Abstract
(EN)
This invention detects an abnormal state when the main power supply of electronic equipment is cut off. In this invention, an antenna includes an antenna element for receiving radiation noise radiated from a device on a circuit board of electronic equipment and a resonant circuit that is connected to the antenna element and has an adjustable resonant frequency. The antenna outputs a reception signal representing the radiation noise. A sensor monitors the reception signal and detects an abnormal state when the main power supply of the electronic equipment is cut off.

La présente invention concerne un dispositif et un procédé pour détecter un état anormal lorsque l'alimentation électrique principale d'un équipement électronique est coupée. Dans l'invention, une antenne comprend un élément d'antenne pour recevoir un bruit de rayonnement irradié à partir d'un dispositif sur une carte de circuit imprimé d'un équipement électronique et un circuit résonnant qui est connecté à l'élément d'antenne et a une fréquence de résonance réglable. L'antenne émet un signal de réception représentant le bruit de rayonnement. Un capteur surveille le signal de réception et détecte un état anormal lorsque l'alimentation électrique principale de l'équipement électronique est coupée.
