6. A Study of a New Monitoring System tor Railway Signal Equipment usmg Radio Commumncation A monitoring system tor signal equipment has bcen in place for several years at the JR East Hence the state of signal eduipment at the maintenancc center is known But this system was installed over 20 years ago so it cannot meet the necds of stable operation broadband data transfer or casy construction and casy maintenance To satisfy these needs we selected the method using radio communication to realize the oucdoor operation along railroads In this studY terminals and repeaters based on the ZigBec protocol have been developed We used two different radio bands simulraneously Eventually good resulrs were achieved ZigBee 1 1 20
