    Abstract: A movement-distance measuring apparatus is provided with: an antenna, a phase detection circuit, a phase-shift calculation circuit, and a movement-distance calculation circuit. The antenna transmits a radio wave toward a plurality of reflectors arranged at constant intervals along a moving path of a moving object, and receives a reflected wave from the reflectors. The phase detection circuit detects a phase of the reflected wave received by the antenna. The phase-shift calculation circuit calculates a phase shift based on the phase detected by the phase detection circuit. The movement-distance calculation circuit calculates a movement distance of the moving object, based on the phase shift calculated by the phase-shift calculation circuit, and based on the interval of the reflectors.

  • Patent number: 10144613
    Abstract: A detection subject body provided in a hoistway includes an ID sequence formed by arranging three or more types of segments having different magnetic properties in a movement direction of an elevating body. An eddy current type detection unit is provided on the elevating body to generate signals corresponding to the magnetic properties of the respective segments. An identification unit identifies the respective types of the segments on the basis of the signals from the detection unit, and outputs a time series signal in a different output condition depending on the type of each segment. A digital data conversion unit converts the time series signal into digital data on the basis of variations in the output condition of the time series signal from the identification unit. A position specification unit specifies the position of the elevating body on the basis of the digital data.

  • Patent number: 10065833
    Abstract: In an elevator position detection apparatus, when a first diagnosis switch is closed, a diagnosis coil generates a first induced magnetic field, and when a second diagnosis switch is closed, the diagnosis coil generates a second induced magnetic field that is weaker than the first induced magnetic field. In a constant L output fault diagnosis mode in which the first induced magnetic field is generated, an output value of a measurement signal falls below a threshold regardless of whether or not a detection subject body is present in a detection region. In a constant H output fault diagnosis mode in which generation of both the first and the second induced magnetic fields is stopped, the output value of the measurement signal equals or exceeds the threshold regardless of whether or not the detection subject body is present in the detection region.
