In some embodiments, the obtained type of agricultural product to be encoded is a specific type of agricultural product to be encoded. For example, at an apple planting base, the type of agricultural product to be encoded is obtained as "apple". Also, for example, in a vegetable planting base, the type of agricultural products to be encoded obtained is "radish" when radish picking is performed, and the type of agricultural products to be encoded obtained is "cabbage" when cabbage picking is performed.
In some embodiments, the agricultural product type encoding rule may include a rule for encoding a type of agricultural product recorded in a national publication or an industry standard, and after obtaining the type of agricultural product to be encoded, a commodity item code corresponding to the type of agricultural product to be encoded may be obtained according to the rule for encoding the type of agricultural product recorded in the national publication or the industry standard. For example, a 5-digit commodity item code corresponding to the type of agricultural product can be acquired using "agricultural product classification and code" issued by the agricultural division of the people's republic of China.
In some embodiments, the vendor coding rules may include rules for coding vendors recorded in national publications or industry standards, and after obtaining vendors of agricultural products to be coded, obtain vendor identification codes corresponding to the vendors of the agricultural products to be coded according to the rules for coding vendors recorded in national publications or industry standards.

In some embodiments, in step 330, the commodity item code and the vendor identification code may be combined arbitrarily to generate the commodity circulation code for the agricultural product, e.g., the commodity item code is spliced to the vendor identification code to generate the commodity circulation code for the agricultural product. For example, the commodity item code is inserted into the first three digits of the manufacturer identification code indicating the country, and then the commodity circulation code of the agricultural product is generated.
In some embodiments, the status of the agricultural product to be encoded obtained in step 130 is one of a production status, a warehouse status, a distribution status, a logistics status, or a terminal sales status.
In some embodiments, obtaining the status of the agricultural product to be encoded further comprises the steps of:

setting an agricultural product state coding rule, wherein the agricultural product state coding rule comprises a plurality of state codes, and each state code corresponds to the state of one agricultural product;
acquiring position information of agricultural products to be encoded;
judging whether the agricultural product to be encoded is in a production state or not according to the position information, if so, acquiring a state code corresponding to the production state as an agricultural product state code;
if not, the method comprises the steps of,
judging whether the agricultural product to be encoded is in a storage state according to the position information, if so, acquiring a state code corresponding to the storage state as an agricultural product state code;
if not, the method comprises the steps of,
judging whether the agricultural product to be encoded is in a distribution state according to the position information, if so, acquiring a state code corresponding to the distribution state as an agricultural product state code;
if not, the method comprises the steps of,
judging whether the agricultural product to be encoded is in a logistics state or not according to the position information, if so, acquiring a state code corresponding to the logistics state as an agricultural product state code;
if not, the method comprises the steps of,
judging whether the agricultural product to be coded is in a terminal sales state or not according to the position information, and if so, acquiring a state code corresponding to the terminal sales state as an agricultural product state code.
Specifically, the state of the agricultural product to be encoded is further subdivided into a production state, a storage state, a distribution state, a logistics state or a terminal sales state, whether the agricultural product to be encoded is located in the production state or the storage state or the distribution state or the logistics state or the terminal sales state is judged according to the position information of the agricultural product to be encoded, and the agricultural product state code corresponding to the state of the agricultural product to be encoded is merged into the agricultural product tracing code, so that the effect of accurately tracing the state of the agricultural product according to the agricultural product tracing code is realized.
In some embodiments, the agricultural product status encoding rules may include: the number 0 indicates that the agricultural product to be encoded is in a production state; numeral 1 indicates that the agricultural product to be encoded is in a warehouse state; numeral 2 indicates that the agricultural product to be encoded is in a distributed state; numeral 4 indicates that the agricultural product to be encoded is in a physical distribution state; numeral 5 indicates that the agricultural product to be encoded is in a terminal sales state.
As shown in fig. 4, the method further comprises the steps of:
step 410, obtaining the state of the agricultural product to be encoded, judging whether the state of the agricultural product to be encoded changes, if so, updating the state code of the agricultural product according to the current state of the agricultural product to be encoded;
and step 420, generating the agricultural product traceability codes corresponding to the agricultural products to be encoded according to the agricultural product space-time codes, the agricultural product commodity circulation codes and the updated agricultural product state codes.
For example, when the agricultural product to be encoded is transported from the stream position B to the terminal selling position a, the current position information of the agricultural product to be encoded is 47 degrees 48.362 minutes in east longitude, 30 degrees 90.715 minutes in north latitude, the position of the terminal selling position a is 47 degrees 48.36 minutes in east longitude, and 90.65 minutes in north latitude, it can be determined that the agricultural product to be encoded is located at the terminal selling position a, and the agricultural product to be encoded is in a terminal selling state, at this time, it can be judged that the agricultural product tracing code is updated, and the agricultural product state code in the updated agricultural product tracing code is changed from "4" representing the stream state to "5" representing the terminal selling state.
As shown in fig. 5, in some embodiments, the method further comprises the steps of:
step 510, generating a check code according to the space-time code of the agricultural product, the commodity circulation code of the agricultural product and the state code of the agricultural product;
and step 520, generating the agricultural product traceability codes corresponding to the agricultural products to be encoded according to the agricultural product space-time codes, the agricultural product commodity circulation codes, the agricultural product state codes and the check codes.
Specifically, the check code is a plurality of bits in the agricultural product tracing code, and is obtained by performing operation according to the agricultural product space-time code, the agricultural product commodity circulation code and the agricultural product state code, so as to check the correctness of a digital group formed by other numbers in the agricultural product tracing code.
In some embodiments, the agricultural product space-time code, the agricultural product commodity circulation code, the agricultural product status code, and the check code may be arbitrarily combined to generate the agricultural product traceability code. For example, referring to table 1, table 1 is used to show the agricultural product traceability code structure, splice the agricultural product commodity circulation code (vendor identification code, commodity item code) with the agricultural product space-time code (latitude coordinate code, longitude coordinate code, elevation coordinate code, picking time code), splice the agricultural product status code with the agricultural product commodity circulation code (vendor identification code, commodity item code), and place the check code at the last position to generate the agricultural product traceability code.
TABLE 1
In some embodiments, any feasible algorithm may be used in step 510 to generate the check code from the agricultural product space-time code, the agricultural product commodity circulation code, and the agricultural product status code, for example: and generating a check code according to the agricultural product space-time code, the agricultural product commodity circulation code and the agricultural product state code by using algorithms such as code distance, parity check, hamming check, cyclic redundancy check and the like.
In some embodiments, the method further comprises the step of:
and carrying out encryption calculation on the agricultural product traceability code to generate traceability anti-counterfeiting information.
For example, an AES128 encryption technique is used to encrypt the agricultural product traceability code to generate traceability anti-counterfeiting information. In the anti-counterfeiting verification process, AES128 decryption technology is used for decrypting and tracing anti-counterfeiting information and verifying the anti-counterfeiting information with the agricultural product tracing code, if the anti-counterfeiting information is different from the agricultural product tracing code, the agricultural product tracing code can be regarded as the false agricultural product tracing code, and therefore the security of the agricultural product tracing code is improved.
