Purpose and purpose of development

Purpose of development: development is intended for control of the automatic transfer line of production of plates heat-insulating the reinforced and quality providing the manufactured products, the high performance, high reliability and also for reduction of number of service staff.

The purpose of the development is to create a management system that provides the following capabilities:

line control from the operator console;

development of emergency situations on the line;

Ease of start-up and maintenance

Providing the price/quality - price/productivity criterion required for high line competitiveness;

achieving economic impact;

Compliance with environmental requirements .

Conclusion

The reason for the development of this diploma project was the situation in the Russian public sector related to the increased consumption of energy resources for heating premises. The technology described in the introduction section of this project makes it possible to produce construction material - heat-insulating reinforced plates with high heat-insulating ability.

In order to automate the production of plates, an automatic line was developed. The line is controlled by a control system, which is discussed in this diploma project.

Based on the analysis of sensors, actuators and the algorithm of the line, a structural diagram was developed. It showed the response of the actuators to the signals coming from the sensors, as well as the sequence of switching on the actuators within the device and the sequence of switching on the devices themselves.

Based on the data on the speed of the actuators and the algorithm of the line, a cyclogram of the line was developed, the time of one cycle of operation was calculated, corresponding to 100 mm of the manufactured product, which was 5.3 seconds. The performance of the automatic line was calculated. It amounted to 234580 m2 of manufactured products per year.

The SIEMENS SIMATIC S - 7,226 XM controller was selected to meet all requirements. On its basis, a schematic diagram was developed giving a detailed idea of ​ ​ the operation of the control system.

Based on the algorithm of the line, a program embedded in the controller was developed, a fragment of which is given in this diploma project. The program is written in the STL mnemonic code language in the STEP 7 MicroWin V3.2 programming environment for SIMENS SIMATIC S-7 controllers.

For installation of a control system the case with dimensions was chosen: 1800х1200х400 by which overall dimensions the location of the controller, converters of supply voltage and puskozashchitny devices was determined.

An automatic fire extinguishing system was developed and the necessary number of sprinklers was calculated to extinguish the fire with an area equal to the area occupied by the automatic line. To ensure page safety, 25 sprinklers were required.

The economic effect of using the management system developed in this diploma project was calculated. It amounted to 138602.85 rubles.

The control system of the automatic production line of heat insulation reinforced plates fully satisfies the technical assignment.
