USE OF VIBRATION SENSOR AS DETECTION OF RAILWAY IN MECHANICAL SIGNALING SYSTEMS

Abstract

Interlocking equipment used to secure a system. One of the systems on mechanical signaling
that is contained in trains. Mechanical signaling is used to form, lock, and control so that the
system is safe from errors that occur in the system. In the world of railroad signaling
mechanically it is very much needed so that the train route remains on the correct and safe
lane. The railroad to be traversed by the train is carried out mechanically. The development
of electronic technology can have an impact on railroad signaling. So that the application of
electronic technology can be done on railroad signaling in Indonesia. Rail contact,
mechanical is signaling that is used to detect the presence of trains. Equipment rail contacts,
to detect the presence of facilities on the railway line at the emplacement. The way rail
contacts work uses an iron lever that is in direct contact with the rail wheels so that the
movement of the lever causes the switch in the device to be active. Levers that are often
stepped on by the train's wheels cause wear. A worn lever causes the level of precision to
weaken, making it unsafe for trains to be on the right track. The application of electronic
technology, a microcontroller, can replace the worn lever. The SW-420 sensor as a vibration
detector is integrated with a microcontroller to determine the presence of a train. This sensor
can be applied as a train detector by utilizing vibrations on the rails. From the results of trials
conducted, the system with sensors that are built can detect rail vibrations when the railroad
403
stepped on the rail. So that train movement can be detected, and the microcontroller can show
the vibration value data in realtime.
