In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
Referring to fig. 1, an embodiment of the present invention provides a block chain-based method for credibly counting total live pigs, including the following steps:
s1, uploading the image photos of the anti-counterfeiting two-dimensional codes to a blockchain server, and establishing unique codes for the anti-counterfeiting two-dimensional codes;
s2, the initial user sends an application request to the blockchain server, the blockchain server issues an account and a login password to the initial user, and issues the corresponding anti-fake two-dimensional code to the initial user to carry out one-to-one listing on live pigs;
s3, the initial user uses a code scanner with a GPS function to read the anti-counterfeiting two-dimensional code regularly so as to access the block chain server, and the block chain server requests login information and GPS information from the code scanner;
s4, the block chain server acquires the login information and the GPS information and then stores the GPS information and the write-in information of the initial user into the block chain server;
and S5, the block chain server further updates the total amount and the tradable state of the live pigs according to the written information of the user, wherein the total amount and the tradable state are updated on the block chain server in a chart form at regular time or an additional block chain is established and updated on the block chain server.
In step S1, referring to fig. 2, the anti-counterfeit two-dimensional code includes a printing layer (10), an anti-counterfeit ink (11) printed on the surface of the printing layer (10), and a protective layer (12) covering the surface of the anti-counterfeit ink (11), wherein the periphery of the image-seeking pattern of the anti-counterfeit ink (11) has micron-sized random anti-counterfeit ripples (111). The height of the micron-sized random anti-counterfeiting corrugation (111) is 100-500 microns, and the distance is 3-8 mm. The micron-sized random anti-counterfeiting corrugation (111) can be obtained by processing the periphery of the image-searching pattern of the anti-counterfeiting ink (11) through ultrasonic waves in the curing process of the anti-counterfeiting ink (11).
Specifically, the method comprises the following steps:
s11, adopting a jet printing machine to jet print random ultraviolet light curing ink codes on the printing layer (10);
s12, processing the periphery of the figure-seeking pattern of the ultraviolet light curing ink code by using ultrasonic waves, and enabling the periphery of the figure-seeking pattern of the ultraviolet light curing ink code to generate micron-scale random anti-counterfeiting ripples (111);
s13, curing the ultraviolet curing ink codes by using ultraviolet rays;
and S14, finally, covering a transparent protective layer (12) on the ultraviolet light curing ink codes.
As a further improvement, a label can be further attached to the protective layer (12) to prevent the two-dimensional code from being disordered.
The reason that the periphery of the image searching pattern coded by the ultraviolet light curing ink is only treated by ultrasonic waves is that the image searching pattern is generally large in size, and micron-sized random anti-counterfeiting ripples (111) are formed on the periphery of the image searching pattern, so that the use of the image searching pattern cannot be influenced. In addition, the processing range and the processing area of the ultrasonic wave are relatively controllable. In one embodiment, only one of the viewfinder graphic perimeters is treated with ultrasound. The frequency of the ultrasonic wave is not limited, and in another embodiment, the frequency of the ultrasonic wave is 40 KHz. It can be understood that the random anti-counterfeiting ripples (111) with the interval of micron order can be obtained through the control of the frequency of the ultrasonic wave, and the interval of the random anti-counterfeiting ripples (111) of micron order is positively correlated with the frequency of the ultrasonic wave. In order to obtain the random anti-counterfeiting ripples (111) with the interval of micron order, preferably, the frequency of the ultrasonic wave is 30 KHz-50 KHz.
And after the anti-counterfeiting two-dimensional code is prepared, further acquiring an image photo of the anti-counterfeiting two-dimensional code through a high-definition camera, uploading the image photo to a block chain server, and establishing a unique code for each anti-counterfeiting two-dimensional code.
When the two-dimensional code is copied, because the micron-sized random anti-counterfeiting ripple (111) at the periphery of the image-searching graph cannot be copied by the existing printer or copying equipment, the image of the anti-counterfeiting two-dimensional code stored in the block chain can be called for comparison, and the method specifically comprises the following steps:
and acquiring a simulated two-dimensional code image by using a high-definition camera, and comparing the simulated two-dimensional code image with the anti-counterfeiting two-dimensional code image stored in the block chain server, so as to identify the authenticity of the two-dimensional code.
In step S2, the initial user may make an application request to the blockchain server, and the blockchain server issues an account and a login password to the initial user. The application request comprises information (name, address, contact information and the like) of an initial user, the number of the applied anti-counterfeiting two-dimensional codes and the like. And the block chain server issues the number of the anti-counterfeiting two-dimensional codes of the corresponding number in the block chain to the account according to the number of the applied anti-counterfeiting two-dimensional codes, and distributes the physical anti-counterfeiting two-dimensional codes to the hands of the initial user. The initial user can carry out one-to-one listing on the live pigs after receiving the physical anti-counterfeiting two-dimensional code.
In step S3, the initial user can use a scanner with GPS function to periodically read the anti-counterfeit two-dimensional code to access the block chain server during the raising process. And the initial user logs in through the account and the login password, and at the moment, the block chain corresponding to the code scanning sends a request for requesting the GPS information to the code scanner. It is possible that in this process, the initial user must default to the state in which the GPS information of his own scanner is accessible. The code scanner may be a mobile phone or other intelligent device, etc. When the anti-counterfeiting two-dimensional code is in a login state, different anti-counterfeiting two-dimensional codes can be continuously scanned, and therefore position information of different anti-counterfeiting two-dimensional codes can be updated.
In other embodiments, step S3 may be equivalently replaced with step S3'.
S3', the initial user logs in the block chain server by using a code scanner with a GPS function, then the anti-counterfeiting two-dimensional code is read by using the code scanner at regular time, and the block chain server requests GPS information from the code scanner.
In step S4, the written information includes pig type, growth condition, and tradable status. The written information can also comprise information such as total amount, output amount, stock amount, death amount, water consumption, feed intake, immunity amount, veterinary drug amount and the like.
In other embodiments, the step S4 may further include:
and S41, the block chain server converts the GPS information into geographical position information, and then stores the geographical position information into the block chain server.
In step S5, the total amount and tradable status may be updated on the blockchain server periodically in a graph form, or may be updated on the blockchain server in a production form of an additional blockchain. In one embodiment, an additional global and tradable state blockchain is established on the blockchain server, and data updates on the server are written to the blockchain at regular times.
As a further improvement, the step S5 further includes:
and S51, the block chain server further constructs a visual map, and updates the position information and the tradable state of the live pig on the visual map according to the geographical position information.
Specifically, generally, the application of the initial user is applied in a farm unit, and therefore the blockchain server can count the cultivation number, variety and tradable state of different initial users and update the cultivation number, variety and tradable state on the visual map in real time, so that the client can conveniently trade.
In step S5, when livestock are traded, the initial user may set the blockchain of the corresponding livestock to a scannable code written state. The state of writing the scannable code is relative to the state that the initial user needs an account number and a password to write the code, and the state of writing the scannable code does not need an account. And only the purchaser needs to access the block chain server by reading the anti-counterfeiting two-dimensional code through a second code scanner with a GPS function, and the block chain server requests GPS information from the second code scanner and writes the GPS information into the corresponding block chain. Because the livestock is in the circulation process, the purchaser generally scans the two-dimensional code of the livestock to obtain the actual information of the livestock, and therefore tracking of the livestock in the cultivation and circulation process can be finally achieved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
