Description

货架、货品识别方法及电子设备 技术领域
本发明涉及一种用于零售业的货品堆放装置，具体地说，涉及一种货架、一种货品识别方法及一种用于实现货品识别的电子设备。
背景技术
传统零售业的购物方式，每一家超市或便利店需要有专职的配货人员，人力成本较高。随着电子支付技术、身份感知技术及云计算技术的发展，无人检测技术具备很高的可行性。
在无人超市或无人便利店的解决方案中，计算机要持续监控每一次购物行为的发生，需要解决如下几个问题：一是货品识别问题，需要识别被取走或被放回的货品的种类和数量，进而根据该种类货品的单价计算其价格；二是用户身份识别问题，需要判断取走或放回该货品的用户身份，将用户身份与其取走或放回的货品建立或解除匹配关系，进而形成和更新该用户的电子购物车，以便进行结算。
针对此类问题，现有技术中存在一种可感知货品的货架，参见中国专利CN108497839A，需在货架内设置大量的传感器用于检测，在每一层货架中设有多个并列的托盘，在每一个托盘下均需对应设置至少一重量传感器。该方案的不足之处在于，货架的每一个托盘的尺寸是固定的，不能调节托盘的宽度，放置于托盘上的货品宽度受到限制；当需要摆放的货品的尺寸大于托盘的宽度时，只能更换原货架，如果一家便利店需要销售尺寸差异较大的多种商品，就要准备多种不同尺寸的托盘，管理不便，运营和维护成本较高。其次，货架的每一层需要多个托盘和多个重量传感器，导致货架的成本较高，不利于市场竞争和推广应用。

如图1、图2所示，本实施例提供一种货架100，包括货架支架1以及至少一货架板2，每一货架板2包括一托板21、一托盘22、第一重量感应装置23、第二重量感应装置24以及栏位装置25。货架100可以被安装于一冰箱或冰柜内。托盘22用以放置货品，本实施例货架100上放置的货品需要便于用户取走或放回，因此，以货架100或托盘22朝向用户的一端为前端，远离用户的一端为后端。本实施例优选栏位装置25的前端高度低于其后端的高度，以便于用户在托盘22内拿取或放置货品。
本实施例中，托板21可拆卸式或可固定式安装至货架支架1上。本实施例优选托板21可拆卸式安装至货架支架1上。具体如图1、图2所示，货架支架1包括支架本体11以及支架卡口12，支架本体11为竖直设置的长条形长方体；支架卡口12下凹于支架本体11的一侧壁；支架卡口12沿直线均匀分布于长条形的支架本体11上。每一托板21包括托板本体211以及卡爪212，卡爪212设于托板本体211一端边缘处，且可拆卸式卡合至支架卡口12，使得货架板2可拆卸式安装在支架本体11上。更具体的，托板本体211左右两侧包括横托板2111，横托板2111的后端设有卡爪212，当卡爪212卡合至支架卡口12时，托板本体211的上边缘或下边缘垂直于支架本体11的侧壁。

第一支架251的下端插入至第一排孔41，第一支架251包括第一限位孔51；第二支架252的下端插入至第二排孔42，第二支架252包括第二限位孔52；第三支架253的前端穿过第一限位孔51且插入至第一排孔41，其后端穿过第二限位孔52且插入至第二排孔42，第三支架253的前端、后端分别可插拔式安装至第一支架251、第二支架252，第一限位孔51、第二限位孔52用以固定第三支架253，使得第三支架253在前后方向上无法偏转，保持相对稳定，至少一第三支架253就可以将托盘22分成多个栏位，每个栏位用于摆放同一种类的货品。
用户可以随时将至少一第三支架253从原位置拔出，插入至另一位置，从而可以根据实际需求调整每一栏位的宽度，使得栏位的宽度与需要摆放的货品尺寸相对应。
更具体的，第一支架251包括两根水平设置的第一横杆2511，两根第一横杆2511之间形成第一限位孔51；第一支架251底部设有两个以上的支脚2512，插入至第一排孔41；第二支架252包括两根水平设置的第二横杆2521，两根第二横杆2521之间形成第二限位孔52；第二支架252底部设有两个以上的支脚2512，插入至第二排孔42；第三支架253包括至少一根横梁2531，从前端延伸至后端，包括前后两个支脚2512，前支脚2512插入至第一排孔41，后支脚2512插入至第二排孔42，从而实现固定第三支架253。
