Special PCI (Peripheral Component Interconnect)-based hydraulic machine motion control method and controller

Abstract

The invention relates to hydraulic machine motion control, and provides a control board card and a controller. The control board card has low cost, high reliability and simplicity in use and maintenance, and is combined with an industrial personal computer to form a control system, and the controller is directly matched with an actuator through signals. The technical scheme is as follows: the special PCI (Peripheral Component Interconnect)-based hydraulic machine motion controller comprises an analog input module, an analog output module, a TMS320F2812 digital signal processing module, an EQ2C8Q208 logic circuit conversion module, a PCI9054 bus data communication module, a switch value input circuit module and a switch value output circuit module, wherein the Q2C8Q208 logic conversion circuit module is connected with the modules. The controller provided by the invention is mainly used in the motion control of a hydraulic machine.

Description

technical field [0001] The invention relates to motion control of a hydraulic press, in particular to a PCI-based special motion controller for a hydraulic press. Background technique [0002] At present, my country's industrial production has entered a stage of rapid development. At the same time, the demand for various controllers has greatly increased in today's increasingly automated production. In high-tech fields such as aerospace, large-scale equipment manufacturing, and electronic information, higher requirements are put forward for the controller's stability, anti-interference, precision, speed and other indicators. But now the domestic motion controller market is still dominated by foreign products, and the high-level controller market is almost monopolized by several foreign companies, which means that our country now lacks a low-cost, high-reliability motion controller with independent intellectual property rights. controller.
