MOVING BODY DETECTION SYSTEM

WIPO Patent Application WO/2019/012745

A1

This moving body detection system is for detecting a moving body on a travel path, and comprises a reflection part for reflecting transmission waves, a measurement unit for emitting transmission waves toward the reflection part and measuring reflected transmission waves, and a data processing unit for processing measurement data from the measurement unit. The reflection part and measurement unit are provided on opposite sides of the travel path for the purpose of detecting a moving body at a prescribed location on the travel path. If, on the basis of the measurement data from the measurement unit, the data processing unit determines that the measurement unit has received a prescribed amount or more of transmission waves that have been emitted by the measurement unit toward the reflection unit and reflected, the data processing unit determines that the moving body is not at the prescribed location and that measurement using the reflection part and measurement unit is normal, whereas if, on the basis of the measurement data from the measurement unit, the data processing unit determines that the measurement unit has not received the prescribed amount or more of the reflected waves, the data processing unit determines that the moving body is at the prescribed location.