前述三种支架底部的支脚2512都是插入至第一排孔41和/或第二排孔42的，可以理解的是，为了保证支脚2512在插入排孔后的稳定性，可以考虑增 大支脚在排孔内的插入深度，防止前述支架发生晃动。进一步地，货架100还包括第四支架254，直接或间接地连接至托盘22或托板21；第四支架254包括安装板2541以及第三排孔43；安装板2541平行设于托盘22下方；第三排孔43贯穿于安装板2541，且与第一排孔41或第二排孔42相对设置。优选地，第四支架254具有一定厚度，如1-5厘米，能更好地固定第三支架253。优选地，第四支架254与第一支架251或第二支架252之间具有一定距离，如1-5厘米，能更好地固定第三支架253。
如图3、图5所示，本实施例中，第四支架254的两端分别连接至一垫片27。优选地，第四支架254的长度与托盘22的长度相等，第四支架254卡设于左右两端托盘侧板221之间，使得第四支架254不能左右晃动，进而使得固定与第三排孔43上的第三支架253不能左右晃动，实现第三支架253的固定。第四支架254的横截面呈几字形，其包括安装板2541、U形支撑板2542和搭接板2543。U形支撑板2542用于连接安装板2541和搭接板2543，其上表面与托盘22的下表面贴合；搭接板2543与垫片27的第二连接面272的上表面贴合，使得托盘22的重量通过第四支架254传递到垫片27上，从而使得托盘22的重量被重量传感器接受并测量。
如图5所示，本实施例中，货架100还包括垫块28，垫块28设于安装板2541与托盘22之间；垫块28包括为长条形的垫块本体281以及第四排孔44，第四排孔44贯穿于垫块本体281，且与第一排孔41或第二排孔42相对设置。可以理解的是，第一排孔41、第二排孔42为第三排孔43和第四排孔44相贯穿形成。
第三支架253的固定方式具体为：第三支架253前端穿过第一限位孔51且插入至第一排孔41、前端的第四排孔44及第三排孔43，其后端穿过第二限位孔52且插入至第二排孔42、后端的第四排孔44及第三排孔43。这样的插 接方式使得第三支架253可以随时根据需求通过插拔方式进行每一栏位的尺寸大小的调整，便于栏位可根据货品尺寸需求进行调整。优选地，垫块28具有一定厚度，能更好地固定第三支架253。
其中，第一排孔41或第二排孔42或第三排孔43或第四排孔44包括两个以上通孔45，任意两个相邻通孔45的间距相同，任意两个相邻通孔45的直径相同。换句话讲，第一排孔41、第二排孔42、第三排孔43、第四排孔44的通孔45相等且等间距设置，这样便于第三支架253在尺寸不变情况下可以通用，便于第三支架253可以随时根据需求通过插拔方式进行每一栏位的尺寸大小的调整。
本实施例还包括数据处理系统3，连接至第一重量感应装置23及第二重量感应装置24，可以设置于货架100内部或外部，用以判断托盘22上被取走或被放回的货品的种类和数量，进一步还可以结合货品的单价来计算顾客需要支付的金额，以便于为顾客结算。数据处理系统3为一种电子设备，优选计算机，包括存储器和处理器；存储器用于存储可执行程序代码；处理器通过读取可执行程序代码来运行与可执行程序代码对应的程序。数据处理系统3包括处理器内的若干功能单元，当处理器运行某一前述程序时，某一功能单元用于实现与该程序对应的功能。

如图7所示，基于前文所述的货架，本发明还提供一种货品识别方法，其包括如下步骤S1-S8。
S1、货架设置步骤，设置一前文所述的货架100，在货架100的每一栏位上摆放有同一种类的货品；其中，同一种类的货品是指重量大致相同、单价相同的两个以上货品。
S2、数据录入步骤，录入托盘22的托盘22数据及被放置于托盘22上的每一货品的货品数据，托盘22数据包括托盘22的宽度A及托盘22上第i栏位的中心点位置Ai及栏位宽度Bi；货品数据包括每一货品的种类、单品重量、单品价格及其所处栏位。
S3、坐标轴设置步骤，在托盘22的横向上建立一维坐标轴，定义设有第一重量感应装置23的一端的坐标为0，定义设有第二重量感应装置24的一端的坐标为A，定义第i栏位的位置坐标范围为大于(Ai-Bi/2)且小于等于(Ai+Bi/2)；

S5、变化值计算步骤，实时计算第一重量感应装置23的重量感应值的变化值QX j＝X j-X (j-1)以及第二重量感应装置24的重量感应值的变化值QY j＝Y j-Y (j-1)。
S6、货品变动位置计算步骤，当QX j或QY j为非零数值时，计算货品数量发生变动的位置坐标M j＝(1–QX j/(QX j+QY j))*A。
