本发明涉及物品跟踪领域，更具体的，涉及行李到港自动跟踪系统和方法。The invention relates to the field of article tracking, and more specifically, to a luggage arrival automatic tracking system and method.
背景技术Background technique
目前，国际机场海关对可疑行李的跟踪处理缺乏科技高效的方法。例如，在贴标签之前不对物品进行跟踪，这样无法掌握未跟踪期间物品的状况。同时，使用单一的设备(例如光眼)对物品进行跟踪无法保证跟踪结果的准确性。从X射线检验系统至标签打印系统之间的传送带区域，可疑行李的自动跟踪定位识别系统在整个机场集成行李管理中起着至关重要的作用，该系统使得标签打印系统能够正确的将标签打印与粘贴至行李上，来保证可疑行李的所属乘客能够及时被控制。然而如果不能保证对行李正确的自动跟踪、以及对可疑行李识别和定位的准确性，服务质量就难以得到保障。At present, the customs at international airports lack scientific and efficient methods for tracking and processing suspicious luggage. For example, items are not tracked until they are tagged, so there is no way to know the condition of the item during the untracked period. At the same time, using a single device (such as a light eye) to track items cannot guarantee the accuracy of the tracking results. From the X-ray inspection system to the conveyor belt area between the label printing system, the automatic tracking, positioning and identification system for suspicious baggage plays a vital role in the integrated baggage management of the entire airport. This system enables the label printing system to correctly print the label And paste it on the luggage to ensure that the passengers who belong to the suspicious luggage can be controlled in time. However, if the correct automatic tracking of luggage and the accuracy of identifying and locating suspicious luggage cannot be guaranteed, the quality of service will be difficult to guarantee.

Examples of devices or articles described herein are capable of being manufactured, used, or transported in a variety of positions or orientations.
为了保证物品的准确传输并且正确定位特定物品，当前的传输系统在物品入口和传输终点之间设置有监视系统。然而，仅仅利用单一设备(例如光眼)得到的追踪结果可能是不准确的，也无法得到进一步校验。特别的，对于物品(包括但不限于行李、集装箱等)查验领域，除了设置有射线(如X射线)检查系统和物品标签(如射频识别(RFID)标签)打印系统，还可以在不影响现有物品传送和检查的情况下，在物品的传输路径中设置用于物品跟踪的系统来进行辅助如标签打印和粘贴等后续操作，进一步提高操作效率并降低人力成本。优选地，本发明的实施例的技术方案可以应用在物品经过安全检查之后以及对经过安全检查的物品施加标签之前，从而能够在物品的流转传输全程中保持对物品的跟踪，并能够及时对异常情况做出响应。In order to ensure the accurate transmission of items and the correct positioning of specific items, the current transport system is provided with a monitoring system between the entry of the items and the end of the transport. However, tracking results obtained using only a single device (such as a light eye) may be inaccurate and cannot be further verified. In particular, for the inspection field of articles (including but not limited to luggage, containers, etc.), in addition to setting up a radiation (such as X-ray) inspection system and a printing system for article labels (such as radio frequency identification (RFID) labels), it can also In the case of item transmission and inspection, a system for item tracking is set up in the item transmission path to assist in follow-up operations such as label printing and pasting, further improving operational efficiency and reducing labor costs. Preferably, the technical solutions of the embodiments of the present invention can be applied after the items have passed the security check and before applying tags to the items that have passed the security check, so that the tracking of the items can be kept during the entire circulation and transmission of the items, and abnormalities can be detected in a timely manner. respond to the situation.
