Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an agricultural product tracing method based on edge calculation, as shown in fig. 1, the method includes: the bottom layer sensor collects agricultural product information data, agricultural product traceability data are generated, and the agricultural product traceability data are transmitted to the edge terminal. The agricultural product tracing data comprises a sensor id number, agricultural product information data and a mark code; the agricultural product information data comprises agricultural product planting, processing, warehousing, transportation and sale data. The edge terminal receives a plurality of agricultural product tracing data transmitted by a plurality of bottom sensors, stores the agricultural product tracing data, periodically packages and encrypts the agricultural product tracing data to generate first agricultural product data, and uploads the first agricultural product data to an edge server; the edge terminal receives first server data transmitted by an edge server, and if the first server data does not include the first agricultural product data, the first agricultural product data is uploaded to the edge server again. If the edge server does not have the first server data, the edge server receives the first agricultural product data, decrypts the first agricultural product data, generates first server data and sends the first server data to an edge terminal managed by the edge server; if server first data exists in the edge server, the edge server receives agricultural product first data, decrypts the agricultural product first data, combines the server first data and the agricultural product first data to generate new server first data, and sends the new server first data to an edge terminal governed by the edge server; the edge server periodically packages and encrypts the first server data to generate second server data, and uploads the second server data to the cloud platform; the method comprises the steps that an edge server receives first cloud data transmitted by a cloud platform, and if the first cloud data do not comprise the first server data, second server data are uploaded to the cloud platform again; if the cloud platform does not have the cloud first data, the cloud platform receives server second data, decrypts the server second data to generate cloud first data, and sends the cloud first data to an edge server governed by the cloud platform; if the cloud first data exists in the cloud platform, the cloud platform receives server second data, decrypts the server second data, combines the server second data and the server second data to generate new cloud first data, and sends the new cloud first data to an edge server governed by the cloud platform; the cloud platform periodically saves the cloud first data.
Specifically, agricultural product traceability data are generated by using agricultural product information data of a bottom sensor, and are transmitted to an edge terminal.
For example, most of the prior traceability consider the blockchain technology, but the blockchain technology has higher system computing requirements and storage requirements, and is not suitable for agricultural product traceability platforms under large data volume scenes. Therefore, the invention provides an edge computing framework, and computing and storing tasks are effectively shared by a multi-edge server. According to the agricultural product data updating method, data of different stages of agricultural products are written into a traceability system, basic data and stage transaction data are stored according to stages, the basic data of the agricultural products are uniformly stored by a cloud platform, and the basic data of the agricultural products need to be updated to the cloud platform every time the basic data of the agricultural products change. The tracing system comprises a bottom sensor, an edge terminal, an edge server and a cloud platform, wherein the edge terminal and the bottom sensor are in a one-to-many relationship; the edge server and the edge terminal are in one-to-many relationship; the cloud platform is arranged on the uppermost layer, and the cloud platform and the edge server are in one-to-many relationship. The agricultural product has a plurality of data from production to final sale, and the data is agricultural product information data, including agricultural product planting, processing, warehousing, transportation and sale data; for example, corn processing data can be generated during corn processing; transportation of rice from one location to another will generate transportation data. When the agricultural product information data is processed, the mark code is generated at the same time, the mark code has uniqueness, and the mark code corresponds to the agricultural product information data one by one. The mark code may only contain key data, and the main content of the agricultural product information data, such as "third batch of corn transaction", may be obtained through the key data, and it may be known through the mark code that the corresponding agricultural product information data is the third batch of corn transaction information, and the agricultural product information data includes specific information of the transaction, such as what time the transaction was made, which merchants made the transaction, and so on. The mark code may be designed in other ways as long as the function is realized. The invention uses the mark code and the agricultural product information data, the mark code realizes the basic data, and the agricultural product information data realizes the stage transaction data. The edge terminal stores the mark codes and the agricultural product information data, and the edge server and the cloud platform only store the mark codes, so that a large amount of data is effectively prevented from being stored on the edge server and the cloud platform.