S7、货品变动位置判定步骤，对比位置坐标M j与每一栏位的位置坐标范围，当M j大于(As-Bs/2)且小于等于(As+Bs/2)时，判定第s栏货品数量发生变动。
S8、货品种类判断步骤，根据货品数量发生变动的栏位及货品数据中每一货品的种类及其所处栏位判断被取走或被放回的货品的种类。
在上述步骤中，电子设备中的处理器运行可执行计算机程序，用以实现步骤S2～S8。
本实施例中，重量感应装置为重量传感器，在传感器上方的重量发生变动时，其感应值经常会发生波动，其波动时间是不确定的，传感器稳定后采集到的数值才是其真实的感应值。在所述重量感应值获取步骤S4中，第一重量感应装置23、第二重量感应装置24采集到的重量感应值包括稳定感应值和波动感应值；所述稳定感应值为一重量感应装置在稳定状态下采集到的重量感应值；所述波动感应值为一重量感应装置在波动状态下采集到的重量感应值。
如图8所示，本实施例中，电子设备中的处理器运行可执行计算机程序，执行所述重量感应值获取步骤S4，可以获取每一重量感应装置在每一次稳定状态下的重量感应值，具体包括如下步骤S41～S50。
S41、稳定感应值获取步骤，获取一重量感应装置在第m次稳定状态下的重量感应值为Vm。
S42、实时重量感应值采集步骤，连续多次采集该重量感应装置的实时重量感应值Wr，r为采集次数，采集频率优选为每秒70次。该重量感应装置的实时重量感应值Wr分别为W1、W2、W3、……、W70、W71、……。
S43、波动量计算步骤，连续多次计算实时波动量Dr＝Wr-Vm；Dr分别为D1、 D2、D3、……、D70、D71、……。
S44、循环设置步骤，定义计数器数值为p，从p＝1开始，循环执行如下步骤S45～S50，每循环一次，计数器数值加一。
S45、波动量选取步骤，用滑动窗口记录从Dp开始的n个连续波动量，从Dp至D (p+n-1)，n为预设的数值数量，20≤n≤60。本实施例优选n＝40，当p＝1时，滑动窗口记录D1、D2、D3、……、D40的数值。
S46、波动量比较步骤，比较所述连续n个(n＝40)波动量，记录其中的最大值Dn max和最小值Dn min。
S47、波动量差异值计算步骤，计算连续n个(n＝40)波动量的最大差异值Dn diff＝Dn max-Dn min；
S48、波动量差异值比较步骤，将Dn diff与一预设的波动量差异阈值作比较；所述波动量差异阈值为预设阈值，优选为1-3克，本实施例中为2克。
当差值Dn diff大于所述波动量差异阈值时，判断重量感应装置此时处于波动状态，返回所述波动量选取步骤S45，计数器数值加一；当Dn diff小于或等于所述波动量差异阈值时，判断重量感应装置此时处于稳定状态,执行下一步骤S49。
S49新稳定感应值计算步骤，计算n个实时重量感应值Wp至W (p+n-1)的平均值，记录为新稳定感应值W；当p＝1时，计算W1、W2、W3、……、W40的平均值，作为新稳定感应值W。
S50稳定感应值比较步骤，将新稳定感应值W与重量感应值Vm的差值与一感应值差异阈值作比较；当该差值大于所述感应值差异阈值时，判断新稳定感应值W为第(m+1)次稳定状态下的重量感应值V (m+1)；当该差值小于或等于所述感应值差异阈值时，判断新稳定感应值W为第m次稳定状态下的重量感应值Vm。返回所述波动量选取步骤S45，计数器数值加一。所述感应值差异阈值为一预设阈值，优选0.1克～10克，本实施例中选取2克。
在没有人从货架取走货品或放置货品的情况下，重量感应装置一般会长时间处于稳定状态下，稳定状态是一个连续的过程，重量感应装置的稳定感应值有可能在较长时间内都不会变化。上述方法判断出来的连续多个新稳定感应值W都与之前的稳定感应值Vm相等，此时可以忽略误差的影响，将连续出现的多个稳定感应值都认为是在同一次稳定状态下。当间隔至少一个波动感应值的两个相继出现的稳定感应值的差异较大时，认为这两个稳定感应值分属于相邻的两次稳定状态。
在上述步骤S41～S50中，货架的当前稳定值Vm，当前实时值Wr，计算实时差值Dr，Dr＝Wr-Vm。当货品被取走或放回时，会产生波动感应值，第一重量感应装置23、第二重量感应装置24实时采样频率为70Hz，即每秒70次采样实时差值Dr。用滑动窗口，连续记录与Vm最近的40个Dr值，记为D1、D2、……、D40。如果这40个Dr值的最大值与最小值的差值D 40diff不超过波动量差异阈值(如2克)，判断重量感应装置此时处于稳定状态，计算这40个值的平均值，记录为新稳定感应值W。若新稳定感应值W与重量感应值Vm差值小于2克，认为此时还处于第m次稳定状态下，新稳定感应值W近似于重量感应值Vm。若新稳定感应值W与重量感应值Vm差值大于2克，认为此时处于新稳定状态下，新稳定感应值W为第(m+1)次稳定状态下的重量感应值V (m+1)。如果40个Dr值的最大值与最小值的差值D 40diff超过波动量差异阈值，判断重量感应装置此时处于波动状态。