图1是图示了根据本发明的实施例的用于物品跟踪的系统100的简化框图。系统100可以包括用于物品跟踪的装置110以及可选的连接到装置110的控制器120。装置110可以包括x个第一探测设备111a-111x(x为大于1的整数)；y个第二探测设备112a-112y(y为大于等于1的整数)；以及可选的z个监控设备113a-113z(z为大于等于1的整数)。FIG. 1 is a simplified block diagram illustrating a system 100 for item tracking according to an embodiment of the present invention. System 100 may include a device 110 for item tracking and optionally a controller 120 connected to device 110 . The apparatus 110 may include x first detection devices 111a-111x (x is an integer greater than 1); y second detection devices 112a-112y (y is an integer greater than or equal to 1); and optionally z monitoring devices 113a -113z (z is an integer greater than or equal to 1).
第一探测设备111a-111x被沿一个或多个物品移动的路径排布，并且用于探测物品的位置。本领域技术人员可以根据实际需要(例如需要进行跟踪的区域大小、物品路径的长度和形状等)来设计第一探测设备111a-111x的设置位置。第一探测设备111a-111x可以是现在已知或将来开发出的任何具有探测物品位置功能的设备。优选地，第一探测设备111a-111x可以是光学探测设备，例如光眼探测设备。本文中以光眼探测设备为示例对实施例进行了描述，但应理解诸如超声波探测系统、摄像头探测系统等之类的其它系统也是可能的。根据本发明的实施例，光眼探测设备可以采用反射型或对射型光眼。在操作中，例如当物品经过光眼时，物品遮挡光眼的光路，从而光眼探测到物品正在经过其所布置的位置。The first detection devices 111a-111x are arranged along the path of movement of one or more items and are used to detect the position of the items. Those skilled in the art can design the setting positions of the first detection devices 111a-111x according to actual needs (such as the size of the area to be tracked, the length and shape of the path of the item, etc.). The first detecting devices 111a-111x may be any devices that have the function of detecting the position of objects known now or developed in the future. Preferably, the first detection devices 111a-111x may be optical detection devices, such as optical eye detection devices. Embodiments are described herein taking a photo-eye detection device as an example, but it should be understood that other systems such as ultrasonic detection systems, camera detection systems, etc. are also possible. According to the embodiment of the present invention, the photoeye detection device may adopt a reflective or through-beam photoeye. In operation, for example, when an object passes by the photocell, the object blocks the light path of the photocell, so that the photocell detects that the object is passing the position where it is arranged.
第二探测设备112a-112y被沿一个或多个物品移动的路径排布，并且用于探测物品的第一特征。本领域技术人员可以根据实际需要(例如需要进行跟踪的区域大小、物品路径的长度和形状等)来设计第二探测设备112a-112y的设置位置。优选地，第二探测设备112a-112y可以被沿物品移动的路径等距离地排布。第二探测设备112a-112y可以是现在已知或将来开发出的任何具有检测物品的特征的设备。优选地，第二探测设备112a-112y可以是光学探测设备，例如光栅探测设备。本文中以光栅探测设备为示例对实施例进行了描述，但应理解诸如RFID探测系统、压敏感测系统等之类的其它系统也是可能的。光栅可以例如是光眼的阵列(一维或二维阵列)。在利用光眼来跟踪物品的同时，光栅可以识别物品的特征，从而能够提高物品跟踪的容错能力。The second detection devices 112a-112y are arranged along the path of travel of the one or more items and are used to detect the first characteristic of the items. Those skilled in the art can design the setting positions of the second detection devices 112a-112y according to actual needs (such as the size of the area to be tracked, the length and shape of the object path, etc.). Preferably, the second detection devices 112a-112y may be arranged equidistantly along the path of movement of the item. The second detection devices 112a-112y may be any devices that are known or developed in the future and have the feature of detecting objects. Preferably, the second detection devices 112a-112y may be optical detection devices, such as grating detection devices. Embodiments are described herein using the example of a grating detection device, but it should be understood that other systems such as RFID detection systems, pressure sensitive sensing systems, etc. are also possible. The grating may eg be an array of photocells (one or two dimensional array). While using the optical eye to track the item, the grating can identify the characteristics of the item, which can improve the fault tolerance of item tracking.
