Abstract
(EN)
In a bridge circuit (10), a series circuit (11) is formed in such a manner that a resistor (R1) and a resistor (R2) are connected in series, and a resistor (R2) and a resistor (R4) are connected in series. In the bridge circuit (10), the series circuit (11) and a load section (R3) are connected in parallel, one end of a resistor (R5) is connected to a point between the resistor (R2) and the resistor (R4), and the other end of the resistor (R5) is connected to a point between the resistor (R1) and the load section (R3). In the bridge circuit (10), a voltage supply (20) is connected to a point between the resistor (R1) and the resistor (R2). A control unit (40) detects an abnormality in the load section (R3) on the basis of the detected voltage across the bridge circuit (10) detected by applying a voltage (V) from the voltage supply (20) while a switch (3) is off. This structure enables an abnormality detection device (1) to detect an abnormality while limiting the increase in size of the device.

La présente invention concerne un montage en pont (10), dans lequel un montage en série (11) est formé de telle manière qu'une résistance (R1) et une résistance (R2) sont montées en série, et une résistance (R2) et une résistance (R4) sont montées en série. Dans le montage en pont (10), le montage en série (11) et une section de charge (R3) sont montés en parallèle, une extrémité d'une résistance (R5) est connectée à un point entre la résistance (R2) et la résistance (R4), et l'autre extrémité de la résistance (R5) est connectée à un point entre la résistance (R1) et la section de charge (R3). Dans le montage en pont (10), une alimentation en tension électrique (20) est connectée à un point entre la résistance (R1) et la résistance (R2). Une unité de commande (40) détecte une anomalie dans la section de charge (R3) sur la base de la tension électrique détectée dans le montage en pont (10) détectée par application d'une tension électrique (V) à partir de l'alimentation en tension électrique (20) tandis qu'un commutateur (3) est désactivé. Cette structure permet à un dispositif de détection d'anomalie (1) de détecter une anomalie tout en limitant l'augmentation de taille du dispositif.

ブリッジ回路(10)は、抵抗(R1)と抵抗(R2)とが直列に接続され、抵抗(R2)と抵抗(R4)とが直列に接続された直列回路(11)が形成される。そして、ブリッジ回路(10)は、直列回路(11)が負荷部(R3)と並列に接続され、抵抗(R5)の一端が抵抗(R2)と抵抗(R4)との間に接続され、抵抗(R5)の他端が抵抗(R1)と負荷部(R3)との間に接続される。そして、ブリッジ回路(10)は、電圧供給部(20)が抵抗(R1)と抵抗(R2)との間に接続される。制御部(40)は、スイッチ(3)をオフした状態で電圧供給部(20)から電圧(V)を印加することにより検出したブリッジ回路(10)の検出電圧に基づいて負荷部(R3)の異常を検出する。この構成により、異常検出装置(1)は、大型化を抑制した上で異常を検出することができる。