Agricultural product information data is collected by different underlying sensors. Each hardware device has its own hardware id, and the hardware id has uniqueness, and the corresponding hardware can be found according to the hardware id. The bottom layer sensor collects agricultural product information data, the agricultural product information data is added with the sensor id and the mark code of the bottom layer sensor, agricultural product traceability data is generated, and the agricultural product traceability data is transmitted to the edge terminal.
Specifically, the edge terminal receives a plurality of agricultural product traceability data transmitted by a plurality of bottom sensors, stores the agricultural product traceability data, periodically packages and encrypts the agricultural product traceability data to generate first agricultural product data, and uploads the first agricultural product data to the edge server. The edge terminal packaging and encrypting the agricultural product traceability data comprises the following steps: the edge terminal processes the edge terminal id by using an RSA algorithm to generate a private key of the edge terminal and a public key of the edge terminal; the edge termination packing includes: generating an edge terminal packet header by using an edge terminal id, a current timestamp, a plurality of agricultural product traceability information data and a random number; the agricultural product traceability information data comprises a sensor id and a mark code; the edge terminal encrypting the agricultural product traceability data comprises encrypting the edge terminal packaging head by using an encryption algorithm, wherein a secret key is a private key of the edge terminal. The encryption algorithm is the SHA256 algorithm.
Illustratively, the edge terminals are close to the underlying sensors, collecting the underlying sensor data, and are able to save and make certain calculations. Each edge termination corresponds to a number of underlying sensors. And the edge terminal receives a plurality of agricultural product traceability data transmitted by a plurality of bottom sensors and stores the agricultural product traceability data. The method comprises the steps that an edge terminal processes an edge terminal id by using an RSA algorithm to generate a private key of the edge terminal and a public key of the edge terminal, the edge terminal generates an edge terminal packet header by using the edge terminal id, a current timestamp, a plurality of agricultural product traceability information data and a random number, and the agricultural product traceability information data comprise a sensor id and a mark code; if the packet header of the edge terminal a is "edge terminal idA + current timestamp + (sensor id1+ tag code 1) + (sensor id2+ tag code 2) + random number", and the packet header of the edge terminal B is "edge terminal idB + current timestamp + (sensor id3+ tag code 3) + (sensor id4+ tag code 4) + random number". The random number is automatically generated by the edge terminal. The edge terminal encrypts the edge terminal packaging head by using a SHA256(Secure HashAlgorithm) algorithm, wherein a secret key is a private key of the edge terminal. After the first data of the agricultural products are encrypted, the first data of the agricultural products are generated, and the edge terminal uploads the first data of the agricultural products to an edge server.
Specifically, if the edge server does not have server first data, the edge server receives agricultural product first data, decrypts the agricultural product first data, generates server first data, and sends the server first data to an edge terminal managed by the edge server; if server first data exists in the edge server, the edge server receives agricultural product first data, decrypts the agricultural product first data, combines the server first data and the agricultural product first data to generate new server first data, and sends the new server first data to an edge terminal governed by the edge server; and the edge server periodically packages and encrypts the first data of the server to generate second data of the server, and uploads the second data of the server to the cloud platform. The edge server processes the edge server id by using an RSA algorithm to generate a private key of the edge server and a public key of the edge server; the edge server packaging comprises: generating an edge server packet header by using an edge server id, a current timestamp, first data of a plurality of agricultural products and a random number; the edge server encrypting the server first data comprises encrypting the edge server packing header using an encryption algorithm, wherein a secret key is a private key of the edge server. The encryption algorithm is the SHA256 algorithm. The edge terminal receives first server data transmitted by an edge server, and if the first server data does not include the first agricultural product data, the first agricultural product data is uploaded to the edge server again.
