具体实施方式
为了使本实用新型的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本实用新型进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本实用新型，并不用于限定本实用新型。基于本实用新型中的实施例，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，都属于本实用新型保护的范围。
本实用新型的实施例提供了一种基于RFID的封条标签及封条标签系统，有效解决了封条标签无法及时通知标签的情况或警报式电子标签成本过高的问题。
请参考图1-图2，图1为本实用新型一实施例提供的基于RFID的封条标签内部结构示意图，图2为本实用新型一实施例提供的基于RFID封条标签整体结构示意图。
本实施例提供的基于RFID的封条标签10，包括插接件100和标签件200，插接件100包括限位部110、握持部120以及金属杆130，限位部110和金属杆130分别位于握持部120的两端，金属杆130的一端收容于握持部120；标签件200包括射频部210以及感应部220，感应部220内部设有第一卡持块221和第二卡持块222，第一卡持块221和第二卡持块222分别与射频部210电连接；第 一卡持块221和第二卡持块222用于在金属杆130插入感应部220后将金属杆130夹持固定、及用于将金属杆130夹持固定后与金属杆130电连接；射频部210包括无线射频单元211，无线射频单元211的两个检测接口分别与所述第一卡持块221和第二卡持块222电连接。
在本实施例中，插接件100用于与标签件200配合使用，在关闭集装箱并锁上时，插接件100的金属杆130穿过集装箱的锁孔，插入标签件200的感应部220。限位部110大于锁孔，以防插接件100穿过锁孔掉落。插接件100的金属杆130与标签件200的感应部220配合连接。金属杆130的横截面大小与感应部220的开口大小一致，能够插入感应部220。当金属杆130插入感应部220，金属杆130与感应部内设的第一卡持块221和第二卡持块222接触，与第一卡持块221和第二卡持块222电连接的无线射频单元211的两个接口闭合。具体的，射频部210的无线射频单元211为无源RFID芯片，其中无线射频单元211还设有天线212，通过天线212接收无线基站发射的电磁波形成电磁场，无线射频单元211在电磁场中通过电磁耦合，将电磁场中的电磁波转化基于RFID的封条标签10的电能。无源RFID芯片获得电能，向无线基站发送基于RFID的封条标签10的状态信息，其中所述基于RFID的封条标签10的状态信息可以通过二进制表示。具体的，基于RFID的封条标签10的状态信息包括基于RFID的封条标签10的ID信息以及状态数据，例如所述基于RFID的封条标签10的状态信息可以表示为011100，011101，其中前四位0111为该基于RFID的封条标签10的ID信息，后两位01或者00则表示当前基于RFID的封条标签10的状态数据。当检测到后两位的状态数据为01时，即两检测接口之间导通，表示基于RFID的封条标签10的处于完好的状态，可知集装箱门并未被打开。当检测到后两位的状态数据为00时，即两检测接口之间断开，表示基于RFID的封条标签10的插接件100和标签件200分离，可获知集装箱门被打开，从而可以及时提醒相关人员做出行动，将损失减到最小。
优选的，如图3为本实用新型实施例中金属杆与感应部连接示意图，金属杆130包括第一金属块131和第二金属块132，第一金属块131的其中一部分收 容于所述第二金属块132内，且第一金属块131远离握持部120一端延伸出第二金属块132。第一卡持块221和第二卡持块222均与第一金属块131电连接。具体的，第二金属块132的内部形成腔部，刚好能够容纳第一金属块131套设在第二金属块132中。同时，第一金属块132延伸出第二金属块132的部分横截面积小于第二金属块132的横截面积。当金属杆130插入感应部220，感应部220中的凸出的第一卡持块221与第二卡持块222夹住第一金属块131延伸出第二金属块132的部分，使插接件100和标签件200固定连接。
请参看图4-图5的另一实施例方案，图4为本实用新型另一实施例中金属杆与感应部连接示意图，图5为图4中插接件爆炸图。第一金属块131与第二金属块132之间设有绝缘部133，以将第一金属块131与第二金属块132隔离。第一金属块131嵌入握持部120一端与所述第二金属块嵌入握持部120一端电连接。第一卡持块221与第一金属块131电连接，第二卡持块222和第二金属块132电连接。第一金属块131位于第二金属块132中的部分由绝缘部133隔离开，同时，两金属块嵌入握持部120的部分电连接。
具体的，握持部120内设有导线121，第一金属块131收容于握持部120内的部分与导线121一端电连接，第二金属块132收容于握持部120内的部分与导线121另一端电连接。第一金属块131与第一卡持块221接触，第二金属块132与第二卡持块222接触，第一金属块131和第二金属块132通过导线电连接第一卡持块221和第二卡持块222，并将握持部120内的导线121的线体部分延伸至限位部110。当限位部110断开与握持部120之间的连接，同时断开导线121，使得第一卡持块221与第二卡持块222之间的通路断开时。例如，集装箱使用所述基于RFID的封条标签封装，当有人企图通过剪刀剪断握持部120与限位部110之间的连接，打开集装箱门，同时也会剪断导线121，使得第一卡持块221与第二卡持块222断开，基于RFID的封条标签的状态数据改变。无线基站检测基于RFID的封条标签10的状态数据，相关工作人员能够根据无线基站检测的状态数据，及时发现集装箱的异常情况。
优选的，握持部120设有台阶式凹槽122，标签件200设有环形锁环230， 环形锁环230的内环壁设有突出的卡扣部(图中未示)，用于与台阶式凹槽122配合卡接。标签件200一侧还设有夹持部240，用于夹持固定所述插接件100。夹持部240为半圆状半包围结构，夹持部240的直径与插接件100的握持部120一样，可卡扣固定握持部120，便于基于RFID的封条标签10整体的装配运输。
优选的，无线射频单元211具体为SL3S1003-1013芯片，请参看图6，图6为本实用新型无线射频单元引脚示意图，该芯片的检测接口分别为引脚6、引脚4，其中引脚6与第一卡持块221电连接，引脚4与第二卡持块222电连接。其中，引脚1、引脚3电连接天线212。该芯片灵敏度极高，用简单的单端口天线设计即可实现较大的读取范围。
在上述实施例中，基于RFID的封条标签10的金属杆130与感应部220之间的电连接的通断，改变无线射频单元状态，通过无线基站检测无线射频单元状态，能够快速有效的提醒集装箱管理人员异常状况发生。
请参看图7，图7为本实用新型实施例中封条标签系统的示意图，封条标签系统包括无线基站20和上述实施例中任意一所述的基于RFID封条标签10。无线基站20为可读取基于RFID的的封条标签10信息的阅读器，通过无线基站20的天线发送无线微波至基于RFID的封条标签10，识别监控封条标签10的状态。同时无线基站20可同时监测多个基于RFID的封条标签10的状态，构成一对多的管理。且封条标签10成本较低，能够大大降低集装箱监控的成本。
以上仅为本实用新型的优选实施例，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
