相关申请的交叉引用
本公开基于申请号分别为201810130405.5和201820228875.0，对应的申请日均为2018年02月08日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本公开作为参考。
技术领域
本公开属于智能设备技术领域，尤其涉及一种无人售货设备的售货方法，以及无人售货设备和无人售货系统。
背景技术
目前的无人自动售货机，需要将每个商品上贴上RFID(Radio Frequency Identification，射频识别)电子标签，采用扫描电子标签的方式来识别货品，此方法虽然操作简单方便，但是电子标签成本过高，此方法仍无法普及。
在一些相关技术中，通过在搁架上安装重量传感器，检测顾客取货前后的搁架上货品重量差来进行计价，但是该方法仍然存在一些问题：若顾客选购时，将A层隔板的货品有意或无意地放到B层隔板上的不同价格的货品区域内，则系统计价会出现误差，且系统无法及时判断和发现此问题。更进一步地，若货品继续停留在错误的隔板上，会导致后面的其他顾客购物出现计价误差，整个系统出现价格紊乱，若商品计价低了，导致商家利益损失；若商品计价高了，则会影响用户体验感，甚至引起用户投诉。
在另一些相关技术中，在搁架的上下分别安装红外发射器和红外接收器，通过红外感应判断当前搁架物品的有无，但无法判断物品是否从A位置置换到B位置；同时该方法使用RFID电子标签贴于每一个商品上，用以进一步判断物品是否被更换，而RFID标签成本过高，因此，该方法目前无法广泛普及。

下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参照附图描述根据本公开第一方面实施例的无人售货设备的售货方法。在本公开的实施例中，无人售货设备包括设备本体、门体、安装在设备本体内的至少一层搁架和称重装置摄像装置，其中，搁架上可以放置货品，或者，在搁架上设置托盘，将货品放置在对应托盘上。在实施例中，需要将同品类的货品放置在统一的位置例如预定搁架或者预定托盘。
图1是根据本公开实施例的无人售货设备的售货方法的流程图，如图1所示，本公开实施例的无人售货设备的售货方法包括：
S1，采集售货前后搁架上货品的重量。
在一些实施例中，用户可以通过扫码或其他方式开锁，无人售货设备通过用户信息读取模块获取用户的信息，服务器核对用户信息，并在确认之后发送开锁指令至无人售货设备，无人售货设备的主控模块接收到开锁指令之后控制门锁开启，此时用户可以进行选货，用户选货结束后，主动关闭设备门锁，主控模块检测到关门信号后控制门锁关闭，并进行售货货品的识别和支付控制等流程。
具体地，通过称重装置采集每层搁架上货品的重量，并传输至处理装置，处理装置记录用户取货之前搁架上货品的重量，并在用户取货之后记录售货后搁架上货品的重量。对于搁架上设置托盘的情况，则采集用户取货前后每个托盘上货品的重量。
S2，计算售货前搁架上货品的重量与售货后搁架上货品的重量的变化差值。
在本公开的实施例中，对于直接将货品分类放置于搁架上的情况，获得售货前后每层搁架上货品的重量变化，对于搁架上安装托盘的情况，可以获得售货前后每个托盘上货品的重量变化。
S3，如果变化差值小于第一重量变化阈值，则进行报警提示。
其中，第一重量变化阈值小于或等于零，即售货后搁架上后的重量比售货前搁架上货品的重量大，售货后搁架上货品重量增加。
