Abstract

Sonda natężeniowa z układem korekcji składająca się z trzech par mikrofonów, umieszczonych na płytkach drukowanych tworzących sześcian charakteryzuje się tym, że właściwa sonda natężeniowa (1), jest połączona za pośrednictwem interfejsu komunikacyjnego (2), z płytką (3) (DSP), której pierwszym blokiem jest blok wybierania trybu pracy, którego jedno z wyjść jest połączone z układem programowalnych środków filtracji (PSF), którego wejściem jest blok korekcji amplitudy (4), połączony z układem pamięci (5) oraz układem dodatkowego wzmocnienia (6), blok (6) połączony jest z blokiem wyznaczania sumarycznego ciśnienia akustycznego (7), blokiem parametrów dodatkowych (13) oraz blokiem wyznaczania składowych prędkości akustycznej (8), wyjścia bloków (7 i 8) są połączone z blokiem korekcji fazy (9), który połączony jest z układem pamięci (10), wyjście bloku korekcji fazy (9) stanowi jednocześnie wyjście układu (PSF) i jest połączone z blokiem wyznaczania natężenia dźwięku (11), który połączony jest z blokiem pamięci podręcznej (12), blokiem parametrów dodatkowych (13) oraz blokiem wyznaczania kąta azymutu i elewacji (14) oraz blokiem formowania wyniku końcowego (15). Przedmiotem wynalazku jest również sonda natężeniowa z układem kalibracji oraz sposób kalibracji tej sondy.The intensity probe with a correction system consisting of three pairs of microphones placed on printed circuit boards forming a cube is characterized by the fact that the correct intensity probe (1) is connected via a communication interface (2) to the plate (3) (DSP), which the first block is the mode selection block, which one of the outputs is connected to the programmable filtration system (PSF) system, whose input is the amplitude correction block (4), connected to the memory system (5) and the additional gain system (6), block ( 6) is connected with the block for determining the total sound pressure (7), the block for additional parameters (13) and the block for determining the sound speed components (8), the outputs of the blocks (7 and 8) are connected to the phase correction block (9), which is connected with the memory circuit (10), the output of the phase correction block (9) is also the circuit output (PSF) and is connected to the set a sound determination curl (11), which is connected to a cache block (12), an additional parameter block (13) and an azimuth and elevation angle block (14) and a final result block (15). The invention also relates to a current probe with a calibration system and a method for calibrating this probe.
