Embodiment Construction

[0034] Referring to Figure 1, the electrical control system of the printing machine ink supply control system adopts a dedicated control computer and a multi-layer embedded control system. The special control computer is equipped with special control software, which realizes remote monitoring, diagnosis and maintenance through the internet, and realizes remote updating of each control layer program of the multi-layer structure embedded system. Figure 12 It is a flow chart for the local implementation of the remote update of each control layer program of the multi-layer structure embedded system. Ethernet communication is used between the dedicated control computer and the multi-layer embedded system to monitor and control the multi-layer embedded system in real time, to realize initialization, zero point adjustment, ink volume adjustment in the ink area, mechanical gap compensation adjustment, status query, Fault monitoring and diagnosis, printing ink volume preset and other ...

Abstract

The invention relates to an automatic control system for ink quantity of a printing press and is provided with a computer containing control software and an embedded control system with a multilayered structure. A centralized control layer is a central control unit, which adopts an ARM7 or an ARM9 inner core processor and a UCOSII embedded real-time multitasking operating system. An Ethernet interface communicated with the computer and an outside network is arranged, thus a data exchange layer and a execution control layer can be controlled and monitored through a 485 bus interface; the data exchange layer is a communication unit and is equipped with a 485 bus interface used for the data information exchange between the centralized control layer and the execution control layer; the execution control layer is an ink slice driving unit used for receiving the control information from the computer and the centralized control layer so as to accurately control the position of the mechanical executive component and feedback the operating state of the execution control layer in real time.

Description

technical field [0001] The invention relates to the control of the ink supply of printing machines, in particular to an automatic control system for ink supply of printing machines which uses computer and electronic automation control technology to precisely control the ink supply process of printing presses, which belongs to the field of computer and electronic automation. field of control technology. Background technique [0002] Printed matter should be able to truly describe a variety of colors and an ever-changing world. The color performance of printed matter is directly related to the ink supply of the printing machine. If you want to achieve detailed color expression, you need to accurately control the ink supply of the printing machine. In addition, most modern printing jobs are short-run jobs, and a pair of printing plates can print thousands or even one or two hundred prints at a time, so the printing plates must be replaced frequently, and the colors of each pri...
