Vovna A. Methods and means of the creation of computerized optical electronic methane and dust concentration measuring systems for mine atmosphere

The dissertation is devoted to the development of methods and means of improving the measurement system of methane and dust concentration in mine atmosphere. The scientific-applied problem of creation and technical implementation of new science-based approaches to computerized information and measurement technology has been solved, which allows developing a high-speed high-precision optoelectronic measuring system within the complex providing aerogas coal mine safety. Theoretical foundations of information parameters formation and description of destabilizing factors in measurement control of dust and gas components concentration have been developed. Models of measuring channels of methane and dust concentration, which take into account the effect of destabilizing factors complex on the parameters of optoelectronic measuring devices, have been developed and studied by the optical absorption method. New structures and algorithms of measuring channels of methane and dust concentration have been developed, their metrological certification was made taking into account the peculiarities of operating systems, allowing control of the lower threshold of dust-gas mixture explosiveness, which has applied significance. The experimental studies of the designed gauges, which confirmed the correctness of the tasks and mathematical apparatus used in the preparation of basic scientific positions, have been carried out.
