Description

一种自助验货方法和系统 技术领域
本发明涉及超市智能自助验货的方法和系统及其应用的技术领域，更具体地，涉及一种自助验货方法和系统。
背景技术
超市交易必需买卖公平。超市不论采用何种收银方法和系统，必需贯彻买卖公平的原则。在超市的公平交易中，对商品进行验货是一道必不可少的手续。为此，超市必需把好商品的验货关：消费者购买商品，超市为每件商品验货，确保消费者为其选购商品支付该付的货款，超市收到该收的货款后，将消费者选购商品和收银条交给消费者，消费者带着购买的商品离开超市。至此，超市完成了一次公平的交易。
传统的收银方法是人工收银方法，其中，商品验货也是用人工方法完成的，与该方法联用的系统是收银台。收银台设立在超市在商场出口处，一名收银员负责办理收银手续。消费者提着购物筐或推着购物车，来到收银台前，将购物筐或购物车内选购的商品布列在商品输送台上。收银员利用收银台上的扫描器对商品逐个进行扫描，读取商品包装上的条形码，获得商品的信息，如商品名称、单价等，存储在收银台上的计算机内。收银员每扫完一件商品，就把该商品递给消费者，一并完成了对商品的验货和发货的手续。所述的计算机制作收银条(电子版)，显示在收银台上的屏幕上。消费者按显示的金额数(该付的货款)，把货款付给收银员。付款方式可是现金或刷卡。收银员完成收款后，启动收银台上的打印机，打印收银条(纸质凭条)。收银员把收银条交给消费者。消费者带着选购的商品离开超市。至此，超市完成了一次公平的交易。传统的收银方法有以下缺点。a)一个超市往往需设多个收银台，每个收银台需配设一名收银员，一天需2-3班，造成超市员工编制庞大，增加了超市的营运成本。b)节假日消费者集中时，经常会出现消费者排长队等待收银的情况，浪费了消费者大量的宝贵时间。c)收银员工作疏忽或与外人勾结作弊，使商品漏检或被盗，导致超市商品丢失，提高了超市的营运成本。d)收银员在尚未收款的情况下就把完成扫描的商品一件件 地发放给消费者，这种做法存有不必要的、难以预期的风险。
目前，国内外一些大型超市采用一种自助收银方法，其中的商品验货手续也是由消费者自助完成，与该方法联用的系统是自助收银台。该台通过触摸屏和扬声器，用图像和语音提示消费者，消费者通过按揿触摸屏显示的按钮应答，人机之间的交流互动引领消费者进行并完成自助收银操作。该法所采用的验货方法：消费者提着购物筐或推着购物车，来到该台前，从购物筐或推车取出一件商品，利用该台上的扫描器自助扫描该商品，读取包装上的条形码，获得商品信息，如商品名称、单价、重量区间等，存储在该台上的计算机内。消费者每扫完一件商品，就把该商品放在位于该台一侧的电子称称盘上。如电子称称得商品的重量在条形码记录的重量区间内，说明称盘上的商品就是刚扫描过的那件商品，验货通过，然后该台会指引消费者扫描下一件商品。如电子称称得商品的重量不在条形码记录的重量区间内，说明称盘上的商品不是刚扫描过的那件送验商品。这是因为消费者扫描商品甲，却把商品乙放到称盘上，即发生了中途调换商品的缘故，验货不通过。此时该台会指引消费者取下刚放上称盘的商品(商品乙)，对其进行扫描后，再放回到称盘上。这样，购物筐或购物车内的选购商品被一次一件地转移到电子称称盘上。消费者通过触摸屏将全部商品扫描完毕的信息通知该台，至此，自助验货手续全部完成。接着，进入传统的自助收银流程：触摸屏显示收银条(电子版)、征求消费者的付费方式、消费者选择付费方式：现金或刷卡、微信和支付宝支付、消费者用选择的方式在该台的收银器上完成自助付费的操作、该台的打印机打印出收银条(纸质)消费者取了该收银条和电子称称盘上的商品，离开超市。至此，超市完成了一次公平的交易。上述的自助验货方法有如下缺点。