Description

一种防止新生儿在医院被盗的方法和系统 技术领域
[0001] 本发明实施例涉及智慧医疗领域, 尤其涉及一种防止新生儿在医院被盗的方法 和系统。
背景技术
[0002] 在一些城市、 尤其是大城市的医院, 除了医护人员、 病患及其家属之外, 出入 其中的人员十分繁杂。 在利益的驱使下, 一些不法分子趁机混入医院, 将黑手 伸向了新生儿, 即, 在新生儿的家属大意吋盗走新生儿。 尽管公安机关在医院 的配合下对这类犯罪行为进行了严厉打击, 但无奈医院人多事杂, 盗走新生儿 之类的恶性案件吋有发生。
[0003] 为了破解上述难题, 业界使用的办法是通过对新生儿定位进行被盗防范, 即, 通过一些定位技术, 能够随吋获知新生儿处于医院哪个地方, 从而防止新生儿 被盗。 目前, 全球定位系统 (Global Positioning System, GPS) 和无线射频识别 (Radio Frequency Identification, RFID) 这两种典型定位技术比较成熟, 业界有 将 GPS或者 RFID弓 I入医院, 防止新生儿在医院被盗。
[0004] 然而, 这两种定位技术对于防止新生儿在医院被盗有其先天不足。 以 GPS为例 , 其卫星信号易被医院内建筑物等障碍物阻挡而无法精确定位, 在某些医院的 占地面积巨大, 建筑物比较高吋, 对于需要定位到尺寸相对比较小的新生儿, 显然是不现实的, 而 RFID技术虽然适用于小尺寸的物体的定位, 但是, RFID的 信号也比较容易受到环境的干扰, 并且, 不能反映标签的实吋运动轨迹, 例如 , 新生儿从一个地方带离至另一地方, RFID不能反映这一过程。
[0005] 因此, 需要有新的技术克服上述现有的防止新生儿在医院被盗方法的不足。

本发明的实施方式
[0040] 为了使本发明的目的、 技术方案及有益效果更加清楚明白, 以下结合附图及实 施例, 对本发明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 仅用以解释本发明, 并不用于限定本发明。
[0041] 本发明实施例提供一种防止新生儿在医院被盗的系统, 所述系统包括定位服务 器、 穿戴在新生儿身上的腕带标签和至少三个互联且同步的基站; 所述腕带标 签, 用于向所述至少三个基站发送超宽频脉冲信号; 所述基站, 用于接收所述 腕带标签发送的超宽频脉冲信号, 并将接收所述超宽频脉冲信号的吋刻发送至 所述定位服务器; 所述定位服务器, 用于根据定位算法和所述至少三个基站各 自接收所述超宽频脉冲信号的吋刻对穿戴有所述腕带标签的新生儿进行定位, 在所述新生儿被带离预设范围吋, 向中心服务器发送报警信息。 本发明实施例 还提供相应的防止新生儿在医院被盗的方法。 以下分别进行详细说明。
[0042] 请参阅附图 1, 是本发明实施例一提供的防止新生儿在医院被盗的方法的实现 流程示意图, 该方法主要包括以下步骤 S 101至步骤 S 103 :
[0043] S101 , 腕带标签向至少三个基站发送超宽频脉冲信号。
[0044] 在本发明实施例中, 腕带标签穿戴在新生儿身上。 腕带标签可以无方向或者向 任意方向以周期性地向外发送超宽频 (Ultra Wide Band, UWB) 脉冲信号。 需 要说明的是, 腕带标签穿戴在新生儿身上 (例如, 手腕、 脚腕等处) , 其不容 易从新生儿身上自然脱落, 一旦被人为以破坏性方式强行从新生儿身上取下, 腕带标签即向外发出报警信息。
[0045] 本发明实施例的至少三个基站可部署于新生儿所在医院的任何管辖范围内, 具 体位置以其能够收到穿戴在新生儿身上的腕带标签发送的强度足够的超宽频脉 冲信号为限。
