Description

无源驱动系统及无源锁 技术领域
本发明涉及一种无源驱动系统及无源锁。
背景技术
高速发展的当下，高新技术的不断更新，各种基于NFC(Near Field Communication,NFC)近场通讯技术的产品，广泛的应用于门禁、移动支付、航空包裹和行李识别、邮件分选、商品流通控制以及电子防伪等领域。尤其在电子锁类的产品，倡导着无钥匙带来的高效便捷使用体验，已经为广大消费群体所推崇。
目前市面上应用NFC技术的产品，譬如NFC锁具，绝大部分都是以电池供电为主，这不仅是和主流的环保倡导理念大相径庭，也额外增加了产品的体积、重量、成本，以及用户的使用成本。传统的NFC锁，仅是靠读取卡片的UID为识别依据，密码是明文传输，存在着易被破解复制的技术弊端。因此对于现有NFC开锁方式，普遍存在功率不足，天线过大，制约无源锁的广泛推广。
发明内容
相对传统的需要电池或电源供应的电子锁电路，本发明采用便捷可靠的多介质无源开锁技术，通过改善功率传输方式，深度优化天线匹配，使其功率利用效率最大化；并且使用新型加密技术，每一个认证都加密传输。
本发明所要解决的技术问题在于提供一种无源驱动系统，其中，包括：
能量转换单元，接收供能装置输出的能量后将所述能量转化为电能；
控制单元，接收所述电能并用以驱动一电动单元；
认证单元，与所述供能装置进行安全认证；
其中，当所述供能装置通过安全认证后，所述控制单元输出驱动信号驱动所述电动单元。
上述的无源驱动系统，其中，所述控制单元包括：
存储模块，存储所述电能；
检测模块，检测所述存储模块的电能存储量，当所述电能存储量达到一阈值时，输出第一信号；
主控模块，根据所述第一信号设置所述无源驱动系统进入准备驱动状态。
上述的无源驱动系统，其中，进入所述准备驱动状态后，所述电动单元根据所述驱动信号工作。
上述的无源驱动系统，其中，所述认证单元为电子标签。
上述的无源驱动系统，其中，所述认证单元为红外线收发装置。
本发明还提供一种无源锁，其中，包括：
上述中任一项所述的无源驱动系统；
电动单元；
其中，所述无源驱动系统接收并存储供能装置输出的能量，当所述供能装置通过安全认证后，所述无源驱动系统驱动所述电动单元解锁或闭锁。
本发明针对于现有技术其功效在于：
(1)基于多种无线传输认证方式，加密程度高，可以根据不同应用场合，选择不受环境制约的认证方式(包括红外线，125K,13.56MHZ,900MHZ)；
(2)无线认证和驱动电路相互独立，工作效率高，串扰小；
(3)无需额外的电池或电源供电，最大程度的降低产品体积及制造维护成本；
(4)本发明可以通过红外线，125K、13.56MHZ、900MHZ无线认证方式实现无源锁的开锁方法；
(5)本发明将能量传输和认证通道分开，独立工作，同时改进认证方式，将无源锁小型化，特殊应用场合采用红外线认证方式，抗干扰，抗屏蔽效果明显
附图说明
图1为本发明无源锁的结构示意图。
具体实施方式
下面结合附图与具体实施例对本发明作进一步详细描述：本实施例在以本发明技术方案为前提下进行实施，给出了实施方式和操作过程，但本发明的保 护范围不限于下述的实施例。
请参照图1，图1为本发明无源锁的结构示意图。如图1所示，本发明的无源锁包括：无源驱动系统1及电动单元2；所述无源驱动系统1接收并存储供能装置3输出的能量，当所述供能装置3通过安全认证后，所述无源驱动系统驱1动所述电动单元2解锁或闭锁。
进一步地，无源驱动系统1包括：能量转换单元11、控制单元12及认证单元13；能量转换单元11接收供能装置3输出的能量后将所述能量转化为电能；控制单元12接收电能并用以驱动电动单元2；认证单元13与所述供能装置3进行安全认证；其中，当所述供能装置3通过安全认证后，所述控制单元12输出驱动信号驱动所述电动单元2。
再进一步地，所述控制单元12包括：存储模块121、检测模块122及主控模块123，存储模块121存储所述电能；检测模块122检测所述存储模块121的电能存储量，当所述电能存储量达到一阈值时，输出第一信号；主控模块123根据所述第一信号设置所述无源驱动系统进入准备驱动状态并输出驱动信号，进入所述准备驱动状态后，所述电动单元2根据所述驱动信号工作。
其中，在本实施例中所述认证单元13为电子标签，电子标签内设有能量转换单元11，能量转换单元11为功率天线电性连接于存储模块121，存储模块121电性连接于主控模块123及检测模块122，主控模块123电性连接于电动单元2，通过功率天线将供能装置3输出的的能量后将所述能量转化为直流电能，其中功率发送天线可以根据工作场合，锁体结构等要求选择宽范围的100KHZ--50MHZ工作频率的正弦波，脉冲波等射频场，使收发能量效率最大化，接收前段将载波转换为直流电能提供给控制单元12及电动单元2使用。即功率天线的射频场，经高速整流，滤波，稳压后，将输出稳定的直流电源，供给控制单元12及电动单元2使用。此电路不作解调信号，仅作电源使用。同时所述供能装置3通过电子标签内的认证信号传输无线将认证信号传到主控模块123，所述主控模块123控制电动单元2进行解锁或闭锁操作；采用电子标签，其感应方式包括125k、13.56MHZ、960MHZ，因为控制单元12由供能装置3传输能量，故认证单元13不需要功率传输，就可以与供能装置3做双向通信。在本实施例中，电动单元2为电机，但本发明并不以此为限。由此本发明解决电子锁电池供电带来的不便，具有可靠性、快速性和方便性。
在本发明的另一实施例中，所述认证单元13为红外线收发装置，所述无源驱动系统进入准备驱动状态，当具备加密协议的供能装置3(红外线，125K,13.56MHZ,900MHZ标签)靠近红外线收发装置(红外线，125K,13.56MHZ,900MHZ标签)时，将以点对点的模式，建立起交换认证数据的通道。需要说明的红外收发方式特别适合远距离，高危，应用场合，具有抗干扰能力强，控制距离远，无需供电。
综上所述，本发明硬件设备安全可靠，成本低廉，适于广泛应用，可以普及到一般小型化的无源锁应用；不受认证天线的制约；除了一般锁具应用，还可以开启大功率锁头；其中红外线方式适合较远距离开锁，且抗电磁干扰强。
虽然本发明已以上述实施例揭露如上，然其并非用以限定本发明，在本发明所属技术领域中的相关技术人员，在不脱离本发明的精神和范围内，当可作各种的更动与润饰，因此本发明的保护范围当视所附的权利要求书所界定的保护范围为准。
