Jet printing control method and system of array type precise jet printing device

The invention relates to a jet printing control method of an array type precise jet printing device. The jet printing control method comprises the following steps: designing a data transmission and control protocol of jet printing, adopting a jet printing control system of the protocol and solving the problems of generating the jet printing work of a jet head array consisting of 2-120 nozzles, quickly transmitting data, delivering and cooperating tasks, and precisely and synchronously jet printing. The jet printing control method is applicable to the fields such as printed circuit board (PCB) high-speed jet printing, ceramic printing, Ecrro Luminescence (EL) cold light plate printing and the like. Based on a three-layered hardware framework consisting of an upper computer, a NUSB central-controlled system, and a spray head control board card array, a jet printing data structure, a communication and control protocol, and a jet printing work scheduling algorithm are designed, and the jet printing work is composed of jet printing igniting data, planned scheme order and temporary scheme order. The system dispatches the jet printing work according to the planned scheme or temporary scheme; the upper computer generates the work data and order, NUSB performs order analysis, work management, task distribution, execution control and statistics; and the jet head control board card executes the jet printing task.