在本公开的实施例中，如果售货前后搁架上货品的重量的变化差值小于第一重量变化阈值，则判定用户可能将不是某个搁架或托盘的货品放置在了该搁架或托盘，可能是将其他搁架或托盘上的货品放错，或者，也可能用户放入了新的货品，此时，进行报警提示，可以提示用户将货品摆放到正确的位置，同时可以发送报警信息给后台工作人员，以便于调用开门后的全程视频，进一步确认是否发生用户故意破坏、置换商品等不良行为。
根据本公开实施例的无人售货设备的售货方法，不依赖于货品的RFID标签，根据售货前后货品的重量的变化来判断货品是否被错放或被置换，并及时进行报警提示，可以保证后续售货流程的正确执行，保障商家和用户的利益，方法简单易普及。
在本公开的一些实施例中，无人售货设备还可以设置摄像装置，摄像装置可以安装在设备本体内，用于采集搁架上货品的图像。如图2所示，本公开实施例的无人售货设备的售货方法还包括：
S4，采集售货前后搁架上货品的图像。
具体地，通过摄像装置采集设备本体内的图像，记录用户取货前后搁架上货品的图像。
S5，根据图像判断售货前后搁架上货品的变化。
具体地，对图像进行识别，根据售货前后的图像，可以判断售货后，搁架上货品增加或减少或没有变化，以及，在售货后图像变化时还可以识别变化货品的相关信息，例如，颜色、种类、名称、体积、数量。
S6，如果根据图像判断售货前后搁架上货品增加，则进行报警提示。
例如，摄像装置接收到工作指令之后，启动摄像功能，拍摄售货后每层例如1-m层搁架上货品的图像并编号D1、D2、D3…Dm，并调用用户取货前即搁架前一次的图像例如编号分别为C1、C2、C3…Cm，进行图像识别，对比售货前搁架上货品的图像与售货后搁架上货品的图像以判断货品是否变化，如果变化则进一步判断m层搁架上货品是增加还是减少。如果根据图像判断售货前后搁架上货品增加，则判定用户可能将货品放错位置，例如放置了非m层搁架上的货品在m层搁架上，有可能是其他搁架上的货品，也有可能是用户放入了新的获评，此时，进行报警提示，可以提示用户第m层搁架上摆放的货品有误，以便于将其摆放至正确位置，使得后续售货流程正确执行，保证用户利益，同时可以发送报警信息给后台工作人员，以调用开门后的全部视频，以进一步确定是否发生用户故意破坏、置换货品等不良行为，保证商家利益。
在本公开的一些实施例中，如果售货前后搁架上货品的重量的变化差值例如设为δn在限定的认为无变化的范围内，例如满足-Kn≤δn≤Kn,其中，-Kn可以为第一重量变化阈值，Kn可以为第二重量变化阈值，则判定用户未从该搁架上取走货品。或者，根据售货前后搁架上货品的图像判断货品没有变化，则认为用户没有从该搁架上取走货品。
在本公开的实施例，还可以结合称重和图像识别来确定货品的错放或置换，下面在实施例中进行说明。
在本公开的一些实施例中，如果售货前后搁架上货品的重量的变化差值大于第二重量变化阈值，其中，第二重量变化阈值大于或等于零，即货品减少了，认为用户取走了该搁架上的一些货品，可以根据变化差值获得第一售货信息。在本公开的实施例中，规定预先按照类别将货品放置在搁架或托盘上，因而，可以根据货品位置确定售货品类，例如，根据货品放置的搁架或托盘，可以根据预存信息获得对应该搁架或托盘上的货品的相关信息例如品类、单位货品重量、单价等，即基于发生重量变化的货品位置可以确定售货品类；以及，根据重量差和售货品类的预设单位货品重量获得售货数量，重量差与该售货品类的预设单位货品重量的商值即为售出品类货品的数量，为了避免该品类货品单位重量的偏差，商值可以四舍五入取其整数值。
