Transcripción del abstract original del autor: The monitoring system for the exposed gas pipeline was developed to guarantee the safety of exposed gas pipeline. Recently, many kinds of underground constructions are in progress such as the underground passage and subway station in surroundings of high pressure gas pipeline. The range of exposed gas pipeline arising from the construction is about 50 to 300 meters. If the exposed gas pipeline is destroyed by the failure of supporting structures, there is a possibility that large scale gas leakages can be occurred, which result an enormous social damage. If the large scale accidents take place, it will be very difficult to manage the emergency. The exposed gas pipeline monitoring system is accident preventing systems which forecast and manage an emergency before the accident occur. The monitoring system for the exposed gas pipeline consists of image, vibration (acceleration) and strain (stress) processing. This system uses a Windows running host PC separated remotely, and is controlled through an ethernet connection. Also, the software manages vibration tendency and history of data for exposed gas pipeline of the construction region.
