马钢2250热轧卷取区域软硬件冗余改进实践OA

To address the deficiencies exposed in the long-term operation of the original re-dundant design in the hot rolling coiling area,low-cost and highly effective improvement measures were implemented from both hardware and software aspects.In terms of hardware,redundant optimi-zation and upgrades were performed on the power supply system,network architecture,and key de-tection links.In terms of software,the signal fault-tolerant logic and the forced testing mechanism for backup equipment were improved.These improvements effectively shortened the downtime caused by failures and significantly reduced the risk of cobble caused by single-point failures,en-hancing the reliability of equipment operation.The practice shows that the redundant design pre-cisely matching the site operating conditions is an effective means to ensure the continuous and stable operation of the hot rolling coiling area.