在本公开的实施例中，对于搁架上放置托盘的情况，每层搁架上设置至少一个托盘，托盘具有设定识别码且用于放置预定品类的货品，每个托盘底部设置至少一个称重装置。则第一售货信息可以通过以下获得：称重装置检测当前每个托盘的重量值例如设为B1、B2、B3…Bn，托盘的设定识别码为1-m，并调用售货之前每个托盘的重量值例如设为A1、A2…An，计算售货前第n个托盘上货品的重量与售货后第n个托盘上货品的重量之间的重量差例如δn＝An-Bn，其中，n小于或等于托盘总数量；如果重量差大于对应第n个托盘的第一限值，第一限值大于零，即售货后第n个托盘上货品的重量减少，则判断用户选购了设定识别码为n的托盘中的货品，预存有各个托盘放置货品的相关信息，根据第n个托盘的设定识别码可以获得售货品类；以及，根据售货前后每个托盘上货品的重量的变化差值和对应托盘的售货品类的预设单位货品重量获得售货数量，售货数量即用户选购的该品类货品的数量，满足：Xn＝Zn/δn,Xn为售货数量，Zn为该售货品类的预设单位货品重量，其中，为了避免单位货品重量的偏差，Xn可以四舍五入取其整数值。按照以上将每个托盘的重量信息进行处理以确定用户选购货品。
在本公开的一些实施例中，如果根据图像判断售货前后搁架上货品减少，则根据图像的变化获得第二售货信息。具体地，如果货品减少，则判定用户从第m层搁架上取走货品，并在货品减少时根据图像变化获得减少货品的品类和数量，例如包括但不限于货品的颜色、种类、名称、体积和数量等，也就是用户选择货品的相关信息。
在本公开的实施例中，如果第一售货信息和第二售货信息不一致，则进行报警提示。具体地，如果根据售货前后搁架上货品的重量变化判断的售货品类和数据，与根据图像识别来获得的售货品类和数量不一致，则认为有可能用户将货品放错位置或者置换了货品，此时进行报警提示，可以对用户进行提示，以便于将货品放置至正确的位置，保证后续程 序的正常执行，同时可以发送报警提示信息至后台人员以查看是否发生恶意行为，保证商家利益。
在本公开的实施例中，可以结合称重和图像识别来确定用户的选购信息即售货信息。具体地，如果第一售货信息与第二售货信息一致，则将第一售货信息或第二售货信息确定为最终售货信息。具体地，将通过称重获取的售货信息和通过图像识别获得的售货信息进行比较，例如，比对第m层搁架上第n个托盘上减少的货品数量Xn与图像识别出来减少的货品信息是否一致，如果第一售货信息与第二售货信息一致，则判定用户从m层搁架上取出了第n托盘上的货品，售货数量为Xn，输出用户购买的商品品类、数量和总价格，总价格满足：
Figure PCTCN2019072838-appb-000001
其中，Si为第i个货品的数量，Ki为第i个货品的单价，n为托盘的总个数，并通知服务器，进行金额结算。
在本公开的实施例中，计算货品的数量以及图像识别比对的运算过程，可以是在本地进行数据信息获取后，发送数据至服务器，经云端进行重量计算和图像识别后，再发送售货种类和数据信息至支付系统，进行扣款后，再传送货品品类、数量和价格至本地，进行输出。也可以是由本地进行计算货品的数量以及图像识别比对的运算数据处理，再发送结果至云端支付系统，进行扣款之后，再传送货品品类、数量和价格至本地，进行输出。
基于上述说明，如图3所示，为根据本公开的一个实施例的无人售货设备的售货方法的流程图，包括：
S100，判断是否检测到关门信号，如果是，分别进入步骤S110和S170，否则继续本步骤。
S110，检测当前每个托盘的重量值B1、B2、B3…Bn.
S120，调用每个托盘前一次重量A1、A2、A3…An，判断是否满足δn＝An-Bn>Kn，Kn为每个托盘上货品的标准重量Zn与实测重量之间的允许误差。如果满足，则进入步骤S130，否则进入步骤S140。
S130，调用托盘n上的单个货品重量Zn，计算出售货数量Xn＝Zn/δn.
