In addition, quality tracing files of each batch number formed by the generated electronic form can be recorded and stored through a block chain technology, and manual subsequent tampering is avoided.
By the control method of the output parameters of the printing semi-finished product in the printing workshop, the production process path, the feeding information and the output information of each process can be fed back, adjusted and controlled, and the parameters are automatically read and recorded in real time; read the number of meters produced from the control system of the printing machine, and combine the production operation management system, calculate the number of meters of each produced printing semi-finished product, carry out the automatic registration of production daily newspaper, replace the current manual record output, and automatically give printing production progress management, link such as traceing back management, need not the manpower to intervene completely, not only practice thrift a large amount of manpower statistics and report work, reduce the mistake that artificial intervention probably takes place, and production efficiency has also been improved, production progress management and control and quality management and control have been perfected.
That is, in a specific embodiment of the system to which the method for controlling output parameters of a printing semi-finished product in a printing shop according to the present invention is applied, the control system of the printing press is provided with the circumference of the printing plate rollers installed therein, so that each revolution is the length of the printing film in meters. When a roll of film starts to be printed, the control system of the printing machine can acquire the number of turns of the roller at any time, the number of turns is multiplied by the circumference of the roller, namely the number of the printed meters, and the data can be read in real time. After each roll of film is printed, the printer has an automatic cutting action, and the finished meter number of the roll of film is generated, and the data can be read in real time. After being read by the digital production process module, the set of data can be compared and analyzed with a production operation management system. In the production operation management system, the data of each piece of input raw material film under each production lot number, such as the initial length meter of the raw material film, can be accurately known, and each piece of film has a unique bar code. After the digital production process module submits the output meter number of the roll of film, the production operation management system can automatically check whether the output meter number is matched with the input meter number, the error is within an allowable range, namely the data is regarded as valid, the data is accepted as the output meter number and written into a production daily report. Meanwhile, the production operation management system can automatically write the data into a tracing record under the production batch number and write the data into the accumulated finished quantity of the printing process under the production batch number to form a progress report. When the output meters are not matched with the input meters, and the output meters are larger than the input meters, the production operation management system records the input meters and submits the input meters to a difference alarm report to remind people to make judgment; when the number of produced meters is smaller than the number of input meters, the production operation management system takes the number of produced meters as a standard to record, calculates the difference between the two meters as the waste product of the production batch number printing process, records the waste product into a waste product record table, and manually completes the filling of the cause information of the waste product to form a waste product analysis cause report for manual improvement and analysis.