该法无法检验某些不良的消费行为：a)一些不自觉的、贪图小利的消费者往往会多取商品(如取五件商品)，仅自助扫描其中一部分(如仅自助扫描二件商品)，甚至一件也不扫，结果只付部分商品的货款，甚至不付任何货款，却带走了全部商品，给超市造成商品丢失。b)一些不自觉的、贪图小利的消费者会使出中途“掉包”的手段，自助扫描一件廉价的商品(如商品甲)，却将昂贵的、重量与廉价商品差不多的商品(如商品乙)放在称盘上，该法会将两件商品混淆成一件商品，以为商品乙就是商品甲，验货通过，结果消费者仅付购买廉价商品(商品甲)的货款，却带走了昂贵商品(商品乙)，给超市造成商品差价的损失。
发明内容
针对背景技术中的问题，本发明提出一种自助验货方法，包括：
S1，扫描放入货物仓内商品的商品条形码，获得商品条形码信息List，同步地，称取货物仓内商品的商品称取重量C；
S2，根据商品条形码信息List从商品数据库中读取商品数据库中重量K；
S3，判断商品数据库中重量K和商品称取重量C之间的误差是否在设定范围内，如果在，则初验通过，否则，初验失败。
本发明提出一种自助验货系统，包括：
机箱(14)；
货物仓(8)，用于放置待检验的商品，位于机箱(14)内部；
视觉扫描装置，用于扫描放入货物仓内商品的商品条形码，获得商品条形码信息List；
电子称(6)，用于在视觉扫描装置工作时，同步称取货物仓(8)内商品的商品称取重量C；
计算机(1)，计算机(1)放置在机箱(14)内，计算机(1)被配置为：A1，根据视觉扫描装置扫描的商品条形码信息List从商品数据库中读取商品数据库中重量K；A2，判断商品数据库中重量K和商品称取重量C之间的误差是否在设定范围内，如果在，则初验通过，否则，初验失败。
与背景技术相比，本发明有以下优点：
1.大幅降低超市的营运成本
验货和收银由消费者自助完成，超市聘用收银员的人数大幅减少，有助于紧缩超市员工编制，能为超市节省可观的工资开支，能大幅降低超市的营运成本和大幅提高超市营运的效率。同时超市收银员完全可以用机器人所代替，使无人超市得以成功运营成为可能。
2.彻底杜绝了验货过程中商品中途“掉包”的可能性
在背景技术的验货过程中发生商品中途“掉包”的情况是因为两项检测：扫码和称重不在同一时刻进行，商品中途“掉包”需要时间，两项检测之间的时间间隔正好为商品中途“掉包”提供了时间。在本发明方法的验货过程中，同时对送验商品进行读码和称重，彻底杜绝了商品中途“掉包”的可能性，不仅能减少超市商品 的丢失，还有助于提高超市交易的公平性。
3.验货合格的商品暂存在货物仓内，与消费者分离，最大程度降低商品的失窃率
本发明方法在验货合格后的商品存在货物仓内，与消费者分离。消费者离开超市商品区后，方能打开提货仓门提取货物，离开超市。这种做法使超市不用担负不必要的、难以预期的风险。
4、消费者付费可以少排队，甚至不必排队
本发明所涉的系统造价低廉，超市可大量配置该系统，有助于消费者付费时少排队，甚至不排队，提高了超市的营运效率，为消费者节省大量宝贵的时间。

具体实施方式
下面参照附图描述本发明的实施方式，其中相同的部件用相同的附图标记表示。
超市机器人自助验货方法
本发明提出一种超市机器人自助验货方法。如图1所示，本发明的方法包括：
S1，扫描放入货物仓内商品的商品条形码，获得商品条形码信息List，同步 地，称取货物仓内商品的商品称取重量C。所述扫描为视觉扫描，可以采用相机、条形码识别模块等设备。所述商品条形码可以是二维码、一维码等。
在本发明中，“同步地”是指几乎同时，货物仓内的视觉扫描以很高的频率(例如毫秒级别)对商品条形码进行扫描，
S2，如果从数据库中读取的商品条形码信息与S1中读取的商品条形码信息一致，则根据商品条形码信息List从商品数据库中读取商品数据库中重量K。否则验证失败。
