GD-3C:4G Real-time Monitoring Nodal Seismic Instrument
GD-3C is a wireless seismic sensor that uses advanced GPS/Beidou synchronization algorithms. It weighs only 1450g and measures only 90x100x128 mm. It can work in extreme environments such as high temperature, high pressure, high gas content, and high sand content. It has the advantages of high efficiency, reliability, and flexibility.
Seismic acquisition is a technology used to detect and monitor underground structures and resources. It generates artificial seismic sources on the surface or in wells, receives and records seismic wave signals reflected or refracted by underground media, and then processes and interprets them to obtain physical parameters and morphological characteristics of the underground. Seismic acquisition is widely used in many industries such as oil, natural gas, coalbed methane, carbon capture and storage (CCUS), geothermal, and mining. However, traditional seismic acquisition technology also has many problems, such as bulky and expensive equipment, difficult deployment, complex maintenance, low data quality, and large environmental impact. In order to solve these problems, the company has launched an innovative seismic node acquisition sensor-GD-3C, which is currently the world's smallest, lightest, and most efficient land seismic sensor.
01 Technical Principle
1.GPS/Beidou synchronization algorithm: This algorithm ensures that the seismograph can accurately and synchronously record seismic data, improving the accuracy of data analysis.
2. Ultra-low power circuit design: This design enables the seismograph to work continuously for a long time and adapt to various complex surfaces and harsh environments.
3. Real-time data communication technology: By transmitting data in real time, the timeliness and accuracy of the data are ensured.
4. Analog-to-digital conversion design: The most advanced analog-to-digital conversion design enables the seismograph to monitor even smaller vibration signals, thereby improving the sensitivity and accuracy of the seismograph.
5. High integration: The Ant-3C seismograph has a high degree of integration and a full-body contactless design, which further enhances its stability and durability.
The combination of these technologies enables the Ant-3C seismograph to work stably for a long time in various complex and harsh environments, while providing high-precision seismic data, which is of great significance for earthquake research and early warning.

05 FQA
1.Q:What is a node seismograph?
A: A node seismograph is a high-precision seismic data acquisition device, mainly used to capture and record seismic waves. This instrument usually has a built-in velocity sensor, data storage and transmission unit, supports wireless communication, and can perform real-time data viewing and monitoring. It is compact, lightweight and durable, and is suitable for a variety of fields such as oil and gas, coal fields, and engineering exploration.
2.Q:The difference between a node seismograph and a traditional seismograph?
F:Compared with traditional wired seismographs, node seismographs have the advantages of small size, light weight, and flexible deployment. They do not require traditional cable connections, reduce physical connections between devices, and reduce environmental risks and operating costs. Node seismographs usually have built-in time synchronization systems, which can achieve synchronization accuracy of less than 3 microseconds between multiple hosts. In addition, they support unattended autonomous acquisition, monitor instrument status in real time through wireless communication, and improve the flexibility and convenience of data acquisition.
3.Q:How to choose the right node seismometer?
F:There are several factors to consider when choosing a suitable node seismometer. First, choose the appropriate instrument type according to the application scenario, such as oil and gas exploration, engineering exploration, or earthquake monitoring. Second, pay attention to the technical parameters of the instrument, including sampling rate, resolution, storage capacity, and working time. It is also necessary to evaluate its protection level and weather resistance to ensure stable operation of the equipment in harsh environments. Finally, consider data transmission and real-time monitoring functions, and choose equipment that supports multiple wireless communication methods to achieve convenient data management and monitoring in the field.
