为了更好的理解上述技术方案，下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
为了更好的理解上述技术方案，下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
参照图2，本申请第一实施例提供一种基于区块链的集中采购方法的流程示意图。该实施例中，所述基于区块链的集中采购方法包括以下步骤：
步骤S10，获取采购方的采购需求信息和销售方的销售信息；
本实施例中的基于区块链的集中采购方法应用于集中采购平台，集中采购平台包括商品模块（全品类行业标准SKU）、销售方模块、物流模块、交易大厅、订单模块、合同管理模块以及服务器。其中商品模块用于展示在行业标准下销售方所销售商品的规格、数量、价格等信息，以便集中采购平台获取多个销售方的销售商品信息，并结合采购方的采购商品信息进行交易匹配；销售方模块用于记录销售方对于商品数量与价格等信息的设定；物流模块用于交易后的物流信息追踪；交易大厅用于向采购方和销售方进行意见沟通，以决定是否进行交易；订单模块用于根据采购方提交的商品采购数量及价格，生成订单发送至集中采购平台；合同管理模块用于向进行交易的销售方和采购方提供智能合同；服务器与上述各模块进行通信连接，实现集中采购平台与各模块的连接，以便将每笔交易记录全流程关键信息记录在集中采购平台中，由于在区块链技术中，“去中心化”的特点使得节点信息能够同步更新，减少因信息不对称而造成经济效率的损失，所以本申请基于区块链技术构建的集中采购平台具有不可篡改、可追溯、去中心化、信息透明可信等特性，实现集中平台上参与方的信息真实可靠、公开透明。并且，基于区块链的集中采购平台兼顾了传统的点对点数据资源共享和信息资源中心两种模式的优点，既实现多企业多部门间的数据共享的功能，又实现去中心化、降低信任成本、数据备份和可追溯功能，实现阳光采购的有益效果。
进一步地，集中采购平台检测多个采购方发布的采购订单，并提取采购订单中的采购需求信息。进一步地，集中采购平台获取多个销售方发布的销售信息，以根据销售信息结合采购需求进行筛选。进一步地，获取采购方的采购需求信息和销售方的销售信息的步骤包括：
步骤S11，基于多个所述采购方发布的采购订单，获取多个所述采购方的采购需求信息，其中所述采购需求信息包括采购商品信息、采购数量信息以及采购价格信息；
步骤S12，获取多个所述销售方的销售信息，其中所述销售信息包括销售商品信息、销售数量信息以及销售价格信息。
进一步地，集中采购平台检测多个采购订单，提取多个采购订单中的采购需求信息，其中采购订单由订单模块根据多个采购方提交的商品采购数量及价格生成，采购需求信息包括采购商品信息、采购数量信息以及采购价格信息。进一步地，集中采购平台获取多个销售方在集中采购平台上发布的销售信息，以便根据采购需求信息和销售信息进行筛选，其中所述销售信息包括销售商品信息、销售数量信息以及销售价格信息。
步骤S20，基于所述采购需求信息和所述销售信息，进行交易撮合；
进一步地，交易撮合的方式包括单独采购方式和集中采购方式，集中采购平台检测发布采购订单的采购方数量，并根据检测到的采购方数量，确定交易撮合的方式，若采购方数量小于预设阈值，则采用单独采购方式进行交易撮合，其中预设阈值为集中采购平台设定，用于表征是否满足集中采购条件的数值。进一步地，若采购方数量大于或等于预设阈值，则采用集中采购方式进行交易撮合。可以理解地，进行交易撮合时，首先进入交易撮合队列，按照价格优先、数量优先、时间优先的顺序进行排序，以保证交易撮合过程中每笔订单都可以撮合出当前最优交易，降低采购方的采购成本。进一步地，在交易撮合过程同步记录日志，以便销售方和采购方进行追溯，因将记录的日志存储于由区块链技术构建的集中采购平台，又因为区块链技术具有不可篡改、可追溯、去中心化、信息透明可信等特性，实现去中心化、降低信任成本、数据备份和可追溯的有益效果。
步骤S30，向进行交易的所述采购方和所述销售方提供交易合同。
进一步地，与服务器进行通信连接的合同管理模块中设置有智能交易合同。进一步地，当采购方与销售方经过交易撮合，在交易大厅中进行沟通达成合作意向时，集中采购平台调用合同管理模块中的智能交易合同，并发送至采购方和销售方，以便双方通过智能交易合同完成交易。进一步地，向进行交易的所述采购方和所述销售方提供交易合同的步骤包括：
