GD-ANT-1C is a lightweight, convenient and stable seismic nodal instrument. Aiming simplify seismic exploration, improving construction efficiency and saving project cost. The product adopts advanced GPS / BDS synchronization algorithm, ultra-low power circuit design and wireless data download / charging technology. High product integration, long continuous working time, IP68 waterproof, great potential for intelligent / automatic construction, and adapt to various complex surfaces and rugged environments.
Compared with traditional seismographs, the advantages of node seismographs are: flexibility, efficient construction, strong anti-interference ability, no distortion of data, no damage to buildings or underground pipelines, green and environmental protection, portability, resistance to harsh outdoor environments, stable and consistent data, strong structural stability and environmental adaptability.
Flexibility: The node seismograph layout is very flexible and simple, and can be constructed efficiently and at low cost. It can quickly deploy two-dimensional and three-dimensional observation systems in various complex terrains and geographical environments.
Efficient construction: Each node is an independent unit and can be arranged in different locations as needed to meet the needs of engineering projects of different complex terrains and scales, reduce the laying of cables, improve work efficiency, and reduce engineering costs.
Strong anti-interference ability, no distortion of data: The node seismograph has strong anti-interference ability, which can ensure the authenticity and accuracy of data collection, and will not cause data distortion due to external interference.
No damage to buildings or underground pipelines: When conducting underground cavity surveys and other operations, the use of node seismographs will not cause any damage to buildings or underground pipelines, ensuring construction safety.
Green and environmental protection: Since the construction process does not involve destructive operations, the use of node seismometers is in line with the concept of green environmental protection.
Portable: The node seismometer adopts a detachable design, does not require external cable connection, has a high-sensitivity seismic sensor and a high-precision GPS receiver, can adapt to harsh outdoor environments, and has stronger structural stability and environmental adaptability.
Stable and consistent data: Each node has an independent data acquisition system with high time consistency. It uses advanced technology and production processes to ensure the consistency of all nodes and avoid data consistency problems that may occur in wired seismometers.
In summary, node seismometers have broad application prospects in geological exploration, urban underground space exploration and other fields due to their unique advantages
