The article describes the modern problem of automatic flame control of industrial installations. The research of this problem is usually begun with the analysis of emergency mode of thermal generating units, divergence of parameters burning processes from accepted value. The most unfavorable factor for trouble-free operation of industrial thermal plants is the cyclical nature of the load changes energy-consuming devices with deep and rapid changes. The paper presents a study of physical factors affecting the stability of combustion in furnaces, the violation of which leads to abnormal flameout. It helps to equip thermal units with effective automatic protection

Automation of productions is a necessary condition of reduction of losses for processing enterprises. Any automated system contains subsystems, each of which solves specific objectives, being at the same time accessory of all system. Therefore, when starting designing a system of acceptance and processing of raw materials, it is necessary to define the importance of result of the solution of each task for increase in efficiency of a production cycle. In the article we present results of expert polls of experts – wine makers for definition of problems of automation of processes in the plants of primary winemaking

The work is devoted to the topical issue of increasing the productivity of computers. It has an experimental character. Therefore, the description of a number of the carried-out tests and the analysis of their results is offered. Previously basic characteristics of modules of the computer for the regular mode of functioning are provided in the article. Further the technique of regulating their parameters in the course of experiment is described. Thus the special attention is paid to observing the necessary thermal mode in order to avoid an undesirable overheat of the central processor. Also, operability of system in the conditions of the increased energy consumption is checked. The most responsible moment thus is regulating the central processor. As a result of the test its optimum tension, frequency and delays of data reading from memory are found. The analysis of stability of characteristics of the RAM, in particular, a condition of its tires in the course of experiment is made. As the executed tests took place within the standard range of characteristics of modules, and, therefore, the margin of safety put in the computer and capacity of system wasn't used, further experiments were made at extreme dispersal in the conditions of air cooling. The received results are also given in the offered article

The article tells about the conception of creating program training complex and the results of its working

The article is devoted to ensuring safe operation of industrial thermal aggregates of low power. The problem of ensuring trouble-free operation of power stations on the channel of control of a flame is considered. The main attention is paid to the requirement of speed of control of a flame. The reasonable method of calculation of the lower temporary parameter of operation of system of automatic protection on the researched channel is for this purpose given. At the same time, parameters of fuel-air mix of gases in furnace amount, design features of the furnace aggregate, thermal losses which accompany explosion in a fire chamber of the power station are considered

Currently, the problem of using a "client-server" technology for database is up-to-date. Among its advantages it has a high degree of security, the ability to work with multimedia and non-standard data, simple tastes to the hardware power client stations, the territorial independence of work in both local and wide area networks. The article presents the concept and describes the implementation of a client-server information system configuration databases based on plug-ins that enable flexible, fast and efficient to make changes to an existing application for working with databases. This approach solves the problem of using one program to connect to multiple databases
