e、根据所述设置信号， 对所述智能门锁的开锁密码、 开锁密码的剩余开锁 次数或开锁密码的开锁时间段进行设置。
本发明的有益效果：
由于智能门锁通过接收智能开锁设备通过近距离通信方式发送的开锁密 码， 并在判断到所述信号接收电路接收的开锁密码符合预置的开锁条件时， 执 行开锁。 因此实现了通过近距离通信方式实现了智能开锁， 其不同于传统的密 码锁、 指纹锁或物联网锁， 能以筒单、 易行的方式打开智能门锁。
另外， 本发明在智能门锁在接收到正确的开锁密码后， 还判断该开锁密码 对应的剩余开锁次数是否为 0 和 /或当时时间是否在开锁密码对应的开锁时间 段内，只有在判断到剩余开锁次数不为 0和 /或当前时间在开锁密码对应的开锁 时间段内， 才执行开锁。 也就是说， 在本发明中还引入了开锁密码对应的剩余 开锁次数和 /或开锁时间段的概念， 从而丰富了智能门锁的应用。 例如： A周日 会在下午 1点至 1点至 B家中进行家政服务，但 B家在周日下午均没有人在家， 并且不方便将将钥匙预留给 A, 那么采用本发明的智能门锁， 则 B可以预先在 智能门锁中进行如下配置： 开锁密码 " 123789" , 剩余开锁次数： 1次， 开锁时 间段：星期日下午 1点至 2点；完成上述配置后， B可以将该开锁密码提供给 A, 这样， A在周日下午 1点至 1点就可以到 B家中提供家政月良务， 并且 A成功开 锁的次数只有 1次（即 A不能反复地进入 B家）。 附图说明

请参考图 1 , 是本发明的开锁系统的实施例的结构示意图， 该开锁系统包 括： 智能开锁设备 1和智能门锁 2。
其中， 智能开锁设备 1 , 用于通过近距离通信方式向智能门锁 2发送开锁 密码。 近距离通信方式包括： NFC (Near Fie ld Communi cat ion, 近场通信）、 蓝 牙通信或红外通信。 智能开锁设备 1 包括： 智能手机、 平板电脑或者 PDA ( Persona l Digi ta l As s i s tant , 个人数字助理）。
进一步， 智能开锁设备 1可以包括： 处理器 11和信号发射电路 12。 其中 处理器 11 , 可以为 CPU, 用于将接收的开锁密码编码为近场通信信号、 蓝牙信 号或红外信号。其中处理器 11接收的开锁密码可以由用户输入， 或者保存在智 能开锁设备 1的存储器中， 当处理器 11接收到开锁触发指令时， 直接从存储器 中提取开锁密码。 信号发射电路 12可以为： NFC信号发射电路、 蓝牙信号发射 电路或红外信号发射电路， 用于将处理器 11生成的 NFC信号、蓝牙信号或红外 信号发射至智能门锁 2 , 也就是说将开锁密码通过 NFC信号、 蓝牙信号或红外 信号的方式发送至智能门锁 2。
其中， 智能门锁 2包括： 信号接收电路 21、 中央处理器 22和执行部件 23。 信号接收电路 21 , 用于接收智能开锁设备 1 (例如： 智能开锁设备 1中的信号 发射电路 12 )通过近距离通信方式发送的开锁密码。近距离通信方式包括： NFC、 蓝牙通信或红外通信， 信号接收电路 21包括： NFC信号接收电路、 蓝牙信号接 收电路或红外信号接收电路。