Illustratively, the edge server is close to the edge terminal, and can collect and store data of the edge terminal and make certain limit calculation. The edge server and the edge terminal are in a one-to-many relationship. In the edge server, the server first data may or may not exist. If the first data of the server does not exist in the edge server, the edge server receives the first data of the agricultural product, the public key of the edge terminal corresponding to the first data of the agricultural product is used for decrypting the first data of the agricultural product, if the decryption is successful, the first data of the agricultural product is sent by the corresponding edge terminal, and if the decryption is unsuccessful, the first data of the agricultural product is discarded. And after the decryption is successful, generating first data of the server. For example, the edge server has no server first data, and after receiving the agricultural product first data sent by the edge terminal a, the generated server first data includes "edge terminal idA + current timestamp + (sensor id1+ tag code 1) + (sensor id2+ tag code 2)". In another design, the generated server first data includes "edge terminal idA + edge server current timestamp + edge terminal current timestamp + (sensor id1+ tag code 1) + (sensor id2+ tag code 2)", that is, the generated server first data includes the edge server current timestamp and also includes the edge terminal current timestamp in the edge terminal packet header. The following examples are all exemplified by only including the current hardware timestamp, and do not include the timestamp transmitted from the previous layer, and those skilled in the art can easily deduce the scheme including the timestamp transmitted from the previous layer. Since each server first data includes a time stamp, it is easy to find that a certain data is tampered with by comparing the last modification time of the data with the corresponding time stamp of the data in the different server first data.
If the first server data already exist in the edge server, after receiving the first agricultural product data, decrypting the first agricultural product data, combining the first server data and the first agricultural product data, and generating new first server data. For example, the edge server already has server first data, receives the first data of the agricultural product sent by the edge terminal B, decrypts and combines the server first data to generate new server first data, which includes "edge terminal idA + current timestamp + (sensor id1+ tag code 1) + (sensor id2+ tag code 2) + edge terminal idB + (sensor id3+ tag code 3) + (sensor id4+ tag code 4)". When the edge server generates the first server data or regenerates new first server data, the edge server sends the first server data to the edge terminal governed by the edge server.
The edge terminal receives first data of the server transmitted by the edge server, and if the first data of the agricultural products uploaded by the edge terminal is included in the first data of the server, the first data of the agricultural products uploaded by the edge terminal is added into the first data of the server. The edge terminal continuously receives a plurality of agricultural product tracing data transmitted by a plurality of bottom sensors, and regenerates new first agricultural product data which does not contain the previous first agricultural product data content. If the first data of the agricultural products uploaded by the edge terminal is not included in the first data of the server, the first data of the agricultural products uploaded by the edge terminal is not added into the first data of the server, and the edge terminal uploads the first data of the agricultural products again until the first data of the agricultural products uploaded by the edge terminal is included in the first data of the server. And the edge terminal continuously receives a plurality of agricultural product traceability data transmitted by a plurality of bottom sensors at the same time, regenerates the new agricultural product traceability data into new agricultural product first data and uploads the new agricultural product first data to the edge server according to the period. When the set uploading cycle time interval is larger, such as 1 hour, the phenomenon that the old first data of the agricultural products are not added into the first data of the server and the new first data of the agricultural products are uploaded can not occur.
After receiving the first data of the new agricultural product, the edge server adds corresponding content to the first data of the server, so that the first data of the server grows along with the increase of time. And the edge server periodically packages and encrypts the first data of the server to generate second data of the server, and uploads the second data of the server to the cloud platform. The edge server processes the edge server id by using an RSA algorithm to generate a private key of the edge server and a public key of the edge server; the edge server packaging comprises: generating an edge server packet header by using an edge server id, a current timestamp, first data of a plurality of agricultural products and a random number; the edge server encrypting the server first data comprises encrypting the edge server packing header using an encryption algorithm, wherein a secret key is a private key of the edge server. The encryption algorithm is the SHA256 algorithm. If the packet header of the edge server a is "edge server idA + current timestamp + edge terminal idA + (sensor id1+ tag code 1) + (sensor id2+ tag code 2) + edge terminal Bid + (sensor id3+ tag code 3) + (sensor id4+ tag code 4) + random number". And the edge server A encrypts the edge packing head by using SHA256, wherein the secret key is the private key of the edge server A. And after encryption is completed, generating second server data, and uploading the second server data to the cloud platform by the edge server A.
Specifically, if the cloud platform does not have the cloud first data, the cloud platform receives a server second data, decrypts the server second data, generates the cloud first data, and sends the cloud first data to an edge server governed by the cloud platform; if the cloud first data exists in the cloud platform, the cloud platform receives server second data, decrypts the server second data, combines the server second data and the server second data to generate new cloud first data, and sends the new cloud first data to an edge server governed by the cloud platform; the cloud platform periodically saves the cloud first data. The edge server receives first cloud data transmitted by the cloud platform, and if the first cloud data does not include the first server data, second server data is uploaded to the cloud platform again.