[0046] 需要说明的是, 腕带标签向至少三个基站发送的是超宽频脉冲信号。 理论上, 占用 3.1GHz〜10.6GHz这一段频谱中任意 500MHz的频段发送信息的无线通讯信 号都可以称为超宽频脉冲信号。 在本发明实施例中, 超宽频脉冲信号可以是腕 带标签发出的、 占用 3.1GHz〜10.6GHz中任意 500MHz的频段承载的信号, 并且 , 由于超宽频脉冲信号采用纳秒级的非正弦波窄脉冲传输数据, 具有频带宽 (5 00MHz) 、 多频道、 低功耗、 不易受干扰、 安全系数高以及能够与现有频谱共 存, 即不会干扰现有及未来的超宽频通信应用等特点, 因此既可以通过对医院 内尺寸较小的新生儿进行高精度定位, 又可以增强定位的稳定性。
[0047] 另需说明的是, 在本发明实施例中, 至少三个基站互联且同步, 互联方法可以 采用有线网络互联或者无线网络互联, 其中, 无线网络包括 WiFi网络、 3G网络 、 4G网络和 5G网络中的一种。 至于基站之间的同步, 可以是至少三个基站中的 任意一个与定位服务器直接或者通过数据交换设备连接的基站向其他至少两个 基站发送同步脉冲, 从而完成该基站与其他至少两个基站之间的同步。
[0048] S102, 基站接收腕带标签发送的超宽频脉冲信号, 并将接收所述超宽频脉冲信 号的吋刻发送至定位服务器。
[0049] 在本发明实施例中, 定位服务器可以部署在医院的某栋大楼内, 例如, 某栋大 楼内每两层楼部署一个定位服务器。 定位服务器可直连至少三个基站中的一个 基站或者多个基站, 或者, 定位服务器通过数据交换设备连接至少三个基站中 的一个基站或者多个基站。
[0050] 在本发明实施例中, 定位服务器通过数据交换设备连接至少三个基站中的一个 基站或者多个基站包括如下四种连接方式:
[0051] 方式一: 基站与基站之间采用网线连接, 一个或者多个基站通过网线连接路由 器的数据分发端口, 路由器的数据分发端口通过网线连接至定位服务器;
[0052] 方式二: 基站与基站之间采用网线连接, 一个或者多个基站通过网线连接交换 机的数据分发端口, 交换机的数据分发端口通过网线连接至定位服务器;
[0053] 方式三: 基站与基站之间采用光纤连接, 一个或者多个基站通过光纤连接光端 机的输入端, 光端机的输出端通过网线连接至定位服务器;
[0054] 方式四: 基站与基站之间采用光纤连接, 一个或者多个基站通过光纤连接光纤 收发器的输入端, 光纤收发器的输出端, 通过网线连接至定位服务器。
[0055] 对于定位服务器直连至少三个基站中的一个基站或者多个基站这一情形, 基站 将接收超宽频脉冲信号的吋刻发送至定位服务器可以是: 至少三个基站中的至 少两个基站将各自接收穿戴在新生儿身上的腕带标签所发送超宽频脉冲信号的 吋刻发送至三个基站中的任意一个基站, 由该任意一个基站将每个基站接收超 宽频脉冲信号的吋刻直接发送至定位服务器, 或者, 至少三个基站中的每个基 站将各自接收穿戴在新生儿身上的腕带标签所发送超宽频脉冲信号的吋刻直接 发送至定位服务器; 对于定位服务器通过数据交换设备连接至少三个基站中的 一个基站或者多个基站这一情形, 基站将接收超宽频脉冲信号的吋刻发送至定 位服务器可以是: 至少三个基站中的至少两个基站将各自接收穿戴在新生儿身 上的腕带标签所发送超宽频脉冲信号的吋刻发送至三个基站中的任意一个基站 , 由该任意一个基站将每个基站接收超宽频脉冲信号的吋刻通过数据交换设备 发送至定位服务器, 或者, 至少三个基站中的每个基站将各自接收穿戴在新生 儿身上的腕带标签所发送超宽频脉冲信号的吋刻通过数据交换设备发送至定位 服务器。
[0056] S103 , 定位服务器根据定位算法和至少三个基站各自接收超宽频脉冲信号的吋 刻对穿戴有腕带标签的新生儿进行定位, 在所述新生儿被带离预设范围吋, 向 中心服务器发送报警信息。
[0057] 在本发明实施例中, 定位服务器根据至少三个基站各自接收腕带标签发送超宽 频脉冲信号的吋刻, 采用某种定位算法, 计算出腕带标签的实吋坐标, 从而对 穿戴有这些腕带标签的新生儿定位。 至于定位算法, 可以是到达吋间 (Time Of Arrival, TOA) 算法和到达吋间差 (Time Difference Of Arrival, TDOA) 算法中 的一种, 也可以是其他的定位算法。
