Application number: 201310669221.3 patent for invention, which discloses a PLC control system, including a remote I / O module and a PLC master module. The remote I / O module is a VersaMax remote I / O module. Under the premise that the original Genius remote I / O module is replaced with the new VersaMax remote I / O module, the GeniusBus communication method is mainly used to exchange data with the GE90-30PLC module to realize mutual communication with each other. This control system can not only reduce The number of CPU control modules used in the main station PLC module also greatly saves the use of control cables, reduces costs and manual maintenance, makes up for the defects of the old generation of remote I / O modules that are not produced, and facilitates the unification of spare parts Ordering and replacement, but the main purpose of the invention is to reduce the number of equipment and cables used, thereby achieving the purpose of reducing costs and labor maintenance. There is no improvement for the control system and monitoring method of the rolling and continuous rolling transmission system; the application number is: The utility model patent of 201320111098.9 discloses an electrical monitoring system for the main electrical room of a rolling mill, including a programmable controller for the machine unit, a programmable controller for the vertical roller, a programmable controller for the oil depot, a programmable controller for the hydraulic station, and a programmable controller for bearing pad monitoring The switches are respectively connected to the switch, and the output of the switch is connected to the computer in the main control room. This utility model adopts the network technology based on Profibus and the Internet to implement networking with each programmable controller PLC. It is fast and effective, easy to operate, safe, environmentally friendly, The feature of wide application can play the role of analyzing the hidden dangers of the equipment according to the historical trend and troubleshooting the fault point, and this utility model can dynamically understand the equipment information and the state of the equipment chain signal, analyze the hidden dangers of the equipment, solve the equipment failure in time, reduce During unplanned shutdowns, production runs smoothly and energy is saved. However, this utility model only realizes field-level monitoring, and does not realize the integrated monitoring of the entire system, and the operating data of the system is not uploaded to the server for safe and reliable storage.

Abstract

The invention discloses a PLC-based continuous rolling transmission monitoring system and a monitoring method thereof, comprising an upper monitoring unit, an intermediate network unit and a plurality of on-site monitoring units, the upper monitoring unit communicates with the intermediate network through a second communication module The unit communicates, and the intermediate network unit communicates with the on-site monitoring unit through the first communication bus. The invention also discloses a PLC-based continuous rolling transmission monitoring system and its monitoring method. According to the control parameters of the unit And the operating parameters of the unit, the working status of the rolling unit is controlled through the PLC control transmission device, and the working status data of the rolling unit can be sent to the operator station in the upper monitoring unit through the network for monitoring. The control system and the monitoring system realized by the present invention have a three-level network structure, and data communication is realized through switches between each network structure, which can conveniently realize the hierarchical flow of monitoring information flow, and is suitable for the control needs of different managements.

Description

technical field [0001] The invention relates to the technical field of steel rolling in steel mills, in particular to a PLC-based continuous rolling transmission monitoring system and a monitoring method thereof. Background technique [0002] Rolled steel products play a pivotal role in all walks of life in modernization, including housing, petrochemical, electromechanical, automobile and other industries are inseparable from rolled steel products. The main production process of contemporary steel rolling technology is different from the old ones in the past, and the products are directly rolled into shape. In the past, the control method was manual analog quantity control, and the controller adjusted the input speed setting of the speed control device; if the system detects that the device is in a fault state, it will stop directly, and the operator and maintenance personnel cannot query the fault information; the transmission device and The communication between the conso...
