Description

Technical Field

[0001] The utility model relates to the technical field of seismic exploration, in particular to a node instrument for collecting seismic wave data for underground space detection in complex environments. Background Art

[0002] With the increasing demand for the development of underground space resources, traditional underground space detection technology has gradually become unable to meet the high-precision requirements in current geological exploration, especially in underground spaces in complex environments such as urban roads, mining areas, and woodlands. Therefore, the development and innovation of underground space detection technology is of great significance to ensure the effective utilization of resources and sustainable development. Underground space exploration and development mainly rely on geophysical exploration technology. Geophysical exploration technology can effectively detect underground structures and their physical properties, thereby assisting underground space exploration and development. In view of the complex characteristics of underground geological structures and the unique physical properties of different detection targets, a variety of geophysical exploration technologies have emerged, such as seismic exploration, gravity exploration, electromagnetic exploration, and electrical exploration. At present, seismic exploration is one of the most commonly used geophysical exploration technologies in underground space exploration.

[0003] Seismic exploration uses artificial or naturally generated seismic waves to measure the time and speed of their propagation underground to infer the underground geological structure. The seismic data acquisition system is the core equipment for realizing seismic exploration, which is mainly divided into wired seismic data acquisition system and wireless seismic data acquisition system. For a long time, seismic exploration has generally used wired seismic data acquisition systems to complete data acquisition tasks. The wired seismic data acquisition system connects the detector to the acquisition unit and transmits the collected seismic wave data to the data monitoring vehicle through media such as cables or optical cables. However, with the increasingly complex conditions of resource exploration, the wired system faces problems such as difficult deployment and low construction efficiency.

[0004] The wireless acquisition system for underground space detection seismic wave data, also known as the wireless acquisition node for underground space detection seismic wave data, can be divided into two types according to whether it supports real-time data recovery: non-real-time wireless acquisition node for underground space detection seismic wave data and real-time wireless acquisition node for underground space detection seismic wave data. Compared with the wired system, the wireless system does not require cable or optical cable connection, and has the advantages of flexible deployment, lightness, reliability and easy operation. The non-real-time wireless acquisition system for underground space detection seismic wave data independently completes data acquisition and stores the data in the memory card, which will be uniformly recovered by the survey personnel after the task is completed. In recent years, with the development of wireless transmission technology, the real-time wireless acquisition system for underground space detection seismic wave data has become a research hotspot. On the basis of independently completing data acquisition, the real-time wireless acquisition system transmits the system status or collected data in real time through wireless technology, which provides higher data quality control and faster fault detection time compared with the non-real-time wireless acquisition system.

[0005] In the existing technology, underground space detection systems have problems such as low integration, low data accuracy, and difficulty in supporting large-scale real-time wireless transmission. Therefore, improving the comprehensive performance of existing underground space seismic wave detection technology and optimizing seismic wave data acquisition and transmission systems are the key to the future development of underground space detection technology.
