Title: Innovations by Hiroshi Taoka

Introduction

Hiroshi Taoka is a notable inventor based in Hitachinaka, Japan. He has made significant contributions to the field of train control systems, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of train operations through innovative technologies.

Latest Patents

One of Taoka's latest patents is a train position detection system. This system enables accurate train position detection by combining passing information obtained when a train passes over a ground marker with position information stored in an onboard device. The onboard device, along with a ground marker receiver and a track digital telegram receiver, is mounted on the train. The ground marker transmits passing information to the onboard device, while a ground device sends a track digital telegram containing position information about the ground marker. This allows the onboard device to determine the train's position based on the received data.

Another significant patent is the automatic train stop system. In this system, a track circuit is divided into sections, and digitized train control information is transmitted through these sections on carriers with different frequencies. A carrier sensor mounted on the train detects the carrier in the track circuit and identifies the track circuit boundary by recognizing a level change. This information is crucial for the onboard system to control the train effectively.
