Abstract

Conventional signaling system consist of signal, point machine, train detection and interlocking. Generally, implemented interlocking system in Indonesia are relay , programmable logic controller (PLC) and computer based types. Whereas, the conventional train detection system uses axle counter or track circuit. The problems of conventional train detection are its installation depends on the rail, so it is risky to rise a damage when there is track maintenance or derailment. In addition, the cost is relatively expensive and it is no easy to maintenance.
To address the problem, PLC based signaling system using infrared based train detection system is proposed. The system consist of infrared sensors that install on a block and integrate with the PLC to controltrian operation route on single track automatically.
The system are supposed to solve the installation problem, easy to maintenance and relatively competitive cost.
