Abstract
In this paper, use micro-controllers, computers, communications, field bus, java and other technologies for flat screen printing machine constitutes control system architecture what horizontal dispersion, vertical hierarchical, realized the goal of information and operation management of decentralization and decentralized control, designed the framework of system, described the key technology of system development. User login through a browser, not only can operate a remote device and to obtain field data, but also through the operation of remote network cameras to observe the real production process. Moreover, CAN bus to transmit data with high precision and strong performance, and the running status of devices and production status of high transparency, can achieve the goal of digital printing and dyeing machinery. Not only that, but also saves the connection cable and a variety of installation and maintenance costs.