无论重量感应装置处于稳定状态还是波动状态，都要返回波动量选取步骤S45，循环执行步骤S45～S50，每循环一次，计数器加一，滑动窗口向后滑动一位。如p＝2时，滑动窗口记录D2、D3、……、D40、D41的数值；p＝3时，滑动窗口记录D3、D4、……、D41、D42的数值，等等。在其他实施例中，所述滑动窗口滑动位数可不限制为1位，也可不限定为连续40个，也可为合适的 其他数值。
值得注意的是，在所述货架设置步骤S1中，货架100设置完毕且为空置状态时，第一重量感应装置23、第二重量感应装置24在稳定状态下采集到的重量感应值为第1次稳定状态；在摆放货品过程中，在每一次摆放货品后依次为第2次稳定状态、第3次稳定状态……，直至货品摆放完毕。
在货架空置状态下，货架上一重量传感器的重量感应值即为第1次稳定状态下的稳定感应值V1，这是在货架设置完成后很容易测量到的数据。按照上述步骤S41～S50的方法，可以根据一重量传感器的第m次稳定状态下的重量感应值Vm，计算出第(m+1)次稳定状态下的重量感应值V (m+1)。根据递归法，计算机可以很容易获取重量传感器在每一次稳定状态下的稳定感应值。
如图7所示，本实施例中，所述货品识别方法还包括步骤：
S51、重量差值计算步骤，计算托盘22的重量变化数值Q＝(QX j+QY j)；
此时在货品种类判断步骤S8之后，还包括步骤S9-S10：
S9、单品重量获取步骤，根据被取走或被放回的货品的种类及货品数据中每一货品的种类及其单品重量获取被取走或被放回的货品的单品重量q；以及
S10、货品数量计算步骤，计算被取走或被放回的货品的数量N＝Q/q。
如图7所示，本实施例中，在货品种类判断步骤之后，还包括步骤S11-S12：
S11、单品价格获取步骤，根据被取走或被放回的货品的种类及货品数据中每一货品的种类及其单品价格获取被取走或被放回的货品的单品价格r；以及
S12、货品价值计算步骤，计算被取走或被放回的货品的价格R＝r*N。
数据处理系统3包括处理器，通过读取可执行程序代码来运行与可执行程序代码对应的程序，以执行前文所述货品识别方法中的至少一步骤，包括步骤S2-S12以及步骤S51。在步骤S2中录入托盘数据及货品数据是为了便于建立 初始的数据库；在步骤S3中通过设置坐标轴可实现将所述托盘数据与所述货品数据相匹配，可获知在任一托盘的任一栏位内的货品信息；在步骤S4-S7中，通过实时获取第一重量感应装置23及第二重量感应装置24的重量感应值，从而得知是哪一个托盘内的货品被取走或被放回，并能通过计算准确获取托盘的瞬时重量变化值以及货品变动位置的坐标，从而得知是哪一个栏位内的货品被取走或被放回；在步骤S8中根据该栏位内货品数据判断被取走或被放回的货品的种类；在步骤S51中通过计算托盘的重量变化数值获知被取走或被放回的货品的总重量；在步骤S9-S10中通过货品的单品重量计算得知被取走或被放回的货品的数量；在步骤S11-S12中通过货品的单品价格计算得知被取走或被放回的货品的价格。
本发明还提供一种电子设备，包括存储器和处理器；存储器用于存储可执行程序代码；处理器通过读取可执行程序代码来运行与可执行程序代码对应的程序，以执行货品识别方法中的至少一步骤。
本发明的有益效果在于，提供一种货架、货品识别方法及电子设备，在货架的每一层架板上仅设置一个托盘，并在托盘下方两端各设置一个或两个传感器即可实现货品感知功能，有效减少了传感器的数量，在保证实现货品感知功能的同时有效降低了货架的制造成本。该货架的栏位装置是可拆卸的，可以随时根据需求通过插拔方式进行每一栏位的尺寸大小的调整，便于栏位可根据用户需求调整每一栏位的尺寸，以适用于不同规格的货品。
以上仅是本发明的优选实施方式，使本领域的技术人员更清楚地理解如何实践本发明，这些实施方案并不是限制本发明的范围。对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