S140，判断是否满足-Kn≤δn≤Kn，如果满足，则结束，不满足则进入步骤S210。
S150，比对第m层搁架上第n个托盘上减少的货品数量Xn与图像识别出来减少的货品数量是否一致，如果一致，则进入步骤S160，否则进入步骤S210。
S160，输出用户购买的货品品类和数量，每个货品的数量乘以单间，并累加计算总价，进行扣款。
S170，拍摄当前每层搁架上的图像并编号D1、D2、D3…Dn。
S180，调用每层搁架前一次图像C1、C2、C3…Cn，并进行图像比对，判断m层搁架上 是否有货品变化，如果有则进入步骤S190，否则结束。
S190，判断m层搁架上货品是否减少，如果有减少，识别减少货品的颜色、品类、名称、体积和数量等售货信息，并进入步骤S150。否则，进入步骤S200。
S200，启动提示装置，提示用户第m层搁架上摆放的货品有误，请将其摆放至正确位置，同时可以发送报警信息至后台人员，以调用开门后的全程视频，确认用户是否有破坏、置换货品等不良行为。
S210，启动提示装置，提示用户第m层搁架第n个托盘上摆放货品有误，请将其摆放至正确位置，同时可以发送报警信息至后台人员，以调用开门后的全程视频，确认用户是否有破坏、置换货品等不良行为。

在本公开的一些实施例中还提出一种非临时性计算机可读存储介质，其上存储有计算机程序，计算机程序被执行时实现第一方面实施例的无人售货设备的售货方法。
下面参照附图描述根据本公开第二方面实施例的无人售货设备。
图4是根据本公开实施例的无人售货设备的框图，图5是根据本公开的一个实施例的无人售货设备的前视图，图6是针对图5的无人售货设备的侧视图，参见图4-6所示，本公开实施例的无人售货设备100包括设备本体10、门体20，安装在设备本体10内的至少一层搁架30、称重装置40、提示装置50和处理装置60。其中，门体20可以为透明，便于看见设备本体10内的货品；以及，还包括安装于门体20上可以开关门体20的门把手11、由处理装置60控制可以保持门体关闭的锁12，锁12的主体部分安装在设备本体10上，锁扣安装在门体20上。
称重装置40设置在搁架30底部，用于采集售货前后搁架30上货品的重量；处理装置60与称重装置40相连，用于计算售货前搁架30上货品的重量与售货后搁架30上货品的重量的变化差值，并在变化差值小于第一重量变化阈值时发出提示控制信号，其中，第一重量变化阈值小于或等于零，即售货后搁架上后的重量比售货前搁架上货品的重量大，售货后搁架上货品重量增加。
提示装置50与处理装置60相连，用于根据提示控制信号进行报警提示。
在本公开的实施例中，如果售货前后搁架上货品的重量的变化差值小于第一重量变化阈值，则判定用户可能将不是某个搁架或托盘的货品放置在了该搁架或托盘，可能是将其他搁架或托盘上的货品放错，或者，也可能用户放入了新的货品，此时，进行报警提示， 可以提示用户将货品摆放到正确的位置，同时可以发送报警信息给后台工作人员，以便于调用开门后的全程视频，进一步确认是否发生用户故意破坏、置换商品等不良行为。
根据本公开实施例的无人售货设备100，不依赖于货品的RFID标签，通过称重装置40采集售货前后搁架30上货品的重量，处理装置60根据售货前后货品的重量的变化来判断货品是否被错放或被置换，并通过提示装置60及时进行报警提示，可以保证后续售货流程的正确执行，保障商家和用户的利益，成本低，更加易于普及。
在本公开的一些实施例中，如图5或6所示，本公开实施例的无人售货设备100还包括摄像装置70，摄像装置70与处理装置60相连，用于采集售货前后搁架上货品的图像；处理装置60还用于根据图像判断售货前后搁架30上货品的变化，并在根据图像判断售货前后搁架30上货品增加时发出提示控制信号，提示装置50进行报警提示。具体地，根据图像判断售货前后搁架30上货品重量增加时，认为用户将货品错放或置换或其他不良行为，及时进行报警提示，可以避免商家损失，提高购物安全。
在本公开的实施例中，处理装置60还用于，在售货前后搁架30上货品的重量的变化差值大于第二重量变化阈值时，其中，第二重量变化阈值大于或等于零，即货品重量减少，则判定用户取走该搁架30的货品，根据变化差值获得第一售货信息。具体地，在实施例中，规定预先按照类别将货品放置在搁架30或托盘上，因而，可以根据货品位置确定售货品类，例如，根据货品放置的搁架30或托盘，可以根据预存信息获得对应该搁架30或托盘上的货品的相关信息例如品类、单位货品重量、单价等，即基于发生重量变化的货品位置可以确定售货品类；以及，根据重量差和售货品类的预设单位货品重量获得售货数量，重量差与该售货品类的预设单位货品重量的商值即为售出品类货品的数量，为了避免该品类货品单位重量的偏差，商值可以四舍五入取其整数值。

