摘要

Accidents that happen on the Urban Railway or in railroad operating institutions can sometimes involve passengers and often occur with night workers who are carrying out system maintenance and management duties. Various safety related systems and technologies are currently being developed in order to prevent accidents from happening, but it is difficult to find a system that is safe and reliable in regards to unforeseen circumstances of duties carried out at night, on and off the tracks, as well as in tunnels. Despite continuous health and safety education, collision accidents between workers and operating vehicles (motorcars) during maintenance and management at night are regularly occurring, threatening precious lives and rendering the loss of property. The purpose of this paper is to prevent accidents between trains, between motorcars, and between trains and people in the Urban Railway and railroad operating institutions through an RT-ToF (Round Trip Time of Flight), appropriate for vehicles and trains, by developing a device that can trace the distance and location by using an RF module.
