Design And Research Of Embedded Printer System With Remote Web Control

With the rapid development of the global economy,the endless styles of goods,more and more types,a variety of complex styles of commodity packaging.In order to make the product easy to trace,to ensure product quality,the product packaging is particularly critical for the printing code mark.At present,the domestic market is used in industrial production of more printing machine equipment still uses traditional single-chip computer for control,with a single control interface function,control mode requires manual intervention and other defects.In addition,this type of printer can not achieve remote control management,resulting in each printer needs to be equipped with operators for on-site control management,increasing the cost of human supervision,can not better meet the needs of the development of industrial intelligence.In response to the above problems,this paper is based on the intelligent development needs of the modern industrial printing market,research on the domestic and foreign coding machine control functions and system performance,and its control system technology research status,through the continuous inkjet coding machine after in-depth analysis of the working principle,around the coding machine control management function,the coding machine control nozzle part of the hardware circuit design,part of the software algorithm to improve and Optimization.This paper designs a remote Web control system for a continuous inkjet small character printer based on instant communication technology on the Web side to meet the functional requirements of the remote control management system of the printer.The research work in this paper consists of the following three parts:(1)The design of the hardware module of the continuous inkjet small character inkjet printer.The Samsung 4412 processor with STM32 processor is used to replace the traditional microcontroller system with a dual processor,and part of the hardware schematic design is carried out.It includes power supply circuit,ink drop charging circuit,ink drop phase detection circuit and high voltage generation circuit.(2)Design and software programming of remote Web control system.Based on the Webbased instant communication technology,the Web server Apache HTTP Server for embedded printer system was built,and the server was ported and configured;the CGI(Common Gateway Interface)program for controlling the printer was developed for data transmission between the Web server and the application.The CGI(Common Gateway Interface)program to control the printer was developed for data transmission between the Web server and the application;the Web web page control system and the corresponding graphical interface were designed and developed based on the Java Script language,relying on the Vue architecture and the Element UI component,including functions such as creating and adding local files.(3)Improvement of character printing algorithm and phase detection algorithm.Improved the printer character printing algorithm and phase detection algorithm,in the phase detection process using the technology of quantization processing,by matching the printer hardware system for printing ink droplets charged amount detection,when the ink droplet temperature and quality,such as different,phase detection algorithm with phase detection circuit to calculate the best printing voltage,you can determine the best printing moment.
