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。

Commercial Building Automation Boosts Energy Efficiency
One of the challenges to building automation is the multitude of non-interoperable communications protocols that have evolved over the years. Buildings have several islands of automation. Bridging the islands of different automation without losing the considerable investment in each specialized control network is the main focus in this solution.

Maximizing Error-proofing in Manufacturing with MES/MOM Controlled Assembly Tools
This document summarizes the error-proofing solution a leading heavy machinery manufacturer implemented and standardized on in order to greatly reduce product defects due to improperly fastened bolts in transmission systems. Electric assembly tools called nutrunners are used by assembly line workers to fasten bolts to a predetermined torque measurement. Their decision to implement a manufacturing execution system (MES) or manufacturing operations management (MOM) software to both ‘monitor’ and ‘control’ all aspects of the assembly tools and line worker processes yielded unprecedented results by reducing bolted joint failures and Warranty claims by 94%.
Case Study
Energy Smart Generation by Unatec using Carriots
Energy generation and management, when not optimized, severely damages the results. If costs are not closely controlled or the production is not predicted accurately, profit can be dramatically diminished or even lead to losses. It is therefore mandatory for energy producers to optimize the management to maximize profitability.