中央处理器 22 , 用于判断信号接收电路 21接收的开锁密码是否符合开锁 条件，且在判断到信号接收电路 21接收的开锁密码符合开锁条件时，将开锁指 令输出至执行部件 23 , 若判断到信号接收电路 21接收的开锁密码不符合开锁 条件， 则拒绝智能开锁设备 1的开锁请求， 拒绝开锁请求的执行方式可以是： 不做任何反应、 向智能开锁设备 1返回拒绝响应， 等等。 其中， 开锁条件预先 配置在智能门锁 2中， 例如： 存储在智能门锁 2中的存储器中， 中央处理器 22 中得到信号接收电路 21接收到开锁密码后，从存储器中提取开锁条件， 并将开 锁密码与提取的开锁条件进行比较，以判断信号接收电路 21接收的开锁密码是 否符合开锁条件。 开锁条件一般包括： 信号接收电路 21接收的开锁密码应为： 预置的唯一开 锁密码， 或者： 信号接收电路 21接收的开锁密码应为： 预置的多个开锁密码之 一。 其中， 预置多个开锁密码的目的是： 可以将不同的开锁密码分发给不同的 使用者使用， 以利于对使用者进行管理。
在上述基础上， 开锁条件进一步包括： 当信号接收电路 21接收的开锁密码 为： 预置的唯一开锁密码或者为： 预置的多个开锁密码之一时， 信号接收电路 21接收的开锁密码对应的剩余开锁次数不为 0, 或者， 当前时间在信号接收电 路 21接收的开锁密码对应的开锁时间段内， 或者， 信号接收电路 21接收的开 锁密码对应的剩余开锁次数不为 0且当前时间在信号接收电路 21接收的开锁密 码对应的开锁时间段内。
上述开锁条件可以用表的形式保存， 例如表一至表三：

密码 剩余开锁次数 开锁时间段
1254*89 无限次 不限
5789¾125 14次 每天的 12: 00—13: 00, 18: 00 - 19: 00
335489 1次 周日的 13: 00 - 14： 00 对于表一和三中的剩余开锁次数， 除了无限次外， 其它的当记录到相应的 密码成功开锁一次后， 将剩余次数减一， 直到为 0, 并记录在表一中， 例如： 当密码 335489被用于成功开锁一次后，其对应的剩余开锁次数变为由 1变为 0。
进一步，请参考图 3,是图 1的中央处理器 22的一实施方式的结构示意图。 该中央处理器 22可以由 CPU或单片机等实现， 其包括： 第一比较器 221、 第二 比较器 111和输出接口 223。
第一比较器 221 , 用于判断信号接收电路 21接收的开锁密码是否为： 预置 的唯一开锁密码或者是否为： 预置的多个开锁密码之一。 举例来言， 预置的开锁密码为： {1254*89， 5789 25， 335489}，当信号接收 电路 21接收的开锁密码为： 1254*89或 5789¾)125或 335489时， 则第一比较器 221将输出是的判断结果。
第二比较器 222 , 用于当第一比较器 221判断到信号接收电路 21接收的开 锁密码为： 预置的唯一开锁密码或者为： 预置的多个开锁密码之一时， 继续判 断信号接收电路 21接收的开锁密码对应的剩余开锁次数是否为 0、 和 /或当前 时间是否在信号接收电路 21接收的开锁密码对应的开锁时间段内。
举例来言， 开锁条件如表三所示， 信号接收电路 21 接收的开锁密码为： 335489。 则第二比较器 222只在开锁密码 "335489" 在周日的 13: 00 - 14： 00 间第一次使用时， 才输出是的判断结果。
上述中引入剩余开锁次数和 /或开锁时间段的概念的好处在于，可以针对某 些特殊使用情况而限制开门次数和 /或开锁时间，如对每周一次的家政服务， 当 由于住宅主人不在家而导致家政服务因不能开门而未被服务时， 可将某个开锁 密码设置为每周开锁一次， 提供给家政服务人员， 即可避免上述问题。
