The authors develop standards and design of pre-emergency, emergency and post-emergency control of mine technological environment and electric machinery activity. The electric machinery operation parameters to be controlled are energy supply of explosion-proof electric machinery, cable integrity and improper access to the machinery; the control objects are switchers and starters within an extraction district. The technological environment parameters to be controlled are gas content, including CH 4 , CO, CO 2 and O 2 , variation in mine air pressure, light, sound, temperature, acceleration or dislocation of central control unit housing. The article presents engineering solutions on subsystems of data reading, processing and storage. CONCLUSIONS 1. The authors have developed the basic standards and characteristics of PECS meant to accomplish continuous integrated control over state of electric equipment and air in coal mines and prevent from the equipment operation infringement that, together with impermissible methane concentration, is the cause of explosions in mines.2. In cases of emergency, the systems run the objective documentary control and record of the mine area parameters in the accident and post-accident mode.3. The authors present engineering design of the data processing, storage and retrieval. 4. The designed and manufactured brassboards of the PECS subsystems have successively passed probation. Engineering design of the remote wireless data transmission, low-voltage network communication and program support of the data acquisition and transmission subsystem have been developed.
This program describes the experience over the ages and it was improved as the main goals of technology training used by specialty "Automation and Control" at the Department of Automation of Production Processes at the Karaganda State Technical University, within the program as the international distance educational project "SYNERGY" by the fallowing research direction such as: in process control and management for computer development and microprocessor systems; the government program of industrial-innovative development; the profile magistracy as a new educational system; the complexes of virtual practical-laboratory; on the basis of industrial equipment also on the basis of various control were created the stands; the new stands are designed and manufactured; the existing training stands are modernized; the contemporaneity educational standards are taken and created.
As a result of R&D, a measuring system for controlling the thickness of the HDPE/LDPE (high-density polyethylene/low-density polyethylene) polymer geomembrane was developed using automation equipment. The relevance of this work consists of the development of a domestic, relatively inexpensive system for controlling the thickness of the HDPE/LDPE polymer geomembrane in production conditions based on modern equipment for enterprise automation. The scientific novelty consists of the use of original design solutions in the development of hardware and software complex mechanisms that allow controlling the thickness of the HDPE/LDPE polymer geomembrane layers along the entire width of the shaft, excluding deformation of the film as a result of foreign bodies entering during extrusion, cuts, monitoring the quality of the film in real time, as well as the possibility of analyzing the measured parameters in the database of the automated system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
