The Industrial Internet of Things (IIoT) is much more advanced than the commercial IoT, primarily due to the prevalence of connected sensors in the industrial world, which are the “things” in the IoT. Hundreds of millions of connected wired and wireless pressure, level, flow, temperature, vibration, acoustic, position, analytical, and other sensors are installed and operating in the industrial sector, and millions more are added annually, increasing value with additional monitoring, analysis, and optimization. These sensors connect to a variety of higher level software platforms, both on- and offsite.
On-site connections are often via a local intranet, creating an Industrial Intranet of Things. Offsite connections are usually made through the Internet, often via a cloud-based storage system. These higher level software platforms include control and monitoring, asset management, and specialized data-analysis systems. At remote data-analysis centers, sophisticated big data analytics are performed by dedicated experts to reveal patterns, problems, and solutions.
