Key factors for design verification of industrial IoT sensor nodes

摘要

As the IoT continues to expand, we see a large interest in the use of distributed sensor nodes in the industrial space. However, many industrial applications fall into what is commonly referred to as "brownfield" applications, which require new hardware/software solutions to co-exist with existing solutions. In addition, many of these in situ solutions may be more than 20 to 30 years old. So how do you bring new technology to an already extant install base?First, we need to understand the nature of the current problem set being addressed. In the industrial space, we are frequently talking about the online monitoring of existing physical processes. These could range from monitoring the temperature of the content in a crude oil pipeline to monitoring the amount of chlorine in water as it leaves a water treatment facility. In the industrial space, they tend to focus on simplicity of installation and reliability of the sensor technology. In some cases, the state of the art may not have progressed very far; that is, the good old way of doing it may be good enough. In other applications, there may be a significant advance in the technologies that could result in a lower cost of ownership and better reliability.
