and if the product information characteristic parameter K belongs to the data interval in the sorting data set, the traceability module judges that the information characteristic parameter K is matched with the sorting data set, calls the sorting data set, and performs access traceability on the nodes in the blockchain network according to the sorting sequence and the access time interval of the nodes in each node cluster in the matched sorting data set.
5. The blockchain-based multi-source spatial data industrial chain tracing system according to claim 4, wherein the tracing module determines an industrial chain step to which industrial chain information belongs according to the tracing requirement information, and accesses nodes in a node cluster associated with the industrial chain step first.
6. The multi-source spatial data industrial chain tracing system based on block chain of claim 5, wherein each node of said block chain network is provided with a verification unit, said verification unit receives an access request and verifies a tracing module that issued said access request,

when the identity verification is not passed, the verification unit prohibits the traceability module from accessing the node,
when the identity verification is passed, the verification unit starts to judge whether the previous node accessed in the single tracing process of the product industrial chain information by the tracing module and the current access node belong to the same node cluster,
if the previous node accessed by the tracing module and the current node do not belong to the same node cluster, the verification unit determines the node cluster corresponding to the previous node accessed by the tracing module, calls access records of all nodes in the node cluster, acquires the access records, determines the actual access sequence and the actual access time interval of the tracing module to all the nodes, verifies whether the actual access sequence and the actual access time interval are correct, and when the actual access sequence and the actual access time interval are correct, the verification unit determines that the verification is passed and allows the tracing module to access;
and if the previous node accessed by the traceability module and the current access node belong to the same node cluster, the verification unit judges that the verification is passed and allows the traceability module to access.

and compares the access order and access time interval with the actual access order and actual access time interval,
if the actual access order is the same as the ordering order, determining that the actual access order is correct,
and if the actual access time interval is the same as the access time interval, judging that the actual access time interval is correct.
8. The multi-source spatial data industrial chain tracing system based on block chain according to claim 6, wherein the verification unit determines whether the access of the tracing module to the node belongs to a single tracing process, a preset minimum time interval is set in the verification unit, when the tracing module traces the industrial chain information of any product, the verification unit determines whether the access time interval of the tracing module to the current node and the previous node is smaller than the preset minimum time interval,
and if the access time interval is smaller than the preset minimum time interval, the verification unit judges that the access of the tracing module to the current node belongs to a single tracing process of the product.
9. The multi-source spatial data industrial chain tracing system based on block chain according to claim 8, wherein said verification unit obtains records of all nodes which said tracing module is allowed to access in a single tracing process from each node, and determines the number N0 of nodes which store the corresponding industrial chain information of the product to be traced in all nodes,
if the number of node clusters corresponding to the allowed access nodes exceeds the preset comparison number N in the single tracing process, the verification unit compares N0 with the preset verification comparison parameter M to determine whether to adjust the verification mode of the tracing module, wherein N is greater than or equal to 2,
when N0 is more than or equal to M, the verification unit judges that the verification mode of the traceability module is adjusted, and when the verification unit verifies the access request of the traceability module in the current traceability process, only identity verification is performed;
and when N0 is less than M, the verification unit verifies the traceability module in an original mode.
10. The blockchain-based multi-source spatial data industrial chain tracing system according to claim 1, wherein a marking node cluster is further arranged in the blockchain network, the marking node cluster comprises a plurality of marked nodes, the marked nodes are used for storing production characteristic data of each product, the production characteristic data comprise production time of the product and the number of times of uploading the industrial chain data generated by each industrial chain step of the product to the blockchain network, and a verification unit in the marked nodes only verifies the identity of the tracing module.