Illustratively, the cloud platform is close to the edge server, belongs to the uppermost layer, can collect and store data of the edge server, and can perform a large amount of computation. The cloud platform and the edge server are in a one-to-many relationship. In the cloud platform, cloud first data may or may not exist. If the cloud platform does not have the first cloud data, the cloud platform receives second server data, the public key of the edge server corresponding to the second server data is used for decrypting the second server data, if the decryption is successful, the second server data is sent for the corresponding edge server, and if the decryption is unsuccessful, the second server data is discarded. And after the decryption is successful, generating cloud first data. For example, after the cloud platform does not have cloud first data and receives server second data transmitted from the edge server a, the generated cloud first data includes "edge server idA + current timestamp + edge terminal idA + (sensor id1+ marker code 1) + (sensor id2+ marker code 2) + edge terminal idB + (sensor id3+ marker code 3) + (sensor id4+ marker code 4)". If the cloud first data already exists in the cloud platform, after receiving the server second data, decrypting the server second data, combining the cloud first data and the server second data, and generating new cloud first data. The method for generating the new cloud first data is the same as the method for generating the new server first data by the edge server, and a person skilled in the art can obtain how to generate the new cloud first data from the edge server generating the new server first data. After the cloud platform generates the first cloud data or regenerates new first cloud data, the cloud platform sends the first cloud data to all the edge servers.
The edge server receives first cloud data transmitted by the cloud platform, and if the first cloud data comprise second server data uploaded by the edge server, the second server data uploaded by the edge server are added into the first cloud data. The edge server continuously receives a plurality of agricultural product first data transmitted by a plurality of edge terminals, and regenerates new server second data, wherein the new server second data does not contain the previous agricultural product first data content.
And if the second server data uploaded by the edge server is not included in the first cloud data, the second server data uploaded by the edge server is not added into the first cloud data. The edge server uploads the second data of the original server again, and meanwhile receives the first data of the agricultural products transmitted by the edge terminal to generate new second data of the server.
When a user needs to trace the source of the agricultural product, the user can inquire at an edge terminal, an edge server or a cloud platform. The query method at the edge terminal is the same as that at the edge server, and the following description will be made by performing query at the edge terminal, from which a person skilled in the art can deduce the query method at the edge server. The user queries the data of agricultural product a at edge terminal a. If the relevant data of the agricultural product A is already stored in the edge terminal A, namely the first data of the server stored by the edge terminal A contains the relevant data of the agricultural product A, the edge terminal A directly returns the query result to the user. If the relevant data of the agricultural product A is not stored in the edge terminal A, namely the first data of the server stored by the edge terminal A does not contain the relevant data of the agricultural product A, namely the edge terminal A sends a query request to the corresponding edge server A, and the edge server A sends the query request to the cloud platform. The cloud platform queries the first cloud data stored by the cloud platform. The cloud platform stores basic data, if the cloud first data do not contain related data of agricultural products A, the fact that the agricultural products A do not exist in the whole platform is represented, and the cloud platform sends no information to a client through an edge server A-an edge terminal A; if the cloud first data contain relevant data of the agricultural product A, assuming that the agricultural product data are stored in an edge terminal B under an edge server B, the cloud platform sends a query request to the edge terminal B through the edge server B, the edge terminal B transmits the agricultural product information data to the cloud platform, and the cloud platform sends corresponding information to a client through the edge server A and the edge terminal A. The cloud platform can also directly reply the data of the edge terminal A to the edge terminal B, and the edge terminal A directly queries the edge terminal B. If the user inquires on the cloud platform, the cloud platform inquires in the first cloud data stored in the cloud platform, and if the first cloud data does not contain related data of the agricultural product A, the agricultural product A information does not exist in the cloud platform, and the cloud platform replies to the client that the information does not exist; and if the cloud first data contain the relevant data of the agricultural product A, the cloud platform sends a request to the corresponding edge terminal, and the cloud platform replies corresponding information to the client after obtaining the specific data.
