Abstract

The embodiment of the present invention discloses a device synchronization control method, device, terminal and system. When executed by the control terminal, the control terminal includes a first timing signal transmission interface and a first data signal transmission interface; the transmission of the first data signal transmission interface The rate is higher than that of the first timing signal transmission interface, and the method includes: receiving the operation information of the current functional operation sent by the second data signal transmission interface of at least two equipment terminals to be controlled through the first data signal transmission interface; analyzing the operation information , to determine the synchronization control identification of the next functional operation; to send the synchronization control identification to the second data signal transmission interface of at least two equipment terminals through the first data signal transmission interface, so as to control at least two equipment terminals according to the first timing signal transmission interface The sent timing signal and synchronization control flag execute the next functional operation in the next synchronization cycle. It greatly improves the synchronous control efficiency of the control terminal to each equipment terminal.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a device synchronization control method, device, terminal and system. Background technique [0002] With the development of automation technology, it has become a common method in the field of manufacturing to control the work of multiple equipment terminals synchronously by one control terminal. For example, in the process of producing integrated circuits, multiple lithography machines can be synchronously controlled by one control terminal. Simultaneous production of integrated circuits. [0003] The current device synchronization control method is that each device terminal and the control terminal complete the data interaction in the process of device synchronization control through three pairs of differential transmission lines. Among them, the first pair of differential lines is used to provide synchronous clocks, and the other two pairs of differential lines Th...
