图2是根据本说明书一些实施例所示的基于区块链的目标对象盘点方法的示例性流程图。如图2所示，流程200可以包括步骤202～步骤208。
步骤202，获取用于触发目标对象盘点智能合约的触发指令，所述目标对象盘点智能合约存放于区块链的多个节点上，所述目标对象盘点智能合约包括盘点方法。步骤202可以由获取模块410执行。
在一些实施例中，目标对象可以是指仓库中所存放的商品。智能合约是指一种旨在以信息化方式传播、验证或执行合同的计算机协议。智能合约允许在没有第三方(例如，被交易物品的拥有者)的情况下进行可信交易，这些交易可追踪且不可逆转。
所述目标对象盘点智能合约可以是指以盘点目标对象为协议内容的智能合约。盘点目标对象可以是指对仓库中的商品数量、位置等信息进行清查、清点。
所述触发指令可以用于触发智能合约内容的执行。触发指令可以是盘点请求，第三方(例如，商品拥有者、拥有权限的用户)可以通过发起盘点请求来触发智能合约的执行。智能合约执行时，可以按照其中所包括的盘点方法对仓库中存放的目标对象进行盘点。第三方可以从区块链网络中的任何一个节点登录，然后发起盘点请求，并将盘点请求广播区块链网络中，区块链网络中的任何一个节点都可以对盘点请求进行处理。
在一些实施例中，所述盘点方法可以是指利用目标仓库中的智能设备，按照预设盘点方式采集目标仓库中的商品信息。其中，预设盘点方式可以包括对目标仓库中的所有商品依次进行盘点和/或对目标仓库中的部分商品(例如，商品信息发生变化的部分)进行盘点。关于盘点方法的更多描述可以参考图3的详细描述，此处不再赘述。
在一些实施例中，目标对象盘点智能合约存放于区块链的多个节点上，其中，区块链的节点可以是服务器、终端(例如，PC终端、手机、平板电脑等)、仓库等，或其任意组合。例如，区块链的多个节点中，一部分节点可以是服务器，一部分节点可以是终端，一部分节点可以是仓库。具体地，可以将仓库中所包括的各种设备共同作为区块链网络中的一个节点，例如，仓库节点中可以包括对仓库中的商品进行盘点的设备，例如，(RFID，Radio Frequency Identification)读取器、标签或二维码读码器、物联网(LOT，The Internet of Things)设备(例如，监控摄像头、传感器等)，以及计算设备，例如，计算机、服务器、智能终端(手机、平板电脑)等。
在一些实施例中，获取模块410可以通过网络(例如，网络120)从区块链的任一 个节点处获取触发指令，触发指令可以通过第三方手动输入、语音输入等方式发起。
在一些实施例中，在获取用于触发目标对象盘点智能合约的触发指令之前，可以在将所述目标对象存入目标仓库时，创建对应于该目标对象的目标对象盘点智能合约。目标仓库，可以是指存放所述目标对象的仓库，目标仓库作为区块链网络中的一个节点，使得第三方可以从区块链的任一节点发起对目标仓库中的目标对象进行盘点的智能合约。
示例性地，可以采用以下方式创建对应于该目标对象的目标对象盘点智能合约：目标对象在通过仓库入口入库后，仓库的智能设备(自动扫码器、RFID读卡器等)通过自动登记目标对象的商品信息，创建当前存入仓库的目标对象的智能合约，并将该仓库的节点地址(仓库所拥有的公钥)、商品信息(商品数量、类别、入库时间等)、以及在区块链上存储所述目标对象盘点智能合约的地址等信息一起绑定至所述智能合约中，然后将所述目标对象盘点智能合约广播至区块链的所有节点。其中，目标对象盘点智能合约中所绑定的商品信息可以是单一种类商品的信息，也可以是存入仓库的一个批次的多个种类的商品的信息，本实施例对此不做限定。
在创建目标对象盘点智能合约后，目标仓库节点可以定时对库中的目标对象进行数据采集，例如，记录当前时间的摄像头采集到的仓库照片、通过传感器采集库内各个区域所放置的商品的重量，并将采集结果上传到区块链上进行保存。
