Example Embodiment
[0043] The invention provides a system for monitoring and forecasting the vibration of falling rocks impacting open caves. The system adopts an advanced distributed system architecture, which has the characteristics of high degree of customization, flexible layout, strong real-time, comprehensive functions and full life cycle coverage. It can obtain real-time impact time, location, number of falling rocks, and rockfall energy. The parameters such as the damage to the lining structure of the open tunnel, and the real-time forecast.
[0044] The present invention is a three-level architecture system composed of sensors, collector units and central systems. The sensors are mainly acceleration sensors and video, and the number of acceleration sensors is not less than 5, which are arranged on the roof of the cave. The number of videos is not less than two, one of which is set on the top of the cave so that its visual range covers the entire top of the cave. If there are insufficient ...
