过程控制与优化
概述
过程控制和优化 (PCO) 是在不违反过程约束的情况下调整过程以维持或优化一组指定参数的学科。 PCO 市场受到对节能生产流程、安全和安保问题的需求不断增长以及能够可靠预测流程偏差的物联网系统开发的推动。从根本上说,可以调整三个参数以影响最佳性能。 - 设备优化:第一步是通过检查运行数据以识别设备瓶颈来验证现有设备是否被充分利用。 - 操作程序:操作程序可能因人而异或因班次而异。工厂的自动化可以提供很大帮助。但是,如果操作员控制并手动运行工厂,自动化将无济于事。 - 控制优化:在典型的加工厂,例如化工厂或炼油厂,有数百甚至数千个控制回路。每个控制回路负责控制过程的一部分,例如保持温度、液位或流量。如果控制回路没有正确设计和调整,则过程会低于其最佳值。该过程的操作成本将更高,并且设备会过早磨损。为了使每个控制回路以最佳方式运行,识别传感器、阀门和调整问题很重要。已充分证明超过 35% 的控制回路通常存在问题。持续监控和优化整个工厂的过程有时称为绩效监督。

Case Study
Industrial Workforce Mobility for Improved Safety & Operations
Huntsman Corporation, a global manufacturer and marketer of differentiated chemicals, undertook an aggressive program to eliminate injuries, product defects, and environmental releases at their Port Neches facility. Termed “Project Zero”, this program required a completely mobile solution to empower operations and maintenance personnel to capture defects, track work progress and make process and safety related decisions in real-time.
Case Study
The BAUR Versand Increases Staff Efficiency
For the operation of the warehouse, including goods receipt, high rack warehouse, sorting equipment and conveyor belts, BAUR uses multiple conveyor systems and 14 stacker cranes (RBG). These are monitored and controlled by more than 60 programmable logic controllers around the clock. The messages run in the central WinCC visualization system together in the control room. Baur wanted to avoid unnecessary travel and thus increase the efficiency of staff deployment and save time.

"cab" Selects Signal Towers from WERMA
Clearly identifiable labelling and product marking is an essential part of any business whether it is on individual components, finished products or packaging. Europe's largest manufacturer of labelling and printing machines, supports its reputation for innovation, reliability and durability by the careful selection of essential bought in components for its own operation. This is why cab selected the new innovative modular signal tower series KombiSIGN 40 from WERMA.