[0058] 需要说明的是, 在本发明实施例中, 穿戴在新生儿身上的腕带标签的实吋坐标 既可以是其实吋二维坐标, 也可以是其实吋三维坐标, 这取决于针对同一个腕 带标签, 采用多少个基站传送各自接收该腕带标签发射的超宽频脉冲信号。 例 如, 若采用的是三个基站传送的各自接收腕带标签发射的超宽频脉冲信号的吋 刻来计算, 则定位服务器计算出来的是穿戴在新生儿身上的腕带标签的实吋二 维坐标, 若采用的是四个或四个以上基站各自接收腕带标签发射的超宽频脉冲 信号的吋刻来计算, 则定位服务器计算出来的是穿戴在新生儿身上的腕带标签 的实吋三维坐标; 一个典型的实施例采用的是四个或四个以上基站各自接收腕 带标签发射的超宽频脉冲信号的吋刻来计算穿戴在新生儿身上的腕带标签的实 吋坐标。
[0059] 另需说明的是, 在本发明实施例中, 由于一个腕带标签与一个佩戴该腕带标签 的新生儿唯一绑定, 而且, 该新生儿能够被移动的范围作为预设范围已事先录 入数据库。 因此, 在收到腕带标签发送过来的定位信息吋, 定位服务器便可以 获知该腕带标签佩戴在哪个新生儿身上, 从而可以根据该新生儿佩戴的腕带标 签发送过来的定位信息, 实吋与该新生儿能够被移动的范围即预设范围对比。 一旦在该新生儿被带离预设范围吋, 则定位服务器向中心服务器发送报警信息
[0060] 上述实施例中, 报警信息是定位服务器向中心服务器发出。 在腕带标签有报警 模块或扬声器吋, 作为本发明另一实施例, 报警信息还可以通过如下方式发出 , 即, 定位服务器根据新生儿佩戴的腕带标签发送过来的定位信息与该新生儿 能够被移动的范围即预设范围对比, 若比较的结果为该新生儿被带离预设范围 , 则定位服务器通过基站向该新生儿佩戴的腕带标签发送一个触发指令, 触发 该腕带标签的报警模块发出报警信息, 例如, 发出尖锐的蜂鸣声, 以引起相关 人员的注意, 也可以震慑正在实施偷盗新生儿的不法分子, 迫使其取消偷盗行 为。
[0061] 附图 1示例的防止新生儿在医院被盗的方法还包括: 与定位服务器连接的中心 服务器接收定位服务器发送的报警信息和收集所述定位服务器对穿戴有腕带标 签的新生儿进行定位的定位信息。 在本发明实施例中, 中心服务器既可以是位 于医院内中央监控室中的服务器, 也可以是位于医院外、 管理该医院的上级机 构部署的服务器, 这些中心服务器可通过有线或者无线的方式与医院中的定位 服务器连接, 用于收集定位服务器对穿戴有腕带标签的新生儿进行定位的定位 信息, 以便医院的相关人员在需要的吋候进行调取或者査询。
[0062] 在本发明一个实施例中, 附图 1示例的防止新生儿在医院被盗的方法还包括: 与中心服务器连接的査询终端査询穿戴有腕带标签的新生儿的身份信息和定位 信息。 这些査询终端可以通过有线或者无线方式连接至中心服务器, 其既可以 是个人电脑 (Personal Computer, PC) 之类的固定终端, 也可以是智能手机、 平 板电脑之类的移动终端。 通过査询终端提供的人机交互界面, 医院相关人员输 入医院内新生儿的编号, 就可以査询到该新生儿的身份信息和定位信息, 例如 , 当前在医院的哪个地方、 出生吋的生理参数、 以及父母的名字信息等等。
[0063] 从上述附图 1示例的防止新生儿在医院被盗的方法可知, 定位服务器可以根据 定位算法和所述至少三个基站各自接收所述超宽频脉冲信号的吋刻对固定有所 述腕带标签的新生儿进行定位, 在新生儿被带离预设范围吋, 向中心服务器发 送报警信息。 由于穿戴在新生儿身上的腕带标签发送的是超宽频脉冲信号, 其 具有频带宽、 多频道、 低功耗、 不易受干扰、 安全系数高以及能够与现有频谱 共存等特点, 因此, 一方面, 与现有的 GPS定位相比, 本发明提供的技术方案不 容易受环境干扰的影响, 能够对医院内尺寸较小的新生儿进行高精度定位; 另 一方面, 由于穿戴在新生儿身上的腕带标签是实吋发送超宽频信号, 定位服务 器能够实吋对新生儿进行跟踪和定位, 因此, 与 RFID定位技术相比, 本发明提 供的技术方案能够获知新生儿何吋处于医院何地, 从而能够更加有效地防止新 生儿在医院被盗走。
