伪证券检测设备 Pseudo Securities testing equipment

本发明涉及对可疑伪券进行磁检测的设备和方法。 The present invention relates to apparatus and suspected counterfeit notes in magnetic detection.

计数、检验、堆垒特定类型的证券(如,货币)的证券计数和处理设备是公知的。 Counting test, a particular type of security heaps (e.g., currency) the document counting and processing apparatus are well known. 其中有一种利用模拟比较电路检验证券的光和磁特性是否落在由偏置该比较电路的分立电子元件确定的阈值内的设备。 Wherein there is a comparator circuit using an analog optical and magnetic properties of examining the security of the device falls within a threshold of the discrete electronic components by the bias circuit is determined by comparison. 为了采用这些设备计数和检验其光或磁特性不相同的证券,必须手动调节模拟比较电路的偏置元件。 To use these devices and testing their counts optical or magnetic properties different securities must manually adjust the biasing components of the analog comparator circuits. 在适合于一种类型证券(如,美国货币)的现有技术的证券计数设备中可实现核实检验的特定组合,但这种特定的组合不可能适合于其它类型的证券,例如赠券、美国食品印花、或除美国外的其它国家的货币。 Suitable for one type of security (e.g., U.S. currency) document counting apparatus in the prior art may be implemented to verify the specific combinations tested, but this specific combination not be suitable for other types of securities, such as coupons, U.S. food stamp, or currency except the United States or other countries. 因此,人们希望为证券计数设备提供一种控制系统,使得计数设备可有选择地进行核实检验以及能容易地选择检验阈值和步骤来符合各种证券的特征和特性。 Accordingly, it is desirable to provide a control system for the document counting device such that the device can be selectively count verification test and inspection can be easily selected to meet the threshold and the step of features and characteristics of the various securities.

我们发现,由于在计数设备中存在来自各种噪声源的电噪声,因此在高速证券计数设备中根据证券的光和磁性准确检验证券是很困难的。 We found that, due to the presence of electrical noise from various noise sources in the counting device, and therefore high-speed document counting device is difficult to accurately examining the security light according to a magnetic securities. 为了提高检验真证券的可靠性,期望提供一种可基本上免除电噪声影响的证券检验系统。 In order to improve the reliability of testing truth securities, securities desirable to provide an inspection system is basically exempt from noise power.

按本发明的一个方面,为证券计数和分选设备提供一个由可编程微处理器控制的控制系统。 According to one aspect of the present invention, there is provided a control system controlled by a programmable microprocessor for the document counting and sorting apparatus. 该微处理器连到一个通道模/数(A/D)转换器,该转换器对来自光和磁证券检测设备的模拟信号取样。 The microprocessor is connected to a channel analog / digital (A / D) converter which converts analog signals from optical and magnetic document detection sampling device. 在处理每一个证券时,微处理器经A/D转换器累加多个来自传感器的取样值。 When the processing of securities each, microprocessor via A / D converter samples the plurality of accumulated values ​​from the sensor. 该累加的取样值与可编程的阈值和/或限值比较,以便在证券通过设备传送时检验每一个证券。 Sampling programmable threshold value and / or comparing the accumulated value in order to check each of the securities transmitted through the security device. 每次通过用户来选择用于检验证券磁性的阈值和限值,或者对这些阈值或限值重新编程(这是很容易作到的),以便检验不同类型的证券。 Each selected threshold value, and a magnetic test securities by the user, or to reprogram these threshold values ​​or the limit value (which is easily done) in order to test different types of securities. 例如,更新非易失存贮器(包含微处理器执行的检验参数和控制程序)可能会便利于这种重新编程。 For example, updating the non-volatile memory (includes test parameters and control program executed by the microprocessor) could facilitate this re-programming.

按本发明的另一方面,证券计数设备包括一个用于具有磁性的证券的证券磁检验系统,并且该系统的特征是减小噪声的影响。 According to another aspect of the present invention, a document counting apparatus comprising a magnetic security inspection system for securities having magnetic properties, and the feature of the system is to reduce the influence of noise. 证券磁检验系统使用了一个读出磁头,它响应于具有磁性的证券通过磁头时产生一个感应电信号。 Magnetic security inspection system uses a read-out head, responsive to the electrical signals generated by a magnetic head having a magnetic securities. 磁头刚性地装到一个证券导向板上。 A magnetic head is rigidly mounted to the guide plate stock. 在本发明的一个实施例中,将一个加强证券磁性的磁铁也刚性地装在读出磁头上,使二者成固定关系,从而和读出磁头一起形成了一个单一的机械连接。 In one embodiment of the present invention, the magnet is a magnetic security strengthening is also rigidly mounted on the read head, so that the two fixed relation to the read head and form a single mechanical connection together. 当证券沿导向板传送时,定位在读出磁头上方的路径约束轮使证券在读出磁头附近均匀接近通过。 When the securities transmitted along the guide plate, positioned above the path of the read head restraint wheel to securities in the vicinity of the read head is accessible through uniform. 信号调节电路处理来自读出磁头的感应电信号,以提供具有低噪声含量的调节信号。 Signal conditioning circuit processes the induced electrical signal from the read head to provide a conditioned signal having a low noise content. 在优选实施例中,信号调节电路包括一个带通滤波器,用于除去来自读出磁头的感应电信号的高频噪声分量和低频噪声分量。 In a preferred embodiment, the signal conditioning circuit comprises a band-pass filter for removing high frequency noise from the electrical signals of the reading head components and low noise component. 在证券通过读出磁头期间,通过A/D转换器对被处理的信号进行多次信号取样,以便产生一个由微处理器累加的值。 , D converter to signal processing performed by the securities during the read head by the A / multiple signal samples to produce a value accumulated by the microprocessor. 在证券通过了读出磁头后,对累加的值求平均,并且同一个或多个预定的基准值比较,以便对具有预定的或可接受的磁特性或磁性的证券进行检验核实。 After the securities by the read head to find the value of accumulated averaged and compared with a predetermined reference value or more, for verification or verification of the magnetic properties or magnetic pharmaceutically having a predetermined securities.

按本发明的另一个实施例,为证券计数设备提供一个伪券检测系统,以便可用于检验具有不同磁特性的证券。 Another embodiment according to the present invention, there is provided a detection system for the counterfeit notes document counting apparatus, so as to be used to verify securities having different magnetic properties. 这样一些证券(例如中华人民共和国发行的50元钞票)若和美国货币相比,其磁性较弱和/或磁性区更小。 Some such securities (eg People's Republic of China issued 50 dollar bills) and if the US currency compared to the weak magnetic and / or magnetic zone smaller. 在检测和核实相当小的可磁化的证券的过程中,为一个强化的伪券检测系统提供一个高增益、低噪声的信号调节电路,以便连接读出磁头和控制用的微处理机。 Detection and verification process relatively small magnetizable securities, there is provided a reinforced counterfeit-note detection system a high-gain, low-noise signal conditioning circuit, connected to the read head and the control of the microprocessor used. 当每一张证券传送通过读出磁头时,A/D转换器在微处理器控制下取出调节信号的多个信号取样值。 When each of the securities transmitted through a read head, A / D converter plurality of signal samples taken in the adjustment signal under microprocessor control. 将每个取样值都和一个或多个基准值比较,微处理器相对于基准值对落在基准值的一个预定范围内的多个相继取样值的数目进行累加计数。 Each sample values ​​and comparing one or more reference values, the reference value of the microprocessor with respect to the number of the plurality of successive sample values ​​falling within a predetermined range of reference values ​​is accumulated count. 累加的计数又依次和一个或多个与真券相关的基准值比较,确定被处理的证券是否具有可接受的磁性。 And in turn accumulated counts associated with a plurality of genuine note or a reference value, and determines whether the processed securities magnetic acceptable.

图1表示一个有价证券计数和分选设备10。 1 shows a value document counting and sorting apparatus 10. 在设备10中,将有价证券放入斗仓12中,借此把证券送到设备10内进行计数或分选。 In the apparatus 10, the securities into the hopper 12, whereby the security device 10 to be counted or sorted. 证券通过设备10后由叠放轮18叠放在叠放板20上。 Securities by the device 10 stacked on the stacking plate 20 by the stacking wheel 18. 该设备的控制板包括显示器16(如,LCD显示器),向用户显示计数、总数和状态信息。 The apparatus includes a display panel 16 (e.g., LCD displays), displays the count, and the total number of status information to the user. 用键盘14向设备手动输入控制命令。 14 controls the keyboard command to the input device manually.

就有价证券输送机构而论,现参照图2A,把一叠证券22放入斗仓12中并使它们静止在斗仓板24上。 Securities respect to transport mechanism, referring now to Figure 2A, the security stack 22 into the hopper 12 and resting them on the hopper plate 24. 在斗仓12的两侧对齐一个LED65和一个光传感器64,检测斗仓12中是否存在有价证券。 On both sides of a hopper 12 is aligned with a photosensor 64 and LED65, hopper 12 detects the presence or absence of securities. 在分拣轮轴28上安装一对分拣轮(如,分拣轮26),轴28位于斗仓板24的下方。 Shaft 28 mounted on the sorter sorting one pair of wheels (e.g., sorting wheel 26), the shaft 28 is located below the plate 24 of the hopper. 摩擦式分拣表面30围绕着分拣轮26的周边的一部分。 Sorting friction surface portion 30 around the periphery of the wheel 26 of the sorter. 分拣轮26一转动,分拣表面30就穿过斗仓板24中的一个孔、与最下边的证券22摩擦啮合,并迫使这些证券22移向供给轮组件32。 A sorting wheel 26 is rotated, surface 30 will pass through a sorting hole hopper plate 24, frictionally engages the lowermost 22 securities, securities and 22 forcing them toward the feed wheel assembly 32.

当供给轮32与最下边的证券摩擦啮合时,剥离组件(用标号36总体表示)沿和供给轮32转动方向相反的方向提供剥离作用,挤压最下边的证券,使这些证券一次一张地通过该设备,对此下面还要作更加全面的介绍。 When the supply wheel 32 frictionally engages the lowermost securities, stripping assembly (generally indicated by reference numeral 36) and the supply wheel 32 rotates in an opposite direction to provide peeling action, pressing the lowermost securities, securities these one at a time With this equipment, the following should make this a more comprehensive introduction. 剥离组件36由驱动轴48驱动,在轴48上装有驱动皮带轮40。 Release assembly 36 driven by the drive shaft 48, with shaft 48 in the drive pulley 40. 驱动皮带轮40与剥离组件的摩擦式皮带38啮合,皮带38绕驱动皮带轮40和装在惰轮轴44上的惰轮42转动。 Drive pulley 40 and release assembly engaging the friction belt 38, the belt 38 around the drive pulley 40 and idler shaft 44 mounted on the idler gear 42 is rotated. 对剥离组件皮带38进行选择,使其与证券22的摩擦系数小于证券与供给轮32周边表面的摩擦系数,因此这种剥离作用不能克服供给轮32的供给作用。 Peeling the belt assembly 38 are selected so that the coefficient of friction and a coefficient of friction less than 22 securities securities and the peripheral surface of the supply wheel 32, so that the peeling effect can not overcome the feeding action of the feed wheel 32.