输出接口 223 , 用于当第二比较器 222判断到信号接收电路 21接收的开锁 密码对应的剩余开锁次数不为 0和 /或当前时间在信号接收电路 21接收的开锁 密码对应的开锁时间段内时， 输出开锁指令。 否则， 拒绝开锁请求。 执行部件 23 , 用于接收中央处理器 22的开锁指令， 根据开锁指令执行开 锁操作。具体地， 如图 3所示，执行部件 23包括： 锁舌驱动电路 231、 电机 232 和带有齿条的金属锁舌 233。 其中， 电机 232 包括： 转轴和安装在转轴上的齿 轮， 该齿轮与带有齿条的金属锁舌 233啮合。 锁舌驱动电路 231 , 用于当接收 到中央处理器 22的开锁指令时， 控制电机 232正向转动， 带动齿条正转， 从而 控制金属锁舌 233完成开锁动作。 补充说明的是， 智能门锁 1的关锁过程， 可 以采用与开锁过程类似的方式， 但是其过程可以更筒单， 例如： 由智能开锁设 备 2向智能门锁 1发送关锁密码，当中央处理器 22验证关锁密码与预置的关锁 密码相同时， 则向锁舌驱动电路 231发送关锁指令， 由锁舌驱动电路 231控制 电机 232反向转动， 带动齿条反转， 从而控制金属锁舌 233完成关锁动作。
本实施全由于智能门锁通过接收智能开锁设备通过近距离通信方式发送的 开锁密码， 并在判断到所述信号接收电路接收的开锁密码符合开锁条件时， 才 执行开锁。 因此实现了通过近距离通信方式实现智能门锁的打开， 其不同于传 统的密码锁、 指纹锁或物联网锁， 能够以筒单、 易行的方式实现智能门锁的打 开。
本发明由于在智能门锁在接收到正确的开锁密码后， 还判断该开锁密码对 应的剩余开锁次数是否为 0 和 /或当时时间是否在开锁密码对应的开锁时间段 内，只有在判断到剩余开锁次数不为 0和 /或当前时间在开锁密码对应的开锁时 间段内， 才执行开锁。 也就是说， 在本发明中还引入了开锁密码对应的剩余开 锁次数和 /或开锁时间段的概念，从而丰富了智能门锁的应用，适用于许多需要 对开锁次数和开锁时间进行控制的场合。
请参考图 4 , 是图 1中智能门锁部分的又一实施例的结构示意图。
图 4实施例与图 1实施例相比， 该智能门锁 2还包括： 后备电源 25和 /或 串口通讯电路 24。 其中， 后备电源 25与信号接收电路 21、 中央处理器 22和执 行部件 23 (主要是： 锁舌驱动电路 231和电机 232 ) 电连接， 用于在停电时保 证智能门锁 1的正常开锁或关锁操作。后备电源 25可以采用可充电电池组， 其 好处在于： 保障电能损耗后能得到补充。 串口通讯电路 24 , 用于接收智能开锁设备 1的用于设置开锁密码、 关锁密 码、剩余开锁次数或开锁时间段的设置信号。其中串口通讯电路 24仅能与智能 开锁设备 1有线连接， 且当智能门锁 2安装在诸如防盗门等上后， 串口通讯电 路 24位于房内一侧， 以此保证智能门锁 2的开锁密码、 关锁密码、 剩余开锁次 数或开锁时间段不会被恶意重置。 当串口通讯电路 24 接收到智能开锁设备 1 的用于设置开锁密码、 关锁密码、 剩余开锁次数或开锁时间段的设置信号后， 中央处理器 22 , 用于根据串口通讯电路 24接收的设置信号， 设置智能门锁 2 的开锁密码、 关锁密码、 剩余开锁次数或开锁时间段。
请参考图 5 , 是本发明的开锁方法的第一实施例的流程示意图。 其中， 该 方法的执行主体可以是上述中涉及的智能门锁 2 , 该方法包括如下步骤：
步骤 Sl l、 接收智能开锁设备通过近距离通信方式发送的开锁密码。
其中， 步骤 S11的执行主体可以是图 1中的信号接收电路 21。 近距离通信 方式包括： NFC、 蓝牙通信或红外通信。 步骤 S11接收的开锁密码可以是由图 1 中的智能开锁设备 1发送。
步骤 S12、 当判断到所述接收的开锁密码符合预置的开锁条件时， 输出开 锁指令。
