Microprocessor interlocking system MPC-MISAT

Microprocessor interlocking MIS-MISAT is designed for centralized traffic control in railway stations and on the implementation of their remote control by arrows, signals and other objects, train safety by mutual circuit switches and signals and automatically controlling the movement of trains, the actions of station dispatcher (operator ), the state of devices of railway automation and writting an events archive ("black box");

MIS is intended for the design of new and reconstruction of existing electric interloking (EI) all stations.

Implementation of MIS allows to extend the functionality of relay systems EI in providing the required degree of safety and reliability.

Compared to the relay interlocking of the system through the use of the MIS microprocessor technology offers several new features:

automatic logging of personnel action, the system and devices (function "black box");
archiving and database maintenance for the formation of various certificates and reports on the work performed;
archiving, viewing and statistical processing of information about failures in the devices of EI;
diagnostics system MIS;
control and archiving of current in motor control circuits of an electric switch;
monitoring and archiving of the lamp voltage of rail traffic lights;
control and archiving of the voltages of the supply panels;
prompt submission of reference data and data of technical and administrative act of the station;
automation of management by forming routing tasks for the coming period;
support for operational staff in non-staff situations (with the exception of incorrect action mode prompt);
the possibility of withdrawal of the monitors AWS additional information;
conducting technical diagnostics and monitoring devices pre-failure states;
EI pairing with a top-level automation, ensuring coordination with the system of supervisory control and remote supervisory control, alarm of railroad workers systems, etc.

The system MIS most of the functions of recruitment and setting of routes are implemented on the basis of small-sized highly reliable micro-processor hardware, in comparison with relay systems allows considerable, but reduce the number of failures by reducing the number of relays and reduce the area of the premises relay.

All interlocking implemented on the basis of microprocessor equipment.

MIS is equipped with means of internal (self) diagnosis, which allows you to manifest "failure to warn" state or failure of components the MIS. Upon detection of a system failure causes MIS outputs object controllers and circuits connected to them in a safe condition.

Outdoor equipment MIS includes standard signaling device (arrows, railway lights, level crossing equipment, etc..).

System MIS-MISAT provides dual control arrows control arrows cleaning, brake control stops, guard convoys on the roads, warning rairoad workers, linking systems HCPS (highway crossing protection system), ASS (automatic switching system) and all types of ABSS (automatic block signal system).

MIS is a modern alternative to the railways operated relay system of EI, provides a significant increase in safety and reliability of traffic control at railway stations.

MIS-MISAT can be used without cascading to build plants with capacity:

The number of switches to …………............... 256 pcs;
The number of rail traffic lights to ………...... 512 pcs;

MIS-MISAT is not inferior in performance to any known analogs, and many of the parameters exceeds them.

Features of the MIS:

completely non-contact interface with actuators without relay. All interlocking of program implemented in the master controller;
protected against switching and lightning surges;
MIS has a high level of safety that meets the requirements of the standard of Ukraine DSTU 4178, and the requirements of international standard IEC 62425 (SIL level 4);
integrated in the control system of the MIS nearby running lines, crossings and other objects RAT;

The MIS-MISAT system consists of the:

cabinets of control with microprocessor system equipment;
input modules;
outnput modules;
item’s controllers;
CCS’s controllers;
TRC’s controllers;
power supply modules;
two bundles of the control system of the MIS;
server TDS;
workstation SDO;
workstation MIS-Stuff;
rack power;
relay circuits linking with the relay system RAT;
cross equipment with the elements of lightning protection;
outdoor signaling devices.

Information about the state of the objects come from the input modules, track receivers mall, object controllers, switches and traffic lights on the link in the CAN MIS bundles dependency and to the server TDS.

Commands are sent on the same link from the bundles to the object dependencies MIS switches and traffic controllers, controller CCS, as well as to the output modules, providing switching relay circuits linking.

Bundles of dependency analysis is carried out MIS commands coming from the workstation SDO, in the case of compliance with safety messages on the command generates object controllers, and the opening of the respective outputs of the output modules.

Server TDS collects data from objects of control, analyzes the correct operation of the MIS as a whole, maintains control of the optimal parameters controlled by the currents and voltages, the parameters of the transfer of information along the lines of communications, and maintains an archive of all the conditions and parameters of state control objects. Based on available data defines pre-failure device status signaling and generates the appropriate messages to the staff. The computer also provides an archive at any time, and settings for all the states of control objects.

MIS structure consists of three levels:

Custom Level. At this level, there is an interaction with the operating nym and support staff, the exchange of data with top-level automation. Here are located:

workplace SDO. In the workplace station duty officer (SDO) include: Automated Workstation (AWS) SDO (industrial computers, two widescreen monitors, the manipulator "mouse" and a keyboard), a special computer desk, chair;
workplace AWS MIS-Stuff. The workstation includes electromechanical signaling: AWS MIS-Stuff (industrial computers, two widescreen monitors, manipulyator "mouse", a keyboard), a special computer desk, chair;

The level of computing and dependencies. At this level there is the collection, analysis, processing, issuing control commands and data archiving, came from the I/O modules, object controllers arrows traffic controller CCS (continuous cab signalling), computer user level. Processing is performed on the relationships defined at the design stage of EI. At this level are placed:

two interlocking bundles, each dependency set consists of 2 controllers dependencies centralization MK-Z.MPC - 1- and 2-nd channels. This structure placement controllers needed to implement the structure of work "2 to 2", which means:

at a time can manipulate objects MIS only one set of dependencies, operating on a "2 of 2". Work set on a "2 of 2" has the added benefit in terms of security;
2nd set of working in the "hot" re-reserves with respect to the first set of the scheme "2 of 2", but without MIS facility management;

Safe switching module communication lines interlocking bundles MK-SSW.CAN. The module is designed for safe switching instruction stream on the object controllers (flow direction - "object in the controllers") between the sets of dependencies. Module MK-SSW.CAN also reserved another module MK-SSW.CAN (in "hot" standby).
