【摘要】：当今喷码打印技术呈现出高速、低维修率、人性化操作方式及智能化的趋势，而在国内，喷码机技术相对于国外还存在巨大差距，无法较好地满足生产流水线的需求和现阶段的社会需求。针对以上问题，本文将在原有硬件设计基础上，研究并实现一套基于嵌入式系统的生产线喷码打印机的控制方法。首先，本文介绍了国内外喷码机技术现状和发展趋势，研究了喷码机的组成及其分类情况，提出了生产线喷码打印机设计规格及其设计原则。针对设计原则和设计规格，提出一种生产线喷码机控制方法的软件总体设计方案。然后，本文深入研究并实现了整个控制方法中的三个关键技术，包括上下位机通讯方法、打印数据转换算法和同步策略、打印相位控制方法。上下位机通讯方法用于单片机和CPU的通讯；打印数据转换算法和同步策略详细阐述了打印数据的转换流程和打印数据高速、实时、同步传输的控制方法及其软件实现；在打印相位控制方法中提出了一套高效准确的相位检测算法，，接着分析相位误差，优化软件以减小误差，提高相位精度。接下来详细阐述了三个关键模块控制方法的设计及其软件实现细节，包括打印控制模块、墨路控制模块、人机交互模块。最后，为了证实该生产线喷码机控制方法的可行性和实用性，在原有硬件基础上对原型系统的主要模块进行了集成测试，并收到了预期效果。
[Abstract]:Nowadays, the technology of inkjet code printing shows the trend of high speed, low maintenance rate, humanized operation mode and intelligence. However, there is a huge gap between domestic and foreign countries in the technology of inkjet code printer. Can not meet the needs of production pipeline and the current stage of social needs. In view of the above problems, this paper will be based on the original hardware design. Research and implement a control method of production line printer based on embedded system. First of all, this paper introduces the domestic and foreign inkjet code machine technology status and development trends, the composition of the inkjet code machine and its classification. This paper puts forward the design specification and design principle of the printer in production line. According to the design principle and design specification, this paper puts forward a general software design scheme for the control method of the inkjet printer in the production line. Then, this paper deeply studies and implements three key technologies of the whole control method, including the communication method of the upper and lower computer, the algorithm of printing data conversion and the synchronization strategy. The method of printing phase control. The communication method of upper and lower computer is used for the communication between single chip computer and CPU. The algorithm and synchronization strategy of printing data conversion are described in detail, and the control method of printing data high-speed, real-time and synchronous transmission and its software implementation are described in detail. A set of efficient and accurate phase detection algorithm is proposed in the print phase control method. Then the phase error is analyzed and the software is optimized to reduce the error and improve the phase accuracy. Then the control method of three key modules and the details of the software implementation are described in detail, including print control module, ink control module, human-computer interaction module. Finally, in order to prove the feasibility and practicability of the control method, the main modules of the prototype system are tested on the basis of the original hardware, and the expected results are obtained.
