金融自助设备及其薄片介质传输系统和传输方法 本申请要求于 2012 年 09 月 21 日提交中国专利局、 申请号为 201210360627.9、发明名称为 "金融自助设备及其薄片介质传输系统和传输 方法"的中国专利申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及薄片介质处理技术， 尤其涉及一种金融自助设备及其薄片 介质传输系统和传输方法。 背景技术
在金融自助设备的薄片介质处理装置中， 一般设有入口处， 出口处， 识别模块， 暂存模块， 只存模块， 循环模块以及连接这些模块的传输通道， 这些传输通道一般靠驱动装置驱动， 通道分叉部分设置有换向器， 纸币在 传输通道传送， 依靠后台控制系统控制换向器向不同方向切换， 将纸币传 送到不同位置。 如图 1所示， 纸币在传输通道 72中状态示意图。 所述传输 通道 72内设置有一换向器 70,在换向器 70沿薄片介质传输方向的上游位 置设置有一检测薄片介质到来的传感器 71。 纸币传送过程中， 当连续传送 的薄片介质 1和薄片介质 2属性不同， 需要传送到不同路径时， 传感器 71 检测到薄片介质 2到来，后台控制系统控制换向器 70切换传输路径。 由于 换向器 70换向需要反应时间，纸币在反应时间内会行进一段距离，我们称 之为换向距离 理想状态下， 薄片介质 2不发生倾斜， 根据换向器工作 原理， 薄片介质 2换向成功必须满足两个条仵 1、 薄片介质 2的换向点（即 传感器 71 )到换向器 70的线距离 S。大于或等于换向距离 S1 ; 2、 薄片介 质 2到达换向点时， 薄片介质 1 已经充分离开换向器 70—段距离 S2。 综 上所述， 薄片介质 2到达换向点时， 薄片介质 1、 2的间距必须大于或等于 最小安全距离
Figure imgf000003_0001
否则薄片介质 2将与换向器 70发生碰撞导致严 重卡纸故障。 如图 2所示， 薄片介质 2发生倾斜的情况下， 薄片介质 2的 换向点到换向器 70的线距离 S。小于换向距离 Sl 薄片介质 1、 2的间距小 于最小安全距离 Smm。 如图 3所示， 薄片介质 1发生倾斜同样会引起间距 变小。
一般情况下，传输通道 72的传输速度一定， 为了保证薄片介质的传输 速度， 往往需要尽可能地缩小相邻两张薄片介质的间距， 现有设备中， 我 们会将相邻两张薄片介质的间距设置为略大于最小安全间距 Smm的值， 这 会引起如下技术问题：
由于设备的频繁使用， 部件磨损老化或者其它异常情况引起传输通道 72不够平滑， 这会引起薄片介质在传输过程中发生倾斜； 薄片介质在模块 之间的交界处及换向器 70处传送时也会出现倾斜，薄片介质 2突然发生倾 斜，导致如图 4和图 5所示的问题， 薄片介质 2的换向点到换向器 70的线 距离 S0小于换向距离 S1 换向器 70换向时， 薄片介质 2已经部分进入换 向器 70, 从而引起卡纸故障。 薄片介质 1突然发生倾斜， 导致如图 6所示 的问题， 薄片介质 1和薄片介质 2之间的间距小于最小安全间距 S 薄 片介质 2在到达换向点需要换向时， 薄片介质 1还没有离开换向器 70, 导 致换向器 70的换向操作失败， 薄片介质 1将与换向器 70发生碰撞导致严 重的卡纸故障， 自助设备会被迫停止服务， 这类严重故障必须维护人员到 达现场进行修复。 发明内容

优选的， 该标准阈值 N大于或等于 0.5%。

由于在薄片介质传输系统中增设了信息采集装置和专门判断和处理薄 片介质倾斜异常的中央处理单元， 使得薄片介质在传输通道中传输至换向 装置前， 增加其倾斜状态的判断， 一旦发现有倾斜状态， 设备即可 ^销换 向装置的换向动作， 终止当前薄片介质的传输， 且设备初始化， 让薄片介 质传输过程重来， 这样， 预测了卡纸故障， 并防止了卡纸故障的发生， 因 此， 本发明提供的薄片介质传输系统出现卡纸故障的几率大大降低， 提高 了设备性能。
