Outline

GMSplus is the ground breaking latest generation of the GeoSIG Measuring Systems with highest performance, excellent operational flexibility and enhanced connectivity.

The unit is based on the GMS technology of NetQuakes Seismographs, which are developed in close coordination with USGS, and deployed in high quantities in North America establishing the NetQuakes network.

It includes an Ethernet connection and optionally a Wi-Fi (b/g/n) module to ensure fast and reliable data transfer. Both wired and wireless network interfaces can be used simultaneously.

Its design and efficiency makes it the first choice for any application requiring seismic instruments. With its optimized installation, operation and maintenance philosophy, the GMSplus offers the real possibility to implement high density arrays with total costs at a small fraction of conventional strong-motion seismograph networks.

The instrument’s software processes data in real time. If triggered by a seismic event, GMSplus calculates a number of Event Parameters and reports them to a data centre immediately.

GMSplus is a self-contained instrument and is equipped with an uninterruptible power-supply, which provides more than 24 hours autonomy.

The GMSplus uses an “Intelligent Adaptive Real Time Clock” (IARTC) with self-learning temperature compensation, improving the accuracy of the RTC or TXCO significantly. The IARTC is able to synchronize with GPS or NTP to UTC timing to provide high timing accuracy. Optionally the unit itself can act as an NTP server as well.

The instrument can be locally connected to a laptop through its ports for configuration, testing or data retrieval. Same functions are available remotely as well.

Wired or Wireless Interconnected Network options enable the use of several units together in a time and trigger synchronised manner. The optional USB support enables the user to connect various external devices such as high capacity storage devices, 3G modems, etc.

  • Specifications
      Set-up and Configuration An intuitive web interface is available for easy configuration with any web browser. Alternatively the configuration file in XML format can be edited on site through the instrument console, exchanged by replacing the memory card, remotely from a server or through SSH. Even if the configuration file can be manually edited at any time, a tool is provided to edit it securely.
      Data Analysis The GeoDAS software provides basic data evaluation in the field meeting the requirements of most scientific and engineering applications. Optionally GMSplus can perform certain analyses onboard.
      Sensor Various GeoSIG sensors as well as a number of other third party sensors can be housed internally or connected externally to the unit. In case of internal sensor, the levelling is done on the base plate of the GMSplus via its three levelling screws. The base plate is mounted using a single bolt during installation.

Outline

CR-6plus is a modern multichannel central monitoring and recording system including a high performance data handling module, providing an extremely flexible 24 Bit multichannel recorder.

Its design is based on years of experience in creating solutions for earthquake, seismic, structural, dynamic and static monitoring.

Its modular architecture and industry standard interfaces offer high versatility, easy expansion, upgradeability, and long term availability of spare parts.

Connection of the sensor cables is extremely easy and fast with the versatile cable screw terminal design. All inputs and outputs of the CR-6plus are protected with a field proven over voltage protection (OVP) system.

Data from acceleration, velocity, displacement, strain, meteorological or any other type of sensors can be monitored and recorded with superior data quality.

The CR-6plus continuously monitors the real-time data, which can be recorded based on event detection and continuously. The continuous ring buffer size, the prevent and post-event time, trigger thresholds and many other parameters are fully user configurable.

In addition to the real-time display of the measured data from each channel the system can provide statistical data such as mean, max, min, and peak values.

CR-6plus can optionally compare the monitored data to four fully independent alarm trigger criteria and provide relay outputs.

GeoDAS, a proven data acquisition and evaluation package developed by GeoSIG, complements CR-6plus providing a highly flexible user-friendly capabilities, and graphical, analytical and reporting tools with automation.
