Multi-module data transmission communication system

Abstract

The invention relates to a multi-module data transmission communication system, which is provided with a human-machine interface which is connected with a PLC programmable controller, wherein a DeviceNet bus master station unit is arranged on the PLC programmable controller, and the PLC programmable controller is connected with and controls various execution mechanisms and various detection mechanisms of a hydraulic press through a plurality of slave stations which are correspondingly connected with a plurality of splitters connected with the DeviceNet bus master station unit; the plurality of the slave stations comprise slave station TRIO controllers of a control system, power mechanism slave stations, rear lower right beam slave stations of the hydraulic press, front lower left beam slave stations of the hydraulic press, and operation panel slave stations; and the plurality of the splitters comprise control box splitters, power mechanism splitters, rear lower right beam splitters, front lower left beam splitters and operation box splitters. Remote control modules in various distribution boxes and the PLC programmable controller and the TRIO controllers in a control box are taken as slave stations and connected with the network through a DeviceNet network system, remote I / Os are arranged inside the various distribution boxes respectively, and the slave stations are communicated with a master station module of the PLC programmable controller through bus DeviceNet connection.

Description

technical field [0001] The invention belongs to the technical field of automatic control of hydraulic presses, in particular to a multi-module data transmission communication system applied to an automobile stringer hydraulic press by an industrial field bus during multi-module data transmission. Background technique [0002] For many years, the process industry has been committed to developing a single, open standard for addressing various types of equipment on site. PLC programmable controllers are used for centralized control. The system control accuracy is low and the operation is inconvenient. All digital quantities and analog Quantitative I / O points are wired from the PLC programmable controller cabinet. With the rapid development of my country's equipment manufacturing industry, forging equipment is developing rapidly in the direction of large-scale, complex, modern, and automated. The corresponding increase in I / O points of complex products will lead to a large amoun...

[0002] For many years, the process industry has been committed to developing a single, open standard for addressing various types of equipment on site. PLC programmable controllers are used for centralized control. The system control accuracy is low and the operation is inconvenient. All digital quantities and analog Quantitative I / O points are wired from the PLC programmable controller cabinet

With the rapid development of my country's equipment manufacturing industry, forging equipment is developing rapidly in the direction of large-scale, complex, modern, and automated. The corresponding increase in I / O points of complex products will lead to a large amount of wires, complicated wiring, and high failure rates. , has brought a lot of inconvenience to on-site maintenance, seriously affected the production, and has not adapted to the production requirements of modern enterprises.
