工业互联网：联接之魂，智慧之躯；can总线常见的七种故障：如同七个挑战，每一个都需克服。

一、工业互联网：生于联接，智慧延伸至每一处

美国GE公司给出的定义是：“通过全球的工业系统与先进计算、分析、低成本感知能力与互联网带来的新联接水平相互融合而持续发生。”

日本的“互联工业”是一个高度近似的工业转型升级活动，其内涵是通过实现物、机器设备、企业、人、数据及生产和消费的相互联接，由联接创造新价值。

中国工业互联网产业联盟定义为：“以机器、原材料、控制系统、高级建模分析为基础，实现智能控制运营优化和生产组织方式变革。”

二、“Industrial Internet" and its Impact on Manufacturing Industry

The Industrial Internet, also known as the Fourth Industrial Revolution, is a new era of interconnected systems that integrate traditional manufacturing with advanced technologies like IoT (Internet of Things), AI (Artificial Intelligence), Big Data Analytics, and Cloud Computing. It aims to improve efficiency, productivity, and decision-making in various industries.

Smart Factory: The industrial internet enables the creation of smart factories where machines can communicate with each other and make decisions autonomously without human intervention.

Real-time Data Analysis: With the ability to collect vast amounts of data from sensors and devices, manufacturers can analyze it in real-time to optimize production processes.

Predictive Maintenance: By analyzing equipment performance data, predictive maintenance allows for proactive maintenance schedules reducing downtime and improving overall efficiency.

Supply Chain Optimization: The industrial internet enables better collaboration between suppliers, manufacturers, logistics providers through real-time information sharing leading to improved supply chain management.

III.can总线常见的问题：
