Solid State Block Proving By Axle Counter (digital)

Solid State Block Proving by Axle Counter (digital) is a solid-state system used for controlling the coordinated movement of the train in the block section working on absolute block working principle. The system has been developed as per rdsospn1752005 both for single line working and double line working.
Features:
The system incorporates auto features and eliminates manual co-operations from other end for line clear and line close operations. Emergency cancellation at the receiving station. Automatic train on line. Automatic line close after sequence proved at receiving end and section is free. Simplified block back block forward operations. Cooperative cancellation. Line clear block key (LCB key) to prevent automatic granting of line clear. Station master key (SM key) to prevent unauthorized panel operations. Fully solid state and relays are only for final vital outputs. Event logging operations and data storage in built in the system.
Advantages:
Less maintenance and requires no periodical overhauling in consideration with the electromechanical systems. It considers signal overlap distance for granting line clear, which is not available in some of the present systems. It has inbuilt data logging capability which logs all the panel operations, events, relays status and other information. All the panel indications are with LEDS. No need for next train on place after push back operation.
