Automated system for technical diagnostics of electrical parameters of operative DC circuits
Resumo
The article considers the design features of automated systems for monitoring and testing backup power supply. The implemented complex of technical diagnostics makes it possible to measure and record the electrical parameters of the operative DC system in real time. Configuration is set up from the operator panel or personal computer.
Optimization of values of some parameters of linear power sources based on voltage regulators
Resumo
The article investigates the effect of the input capacitor value on the parameters of a linear power source. Dependency graphs, which help to select the optimum parameter value for a linear power source, are provided. The study was carried out using modeling in the program Multisim 11.
Presentation of modern network technologies for industrial control systems in educational process
Resumo
The article considers the principles of setting up the laboratory complex and the training procedure of modern information technologies for the development of industrial control systems of lower and upper levels (PLC and SCADA). The laboratory complex in question was set up on the basis of hardware and software by the Russian companies OWEN and INSAT.
Development of control system for stepper motor three-link manipulator
Resumo
The article considers the synthesis of control laws for stepper electric drives of three-link manipulator's kinematic links for implementing motion according to the prescribed program. To synthesize the required control laws, a mathematical model of the stepper drive is used, where the speed of the stepper motor is determined solely by the number of control pulses delivered to the stepper motor for a given length of time. The prescribed program of motion is given in tabular form.
Problems and approaches to object recognition in tasks of aerospace image processing
Resumo
The rapid development of new aerospace technologies has opened up new opportunities for the rapid acquisition of various space-time information by remote sensing of the Earth from space and airborne vehicles. This fact stipulates the intensification of the use of remote sensing data for landscape monitoring and assessment of the Earth surface for managing agriculture, forestry and water resources, smart use of natural resources, assessing ecological status of territories. The article considers the problems and the current approaches to object recognition.
Development of automation system for water level measurements on hydrological station with opportunity of monitoring data in cloud service
Resumo
Currently, there is a problem with the measurements of hydrological characteristics at hydrological stations in Kyrgyzstan. Consequently, mudslides, floods, improper distribution of water resources occur. At the moment the measurements are carried out by special workers, which leads to inaccuracies due to the use of outdated methods and the human factor. The article considers the problem of automation of water level measurements at the hydrological station "Alamedin" and sending data on Owencloud.
Structural synthesis of control device for tanks
Resumo
The aim of the article is to investigate the methods of synthesis of the control system that meets the basic engineering requirements to the main characteristics of the control system. Quality assessment of the processes of object management is carried out by using of functional relationships determined directly by the transient processes of the system under consideration.
