COLLECTOR ENGINE CONTROL SYSTEM

Abstract

One of the main features of the current stage of scientific and technological progress is the wider use of microelectronics in various sectors of the economy, which is constantly growing. The role of microelectronics in the development of social production is determined by its almost unlimited possibilities in solving various problems in all sectors of the economy, its profound impact on the culture and life of modern man. Particular attention is now paid to the introduction of microprocessors that solve the problem of automation of control of mechanisms, devices and equipment. Adapting the microprocessor to the conditions of a particular task is mostly done by developing appropriate software, which is then stored in program memory. Hardware adaptation in most cases is performed by connecting the necessary integrated circuits and I / O that meet the problem to be solved. In the given work the microprocessor system of regulation of turns of the collector motor of a direct current is developed. The microprocessor system is developed on the basis of the KM1816 BE 51 microprocessor using a DAC. The microprocessor program changes the engine speed in the range from 1000 to 3000 rpm. In microprocessor technology there is an independent class of large integrated circuits (BIS) - single-chip microcomputers (OMEOM), which are designed to "intellectualize" devices for various purposes. The architecture of single-chip microcomputers is the result of the evolution of microprocessors and microprocessor systems, due to the desire to significantly reduce their hardware costs and cost. Typically, these goals are achieved both by increasing the integration of the BIS and by finding a compromise between cost, hardware costs and technical characteristics of the OMEOM. Development of control systems on single-chip microcomputers is one of the most promising areas in the field of process automation, control and management.
