An online sound and light alarm system for strip steel cpc deviation correction

Abstract

An online strip steel CPC (center position control) audible-visual alarming system belongs to the technical field of strip steel production. The system comprises a CPC device, an S7400 PLC (programmable logic controller), a switch value output module, an audible and visual alarm, an upper monitor reset button, and relevant communication wires, leads, wiring terminals and the like. When deviation of the strip steel from a central line exceeds a preset deviation value, control commands are output by the S7400 PLC through the switch value output module, and audible alarm and visual blinking alarm are generated by the audible and visual alarm simultaneously to alert an operator to take process actions such as reducing speed, adjusting tension and the like, so that the strip steel can be led back to a normal position as soon as possible. A controllable button is further added to an upper monitor interface to improve system functions. The controllable button is used for resetting the audible alarm while the visual blinking alarm continues, so that form of an alarming function is diversified, the alarming function is enhanced, humanization is achieved, and continuous noise disturbance is avoided. The online strip steel CPC audible-visual alarming system has the advantages that shutdown rate of a whole production line due to overrun of the center position control can be reduced greatly, and the online strip steel CPC audible-visual alarming system has fine popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of strip steel, and in particular provides an on-line acousto-optic alarm system for strip steel CPC (Center Position Control) deviation correction, which can be widely used in various deviation correction systems for strip steel production. Background technique [0002] In order to ensure the continuous and stable production of strip steel, the strip steel production line is usually equipped with dozens of sets of strip steel CPC deviation correction devices. In the current strip production line, the CPC device usually detects the offset of the strip and the offset of the hydraulic cylinder, and displays it in real time on the upper monitoring screen. When the offset exceeds the set offset, a color alarm will be displayed at the CPC offset on the screen. . Although this color alarm plays the role of strip steel deviation alarm, the alarm form is single and the warning effect is not strong. In view of the ...