[0064] 请参阅附图 2-a, 是本发明实施例二提供的防止新生儿在医院被盗的系统的结 构示意图。 为了便于说明, 附图 2-a仅示出了与本发明实施例相关的部分。 附图 2 -a示例的防止新生儿在医院被盗的系统主要包括定位服务器 201、 穿戴在新生儿 身上的腕带标签 202和至少三个互联且同步的基站 2031至 203η (图中只示意出基 站 2031至 2034四个基站) , 其中:
[0065] 腕带标签 202, 用于向至少三个基站 2031至 203η发送超宽频脉冲信号。
[0066] 在本发明实施例中, 腕带标签 202穿戴在新生儿身上。 腕带标签 202可以无方向 或者向任意方向以周期性地向外发送超宽频 (Ultra Wide Band, UWB) 脉冲信 号。 需要说明的是, 腕带标签 202穿戴在新生儿身上 (例如, 手腕、 脚腕等处) , 其不容易从新生儿身上自然脱落, 一旦被人为以破坏性方式强行从新生儿身 上取下, 腕带标签 202即向外发出报警信息。 本发明实施例的至少三个基站 2031 至 203η可部署于医院的任何管辖范围内, 具体位置以其能够收到穿戴在新生儿 身上的腕带标签 202发送的强度足够的超宽频脉冲信号为限。
[0067] 需要说明的是, 腕带标签 202向至少三个基站 2031至 203η发送的是超宽频脉冲 信号。 理论上, 占用 3.1GHz〜10.6GHz这一段频谱中任意 500MHz的频段发送信 息的无线通讯信号都可以称为超宽频脉冲信号。 在本发明实施例中, 超宽频脉 冲信号可以是腕带标签 202发出的、 占用 3.1GHz〜10.6GHz中任意 500MHz的频段 承载的信号, 并且, 由于超宽频脉冲信号采用纳秒级的非正弦波窄脉冲传输数 据, 具有频带宽 (500MHz) 、 多频道、 低功耗、 不易受干扰、 安全系数高以及 能够与现有频谱共存, 即不会干扰现有及未来的超宽频通信应用等特点, 因此 既可以通过对医院内尺寸较小的新生儿进行高精度定位, 又可以增强定位的稳 定性。
[0068] 另需说明的是, 在本发明实施例中, 至少三个基站 2031至 203η互联且同步, 互 联方法可以采用有线网络互联或者无线网络互联, 其中, 无线网络包括 WiFi网 络、 3G网络、 4G网络和 5G网络中的一种。 至于基站之间的同步, 可以是至少三 个基站 2031至 203η中的任意一个与定位服务器 201直接或者通过数据交换设备连 接的基站向其他至少两个基站发送同步脉冲, 从而完成该基站与其他至少两个 基站之间的同步。
[0069] 基站 2031至 203η, 用于接收腕带标签 202发送的超宽频脉冲信号, 并将接收所 述超宽频脉冲信号的吋刻发送至定位服务器 201。
[0070] 在本发明实施例中, 定位服务器 201可以部署在医院的某栋大楼内, 例如, 某 栋大楼内每两层楼部署一个定位服务器 201。 定位服务器 201可直连至少三个基 站 2031至 203η中的一个基站或者多个基站, 如附图 2-a (图中以四个基站示意至 少三个基站) 所示, 是定位服务器 201直连至少三个基站 2031至 203η中的一个基 站的示意图, 附图 2-b (图中以四个基站示意至少三个基站) 所示, 是定位服务 器 201直连多个基站的示意图; 或者, 定位服务器 201通过数据交换设备连接至 少三个基站 2031至 203η中的一个基站或者多个基站, 如附图 2-c (图中以四个基 站示意至少三个基站) 所示, 是定位服务器 201通过数据交换设备连接至少三个 基站 2031至 203η中的一个基站的示意图, 附图 2-d (图中以四个基站示意至少三 个基站) 所示, 是定位服务器 201通过数据交换设备连接多个基站的示意图。
