TELECONTROL OF THE EXPERT SYSTEM OF AUTOMATIC TRAFFIC CONTROL: “Актуальные вопросы развития инновационно- информационных технологий на транспорте” АВРИИТТ-2021 I- Республиканская научно-техническая конференция (Ташкент, 24-25 ноября 2021 года) 20 Based on this MS SharePoint program, you will be able to change the organization ’s data into a new template, add additional ones, choose a new design, and take advantage of new features. To achieve this goal, you need to perform the following tasks:  change the site ’s appearance in the Options panel to manually update the theme for themes that are not specific or predefined by your organization.  In earlier versions of SharePoint, site templates were called site projects, but henceforth they are called site templates. The access point “Design Site” is replaced by the access point “Apply Template Site” in the “Settings” panel.  Create site templates to provide reusable lists, themes, layouts, pages, or custom actions so users can quickly create new SharePoint sites with the features they need.  Site templates provided by the organization will appear on the “From your organization ” tab when you select the template type. Installation instructions will depend on the design of the site template. REFERENCES: 1. Guliamova M.K., & Aliev R.M. (2021). Database Concept, Relevance and Expert Systems.

TELECONTROL OF THE EXPERT SYSTEM OF AUTOMATIC TRAFFIC CONTROL Ravshan ALIEV, Professor, Department of Information Systems and Technologies, Tashkent State Transport University, Tashkent, Uzbekistan E-mail: alievravshan7@gmail.com Komoliddin TOSHMETOV, Senior teacher, Tashkent State Transport University, Tashkent, Uzbekistan DOI: https://doi.org/10.47689/978-9943-7818-0-1-pp20-22 Abstract: The article examines the transmission of a tele control and tele- signalization signal in the expert system for automatic control of train traffic, for the detection and control of train data, various types of systems for automatic control of train traffic are presented. Key words: tele control, tele signalization, information, devices, model. “Актуальные вопросы развития инновационно- информационных технологий на транспорте” АВРИИТТ-2021 I- Республиканская научно-техническая конференция (Ташкент, 24-25 ноября 2021 года) 21 MAIN PART Control device for automatic control of train traffic manages the B2 train running behind, by sending a signal (information flow) of the TC tele control to its corresponding device [1]. The tele control signal is obtained as a result of processing the signals (information streams) of the vehicle tele-signaling, which are transmitted to the system control device by the corresponding devices behind the B2 train running and the B1 train in front [2, 3]. In this regard, the generalized information model of the automatic train control system will take the form shown in Fig. 2. Fig. 2. Generalized information model with tele control and tele-signaling After analyzing the obtained generalized information model of automatic control of train traffic to determine the nature and place among other automatic control systems, which can suggest, for example, methods of quantitative mathematical analysis of the system. Expert systems of automatic regulation and control are divided into two classes: open and closed [4, 5]. The latter class is also called closed-loop systems [6, 7]. In open-loop systems, the control device does not receive information about the actual state of the controlled object. In closed systems, the control device receives this information via the feedback line. As you can see, the generalized information model refers to closed-loop automatic control systems. The presence of feedback, according to which the control device receives information about the changing characteristics of the movement of the controlled object, significantly increases the accuracy, noise immunity and safety of the system. From the generalized information model, it can be seen that the characteristics of the movement of the ahead train B1 are measured and transmitted to the control device, i.e. interference compensation method B1 is applied. The expert system evaluates the information and, through the system with feedback and compensation, provides information to the interested services. A feedback and compensation system is called a combined system. “Актуальные вопросы развития инновационно- информационных технологий на транспорте” АВРИИТТ-2021 I- Республиканская научно-техническая конференция (Ташкент, 24-25 ноября 2021 года) 22 In code systems, the value of quantities is encrypted at a certain point in time (time quantization). The quantities themselves can only take certain discrete values (quantization by level), i.e. the system belongs to discrete systems. According to the type of characteristics included in the main relationship connecting the control goal and the characteristics of the control device, controlled device and interference, systems are divided into deterministic and statistical. In deterministic systems, the characteristics are regular and do not contain elements of randomness; in statistical systems, at least one of the characteristics that affects the control goal is random. The presence of random characteristics in the system introduces uncertainty into the control process. In this case, the information about the controlled object available in the control device will always be incomplete, since any maximum information will not unambiguously determine the output characteristics of the controlled object, but will only determine the area of their distribution. Therefore, such systems are called statistical systems with maximum incomplete information about the controlled object. Thus, the analysis showed that the system of automatic control of train movement refers to closed, combined, discrete, statistical. REFERENCES: 1. Aliev R., Aliev M., Tokhirov E., Tashmetov K.

