Principe de mesure <\/strong><\/h3>\n

Au cours du processus de mesure de distance, des signaux ultrasoniques sont \u00e9mis par une sonde ultrasonore, r\u00e9fl\u00e9chie par des liquides ou d'autres milieux solides, puis retourn\u00e9e. La m\u00eame sonde re\u00e7oit ces signaux r\u00e9fl\u00e9chis. En mesurant la diff\u00e9rence de temps entre l'\u00e9mission et la r\u00e9ception des ondes ultrasonores, on obtient une mesure de niveau. La relation entre la distance de transmission \u00e0 ultrasons L, la vitesse du son v et le temps de transmission \u00e0 ultrasons t peut \u00eatre exprim\u00e9e par la formule:<\/p>\n

La formule de calcul de base pour la mesure de distance par ultrasons est la suivante : L = (v \u00d7 t) \/ 2<\/b><\/strong><\/p>\n

L : Distance entre la sonde \u00e0 ultrasons et la surface du mat\u00e9riau mesur\u00e9. Unit\u00e9 : m\u00e8tre (m) ;<\/p>\n

v : Valeur de la vitesse du son apr\u00e8s compensation de temp\u00e9rature. Unit\u00e9 : m\u00e8tre par seconde (m\/s) ;<\/p>\n

t : temps de propagation de l'onde sonore dans la plage de mesure. Unit\u00e9 : seconde (s)<\/p>\n

Description du produit<\/strong><\/h3>\n

Le capteur d'\u00e9vitement sous l'eau \u00e0 cinq faisceaux est un capteur \u00e0 ultrasons multifaisceaux d\u00e9velopp\u00e9 selon le principe d'autotransmission et d'autor\u00e9ception des ondes ultrasoniques. Il adopte une m\u00e9thode d'essai de la bobine ronde de “cinq transmissions et une r\u00e9ception” mise en \u0153uvre par un logiciel interne, ce qui permet de s'\u00e9tendre dans cinq directions. Gr\u00e2ce aux essais coordonn\u00e9s de ces cinq directions, les fonctions d'\u00e9vitement des obstacles sous-marins et de port\u00e9e sous-marine sont r\u00e9alis\u00e9es. Le capteur peut stocker les donn\u00e9es d\u00e9tect\u00e9es dans le registre interne des puces, communiquer avec l'ordinateur h\u00f4te via le protocole Modbus, et prendre en charge le r\u00e9glage du capteur & #8217;s upload passif et les modes de t\u00e9l\u00e9chargement actif.<\/p>\n