其中， 步骤 S12的执行主体可以是 1中的中央处理器 22。 如图 6所示， 步 骤 S12可以进一步地包括：
步骤 S121、 判断步骤 S11接收的开锁密码是否为预置的唯一开锁密码， 或 者是否为预置的多个开锁密码之一。
步骤 S122、 当步骤 S121判断到步骤 S11接收的开锁密码为预置的唯一开 锁密码或者为预置的多个开锁密码之一时， 继续判断步骤 S11接收的开锁密码 对应的剩余开锁次数是否为 0和 /或当前时间是否在步骤 S11接收的开锁密码对 应的开锁时间段内。
步骤 S123、 当步骤 S122判断到步骤 S11接收的开锁密码对应的剩余开锁 次数不为 0和 /或当前时间在步骤 S 11接收的开锁密码对应的开锁时间段内时， 输出开锁指令。 上述中步骤 S121 -步骤 S123的执行主体可以分别是图 2中的第一比较器 221、 第二比较器 222和输出接口 223。
步骤 S13、 根据所述输出的开锁指令， 执行开锁。
其中， 步骤 S13 的执行主体可以是上述中的执行部件 23, 且执行部件 23 具有图 3所示的结构。
请参考图 7 , 是本发明的开锁方法的第二实施例的流程示意图。 图 7 实施 例与图 5实施例的不同之处在于， 还包括：
步骤 S14、 接收智能开锁设备的用于设置开锁密码、 开锁密码的剩余开锁 次数或开锁密码的开锁时间段的设置信号。
步骤 S15、 根据所述设置信号， 对所述智能门锁的开锁密码、 开锁密码的 剩余开锁次数或开锁密码的开锁时间段进行设置。
其中， 步骤 S14 -步骤 S15的执行主体可以分别是图 4中的串口通讯电路 24和中央处理器 22。 另外， 步骤 S14 -步骤 S15并不一定都在步骤 S13之后， 其也可以是在步骤 S11之前， 这些本实施例并不进行限定。
需要说明的是，由于图 1 - 4中的结构实施例已对相应的方法细节和流程进 行了说明， 因此并不详细叙述上述流程。
请参考图 8 , 是本发明的开关锁方法的一种具体实施例的流程示意图。 在 该实施例中， 智能开锁设备为手机， 智能开锁设备和智能门锁之间采用蓝牙通 信。 其包括如下步骤：
步骤 S20、 手机向智能门锁发送蓝牙开锁或关锁命令。
步骤 S21、 智能门锁接收手机发送的蓝牙开锁或关锁命令。
步骤 S22、 智能门锁判断接收的是开锁还是关锁命令， 若是开锁命令， 则 执行步骤 S23 , 若是关锁命令则执行步骤 S28。 此处， 开锁命令中携带有开锁密 码， 关锁命令中携带有关锁密码， 步骤 S22还需要判断开锁密码和关锁密码是 否正确， 在正确的前提下才执行后续的流程。
步骤 S23、 判断开锁命令中的开锁密码的剩余开锁次数是否为 0, 若为 0, 则直接结束处理流程， 若不为 0, 则执行步骤 S24。 步骤 S24、 判断当前时间是否在开锁密码对应的开锁时间段内， 若否则直 接结束， 若是则执行步骤 S25。
步骤 S25、 开锁密码对应的剩余开锁次数减 1。 需要说明的是， 若开锁密码 对应的剩余开锁次数为无限次， 则减 1后仍为无限次。
步骤 S26 , 生成开锁命令， 并发送至锁舌驱动电路。
步骤 S27、 锁舌驱动电路驱动电机正向转动开锁后， 结束。
步骤 28、 将关锁命令发送至锁舌驱动电路。
步骤 S29、 锁舌驱动电路驱动电机反向转动关锁后， 结束。
最后说明的是， 以上实施例仅用以说明本发明的技术方案而非限制， 尽管 参照较佳实施例对本发明进行了详细说明， 本领域的普通技术人员应当理解， 可以对本发明的技术方案进行修改或者等同替换， 而不脱离本发明技术方案的 宗旨和范围， 其均应涵盖在本发明的权利要求范围当中。