And Restrictions in the way of speed, the development of high-speed traffic. Keywords: high-speed train, Talgo, stage of developing. MAIN PART Passenger trains in the Republic and prospects for introducing high-speed passenger trains on new railways in Uzbekistan at present, the share of rail transport in the Republic of Uzbekistan accounts for about 70% of the total freight turnover of all types of transport and about 60% of passenger turnover [1]. The main stages of the organization of speed and high-speed traffic by terms for the implementation of major activities for the organization of high-speed: High-speed traffic on the railways of Uzbekistan in the mentioned Concept is divided into 4 stages. The first stage (2011 –2015). This is the initial stage related to the preparation and implementation of the high-speed movement of the Talgo-250 Uzbekistan electric train at the polygon of the direction of the Tashkent-Samarkand railroad. Pic. 1. Average operating speed Pic. 2. Uzbekistan in the list of countries with developed high-speed railway infrastructure The second stage (2016-2020). At this stage, the sphere of high-speed traffic expanded at the expense of railroads with mass passenger traffic on the Tashkent-Bukhara section with stops at the Samarkand, Kattakurgan and Navoi stations, high-speed traffic on the Tashkent-Khodjikent commuter traffic direction [2, 3]. “Актуальные вопросы развития инновационно- информационных технологий на транспорте” АВРИИТТ-2021 I- Республиканская научно-техническая конференция (Ташкент, 24-25 ноября 2021 года) 10 The third stage (2021 –2025 years). This stage is characterized by the expansion of the landfill operation area [4, 5, 6] on the management with intensive passenger traffic Tashkent – Karshi with stops at the stations Djizak and Samarkand. At this stage, reconstruction works will be completed with the electrification of the railways in the Marokand-Karshi section [1]. The fourth stage (until 2035). This is the stage of further development of high- speed traffic on the railroad tracks: Tashkent-Navoi-Urgench (Nukus) with stops at Misken, Zarafshon, Navoi, Kattakurgan, Samarkandi Jizak stations. Here, reconstruction (amplification) is required with the electrification of the Navoi-Uchkuduk-Nukus, Misken-Urgench lines [1]. Pic. 3. Share of the population of population by high-speed lines in the general railway structure of Uzbekistan . Pic. 4. Share of high-speed lines in the general railway infrastructure of Uzbekistan . Tashkent – Andijan with stops in Angren, Kokand, Fergana, Andijan and Namangan. At this stage it is supposed: construction (approximately in 2022 – 2030 years) and commissioning of the new electrified railway line Angren – Pap; The formation of the Tashkent – Andijan expressway with the reconstruction (including electrification) of the Fergana railway line Kokand – Andijan – Namangan [2, 3]. It should be noted that the Afrosiyob high-speed train now runs in the direction “Tashkent-Samarkand-Karshi”. The Afrosiyob high-speed train, produced in Spain by Patentes Talgo S.A., overcomes the distance of 344 km in two hours. The maximum speed exceeds 250 km per hour. The total capacity of a comfortable train is 257 people. The electric train consists of 2 head locomotives, 8 passenger cars and 1 dining car. The train provides VIP-class seats, first and economic classes, special conditions for disabled and passengers with disabilities are provided. Pic. 5. Every kilometre of the trip costs passengers € 0.18 “Актуальные вопросы развития инновационно- информационных технологий на транспорте” АВРИИТТ-2021 I- Республиканская научно-техническая конференция (Ташкент, 24-25 ноября 2021 года) 11 In October 2015 JSC “Uzbekistan Temir Yullari” and Parentes Talgo S.A. Signed a contract for the purchase of two high-speed electric trains with a total cost of 38 million euros. It provides for purchase of four head and twenty passenger cars, as well as two dining cars. Two of them are formed, each of them are capable of transporting. Organization of high-speed railway traffic will give an additional impetus to scientific and technical development and improvement of technologies in almost all related industries from mechanical engineering to intelligent computing systems, providing further stimulation of the country ’s scientific, technical and intellectual potential, primarily through placing orders with domestic enterprises to create new models of world-class technology.
