Dudnik A. Scientific fundamentals of computerized sensory systems for measuring mechanical quantities

For the first time, new principles for the construction of instrumentation systems with the inclusion of wireless sensor devices for measuring mechanical quantities based on the received alternative measurement indicators, due to the function of the localization of sensors in the computerized instrument system, are formulated. New approaches for solving the problem of determining the principle of operation of microprocessor primary measuring transducers included in the wireless sensory devices have been developed for the first time for the creation of computerized instrument systems on their basis and compiled equations for estimating their errors. The model of distance determination based on the arrival time of the signal is improved, which enables to estimate the distance along the front of the impulse and to estimate the error with allowance for obstacles. The computerized laser rangefinder has been improved, which includes a wireless touch interface, which allows to estimate the distance based on two alternative indicators. For the first time, a method for increasing the productivity of computerized sensory measuring systems has been developed, in order to increase the accuracy in transmitting measurement data, which may cause an unreliable estimation of error in sensory devices (protected by Ukrainian patents for utility model No. 60400 and No. 69626). The method of localization of wireless sensors was developed further, which enables to estimate the distance between the sensors, the time of the signal passing between them, and the angle which, in combination with the laser rangefinders, forms a tacheometric sensory device system. The method of determining the distance between objects in the absence of direct visibility, which differs from the existing methods of remoteometry by the fact that the light ray used in them, is not able to propagate along curvilinear trajectories.