步骤204，响应于所述触发指令，触发所述目标对象盘点智能合约执行。步骤204可以由触发模块420执行。
在一些实施例中，可以由区块链网络中的任何一个节点响应于所述触发指令，执行所述目标对象智能合约。例如，区块链网络中包括服务器节点、终端节点以及仓库节点，第三方可以通过从终端节点登录后，发起盘点请求，盘点请求通过网络发送到服务器节点和目标仓库节点，最终由目标仓库节点响应于盘点请求，触发目标对象盘点智能合约的执行。执行目标对象盘点智能合约可以是指按照目标对象盘点智能合约中所包括的盘点方法对目标仓库中的商品进行盘点。
如前文所述，在第三方如目标仓库中目标对象的拥有者需要对目标仓库中的目标对象进行盘点时，可以由区块链中的任一节点触发所述目标对象盘点智能合约的执行，收到触发指令的节点将执行盘点操作，其他节点可以对盘点结果进行验证。例如，可以由区块链中的目标仓库节点执行所述目标对象盘点智能合约。
步骤206，基于被执行的所述目标对象盘点智能合约的所述盘点方法，对目标仓库中的目标对象进行盘点，得到所述目标仓库中目标对象的盘点信息。步骤206可以由盘点模块430执行。
在一些实施例中，盘点信息可以是指对目标仓库中的商品进行盘点后得到的商品数量、重量、商品位置等信息。例如，经过盘点可以得知商品的数量减少了多少、增加了多少、还剩余多少、商品之前所存放的位置、盘点时所存放的位置等。在一些实施例中，可以通过目标仓库中的智能设备对目标仓库中的目标对象进行盘点，例如，使用图像采集设备采集商品图像、使用重量传感器采集商品的重量、使用扫码设备(比如，RFID读卡器、扫码机)对商品进行扫码采集商品信息等，进而确定目标仓库中目标对象的变化数量，得到所述盘点信息。在采集商品信息可以有人工进行，也可以由机器人自动进行。
如步骤204中所述，目标仓库节点按照所述盘点方法执行一次盘点的过程可以如下文实施例所示：目标仓库节点可以在存储在区块链上找到在当前时刻之前采集的目标对象的图像信息、重量信息等，然后基于图像信息、重量信息对需要进行盘点的区域进行潜在子区域的识别，确定出需要精细盘点的子区域。然后使用库中的智能设备对需要进行精细盘点的子区域中的商品进行盘点，例如，使用RFID读卡器、扫码机设备精确的采集商品信息。关于子区域的确定和商品的盘点的更多描述可以在本说明书的其他地方找到，例如，图3及其相关描述，此处不再赘述。
步骤208，将所述盘点信息存储至所述区块链的多个节点上。步骤208可以由存储模块440执行。
在一些实施例中，存储模块440可以通过网络(例如，网络120)将盘点信息存储到区块链网络的多个节点中，多个节点都可以对所述盘点信息进行验证和存储。区块链网络中的其他节点(目标仓库节点以外的节点)可以对接收到的盘点信息进行验证分析，例如，对盘点信息进行重新计算，确定目标对象的变化数量是否一致等，验证一致则对盘点信息进行存储，从而确保盘点信息数据的真实性，同时第三方也可以从区块链网络中的任一节点对盘点信息进行查验。同时，由于将目标仓库作为区块链网络中的一个节点，因此，在目标仓库节点执行智能合约获得盘点信息后，可以直接将盘点信息广播至区块链网络中。
在一些实施例中，在对目标仓库中的目标对象进行盘点，得到盘点信息后，将所述盘点信息存储至区块链的多个节点之前，还可以验证所述盘点信息是否来自于所述目 标仓库中的目标对象，以确保存储至区块链中的盘点信息是来自目标仓库中的商品的信息，而不会是其他仓库中的商品。
示例性地，可以采用下文实施例所描述的方式来验证盘点信息是来自于目标仓库中的目标对象。