S3，判断商品数据库中重量K和商品称取重量C之间的误差是否在设定范围内，如果在，则初验通过，否则，初验失败。
在一种情况下，商品一件一件放入货物仓，则对每一件商品重复S1-S3的步骤。同时，本发明的方法还包括：
S4，在货物仓内实现人货隔离，重复S1-S3的步骤进行复验。
在另一种情况下，多件商品被一次性地放入货物仓。那么，就无法如同一件一件放置商品那样，对每件商品的重量和条形码进行验证。此时，本发明的方法为：
在S1中，扫描货物仓内商品的商品条形码，获得商品条形码信息List，同步地，称取货物仓内商品的重量C，其中C为商品称取总重量C0。
在S2中，根据商品条形码信息List从商品数据库中读取商品数据库中重量K，相加得到商品数据库中总重量K0。
在S3中，判断商品数据库中总重量K0和商品称取总重量C0之间的误差是否在设定范围内，如果在，则初验通过，否则，初验失败。
同时，本发明的方法还包括：
S4，进行人货隔离，重复S1-S3的步骤进行复验。其中，人货隔离可以通过关闭货物仓的门，或者将初验后的商品转移到顾客接触不到的区域来实现。
优选地，在S1中，待验货仓门打开开始计时，一定时间(3秒-30秒)之间内，没有商品放入，则关闭验货仓门。
自助验货系统
本发明还提出一种自助验货系统。
参见图2，本发明的自助验货系统RT包括机箱14，机箱14前面板设置有验 货仓门11，机箱14内设置有验货仓门驱动机构10。验货仓门驱动机构10与验货仓门11组成运动机构，当验货仓门驱动机构10的电机的转轴朝一个方向旋转时，验货仓门驱动机构10驱动验货仓门11开启，当验货仓门驱动机构10的电机的转轴朝另一个方向旋转时，验货仓门驱动机构10驱动验货仓门11关闭。验货仓门11处还可以安装安全光栅15。安全光栅15包括两件配对的组件，分别是光栅发射器和光栅接收器，分别平行安装在验货仓门11的左、右门框上。
在机箱14内部设置有货物仓8，验货仓门11开启后顾客即可将商品放入货物仓8。货物仓8设置在吊篮9上，可选地，可以设置多个吊篮9。机箱14前面板上设置有触摸显示屏2、扬声器3和商品信息输出口13。触摸显示屏2用于与顾客信息互动，扬声器3用于声音提示顾客，商品信息输出口13用于输出收银条等凭证。
在吊篮9的底板上安装有电子称6和称盘7，称盘7压在电子称6的重量传感器上，称盘7以平行和贴近吊篮9底板的方式悬在所述底板的正上方，称盘7的盘面可以正好与机箱14的正面面板上的验货仓门11的下门框平齐。
货物仓8内上方(或侧面)设置有视觉扫描装置，视觉扫描装置包括照明灯4和相机5，相机5的镜头对准货物仓8，照明灯4为称盘7提供照明。视觉扫描装置用于扫描放置在货物仓8内的商品12上的条形码。
验货仓门11关闭后，在货物仓8内进行商品的复验，也就是视觉扫描装置扫描商品12的条形码，并同时称重C。将称取的重量C与条形码对应的数据库中重量K相比对，两者在允许范围内并且判断复验时读取的商品条形码信息与初验时读取的商品条形码信息是否一致，一致才能结账。
如图3所示，本发明的自助验货系统RT还包括支付扫码器19、打印机20和收银条出条口21。打印机20安装在机箱14内。支付扫码器19和收银条出条口21安装在机箱14的正面面板上。支付扫码器19和打印机20通过电缆与计算机1的自助收银模块107连接。支付扫码器19用于在顾客付款时读取银行卡、微信、支付宝二维码等。打印机20用于打印收银条并通过收银条出条口21提供给顾客。
图3显示了本发明的自助验货系统背面的结构示意图。本发明的自助验货系统RT还包括：提货仓门22、提货仓门驱动机构23、收银条扫码器25。通过验 证的商品可通过提货仓门22取出。提货仓门22和收银条扫码器25安装在机箱14的背面面板上，提货仓门驱动机构23、收银条扫码器25通过电缆与计算机1的提货仓门驱动控制模块108(见图3)连接。提货仓门驱动机构23用于打开和关闭提货仓门22。收银条扫码器25用于读取打印机20打印的，从收银条出条口21输出的收银条上的二维码，二维码信息正确才打开提货仓门22。
