IMPROVING THE NAVIGATION SYSTEM OF UNDERGROUND PIPE DEFECT DETECTION DEVICE

This article addresses the issue of noise and drift in microelectromechanical gyroscopes and their impact on measurement accuracy in engineering applications. The use of a complementary filter is proposed to combine information from the accelerometer and gyroscope to reduce inaccuracies. Research shows that the accelerometer has better result repeatability, which is important for obtaining stable measurements. At the same time, the gyroscope may be more effective in measuring translational movements.

DEVELOPMENT OF THE ACCELERATION MEASURING METHOD

The existing acceleration measuring methods are analyzed in the article. An overview of modern research on this topic is also provided. A new method of measuring acceleration in the form of an electrical circuit using a stable frequency generator is developed. Among the already known methods, the following three groups are highlighted in the analysis: methods based on compensatory accelerometers with discrete output; methods based on accelerometers with the analog-to-digital converter; measurement techniques, which use mounted elements.

Accelerometer sensing element based on nanostructured silicon

In this work we consider sensing elements of an accelerometer which is made using the combined technologies of silicon-on-insulator (SOI) structures and silicon nanocrystals whiskers manufacturing. On their basis a quick-response, high sensitive to acceleration and displacement device with submicrometer and nanometer typological sizes has been designed.

Seismic observations at the temporary stations in the area around the Zaporizhzhya NPP

Purpose – to organize a temporary network of seismic observation tool for continuous collection of information on seismic events in the area of the Zaporizhzhya NPP. Methods. In the bomb shelter in the territory dispensary Zaporizhzhya NPP, organized a temporary observation points to maintain a register of certified seismometer seismic events GURALP CMG-40TD. Choosing a place for the installation of temporary seismic observation point due to occurrence of bedrock in this place at least in the area ZAES depth (about 8 m).
