Summary
- Field Laptop Computer
- A rugged laptop computer has been procured and customized by installing the ParkSEIS-HMA (PS-HMA) software package to be used
for field data acquisition and pseudo-real-time on-borad data processing purposes. It has an enhanced computing power, fast solid-
state hard drive, embedded touch-screen capability, and sufficient RAM memory (16 GB) to meet the challenging demands. It has been
used at Park Seismic to test the PS-HMA software developed to handle the 1D-array data and then shipped to Norrfee Tech for the 1st
Joint Field Test (JFT) scheduled on December, 2020.
- ParkSEIS-HMA (PS-HMA) Software Package for 1D-Array Data
- The ParkSEIS software package for this project (ParkSEIS-HMA) has been developed to perform the in-field operation of raw seismic
data collected by using a 16-channel MEMS-microphone-array acquisition system that has been developed at Norrfee Tech. The
algorithmic development that can properly handle different types of wavefields had been finished by the end of last month (October
2020) as summarize in this previous report. Therefore, the Graphical User Interface (GUI) part of the software have been developed
and tested during this month as summarized in this report.
Most components in the "IN-FIELD" module can perform the following tasks:
- Open a "New Project" for a new survey.
- Specify the folder where the raw TDMS data files are saved by the acquisition hardware system.
- Specify the folder where the TDMS data files (*.tdms) are converted and saved into ParkSEIS (PS) format (*.dat) for subsequent
analysis by PS-HMA. All intermediate and final analysis results are also saved in this folder. - Some recording-related parameters (e.g., sampling rate, number of samples, pre-trigger time, etc.) are set here and then passed
into the acquisition-system control software installed at the PXI hardware system. - Some parameters that can control the automatic detection and analysis of signal wavefields (e.g., surgical mute parameters,
wavefield transformation parameters, etc.) can also be specified. - Some parameters that can control visualization of the final results of the shear-wave velocity (Vs) and thickness (H) of the HMA
layer can also be specified. - Once "armed", it notifies the acquisition control software at PXI system to be ready for data collection.
- It detects new raw TDMS files being saved by the acquisition system, converts them into PS-format files, and then executes all
planned data-analysis steps to finally display the results in a fully automated manner.
- All above steps are illustrated by using the Graphical User Interfaces (GUI's) in this report.
- Hardware Development (16-Channel 1D-Array System)
- The development of a 16-channel data-acquisition system by using MEMS microphones is under progress. Some circuit boards had to
be re-designed to use new MEMS microphones as the old components have been discontinued. The new circuit boards are currently
being constructed and the beta version of the 1D acquisition system will be ready for the Joint Field Test (JFT) soon.
