Study of Automated Control System of Underwater Dosimetry Kit in Remote bottom radioactivity measurement in deepwater Areas

Abstract

The paper presents a study of the automated control system of the underwater radio-controlled unmanned vehicle (as a prototype) which monitors the radiation in the deepwater area bottom (with the depth over 10 m), and a system of the operator-vehicle communication line. A standard approach to the radiation monitoring is applied with the help of spectrometric and dosimetry equipment, as well as an echo sounder mounted on the underwater vehicle. The communication line with a facility located on the ground is exercised in the following two ways: when in water, it is arranged through the information transmission by ultrasound to the buffer gear floating on the surface of the water area, and through the gear it gets in a retransmission to the operator on the ground via a radio channel. The control of the underwater vehicle is exercised in the reversed sequence: from the operator to the buffer gear, it goes through a radio channel, then it goes from the latter to the underwater vehicle by the retransmission into ultrasound, and then it reaches the receiving device of the underwater vehicle through further retransmission.