如图7所示，为根据本公开的一个实施例的称重装置采集托盘上货品重量的示意图，每层搁架30摆放至少一个托盘31，例如搁架1包括托盘1-托盘4，并给每个托盘31进行不同序号编码，每个托盘31底部摆放至少一个称重装置40例如压力传感器，例如包括称重装置1-称重装置4。每个托盘31上摆放的商品仅为一种品类和重量，不允许同一个托盘31内摆放同一重量但不同品类的商品。其中，同一品类的商品的不同实物的实测重量，允许有误差Kn，Kn为每个托盘31上货品的标准重量Zn与实测重量之间的允许误差，0≤Kn≤Zn，Zn为序号为n的托盘31内的单个商品预置的标准重量，Kn的大小可以根据实际情况进行设定，也可以不进行设定，可以默认Kn＝0。
处理装置60预存有各个托盘31放置货品的相关信息，根据第n个托盘的设定识别码可以获得售货品类；以及，根据售货前后每个托盘31上货品的重量的变化差值和对应托盘的售货品类的预设单位货品重量获得售货数量，售货数量即用户选购的该品类货品的数量。
在一些实施例中，处理装置60还用于，在根据图像判断售货前后搁架上货品减少时根据图像的变化获得第二售货信息。具体地，如果货品减少，则判定用户从第m层搁架上取走货品，并在货品减少时根据图像变化获得减少货品的品类和数量，例如包括但不限于货品的颜色、种类、名称、体积和数量等，也就是用户选择货品的相关信息。
在本公开的实施例中，处理装置60在第一售货信息和第二售货信息不一致时发出提示控制信号。具体地，如果根据售货前后搁架上货品的重量变化判断的售货品类和数据，与根据图像识别来获得的售货品类和数量不一致，则认为有可能用户将货品放错位置或者置换了货品，此时进行报警提示，可以对用户进行提示，以便于将货品放置至正确的位置，保证后续程序的正常执行，同时可以发送报警提示信息至后台人员以查看是否发生恶意行为，保证商家利益。
在一些实施例中，处理装置60还用于，在第一售货信息与第二售货信息一致时，将第一售货信息或第二售货信息确定为最终售货信息。具体地，将通过称重获取的售货信息和通过图像识别获得的售货信息进行比较，例如，比对第m层搁架上第n个托盘上减少的货品数量Xn与图像识别出来减少的货品信息是否一致，如果第一售货信息与第二售货信息一致，则判定用户从m层搁架上取出了第n托盘上的货品，售货数量为Xn，输出用户购买的商品品类、数量和总价格，总价格满足：

在一些实施例中，摄像装置70的启动的触发信号为关门信号时，可以拍摄静态图像，并上传至处理装置60，处理装置60进行图像处理，对比两次连续关门信号时拍摄的各层搁架30的静态图片，进而确认用户取走的货品；如果摄像装置70的启动触发信号为开门信号，在检测到开门信号时，摄像装置70可以进行动态拍摄视频，用以监控用户购物期间的行为，当有报警信号时，确认是够有破坏、置换货品等不良行为，以排查警报原因。
在一些实施例中，摄像装置70设置在门体20内部，用于拍摄搁架30上货品的图像或 视频，也可以用于在门体20开启之后对用户行为进行监控。其中，可以在每层搁架30的对应门体位置或者搁架30的上方或左侧或右侧或右上角或左上角设置至少一个摄像装置70，或者，由一个摄像装置70采集多层搁架上货品的图像。
在本公开的实施例中，重量变化判定和图像比对的步骤可以同时进行，也可以按照前后顺序有所调整。例如，在开门时拍照或者视频，关门拍摄并检测重量变化；也可以是，在关门时同时进行拍照和检测重量变化；还可以是在关门后，先检测重量变化，若有变化，再检查图像识别的结果，判断是否有变化；还可以是，先通过图像识别判断图像有变化，再调出重量变化，以判断数量的变化。
在一些实施例中，如图8所示，无人售货设备100还包括用户信息读取装置90，用户信息读取装置90与处理装置60相连，用于读取用户信息，便于进行购买支付。例如，采用智能移动终端扫描二维码；或者，采集用户的生物体征信息例如用户的指纹信息、掌纹信息、掌静脉信息、指静脉信息、眼虹膜信息或者人脸信息。
