无线传感网络于地下结构环控防灾监测应用研究

本研究针对在台湾已完成的个案子予以整理研讨,说明WSN应用在环控防灾监测上的具体方案。其中包括隧道环控与边坡坡面倾度监测,其成效显着,数据稳定。基于上述稳定的成果,建议WSN系统应用于地下结构物监控,例如地铁隧道。至今地铁定期都会有养护人员到地下结构体里进行目视检查,但此方法无法达到实时、有效、全面性的控制。当地下信道结构产生变化,未能实时掌握了解,并立即进场修复,而造成结构严重之损坏。导致难以修复,甚至需改线重建。本研究另拟于上海同济大学的地下通道作为示范应用地点。对于隧道断面变形,藉由倾度计并运用WSN系统间接量测。不只监测振动频率,包括裂缝的开裂以及渗水也必须纳入考虑。此外,配合固接式Wi-Max传输/储存,布置一套实时环控监测系统,达到实时量测感知、防灾之目的。

Study of Underground Structure Environmental Control and Hazard Mitigation Monitoring by Using Wireless Sensor Network (WSN)

In this study,WSN applications in environmental control and hazard mitigation monitoring which completed in Taiwan are organized.The effectiveness of these applications,including monitoring on tunnel environmental control and slope inclination are significant.Based on the satisfied result,the WSN system is suggested to be used in the underground structures,such as the subway tunnels.Since the subway on a regular basis will have a visual inspection by maintenance personnel to the underground structure,but this method can not achieve real timing,effective and comprehensive control.If the structure changes not readily grasp the understanding and approach to repair immediately,resulting in the severe damage of the structure makes it difficult to repair,or even need to line change and reconstruction.In this study,the underground passageway of the Tongji University in Shanghai is also proposed as a demonstration application site.Concerning the deformation of the tunnel cross section,indirect measurement by tilt meter on the segment will be used by WSN system.Not only vibration frequency to be monitored,but also fissures movement and seepage water are also need to be taken care.In addition,with the fixed Wi-Max communication station and storage to the perception of real-time measurements,and the purpose of hazard mitigation is to be achieved.
