Detailed Description
The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.
In order to more clearly understand the technical solution in the present application, first, a usage scenario is briefly introduced, taking a production process of a product as an example, in the production process of the product, an identification code is attached to the product, the identification code includes the whole production process information, and the identification code sequentially passes through each process as the product flows on a production line.
In each process, a camera is equipped to collect images and/or videos, and after the collection is completed, the images and/or videos are stored based on the identification codes, that is, at each process, the images and/or videos are generated by using the identification codes as indexes.
After production is finished, for a group of products, images and/or videos are left at each process, and at the moment, the images and/or videos need to be collected according to identification codes for packaging and storage, so that a user can conveniently check the images and/or videos.
According to the technical scheme, the execution main body is a terminal, the terminal is installed at the tail end of a production line and mainly comprises a camera, a host and a communicator, the camera is responsible for shooting pictures, the host is responsible for processing data, and the communicator is responsible for data interaction of other terminals (such as a camera, a PLC or a DCS and the like) on the production line.
Referring to fig. 1 and fig. 2, a tracing information generating method based on a block chain disclosed in an embodiment of the present application includes the following steps:
s101, in response to the acquired finishing instruction information, acquiring image information at a first position;
s102, analyzing the image information and determining that the image information contains first identification information;
s103, acquiring identity identification information in the first identification information;
s104, obtaining traceability information from other acquisition terminals according to the obtained identity identification information, wherein the traceability information comprises character information, picture information and image information, and the traceability information takes the identity identification information as an index;
s105, packaging the identity identification information and the source tracing information, and sending the packaged identity identification information and source tracing information to a storage server;
s106, generating corresponding two-dimensional code information according to the identity identification information; and
and S107, sending the two-dimension code information to the terminal equipment at the first position.
Specifically, in step S101, the terminal performs data communication with the production line, and receives completion instruction information given by the production line, where the completion instruction information is used to inform the terminal that the product has completed the whole production process and needs to start the collection of the traceability information.
For the terminal, after obtaining the completion instruction information sent by the production line, a photo is taken, that is, image information at a first position is obtained in step S101, where the first position is the end position of the production line, and the obtained image information is used for providing the reference data information for the subsequent steps.
It should be understood that, for the terminal shown in the embodiment of the present application, it is additionally installed on the production line, so that the production line cannot be modified on a large scale, and only the terminal can be installed by adopting an additional installation method, so that the analysis after image acquisition by using the camera is more suitable for the actual requirements of the scene.
It should also be understood that for the cameras to be added later, the local storage is more suitable, because the corresponding network memory is not specially equipped, and the local storage of the cameras only needs to be accessed during data retrieval to meet the use requirement.
In step S102, the terminal analyzes the image information, and determines that the image information includes first identification information, where the first identification information is a special identification mark on the commodity, such as a bar code, a two-dimensional code, or a number with a certain meaning, and the first identification information can determine that the product has completed the whole production process, and trace back forward to obtain the required picture and/or image information.
If the image information does not contain the first identification information, the image information at the first position needs to be acquired again, and it should be understood that in the process of shooting the image information, situations such as wrong shooting opportunity, blurred image, inappropriate brightness and the like may occur, the first identification information may not be identified, and shooting needs to be performed again at this moment.
For the conditions of image blurring, inappropriate brightness and the like, the camera can be controlled to carry out correction in various modes such as adjusting the focal length, adjusting the exposure time or turning on a light supplement lamp.
After determining that the image information includes the first identification information, step S103 is executed, in which the first identification information is processed to obtain the identification information included therein.
For example, the first identification information is a two-dimensional code, and at this time, the two-dimensional code cannot be directly used, and needs to be read to obtain the identification information included therein, and then, images and/or videos at other positions on the production line are traced according to the identification information.
And step S104 is executed, in the step, the terminal acquires the traceability information from other acquisition terminals according to the acquired identification information, and because the identification information is unique, the traceability information related to the identification information on the whole production line can be traced, and the production process can be uniformly managed.
For example, other acquisition terminals at other positions on the production line can also recognize the first identification information in the working process, so that in the data acquisition process, the identification information can be used as a stored identifier to store the acquired data, and then in the subsequent process of calling the data, the folders or the storage contents with corresponding names can be directly searched.
For the traceability information, there are several types,
first, the text information can include time, position, temperature and humidity, etc. and production related data;
secondly, the picture information can be pictures shot in the production process;
thirdly, the image information can be a video recorded in the production process;
the tracing information has the function of enabling a user to know the production process more intuitively, so that the trust degree of the product is improved.
