ARM EC

ARM EC – a solution for partial modernization of electric interlocking systems, in which a computing complex performs interlocking functions integrated with input/output controllers. Similar to relay-processor interlocking systems, applied software and hardware complex allows replacement of control panels of relay interlocking systems to modern ARM DSP terminals at minimum cost. Replacement of only control panel is also a viable option, leaving interlocking control circuit as it is.

ARM EC pieces together all advantages of classic interlocking systems and modern computer-based control systems, such as cost-efficiency, high reliability, simplicity of maintenance, convenient work places, capability to log events and view archive, remote station control, flexibility and promptness of correction of software project in case track layout of a station changes, etc.

This solution is applicable to existing stations of any size, when already installed electric relay interlocking systems have not depleted their operating resource yet or construction of new stations with a minor quantity of points.

Application

  • Partial modernization of relay interlocking systems at minimal costs.
  • Construction of new interlocking posts featuring control via ARM DSP Terminal.
  • Organizing of remote control over already existing stations. 

Advantages

  • System is based on general industrial components.
  • Creation of ARM EC software project is performed via MPC-I CAD via visual programming, oriented at users qualified as railway signaling engineers. Project development is identical to project development of interlocking systems. Project is created in the relay circuit editor. MPC-I CAD represents standard circuit nodes that perform interlocking functions, as standard units, which the user can allocate on a drawing and connect between each other in correspondence with geographical allocation of facilities on the station layout.
  • Increased train traffic safety, throughput and capacity of a station, improved route building capability.
  • Cost efficient solution, optimization of running costs for maintenance of relay equipment.

Digital Interface

MPC-I with digital interface for control over trackside objects (points and light signals) uses object controller system. It converts logical information exchanged with UKC controller, into physical information in correspondence with configuration of the interlocked station object. In case object controller system is used with MPC-I, one more redundant UKC cabinet is included into the system. Quantity of controlled objects is expanded by increasing the number of object controller cabinets.

Specialized communication object controllers carry out interaction of object controller system with UKC Cabinet via secure protocol. Point object controllers are designed for monitoring and control of point drives of direct current (110-230V), alternate single phase (220/230V), alternate triple phase (3x220 – 3x400V) current featuring two-/three-/four-/five-/seven-/nine-wire communication lines (nine-wire circuit is used for non-contact sensors).

Each light signal object controller capable of controlling 8 channels of light signal systems (distributed between 1-4 light signals) featuring monitoring of “filament” state (both in enabled and disabled state of a controlled object). Separate filaments of lamp light signals and LED-heads of standard light signals can be used as light signal systems. 

Application

  • Optimization of running costs due to reliability of the system and application of self-diagnostic systems.
  • Increasing train traffic safety.
  • Replacement of outdated relay interlocking systems.
  • Promoting a better work ethics and productivity among operating personnel.
  • Event logging, archiving and data base building of operating personnel actions and operation of station devices.

UKC Hot Standby

Hot standby is used for increasing reliability of UKC operation and is based on “two out of two + two out of two” principle. Each UKC implements diagnostics of degradation level, which uses current or newly input diagnostic information to determine presence of failures and/or errors of interlocking controller hardware and integrated subsystems.

Each running cycle information on interlocking controller degradation level is transferred to the paired controller via cross communication channels.

Only one UKC with the lowest degradation level is working at a time, being an “active” set. Deactivated UKC, being “passive” has no effect on operation of the system.

Activation or deactivation of sets is based on the following data:

  • In case degradation level of an active UKc is higher than that of a passive UKC for two or more hot standby cycles;
  • An operator issued a command for manual UKC activation (using ARM DSP or ARM ShN). UKC swapping time does not exceed 200-500 ms.

Swapping between active and passive UKC sets does not interfere with technological process of a station.

Remote control, multistation mode

Remote control from a single post is used in low-traffic section to optimize the numbers of operating personnel, as well as on sections that require seasonal work of a station master on separate stations. Each station is fitted with MPC-I equipment set both with relay and non-relay interface.

  • division of large-scale stations on unlimited number of zones for control (secular and seasonal);
  • selection of sections for temporary local control (both with arrangement of additional working place and with control from point tower) on the station with shunting works;
  • integration of low-density stations into joint control tower without using facilities of CTC tower and without installation of linear CTC post. Herewith, possibility of local control and monitoring still remains;
  • arrangement of multi-level hierarchical control systems as zone-station-section-railroad with possibility of prompt transmission of control to the relevant level if necessary.

Multistation mode allows decentralized equipment allocation on large stations, control adjacent stations without organizing control posts on them.

In multistation mode only one MPC-I central processor (redundant UKC with ShTK), located on principal (sectional, zonal or major intermediary) station simultaneously interacts with object controllers of several adjacent railway junctions, passings and minor intermediary stations, premised on criteria of full CPU load.

Multistation mode allows for significant reduction of costs for comprehensive fitting of a railway section.

MPC-I CAD Software

MPC-I CAD computer-aided designing system is created to assist designers and customers of MPC-I system.

Thanks to CAD, the labor intensity of designing is significantly reduced, and the customer’s personnel with appropriate authorization can independently and promptly make corrections into MPC-I software in case track layout of a station changes. Moreover, CAD software helps reducing influence of the human factor.

Operating organizations are offered to variants for system reconfiguration – using design capabilities of JSC R&D Company Promelectronica or independent adaptaion within the changed part of the existing design with the help of MPC-I CAD and in cooperation with the Service Center of R&D Company Promelectronica.

SPPR Decisionmaking Aid System

SPPR Decisionmaking Aid System is an informational system that provides station master with additional information on current state of signaling equipment, errors in their operation, procedures during emergencies and other possible situations. Decisionmaking Aid System decreases the influence of the human factor on MPC-I operation and possible operation errors both under normal conditions and under conditions of device malfunction.

The system automatically detects:

  • loss of point position control;
  • tripping of train derailment detection system;
  • tripping of fire alarm system;
  • cyber security breach event, etc.

SPPR Decisionmaking Aid System can be integrated with MPC-I. SPPR provides recommendations on further actions in the form of a checklist with a capability of marking the fulfillment. Information from the system is displayed on an additional touch screen monitor.

  • The following documents were used during development of SSPR System:
    “Rules for technical operation of railways in the Russian Federation”, approved by order of the Ministry of Transportation of Russia of 23 June 2022 No.250 (hereinafter PTE), including “Instruction for signaling on railway transport of the Russian Federation” (Annex 1 to PTE) and “Instruction for organization of train traffic and shunting operations on railway transport of the Russian Federation” (Annex 2 to PTE).
  • Instruction for ensuring train traffic safety during operation of signaling devices and system TsSh-530-1, approved by decision of JSC Russian Railways No.2055r.
  • Instruction “On operation of signaling equipment on stations”.
  • Technical and executive directive of the station.
