Аннотация

In this text the systems of automation of technological processes are described in detail. Here the hierarchical structure of automation is described in detail. Different variants over of decision of tasks of automation are brought. Structural model of the requirements produced to automation presented as a pyramid. A picture is in-process presented, where a pyramid is divided into levels. Principles that operate for every level at the decision of tasks of automation are here presented.

Also here are given determinations of devices of sensors and executive mechanisms and also functions that execute these devices are indicated. Examined separately in every level the located devices, functions that they execute, and also dwells, in every level.

Information is widely exposed about an exchange by information between levels. Types over of informatively-technical connections are here brought between levels.

At the end of text basic advantages over and disadvantages of automation are brought.