After the search is completed, step S105 is executed, in which the identification information and the obtained traceability information are packaged and sent to a storage server for storage, where the storage server may directly send the data to a terminal where the user is located when the user needs to obtain the data.
It should be understood that before collection, the data are stored in a scattered manner on each terminal, and from the perspective of a user, the data are viewed relatively unchanged, and problems such as loss, interruption, and jamming may also occur.
In step S106, corresponding two-dimensional code information is generated according to the identification information, the two-dimensional code information is to be attached to the product and is provided for the user to use, and when the user needs to check the traceability information, the user can directly scan the two-dimensional code on the product to check the corresponding traceability information.
It should be understood that in the tracing process, the collected tracing information is indexed by the identification information, and then the two-dimensional code is generated by using the identification information as a basis, so that the two-dimensional code can be directly associated with the collected tracing information.
And finally, step S107 is executed, in which the two-dimensional code information is sent to the terminal device at the first position, where the first position is the position mentioned in step S101, and when the article reaches the first position, the whole production process is completed, and after the terminal takes a picture, the terminal collects information at other positions on the production line according to the first identification information in the picture, and also generates a piece of two-dimensional code information according to the first identification information.
The two-dimension code information is simultaneously sent to the terminal equipment at the first position, printed by the terminal equipment and pasted on the surface of a product. Therefore, after a user purchases a product, the user can acquire the text information, the picture information and the image information related to the product in the production process in a mode of scanning the two-dimensional code.
On the whole, the traceability information generation method based on the block chain shown in the embodiment of the application obtains the first identity identification information on the product by taking a picture, then performs traceability information collection on a production line through the first identity identification information, simultaneously generates the two-dimensional code for being provided for a user to scan, and sends the two-dimensional code to the corresponding terminal device to print and then paste the two-dimensional code on the product.
The mode can collect information by taking the product as the final guide, and is convenient for the user to view.
As a specific implementation of the block chain-based tracing information generation method provided by the application, for the first identification information, a plurality of pieces of location information are added in the first identification information as supplements, and in the subsequent tracing process, tracing information can be obtained from other acquisition terminals corresponding to the location information according to the location information, without visiting each terminal, and whether there is tracing information that needs to be collected.
Taking a specific use scenario as an example, various commodities are produced in a hybrid manner by using a flexible production line, different production processes may be involved for different products, and if position information is added in first identification information as a supplement, the traceability information can be collected according to the position information for the first identification information acquired by the terminal without visiting each device on the production line, so that the workload of collecting the traceability information can be effectively reduced, and the working efficiency can be improved.
Furthermore, the first identification information also comprises second identification information corresponding to the position information, and the second identification information is used as a name of the traceability information, so that the traceability information can be directly obtained in a retrieval mode in the process that the terminal accesses other acquisition terminals, the acquisition speed is higher, and the efficiency is higher.
It should be understood that storage is performed at the same position, the same file name needs to be modified, and after the second identification information is added, the name during storage is directly specified, so that storage can be directly performed in the storage process, the step of modifying the name is avoided, on one hand, operation steps during storage are reduced, and on the other hand, errors which may occur in modifying the name are also reduced, for example, problems that the actual stored name is inconsistent with the required name and cannot be retrieved after the name is modified are solved.
On the whole, after the position information and the second identification information are added, the tracing information is more convenient to search and collect.
As a specific implementation of the traceability information generation method based on the block chain, for the collection of information, the following steps are added:
s201, acquiring production information according to the identity identification information, wherein the production information comes from a production information database; and
s202, packaging the identity identification information, the production information and the source tracing information, and sending the packaged identity identification information, production information and source tracing information to a storage server;
wherein the production information comprises name information, place of production information and shelf life information.
Specifically, in step S201, the production information is obtained according to the identification information, the production information is derived from the production information database, and the purpose of this step is to further enrich the content of the traceability information, specifically, the identification information is used to query the production information database, and then the queried production information and identification information are packaged with the traceability information and then sent to the storage server for storage, that is, the content in step S202.
It should be understood that, for a product, besides the traceability information involved in the processing process, there are production information before processing (name information, production place information, shelf life information, etc.), and these information can also be sent to the storage server for storage, so that after the user scans the two-dimensional code, the user can obtain more comprehensive information, and at the same time, the user can compare with the information printed on the product to check whether the two information are consistent.
