Automatic Optimization

The regulation of the coolant speed during convective drying in a stationary grain layer allows the maximum use of the amount of heat energy for drying the material. The paper presents the results of a study of the regulation of the coolant speed on an experimental drying plant for use in the automatic control system of a chamber grain dryer. The article also discusses the issues of energy saving efficiency in drying chambers. The possibility of automatic control of the main parameters control system using a microcontroller is analyzed.

Stone Cutting

This paper designs a PLC automatic control system in stone cutting. The author elaborated the stone cutting process, the system hardware/software design and the human-machine interface design process. This system is the collection of PLC, sensing detection, frequency converter, configuration control technology and advanced stone cutting process in an organic whole. The author designed optional automatic/manual function and parameters setting screen. The author added limit current protection and position protection, and designed function of automatic detecting cooling water shortage to protect the saw blade from damage. Also the designed equipment can automatic light and bell for alarm. Operation results show that, this system can meet the designed requirement, and can remarkably improve the quality of stone processing. This designed control system has high machining accuracy, high intelligence, full automation, perfect protection, friendly man-machine interface and simple operation.

Control Purpose

Boom–type roadheaders are basic machines used in underground mines for drilling roadways, in tunnelling and also for making underground buildings using trenchless methods. The article presents selected results of tests carried out in a semi–industrial scale, on a roadheader R–130, concerning behaviour of an innovative solution of system for automatic control of boom–type roadheader cutting heads’ movements. This important innovation, not known before in mining cutting machines, is the software control of cutting heads angular speed using a frequency converter. The text shows an impact of key values, from a perspective of an assumed control purpose, of programming device (setting system) parameters, achieving reference values for the actuators, on controlled facility behaviour when cutting a layered cement and sand block. The performance of the automatic control system without and with feedback to the setting system concerning an actual speed of cutting heads movement, which is important from the control system hardware perspective, was compared.

Commercial means of automatic control system of electricity metering, as is known, are installed on the input switchgear and measure the power consumption of all electrical consumers of this metering facility. Such data do not give a complete picture of electricity consumption on each floor of the metering facility, which in turn does not allow the implementation of energy saving measures. Also, these metering systems for electricity metering have a high cost. The article proposes a method of data processing and transmission to the server with their subsequent analysis of power consumption on each floor of the object under study using the ARDUINO microcontroller. Such an accounting system has a lower cost than an automatic control system of electricity metering industrial production. The article presents the scheme of implementation and types of current and voltage sensors. The topology of the measuring complex is also considered in the article. Such a topology can expand and keep not only the general account of a concrete floor, but also in the generality of each educational audience separately. Collecting such data on electricity consumption, it is possible to conduct a qualitative analysis of rational electricity consumption in the educational process, it means that for example in sufficient natural light artificial lighting in the classroom does not need to be used, or after laboratory tasks in a computer class, computers there is still some time. The introduction of energy-saving housing is performed due to the comparative characteristics of the power of gadgets, laboratory stands, etc. with the number of students in the group in accordance with the approved educational process. The algorithm of data processing, analysis of rational use of electric energy and comparative characteristics are implemented on the university server.

Oyster mushroom can grow properly at temperatures of 16–30 °C and relative humidity of 80–95%. Environment conditioning by spraying of water in mushroom house manually in the morning and evening as the temperature and humidity controling is less effective and highly bothersome. Using of technology can controlling temperature and humidity in a mushroom house automatically.  This research aims to design an automatic control system to control temperature and humidity in oyster mushroom house. Research is located at an altitude of 125 meters above sea level. Automatic control system with a setting point temperature of 25 – 30 °C and humidity of 80 – 95% was tested at mushroom house with dimensions of 4 × 2 × 2 m with a capacity of 600 baglog mushrooms.  The results show that the performance of daily temperature and humidity without control is respectively 24.10 to 35.19 °C and 64.28 to 99.90%. While the temperature and humidity with the control system are 25.10 to 30.09 °C and 80.84 to 99.90%, respectively.
