Introduction

The Automated Process Control System (APCS) is a type of control system that includes technical means that provide the replacement of physical and mental labor of a person with the work of machines for collecting, processing and outputting information, however, requiring the labor of operators to maintain and perform individual control functions.

APCS usually refers to a holistic solution that provides automation of the main operations of the technological process in production as a whole or some part of it that produces a relatively completed product.

The concept of "automated," in contrast to the concept of "automatic," emphasizes the need for human participation in individual operations, both in order to maintain control over the process, and due to the complexity or inexpediency of automating individual operations.

Components of APCS can be separate automatic control systems (ACS) and automated devices connected in a single complex. Such as Control and Data Acquisition Systems (SCADA), Distributed Control Systems (DCS), and other smaller control systems. As a rule, APCS has a single process control system in the form of one or more control panels, means for processing and archiving process information, typical automation elements: sensors, control devices, actuators. Industrial networks are used for information communication of all subsystems. The purpose of this course work is to implement the control system of the section of the automated packing and packaging line of paint products.

Rationale and selection of typical device nomenclature

The selected process control system includes various sensors, hydraulic cylinders, AC motors, robotic manipulators with a local control system, as well as auxiliary devices.

3.1. Sensor Selection

The sensor is a measuring means for generating a signal of measurement information in a form convenient for transmission, further conversion, processing and/or storage, but not directly perceivable by an observer. Electronic sensors are called electronic sensors. A single sensor can be designed to measure (monitor) and convert one physical quantity or several physical quantities simultaneously.

Sensor includes sensitive and converter elements. The main characteristics of electronic sensors are sensitivity and error.

Sensors are widely used in research, testing, quality control, telemetry, automated control systems and in other areas of activity and systems where measurement information is required.

There are three classes of sensors:

analog sensors generating an analog signal,

proportional to change of input value;

digital sensors generating sequence

pulses or digital code;

binary (binary) sensors that generate a signal

only two levels, on/off (in other words, 0 or 1).

Conclusion

As a result of this course work, a functional automation diagram and an electrical schematic diagram of the section control system of the automated packing line and packaging of paint products based on the Siemens Simatic S7300 PLC were developed. The components of the system were selected and their technical characteristics were given. The code of the control program was developed in the TwidoSuite environment.
