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
Dedicated License Management for B&R
More and more functionality of machines and manufacturing facilities is determined by the controller software, production settings, and machine data. This essential know-how of the machine producer must be protected and shielded from manipulation by competitors, organized crime, or simple incorrect use. New business models need to be supported. And any solution has to be highly reliable and work even in harsh environments.

Case Study
ZTE's Integrated Battery-DG Hybrid Energy Storage Solution
For cities and companies involved in new construction or site transformations, areas with unstable or poor quality power can cause problems and diesel and other similar generators can add another one: expense. In the context of high traditional energy prices, the trend of low-carbon, energy saving, environmental protection, renewable energy will become increasingly important in the field of communications power supply. Especially along with its technology improvement, the traditional renewable energy hybrid power solution can’t fully meet with customer’s demands, especially on the energy management, energy monitoring, system upgrading, product efficiency, environment adaptability, etc.

Case Study
Diesel Direct Uses the Cloud to Persevere Through Power Outages
The company relied on the expertise of a staff of experienced billing agents, account managers and administrative specialists whose primary tools were one giant customer database built on Microsoft Access, Exchange email and the anachronistic but effective use of paper invoices delivered via fax or snail mail.This process was effective until Irene made it clear that if power went out in the main office Diesel Direct wouldn’t be able to send out that fast flurry of invoices every day. And without that, their cash-flow situation would be greatly impacted very quickly.Their clients, fleet managers for distribution companies, understand quickly how Diesel Direct can save them money by letting them trade a few extra cents per gallon of fuel for the FTE cost of having their own people handle the fuelling and maintenance and reporting, plus the cost of having the truck off the road while they’re doing it. Diesel Direct’s services allow them to skip most of that. The model doesn’t require a lot of technology, but Diesel Direct can’t accomplish anything if its minimal IT infrastructure is offline for any length of time.