此外， 中央处理单元还能计算传输中的每一张薄片介质前端倾斜角度 K1和后端倾斜角度 K2, 且能比较该 K1和 K2是否存在差值， 也就是说， 该张薄片介质是否有倾斜， 若存在差值则记录备案，且统计 K1和 K2存在 差值的概率并记录备案。 这样， 根据薄片介质出现倾斜的概率， 设备维护 人员可预先了解设备可能出现的故障， 及时更换零部件， 防止卡纸故障的 发生。

下面将结合本发明实施例中的附图， 对本发明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发明一部分实施例， 而不是全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没 有作出创造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的 范围。
如图 8所示， 本发明一较佳实施例提供的薄片介质传输系统 100包括 至少两条相接的薄片介质传输通道； 至少一换向装置 65 , 设置在该两条薄 片介质传输通道相接处， 控制薄片介质的传输方向； 至少一信息采集装置 61 , 设置在该薄片介质传输通道上沿薄片介质传送方向相对于该换向装置 的上游位置， 用于检测薄片介质的到来并采集当前薄片介质的倾斜信息； 以及一中央处理装置 60, 用以计算当前薄片介质倾斜角度和当前薄片介质 间距， 并判断该当前薄片介质倾斜角度或间距是否异常， 判断为否时切换 该换向装置， 判断为是时终止切换该换向装置并控制该薄片介质传输系统 停止传送薄片介质及执行初始化步骤。
具体的， 该中央处理装置 60包括： 一存储单元 66, 用于存储该信息 采集装置采集到的倾斜信息及标准阈值； 一换向控制单元 64, 用以控制该 换向装置在不同传送通道间切换； 一异常判断单元 62, 用以计算当前薄片 介质倾斜角度且判断该倾斜角度是否异常， 以及计算当前薄片介质间距并 判断该当前薄片介质间距是否异常； 以及一异常处理单元 63 , 用以在该异 常判断单元判断结果为异常时， 终止切换该换向装置， 以及控制该薄片介 质传输系统停止传送该薄片介质并执行初始化步骤。
该实施例提供的薄片介质传输系统 100其薄片介质传输方法包括： 步 骤一， 通过信息采集装置获取换向装置换向前的前后两张薄片介质的倾斜 角度 K5和 K6, 其中 K5为前一张薄片介质的后端倾斜角度， K6为后一张 薄片介质的前端倾斜角度； 步骤二， 将 K5和 K6与一标准阈值 M比较， 若任一值大于标准阈值 M, 执行步骤三， 否则切换换向装置并继续传送当 前薄片介质； 以及步骤三， 终止切换该换向装置， 停止传送当前薄片介质 并执行初始化步骤。
也就是说， 该实施例提供的薄片介质传输系统 100能自动检测薄片介 质传输状态并能根据传输状态异常的情况可 ^销换向装置的换向动作， 终 止当前薄片介质的传输， 且设备初始化， 让薄片介质传输过程重来， 这样， 预测了卡纸故障， 并防止了卡纸故障的发生。
本发明的另一实施例所提供的薄片介质传输系统与该薄片介质传输系 统 100相比， 在中央处理装置上有进一步的改进， 如图 9所示， 该实施例 中中央处理装置 60，除了包括一存储单元 66, —换向控制单元 64, —异常 判断单元 62以及一异常处理单元 63外，进一步包括：一异常比较单元 67, 用于比较当前薄片介质前后端倾斜度是否变化； 一倾斜概率计算单元 68, 用于统计该薄片介质前后端倾斜度发生变化的概率； 以及一结果输出单元 69, 用于输出该薄片介质前后端倾斜度发生变化的概率。
