To monitor the state of a remote monitor station at a center monitor station by resetting a body control part and automatically restarting the whole system if a line interface control part detects abnormality of the body control part, and informing the center monitor station of normalcy when the normalcy is confirmed.
The remote monitor station 3 is provided with the line interface control part 4 and the body control part 5 which controls the line interface part 4, and a 1st polling monitor part 6 of the line interface control part 4 and a 2nd polling monitor part 7 of the body control part 5 while sending and receiving polling signals to each other to monitor the operation states of the opposite parts 4 and 5. When the line interface control part 4 detects abnormality of the body control part 5, the body control part 5 is reset and the whole system is restarted; when the normal operation of the body control part 5 is confirmed after the resetting, its normalcy is reported to the center monitor station 1.
