The article presents the relevance of the topic associated with the introduction of technical diagnostics tools and the service system of electronic equipment for AC electric locomotives. Results of operating a microprocessor control system and diagnostics of AC electric locomotives on the Eastern operational area are presented in the form of failure statistics of elements of microprocessor technology. Structure of the technological process of servicing AC electric locomotives on the railways of the Eastern operational area is shown. Authors revealed features of building a system of locomotive maintenance points (LMP), which carry out repair and maintenance of electronic equipment for AC electric locomotives of various series. Functional scheme of the system for servicing electronic equipment for AC electric locomotives has been developed. Bench and technological equipment of the service area for the maintenance of electronic equipment is shown. The article describes development of an automated workplace (AWP) for optimization and repair of a microprocessor control system (MCS) for an electric locomotive, which was not previously in the locomotive sector. Examples of performing technological processes of repairing cassettes of MCS using AWP are given. The following conclusions were made: 1. Statistics of MCS failures and malfunctions of their cells on AC electric locomotives at the Eastern operational area for the period from 2016 to 2018 (LMP of station Tayshet and Karymskaya) shows that the number of failures of MCS decreased by 30 % and the number of malfunctioning MCS cells, received for repair, decreased by 45 %. 2. Automated workplaces created in the JSC “DTsV of the Krasnoyarskaya Railway” for optimizing and repairing the local government of AC electric locomotive made it possible to optimize repairs and create an automated process for the maintenance and repair of electronic equipment for electric locomotives. 3. Developed by specialists of the JSC “DTsV of the Krasnoyarskaya Railway” together with the employees of the LLC “Lokotech-Service” technological model of full service maintenance and repair of electronic equipment for AC electric locomotives on the railways of the Eastern operational area was implemented and well proved itself in the work of the LMP.

Abstract A microprocessor based peanut dryer control system to minimize energy consumption was developed and tested over a 3 year period. Hardware and software needs were described. First year tests were conducted to verify hardware performance. Energy control techniques were proposed and compared with conventional peanut dryer control procedures. In simultaneous comparative tests, the first energy control technique implemented reduced liquified petroleum gas (LPG) consumption 49 percent, electric energy 39 percent and increased time on the dryer 65 percent. Modification of the energy control technique reduced the unacceptable increase in time on the dryer to 10–20 percent while similar reductions in LPG and electric energy were maintained. The improved control technique produced similar results in tests the following year. No losses in peanut quality during drying were observed and the net saving was $5.61 per tonne or a 25 percent reduction in peanut drying costs for Virginia conditions.

The article discusses a method of extreme control of the driving effects of the microclimate, which consists in keeping the objective function at the point of extremum for the control system. To solve the problem of extreme management, it is necessary to introduce computerization of the control and development of forest planting material. This will allow you to collect statistical information for the entire time of observation of plant growth. The primary task here is the analysis of observations and the possibility of generating regulatory influences from the microprocessor control system of the microclimate of the greenhouse. From literature sources, the stages of development of forest seedlings are known, for which data on the natural growth of seedlings and seedlings based on processing of statistical material are obtained. To date, recent studies show that there are no necessary mathematical models, both in growth and in the development of planting material under changing conditions and the nature of growth, and in time periods. Thus, objects of sheltered soil can be attributed from the point of view of the object of control and regulation to systems with variable parameters. That is, they can be characterized as unknown mathematical models.