经常发生的情况是,有价证券(如,现金)的摩擦特性取决于证券的年代和状态,并且还取决于环境特性(如,湿度)。 Often it happens that the frictional characteristics of securities (e.g., cash) depends on the state's and securities, and also on the environmental characteristics (e.g., humidity). 为了在证券22加入设备中时能调节加到证券22上的剥离摩擦作用,要为惰轮轴44提供可转动的偏心轴承46,可以转动该轴承46以调节惰轮轴44相对于驱动轴48的位置。 In order to adjust the friction action on the release 22 when applied to securities added security device 22, idler shaft 44 is provided to be rotatable eccentric bearings 46, the bearing 46 may be rotated to adjust the position of the idler shaft 44 relative to the drive shaft 48 . 这种调节作用改变了剥离组件摩擦式皮带38中的张力,并且可利用这种调节作用来改变证券加入设备10中时由剥离组件摩擦式皮带38加到证券22上的正常作用力。 This changes the tension regulation of the friction belt stripping assembly 38, and may utilize such added securities regulation device to alter the normal force on the friction assembly 22 by the release belt 38 is added to the stock 10.

图3A表示一个优选的可替换的剥离组件,一般由标号36a表示。 3A shows a preferred alternative stripping assembly, generally designated by the reference numeral 36a. 张紧惰轮70在驱动皮带轮40和惰轮套42a之间和剥离组件皮带38啮合。 Tensioning idler pulley 70 in the drive sleeve 40 and the idler 38 and the engagement between the release belt assembly 42a. 当证券被迫向剥离组件皮带38的表面移动时,张紧惰轮70通过阻止由剥离组件皮带38形成的环路的向里变形来保持剥离组件皮带38中的张力。 When securities are compelled to move the release surface 38 of the belt assembly, by preventing the tension idler 70 to the loop formed by the belt 38 in the modified release component to maintain the belt 38 in tension stripping assembly. 在轴72上安装该张紧惰轮70,轴72是通过可枢轴转动的托架71从剥离组件驱动轴48悬垂下来的。 The tensioner idler 70 is mounted on shaft 72, shaft 72 is pivotable by a bracket 71 of the drive shaft 48 is suspended from the release assembly.

由图3B可见,惰轮套47在惰轮轴73a上自由旋转。 It is seen from FIG 3B, the idler gear 47 rotates freely on the sleeve idler shaft 73a. 通过螺钉113将惰轮轴73a紧固到侧板33和34上。 The idler shaft 73a is fastened to the side plates 33 and 34 by screws 113. 现在回到图3A,由图可见,凸缘63a的表面与供给轮32的表面相接触,因此证券和供给轮依然保持摩擦接触,并且证券在凸缘63a和供给轮32之间沿导向路径被推向前进。 Returning now to Figure 3A, seen from the drawing, the surface of the flange 63a and the surface of contact with the supply wheel 32, and thus the supply of securities remains in frictional contact wheel, and securities between the flange 63a and the supply wheel 32 along the guide path forward. 回到图3B,图示了一个用标号114表示的枢轴地支承在惰轮轴73a上的托架114。 Back to Figure 3B, illustrates a pivotally supported by a reference numeral 114 denotes a carriage on a shaft 73a of the idler 114. 通过螺钉115将短轴44a的一端固定到托架114上。 The end of the short axis 44a is fixed to the bracket 114 by screws 115. 按可转动方式把张力调节轮42a安装在短轴44a上,其安装位置靠近短轴44a的和螺钉115相对的那一端。 By rotatably adjusting the tension wheel 42a mounted on the minor axis 44a, and the mounting position close to the minor axis of the screw 115 44a opposite that end. 如由图3A清晰可见,张力调节轮42a与剥离组件摩擦式皮带38的下端啮合。 As clearly seen from FIG. 3A, the tension adjusting assembly and the peeling wheel 42a frictionally engaging the lower end 38 of the belt.

现在参看图3C,其中的托架114在其相对于惰轮轴73a上的可枢轴转动的端部的相对端处有一对夹板106和107。 Referring now to Figure 3C, wherein the carrier 114 with respect to the opposite end of the end portion may pivot on the rotation of the idler shaft 73a has its pair of clamps 106 and 107. 凸轮117偏心地安装在夹板106和107之间的调节轴116上。 The cam 117 is eccentrically mounted on the adjusting jaws 106 and 107 between the shaft 116. 由图3A可清楚看到,凸轮117在调节轴116上的转动使托架114的夹板端能在轴73a上绕托架114的可枢轴转动端枢动转动。 It can be clearly seen from FIG. 3A, the adjustment cam 117 is rotated on the shaft 116 so that the jaws can rotate about the end bracket 114 of the bracket 114 is pivotally end pivotally rotates on shaft 73a. 在托架114转动时,短轴44a凭借短轴44a和托架114之间的安装关系可上、下垂直移动。 When the bracket 114 is rotated, the minor axis 44a by virtue of the relationship between the minor axis mounting bracket 44a and 114 may be upper and lower vertical movement. 短轴44a随轮42a的相应的上、下移动垂直平移,从而可增、减剥离组件38中的张力。 44a with the minor axis of the respective wheel 42a, the lower vertical translation movement, thereby increasing and decreasing the tension in the stripping assembly 38. 因此应该认识到,凸轮117是由托架夹紧或夹持住的,所以托架才能绕惰轮轴73a枢轴转动,除夹板端以外还可以利用其它的装置来通过托架夹紧凸轮。 Therefore it is appreciated that the cam 117 is clamped or gripped by the carrier, so the carrier can pivot about an idler shaft 73a, in addition to the other end of the clamp means may also be utilized to clamp the cam by the bracket.

使用几个传感器(设备控制系统的一部分)检测证券在通过设备的加速轮52、54附近时的磁特性。 Using several sensors (a part of a device control system) detecting magnetic properties of securities at the time of acceleration wheels 52, 54 through the vicinity of the device. 如图3A所示,在下导向板50的上方靠近证券导向路径中央的位置定位一个光源,如中央LED81。 Above, the lower guide plate of FIG. 3A 50 positioned proximate the center of the guide path securities one light source, such as a central LED81. 中央LED81发光,该光由装在下导向板50的下方的一个光传感器(如中央传感器80)检测,由此可对在LED81和传感器80之间是否存在证券进行光检测。 LED81 emitting center, the light emitted by a light sensor mounted beneath the lower guide plate 50 (e.g., the center sensor 80) is detected, whereby whether or not there between the LED81 and the light detection sensors 80 securities. 如图4所示,中央传感器80装在下导向板50中的孔51内。 As shown, the center sensor 80 mounted within a bore 50 in the guide plate 51 the lower 4. 左传感器82装在下导向板50的左侧的孔53内。 Left sensor 82 attached to the lower left side of the inner bore 50 of the guide plate 53. 右传感器84装在下导向板50的右侧的孔55内。 Right sensor 84 attached to the lower right side of the inner bore 55 of the guide plate 50. 用左、右传感器82、84检测证券沿传感器附近的下导向板50传送时传感器检测的证券的左、右侧段(在图4中一般用标号99、97表示)的存在状态和遮光性。 With the left, the left security when transmitting sensor for detecting the vicinity of the right lower guide plates 82, 84 of the sensor along the sensor 50 detects the securities, the right section (generally designated 99,97 is shown in FIG. 4) is present and the light blocking state. 左、右传感器82、84要与相应的左、右LED′83、85协调动作。 Left and right sensors 82 and 84 to the respective left and right LED'83,85 cooperative operation. LED′83、85安装在上导向板内,其设置情况与结合图3A所述的中央LED81和中央传感器80的设置情况类似。 LED'83,85 mounted in the guide plate, similar to the case is provided which is provided in conjunction with the case of FIG central LED81 and the central sensor of the 3A 80. 应注意,分别设在上、下导向板中的LED′和光传感器的相对位置可以颠倒过来而不会影响对其中通过的证券的检测。 It should be noted, are provided on, "the relative position of the lower guide plate and an LED light sensor may be reversed without affecting the detection of which by the securities. 进一步还应注意,可以按其它方式使用除LED′外的光源和除光晶体管外的光检测器来获得这里所述的检测功能。 It should also be noted that further may be used in addition to LED 'outside source and the light detector except phototransistor is obtained by other means detecting the functions described herein. 最后还要注意,在图4中表示的左、右和中央光传感器是定位在横过或垂直于证券导向路径的一条直线上的,但这些传感器可能有不同的取向。 Finally, note, shown in the left in FIG. 4, right and center the optical sensors are positioned in a line across or perpendicular to the stock guide path, these sensors may have different orientations.

还要对通过该设备的证券进行磁检测。 But also on the securities by the magnetic detection device. 现在回到图3,在导向板50下方的一个圆形板90上安装一个磁场检测器,例如读出磁头86,确定磁场检测量的位置,使其在下导向板50的表面上方略微凸出一点。 Returning now to FIG. 3, a little above the slightly convex surface of a circular mounting plate 50 beneath the guide plate 90 on a magnetic field detector, such as read head 86, determines the amount of magnetic field detecting the position of the lower guide plate 50 so . 该读出磁头86最好是由Michigan Magnetics Inc.ofVermontville,Michigan制造的全磁迹单磁头,其标称电感为300mH,在1KHz时的阻抗为2kΩ,直流电阻为270Ω。 The read head 86 is preferably a single full-track head manufactured by Michigan Magnetics Inc.ofVermontville, Michigan, which is a nominal inductance of 300mH, when the impedance is 2 k [Omega 1KHz, the DC resistance of 270Ω. 读出磁头86提供代表沿下导向板50前进的证券的磁特性和磁性质的电信号。 Representative of the read head 86 provides an electrical signal along a lower guide plate and the magnetic properties of the magnetic properties of securities 50 forward. 为了增强感应的电信号,在下导向板50的下方定位一个磁通源,例如永久磁铁88,使证券在读出磁头86上方通过之前就已磁化。 To enhance the induction of an electric signal, below the lower guide plate 50 is positioned in a magnetic flux source, such as permanent magnet 88, so that the magnetization of securities already in the read head 86 before passing through the top.