根据本发明的实施例，监控设备113a-113z可以是诸如摄像头之类的图像记录设备。同样可以根据实际需要来设计一个或多个监控设备113a-113z的设置位置。According to an embodiment of the present invention, the monitoring devices 113a-113z may be image recording devices such as cameras. Likewise, the setting positions of one or more monitoring devices 113a-113z can be designed according to actual needs.
系统100可以包括通信地连接(例如有线连接或无线连接)到装置110的控制器120。控制器120可以用于接收第一探测设备111a-111x探测到的物品位置信息和第二探测设备112a-112y探测到的物品第一特征信息。System 100 may include a controller 120 communicatively coupled (eg, wired or wirelessly) to device 110 . The controller 120 may be configured to receive item position information detected by the first detection devices 111a-111x and first feature information of the items detected by the second detection devices 112a-112y.
第一探测设备111a-111x被配置为对一个或多个物品进行跟踪，以确定物品的当前位置。例如，设置在物品传送路径旁的光眼探测设备可以根据检测到的光波被阻挡的时间来对当前通过该光眼探测设备的物品进行跟踪。光眼探测设备可以包括能够实现对物品位置的检测的任何光学、电子、光电实现方式。第一探测设备111a-111x对物品的跟踪还包括：记录特定物品通过特定位置的时刻、以及一段时间内通过特定位置的物品计数。优选地，第一探测设备111a-111x可以沿物品传输的路径以固定间隔布置，例如等距离地布置。The first detection devices 111a-111x are configured to track one or more items to determine the current location of the items. For example, the optical eye detection device arranged beside the item conveying path can track the item currently passing through the optical eye detection device according to the time when the detected light wave is blocked. The optical eye detection device may include any optical, electronic, or optoelectronic implementation capable of detecting the position of an item. The tracking of the items by the first detection devices 111a-111x also includes: recording the moment when a specific item passes through a specific location, and counting the number of items passing through a specific location within a period of time. Preferably, the first detection devices 111a-111x may be arranged at fixed intervals along the path of conveying the articles, for example equidistantly.
第二探测设备112a-112y可以被配置为记录物品的第一特征。第一特征可以是一切特定于物品、使得物品能够被区分开来的特性；包括但不限于下述项中的一个或多个的任意组合：特定于物品的标签、物品的形状、物品的颜色、以及物品的尺寸(例如，长度、宽度、高度等)。特定于物品的标签可以是由标签系统提供至物品的RFID标签、荧光标签、气味标签、磁扣、二维码、条形码等。The second detection device 112a-112y may be configured to record the first characteristic of the item. The first characteristic may be any characteristic specific to the item that enables the item to be distinguished; including but not limited to any combination of one or more of the following items: item-specific label, item shape, item color , and the dimensions of the item (eg, length, width, height, etc.). Item-specific tags may be RFID tags, fluorescent tags, scent tags, magnetic buttons, QR codes, barcodes, etc. provided to the item by the tagging system.
根据本发明的一个实施例，光栅可以是由多个光眼组成的阵列(一维或二维阵列)。在这种情况下，当被检测物品经过时，根据检测模式的不同(对射型或反射型)，被检测物品通过吸收光线或通过将光线反射到光电传感器的收光器，从而导致收光器接收的光线强度产生变化，其变化值触发开关信号输出，实现检测物品的第一特征(例如，长度、高度、宽度等)的功能。优选地，第二探测设备112a-112y可以沿物品传输的路径以固定间隔布置，例如等距离地布置。According to an embodiment of the present invention, the grating may be an array (one-dimensional or two-dimensional array) composed of multiple optical eyes. In this case, when the detected item passes by, depending on the detection mode (through-beam or reflective), the detected item either absorbs light or reflects light to the light receiver of the photoelectric sensor, resulting in light receiving The intensity of the light received by the detector changes, and the change value triggers the output of the switch signal to realize the function of detecting the first feature (such as length, height, width, etc.) of the item. Preferably, the second detection devices 112a-112y may be arranged at fixed intervals along the path of conveying the articles, for example equidistantly.
