Microprocessor semi-automatic blocking (MP PAB) is a system for interval control of train movement.
Designed for:
- Monitoring the condition of rail lines;
- Transfer of information between stations;
- Control of traffic lights according to traffic safety conditions;
- Formation of signals for automatic locomotive signaling systems;
- Transmitting data on the train position on the stretch to the station;
- Diagnostics of equipment for semi-automatic blocking signal points.
MP PUB allows you to increase the capacity of sections with the required traffic safety.
The system is designed for:
- Single-track sections of railways equipped with direct or alternating current electric traction systems, as well as autonomous types of traction;
- Areas with centralized power supply for passenger cars;
- Modernized lines.
The system equipment is located centrally at EC station posts that limit the stage, as well as at the stage in track and transformer boxes.
Advantages of the MP PAB system
Increased operational reliability due to:
- Redundancy of main system components;
- Application of a more reliable element base;
Reducing the number of system elements, including signal cable consumption.
Increasing availability factor due to:
- Possibility of reconfiguring the system in the event of failure of its individual components and sensors;
- Construction of a redundant power supply system.
Improving the safety of train traffic on the stretch due to:
- Using additional coding of signals in track circuits in order to eliminate mutual influence;
- Using the logic of a train following a section;
- Possibility of influence on distillation devices (turning on prohibiting indications at traffic lights, etc.) by the station duty officer or dispatcher for the purpose of fencing off the work area, etc.
Reducing capital and operating costs due to:
- The use of a small number of unified blocks on plug connectors with a minimum number of interblock connections;
- Reducing the dimensions of devices by 3 times;
- Reducing the consumption of signal-blocking cable by 30 – 50%;
- Possibility of automated measurement of system parameters with maintenance of an electronic log of measurements by the duty engineer of the signaling and communications distance.
