Abstract. The equipment for operational non-destructive testing by the shock-wave method developed by the Institute for Geotechnical Mechanics under the National Academy of Sciences of Ukraine, was successfully tested in mine conditions and confirmed the results of theoretical and experimental studies on the possibility of using the relaxation time of free oscillations of a metal-polymer anchor to assess the quality of its fastening. At the same time, some drawbacks of the equipment were identified, which can be eliminated by improving both the data processing unit and the sensor part. The areas of improvements, considered in this work, will improve the stability, speed, mobility and ergonomics of the equipment.
It is possible to improve the data processing unit by implementing modern 32/64 bit ARM microprocessors with higher computing power and with greater variability of circuitry solutions. It is possible to develop a new circuit based on these microprocessors or to use available mini-solutions based on the ARM core. It will also improve the oscillator-receiver unit, potentially making it completely wireless. For both options, it will be necessary to develop software, which, due to the increased computing power, can be improved with additional algorithms for data processing. The increased speed and a larger number of I/O ports will also allow transferring the functionality of the analog part to the ARM microprocessor, which, in turn, will reduce the board size, and the freed space can be occupied by additional batteries to increase the battery life.
The introduction of ARM microprocessors will also allow, thanks to a large number of libraries and circuits for wireless data transmission, the development of anchor vibration sensor with Wi-Fi/Bluetooth data transmission to the processing unit, which, in turn, will increase mobility and ease of use. For maximum ergonomics, it is possible to develop a combined design with an automatic stabilized hammer and oscillation sensor.
Keywords: anchor, shock wave method, non-destructive control, geophysical equipment.
