The mobile phone numbers bound by the WeChat are directly associated, so that the user can modify the mobile phone numbers into account numbers corresponding to the platform user while authorizing to obtain the mobile phone numbers, and the purpose of associating accounts is achieved.
And the WeChat small program code scanning and source tracing inquiry is used for a consumer to check the complete circulation link information of the commodity. Through a WeChat scanning or a tracing two-dimensional code generated by scanning enterprise application system tracing account book management or WeChat applet code scanning tracing function, all commodity circulation link information of the commodity and basic tracing information of the account book can be directly inquired, wherein the tracing information comprises tracing times, tracing scoring, tracing commodity information and tracing marking information. The consumer can grade and label the source tracing at this time through the quality labeling function of the invention, and directly transmit the data to the operation platform and the block chain platform.
And the WeChat applet traceability link, the associated code assigning and the printing code assigning functions are consistent with the corresponding functions of the enterprise application system. And the WeChat applet associated code center has the same code assigning management function with the enterprise application system.
Further, the panoramic display module 103 in the operation platform 10 is used for account book management of an enterprise application system, code scanning and source tracing inquiry of a wechat applet and visual icon display of a consumer new situation, and main data of the panoramic display module is derived from a public enterprise application system 202;
further, based on the first embodiment of the commodity traceability system based on the block chain, a second embodiment of the commodity traceability system based on the block chain is provided;
in a second embodiment of the commodity traceability system based on the blockchain, the method includes:
when the printing code assigning operation is executed, different printing choices are provided for adapting to the business scene modes of different enterprises or individual merchants, so that the code assigning rate is improved;
in the embodiment, the method comprises the steps that the WeChat applet interacts with the printer and the enterprise application system interacts with the printer;
specifically, the WeChat applet interacts with the printer and is used for printing the code and the source tracing two-dimensional code by the associated code center. The WeChat applet in the embodiment transmits the printing data to a printing interface of the portable printer, searches and connects with the Bluetooth printing equipment through the Bluetooth API, self-checks the state of the Bluetooth printing equipment, and if the state of the Bluetooth printing equipment is normal, the WeChat applet sends the tracing two-dimensional code information to the Bluetooth printing equipment, and the Bluetooth printing equipment executes a printing task after receiving the tracing two-dimensional code;
and the printer interaction of the enterprise application system is used for assigning codes of the enterprise application system, managing and printing the assigning codes and printing the tracing two-dimensional codes. The enterprise application system firstly checks whether the printing drive is normally started or not, and if the printing drive is normally started, the source tracing two-dimensional code is firstly generated and connected with the printing drive. The connection is successful, the printing data of the tracing two-dimensional code is transmitted to the printing driver, and the printing driver calls the default printer connected with the current PC after receiving the tracing two-dimensional code data to finish the printing of the tracing two-dimensional code.