设备中机械振动具有在读出磁头86的电信号中引入不期望的变化的趋势,这可能是由于振动引发在磁铁88读出磁头86、和在读出磁头86上方通过证券之间的相对位置的涨落变化。 The mechanical oscillation has introduced an undesirable change in the electrical signal read head 86 in the trend apparatus, which may be caused due to vibrations of the magnet read head 8886, and a read head 86 over the relative position between the securities fluctuations change. 为了将磁铁88相对于读出磁头86的振动减至最小,要按刚性的、固定的相互关系安装磁铁88和读出磁头86,形成单个的结构单元。 The magnet 88 with respect to the read head 86 to minimize the vibration, according to a rigid, fixed relationship between the magnet 88 and mounting the read head 86, to form a single structural unit. 例如,在优选实施例中,通过刚性固定件(如,双头螺栓92)将圆形板90固定到下导向板50上,并且通过刚性固定件(如,双头螺栓94)把磁铁88也固定到下导向板50上。 For example, in a preferred embodiment, by a rigid fixing member (e.g., stud 92) circular plate 90 is fixed to the lower guide plate 50, and by a rigid fixing member (e.g., stud 94) is also the magnet 88 It is fixed to the lower guide plate 50. 把读出磁头86和磁铁88都固定到下导向板50上可约束磁头86和磁铁88之间的相对振动或移动。 The read head 86 and the magnet 88 are fixed relative to the vibration or movement may be constrained between the head 86 and the magnet 88 on the lower guide plate 50. 另外还要注意,可将磁铁88刚性固定到圆形板90上,90上也固定读出磁头86。 Also note that the magnet 88 may be rigidly fixed to circular plate 90, 90 is also fixed on the read head 86.

为了把证券和读出磁头86之间的距离变化减至最小,要用键接到加速轴56上的路径约束轮62来限制读出磁头86上方的证券的路径。 In order to read the securities and the distance between the magnetic head 86 is minimized, to use the key on the acceleration path path constraint shaft 56 to limit wheel 62 above the read head 86 securities. 路径约束轮的表面在上导向板60的下方伸展以便在读出磁头86的附近形成一个很窄的间隙。 Path constraints wheel surface below the upper guide plate 60 extends to the vicinity of the read head 86 to form a narrow gap. 在路径约束轮62和读出磁头80之间形成的这个窄间隙能保证读出磁头86可基本上均匀地检测或扫描在读出磁头86上方通过的证券,准确地检测到可疑的伪券。 In this narrow gap 80 is formed between the wheel 62 and path constraints to ensure that the read heads read head 86 may be substantially uniformly detected or scanned in the read head 86 passing over securities, accurately detect suspect counterfeit notes. 路径约束轮62对证券进行均匀一致的磁检查,不会使卷边的证券产生堵塞卡住的现象,而这种情况在使用固定的路径约束部件完成类似功能的现有技术设备时是经常发生的。 Path constraints wheel 62 for securities uniform magnetic inspection, does not cause curling securities jamming of clogging, and this situation when using a fixed path constraint member prior art devices is to perform similar functions often of.

图4表示读出磁头86相对于光传感器80、82、84的位置。 Figure 4 shows the read head 86 relative to the position of the optical sensor 80, 82. 读出磁头86穿过位于下导向板50的一个位置的孔57凸出出来,该位置相对于证券传送方向(如箭头101所示)比光传感器80、82和84略微靠前一点。 The read head 86 passes through a hole located in the position 57 of the guide plate 50 protrudes out of position with respect to the conveying direction of securities (as indicated by arrow 101) than the light sensors 80, 82 and 84 slightly ahead. 一种有价证券(如用标号100总体表示的美元钞票)在箭头101所示方向沿下导向板50传送。 One kind of securities (such as a dollar bill generally indicated by reference numeral 100) in the direction indicated by arrow 101 along a lower transfer guide plate 50. 美元(如美元100)的特征是有非磁性的中央部分104和磁性的周边油墨部分102。 Dollars (e.g., $ 100) is characterized by a central non-magnetic portion 104 and a peripheral magnetic ink portion 102. 因此,当美元钞票100通过磁头86时,读出磁头86产生的感应电信号的特征就是有两个不规则强度的周期,它们代表美元钞票100的磁性油墨部分102的首、尾周边部分通过磁头86。 Thus, when the dollar bill 100 by the magnetic head 86, the read head 86 wherein the electrical signals produced is to have two periods of irregular strength, they represent magnetic ink 100 dollar bill header portion 102, the peripheral portion of the tail through the head 86.

由图5A所示的磁信号调节电路110对读出磁头86根据证券的通过情况产生的电信号进行处理。 Magnetic signals shown in FIG. 5A adjustment processing circuit 110 read out the electrical signals generated in accordance with the magnetic head 86 by the case of securities. 调节电路110完成几项信号处理功能,提取并放大来自读出磁头86的电信号的成分,使其成为适于模-数转换的形式。 Conditioning circuit 110 to complete several signal processing functions to extract and amplify the component of the electrical signal from the read head 86, making it suitable for analog - digital conversion of the form. 读出磁头85与拾取电路120连接。 The read head 85 and the pickup circuit 120 is connected. 拾取电路120产生一个拾取信号210,图5B表示出一个典型的拾取波形。 Pickup circuit 120 produces a pickup signal 210, FIG. 5B shows a typical pickup waveform. 拾取信号210主要为来自设备电源的60Hz、200mv峰-峰值的漏洩噪声。 Pickup apparatus 210 from the main power source of 60Hz, 200mv signal peak - peak leakage noise. 为使表示清楚,图中没有表示出由于振动来自电机的电噪声产生的信号210的噪声分量。 For clarity, not shown in FIG noise component from the electrical signal due to the vibration of the noise generated by the motor 210. 时间t1表示具有磁性油墨周边部分的证券的前缘开始在读出磁头86上通过的时间。 Time t1 represents the leading edge of the magnetic security portion of the periphery of the ink at the start time by the read head 86. 证券上的油墨图案使拾取信号210的低幅振荡的频率分量明显超过60Hz。 Security ink pattern on the frequency components of low amplitude oscillation pickup signal 210 is significantly more than 60Hz. 这种低幅振荡在证券的非磁性部分通过读出磁头86时暂时减小。 Such low amplitude oscillations in a non-magnetic portion securities temporarily decreases by the read head 86. 在证券的非磁性部分通过后,在拾取信号210中再次出现这种低幅振荡。 After the non-magnetic portion by securities, the pickup signal 210. This low amplitude oscillations again. 时间t3表示证券的尾缘通过读出磁头86并且低幅振荡停止的时间。 Time t3 indicates the time the trailing edge of securities by the read head 86 and the low-amplitude oscillation is stopped. 由证券的通过所引起的低幅振荡的频率分布明显低于振动噪声和电机噪声的频率范围。 A frequency low amplitude oscillation caused by the distribution of the securities significantly lower than the frequency range of vibration noise and motor noise. 现在回到图5A,拾取信号210加到前置放大级130,该放大级130将拾取信号放大到适于提取由证券的磁性油墨部分引起的低幅振荡的电平。 Returning now to Figure 5A, the pickup signal 210 is applied to a preamplification stage 130, amplifier stage 130 which amplifies the pickup signal to the low-amplitude oscillation caused by the magnetic adapted to extract part of the ink level of security. 经过前置放大的信号加到带通滤波器140。 After the pre-amplified signal to bandpass filter 140. 对带通滤波器的上、下半功率点频率进行选择,以基本上清除来自经过前置放大的信号的低频电源噪声和高频的振动和电机噪声。 Of the bandpass filter, the half-power frequency is selected to substantially remove vibration and motor noise from the preamplified signal after low-frequency and high-frequency power supply noise. 我们发现,从约250Hz到约1600Hz的通频带适合于此目的。 We found that the passband from about 250Hz to about 1600Hz suitable for this purpose. 带通滤波器140可以是串接一个高通级和一个低通级的两级放大器,或者是一个单级带通放大器。 Bandpass filter 140 may be connected in series a high-pass stage and a lowpass stage of two-stage amplifier, or a single stage bandpass amplifier.

一旦通过带通滤波器140提取出期望的频率范围,就将经过滤波的信号加到一个第二放大级150。 Once the band-pass filter 140 extracts the desired frequency range, the filtered signal will be applied to a second amplifier stage 150. 第二放大级150将经过滤波的信号放大到适合于模/数转换并最终适合于阀值估算的电平。 The second amplifier stage 150 amplifies the filtered signal is adapted to A / D conversion and finally adapted to the threshold level estimation. 第二放大级150最好既包括可变增益级154又包括固定增益级152。 Preferably both the second amplification stage 150 includes a variable gain stage 154 in turn comprises a fixed gain stage 152. 提供可变增益级154的目的是调节放大器150的增益以补偿拾取信号幅度的变化。 Purpose of providing a variable gain stage 154 is to adjust the gain of the amplifier 150 to compensate for changes in the pickup signal amplitude. 这种变化可能由设备操作速度的变化引起。 Such changes may be caused by a change speed device operation.

在已放大到适于数字转换的电平后,把经过放大的信号加到一个整流器160,整流器160对该放大的信号进行整流以使随后的积分能得到一个正值。 After having been amplified to a level suitable for digital conversion, the amplified signal is applied to a rectifier 160, the rectifier 160 rectifies the amplified signal so that subsequent integration to get a positive value. 然后,把整流过的信号加到一个积分器180,积分器180对该整流信号进行积分。 Then, the rectified signal is applied to an integrator 180, the integrator 180 integrates the rectified signal. 将该积分器设计成具有有限的积分时间。 The integrator is designed to have a finite integration time. 积分器180的积分时间有限将会降低调节电路110对于整流信号的瞬时涨落的灵敏度,因此从积分信号中采集的数字式取样就能得到代表在有限时间周期检测到的证券的磁特性或磁性质的取样值。 The integrator 180 is limited integration time adjustment circuit 110 will reduce the instantaneous fluctuations of the rectified signal sensitivity, the integrated signal collected from the sampled digital magnetic characteristics can be obtained for a limited period of time representative of the detected magnetic or securities the nature of the sample values. 积分器180的有限积分时间还能补偿由读出磁头86和光传感器80、82、84沿下导向板50的相对位置的摆动引起的、在磁检测和光检测之间的时间滞后。 Oscillating finite integration time of the integrator 180 is also compensated by the read head 86 and the optical sensor 80, 82 in the relative position of the guide plate 50 is caused, the time lag between the magnetic detection and optical detection. 由该积分器获得的另一个好处是积分信号在证券的非磁性部分出现在读出磁头86上的时间内不会跌落到零。 Another benefit obtained by the integrator is the integral signal appears at readout time not fall to zero on the non-magnetic part of the magnetic head 86 securities. 可接受的积分时间的上限由加到该设备的证券之间短暂间隔确定。 The upper limit of acceptable integration time is determined by the brief interval between the applied security device. 积分时间必须足够短以允许信号衰减,使相继的两个证券之间的积分信号幅度不致于拖得太长。 The integration time must be short enough to allow the signal attenuation, the successive two integrated signal amplitude between securities as not too long. 我们发现,2毫秒左右的积分时间适合于约1200个证券/分钟的证券计数速度。 We have found that the integration time of about 2 milliseconds to about 1200 for securities / min speed document counting.

