The system includes all the functions of traditional centralized traffic control systems, as well as the new functions based on the informational technologies, which is determined for relay and microprocessor automation device implementation at the stations and spans.
Microprocessor centralized traffic control belongs to informating-controlling automatic control systems of discrete-continuous technological processes with high informational capacity level and functional reliability.
The basic objectives of system designing are:
- Advancement of technical and economic indices of vehicular process control efficiency;
- Reduction of operational costs due to decreasing of assistant station-master numbers;
- Advancement of labour productivity of assistant station-master, increasing of dispatching section extentions;
- Improvement of working conditions of dispatching and operational dispatching staff.
Microprocessor centralized traffic control is used for:
- Organization of centralized monitoring and/or control at a section where the working place of dispatcher devices is organized, transferred or modernized;
- Control over the neighboring stations with a support;
- Organization of regional and/or road centralized traffic control centers with a connection of dispatcher device working places into an informational network;
- Information transmission about the state of dispersed control and monitoring objects to the higher and adjoining systems in the real time scale.
Functions executed by Microprocessor centralized traffic control
Dialog functions:
- Information representing and cooperation of the dispatcher device with Microprocessor centralized traffic control system on a section;
- Microprocessor centralized traffic control cooperation of neighbouring ranges (sections, junctions, large sorting, divisional and passenger stations);
- Cooperation with other informational and control systems (telemechanics, energy saving, automatic system of transport control and organization and etc.).
Executive train situation monitoring on a section, modeling and prediction train schedule:
- Visualization of information about train situation, states and working modes of signaling, centralization and blocking means, fulfilled schedule and indexes of dispatcher’s work in a user friendly form;
- Representing to dispatcher information and reference and signaling data, which is required for making decisions on vehicular process control;
- Train location model input;
- Analysis and prediction of train schedule;
- Analysis and prediction car movements.
Task recording:
- Control action of dispatcher device fixation;
- Train situation fixation;
- Malfunctions of microprocessor centralized control devices fixation;
- Fixation of operational check results and system diagnosis of prime load and at system restoration after malfunctions;
- Accumulation and creating of archives about traffic with the possible access.
Self-diagnosis and diagnosis of systems of railroad automatics and telemechanics:
- Sustaining of reliability parameters of microprocessor centralized traffic control technical devices at a determined level;
- Sustaining of authenticity parameters of information at a determined level;
- Time reducing for elimination of malfunctions.
State control and monitoring of system objects of railroad automatics and telemechanics:
- Telesignalization;
- Telecontrol;
- Automatic control of system devices of railroad automatics and telemechanics (together with other subsystems).
