Japanese Patent JP7164464
Kind Code:
B2
Abstract:
Radios used in conventional radio-type train control systems are often general-purpose machines usable in other industries and were not necessarily suitable in train control systems. For this reason, in the present invention, an on-board radio device has an antenna part (306) for transmitting and receiving signals to and from outside a train, a radio body device (304) for communicating signals with the antenna part, and a signal cable (305) connecting the antenna part and the radio body device, the antenna part being provided with at least an antenna circuit (309), an RF circuit (308) connected to the antenna circuit, and a programmable logic device (311) connected to the RF circuit.
