Freeboard Monitoring System as an Early Warning System on Railroad Bridge with Solar Cell as Resource Energy

摘要

The bridge is a construction that connects paths that are cut off by rivers, ravines, or construction. One of the requirements of the bridge is freeboard. Safety height is the height measured from the water to the lowest bridge construction. The survey results are still a railroad bridge that does not meet the requirements for security, which is below one meter. The absence of continuous, direct monitoring can cause disruption of travel until an accident can occur when a major flood occurs. The pattern of river water level changes often changes the monitoring of bridges that have the potential for flooding. From the above problems found an alternative solution to the problem, namely using a water level monitoring device that can monitor the water level continuously. The tool will send the results in the form of water level data and provide an early warning when the water level is approaching the bridge or has a dramatic increase in height.