步骤S31，若进行交易撮合的所述采购方和所述销售方基于交易撮合选择执行交易，则根据所述采购方的采购需求信息和所述销售方的销售信息，拟制相应的交易合同；
步骤S32，将所述交易合同发送至选择执行交易的所述采购方和所述销售方，完成所述交易。
进一步地，集中采购平台检测到采购方和销售方在交易撮合下，双方都选择执行交易时，根据获取到的销售方的销售信息和采购方的采购需求信息，自动调用智能交易合同，拟制出相应的交易合同，并将交易合同发送至进行交易的采购方和销售方。集中采购平台在采购方和销售方签订交易合同后，自动确认并执行条款双方设置的条款，完成本次交易；同时，交易合同的所有改动和执行都会对所有与交易相关人士可视，极大的低合同风险和执行成本。
本申请实施例提出的一种基于区块链的集中采购方法、装置、设备及可读存储介质，应用于由区块链技术构建的集中采购平台，所述基于区块链的集中采购方法包括：获取采购方的采购需求信息和销售方的销售信息；基于所述采购需求信息和所述销售信息，进行交易撮合；向进行交易的所述采购方和所述销售方提供交易合同。本申请根据采购方的采购需求信息和销售方的销售信息，将信息匹配程度最高的采购方与销售方进行交易撮合，使得交易的每一笔订单都是当前最优交易，并且，因交易撮合由集中采购平台自动进行，减少人工干预，解决产品招投标不透明的问题，避免腐败现象的出现。此外，本申请通过向采购方与销售方提供交易合同，因交易合同自动生成并执行条款，降低合同风险和执行成本。
进一步地，基于本申请基于区块链的集中采购方法的第一实施例，提出本申请基于区块链的集中采购方法第二实施例，在第二实施例中，基于所述采购需求信息和所述销售信息，进行交易撮合的步骤包括：
步骤S21，检测发布采购订单的采购方数量是否大于或等于预设阈值；
步骤S22，若所述采购方数量小于预设阈值，则判定所述采购方数量不满足集中采购的条件，根据单独采购方式进行交易撮合；
步骤S23，若所述采购方数量大于或等于预设阈值，则判定所述采购方数量满足集中采购的条件，根据集中采购方式进行交易撮合。
进一步地，集中采购平台中存在预设阈值，其中预设阈值用于衡量采购方数量是否达到集中采购标准，并且预设阈值可由集中采购平台根据不同情况进行调整。进一步地，集中采购平台检测在该平台上发布采购订单的采购方数量，并确定采购方数量是否大于或等于表征达到集中采购标准的预设阈值。进一步地，若采购方数量小于预设阈值，说明采购方数量不满足进行集中采购的条件，则需要根据单独采购的方式对多个采购方与销售方进行交易撮合；若采购方数量大于或等于预设阈值，说明采购方数量满足进行集中采购的条件，则根据集中采购的方式对多个采购方与销售方进行交易撮合。例如，集中采购平台中的预设阈值为20，若采购方数量为15，则采购方数量不满足进行集中采购的条件，需要按照单独采购的方式对15个采购方与销售方进行交易撮合；若采购方数量为25，则采购方数量满足进行集中采购的条件，按照集中采购的方式对25个采购方与销售方进行交易撮合。进一步地，若所述采购方数量小于预设阈值，则判定所述采购方数量不满足集中采购的条件，根据单独采购方式进行交易撮合的步骤包括：
步骤S221，确定多个所述采购方的采购需求信息是否满足多个所述销售方中任一销售方的销售规则条件，其中所述销售规则条件为相同采购商品信息对应采购数量信息的数量总和大于目标阈值；
步骤S222，若满足多个所述销售方中任一销售方的销售规则条件，则将多个所述采购方的采购需求信息与满足所述销售规则条件的销售方匹配，完成交易撮合；
步骤S223，若不满足多个所述销售方中任一销售方的销售规则条件，则基于多个所述采购方的采购需求信息中的采购价格信息，将多个所述采购方的采购需求信息分别与多个所述销售方的销售信息进行匹配，完成交易撮合。
进一步地，单独采购方式为：在不满足集中采购的情况下，集中采购平台通过检测多个采购方中相同采购商品的采购数量总和是否达到多个销售方中任一销售方的销售规则条件，即销售方对对应销售商品进行价格调整的销售数量要求，进一步根据数量信息选择不同的匹配方案，其中匹配方案至少为两种，第一种为将多个所述采购方的采购需求信息与满足所述销售规则条件的销售方匹配；第二种为将多个所述采购方的采购需求信息分别与多个销售方的销售信息进行匹配。进一步地，集中采购平台根据从多个采购方发布的采购订单中获取的采购需求信息，并从商品模块获取多个销售方销售的商品规格、数量、价格等销售信息，计算出多个采购方采购需求信息中相同采购商品的采购数量总和，并确定采购数量总和是否大于或等于多个销售方中任一销售方对对应销售商品进行价格调整的销售数量要求。