对应的， 本实施例提供的薄片介质传输系统其薄片介质传输方法还包 括步骤四， 通过信息采集装置获取每张薄片介质前端倾斜角度 K1 和后端 倾斜角度 K2; 步骤五， 比较该 K1和 K2是否存在差值， 若存在差值则记 录备案；步骤六，统计 K1和 K2存在差值的概率并记录备案；以及步骤七， 将 K1和 K2存在差值的概率与一标准阈值 N比较，如果大于该标准阈值 N, 则输出 "异常" 的结果， 以提示设备维护人员检修， 如果小于该标准阈值， 则输出 "正常" 的结果。
因此， 对应的， 该实施例提供的薄片介质传输系统除了能自动检测薄 片介质传输状态异常并 ^销换向装置的换向动作， 终止当前薄片介质的传 输且初始化设备外， 还可根据薄片介质在传输通道某路段发生倾斜的概率 预测设备发生故障的几率， 及时提醒设备维护人员更换零部件。
本发明提供的薄片介质传输系统应用于自动拒员机中， 如图 7为自动 拒员机概略图，该自动拒员机包括设置于上部机芯 51的用于投入纸币的入 口部 1 , 用于取出纸币的出口部 2、 用于鉴别纸币真伪的识别模块 3、 在交 易确定之前临时存放纸币的暂存模块 4、设置于下部机芯 52的用于存储不 合格纸币的只存箱 5、 存储合格纸币的第一循环箱 6、 第二循环箱 7、 第三 循环箱 8及第四循环箱 9、 及对上述各模块进行控制的控制模块 53 , 上述 中央处理装置 60或 60，集中在该控制模块 53中。
在入口部 1的输出端和识别模块 3输入端之间设置有第一传输通道 10, 在第一传送通道 10的中途设置有用于将纸币分配到下部机芯 52的第一换 向装置 21。在识别模块 3的输出端和出口部 2输入端之间设置有第二传送 通道 11 , 在第二传送通道 11中途设置有用于连通第三传送通道 13的第二 换向装置 22。 第三传送通道 13另一端连接在暂存模块 4上， 所述第二换 向装置 22可实现暂存模块 4、 出口部 2和识别模块 3之间三向自由连通。 所述第一换向装置 21与第四循环箱 9之间设置有第四传送通道 14, 用于 接纳被分配到下部机芯 52的纸币。 所述第四传送通道 14上依次设置有第 三换向装置 23、 第四换向装置 24、 第五换向装置 25、 第六换向装置 26, 用于将纸币分别分配到只存箱 5、第一循环箱 6、第二循环箱 7及第三循环 箱 8。

下面结合图 7以存款动作中点钞流程为例说明纸币传送的处理过程。
(1)客户将待存款的纸币放置在图 7中入口部 1 , 控制模块启用其通道 电机控制模块， 使传输通道按照正转方向传送纸币。 入钞口部组件将纸币 一张张分离后进入到第一传输通道 10上。
(2)纸币离开入钞口部后， 在传输通道上依次经过第一传感器组 31、 第 二传感器组 32, 进入到识别模块 3 , 识别模块 3负责鉴别纸币的真伪、 面 额、 币种、 重张等信息。
(3)纸币在离开识别模块 3以后， 经过第三传感器组 33后进入第二传 送通道 11 , 换向器控制单元需要根据此时纸币的状态确定纸币的最终目的 地， 打开 /关闭第二换向装置 22, 使纸币在正确的传输路径传输。 正常纸币 依次经过第五传感器组 35后被传送至暂存模块 4, 异常纸币被换向到第三 传送通道 13 , 经过第四传感器组 34被传送至出口部 2。所有的纸币都被传 送至出口部 2或者暂存模块 4以后， 根据用户确认信息， 暂存模块 4处纸 币沿着原路退回到第一传送通道 10后， 经过第一换向装置 21换向， 被传 送到第四传送通道 14 , 按照当前纸币属性传送到不同的循环箱。