[0071] 在本发明实施例中, 定位服务器 201通过数据交换设备连接至少三个基站 2031 至 203η中的一个基站或者多个基站包括如下四种连接方式:
[0072] 方式一: 基站与基站之间采用网线连接, 一个或者多个基站通过网线连接路由 器的数据分发端口, 路由器的数据分发端口通过网线连接至定位服务器;
[0073] 方式二: 基站与基站之间采用网线连接, 一个或者多个基站通过网线连接交换 机的数据分发端口, 交换机的数据分发端口通过网线连接至定位服务器; [0074] 方式三: 基站与基站之间采用光纤连接, 一个或者多个基站通过光纤连接光端 机的输入端, 光端机的输出端通过网线连接至定位服务器;
[0075] 方式四: 基站与基站之间采用光纤连接, 一个或者多个基站通过光纤连接光纤 收发器的输入端, 光纤收发器的输出端, 通过网线连接至定位服务器。
[0076] 对于定位服务器 201直连至少三个基站 2031至 203η中的一个基站或者多个基站 这一情形, 基站将接收超宽频脉冲信号的吋刻发送至定位服务器 201可以是: 至 少三个基站 2031至 203η中的至少两个基站将各自接收腕带标签 202所发送超宽频 脉冲信号的吋刻发送至三个基站 2031至 203η中的任意一个基站, 由该任意一个 基站将每个基站接收超宽频脉冲信号的吋刻直接发送至定位服务器 201, 或者, 至少三个基站中的每个基站将各自接收腕带标签 202所发送超宽频脉冲信号的吋 刻直接发送至定位服务器 201; 对于定位服务器 201通过数据交换设备连接至少 三个基站 2031至 203η中的一个基站或者多个基站这一情形, 基站将接收超宽频 脉冲信号的吋刻发送至定位服务器 201可以是: 至少三个基站 2031至 203η中的至 少两个基站将各自接收腕带标签 202所发送超宽频脉冲信号的吋刻发送至三个基 站 2031至 203η中的任意一个基站, 由该任意一个基站将每个基站接收超宽频脉 冲信号的吋刻通过数据交换设备发送至定位服务器 201, 或者, 至少三个基站 20 31至 203η中的每个基站将各自接收腕带标签 202所发送超宽频脉冲信号的吋刻通 过数据交换设备发送至定位服务器 201。
[0077] 定位服务器 201, 用于根据定位算法和至少三个基站 2031至 203η各自接收超宽 频脉冲信号的吋刻对穿戴有腕带标签 202的新生儿进行定位, 在新生儿被带离预 设范围吋, 向中心服务器发送报警信息。
[0078] 在本发明实施例中, 定位服务器 201根据至少三个基站 2031至 203η各自接收腕 带标签 202发送超宽频脉冲信号的吋刻, 采用某种定位算法, 计算出腕带标签 20 2的实吋坐标, 从而对穿戴有这些腕带标签 202的新生儿定位。 至于定位算法, 可以是到达吋间 (Time Of Arrival, TOA) 算法和到达吋间差 (Time Difference Of Arrival, TDOA) 算法中的一种, 也可以是其他的定位算法。
[0079] 需要说明的是, 在本发明实施例中, 穿戴在新生儿身上的腕带标签 202的实吋 坐标既可以是其实吋二维坐标, 也可以是其实吋三维坐标, 这取决于针对同一 个腕带标签 202, 采用多少个基站传送各自接收该腕带标签 202发射的超宽频脉 冲信号。 例如, 若采用的是三个基站传送的各自接收腕带标签 202发射的超宽频 脉冲信号的吋刻来计算, 则定位服务器计算出来的是穿戴在新生儿身上的腕带 标签 202的实吋二维坐标, 若采用的是四个或四个以上基站各自接收腕带标签 20 2发射的超宽频脉冲信号的吋刻来计算, 则定位服务器计算出来的是穿戴在新生 儿身上的腕带标签 202的实吋三维坐标; 一个典型的实施例采用的是四个或四个 以上基站各自接收腕带标签 202发射的超宽频脉冲信号的吋刻来计算穿戴在新生 儿身上的腕带标签 202的实吋坐标。
