Abstract

The invention discloses a real-time monitoring and early warning system for geological disasters, which comprises a system monitoring subsystem, a data center subsystem, a prewarning subsystem and a communication network, wherein, the system monitoring subsystem comprises at least one monitoring station and at least one continuous operation reference station and is used for acquiring observation data of the monitoring stations and continuous operation reference stations and the data of the periphery of the stations; the data center subsystem is used for receiving the observation data of the monitoring subsystem, obtaining the prewarning data through analyzing and processing the observation data, and giving out prewarning signals according to the prewarning data; the prewarning subsystem receives the prewarning signals sent by the data center subsystem and performs the prewarning process; and the communication network is used for providing communication for the monitoring subsystem, the data center subsystem and the prewarning subsystem, thereby realizing the real-time monitoring and prewarning function.

Description

technical field [0001] The invention relates to a disaster early warning system, in particular to a geological disaster real-time monitoring and early warning system. Background technique [0002] The current geological disaster early warning system integrates a variety of environmental data measurement components, and uses the communication network to transmit the data and images measured by the measurement components from the on-site monitoring device to the main monitoring device, and then transmit the monitoring information to the responsible unit to speed up the process. Disaster relief work, but the system cannot predict the precipitation in the monitoring area, monitor the quantitative displacement information of the monitoring area or objects in real time, and automatically warn according to the precipitable precipitation and spatial displacement information; at the same time, the system needs to install a large number of sensors, which is costly ; or use rainfall an...

[0002] The current geological disaster early warning system integrates a variety of environmental data measurement components, and uses the communication network to transmit the data and images measured by the measurement components from the on-site monitoring device to the main monitoring device, and then transmit the monitoring information to the responsible unit to speed up the process. Disaster relief work, but the system cannot predict the precipitation in the monitoring area, monitor the quantitative displacement information of the monitoring area or objects in real time, and automatically warn according to the precipitable precipitation and spatial displacement information; at the same time, the system needs to install a large number of sensors, which is costly ; or use rainfall and infrared displacement sensors to transmit to the data center through the wireless network to monitor the actual rainfall intensity, rainfall duration, landslide and subsidence status information and dangerous rock sliding information of landslides and subsidence areas in real time, and comprehensively monitor and evaluate objectively Critical landslide rainfall threshold, landslide evolution process, state, and landslide and collapse grades, but the system cannot predict the amount of precipitation, and the accuracy of displacement information is low, so networked end-user early warning cannot be realized

Fan Yimin et al. (2008) applied GPS technology to early warning of geological disasters in the Three Gorges Reservoir area to provide accurate displacement and deformation information for geological disaster monitoring and early warning; Shu Haichi et al. (2010) improved hardware and software configuration and independent The wireless local area network networking has developed a GPS real-time monitoring system for geological disaster deformation, which has the characteristics of all-weather, automation, and application in complex outdoor environments, and can well ensure the accuracy of monitoring, but does not consider geological disasters such as precipitation and landslides. The correlation between them cannot make comprehensive decisions and early warnings based on information such as displacement information and precipitation.

[0003] The above-mentioned technologies are the latest technologies for geological disaster monitoring and early warning technology, but there are some problems. The various technologies are relatively independent, and the response relationship between the spatial information and the meteorological information in the geological disaster area cannot be considered comprehensively, and it cannot be quickly and directly provided to the geological disaster area. End users provide instant warning information
