，而不是彼此之间相互独立的。例如，除基本的构造外，电子标签还可同时具有微型风扇15、开关电路、闪存16和收发器17、时钟电路18、激活按键、指示灯、安装座20和可弯曲连接杆30等多种零部件，从而具备更多更全的功能。当然，除基本构造外，电子标签也可以仅包括一个或几个其他的零部件，而不必包括上述全部的零部件，例如可以仅包括微信风扇15，或者仅包括微型风扇15、开关电路、闪存16和收发器17。
本公开一些实施例还提供了上述电子标签的运行方法，如图13所示，该电子标签的运行方法包括如下步骤(S21～S40)：
S21、电子标签上电后，对电子标签进行初始化。
在本公开的一些实施例中，当电子标签上电后，需经过一些列初 始化。以上述电子标签包括电子纸显示屏、主控制器14、传感器13、闪存16、时钟电路18，且主控制器14中集成有蓝牙为例，电子标签上电后，首先进行主控制器14内部外设(包括各接口)初始化和BLE协议栈(包括发射功率、广播间隔等)初始化，然后是外部硬件初始化，包括传感器13初始化、时钟电路18初始化、闪存16初始化和电子纸显示屏初始化。
在本公开的一些实施例中，在显示屏12为电子纸显示屏的情况下，上述电子纸显示屏初始化包括：主控制器14检测闪存16中是否存储有显示信息，如果没有，则主控制器14控制供电电源40停止向显示屏供电；否则，主控制器14从闪存16中获取显示信息并写入显示屏12的显存并显示，待显示屏正常显示后主控制器14控制供电电源40停止向显示屏12供电。
主控制器14从闪存16中获取显示信息，并写入显示屏12的显存并显示，可采用分段读取闪存16和写入显存的方法。
由上述对电子纸显示屏初始化的过程可知，不管是否从闪存16中获取到显示信息，电子纸显示屏最终都与供电电源40断开了连接，这样可较大地降低功耗。
S22、在对电子标签进行初始化后，主控制器14在预定时间内等待通信主机的通信请求，若有请求则执行S23，否则停止广播并进入休眠状态。
在本公开的一些实施例中，电子标签上电、并对电子标签进行初始化后，上述电子标签的运行方法还包括：在预定时间内，响应于收发器17与通信主机没有建立连接，主控制器14控制电子标签本体10进入休眠状态；响应于收发器17与通信主机建立连接，且收发器17接收到通信主机下发的显示信息，主控制器14将显示信息存入闪存16并通过显示屏12进行显示，之后，主控制器14控制收发器17断开与通信主机的连接，使电子标签本体10进入休眠状态。
在本公开的一些实施例中，在主控制器14中集成有蓝牙收发器的 情况下，对电子标签进行初始化后，主控制器14可开启例如2秒的广播并等待通信主机(此时为蓝牙主机)的通信请求，如没有蓝牙主机与电子标签连接，则停止广播并进入休眠状态；如果有蓝牙主机与电气标签连接，则按照预定的通信协议，电子标签与通信主机进行信息交互、或通过蓝牙主机与服务器进行信息交互，并在获取蓝牙主机下发的、或在获取由服务器通过蓝牙主机下发的显示信息后，存入闪存16并通过显示屏12进行显示，之后控制收发器17断开与蓝牙主机的连接，使电子标签本体进入休眠状态。
S23、按照预定的通信协议，电子标签与通信主机建立连接，从而与通信主机进行信息交互、或与通信主机具有通信连接的服务器进行信息交互，并在获取通信主机或服务器下发的显示信息后，主控制器14将显示信息存入闪存16并通过显示屏12进行显示，并且主控制器14控制收发器17断开与通信主机的连接，使电子标签本体进入休眠状态。
