With the ever expanding urban areas, existing railways often carry hazardous materials very close to urban areas. Train derailments, the added danger of hazardous material contaminants, and the risk of explosions can be very costly to society and fragile ecosystems, and may cause irreversible damage to the environment and aquatic life. Faulty railcar wheel carriages also greatly contribute to noise pollution in densely populated urban areas. Existing methods of wayside railcar wheel impact sensing are complicated and expensive to install and requires regular maintenance and calibration. Seismic rail impact sensing are proving to yield much higher accuracy at substantially lower installation and maintenance cost. It finally provides a low cost inspection solution to scan railcar wheels for compliance in order to mitigate the risk of environmental damage caused by derailments. Seismic wheel sensing works on the principle of seismic wave phase analysis, the sensors do not have to be installed on the rail track but can be installed within a convenient distance parallel to the track. The system can be installed as a permanent installation or through mobile deployable stations. These sensor stations can then be deployed strategically across major rail arteries. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Seismic rail sensing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
