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
OTA Software Updates for Smart Energy (gridX)
gridX has a requirement for over-the-air software updates for their gridBox devices and used the Yocto Project for their builds. The driver for the requirement was having the ability to quickly support new features, as well as deploying bug fixed and path known security vulnerabilities. New software updates with a US stick manually to all gridBox devices in the field would be prohibitively expensive and labor-intensive.

Canon Processes Data from More Than 1 Million Printers 5x Faster
Canon wanted to build an infrastructure to enable IoT system to process large amounts of data received from more than 1 million multifunction printers, and support 2x anticipated growth in the number of printers connected to the IoT, and ensure migration to the IoT platform to minimize disruption to global office-products business operations, and deploy a easy-to-manage disaster recovery system to reduce the switchover time in the IoT environment.

National Instruments selected Attivio Platform for Superior Search Functionality
National Instruments was concerned about the future state of its enterprise search solution. Microsoft’s FAST ESP was no longer offered as a stand-alone product and it was marked for end-of-life, effective July 2013.
