Problems solved by technology
If the monitoring data cannot be obtained continuously and transmitted remotely in a timely manner, the monitoring center will not be able to make a correct evaluation of the stability of the slope. Once the slope becomes unstable, it will not be able to make timely decisions on disaster prevention and mitigation, endangering the safety of the people around the slope. Life and Property Safety

Description
technical field [0001] The invention relates to a remote transmission device for stress measurement data of anchor rods or anchor cables, which relates to the field of stress monitoring of geotechnical engineering slopes. Background technique [0002] At present, the stress monitoring of anchor rod or anchor cable, as an important means of slope stability monitoring, has been more and more used in mining, water conservancy, transportation, construction and other fields. However, compared with the existing stress monitors, many traditional stress monitors that have been buried have shortcomings such as the need to manually collect monitoring data at specific locations on time, the monitoring data is not continuous, and cannot be transmitted remotely. For rock slope stress monitoring, deformation and failure due to changes in the internal stress of the slope are usually completed within a short period of time. If the monitoring data cannot be obtained continuously and transmi...
