Wireless sensor network-based slope real-time security monitoring system

Abstract

The invention discloses a wireless sensor network-based slope real-time security monitoring system and relates to the security monitoring field of geotechnical engineering. The system comprises a slope monitored area data acquisition layer, a data transmission layer and a remote security monitoring center, wherein the data acquisition layer comprises an information acquisition node, a routing node and a coordinator node; the data transmission layer is composed of a GPRS / CDMA data transmission device accessing the Internet, the observed data of all the sensor nodes are transmitted to a remote high-slope security monitoring center through the data transmission layer; and the remote security monitoring center is a Web back-stage management system which contains a treatment and display system for monitoring data, a remote operation system, an remote management system of the acquisition equipment, an early-warning and release system and a user management system. The system of the invention realizes complete digitization in intelligence sensing detection, transmission, reception and treatment, also realizes the real-time acquisition and secure transmission of slope data under harsh environment and provides reliable data for the health diagnosis of slope engineering, the establishment of early-warning standard and the control of landslide.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering safety monitoring research, in particular to a real-time safety monitoring system for slopes based on a wireless sensor network. Background technique [0002] For large and complex slopes, in addition to timely and effective support measures, the deployment of advanced safety monitoring systems and timely analysis and feedback of monitoring results are important guarantees for safe construction and dynamic optimization of slopes. As an indispensable and important part of slope engineering, safety monitoring can monitor the safety of slope construction and operation periods, and provide objective and real data for information design during construction and guide on-site construction. Therefore, with the development of social economy, the slope safety monitoring system has been paid more and more attention. Especially since the 1990s, the hardware and software of geotechnical engineering saf...

Problems solved by technology

However, slopes generally monitor a wide range of areas. Traditional monitoring cable laying is a complex project, and the price is expensive. It is inconvenient to adjust, expand, and maintain monitoring points, and the detection, transmission, reception, and processing of monitoring data are difficult. Without real digitalization and networking, the continuity of space and time monitoring has not been truly satisfied, which affects the real-time and accuracy of monitoring data transmission and analysis, so that real-time dynamic feedback analysis and evaluation of slope development cannot be performed