如图3所示，自助验货系统RT还包括：提货仓门安全光栅24。提货仓门安全光栅24包括两件配对的组件，分别是光栅发射器和光栅接收器，分别平行安装在提货仓门22的左、右门框上。提货仓门驱动机构23连接至计算机1的提货仓门驱动控制模块108(见图3)。
图4显示了本发明的自助购物系统的电路原理图。计算机1设置在机箱14内部。计算机1包括图文语音视频提示模块101、商品信息数据模块102、验货仓门驱动控制模块103、条形码识别模块104、称重模块105、自助收银模块107和提货仓门驱动控制模块108。图文语音视频提示模块101、商品信息数据模块102、验货仓门驱动控制模块103和商品信息输出口13分别通过电缆与计算机1连接。触摸显示屏2和扬声器3分别通过电缆与图文语音视频提示模块101连接。验货仓门驱动机构10通过电缆与驱动控制模块103连接。照明灯4和相机5通过电缆与条形码识别模块104连接。电子称6通过电缆与称重模块105连接。支付扫码器19和打印机20通过电缆与自助收银模块107连接。提货仓门驱动机构23、提货仓门安全光栅24、收银条扫码器25通过电缆与提货仓门驱动控制模块108连接。
下面通过使用过程来再次描述本发明的自助验货系统RT。
当有顾客挑选完商品要结账时，通过触摸显示屏2开启自助验货系统RT，计算机1的图文语音视频提示模块101输出提示信息至触摸显示屏2。计算机1的验货仓门驱动控制模块103驱动验货仓门11打开，顾客将商品12放入货物仓8内。初验通过后，验货仓门驱动控制模块103驱动验货仓门11关闭。
验货仓门11关闭后，电子称6对货物仓8内的商品进行称重，将商品称取重量C传输到计算机1的称重模块105。视觉扫描装置高频地进行扫描，因此在很短时间内，视觉扫描装置扫描商品包装上的条形码，将商品信息List传输到计算机1的条形码识别模块104。商品信息数据模块102根据商品条形码从数据库 中读取商品数据库中重量K。计算机1比较商品称取重量C和商品数据库中重量K的重量差是否在一定范围内，如果在允许范围内，并且判断复验时读取的商品条形码信息与初验时读取的商品条形码信息是否一致，一致，则复验通过。
优选地，在上述初验时验货仓门11不关闭，还可以往货物仓8内添加商品。待客户确认不再添加商品后。验货仓门11关闭，再进行复验：视觉扫描装置扫描商品包装上的条形码，将商品信息List传输到计算机1的条形码识别模块104。商品信息数据模块102根据商品条形码从数据库中读取商品数据库中重量K。计算机1比较商品称取重量C和商品数据库中重量K的重量差是否在一定范围内，如果在允许范围内，并且判断复验时读取的商品条形码信息与初验时读取的商品条形码信息是否一致，一致，则复验通过。如果复验通过，自助收银模块107开始收取费用。顾客通过支付扫码器19支付金额，打印机20打印收银条并从收银条出条口21提供给顾客，收银条上还可以记录吊篮9的编号。支付完后，吊篮9运转到货物仓8内的更靠近机箱14背面区域，顾客拿着收银条到机箱14后面，收银条扫码器25扫描该收银条，如果正确，则打开提货仓门22。通过提货仓门22可以取走商品。
以上示意性的对本发明及其实施方式进行了描述，该描述没有限制性，附图中所示的只是本发明的几种实施方式，实际的结构也并不局限于此。如果本领域的技术人员受其启示，在不脱离本发明创造宗旨的情况下，采用其它形式的结构、传动以及安装及连接方式不经创造性的设计与该技术方案相似的结构方式及实施例，均应属于本发明的保护范围。
