What is a slope? The literal meaning to understand is actually refers to the natural or artificial role in the formation of a certain degree of inclination of the rock and soil body slopes, in the natural environment widely exist. The geographic location of the transmission line slope is usually more special, may be located in mountainous areas, hilly areas and other topographical complexity of the region, these places have a variety of geological conditions, soil structure, rock distribution and other circumstances vary, to the stability of the slope brings a lot of uncertainty.
Natural erosion is a serious problem facing the slopes of transmission lines. Long-term wind and sunshine and other natural factors will gradually erode the soil and rock on the surface of the slope, reducing the strength of the slope, especially in some areas with loose soil, the speed of natural erosion is faster, which may lead to cracks and collapse of the slope. Once the slope destabilization occurs, it will not only affect the normal operation of the transmission line, but also may cause secondary disasters, threatening the surrounding environment and the life and property safety of the personnel.
Rainwater scour is also one of the major challenges that outdoor slopes need to deal with. During rainfall, rainwater flows down the slope surface, creating a scouring force of water. This scouring force will carry away soil particles from the slope surface, causing the slope to gradually steepen and become less stable. In addition, rainwater may also seep into the interior of the slope, increasing the water content of the soil and reducing its strength, further aggravating the instability of the slope.
More critically, the consequences of slope instability are not only ecological, transmission lines as an important infrastructure, once the slope problems, resulting in tower base instability, it is likely to cause accidents such as tower collapse, disconnection and so on. The traditional manual detection method in the face of such a complex mountain slope situation is faced with a long detection period, can not be real-time monitoring, data accuracy affected by human factors and many other shortcomings.
In response to the above phenomenon, SHENZHEN DINGXIN WISE TECHNOLOGY CO.,LTD independently researched and developed and launched the slope online monitoring system DX-BDS100-BP, professionally known as Transmission line slope online monitoring device, through the high precision sensor, it can capture even the extremely small displacement changes on the slope surface in real time. Even just a few millimeters of movement, can not escape its "eyes", can find the potential risk.
The slope online monitoring system adopts BeiDou automated monitoring technology to acquire the 3D coordinate changes of monitoring points in real time, and send them to the control center for analysis and early warning through data communication network. The device is powerful, including high-precision data acquisition and transmission, automatic solving and evaluation, diversified alarm methods, real-time monitoring of slope deformation and landslides, etc., and provides location data with millimeter-level accuracy. Meanwhile, the system adopts modularized design, which is convenient for on-site installation and maintenance, and can operate reliably for a long period of time in 7×24 hours to meet the various needs of power tower deformation monitoring, automatically generate reports and can be outputted according to the user's self-designed cycle.
