Train detection system and a train detection method
First Claim
1. A train detection system comprising:
- transmitters, each of which is connected to a track circuit and transmits to the track circuit a train detecting signal;
receivers, each of which is connected to the track circuit and receives the train detecting signal from the track circuit; and
a control device on the ground, which transmits the train detecting signal to said transmitter and receives the train detection signal from said receiver;
wherein said transmitter adds a first unique code data to the train detecting signal received from said control device on the ground and transmits the same to the track circuit;
wherein said receiver adds a second unique code data to the train detecting signal being added of the first unique code data received from the track circuit and transmits the same to said control device on the ground;
wherein said control device on the ground includes a storage portion and a collating portion which collates whether the first unique code data and the second unique code data received from said receiver coincide with data stored in advance in said storage portion; and
wherein said data stored in advance in said storage portion are data of said transmitters and receivers corresponding to the respective track circuits and all of the corresponding unique code data assigned to said respective transmitters and receivers.

Abstract
A train detection system includes transmitters receivers connected to a track circuit for transmitting and receiving a train detecting signal to and from the track circuit, and a control device on the ground, which transmits the train detecting signal to the transmitter and receives the train detection signal from the receiver. The transmitter adds a first unique code data to the train detecting signal received from the control device and transmits the same to the track circuit, and the receiver adds a second unique code data to the train detecting signal being added of the first unique code data received from the track circuit and transmits the same to the control device. The control device on the ground includes a storage portion and a collating portion which collates whether the first and second unique code data received from the receiver coincide with data stored in advance in the storage portion.