图5B表示由积分器产生的积分信号,即调节信号220。 5B shows the integrated signal generated by the integrator, i.e., adjustment signal 220. 调节信号220的特征是有两个约4v的峰值,它们基本上是和一个证券的磁化周边部分在读出磁头86上通过时同时产生的。 Characterized in that the adjustment signal 220 has a peak approximately two 4v, which is substantially magnetized peripheral portion and a read-out of securities simultaneously generated when the magnetic head 86. 通过比较拾取信号210和调节信号220可以看出,在调节信号220中60Hz的电源噪声的影响减小到偶尔发生的尖峰信号的程度。 Pickup signal by comparing the adjustment signal 210 and 220 can be seen, the influence of adjusting the power supply noise of 60Hz signal 220 is reduced to the extent of occasional spikes. 通过调节信号220在大范围内的升、降,就可辨别出证券在读出磁头86上通过期间的t1和t3之间的时间间隔。 By adjusting the signal 220 liters in a wide range of drop, can be discerned on the head stock 86 read time period between t1 and t3 by interval. 证券在光传感器80、82和84上方的时间出现在t2和t4之间的时间间隔。 Securities at time 80, 82 and above the optical sensor 84 appears in the time interval between t2 and t4. 该光检测间隔稍稍落后于在t1和t3之间的磁检测间隔。 The photodetector spaced slightly behind the magnetic detection interval between t1 and t3. 积分器180的有限积分时间能确保:调节信号220一直有一个与光检测间隔同时发生的明显可靠的幅度。 Finite integration time of the integrator 180 ensures that: an adjustment signal 220 has a significant amplitude of a reliable optical detection interval simultaneously.

图5C表示调节电路110的一个详细示意电路图。 5C shows a detailed schematic circuit diagram of a regulating circuit 110. 电路110包括几个线性运算放大器级(最好由LM324运算放大器构成),以实现结合图5B所述的信号处理功能。 Circuit 110 includes several linear operational amplifier stages (preferably constituted by an operational amplifier LM324), to implement the signal processing functions in conjunction with FIG. 5B. 表1中列出了和调节电路110有关的优选元件数值。 Table 1 lists the component values ​​and conditioning circuitry 110 is preferably associated. 图5C所示的调节电路110的详细工作过程对本领域普通技术人员来说是显而易见的。 The detailed operation of FIG. 5C circuit 110 shown adjusted to those of ordinary skill in the art will be apparent. 为了进一步加强和电噪声源的隔离作用,把一个基准电压自一个虚地(如,一个TLE2425型虚地)加到带通滤波级142和144、放大级152和154、以及整流器160。 In order to further strengthen the electrical noise source and isolation, to a reference voltage from a virtual ground (e.g., a virtual ground type TLE2425) was added to the bandpass filter stage 142 and 144, amplifier stages 152 and 154, and a rectifier 160. 通过一个稳压器(如,拾取电路120中的LM7805型5伏直流稳压器)给读出磁头86提供偏置。 By providing a bias voltage regulator (e.g., the LM7805 type pickup circuit 5 volt DC voltage regulator 120) to the read head 86.

在t4检测间隔结束后,让累加的数值与一个或多个基准值进行比较,以验证该累加的数值是否对应于具有预定的或可接受的磁特性或磁性质的真证券的值。 At the end of the detection interval t4, so that the accumulated value with one or more reference values ​​are compared to verify whether the value of the accumulated value corresponding to a predetermined or acceptable magnetic properties or magnetic characteristics of genuine securities. 例如,该累加的数值可以和具有下阈值和上限值形式的基准值进行比较,该下阈值和上限值确定了可接受的累加值的一个范围,借此范围可辨别一个证券是否是可接受的或真正的证券。 For example, the accumulated value and the reference value may be compared with a lower threshold and an upper limit value in the form of the lower and upper threshold value determining a range of acceptable integrated value, whereby the range is discernible whether a security accepted or real securities. 下面,结合图7A-D更详细地描述一个程序,在该程序中结合证券处理设备的其它一些功能可以实现磁特性的核实检验。 Hereinafter, in conjunction with FIGS. 7A-D is described in more detail with a program, in conjunction with other security functions in the processing device may be implemented in program verify test magnetic properties.

已经发现,检验证券真实性的一个有益的方法是累加和证券的磁特性相对应的取样值,然后将一个有代表性的值与一个或多个基准值进行比较。 It has been found a useful method for testing the authenticity of the magnetic properties of securities and securities corresponding accumulated sample values, then a representative value of one or more reference values. 当被检验的证券具有足够强的磁性和/或具有按空间分布的磁性时,这一程序尤为有益,很容易把真券与可疑的伪券可靠地区别开来。 When the securities have been tested sufficiently strong magnetic and / or when a magnetic according to spatial distribution, this procedure is particularly useful, it is easy to suspect a genuine note and reliably distinguished from counterfeit notes. 和美国货币相比,准备检验的某些证券的磁性油墨部分可能相对来说局限在某一区域和/或磁特性较弱。 And the US currency compared ready to test certain magnetic ink part of the securities may be relatively limited to a certain area and / or magnetic properties of the weak. 例如,如图9所示,一张中华人民共和国发行的50元钞票350包括一个相当小的区域352,在区域352中有磁性相当强的油墨。 For example, as shown in FIG 9, a 50-dollar bills issued People's Republic of China 350 comprises a relatively small region 352, a very strong magnetic field 352 in the ink. 在50元钞票其余部分上的油墨的磁性相当弱。 Magnetic ink on the remaining portion 50 of dollar bills rather weak. 包含磁性相当强的油墨的区域352在靠近50元钞票350的背面底部中央。 Very strong magnetic ink comprises a region 352 near the center of the back bottom 50 yuan bill 350. 在50元钞票350的正面(未示出)还包括一个存在磁性相当强的油墨的一个限定的区域。 50 yuan bills face 350 (not shown) further includes a relatively strong magnetic ink a defined region is present. 此外,在这种50元钞票上使用的磁性油墨的磁性比美国货币上使用的磁性油墨的磁性低。 Further, the magnetic magnetic magnetic ink on such magnetic ink 50 yuan banknotes used than using U.S. currency low. 50元钞票上的油墨的磁性减小的实际结果是:由如结合图5A-C所述的信号调节电路110给出的响应值比处理美国货币所得的响应值低。 Magnetic ink on the bill $ 50 is reduced actual results: adjusting the signal as described in connection FIGS. 5A-C the response value is lower than a given circuit 110 processing the resulting monetary U.S. response. 因此,由检测真50元钞票的磁性所得到的电信号不可能与在50元伪钞通过该计数设备时检测到的电噪声可靠地区分开。 Thus, separate electrical noise detected by the magnetic true 50 yuan banknotes are not possible to detect the electrical signal obtained when the 50 yuan banknotes reliably by the counting device.

为了按照磁特性可靠地检验证券,如50元钞票,在该设备中最好使用一个强化的磁检测和调节系统,该系统的增益较高并且相对于电路110的噪声有较小的灵敏度。 In order to reliably test according to the magnetic characteristics of securities, such as 50-dollar bills, it is preferable to use a magnetic detection and control system in the apparatus enhanced, the gain of the system is high and the circuit 110 to noise have less sensitivity. 图10A和10B示意地表示出这样一个强化的检测和调节系统,该系统包括读出磁头360和调节电路110a。 10A and 10B schematically shows such an enhanced detection and regulation system, the system comprising a read head 360 and the adjusting circuit 110a. 在表2中列出了涉及调节电路110a的优选元件值。 Table 2 lists the preferred element values ​​relate to adjusting circuit 110a.

C3-.1μF IC1-LM324R4-75KΩ IC2-MAX680R5-150KΩR6-47KΩR7-100KΩR8 -3KΩ read head 360 is mounted on the processing device, which installation and 3A reads out the binding of the magnetic head 86 mounting the same. 读出磁头360与图10B所示的直流电源相连,并且根据磁性证券的通过状态在线362上提供拾取信号。 Reading out the DC power supply 360 shown in FIG. 10B is connected to the magnetic head, and provided on the pick-up signal line 362 via a state according to a magnetic securities. 读出磁头360最好是磁阻传感器,例如由MurataErie North America of Smyrna,Georgia制造的型号为BS05NIHGAA的货币识别传感器。 The read head 360 is preferably a magnetoresistive sensor, for example, a North model MurataErie America of Smyrna, Georgia manufactured BS05NIHGAA of currency recognition sensor. 读出磁头360不需要像先前结合永久磁铁88所述的那样在证券导向路径中加上外部磁场。 The read head 360 as the external magnetic field does not need to add in the securities previously in connection with the guide path as the permanent magnet 88. 由于不需要单独的磁铁(如,磁铁88),所以根除了在读出磁头360和这样一种磁铁之间的相对振动的影响。 Since the need for a separate magnet (e.g., magnet 88), so the effect of eradication of relative vibration between the head 360 and a magnetic readout.

为了进一步减小电噪声的影响,信号调节电路110a在设备中的安装位置要远离读出磁头360并且远离电机321。 To further reduce the effect of electrical noise, the signal conditioning circuit 110a in the device away from the mounting position of the read head 360 and 321 away from the motor. 加到线362的电信号通过屏蔽电缆364加到设备远端的信号调节电路110a。 Electrical signal on line 362 applied to the distal end 364 of the signal conditioning circuit device 110a via a shielded cable. 来自线362的拾取信号电容耦合到调节电路110a,并由调节电路中的固定增益放大器366接收。 Pickup signal from line 362 is capacitively coupled to the adjusting circuit 110a, by the regulation circuit 366 receives the fixed-gain amplifier. 放大器366最好包括一个LM324型运算放大器,该放大器与图10B所示的双极性10伏直流电源电路369相连。 Amplifier 366 preferably includes a LM324 op amp, 10 volt DC is connected to a bipolar power supply of the amplifier circuit shown in FIG 10B 369. 该电源电路368最好包括由MaximIntegrated Products of Sunnyvale,California制造的型号为MAX680DC/DC的电荷泵转换器。 The power supply circuit 368 preferably comprises a model MaximIntegrated Products of Sunnyvale, California manufactured by MAX680DC / DC converter of a charge pump. 双极性10伏电源如图所示与放大器366相连,并且与信号调节电路110a中的其它元件相连,因此和调节电路110中使用单端电源的比较电路(如图5A所示)相比,放大器366依据拾取信号可提供较大的电压变化。 Bipolar 10-volt power amplifier 366 connected as shown in FIG, and other elements of circuit 110a is connected to the signal conditioning, thus regulating circuit 110 and the comparator circuit using a single power supply (FIG. 5A) as compared pick-up signal amplifier 366 may be provided according to a larger voltage change. 用5伏的直流信号可以很方便地操作双极性直流电源369,而5.伏的直流信号是和该处理设备中其它地方使用的逻辑电路兼容的。 5 volt DC signal can easily operate the bipolar DC power source 369, and a 5 volt DC signal processing device and the logic circuit using compatible elsewhere.

