Patent ID: 6845127

Claim:
A real time remote monitoring system using an ADSL modem in a reverse direction, comprising: monitoring means for monitoring an object facility to be monitored; remotely monitored data processing means for monitoring motions according to each channel with respect to the monitored data obtained by the monitoring means so as to be compression-encoded and transmitted in a bit stream, and generating detection signals with respect to the monitored data that have been detected; first ADSL modulating/demodulating means installed in a reverse direction for modulating the data inputted from the remotely monitored data processing means so as to be upwardly transmitted to a network in a transmission velocity higher than that of a downward channel, and demodulating the data transferred from the network in a transmission velocity lower than that of an upward channel so as to be transferred to the remotely monitored data processing means; second ADSL modulating/demodulating means installed in a reverse direction for demodulating the data transferred from the first ADSL modulating/demodulating means in a transmission velocity higher than that of the downward channel so as to be transferred to a receiving party, and modulating the data transferred from the receiving party so as to downwardly transferred to the first ADSL modulating/demodulating means in a transmission velocity lower than that of the upward channel.