为详细阐述本发明， 以图 7中的虚线框标示部分 54筒化成图 10来说 明。 这部分包括第二传输通道 12, 识别模块 3 , 设置在两模块接口处的第 三传感器组 33、设置在第二传送通道 12上的第二换向装置 22以及传输状 态的纸币 1。 本发明的采集单元为并列设置的第一传感器 331和第二对感 器 332构成的传感器组 33 , 在传输路径上用于检测纸币的到来并配合中央 处理装置中的异常判断单元判断纸币的顶端和底端倾斜情况。
首先介绍模块异常预测。 在纸币的传送过程中， 异常判断单元监控第 一传感器 331和第二传感器 332遮挡和不遮挡的状态变化， 并实时纪录这 些状态的变化时刻。 当倾斜度为 0的纸币通过该处传感器时， 这两对对射 传感器能同时检测到钞票的顶端进入和钞票底端的离开。 当纸币倾斜度不 为 0时， 检测信号如图 11所示， TO为第一传感器 331检测到纸币进入的 时间， T1为第二传感器 332检测到纸币进入的时间， T2为第一传感器 331 检测到纸币离开的时间， T3为第二传感器 332检测到纸币离开的时间。
检测流程如图 12所示， 当检测到第一传感器 331或者第二传感器 332 的状态由不遮挡变为遮挡时（步骤 S302和步骤 S304 ) , 分别记录下这两个 传感器状态变化时刻 1^和 T , (步骤 S303和步骤 S305), 异常判断单元计 算出两传感器时间差 T «=TrT。， 已知第二传送通道的速度 S, 第一传感 器 331和第二传感器 332之间的距离为 L,根据公式 arctan(ri -rO) * S /L得到 纸币顶端在第三传感器组 33位置的倾斜度 K «。 接着当检测到第一传感 器 331或者第二传感器 332的遮挡变为不遮挡时（步骤 S308和步骤 S310 ), 分别记录下这两个传感器状态变化时刻 T2和 Τ3 (步骤 S309和步骤 S311 ), 异常判断单元计算出两传感器时间差 Τ 底 =Τ3-Τ2 , 根据公式 arctan(ri-rO) * S /L得到纸币底端在第三传感器组 33处的倾斜度 K底差。
异常比较单元 67比较 K顶差和 K & , 当 IK 顶差 -K底差 I >M=12。 ， 说明纸 币在第三传感器组 33处， 即识别模块 3与第二传送通道 11的接口处发生 了严重扭曲。 倾斜概率计算单元 68统计每张纸币通过第三传感器组 33发 生倾斜的概率， 记录成如图 13 中纸币状态记录表中， 存储到存储模块 66 中， 在维修人员对设备进行定期检查时， 设备切换成后台维护模式 (S501), 控制模块 53将存储模块 66中记录的第三传感器组 33处纸币发生异常状态 的比例 X与阀值 N进行比较， 本实施例中 Ν=0.5% , 异常比例 X大于阀值 N 时， 认为该传感器或者传感器区间为预计可能产生故障的传递区间 ( S503 ) ,通过输出单元 69显示如图 12所示的故障预测详细信息（ S504 ), 所有的传感器组以及传感器组区间的异常次数都在阀值之内时， 主控制部 在界面上显示 "正常" 的画面 （S507 ), 提示设备运行良好无需进行检修。 当维护人员根据故障预测详细信息中的提示信息对设备完成检修后， 可以 清除检修模块的异常次数记录，以便再次重新统计出现的异常比例（ S506 )。
下面介绍异常处理。 参见图 14和图 10, 若当前纸币 2与前一张纸币 1 需要传送到不同路径， 则需要切换第二换向装置 22。 异常判断单元 62则 需要判断当前纸币 2与前一张纸币 1之间的状态是否异常， 即当前纸币 2 与前一张纸币 1的间距 N是否大于最小安全距离 D, D的取值与通道速度 及换向装置的反应时间有关， 本发明设备中设 D=36mm。 在本发明应用的 设备中， 前一张纸币 1与当前纸币 2之间的距离 H设定为略大于最小安全 距离 D的值， 如果前一张纸币 1或当前纸币 2任一发生倾斜， 则有可能引 起 H小于 D, 从而造成换向失败。
