The article found that in the conditions of re-equipment of all enterprises based on resource-saving technologies and computerization, their work is still associated with significant material losses as a result of insufficient development of the transport, technological system of metal support and regime automation. It was established that the operation of the communication system with a moving object is complicated by the influence of external factors of metallurgical production due to the reduction of the quality of communication. The problem of reliable and uninterrupted operation of the information transmission channel is closely related to the existence of parasitic electromagnetic connections and interference, the presence of which impairs the efficiency of its operation. Therefore, the construction of an interference-resistant data transmission channel and the proposal of a hardware implementation of the communication device with the object are urgent tasks. According to the international standard EN 50170 for the industrial network (PROFIBUS), certain requirements are established for the speed of signal transmission (1500 Kbit/s) and the length of the segment (200 m), which the communication device with the object must provide. The use of existing communication devices with the object is not possible, since none of them is suitable under technical or economic conditions. Wired communication lines, a radio channel, an optical fiber line, an optical signal or infrared rays are often used as a medium for transmitting data or commands in remote control systems. It has been established that the use of ultrashort radio waves is the most appropriate for use in a communication device with an object under these operating conditions. This type of communication can be implemented on an ordinary radio station, the calculation of whose parameters has a well-known algorithm. The progress of recent years in the field of increasing the bandwidth of channels is significantly related to the development of digital data transmission technology, their synchronization, effective coding and reliable transmission.
