La description
The SE***4NTN series seismic data acquisition system is a portable
wired telemetry seismic data acquisition system. This system uses
advanced networking technology for distributed real-time data
acquisition and display. The system is composed of the SE***4NTN
main control unit, a data acquisition station (RSU), a central hub
(CSU), digital transmission composite cables, and remote detonation
decoder. It can be widely applied wherever high precision two or
three dimensional seismic surveying is required, such as surveying
for engineering, coal, minerals, and/or hydroelectric power.
Main Properties
1. Using networking and control technology, the system can be
extended with up to ***8 sensor modules.
2. The main control unit is equipped with two data flow ports and
built-in remote detonation encoder.
3. Real time data display, storage, and playback.
4. Data acquisition modules use true *4 bit high precision analog
to digital converters and open addressing technology, and have
large dynamic ranges, low power consumption, and are easy to
use.
5. Data acquisition modules each has *2 channels, a water-proof
cast-aluminum shell, and are small, lightweight and easy to
maintain.
6. The central hub has a *0Mbps transmission speed and can support
up to **6 modules, and is small, lightweight and easy to
maintain.
7. The transmission range between the remote control encoder and
decoder is *0 km on open ground. The system uses a safety protocol
to raise its reliability and safety. The design includes two high
precision auxiliary channels.
8. The system is developed using Windows, field usage is simple and
quick. The system is designed for both oil surveying seismic
technology and engineering seismic surveying.
