The data quality monitoring system of non-cable self-positioning seismographs

Seismic exploration is the most effective and promising geophysical exploration methods, it inverts underground geological structure by recording crust vibration caused by nature or artificial means. In order to get rid of the long-term dependence on imported seismographs, China pays more and more attention to the independent research and development of seismic exploration equipment. This study is based on the self-invented non-cable self-positioning seismographs of Jilin University. Non-cable seismographs have many advantages such as simple arrangement, light, easy to move, easy to maintain, low price, large storage space and high-quality data, they especially apply to complex terrain and field construction environment inconvenient laying big lines. The built-in integration of GPS realizes precise clock synchronization, fast and accurate self-positioning for non-cable seismographs. The low power design and the combination of built-in rechargeable battery and external power can effectively improve non-cable seismographs` working time, which ensures the stability of exploration and construction. In order to solve the problem that the non-cable seismographs are difficult to on-site data monitor and also to provide non-cable seismographs` ability of real-time data transmission, We integrate the wireless communication technology into non-cable seismographs, combing instrument, electronic, communication, computer and many other subject knowledge, design and develop seismic exploration field work control system and seismic data management system. Achieve two research objectives which are real-time data quality monitoring in the resource exploration field and status monitoring of large trace spacing long-term observations for seismographs. Through several field experiments in different regions, we accumulate a wealth of experience, and the experiments effectively prove the good practical performance of non-cable self-positioning seismographs and data quality monitoring system.