物品跟踪的系统100还可以被配置为将第二探测设备112a-112y所记录的第一特征与物品的第一预定义特征进行匹配。根据本发明的一个实施例，控制器120还可以用于从外界接收或预先存储物品的第一预定义特征。此外，控制器120可以用于将第二探测设备112a-112y探测的物品第一特征与第一预定义特征进行比较匹配。当物品经过第一探测设备111a-111x中的一个第一探测设备时，如果控制器120判定从第二探测设备112a-112y中选出的一个第二探测设备检测到的物品第一特征与物品的第一预定义特征匹配，则控制器120就记录该第一探测设备探测的该物品的位置，以实现对物品的跟踪。The system 100 for item tracking may also be configured to match the first characteristic recorded by the second detection device 112a-112y with the first predefined characteristic of the item. According to an embodiment of the present invention, the controller 120 may also be used to receive or pre-store the first predefined feature of the item from the outside. In addition, the controller 120 can be used to compare and match the first feature of the item detected by the second detection device 112a-112y with the first predefined feature. When the item passes through one of the first detection devices 111a-111x, if the controller 120 determines that the first feature of the item detected by a second detection device selected from the second detection devices 112a-112y is consistent with the first feature of the item If the first predefined feature matches, the controller 120 will record the position of the item detected by the first detection device, so as to realize the tracking of the item.
监控设备113a-113z沿物品移动的路径排布，并且用于探测物品的第二特征，从而获得关于物品位置和/或特征的附加有效数据。这可以显著提升对物品位置确定的准确性。例如，监控设备113a-113z可以拍摄物品的图像，并且系统100能够识别拍摄的图像中是否存在与预定义的特征匹配的特征。Monitoring devices 113a-113z are arranged along the path of movement of the item and are used to detect a second characteristic of the item to obtain additional useful data regarding the position and/or characteristics of the item. This can significantly improve the accuracy of item location determination. For example, monitoring devices 113a-113z may take images of items, and system 100 can identify whether there are features in the captured images that match predefined features.
根据本发明的一个实施例，控制器120可以用于接收监控设备113a-113z探测到的物品第二特征信息，并且还可以用于从外界接收或预先存储物品的第二预定义特征。此外，控制器120可以用于将监控设备113a-113z探测的物品第二特征与第二预定义特征进行比较匹配。例如，可以使用各种图像识别算法(例如局部识别算法等)来进行图像识别和特征匹配操作。例如，可以将物品的局部显著特征作为用于识别和匹配的第二特征。当物品经过第一探测设备111a-111x中的一个第一探测设备，如果控制器120判定从监控设备113a-113z中选出的一个监控设备拍摄的图像中识别出的物品第二特征与物品的第二预定义特征匹配，则控制器120就记录该第一探测设备探测的该物品的位置，以实现对物品的跟踪。优选地，监控设备113a-113z可以沿物品传输的路径以固定间隔布置，例如等距离地布置。According to an embodiment of the present invention, the controller 120 can be used to receive the second feature information of the item detected by the monitoring devices 113a-113z, and can also be used to receive or pre-store the second predefined feature of the item from the outside. In addition, the controller 120 may be configured to compare and match the second feature of the item detected by the monitoring devices 113a-113z with the second predefined feature. For example, various image recognition algorithms (such as local recognition algorithms, etc.) can be used to perform image recognition and feature matching operations. For example, local salient features of items may be used as the second features for identification and matching. When the item passes through one of the first detection devices 111a-111x, if the controller 120 determines that the second feature of the item identified in the image taken by a monitoring device selected from the monitoring devices 113a-113z is consistent with the item's If the second predefined feature matches, the controller 120 will record the position of the item detected by the first detection device, so as to track the item. Preferably, the monitoring devices 113a-113z may be arranged at regular intervals, for example equidistantly, along the path of item transport.
