Production

Microcontrollers in combination with computers make the system more reliable, convenient and simple for maintenance at cost decreasing comparing to the relay systems.

Relay and processor interelocking system fulfils the following functions:

• Technological object control at a station (the basic functions of power interlocking on switch and signal centralizing);
• Monitoring the state of control and inspection objects at a station;
• Providing the train traffic security;
• Diagnosis;
• Cooperation with operator;
• Connection with other systems of automatic control;
• Making archives about the state of control and monitoring objects, activities of an operator, data about diagnostics of composite systems.

Regular control functions:

• Route setting of any complexity, length and category;
• Route cancellation (as preliminary as well as closed route);
• Emergency route release;
• Individual switch control;
• Locking/unlocking of switches;
• Opening of call-on signal;
• Route shifting of switches;
• Automation of assistant station-master actions during shunting operations;
• Tracks protection;
• Auxiliary switch shifting (with the button VKS);
• Switch drive disconnection;
• Alarming when malfunction occurs;
• Switch staging at a model.

Diagnosis:

• State monitoring technical device and objects of control;
• Monitoring of malfunction occurring and transition of separate devices into safe mode;
• State monitoring of power supply devices.

Monitoring and representing:

• Current control monitoring of control objects;
• Monitoring of route setting propriety;
• Monitoring of assistant station-master actions, especially when interlocking and blocking system devices are partially or fully switched off;
• Representing of stationary gridiron;
• Current state representing of control objects;
• Assistant station-master action representing on display.

Additional:

• Running of the message records for the whole day with marking of date and time of events with regard to:
  a) Stateof the control and monitoring objects;
  b) Turning on and off of automatic working place;
  c) Commands of control, which were input;
  d) diagnostic system information;
• Creating archives for the last 31 days;
• Possibility of coordination with informational systems of the higher level.
