4. The adaptive high-speed coding method according to claim 1, wherein the step S40 further comprises: and the coding terminal calculates coding speed, production line speed and current coding content according to the printing completion information returned by the printer.
5. The self-adaptive high-speed coding system is characterized by comprising a configuration module, a coding terminal, a printer, a cigarette case detection device and a coding quality detection device, wherein,
the configuration module is used for generating a coding rule according to information input by a user, and switching a printing file of the printer according to the coding rule, wherein the printing file comprises printing content, a traceability code printing position and size, printing power and a triggering mode; different contents and coding requirements on the traceability codes are provided for different export countries and regions; meanwhile, different manufacturers have different requirements on the readability of the traceability code; selecting code printing rules, selecting manufacturer requirements, forming configuration combinations for code printing requirements, and synchronously issuing the configuration combinations and the traceability codes to a print job;
the code printing terminal is used for reading a preset number of trace codes from the trace code cache queue, generating a plurality of code printing information according to the code printing rule, sending the code printing information to the printer, and storing the code printing information in the local print cache queue of the printer;
the cigarette case detection device is used for detecting whether cigarette cases move on a production line, generating a coding trigger signal corresponding to the moving speed of the cigarette case when detecting that the cigarette cases move, and sending the coding trigger signal to the printer;
the printer is used for receiving the coding information sent by the coding terminal and storing the coding information into a local printing cache queue of the printer, taking out the coding information in the local printing cache queue according to the coding trigger signal sent by the cigarette case detection device, coding in sequence according to the trigger mode, and synchronously returning the printing completion information to the coding terminal after coding is completed;
the coding quality detection device comprises a code reader and a rejecting device, wherein,
the code reader is used for identifying and analyzing the coding quality of each cigarette case; and when the traceability code on the cigarette case is successfully identified, analyzing the identified traceability code to obtain the printing position and the printing content, judging whether the printing position and the printing content are correct, and
when the printing position is incorrect, notifying the coding terminal to adjust coding information;
when the printing content is incorrect, rejecting the cigarette case by the rejecting device, and when the rejecting quantity reaches a specified threshold value in a specified time interval, alarming and sending a stop signal to a production line;
the identifying and analyzing includes:
identification of the code: the code reader directly identifies the content of the two-dimensional code, and if the identification is successful, the identified character string content is sent to the code printing terminal program; if the identification fails, an ERROR label of ERROR is sent;
processing codes: the code printing terminal program analyzes whether the content of the received two-dimensional code accords with the rule of the current task, and if not, the code printing terminal program needs to give an alarm and send a stop signal to the production line;
processing pictures: the code printing terminal program can check the pictures acquired by the code reader, and can analyze whether the whole graph is distorted or not through a graph algorithm, and the offset is left and right and the offset is up and down; the offset of the code printing left and right and up and down can be obtained through processing the pictures acquired by the code reader, and the code printing terminal program can be adjusted by adjusting the position of the code in the printed file;
the removing device is used for removing the cigarette case and notifying the coding terminal when the tracing code on the cigarette case cannot be identified by the code reader, and alarming and sending a stop signal to the production line when the removing quantity reaches a specified threshold value within a specified time interval.
