    • There is provided a laser radar apparatus including laser beam generating means, photo detecting means, a mirror assembly, light deflecting means, and rotation driving means. The laser beam generating means emits a laser beam having an axis thereof. The photo detecting means detects a reflected laser beam that is reflected back by an object. The mirror assembly includes a through-hole that transmits the laser beam and a reflecting surface that reflects a reflected laser beam reflected back by the object toward the photo detecting means. The light deflecting means has a flat mirror surface and a concave-shaped mirror surface, and reflects the laser beam toward a measurement range and deflects the reflected laser beam from the object toward the mirror assembly. The rotation driving means rotates the light deflecting means so as to direct the laser beam toward the measurement range.

    • An electrical leakage determining circuit determines the occurrence of electrical leakage at a negative electrode of a fuel cell when a potential difference V between a positive electrode of the fuel cell and ground, which is detected by a potential difference detecting circuit, exceeds a preset potential difference threshold Vth, and determines the occurrence of electrical leakage at the positive electrode of the fuel cell when an insulation resistance R between the positive electrode of the fuel cell and ground, which is detected by a resistance detection circuit, falls below a resistance threshold Rth preset to be equal to or smaller than a resistance value Rw of a coolant. Upon determination of the occurrence of electrical leakage, the electrical leakage determining circuit opens a switching contact provided on a power supply line to interrupt power supply from the fuel cell to various power consumption components.

    • An abnormality detecting device for a fuel cell powered industrial vehicle confirms whether a radiator fan is at rest or not (S1), and when the fan is at rest, a first setting concentration N1 is selected and set as an abnormality detection threshold value TH (S2). Conversely, when the fan is driven, a second setting concentration N2 for detecting a lower concentration is selected and set as the abnormality detection threshold value TH (S3). A hydrogen concentration Nm detected by a hydrogen concentration sensor is input (S4), and the input hydrogen concentration Nm is compared with the abnormality detection threshold value TH (S5). If the detected hydrogen concentration Nm is lower than or equal to the abnormality detection threshold value TH, it is determined as normal (S6), and if the detected hydrogen concentration Nm exceeds the abnormality detection threshold value TH, it is determined as abnormal (S7).
    • 用于燃料电池供电的工业车辆的异常检测装置确认散热器风扇是否处于静止状态(S1),并且当风扇静止时,选择第一设定浓度N1并将其设置为异常检测阈值TH( S2)。 相反,当风扇被驱动时,选择用于检测较低浓度的第二设定浓度N2并将其设置为异常检测阈值TH(S3)。 输入由氢浓度传感器检测出的氢浓度Nm(S4),将输入氢浓度Nm与异常检测阈值TH进行比较(S5)。 如果检测到的氢浓度Nm小于或等于异常检测阈值TH,则判定为正常(S6),如果检测到的氢浓度Nm超过异常检测阈值TH,则判定为异常(S7 )。
