Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an abnormality monitoring and reporting device that monitors abnormalities in a monitored object and notifies a monitoring source using a telephone line when a new abnormality occurs.

Even when a monitoring target side has a plurality of subscriber telephone lines, this type of conventional device is only connected to a specific line and cannot make a single report using an idle line.

Therefore, at the time an abnormality to be monitored is detected, if the phone on this specific line is in use, including incoming calls, or if this line is out of order, we will wait until these lines are restored before reporting. Furthermore, even if the monitoring source has multiple subscriber telephone lines, sometimes the specified line cannot be used (and sometimes the user has no choice but to wait for the line to be restored).

Thus, in the conventional abnormality monitoring and reporting device, since there is a delay in reporting, it is often impossible to quickly respond to abnormalities in the monitored object through monitoring, which may lead to a serious accident.

The present invention has been made to eliminate the above-mentioned drawbacks.
An object of the present invention is to provide an abnormality monitoring and reporting device that can extremely quickly report abnormalities in a monitored object by effectively utilizing a plurality of subscriber telephone lines.