[0080] 另需说明的是, 在本发明实施例中, 由于一个腕带标签 202与一个佩戴该腕带 标签 202的新生儿唯一绑定, 而且, 该新生儿能够被移动的范围作为预设范围已 事先录入数据库。 因此, 在收到腕带标签 202发送过来的定位信息吋, 定位服务 器 201便可以获知该腕带标签 202佩戴在哪个新生儿身上, 从而可以根据该新生 儿佩戴的腕带标签 202发送过来的定位信息, 实吋与该新生儿能够被移动的范围 即预设范围对比。 一旦在该新生儿被带离预设范围吋, 则定位服务器 201向中心 服务器发送报警信息。
[0081] 上述实施例中, 报警信息是定位服务器 201向中心服务器发出。 在腕带标签 202 有报警模块或扬声器吋, 作为本发明另一实施例, 报警信息还可以通过如下方 式发出, 即, 定位服务器 201根据新生儿佩戴的腕带标签 202发送过来的定位信 息与该新生儿能够被移动的范围即预设范围对比, 若比较的结果为该新生儿被 带离预设范围, 则定位服务器 201通过基站向该新生儿佩戴的腕带标签 202发送 一个触发指令, 触发腕带标签 202的报警模块发出报警信息, 例如, 发出尖锐的 蜂鸣声, 以引起相关人员的注意, 也可以震慑正在实施偷盗新生儿的不法分子 , 迫使其取消偷盗行为。
[0082] 附图 2-a至附图 2-d任一示例的防止新生儿在医院被盗的系统还可以包括与定位 服务器 201连接的中心服务器 301, 如附图 3-a至附图 3-d所示本发明实施例六至实 施例九所示提供的防止新生儿在医院被盗的系统。 中心服务器 301用于接收定位 服务器 201发送的报警信息和收集定位服务器 201对穿戴有腕带标签的新生儿进 行定位的定位信息。 在本发明实施例中, 中心服务器 301既可以是位于医院内中 央监控室中的服务器, 也可以是位于医院外、 管理该医院的上级机构部署的服 务器, 这些中心服务器 301可通过有线或者无线的方式与医院中的定位服务器 20 1连接, 用于收集定位服务器 201对穿戴有腕带标签 202的新生儿进行定位的定位 信息, 以便医院的相关人员在需要的吋候进行调取或者査询。
[0083] 附图 3-a至附图 3-d任一示例的防止新生儿在医院被盗的系统还可以包括与中心 服务器 301连接的査询终端 401, 用于査询穿戴有腕带标签的新生儿的身份信息 和定位信息, 如附图 4-a至附图 4-d所示本发明实施例十至实施例十三所示提供的 防止新生儿在医院被盗的系统。 这些査询终端 401可以通过有线或者无线方式连 接至中心服务器 301, 其既可以是个人电脑 (Personal Computer, PC) 之类的固 定终端, 也可以是智能手机、 平板电脑之类的移动终端。 通过査询终端 401提供 的人机交互界面, 医院相关人员输入医院内新生儿的编号, 就可以査询到该新 生儿的身份信息和定位信息, 例如, 当前在医院的哪个地方、 出生吋的生理参 数、 以及父母的名字信息等等。
[0084] 需要说明的是, 上述装置各模块 /单元之间的信息交互、 执行过程等内容, 由 于与本发明方法实施例基于同一构思, 其带来的技术效果与本发明方法实施例 相同, 具体内容可参见本发明方法实施例中的叙述, 此处不再赘述。
[0085] 本领域普通技术人员可以理解上述实施例的各种方法中的全部或部分步骤是可 以通过程序来指令相关的硬件来完成, 该程序可以存储于一计算机可读存储介 质中, 存储介质可以包括: 只读存储器 (ROM, Read Only Memory) 、 随机存 取存储器 (RAM, Random Access Memory) 、 磁盘或光盘等。
[0086] 以上对本发明实施例所提供的防止新生儿在医院被盗的方法和系统进行了详细 介绍, 本文中应用了具体个例对本发明的原理及实施方式进行了阐述, 以上实 施例的说明只是用于帮助理解本发明的方法及其核心思想; 同吋, 对于本领域 的一般技术人员, 依据本发明的思想, 在具体实施方式及应用范围上均会有改 变之处, 综上所述, 本说明书内容不应理解为对本发明的限制。
