Description

technical field [0001] The invention relates to the technical field of geotechnical engineering safety monitoring, in particular to a dam safety monitoring system and method based on the Internet of Things. Background technique [0002] The traditional dam structural safety monitoring is divided into three stages according to the time sequence of the project construction, namely the monitoring during the construction period, the initial water storage period and the operation period. During the construction period, sensors are gradually buried in dams and other buildings according to the progress of the project. During the initial water storage period, semi-automatic monitoring can be achieved because the auxiliary facilities of the monitoring station are not fully completed. Only in the running period can an automatic monitoring system be established to realize automatic monitoring. [0003] The traditional dam structural safety monitoring system consists of various sensor...

Problems solved by technology

This type of monitoring system has the following characteristics: during the construction period, the initial impoundment period and the operation period, different monitoring methods are adopted, gradually transitioning from manual and semi-automatic monitoring to automatic monitoring, especially the automatic monitoring cannot be realized during the construction period, which requires a lot of manpower and material resources; a large number of sensors are scattered and installed in different installation areas of the dam, and the sensors are connected to the data acquisition device through cables, which consume a large number of cables, high material costs, difficult construction, and high labor costs; data acquisition devices need to be connected to different types Various types of sensors, the circuit design is complicated and the cost is high; the communication between the data acquisition device and the data convergence center is divided into wired or wireless methods, and the data acquisition device needs to take into account different communication methods, which are very different and complex in design; The number of sensors connected to the acquisition device is limited. For monitoring applications that require access to a large number of sensors, multiple data acquisition devices need to be networked. After networking, they will communicate with the acquisition computer or remote data center, resulting in a complex system structure; It is necessary to take into account the monitoring principles and monitoring frequency requirements of all sensors connected. Due to the unbalanced power consumption of each part, the overall power consumption of the acquisition device is large
