(Summary description)The technology of sensors has always been of great interest in the field of industrial automation. Over the years sensor fusion has been a hot topic in industrial automation production and manufacturing. The concept of sensor fusion, which started in the 1960s, has evolved to a new level, i.e. data fusion is a new topic that is closely linked around sensor grids, and the discussion of sensor grids covers (wireless) sensors, the Internet of Things, etc.

The technology of sensors has always been of great interest in the field of industrial automation. Over the years sensor fusion has been a hot topic in industrial automation production and manufacturing. The concept of sensor fusion, which started in the 1960s, has evolved to a new level, i.e. data fusion is a new topic that is closely linked around sensor grids, and the discussion of sensor grids covers (wireless) sensors, the Internet of Things, etc.
Sensor fusion can also be understood in two ways: a priori sensor knowledge (indirect fusion) or from the ground up (direct fusion). That is, a simpler idea arises: use all available information, combine it and form better information. Better information means more accurate, more complete and more reliable information than a single or independent data source. The distinction and classification lies in how the data is combined. Hypothetically, batches are identified, verified as well as controlled by a large number of machines or various production steps. Later in the production process, a large amount of information can be used, but since much of the information currently does not pass the inspection of the controller of the given application/machine, the information is not not shared. This makes sensor fusion particularly important if information is available, production can be adapted, inspection systems become simpler and cheaper, and waste can be reduced.
Sensor fusion can significantly facilitate the production of small batches in manufacturing, as the data it collects and the information on individual objects enables more flexible production. In early production processes, more and more users are moving from final inspection to in-line inspection. By combining the results of inspection stations with sensor data from the manufacturing process, errors can be detected much more quickly. Sensor fusion is particularly useful for existing plant energy management, condition monitoring and new systems requiring a large amount of information for predictive maintenance. A lot of information is available, but collecting it exclusively is not the end goal. For example, energy data can be collected from devices such as flow meters or AC drives; vibrations are measured by sensors within the controller.
