Example Embodiment

[0020] The present invention will be further described below with reference to the drawings and embodiments.

[0021] Such as figure 1 , The power circuit adopts AMS1117 voltage regulator in this system to provide 3.3V working voltage to the system. AMS1117 is a low-power positive linear voltage regulator chip with high precision, high efficiency and high reliability. Its internal integrated overheat protection and current limiting circuit. AMS1117 has a wider input voltage range, higher conversion efficiency, smaller ripple coefficient and better temperature stability. The 5V power supply is used as the input of AMS1117, and a stable 3.3V voltage can be output after voltage regulation.

[0022] Such as figure 2 , The clock circuit adopts an active crystal oscillator as the basic clock of the system, and uses hardware frequency division to obtain the required frequency. 74HC590 is an 8-bit high-speed binary counter with data output in parallel. The frequency of the selected activ...

Abstract

A continuous ink jet type code spraying machine control system with double ARM architectures is suitable for the code spraying field. The control system is composed of a power circuit, a clock circuit, a digital-analog interface circuit, a sine wave generating circuit and a power amplifying circuit. According to the system, the optimal phase is obtained through a quantitative processing technologyand a statistic method, and thus the work reliability and stability of the control system are improved, the circuits have good real-time performance, stability and reliability, and the system is moreflexible, higher in performance and good in anti-interference performance.

Description

technical field [0001] The invention relates to a continuous inkjet printer control system with dual ARM architecture, which is suitable for the field of inkjet coding. Background technique [0002] The theory of inkjet printer was born in the late 1960s, and it was not until the end of the 1970s that the world's first commercial inkjet printer was produced. After half a century of development, the current technology has become mature. Since 1992, the emergence of the first domestic manufacturer of inkjet printers has ended the monopoly of foreign products. However, due to technical limitations, domestic inkjet printers currently have problems such as unclear printing, slow speed, no automatic cleaning, and nozzle clogging. Most of the inkjet printers currently used in the market are produced in the United States, France, Britain, Japan and other countries. [0003] The inkjet printer uses charged ink particles to print patterns, characters and numbers on the surface of v...
