Dzs 1 Deep Digital Seismograph - China

Specifications

Mainly utilizes explosion and huge seismic wave to detect

the characteristics and properties of crustal deep structure

Main Applications

DZS- 1 Deep Digital Seismograph is a kind of 3D data

acquisition device.

Mainly utilizes explosion and huge

seismic wave to detect the characteristics and properties of

crustal deep structure; microseismic detection can also be

used in the research of natural earthquakes, 3D seismic

survey of oil field gas, etc, especially for long time

unattended testing

System consists of data acquisition device, zero time

receiver and built- in geophone.

Reflection and Refraction

Exploration: Bedrock embedded depth, shape and regularities

of distribution research, hydrological and engineering and

environmental geological basic investigation.

Main Features

Timing power- on for data acquisition and power- off upon

completion, automatic data storage

GPS time service, geographical location targeting

3D Observation

32- bit A/ D converter, high precision and high dynamic range

can be reliably guaranteed

Low- noise design, system noise is lower than 1μ V

PDA or laptop computer operation

Industrial CF card data storage, safe and reliable

Small- sized, water- proof, shock- proof, anti- interference

sampling completion.

Documentation: One data file can be formed at each sampling,

and every file contains the following texts: instrument

number, station index number, sampling rate, amplification

times, time synchronization time before GPS, sampling stat

time, sampling stop time, synchronization time after GPS,

GPS latitude, GPS longitude, GPS elevation, voltage before

lithium cell, voltage after lithium cell, sampling point

data.

Length of Data File Name, 8- Bit: The first 6 digits for

station index number, the 6 digits for file name ( 01, 02,

……30)

Development of PC software sampling VC 6.0, which can be

used for WINXP system

Adopt USB 2.0 interface for data transmission with PC

With PDA, easy for field work; PDA is to complete parameter

setting of field work ( sampling time synchronization, time

synchronization, GPS information acquisition and input,

sampling time interval setting, etc.

)

Both PC and PDA have functions for clearing data on FD card
