IMPROVING THE EFFICIENCY OF THE REMOTE FORM OF LABORATORY CLASSES ON CONTROL AND MANAGEMENT IN TECHNICAL SYSTEMS

Abstract

Based on the use of an experimental laboratory installation designed to determine the hydraulic characteristics of the downhole jet pump, a method of remote laboratory work with remote access of students to direct regulation and real-time control of mode parameters of a full-scale experimental installation is proposed. A simplified version of the laboratory work involves an operator who uses videophone remote conferencing and "cloud" technology using the free application Google Meet receives the necessary commands and directly launches and regulates the mode of operation of the experimental stand. For remote control and monitoring of the experimental setup, a structural scheme of laboratory work is proposed, which consists of personal computers (tablets, smartphones) of teachers and students connected to the "cloud" storage, smart sensors for broadcasting readings of manometers and flow meters, electric control latches and remote switch of electric power supply of the engine of the centrifugal pump. The actuator of the control valves contains limit and intermediate switches equipped with sensors that perform the function of remote monitoring and control via digital interfaces. The motor of the pump of the experimental stand is controlled by means of the wireless switch. For measurement of mode parameters the flowmeters with a pulse exit and digital manometers and manovakuumetry can be applied. To protect laboratory work, it is recommended to use the online services Google Classroom and Moodle.
