The main functions of the control system for technological discipline of the train control process are:

- in the control and operational impact on the train position in sections and on the road as a whole based on information received from locomotives and external automated and information management and information systems about the arrival, departure and investigation of trains for decision-making;

- in the introduction of each of the trains according to the energy-optimal schedule, which entails an increase in technical speed, throughput, a decrease in the downtime of locomotives, wagons, etc .;

- in a forced stop of the train in the service braking mode in the event of an emergency;

- in the control of technical means and technological processes during the movement of trains.

Traffic control is carried out by train dispatchers of the road traffic control center. Dispatchers manage the transportation process based on information received from stations and directly from drivers (via radio), as well as using data from automatic systems. Thus, along with the safety management circuit, a technological circuit is created, which, due to the control of technological discipline and the operational interaction of the employees of the road transportation control center with the locomotive, increases the management efficiency and further increases the level of safety.

Direct control of the movement of the train is carried out by the locomotive driver (traction rolling stock), the interaction with which (information exchange) occurs through the following means:

- outdoor traffic lights, fencing signals, signal indicators and signs;

- manual signals given by road workers (station duty officers, rolling stock inspectors, trackmen, level duty officers, etc.) with the help of flags, lanterns, disks or hands;

- sound signals (whistles, sound horns, firecrackers, etc.);

- signals of automatic signaling;

- automatic train braking control system (SAUT);

- automatic identification of rolling stock (AIS "Palma");

- Television surveillance systems for rolling stock, and other train control systems.

- voice radio communication, through which the driver receives the information necessary for the train.

An integrated locomotive safety device provides the determination of coordinates from satellite navigation devices, angle sensors, inertial measuring unit and electronic map of the site. These data are received in a complex locomotive safety device via an inter-circuit communication system (gateway), in which the coordination of information flows.

An inertial measuring unit measures 3 linear and 3 rotational accelerations along the X, Y, Z axes. These data are used both to increase the accuracy and quality of the navigation system and at the same time the dynamic characteristics of the locomotive such as vertical and lateral accelerations, locomotive buildup are calculated. This data, together with the information of the integrated locomotive safety device, is transmitted via communication channels to the database for operational processing and detection of locomotive behavior anomalies.

Traction rolling stock control and train management as a whole is carried out using on-board instruments and control systems, ensuring safety, navigation, measuring, diagnosing and issuing recommendations for optimal train movement.

The drawing shows a functional diagram of a system to ensure the technological discipline of supervisory control of train traffic.

The functioning of the system is as follows.

The main safety device on the locomotive is a comprehensive locomotive safety device 14, interacting with the system via digital communication channels, through which the code signals of automatic locomotive signaling (ALS of various modifications) are received. Digital communication with the integrated locomotive safety device 14 is carried out through a special ground control computer complex 7, which provides two-way communication of the traction rolling stock 8 with the central processing complex 2. The control computer complex 7 also receives data from the onboard control systems 11, from the measuring inertial block 13, which are installed on the locomotive, with technical means 10 of railway automation and telemechanics. The feedback signal to the traction rolling stock 8 is sent after processing and reconciliation of those arriving at the central processing complex 2 with the initial data 9 for managing railway transport, arriving at the central processing complex 2 from the automatic system 6 for managing railway transport. Based on the received data from the central processing complex 2, the integrated locomotive safety device 14 provides, through wired communication with the on-board control systems 11, the formation of the value of the permissible speed of the traction rolling stock 8 or its stop. This is the first circuit - the security circuit.

The second circuit is the technological interaction with the traction rolling stock 8. The interaction occurs through devices that are not directly safety devices, i.e. through on-board control systems 11, which may include: automatic train braking control system (SAUT), automatic train driving system (USAWP), microprocessor-based locomotive control system (MSUL) or other control systems. From the on-board control systems 11, the digital interaction unit 12 transmits data from the locomotive to the automatic railway control system 6. The automatic control system 6 of the railway transport in the memory unit 9 contains the source data for the management of railway transport and receives, also, current data from the technical means 10 of railway automation and telemechanics. After processing and comparing the data of the on-board control systems 11 and the data of the technical means 10 of the railway automation and telemechanics with the initial data for the management of the railway transport, the automatic railway control system 6 transmits a signal to the central processing complex 2.

The data entering the central processing complex 2 from the control computer complex 7 and the automated system 6 for managing railway transport is processed and analyzed. Based on the analysis of data in the central processing complex 2, information solutions are generated that are confirmed or denied by means of workstations 5, which are transmitted along the primary circuit of the system via digital radio communication to the on-board control systems 11, (SAUT system) of the locomotive acting as an element that receives and processing information from the central processing complex, thereby increasing the safety of railway traffic

The combination of the central processing complex 2 and the automated workplaces 5 (according to the number of workplaces of the operational personnel of the dispatch center of transportation control) implements the functions of controlling technological discipline at the level of the dispatch center 1 and works as an operational decision support system.

All the system’s work is displayed in the form of reporting forms, on the web portal 4 of the system operating on the basis of server 3. Web portal 4 performs the task of analyzing the actions of the operational personnel of dispatch centers, stations, etc. (information coming from workstations 5), the correct functioning of the technical means 10 of railway automation and telemechanics and locomotive equipment, etc. At the same time, the web portal 4 can issue recommendations based on a comprehensive analysis of interrelated events. For example, from the analysis of the frequent delays in the signals of the input traffic lights, a solution follows, which together carries recommendations on laying additional paths along the main course, preparedness of the infrastructure, etc.

Confirmed decisions that require a direct impact on the locomotive are transmitted over the public data network through the control computer complex 7. In addition, through the TDP data transmission unit and TETRA standard digital radio communication at a frequency of 460 MHz, it is also transmitted to the locomotive equipment of the SAUT system acting in as an element that perceives and processes information from the central processing complex.

The introduction of a system of primary control to ensure the technological discipline of dispatch control of the movement of the measuring inertial unit, with its installation on a locomotive, can improve the quality of dispatch control of the transportation process by detailing the data of the radio exchange of stationary systems with on-board control systems and safety systems of traction rolling stock.