在优选的实施例中，在物品移动路径上布置有匀速运动的传送带以将一个或多个目标物品移动到目的地。在此情形中，该目标物品随传送带行进的速度一定且光眼的位置一定，则在正常情况下某一个物品移动经过预定位置的两个光眼的时间差应当保持恒定。例如，在包括共L个光眼的情况下，将一个目标物品触发第N个光眼的时间(即，经过第N个光眼探测到该物品的时间)标记为TN，将该目标物品触发第M个光眼的时间为TM，则时间差ΔT＝TM-TN应为恒定值(其中，L、M、N为整数且L＞M＞N)。从而，本领域技术人员能够以计算和监视时间差ΔT的方式对目标物品进行跟踪。依据光眼设置的数量和位置不同，可以利用不同的光眼组合来跟踪不同的物品。例如，对于两个或更多个不同的物品，可以分别通过计算ΔT1＝TM-TN，ΔT2＝TR-TS……等等(R、S为整数且R＞S)，得出不同的ΔT值，以跟踪不同的物品，从而实现对物品的精确追踪。In a preferred embodiment, a conveyor belt moving at a constant speed is arranged on the item moving path to move one or more target items to a destination. In this case, if the speed of the target item traveling along the conveyor belt is constant and the position of the photocell is constant, then under normal circumstances the time difference between the two photocells where an item moves past the predetermined position should remain constant. For example, in the case of a total of L optical eyes, the time when a target item triggers the Nth optical eye (that is, the time when the Nth optical eye detects the item) is marked as TN , and the target item The time to trigger theMth photoeye is TM, and the time difference ΔT=TM -TN should be a constant value (wherein, L, M, and N are integers and L>M>N). Thus, those skilled in the art can track the target item by calculating and monitoring the time difference ΔT. Depending on the number and position of photocells, different combinations of photocells can be used to track different items. For example, for two or more different items, it can be calculated by calculating ΔT1 =TM -TN , ΔT2 =TR -TS ...... etc. (R,S are integers and R>S), Different ΔT values are obtained to track different items, so as to achieve accurate tracking of items.
在优选的实施例中，根据本发明的实施例的物品跟踪的装置还可以包括计数器，用于判定多个物品在经过一组光眼的过程中是否出现物品数量增减。例如，在包括共L个光眼的情况下，每当物品经过第N个光眼时计数器执行计数值加1操作，每当包裹经过第M个光眼时计数器执行计数值减1操作。从而，可以基于计数值来确定在第N个光眼和第M个光眼之间的路径中物品的情况，例如是否存在物品数量增加或减少的情况。基于上述原理，可以利用多个光眼的不同组合来分别进行计数，以确定在不同的路径段中物品的情况。In a preferred embodiment, the device for tracking items according to the embodiment of the present invention may further include a counter, which is used to determine whether there is an increase or decrease in the number of items when the items pass through a set of optical eyes. For example, in the case of including a total of L photocells, the counter performs an operation of adding 1 to the count value every time an item passes through the Nth photocell, and the counter performs an operation of decrementing the count value by 1 every time a package passes through the Mth photocell. Therefore, the status of items in the path between the Nth optical eye and the Mth optical eye can be determined based on the count value, for example, whether there is an increase or decrease in the number of items. Based on the above principles, different combinations of multiple optical eyes can be used to perform counting respectively, so as to determine the conditions of items in different path segments.

可选地，根据本发明的物品跟踪的方法还可以包括：步骤205，探测一个或多个物品的第二特征；和步骤206，判断探测的物品第二特征与第二预定义特征是否匹配。如果物品第二特征与第二预定义特征匹配，则记录目前探测的物品位置，以实现对物品的跟踪。Optionally, the method for item tracking according to the present invention may further include: step 205, detecting the second feature of one or more items; and step 206, judging whether the detected second feature of the item matches the second predefined feature. If the second feature of the item matches the second predefined feature, the currently detected position of the item is recorded, so as to track the item.
