ANALYSIS OF EXTERNAL AND INTERNAL INTERFERENCES OPERATING IN METALLURGICAL PRODUCTION

Abstract

The article analyzes the operation of means of receiving and transmitting information signals in extreme conditions of metallurgical production. It is proved that the distribution channel has a large heterogeneity of components that determine the energy losses of the information signal, especially optical. The energy losses of the optical information signal in the elements of the primary converter are lower in magnitude than the losses in the external environment. Therefore, issues related to increasing the reliability and error-free operation of the information transmission channel against the background of existing electromagnetic connections and interference in production conditions, the presence of which affects the quality of its operation, are considered. An analysis of measures that increase the noise immunity of primary converters has been carried out. It has been found that the features of the production process leave a certain imprint on the composition and type of interference that act on the useful signal during its transmission through the information channel and general approaches to combating interference are not sufficiently effective. It is not possible to influence the interference itself and increase the power of a separate signal, therefore the issue of joint protection of the channel and information signal is considered. Production interference that affects the quality of operation of means of control of technological parameters, as well as devices and elements of the system that ensure their connection with the production facility, has been studied. An analysis of production interference has been carried out and an assessment of the impact of these destructive factors of metallurgical production on the quality of information transmission has been made. It is established that the energy losses of the optical information signal in the elements of the primary converter are incomparable in magnitude with the losses in the external environment. The use of special signals that have high resistance to interference during their transmission is proposed, as well as approaches to the improvement and development of fundamentally new structures of receiving devices that allow detecting information signals in the presence of significant interference. This allows solving the problem of increasing the reliable and error-free operation of the information transmission channel in extreme production conditions.