由放大器366依据拾取信号产生的放大信号电容耦合到可变增益放大器368的输入端。 Amplifying the signal picked up by the capacitive coupling amplifier 366 according to the signal generated by the variable gain amplifier to an input terminal 368. 可变增益放大器368最好包括一个用于调节放大器368的增益的电位器R3,对从具有不同磁性的证券来的信号进行补偿。 The variable gain amplifier 368 preferably includes a gain amplifier 368 for adjusting potentiometer R3, the signal coming from the securities having different magnetic compensate. 例如,可调节电位器R3,使放大器368的增益值相当低,用于处理美国的货币。 For example, an adjustable potentiometer R3, the value of the gain of the amplifier 368 is very low, for processing U.S. currency. 为了处理磁特性相当弱的中国货币或其它证券,可调节电位器R3,使该增益值相当高。 To process relatively weak magnetic properties Chinese currency or other securities, adjustable potentiometer R3, so that the gain value is quite high. 在本发明的实践中可以使用调节放大器368的增益的其它装置(如,增益选择开关装置),为用户提供使信号调节电路110a可适应于要处理的证券的各种特定类型磁特性的能力。 In the practice of the present invention may use other means for adjusting the gain of the amplifier 368 (e.g., gain selecting switch means), to provide users with a signal conditioning circuitry 110a may be adapted to the capabilities of a particular type magnetic characteristics of the securities to be processed.

可变增益放大器368的输出信号加到高通滤波器370的输入端,高通滤波器370除去放大信号中低于预定频率(如低于300Hz)的频率分量。 The output signal of the variable gain amplifier 368 is applied to the input of the high pass filter 370, high pass filter 370 to remove the amplified signal frequency components below a predetermined frequency (e.g., less than 300Hz) of. 将来自滤波器370的经过滤波的信号电容耦合到一个组合在一起的整流器/积分器372。 Rectifier capacitively coupled through the filter from the filtered signal to a combined 370 / integrator 372. 整流器/积分器372对经过滤波的信号进行整流和积分。 A rectifier / integrator 372 pairs of rectifying the filtered signal, and integration. 整流器/积分器372的工作过程和先前结合电路110的整流器160和积分器180的工作过程类似。 A rectifier / integrator 372 of the working process and working process previously incorporated rectifier circuit 110 and 160 of the integrator 180 is similar.

由于调节电路110a有几级包括与双极性10伏电源相连的运算放大器,所以在该调节电路110a中在响应异常强的磁特性或响应瞬变信号时有可能产生高达10伏的信号。 Since there is likely adjusting circuit 110a includes an operational amplifier with a bipolar 10 volt power supply is connected, so that the adjusting circuit 110a in response to a strong magnetic properties or abnormal transient response signal to generate a signal up to a few stage 10 volts. 期望能把信号调节电路产生的调节信号限幅到10伏以下的电平,以使该调节信号能与该设备中其它地方的逻辑电路所用的较低电压兼容。 Desired signal conditioning circuit can adjust the level of the signal generated by the limiter 10 volts or less, so that the conditioned signal compatible with the device elsewhere lower voltage logic circuits used. 为了限制信号调节电路110a的输出端376提供的电压,在整流器/积分器372和输出端376之间连接一个削波电路374,以限制经整流和积分的信号。 In order to limit the voltage output of the signal conditioning circuit 110a to 376 provided, connected between the rectifier / integrator 372 and output terminal 376 a clipping circuit 374 to limit the rectified and integrated signal. 削波电路最好包括连在输出端376和地之间的一个齐纳二极管D2。 Preferably comprises a clipping circuit connected between an output terminal 376 and the zener diode D2. 对齐纳二极管进行选择,以便把在输出端376可得到的电压限制到与接收来自输出端376的调节信号的A/D转换器的基准电平相兼容的电平,如3.8伏或其它的期望电压值。 Zener diode is selected so as to limit the adjustment to the reception signal output from the A to D converter 376 of the reference level compatible level / voltage at the output 376 available, such as 3.8 volts or other desirable Voltage value. 在整流器/积分器和齐纳二极管D2之间串接一个电阻器R1,以便把流入二极管D2内的电流限制到一个适当的数值。 Between the rectifier / integrator and the zener diode D2 connected in series a resistor R1, so that the current flowing into the diode D2 is limited to an appropriate value.

现在参照图11,其中所示的各种电压波形代表由读出磁头360产生的拾取信号378、由高通滤波器370产生的经过滤波的信号380、以及在输出端376接收到的调节信号382。 Referring now to FIG. 11, the pickup signal 378 representative of various voltage waveforms where indicated by the read head 360 to produce, after filtering by a high-pass filter 370 to produce signal 380, and an adjustment signal 382 at the output 376 is received. 这些信号代表证券(如,50元钞票)沿证券导向路径通过时产生的信号。 These signals representative of securities (e.g., 50 bills) along a guide path securities generated when signal. 为清晰起见,在图11所示的波形中没有画出在一般情况下存在于这些波形中的噪声分量。 For clarity, in the waveform shown in FIG. 11 is not shown in the general case the noise component is present in these waveforms. 时间t1表示在导向路径中用中央光检测器检测证券的引导缘的时间。 Time t1 represents the time the leading edge in the guide path with the center of the light detector securities. 在时间t1,由读出磁头360产生的拾取信号378由于磁头与处理设备的交流电源偶合而暂时略有变化。 At time t1, the pickup signal produced by the read head 360 378 since the AC coupling head and processing apparatus is temporarily slightly changed. 高通滤波器370有效地阻挡了交流电源的60Hz频率,因此经过滤波的信号380和经过调节的信号382在时间t1基本上是平直的。 High-pass filter 370 effectively block the 60Hz frequency of the AC power supply, and therefore the filtered signal 380 and the adjusted signal 382 at time t1 is substantially flat.

当证券沿导向路径继续前进时,磁性油墨部分通过读出磁头360,使拾取信号378产生幅度约为200μv峰-峰值的几个高频振荡。 When securities move along a guide path, a magnetic read head by the ink portion 360, the pickup 378 generates a signal peak amplitude of about 200μv - Several high frequency oscillation peaks. 该高频振荡由放大器366和368放大并加到高通滤波器370,由此产生具有幅度约为1伏峰-峰值振荡的信号380。 The oscillation frequency applied to high-pass filter and amplified by the amplifiers 366 and 368 370, thereby generating a peak having an amplitude of approximately 1 volt - 380 oscillation signal peaks. 该信号380的振荡再经整流、积分,在从时间t2至时间t3的间隔期间产生幅度约为2伏的调节信号382的一个持续脉冲。 The oscillation signal 380 is then rectified, integrated, is generated from the amplitude during an interval of time t2 to time t3 is about 2 volts adjustment signal 382 of a sustain pulse. 时间t3之后,证券的磁性油墨部分已通过读出磁头360,因此波形378、380和382没有明显的持续脉冲。 After time t3, the magnetic ink has some securities by the read heads 360, 378, 380 and 382 and therefore the waveform of sustain pulses is not significant. 在时间t4,证券的尾缘通过中央光检测器,因此获得了证券检测间隔。 At time t4, the trailing edge through the central securities photodetector, thus obtaining the document detection interval.

按照结合信号处理电路110所述的方法,可以使用信号调节电路110a来检验证券。 The method 110 in conjunction with the signal processing circuit may be used to test the signal conditioning circuit 110a securities. 另一方面,在下面描述的另一种方法的实践中也可以使用电路110a。 On the other hand, in the practice of another method described below may also be used in circuits 110a.

由图11可见,在调节信号382有一个持续脉冲时期的时间t2和时间t3之间的间隔若和光检测器检测证券的整个检测间隔t1-t4相比是比较短暂的。 Seen from FIG. 11, the adjustment signal 382 if there is an interval between t3 and the light detector securities entire detection interval t1-t4 is relatively short compared to the time t2 and time period of a sustain pulse. 在时间t2和时间t3之间的调节信号382中的持续脉冲的相对短暂的性质为真证券通过期间通过取样该信号382并对取样的值求和而得到的累加值的范围规定了一个上限。 In the relatively brief nature of the adjustment signal 382 between time t2 and time t3, the sustain pulses is true securities by the sampling period obtained by sampling the signal 382 and the value of the accumulated value sum of a predetermined upper limit range. 累加值的这个限定的范围对可靠区分真、伪证券的能力又产生了不利的影响。 The accumulated value of the limited range of reliable distinguish true pseudo ability securities and adversely affected. 此外,和这样的证券的通过状态相关的波形中的持续脉冲幅度的间隔相当短暂,这就使取样值的累加对虚假信号的影响更加敏感,这是相对于处理具有较强和/或较大的磁性油墨部分的证券而言的。 Further, the pulse amplitude and duration of such a state by the securities-related waveform rather brief intervals, which makes the influence of spurious signals on the accumulated value is more sensitive to sampling, which is treated with a strong relative to and / or greater Securities magnetic ink part of the terms. 例如,如图11所示,对于拾取信号382,在检测间隔的时间t5处发生一个噪声尖峰信号。 For example, as shown in 382, ​​a noise spike occurs at the pick-up signal 11 to the time t5 detection intervals. 在调节信号382中的在时间t5处由尖峰信号引起的最终脉冲可能会对波形382的取样值的累加和的值产生明显的影响,这些取样值是在沿图11的下时间轴上的用多个小竖杠表示的取样间隔得到的。 Have a significant impact on the accumulated value and adjust the final pulse at time t5 caused by the spikes 382 may have a signal waveform sample value 382, ​​which is used in sampling values ​​along the axis 11 sampling interval multiple small vertical bar represents obtained.

为克服前述的检验具有弱磁性和/或高度局限的磁性的证券方面的困难,可以使用检验证券的另一种方法,其中的计数是根据调节信号382的短暂特性累加的。 To overcome the foregoing difficulties and weakly magnetic test securities and / or highly localized magnetic, another method may be used in security inspection, where the count is accumulated in accordance with the adjustment signal 382 transient characteristic. 按这种方法,对检测间隔调节电路110a的调节信号超过预定的下阈值VL的那些相继的取样间隔进行计数,从而得到一个计数值(或累加值)。 Those successive sampling interval adjustment signal according to this method, the detection interval adjustment circuit 110a exceeds a predetermined lower threshold VL is counted to obtain a count value (or integrated value). 然后,在一个调节信号的脉冲部分的持续期间将累加的计数同与真证券对应的一个或多个基准值进行比较。 Then, compared with a real security or more reference values ​​corresponding to an adjustment in the accumulated count of the pulse duration of the same portion of the signal.