进一步地，若多个采购方的采购数量的总和大于或等于多个销售方中任一销售方对对应销售商品进行价格调整的销售数量要求，则按照第一种方案将多个所述采购方的采购需求信息与满足所述销售规则条件的销售方匹配，以根据匹配的数量信息得到销售商品的价格优惠，降低采购方的采购成本；若多个采购方的采购数量的总和小于多个销售方中所有销售方对对应销售商品进行价格调整的销售数量要求，则按照第二种方案将多个所述采购方的采购需求信息分别与多个销售方的销售信息进行匹配，为采购方匹配价格最接近的销售方。例如：存在任一销售方承诺，当采购方的采购电脑数量达到100台时，对电脑的价格进行相应下调。进一步地，当多个采购方采购电脑的数量总和大于或等于100台时，则将多个采购方的电脑采购订单组成一个订单，并由集中采购平台进行交易撮合，以得到销售方在规定数量下的价格优惠；当多个采购方采购电脑的数量总和小于100台时，则将多个采购方的电脑采购订单分别与多个销售方的电脑销售信息进行对比，匹配出与多个采购方的电脑采购价格最接近的销售方，并由集中采购平台进行交易撮合，以便将每笔订单都撮合出当前最优交易。
进一步地，若所述采购方数量大于或等于预设阈值，则判定所述采购方数量满足集中采购的条件，根据集中采购方式进行交易撮合的步骤包括：
步骤S231，根据多个所述采购方的采购需求信息，将多个所述采购方采购商品的采购数量进行加和；
步骤S232，根据加和后的采购数量，向多个所述销售方发送招标信息；
步骤S233，根据多个所述销售方基于所述招标信息发送的投标信息，确定匹配度最高的销售方，完成对多个所述采购方与所述销售方的交易撮合。
进一步地，集中采购方式为：当采购方数量满足集中采购的条件时，集中采购平台根据多个采购方采购商品的采购数量信息以及采购价格信息，生成招标信息，并向多个销售方发送招标信息以进行竞标，通过以竞标的形式匹配销售方，得到采购商品的价格优惠，降低采购方的采购成本。进一步地，集中采购平台根据获取到的多个采购方的采购需求信息与多个销售方在销售方模块中记录的销售信息，将多个采购方的商品采购数量进行加和，并根据加和后的商品采购数量，向多个销售方发送招标信息，其中招标信息包括招标商品信息、招标数量信息、招标价格信息；集中采购平台获取多个销售方根据招标信息发送的投标信息，其中投标信息包括投标商品信息、投标数量信息、投标价格信息，自动筛选出匹配度最高即对应销售商品销售价格最优的销售方，并对多个采购方与销售方进行交易撮合，以使交易撮合过程中每笔订单都为当前最优交易，通过集中采购平台运用区块链技术的去中心化竞标，使得整个流程信息透明，降低了投标的信用成本，使得采购方与销售方在竞标过程中相互信任。
本实施例通过对不同数量的采购方采用不同的采购方式进行撮合，以及根据采购方不同的商品采购数量采用不同的撮合方式，保证交易撮合过程中每笔订单都可以撮合出当前最优交易，并通过由集中采购平台自动进行招标，简化了招标流程，实现更高效的采购管理以及招标信息的公开，避免采购腐败现象的出现，通过集中采购平台的交易撮合，保证交易撮合过程中每笔订单都可以撮合出当前最优交易，降低采购方的采购成本，同时通过去中心化竞标，使得整个流程信息透明，降低了投标的信用成本，使得买卖双方在竞标过程中可以互相信任。
进一步的，基于本申请基于区块链的集中采购方法第一实施例或第二实施例，提出本申请基于区块链的集中采购方法的第三实施例，在第三实施例中，向进行交易的所述采购方和所述销售方提供交易合同的步骤之后包括：
步骤S40，对由交易产生的交易订单进行进度信息监控，并将进度信息提供给所述采购方和所述销售方进行追溯。
进一步地，在采购方与销售方基于交易合同完成交易后，集中采购平台调用物流模块，对交易订单的进度进行监控，并将进度信息存储在集中采购平台上，以供进行交易的采购方和销售方进行查看及信息追溯，因为集中采购平台中区块链技术的去中心、匿名性和不可篡改的特点，使得集中采购平台存储的进度信息能够同步更新且不可篡改。
本实施例通过对交易产生的交易订单信息与物流信息进行监控与记录，由于集中采购平台由区块链技术构建，又因区块链技术具有不可篡改、可追溯、信息透明可信等特性，实现订单信息与物流信息的公开透明以及防止信息篡改，便于与交易相关的人员进行交易进度的查看与订单信息的追溯。
进一步地，本申请还提供一种基于区块链的集中采购装置。
