Module, wherein：Data collecting module collected soil information and agricultural product kind of information, and be transferred in the form of structural data
Block information builds module；It is that agricultural product distribute identity label that block information, which builds module, by the structural data structure received
Build up Merkle trees and be digitally signed with time-stamping service to be formed the block after block information, the amount of being operated proof
Information is propagated by p2p；Storage sharing module should after checking the block information amount of the being operated checking received and data
Block information is broadcasted；Assessment module carries out performance rating to agricultural product according to block information and obtains mass fraction；Enquiry module connects
Receive block information and mass fraction generation inquiry Quick Response Code.
Described data acquisition module includes：Data pre-processing unit and data structured unit, wherein：Data prediction
Unit soil information and agricultural product kind of information are pre-processed and after through data structured unit generating structure data.
Described preprocessing process includes：The abnormal data during collecting is rejected, such as negative is anxious in collection period
The numerical value that play declines；Accuracy value to all kinds of gathered datas is unified；Processing to default value, is defaulted as the number in a cycle
The data deduced according to or according to historical data rule.
Described soil information includes the nutritive element content and contents of heavy metal elements of soil.
Described storage sharing module is proved by the Hash256 algorithm amounts of being operated.
Described assessment module includes：Computing unit and authentication unit, wherein：Authentication unit verifies the identity mark of agricultural product
After label, computing unit extracts the corresponding block information of agricultural product and calculates mass fraction V(t)。
Described mass fraction

Member receives block information and mass fraction generation Quick Response Code corresponding with agricultural product, and information query unit is to two-dimensional code scanning
Person provides the mass fraction and agricultural product kind of information of the agricultural product.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
As shown in figure 1, the present embodiment includes：Data acquisition module, block information build module, storage sharing module, commented
Cover half block and enquiry module, wherein：Data collecting module collected soil information and agricultural product kind of information, and with structural data
Form be transferred to block information build module；It is that agricultural product distribute identity label that block information, which builds module, by what is received
Structural data is built into Merkle trees and is digitally signed with time-stamping service to form block information, the amount of being operated card
The block information is propagated by p2p after bright；Storage sharing module verifies sum to the block information amount of being operated received
According to the block information is broadcast into other block informations after inspection；Assessment module carries out quality to agricultural product according to block information and commented
Surely mass fraction is obtained；Enquiry module receives block information and mass fraction generation inquiry Quick Response Code.
Described data acquisition module includes：Data pre-processing unit and data structured unit, wherein：Data prediction
Unit soil information and agricultural product kind of information are pre-processed and after through data structured unit generating structure data.Soil
The nutrient in soil constituent detector and heavy metal-polluted soil detector, soil constituent detector detection soil is set to contain in earth
Contents of heavy metal elements in amount, heavy metal-polluted soil detector detection soil.Nutritive element content and contents of heavy metal elements
Constitute soil information.
Described block information is built module and gone out according to the identity information and agricultural product batch of farmer using public key Hash
The identity label of agricultural product, is used as the unique mark of the agricultural product of the batch.By the structuring number collected in certain period of time
According to structure Merkle trees, memory space is saved so as to only retain root node information, to build block information.Then circulation is guessed
One value of survey and the information one that oneself has are reinstated the Hash256 algorithm amounts of being operated and proved, if preceding n of the character string calculated
It is consistent that zero number and system are set, then it is assumed that proof of work success, then passes the block information to other node p2p
Broadcast.
Described storage sharing module is received after block information, its amount of being operated is verified, that is, the character string obtained
The numbers of preceding n positions zero whether meet zero digit of default, then the data in block information are checked, for example
Data whether repeat etc., if check pass through, the block information is connected under corresponding block, to form block chain.Such as
Fruit is wanted to change the block information of some block, then needs to recalculate the proof of work work of all blocks, when some area
When the latter linked number of blocks of block reaches some value, recalculating all working amount of the block and its rear block proves, is several
It is impossible, so as to ensure that the data in block can not be tampered.The block is received to neighbor node broadcast simultaneously
Block information, so as to update the information of whole block chain, the nodes for keeping the information of all nodes basically identical and all
Safeguarded according to by collective, embody the disclosure and fairness of system.
