摘要
为了解决超长输水隧洞安全监测工程数据传输距离远以及因安装不同类型传感器导致监测数据格式多样的问题,在对水利工程安全监测系统常用数据传输方式进行优劣比较的基础上,提出适用于光纤传感器和常规传感器交叉组合监测的GPRS数据传输方式,探讨其在超长输水隧洞工程监测信息传输中的适用性和可行性,并在西南某超长输水隧洞工程中进行应用验证。根据超长输水隧洞工程通常无交流电供电的特点,提出风光电互补供电的方式,能够满足监测系统长期供电需求。
In this study it is introduced the general packet radio service( GPRS) information communication method, which combining fiber sensors and common sensors, for the long transmission distance of safety monitoring engineering data in super long distance water delivery tunnel and different data formats(resulted from multiple sensors). And it is compared with the common information communication methods about safety monitoring system in hydraulic engineering practice. Besides, it is discussed the applicability and feasibility of the information communication method for super long distance water delivery tunnel as well as tested in an engineering practice in the Southwest China. Due to the fact that alternating current is not available for outdoor projects of super long distance water delivery tunnel, it is proposed the power supply mode of solar, wind, and electrical energy, which are able to meet the power supply demand of monitoring system for a long time.
