[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving device which is connected to a subscriber telephone line to receive anomaly notifications and regular data from a reporting device, and in particular, sets a priority for the telephone number of each reporting device. The present invention relates to a receiving device that enables interrupt notification of a notification device to which a high priority is assigned.

2. Description of the Related Art A conventional receiving device requires two sets of devices, one for receiving emergency calls from a plurality of reporting devices and the other for receiving regular data other than emergency calls. It is known that the subscriber telephone line is exclusively connected to the set.

[0003]

When an abnormality such as a fire or overflow of sewer is detected, an emergency call is sent from the notification device to the reception device via the subscriber telephone line. The frequency of occurrence of emergency calls is extremely low, and the frequency of use of the receiving device dedicated to emergency calls and the frequency of use of the subscriber telephone line to which the receiving device is connected are also extremely low.

On the other hand, the receiving device and the subscriber telephone line are required to receive the regular data other than the emergency call transmitted from the plurality of reporting devices. Therefore, the cost of the receiving device is increased and the subscriber telephone is used. There is a problem that leads to an increase in line usage charges.

By receiving the emergency call and the periodical data with one receiving device, the cost problem can be solved.
When an emergency call occurs while receiving regular data, the fatal problem of not being able to receive the emergency call occurs, and there is no point in installing a receiving device.

That is, even if the regular data is being received, if there is an emergency call, the problem can be solved by switching to the emergency call side so that the data can be received. Call waiting service is known as a service that can be interrupted by a third party during a call by two parties. If this service is used, hooking operation (for a short time without shutting down the subscriber telephone line even if another call occurs during a call) Hooking)
It is possible to switch the currently running notification to another notification.

However, when the currently executed report is an emergency report and the other reports are periodic data reports, switching the reports by the call waiting service causes inconvenience. Therefore, it is not necessary to simply switch the notification, but it is necessary to determine the priority (urgency) of the notification and switch to the notification with a higher priority.

The present invention has been made to solve the above problems, and its purpose is to compare the priorities of the currently executed message and the interrupted message when there is an interrupt during message reception. By prioritizing and receiving high-priority messages, it is possible to realize simplification of equipment and economy, and to provide a highly convenient receiving device.