检验证券的最后这种方法最好包括对调节电路110a的输出信号的取样值超过上限VH的取样间隔进行计数累加的步骤。 Finally, this method preferably comprises the step of examining the security of the accumulated count of sampled values ​​exceeding the upper limit VH of the sampling interval of the output signal conditioning circuit 110a is performed. 为了标识真证券的计数,大于VH的取样值的计数必须小于预定的最大基准值,并且大于VL的相继取样值的计数必须大于预定的最小基准值。 To identify true security count, the count value is greater than VH sample must be less than the predetermined maximum reference value, and greater than the count of consecutive sampled values ​​VL must be greater than a predetermined minimum reference value. 下面结合图7E的逻辑流程图描述实现这个方法的方式以及将该方法与证券处理设备的其它功能组合的方式。 The following description of the logic flow diagram of FIG. 7E implementation of this method and the way the methods and other security functions combined binding processing apparatus. 控制网络通过图6A所示的控制网络301来监测和控制计数和分选设备的操作。 Control network monitors and controls the operation of counting and sorting apparatus by the control network 301 shown in FIG. 6A. 微处理器(如,CPU 302)执行存贮在一个非易失存贮器(如,ROM 318)中的控制程序。 A microprocessor (e.g., CPU 302) is stored in a nonvolatile memory performed (e.g., ROM 318) control program. 控制程序协调下述功能:计数、分选、证券检验、电机控制、显示控制、用户输入、和与外部设备的通信。 A control program to coordinate the following functions: counting, sorting, inspection securities, motor control, display control, user input, and communication with external devices.

程序自228步前进至230步,用于累加证券检验数据的RAM 319的几个寄存器复位。 The program proceeds from step 228 to step 230, security testing for accumulating several data RAM 319 register is reset. 在每个证券通过期间,在RAM 319的相应寄存器中累加左、右传感器信号的操作总数、磁信号调节电路的输出、以及检测到的中断脉冲的数目。 During the passage in the respective left and accumulating register in RAM 319 in each of the securities, the total number of the operation right sensor signals, the magnetic signal conditioning circuit output, and the number of detected interrupt pulses. 在230步,复位每个证券通过期间在这些寄存器中存贮的总数。 In step 230, the total number of the reset period by each securities stored in these registers.

程序自230步前进至232步,按照和中央传感器80对应约A/D通道的值检测证券的存在状态。 The program proceeds from step 230 to step 232, and the center sensor 80 according to the present state corresponding to about A / D channel value detected securities. 如果中央传感器信号值低于预定的检测阈值,则控制过程分支到234步,等待来自定时轮的中断脉冲。 If the center sensor signal value is below a predetermined detection threshold, then control branches to step 234, waiting for an interrupt pulse from the timing wheel. 当在234步收到一个中断脉冲时,则控制过程继续前进到236,使空闲计数加1。 In step 234, when an interrupt pulse is received, control proceeds to 236, so that the idle count is incremented. 然后,在238步,该空闲计数与一个预定的限值比较。 Then, in step 238, the idle count comparator with a predetermined limit. 若在238步空闲计数不超过该限值,则控制过程返回到232步。 If in step 238 the idle count does not exceed the limit value, then control returns to step 232. 若在238步空闲计数的确超过了空闲限值,则控制前进到268,使该设备中止操作,然后又前进到270步,控制过程继续等待输入。 If in step 238 the idle count does exceed the idle limit, then control proceeds to 268, so that the device halts operation, and then proceeds to step 270, control continues waiting for input. 从270步开始,该控制过程可能要分支,在收到继续启动命令时分支到226步,或者在检测到放入斗仓中的证券时分支到228步。 Starting from step 270, the control procedure may branch to branch to step 226 upon receipt of a start command to continue, or is detected when placed in branches to step 228 in hopper securities. 一般而论,从270步开始的控制路径取决于引导到270步的状态条件和用户采取的动作的性质、或由外部设备的输入。 Generally speaking, the control path from step 270 are dependent upon the nature of the guide step 270 the user state condition and actions to be taken, or by an external input device.

如果在232步中央证券传感器的确寄存了一张证券的存在状态,则控制过程前进至图7B的233步(用廷续标记B表示)。 If at step 232 the central securities sensor does register the presence of a security state, the control process proceeds to step 233 of FIG. 7B (with the mark B denotes ting Continued). 在233步,检验两个条件以确定电机是否应该停止。 In step 233, two test conditions to determine whether the motor should stop. 第一个条件是叠放计数是否已达到表示少于一张证券的整叠放盒的数值。 The first condition is whether or not the count has reached the stacking represents an integer value less than a securities stacked cassette. 由于设备操作速度很高,所以证券传送机构不可能马上停下来。 Due to the high operating speed of the device, the securities transfer mechanism can not immediately stop. 因此,如果叠放盒将要放满,则必须在检测到每张证券的首缘时作出这样的决定。 Therefore, if the stacked boxes to be filled, it must make that decision when it detects the first edge of each document. 类似地,如果设备按分批方式运行,则在233步要确定由中央传感器目前正检测到的证券是否是一批证券中的最后一张证券。 Similarly, if the device is running in a batch mode, then in step 233 to determine whether the sensor is currently being detected by the central securities are a number of securities in the last securities. 如果满足这两个条件中的一个条件,则控制过程前进至235步,在235步中电机控制电路开始使用公知的制动技术关断电机。 If a condition of these two conditions is satisfied, the control process proceeds to step 235, in step 235 the control circuit starts the motor using well known techniques will be cut off the brake. 当电机控制电路开始制动电机时,或者在233步中条件都不满足时,控制过程前进至240步。 When the motor control circuit starts to brake the motor, or when the conditions are not met in step 233, control proceeds to step 240.

240步是数据累加循环200的第一个步骤,在此期间当每个证券通过该设备时都产生传感器数据的操作总数。 Step 240 is the data accumulation loop 200 is a first step, during which the securities are generated when the total number of actions for each sensor data through the apparatus.

当在240步检测到一个中断脉冲时,控制过程转至242步,使证券长度计数加1。 When the step 240 detects an interrupt pulse, the control procedure advances to step 242, that the document length count is incremented. 控制过程从242步转到244步。 Control procedure from step 242 to step 244. 在244步,检查表示先前已检测到一张证券的右传感器的标志。 In step 244, check represents the previous mark of a security right sensor has been detected. 在数据累加循环200的第一迭代操作期间,右标志还未设定,控制前进至246步。 During operation of the first iteration of the data accumulation loop 200, the right flag has not been set, control proceeds to step 246. 在246步,查询和该右传感器信号对应的那个A/D通道,以便确定沿下导向板50的右侧的证券存在状态。 In step 246, the query and the right sensor signal corresponding to the A / D channel, the right to determine the presence status of the securities along lower guide plate 50. 如果检测到一张证券,则控制过程前进到248步,在248步使右传感器标志置位,并且按照在226步选择的遮光性大小通过LED控制电路306确定右LED的亮度,控制过程前进至252步。 If it detects a security, control proceeds to step 248, at step 248 that the right sensor flag is set, and light shielding properties, in accordance with step 226 determines that the right choice of the LED 306 through the LED brightness control circuit, the control process proceeds to 252 steps. 如果在246步沿下导向板50的右侧没有检测到证券,则控制过程直接前进至252步,右LED依然保持在证券检测时的亮度大小。 If the lower right side along the guide plate 50 is not detected at step 246 the securities, the control process proceeds directly to step 252, the right LED remains at the document detection brightness of size. 在证券数据累加循环200期间若左传感器标志或右传感器标志没有置位,则发生证券的宽度偏离检测。 During the data accumulation loop 200 securities if the left sensor flag or right sensor flag is not set, the width of the securities deviation detection occurs. 一旦在248步右传感器标志置位,则随后执行的244步将控制过程分支到250步。 In step 248, once the right sensor flag is set, step 244 is then executed to control the process branches to step 250. 在250步,取样和该右传感器对应的那个A/D通道并累加在RAM 319的一个寄存器中,并且控制过程转至252步。 In step 250, the sampling and the right sensor corresponding to the A / D channel and accumulated in the RAM 319 in a register, and the control procedure advances to step 252. 在250步A/D转换器从右传感器取的遮光性数据的变化范围一般都相当小。 In step 250 A / D converter from the right sensor taken shielding range of the data is generally quite small. 为了清楚地刻划正常的证券和遮光较多的证券(如一个双层的证券),最好把遮光性数据粗略地量化成几个宽的范围,对这些范围进行数字加权,以减小小范围遮光性变化的影响。 To clearly scored normal securities and the light-shielding more securities (such as a bilayer securities), the light-shielding data is preferably coarsely quantized into a few broad ranges, these ranges for digitally weighting, to reduce the small the impact of changes in the scope of shading. 只使用4级遮光性数据量化就足以完成单个证券和双重证券之间的鉴别。 Shielding only four quantized data is sufficient to complete the discrimination between single and double securities securities.

从252步开始,对左证券检测器执行和在244-250步中对右检测器执行的确定步骤相类似的确定步骤。 From the start step 252, left and securities detector performs the determination of steps 244-250 in the right detection step similar to the step of determining phase. 如果在252步发现左标志已被置位,则控制过程转到258步,在258步对左传感器的信号大小进行测量、量化和累加。 If in step 252 the left flag has been set, control transfers to step 258, the measurement of the size of the left sensor signal in step 258, quantization and accumulation. 若在252步发现左标记没有置位,则控制过程前进到254步。 If the left flag is not found in step 252 is set, the control process proceeds to step 254. 在254步,对左传感器取样,并且和一个阈值比较以确定在导向板的左侧是否存在一个证券。 In step 254, the left sensor for sampling, and comparing with a threshold value to determine whether there is a stock of the left side of the guide plate. 若在254步检测到一个证券,则控制过程前进至256步,使左标志置位。 If the step 254 detects a security, control proceeds to step 256, the left flag. 在256步CPU 302还要向LED控制电路306发出一个信号,以便将左LED 83的亮度提高到在226步选定的遮光性检测的水平。 CPU 302 also in step 256 to the LED control circuit 306 sends a signal to increase the brightness of the left LED 83 to a selected level at step 226 the light shielding detection. 控制过程从256步转至260步。 The control procedure advances to step 260 from step 256. 若在254步在左光传感器没有检测到证券,则控制过程直接转至260步。 In step 254, if security is not detected in the left light sensor, the control process goes directly to step 260.