可以获取盘点信息的签名信息。签名信息可以是指利用目标仓库所拥有的私钥、设备编号对盘点信息进行签名运算得到。例如，可以使用目标仓库的私钥对盘点信息进行哈希运算，得到一个哈希值，该哈希值即为所述签名信息。其中，目标仓库所拥有的私钥、设备编号可以是指目标仓库中用于获取盘点信息的智能设备的私钥、设备编号。区块链网络中的其他节点在收到盘点信息后，可以对盘点信息中的签名进行验证，确保盘点信息确实是由目标仓库中的智能设备获取的盘点信息。具体地，区块链中的节点在接收到盘点信息之后，可以利用目标仓库的公钥(即，绑定在智能合约中的节点地址)对签名信息进行解密，得到解密信息，若所述解密信息与该盘点信息相同，则确认该盘点信息来自于所述目标仓库中的目标对象。在一些实施例中，还可以对解密得到的盘点信息进行分析(例如，对盘点信息进行计算、将盘点信息与上一次存储的商品信息进行比对)，进而验证盘点信息的真实性。
在将盘点信息存储至区块链上之后，第三方可以从区块链的任一节点处对盘点信息进行查询。例如，第三方可以通过从服务器登录来查询区块链中的盘点信息，也可以通过从终端登录来查询区块链中的盘点信息。
应当注意的是，上述有关流程200的描述仅仅是为了示例和说明，而不限定本说明书的适用范围。对于本领域技术人员来说，在本说明书的指导下可以对流程200进行各种修正和改变。然而，这些修正和改变仍在本说明书的范围之内。
图3是根据本说明书一些实施例所示的获取盘点信息的示例性流程图。如图3所示，流程300可以包括步骤302～步骤304。
步骤302，确定所述目标仓库中目标对象的库存发生变化的子区域。
在一些实施例中，目标对象的库存可以是指在当前时刻(例如，目标对象盘点智能合约的触发时刻)目标仓库中所存储的商品余量。子区域，可以是指将目标仓库按照一定方式划分后的所得到的区域，例如，可以将目标仓库以网格的形式进行划分，划分后的一个格子区域即为一个子区域；也可以将目标仓库按照商品的存放位置划分为多个子区域，例如，按照存放商品的类型进行划分，A类商品所在区域为一个子区域、B类 商品所在区域为一个子区域；再如，按照商品大小存放区域进行划分，大件商品存放区域为一个子区域、小件商品存放区域为一个子区域等。
库存发生变化的子区域可以是指所存储的商品的数量、位置、重量等信息发生了变化的区域。可以定时获取目标仓库中目标对象的设备采集信息，可以预定采集时间，在到了预定采集时间时自动获取目标对象的设备采集信息；也可以设置采集间隔时间，每间隔一定时间，获取一次目标对象的设备采集信息。并将所述设备采集信息存储至所述区块链的多个节点，其中，设备采集信息包括图像信息和/或重量信息。可以在智能合约中存储设备采集信息的存储地址，进而方便获取设备采集信息。可以通过对图像信息和/或重量信息来进行分析比对，确定目标仓库中目标对象的库存发生变化的子区域。具体地，可以从区块链的任一节点获取所述设备采集信息，设备采集信息可以是指利用目标仓库中的设备采集得到的商品信息，例如，使用图像采集设备采集得到的商品图像信息，使用重量采集设备采集得到的商品重量信息。并可以基于该设备采集信息确定目标仓库中目标对象的库存发生变化的子区域。例如，可以将采集的图像信息中的多个区域划分出子区域，可以根据当前盘点前两次采集的图像的子区域位置进行比较，当相同子区域位置内的商品比较后不一致时，说明库存发生变化。再例如，可以根据设备采集的重量信息中，将当前盘点前两次采集的子区域内(子区域可以是提前划分好的)的商品重量进行比较，当重量变化超过阈值时，说明库存发生变化。其中，阈值可以是重量比例，例如，当前子区域内商品重量的百分之5、百分之10、百分之20，也可以是固定重量值，例如，5kg、10kg、100kg等。
步骤304，对所述子区域中的目标对象进行盘点，以获取所述子区域中的目标对象的盘点信息。
在一些实施例中，在确定了库存发生变化需要进行盘点的子区域后，可以按照目标对象盘点智能合约中的盘点方法对子区域中的目标对象进行盘点。
