Description

technical field [0001] The invention relates to the field of seismic signal acquisition, in particular to a single-channel seismic signal acquisition device and a seismic signal acquisition system. Background technique [0002] Seismic prospecting is one of the most important methods in geophysical prospecting. Compared with other geophysical prospecting methods, it has the advantages of high precision, high resolution, and large penetration depth. It has been applied to the exploration of oil, natural gas, and coal deposits, and has achieved great results. It has also played an important role in the search for groundwater resources, the construction of large buildings, dams, roads, railways, ports and other engineering surveys and crustal exploration. [0003] In seismic exploration, according to different detection objects and application purposes, it can be divided into shallow seismic exploration and medium and deep seismic exploration. Shallow seismic exploration is of...

Problems solved by technology

When using a traditional collection system, with the increase in the number of collection stations, the risk of line failure increases, and the normal operation time of the system will be greatly shortened. Sometimes it is time-consuming to repeatedly test the troubleshooting method, which also increases the abnormal operation time. In addition, heavy cables and intensive manpower have caused a certain degree of damage to the ecological environment of the collection site, and going out to collect seismic signals on the spot has increased the health and safety risks of field workers