在260步,对和磁信号调节电路110的输出对应的A/D通道进行取样和累加。 In step 260, the output of the signal conditioning and the magnetic circuit 110 corresponding to the A / D sampling and accumulating channel. 然后,控制过程转到262步,在262步再次对中央传感器的A/D通道进行取样,以确定证券的存在状态。 Then, control transfers to step 262, again on the center of the sensor A / D channel is sampled at step 262, to determine the presence status of the securities. 如果中央检测器还检测到一个证券,则控制过程返回到240步,继续进行数据累加循环200。 If the central detector further detects a stock, then control returns to step 240 to continue the data accumulation loop 200. 当在262步没有检测到一个证券时,则结束该数据累加循环200,控制过程分支到263步,开始进行如图7C所示的控制过程的数据评估阶段,如由接续标记C所表示的。 When step 262 does not detect a security, the end of the data accumulation loop 200, the control procedure branches to step 263 to begin a data evaluation phase of the control process shown in Fig. 7C, the connecting symbol C as indicated.

从263步开始,按照数据累加期间累加的数据进行一系列检验中的第一项检验。 Starting step 263, a series of tests performed in accordance with the first test data accumulated during the data accumulation. 值得注意的是,除图7B所示的程序外还可按其它的逻辑程序进行数据评估检验。 It is noted that also in other test data evaluation logic program in addition to the routine shown in FIG. 7B. 在263步,将数据累加循环200期间达到的长度计数和长度阈值进行比较。 In step 263, the data accumulated during the cycle reached 200 length count and length threshold value. 若长度数值小于阈值,则控制过程前进到265步,在265步中经显示器16向用户显示“半”误差。 If the length is less than the threshold value, the control process proceeds to step 265, display "half" error to the user via the display 16 in step 265. 从278步开始,控制过程如接续标记D2所示转到图7D所示的267步,复位运行计数;然后前进到269步停止电机。 Starting from step 278, control as shown in FIG subsequent to marking step shown D2 7D 267, the run count is reset; and then proceeds to step 269 to stop the motor. 之后在271步,控制过程等待来自叠放盒光传感器的表示已从叠放盒排空了证券的信号。 After step 271, control waits expressed from a stacked cassette stacked from the light sensor signal emptied cartridge securities. 若在图7C的263步长度计数超过了下阈值,则控制过程前进至264步。 If Step 263 in FIG. 7C length count exceeds the lower threshold value, the control process proceeds to step 264.

在264步,将数据累加循环200期间取的长度计数与一个长度上限值进行比较。 In step 264, the length of a length count taken during the data accumulation loop 200 is compared limits. 若长度计数超过了长度上限值,则由显示器显示表示粘连误差的信息,和/或将该信息在266步输出到RS-232端口。 If the length count exceeds the upper limit value of the length, by blocking the display displays information indicating that an error, and / or outputs the information to the RS-232 port in step 266. 从266步开始,控制过程如接续标记D2所示转至图7D所示的267步,在267步复位运行计数。 From the start step 266, the control procedure as shown in FIG splicing mark D2 7D 267 go further illustrated, step 267 resets the run count. 然后前进到269步,停止电机。 And then proceeds to step 269, stop the motor. 然后在271步,控制程序等待来自叠放盒光传感器的表示已从叠放盒排空了证券的信号。 Then in step 271, the control program waits for a stacked cell light sensor indicates cartridge emptying superposed signal from securities. 若在图7C的264步长度计数没有超过长度上限值,则控制过程前进至272步,在272步按照一个预定的适应性因子修改长度阈值和上限值。 If the length count in step 264 of FIG. 7C is not longer than the upper limit value, the control process proceeds to step 272, change the length threshold and upper limit value according to a predetermined adaptation factor in step 272. 最好对于每一种证券都调节长度的上、下限,以便按一个预定的比例将最近测量到的证券的长度归类在一起。 It is preferably adjusted for each security on the length of the lower limit, according to a predetermined ratio of the measured length to the nearest securities grouped together. 长度上、下限的这种比例适应性使该设备能连续适应电机速度的变化以及证券长度的微小变化。 Length, the lower limit of this ratio so that the apparatus can adaptively change and continuously adapt to small changes in the length of the securities motor speed.

在272步修改了证券长度限值后,用长度计数除累加的磁数据,从而在274步产生一个平均的磁检验值。 After the document length limits modified in step 272, the count accumulated magnetic data except the length to produce an average magnetic test value in step 274. 然后,评估程序前进到276步,在276步检查右标志。 Then, the program proceeds to the evaluation step 276, the right flag is checked at step 276. 若在数据累加循环200期间右标志没有置位,则程序前进到278步,在278步通过适当的显示向用户通告证券宽度偏离误差。 If the data accumulation loop 200 during the right flag is not set, the routine proceeds to step 278, at step 278 by an appropriate width to display to the user CircularsSecurities out errors. 从278步开始,控制过程如接续标记D2所示转到图7D的267步,在267步复位运行计数,然后转到269步,在269步停止电机。 Starting from step 278, the control procedure as shown in connection flag D2 to step 267 of FIG. 7D, the counting operation is reset in step 267, then go to step 269, the motor is stopped at step 269. 然后在271步,控制过程等待来自叠放盒光传感器表示已从叠放盒排空了证券的信号。 Then in step 271, control waits for stacking boxes stacked from the photosensor indicates cartridge emptying signal securities. 若在图7C的276步发现右标志已置位,则该程序开始在280步检查左标志,若发现左标志没有置位则有类似的结果。 If the right flag is found set, the program starts to check the left flag in step 280, if the left flag is found not set, the result is similar. In step 276 of FIG. 7C 若左标志置位,则控制过程前进到282步。 If the left flag is set, the control proceeds to step 282.

在282步,将左、右遮光性数据累加寄存器中的内容与在226步确定的它们的相应的阈值进行比较。 In step 282, the left and right shielding accumulation data register contents are compared with their respective threshold values ​​determined in step 226. 如果每个遮光性数据累加寄存器的计数都超过相应的阈值,则在284步通告用户存在一个误差,如一个双重误差。 If each light-shielding count data accumulation registers exceeds the respective threshold values ​​are, then at step 284 an error announcement user exists, such as a double error. 从284步开始,控制过程如用接续标记D2所示转至图7D的267步,在267步复位运行计数,然后转至269步,在269步停止电机。 From the start step 284, the control procedure with splicing mark 267 as shown in Step D2 Turning to FIG. 7D, the run count is reset in step 267, then go to step 269, the motor is stopped at step 269. 然后在271步,控制过程等待来自叠放盒光传感器表示证券已从叠放盒排空的信号。 Then in step 271, control waits for stacking boxes stacked from the photosensor signal represents securities cartridge emptying. 若在图7C的282步,和累加遮光性数据的寄存器有关的计数小于相应的阈值,或者如果在226步禁止双重检测,则控制过程如接续标记D1所示前进到图7D的286步。 If in step 282 of FIG. 7C, light-blocking and accumulation data related to the corresponding count register is less than the threshold value, or if double detection is prohibited in step 226, the control process steps as splicing numeral 286 proceeds to FIG. 7D D1.

在286步,评估程序确定是否允许进行可疑伪券检验(CFS)。 In step 286, the program determines whether to allow assessment of suspected counterfeit note testing (CFS). 若允许CFS检测,则控制过程前进至288步。 If CFS detection allowed, control proceeds to step 288. 在288步,将在274步确定的磁检验平均值与一个预定的阈值进行比较。 In step 288, comparing the average magnetic test determined in step 274 with a predetermined threshold value. 若磁检验平均值不大于预定的阈值,则在290步向用户提供可疑伪券误差显示,并且停止电机。 If the magnetic inspection average less than a predetermined threshold value, then at 290 the user to provide moving towards suspected bogus error display, and stops the motor. 由于证券传送机构不可能立即停止,因此当在290步停止电机时可疑的伪券和输入叠放中的下一个证券(如果有的话)都被传送到叠放盒。 Since the securities can not immediately stop transmitting mechanism, so that when the motor is stopped at step 290 and the input suspected counterfeit notes in the next stack of securities (if any) are transmitted to the stacked boxes. 控制过程然后转至291步,在291步,从叠放盒取出可疑伪券和下一张证券、把下一张证券放回斗仓、并按下继续键,从而恢复了正常操作。 Process control then go to step 291, in step 291, remove the suspected counterfeit notes and securities from a lower stacked cassette, back into the hopper at a securities, and continue to press the key, thereby restoring normal operation. 在291步按下继续键后,控制过程返回到如接续标记A所示的图7A的228步,因此绕开了对传送到叠放板的可疑伪券或随后的这张证券的计数操作。 After the step 291 continues to press the key, control returns to the splicer A numeral 228 in FIG. 7A step, thus bypassing the counting operation of suspected counterfeit notes transferred to the stacking plate or this subsequent securities.

若在286步发现CFS检测被禁止,或者若在288步发现超过了CFS阈值,则控制过程前进至292步。 If it is found CFS detection is disabled, or if found to exceed the threshold CFS step 288, control proceeds to step 292 in step 286.

在292步,使运行记数和叠放计数加1。 In step 292 the run count and stack count by one. 使用叠放计数来保证不超过叠放盒容量。 Use stacking count not to exceed the capacity of the stacked boxes. 一旦从叠放盒排除了叠置的证券,叠放计数就要复位。 Once stacked securities excluded from the stacked boxes, stacking will reset the count. 运行计数是从最近一次执行图7A的226步开始已经检测到的证券数目。 The run count from the last performed step 226 in FIG. 7A start number of securities has been detected.

当从292步前进到294步时,如果该设备被设定为按分选方式运行,则分支到296步。 When proceeds from step 292 to step 294, if the apparatus is set to run in the sorting mode, branches to step 296. 若在296步证券计数已经达到规定的批量大小,则在298步向用户提供完成一个批量的显示。 If in step 296 the security count has reached the predetermined batch size, then at 298 the user to provide moving towards completion of a batch display. 因为在达到298步前已经在233步检测到该批证券即将完成,所以电机已充分慢下来,因此现行的证券就是传送到叠放板的最后一个证券。 Because before reaching the step 298 has been detected in a batch of securities nearing completion step 233, the motor has been sufficiently slow down, so the existing securities is transferred to a securities last stacked plates. 控制过程从298步继续前进到271步,并等待从叠放板排空这批证券。 Control proceeds from step 298 the process continues to step 271, and waits for emptying the stacking plate from these securities.