盘点流程可以如下文实施例所示，下文实施例中以采集的图像信息为例进行了说明，应当理解，以下例子仅为示例性地说明盘点流程，并不旨在对盘点方式进行限制，例如，还可以以采集的重量信息进行盘点，也可以综合利用图像信息和重量信息进行盘点。
首先，在目标对象盘点智能合约被触发执行时，可以在该智能合约中找到存储的商品信息，然后基于上次盘点后到当前时刻最后一次盘点之间的所有商品信息中的图像信息对需要盘点的区域进行潜在子区域的识别，对所有图像信息中的区域进行划分。例 如，可以使用机器学习等算法进行识别，找到图像信息中的每个子区域。将子区域与上次盘点时的图像中的相同子区域的图像进行对比，确定出图像发生变化的子区域，作为需要进行精细盘点的区域。以此可以减少需要盘点的候选子区域的数量，提高盘点效率。其次，对确定出需要进行精细盘点的子区域，可以根据实际情况，进行自动或手动方式进行盘点。其中，自动盘点方式可以包括使用无人机或者移动机器人等智能设备携带RFID读卡器、扫码机等采集设备，对确定的子区域进行巡视，在巡视过程中采集子区域内的商品信息，得到盘点信息。手动方式可以包括人工手持RFID读卡器、扫码机等设备，对确定的子区域进行巡检扫码采集子区域内的商品信息，得到盘点信息。
应当注意的是，上述有关流程300的描述仅仅是为了示例和说明，而不限定本说明书的适用范围。对于本领域技术人员来说，在本说明书的指导下可以对流程300进行各种修正和改变。然而，这些修正和改变仍在本说明书的范围之内。例如，对本说明书有关流程步骤的改变，如步骤302和步骤304可以并行，在各步骤之间添加其他步骤(如，预处理步骤、存储步骤)等。

本说明书实施例可能带来的有益效果包括但不限于：(1)目标对象的盘点过程是在指定时间点触发和执行，盘点信息不会是提前盘点好后期上传的，使得商品拥有者可以获得当前的盘点信息，更加准确；(2)可以从区块链网络中的任一节点触发智能合约的执行、验证，提高了盘点的成功率和安全性；(3)在盘点时，综合利用目标仓库中的设备，融合多种传感数据，将盘点范围进行缩小，提高了盘点效率；(4)结合带有签名功能的智能设备和区块链智能合约功能，可以保证盘点信息的采集、计算、存储是可信的，从而满足第三方对商品盘点的可信需求。需要说明的是，不同实施例可能产生的有益效果不同，在不同的实施例里，可能产生的有益效果可以是以上任意一种或几种的组合，也可以是其他任何可能获得的有益效果。
上文已对基本概念做了描述，显然，对于本领域技术人员来说，上述详细披露仅仅作为示例，而并不构成对本说明书的限定。虽然此处并没有明确说明，本领域技术人员可能会对本说明书进行各种修改、改进和修正。该类修改、改进和修正在本说明书中被建议，所以该类修改、改进、修正仍属于本说明书示范实施例的精神和范围。
同时，本说明书使用了特定词语来描述本说明书的实施例。如“一个实施例”、“一实施例”、和/或“一些实施例”意指与本说明书至少一个实施例相关的某一特征、结构或特点。因此，应强调并注意的是，本说明书中在不同位置两次或多次提及的“一实施例”或“一个实施例”或“一个替代性实施例”并不一定是指同一实施例。此外，本说明书的一个或多个实施例中的某些特征、结构或特点可以进行适当的组合。
此外，本领域技术人员可以理解，本说明书的各方面可以通过若干具有可专利性的种类或情况进行说明和描述，包括任何新的和有用的工序、机器、产品或物质的组合，或对他们的任何新的和有用的改进。相应地，本说明书的各个方面可以完全由硬件执行、可以完全由软件(包括固件、常驻软件、微码等)执行、也可以由硬件和软件组合执行。以上硬件或软件均可被称为“数据块”、“模块”、“引擎”、“单元”、“组件”或“系统”。此外，本说明书的各方面可能表现为位于一个或多个计算机可读介质中的计算机产品，该产品包括计算机可读程序编码。
