具体实施方式
为了使本技术领域的人员更好地理解本申请方案,下面将结合本申请实施例中的附图,对本申请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申请一部分的实施例,而不是全部的实施例。基于本申请中的实施例,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,都应当属于本申请保护的范围。
需要说明的是,本申请的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本申请中,术语“上”、“下”、“左”、“右”、“前”、“后”、“顶”、“底”、“内”、“外”、“中”、“竖直”、“水平”、“横向”、“纵向”等指示的方位或位置关系为基于附图所示的方位或位置关系。这些术语主要是为了更好地描述本实用新型及其实施例,并非用于限定所指示的装置、元件或组成部分必须具有特定方位,或以特定方位进行构造和操作。
并且,上述部分术语除了可以用于表示方位或位置关系以外,还可能用于表示其他含义,例如术语“上”在某些情况下也可能用于表示某种依附关系或连接关系。对于本领域普通技术人员而言,可以根据具体情况理解这些术语在本实用新型中的具体含义。
此外,术语“安装”、“设置”、“设有”、“连接”、“相连”、“套接”应做广义理解。例如,可以是固定连接,可拆卸连接,或整体式构造;可以是机械连接,或电连接;可以是直接相连,或者是通过中间媒介间接相连,又或者是两个装置、元件或组成部分之间内部的连通。对于本领域普通技术人员而言,可以根据具体情况理解上述术语在本实用新型中的具体含义。
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
如图1-图6所示的车牌电子标签,可以包括金属层1和介质层2,还包括设置在金属层上的芯片3;金属层1至少包括位于车牌电子标签顶层的振子天线11、中间层的导通金属带线12和位于底层的金属底板13;介质层2至少包括第一介质层21和第二介质层22。
金属底板13的上表面与第一介质层21的下表面相邻,第一介质层21上表面与导通金属带线12的下表面相邻,导通金属带线12的上表面与第二介质层22的下表面相邻,第二介质层22的上表面与振子天线11的下表面相邻;振子天线11和导通金属带线12之间具有连接关系。
本申请中是充分利用车牌的金属部分,将车牌耦合为天线的一部分,视为GND。另外,导通金属带线的宽度可以调节,导通金属带线的宽度的调节可以改变天线的输入阻抗,从而调整车牌电子标签的频宽和频率。
在一种优选的实现方式中,第二介质层22与第一介质层21之间形成一个阶梯状的槽面4,如图1所示,通过槽面4可以将车牌电子标签黏贴在车牌上。可以理解的是,槽面4上覆盖一层VHB胶,也可以是其他具有较强粘合性的胶。
在一种优选的实现方式中,导通金属带线12包括位于槽面4上的耦合天线121和埋于第一介质层21和第二介质层22之间的微带线122。进一步的,芯片3位于耦合天线121上。可以理解的是,由于槽面4上的VHB胶5具有较大的粘合性,当标签粘在车牌上后,再拆下来,很可能将槽面4上的芯片3一起撕下来。从而一拆就损坏了标签。
可以理解的是,振子天线11和槽面4上的耦合天线121裸露在车牌标签的表面,为了防止其生锈或者被损坏,可以在振子天线11和耦合天线121的表面刷一层保护漆,但设置在耦合天线121上的芯片3的表面不需要刷漆。
具体实现中,振子天线11与埋在介质层2中的微带线122具有连接关系,二者的连接关系可以通过介质层2上设置的通孔23实现。可选的,通孔23的大小可以根据微带线122或振子天线11的宽度来定,也可以不考虑二者的宽度,将介质层2全部导通。
在一种可选的实现方式中,标签的下表面即金属底板13上可以安装泡棉胶6,可以将标签固定在汽车安装车牌的后板上。
需要说明的是,当标签安装在车牌后板上时,为实现车牌一拆即毁,可以在槽面4上开一防拆割口41,当标签被拆除时,会从防拆割口41处断开,从而损坏标签。优选的,该防拆割口41可以是V型割槽。可以理解的是,所开的V型割槽位于介质层2上,不会对金属层1产生影响(即不会割断金属层)。具体实现中,所开的V型割槽位于两阶梯连接处的槽面4上。需要说明的是,在标签上开有防拆割口41的时,标签的下表面即金属底板13上要覆盖VHB胶5。
本申请实施例中,通过在车牌上做修改,设计一种全新的黏贴在车牌上的电子标签,利用车牌的金属部分将车牌耦合为天线的一部分视为GND,实现了RFID的远距离读取,增加了对车辆管理的便利性,车牌上安装此类RFID标签 后便不能取下来,一拆即损坏芯片,有效的遏制了挡牌号、套牌等非法行为的发生。
本申请的实施例还提供了一种车辆管理装置,装置包括金属车牌以及上述图1至图6中所记载的车牌电子标签,如图1中所示,车牌电子标签通过槽面上与金属车牌的背面相连,具体的是通过槽面上的胶相连。该车辆管理装置可以通过车牌电子标签发送通过金属车牌作为天线向电子标签读写器发送电磁波,并将车牌电子标签对应的车辆信息传送给电子标签读写器,以通过电子标签读写器获取车辆信息并对车辆进行管理。
本申请的实施例,还提供了一种车辆管理方法,是应用上述实施例中的车辆管理装置对车辆进行管理,所述方法包括:在有效距离范围内,所述车牌电子标签通过所述金属车牌作为天线向电子标签读写器发送电磁波,并将所述车牌电子标签对应的车辆信息传送给所述电子标签读写器,以通过所述电子标签读写器获取所述车辆信息并对车辆进行管理。所述有效距离范围为15m。相比于现有的RFID标签实现了远距离读取。具体的该有效距离可以通过NXP UCode8芯片测试得到。
以上仅是本发明的优选实施方式,并非对本发明作任何形式上的限制。应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
另外需要说明的是,在上述具体实施方式中所描述的各个具体技术特征,在不矛盾的情况下,可以通过任何合适的方式进行组合。为了避免不必要的重复,本发明实施例对各种可能的组合方式不再另行说明。
此外,本发明实施例的各种不同的实施方式之间也可以进行任意组合,只要其不违背本发明实施例的思想,其同样应当视为本发明实施例所公开的内容。