如果在294步该设备没有被确定为按分选方式操作,或者如果在296步没有检测到该批量的完成,则控制过程转至295步,在295步检验叠放计数以确定叠放板是否填满到它的容量。 If the device is not in step 294 is determined to be operating by sorting mode, or if not detected completion of the batch in step 296, the control procedure advances to step 295, step 295 tests to determine counting stacked stacking plate whether filled full to its capacity. 若在295步确定叠放板没有填满,则控制过程返回到298步,为下一个证券累加数据作好准备。 If the determination in step 295 the stacking plate is not full, then control returns to step 298 to prepare for the next accumulation of data security. 若叠放板已填满,则控制过程转至297步,给出叠放已填满的适当显示。 If the stacking plate is full, the control procedure advances to step 297, given the appropriate stacking the filled display. 控制过程从297步转至271步,并等待从叠放盒排空证券。 The control procedure advances to step 271 from step 297, and waits for securities evacuated from the cassette stack.

一旦完成了一个批量时就到达271步,叠放盒是满的,或者已检测到除可疑伪券之外的一个误差。 Once the batch proceeds to a step 271, the stacking cassette is full, or an error has been detected in addition to the suspected bogus. 在271步期间,将设备的状态通知给用户(或控制主机)。 During step 271, the status of the device to notify the user (or control panel). 为了清除该误差或者按其它方式恢复计数,必须从叠放盒除去证券。 In order to clear the error or otherwise restored by counting, securities must be removed from the cassette stack. 和检测可疑伪券相比,检测其它误差也将在计数中引起不确定性。 And detecting suspect counterfeit note compared to the detection of other errors also causes uncertainty in the count. 例如,如果由于存在双重误差达到271步,操作员不能确定从斗仓中应除去两张或是应除去三张证券才能恢复正常操作。 For example, if the presence of a double error of step 271, the operator can not determine should be removed from the hopper in two or three securities should be removed in order to restore normal operation. 双重误差可能由同时通过两张证券引起,或者由通过一张遮光性异常的证券引起。 Double error may be caused by the same time by two securities, or through a blackout caused by abnormal securities. 为了避免破坏累加计数和总数的完整性,所以除伪假误差之外的误差的检测将使运行计数复位并且从叠放盒板要除去所有的证券(在271步),并且使它们或者返回到斗仓,或者终止计数。 To avoid damage to the integrity of the accumulated counts and totals, so in addition to the error detecting fraudulent error and will reset the run count to be removed from the stack all securities holder plate (at step 271), and to make them return, or hopper or terminate counting. 类似地,其它两个可导向到271步的条件(完成一个批量,或完成了一个整叠放盒)也要求从叠放盒板除去所有的证券。 Similarly, the other two conditions directed to step 271 (a batch is completed, or the completion of a full stacking box) also requires the removal of all securities from the cassette stacking plate. 当叠放盒光传感器表示:证券已从叠放盒板除去时,操作恢复,并且控制过程转到273步。 When the stacked cell light sensor indicates: Stacked Securities removed from the cassette plate, operation resumes and the control procedure goes to step 273.

273步是一个保证证券计数不在“隐证券”条件的过程。 273 is a step to ensure the security conditions are not counting "implicit securities" process. 隐证券是斗仓中最后一张证券,它是在271步之前电机停止操作期间从斗仓加到叠放盒中的,而不是传送到叠放盒中的。 Implicit securities is the last one hopper securities, which is before the motor is stopped at step 271 from the hopper stack added during operation of the cartridge, instead of passing into the stacking box. 由于操作员看不见这样一张证券,并且在斗仓中没有余下其它证券,所以在273步要进行检验,以确定斗仓是否像由斗仓光传感器确定的那样是空的。 Since the operator can not see such a stock, and no other securities remaining in the hopper, it should be tested at step 273 to determine if the image is determined by the hopper photosensor hopper is empty as. 若斗仓是空的,重新启动电机,并使电机运行一个空的暂停时间,把隐证券提供给叠放盒板。 If the hopper is empty, restart the motor, and a motor running empty pause time, the hidden security provided to the cassette stacking plate. 然后,在275步,由于从叠放盒板已移走了所有的证券,所以叠放盒板计数复位,控制过程返回到226步。 Then, in step 275, since the board has been removed from the cassette stack all the securities, the stacking cassette plate count is reset, control returns to step 226.

可以对检测可疑伪券的前述的控制过程部分进行修改,以便实现检测可疑伪券的另一种方法,在结合信号调节电路110a讨论时曾提到过这个替代方法。 The control process may be suspected counterfeit notes section detects the modification, in order to achieve a further method for detecting the suspected counterfeit notes, in conjunction with reference to the signal conditioning circuit 110a through this alternative method had discussed. 在实施该替代方法的控制过程的修改的方案中,CPU累加:(i)超过第一预定基准值的磁检测调节信号的相继取样值的一个第一计数;以及(ii)超过第二预定基准值的取样值的第二计数。 In an alternative embodiment of the control procedure of the method of the modified embodiment, CPU accumulation: (i) successive sample values ​​of the magnetic detection signal exceeds a first adjustment value of a predetermined first reference count; and (ii) exceeds a second predetermined reference second count value sample values. 将每个第一、第二累加计数与一个或多个和真券相关的基准值进行比较,以便检验每一个证券。 Each of the first and second counts up with one or more genuine note and the associated reference value, in order to test each of the securities. 具体来说,该替代过程利用了累加计数的计数寄存器和指示证券是否已通过或没能通过检验比较的标志寄存器。 Specifically, whether this alternative process utilizes accumulated counts count register indicating the securities have failed the test by comparing flag or register. 在检测间隔前、在控制过程的228步和230步,使这些寄存器初始清零。 Prior to detection interval, in step 228 and step 230 of the process control, these initial register is cleared.

在该替代证券检验方法中,图7B控制过程的260步由图7E中所示的一个过程代替,并记为260a。 In this alternative document verification method, step 260 of FIG. 7B is replaced by the control process shown in a process 7E, the referred to and 260a.

现在参照图7E,在400步控制器操作A/D转换器,从调节电路110a获得调节信号的取样值。 Referring now to 7E, the operation of A / D converter at step 400 controller, 110a adjustment signal sample values ​​obtained from the regulator circuit. 然后,在402步,控制器比较在400步得到的取样值和代表最小阈值的一个预定基准值VL。 Then, in step 402, the controller compares the sample value obtained in step 400 and a predetermined threshold value represents the minimum reference value VL. 若取样值不超过VL,则控制程序分支到418步,用于对大于VL的相继取样值计数的计数寄存器复位。 If the sample does not exceed VL, the control program branches to step 418, a successive sample values ​​of the count is greater than VL Count registers. 控制器然后前进到414步,对此,后面再予以说明。 The controller then proceeds to step 414, which, then later be described.

若在402步确定取样值大于VL,则控制器前进到404步。 If it is determined in step 402 is greater than the sample value VL, the controller proceeds to step 404. 在404步,用于对大于VL的相继取样的计数进行保持的计数寄存器加1。 In step 404, for counting successive sampled count is greater than the VL register 1 is added to maintain. 下面称这种寄存器为“低计数”寄存器。 This register is hereinafter referred to as "low-count" register. 然后,控制器前进至406步。 The controller then proceeds to step 406.

在406步,比较含在低计数寄存器中的值与一个预定的基准值,该基准值对应于超过VL的相应取样的最小数,而VL是确认一个证券为真券所需要的值。 In step 406, the comparison count register containing the low value with a predetermined reference value, the reference value corresponds to the minimum number of samples corresponding to more than VL, VL is confirmed and security is a genuine banknote desired value. 若低计数寄存器的累加值超过预定的基准值,则控制过程前进到408步,在408步使标志寄存器置位,从而表明:已经超过了必要的最小计数值、并且相对于低计数寄存器的值而言该证券已经通过了核实检验。 If the low-count register the accumulated value exceeds a predetermined reference value, the control process proceeds to step 408, at step 408 that the flag register is set, indicating that: has exceeded the minimum count necessary, with respect to the low count register value For the securities it has passed the verification test. 控制器而后前进到410步。 The controller then proceeds to step 410.

若在406步低计数寄存器的值不超过必要的最小值,则控制器前进至410步。 If no more than the necessary minimum value in the low count register step 406, the controller proceeds to step 410.

在410步,将在400步得到的取样值与一个预定的限值VH进行比较。 In step 410, comparing the sampled value obtained in step 400 with a predetermined upper limit value VH. 若发现取样值大于VH,则控制器前进到412步,使另一个寄存器(“高计数”寄存器)加1。 If the sample value is greater than the VH was found, then the controller proceeds to step 412, so that the other register (the "high count" register) is incremented. 该控制器然后到414步。 The controller is then to step 414.

若在410步发现取样值不大于VH,则控制器进到414步。 If it is found at step 410 is not greater than the sample value VH, the controller proceeds to step 414.

在414步,将在高计数寄存器中累加的值与一个预定的基准值或最大值进行比较,高于该基准值的证券被确认为可疑的伪券。 In step 414, the count will be accumulated in a high register with a predetermined reference value or maximum value are compared, higher than the reference value is identified as suspicious securities counterfeit note. 如果确定:高计数寄存器的内容大于该预定的最大值,则控制器进到416步,使通过标志寄存器置位,这表示一个可疑的伪券。 If it is determined: the content of the high count register is greater than a predetermined maximum, the controller proceeds to step 416, passing through the register flag is set, this indicates a suspected counterfeit notes. 控制器然后前进到262步(见图7B所示的控制过程)。 The controller then proceeds to step 262 (see FIG control process shown 7B). 若在414步在高计数寄存器中累加的值不超过该预定的最大值,则控制器从414步进到图7B的262步,并且如先前所述使程序继续执行。 If the maximum does not exceed the predetermined value in the accumulated count register 414 in the high step, the controller 414 from the step 262 to the step of FIG. 7B, and as previously described so that the program continues.

由图7E所示的过程可以看出,通过标志寄存器表示对一个真正的证券的一次成功的检验。 The process shown in FIG. 7E can be seen, represented by a flag register for a real test of a successful security. 若通过标志寄存器不置位,这样的条件表示该证券是一个可疑的伪券。 If the register is not set by a flag, such a condition indicates that the security is a suspected counterfeit notes. 如果在证券检测期间为数不多的相继取样值大于下阈值VL、或者预定数目的取样值大于上限值VH,则表示这个证券是伪券。 If, during successive sampling few securities detected value is greater than the lower threshold VL, or a predetermined number of samples is greater than the upper limit value VH, it indicates that a counterfeit note securities. 值得注意的是,这两个标准可像这里所述的按组合的方式实现,但如果期望,也可单个地使用这两个检验标准中的任何一个。 Notably, the two standards may be as described herein in combination implemented by, but if desired, may be used any single one of the two test standards.

在该替代证券检验方法的实践中值得注意的是,可对结合图7D所述的伪券检测步骤288进行修改,使其主要的功能就是确定通过标志是否代表一个可疑伪券的检测结果。 Notably in the practice of the alternative document verification method is, modifications may be made in connection with Fig. 7D counterfeit notes detected in step 288, it is determined by the main function is questionable whether the flag representative of a result of the detection of counterfeit notes.
