摘要
目前地质灾害隐患点的公网信号覆盖不全面、不稳定,使地灾监测设备在线率较低。通过研究在地质灾害频发和通信覆盖较差地区,采用无线专网技术,在四川开展地质灾害监测设备数据传输与调度指挥系统小规模试点工作。无线专网可在高山峡谷地区实现比公网通信更远、更稳定的覆盖,且通过无线自组网技术可以实现多跳传输,保障在灾害条件下系统传输和应急指挥的可靠性。研究成果可为后续开展更大规模的地质灾害监测专网建设提供参考。
Currently,the public network signal coverage of geologic disaster sites is not comprehensive and stable,which makes the online rate of geologic disaster monitoring equipment low.Through the study,a small-scale pilot work of data transmission and dis⁃patching command system for geohazard monitoring equipment is carried out in Sichuan by adopting wireless private network technolo⁃gy in geohazard-frequent and poor communication coverage areas.Wireless private network can realize more far and stable coverage than public network communication in high mountain valley area,and can realize multi-hop transmission by wireless self-organized network technology,which can guarantee the reliability of system transmission and emergency command under disaster conditions.The research results can provide reference for the subsequent construction of larger-scale geologic disaster monitoring network.
