摘要： 전자기유도센서에의해차량의차종, 진행방향을검지하는기술을제공한다. 전자기유도센서인센서부(10)는송신코일(TX1), 제1 수신코일(RX1), 제2 수신코일(RX2)을구비한다. 강재인차량(90)의자계에의해송신코일(TX1)의방출자계가끌어당겨진다(S1). 차량(90)이가까워지면파선으로나타낸상태1에서일점쇄선으로나타낸상태 2로변화한다(S2). 제1 수신코일(RX1) 상태 1의자계때(차량비검지때)의유기전압에대하여유기전압저하와위상변화가발생한다(S3). 제2 수신코일(RX2)과제1 수신코일(RX1)의차동출력신호가차량진행에맞추어차량저부(92)의요철이나금속종류별에맞추어변화한다(S4). 차동출력신호를수신레벨과위상차의직교좌표로나타낸궤적화상이차량마다상이함으로써차종판별이가능해진다.

摘要： Provided is a technique for detecting a vehicle type and a traveling direction of a vehicle by an electromagnetic induction sensor.A sensor unit (10), which is an electromagnetic induction sensor, includes a transmission coil (TX1), a first reception coil (RX1), and a second reception coil (RX2). A magnetic field of a vehicle (90) made of steel attracts a magnetic field emitted from the transmission coil (TX1) (S1). As the vehicle (90) approaches, a state 1 indicated by the broken line changes to a state 2 indicated by the dash-dot line (S2). A reduction in induced voltage and a phase change occur with respect to the induced voltage when the first reception coil (RX1) is in the magnetic field of state 1 (when the vehicle is not detected) (S3). The differential output signals of the second reception coil RX2 and the first reception coil RX1 change according to the advancement of the vehicle and according to the unevenness of the vehicle bottom portion 92 and the metal species (S4). The trajectory image representing a differential output signal in rectangular coordinates of a reception level and a phase difference is different for each vehicle, so the vehicle type may be distinguished.

摘要： A railroad equipment state determination apparatus (1) includes: a storage (300) that stores a plurality of operation data associated with a prescribed operation performed by railroad equipment that is driven by a motor from a stopped state to perform the prescribed operation and then comes into the stopped state again; an evaluation criteria setting section (204) that sets evaluation criteria based on the plurality of operation data stored in the storage (300); and a determination section (210) that determines whether new operation data resulting from the prescribed operation newly performed by the railroad equipment is abnormal based on the evaluation criteria.
