It is determined that the main tasks for the monitoring of technological processes at an enterprise are the collection, storage, visualization, preliminary analytical and intellectual processing of technological data in real time. The requirements have been formed and the principles of developing a monitoring system for technological processes in the enterprise have been selected, the main ones are modularity, system integration, openness and compatibility.
Design principles of toolkit for characteristics investigation of the digital signal processors generated by Chameleon© C2HDL design tool and implemented to the FPGA of Altera DE1-SoC platform are considered. The structure and organization of toolkit and its components, including the digital signal processor synthesis and implementation in FPGA flow are described. The chain of DSP performance investigation which are generated by the Chameleon© C2HDL design tool using toolkit is formed.
The task of signal recovery is one of the most important for automated diagnostics and control systems. This task is computationally complex, especially when there are a lot of heterogeneous errors in the signals and recovery is to be performed in real time. The article deals with the application and investigation of a modified algorithm for the method of quadrature formulas for the numerical solution of the Volterra integral equations of the I kind in solving the problem of signal recovery in real time.
Nowadays, industrial development creates new and more complex processes leading to emergence of specific conditions for use of sensors and therefore specific measurement tasks. These circumstances lead to new requirements both for the methods of measurement and for sensors that implement these methods. Developments in microelectronic technologies and materials science have led to a significant number of types of pressure sensors.
Nowadays the problem of quick-changing non-stationary values measurement is extremely actual in various modern technical systems (parameters control of engine combustion chamber, testing of aerospace complex products, scientific researches etc.). There are sufficiently effective ways of such measurement. However, increase in the speed of such methods is needed urgently. The attempt of finding the new approach to the problem of sensor output signal processing when measuring non-stationary values using the example of non-stationary pressure measurement by piezoresistive sensors is presented.