计算机存储介质可能包含一个内含有计算机程序编码的传播数据信号，例如在基带上或作为载波的一部分。该传播信号可能有多种表现形式，包括电磁形式、光形式等，或合适的组合形式。计算机存储介质可以是除计算机可读存储介质之外的任何计算机可读介质，该介质可以通过连接至一个指令执行系统、装置或设备以实现通讯、传播或传输供使用的程序。位于计算机存储介质上的程序编码可以通过任何合适的介质进行传播，包括无线电、电缆、光纤电缆、RF、或类似介质，或任何上述介质的组合。
本说明书各部分操作所需的计算机程序编码可以用任意一种或多种程序语言编写，包括面向对象编程语言如Java、Scala、Smalltalk、Eiffel、JADE、Emerald、C++、C#、VB.NET、Python等，常规程序化编程语言如C语言、Visual Basic、Fortran 2003、Perl、COBOL 2002、PHP、ABAP，动态编程语言如Python、Ruby和Groovy，或其他编程语言等。该程序编码可以完全在用户计算机上运行、或作为独立的软件包在用户计算机上运行、或部分在用户计算机上运行部分在远程计算机运行、或完全在远程计算机或服务器上运行。在后种情况下，远程计算机可以通过任何网络形式与用户计算机连接，比如局域网(LAN)或广域网(WAN)，或连接至外部计算机(例如通过因特网)，或在云计算环境中，或作为服务使用如软件即服务(SaaS)。
此外，除非权利要求中明确说明，本说明书所述处理元素和序列的顺序、数字字母的使用、或其他名称的使用，并非用于限定本说明书流程和方法的顺序。尽管上述披露中通过各种示例讨论了一些目前认为有用的发明实施例，但应当理解的是，该类细节仅起到说明的目的，附加的权利要求并不仅限于披露的实施例，相反，权利要求旨在覆盖所有符合本说明书实施例实质和范围的修正和等价组合。例如，虽然以上所描述的系统组件可以通过硬件设备实现，但是也可以只通过软件的解决方案得以实现，如在现有的服务器或移动设备上安装所描述的系统。
同理，应当注意的是，为了简化本说明书披露的表述，从而帮助对一个或多个发明实施例的理解，前文对本说明书实施例的描述中，有时会将多种特征归并至一个实施例、附图或对其的描述中。但是，这种披露方法并不意味着本说明书对象所需要的特征比权利要求中提及的特征多。实际上，实施例的特征要少于上述披露的单个实施例的全部特征。
一些实施例中使用了描述成分、属性数量的数字，应当理解的是，此类用于实施例描述的数字，在一些示例中使用了修饰词“大约”、“近似”或“大体上”来修饰。除非另外说明，“大约”、“近似”或“大体上”表明所述数字允许有±20％的变化。相应地，在一些 实施例中，说明书和权利要求中使用的数值参数均为近似值，该近似值根据个别实施例所需特点可以发生改变。在一些实施例中，数值参数应考虑规定的有效数位并采用一般位数保留的方法。尽管本说明书一些实施例中用于确认其范围广度的数值域和参数为近似值，在具体实施例中，此类数值的设定在可行范围内尽可能精确。
针对本说明书引用的每个专利、专利申请、专利申请公开物和其他材料，如文章、书籍、说明书、出版物、文档等，特此将其全部内容并入本说明书作为参考。与本说明书内容不一致或产生冲突的申请历史文件除外，对本说明书权利要求最广范围有限制的文件(当前或之后附加于本说明书中的)也除外。需要说明的是，如果本说明书附属材料中的描述、定义、和/或术语的使用与本说明书所述内容有不一致或冲突的地方，以本说明书的描述、定义和/或术语的使用为准。
最后，应当理解的是，本说明书中所述实施例仅用以说明本说明书实施例的原则。其他的变形也可能属于本说明书的范围。因此，作为示例而非限制，本说明书实施例的替代配置可视为与本说明书的教导一致。相应地，本说明书的实施例不仅限于本说明书明确介绍和描述的实施例。
