Description
technical field [0001] The invention relates to a digital transmission technology, in particular to a geotechnical engineering digital monitoring wireless transmission method and a device thereof. Background technique [0002] Geotechnical engineering is often referred to as "concealed engineering" and "grey systems". Deformation monitoring plays an important role in all stages of design, construction and operation. It is an indispensable technical measure to ensure the safety of geotechnical engineering construction and operation, and it is a key link in improving geotechnical engineering design methods and construction and operation technical decisions. important basis. Since our country entered the 1970s, safety monitoring work has been carried out in water conservancy and hydropower, It has been widely used and developed in geotechnical engineering in civil construction, railway transportation, coal mining, military industry and other industries, and has been increasi...