本发明中采用判断换向动作前后两张纸币的倾斜情况来判断纸币的状 态是否异常， 从而预测可能发生卡钞的情况。 纸币在传送过程中， 监控当 前纸币 2和前一张纸币 1在传感器组 33处遮挡和不遮挡的状态变化情况， 并实时纪录这些状态的变化时刻，异常判断单元 62对前一张纸币 1尾端和 当前纸币 2前端的斜度进行判断， 当任一值大于标准阈值 M, 即判定倾斜 异常， 则执行初始化步骤， 具体判断步骤如下：
传感器组 33侦测到前一张纸币 1到来， 检测信号如图 11所示， 检测 流程如图 12所示，当检测到第一传感器 331或者第二传感器 332的状态由 不遮挡变为遮挡时（步骤 S302和步骤 S304 ), 分别记录下这两个传感器状 态变化时刻 T。和 T , (步骤 S303和步骤 S305), 接着当检测到第一传感器 331或者第二传感器 332的遮挡变为不遮挡时 （步骤 S308和步骤 S310 ), 分别记录下这两个传感器状态变化时刻 Τ2和 Τ3 (步骤 S309和步骤 S311 ), 异常判断单元 62计算出两传感器时间差 Τ
Figure imgf000014_0001
已知第二传送通道 11的速度为 S, 第一传感器 331和第二传感器 332之间的距离为 L, 根据 公式 arctan(T3-T2)*S/L得到前一张纸币 1的尾端在第三传感器组 33处的倾 斜情况 K底差。
当传感器组 33侦测到当前纸币 2到来时，第一传感器 331或者第二传 感器 332的状态由不遮挡变为遮挡时（步骤 S302和步骤 S304 ), 分别记录 下这两个传感器状态变化时刻 T。和 T , (步骤 S303和步骤 S305), 已知第 二传送通道 11的速度为 S, 第一传感器 331和第二传感器 332之间的距离 为 L, 根据公式 arctan(ri-rO) *S /L， 得到当前纸币 1 前端在第三传感器组 33处的倾斜情况 K «。异常判断单元 62将 底^和 Κ «分别与存储模块中 存储的标准阈值 Μ 比较， 若 Κ 底^或 Κ 任一值大于阀值 Μ, 本例中 Μ=12。 ， 则判定倾斜异常， 异常处理单元 63向换向控制单元 64发送控制 指令， 控制换向装置 65停止换向， 并立刻取消正在进行的交易， 所有的传 送通道立刻停止传输， 在纸币出现卡死之前立刻停止设备的运行， 这样可 以避免前一张纸币 1或者当前纸币 2即将出现的与换向器碰撞卡纸故障。 交易取消后， 设备进行复位， 这样设备通过自动复位后恢复交易， 减少了 设备的停机时间。
通过以上动作， 根据薄片介质该传送状态的变化确定预计将产生的故 障。 传送状态的变化如果会影响到当笔交易的正常进行时， 设备预测到这 种故障后立刻停止交易， 然后自动复位后恢复交易， 不需要维护人员到达 现场进行修复。 在维护人员定期检查时， 可根据记录的这些详细信息对设 备进行检修， 更换消耗品， 清除灰尘等对策， 能够在产生故障前消除故障 隐患， 能够减少故障导致的设备停机。 本实施例分别节选了其中一组传感器与换向装置配合预测换向器卡 钞， 及一组传感器预测模块异常的实例进行说明， 在设备其他部位设置的 对应薄片介质处理系统与本实施例完全相同， 该薄片介质处理系统也可以 用在设备其他部位解决相同技术问题。
以上所述是本发明的优选实施方式， 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， 这些改进和润饰也视为本发明的保护范围。
