[Embodiment 1] FIG. 1 shows the configuration of Embodiment 1 of the present invention.
This will be described with reference to FIG. FIG. 2 is a block diagram showing the entire remote monitoring system including the first embodiment of the present invention. A telephone line network (NTT subscriber telephone network) 2 and a monitoring center 3 are the same as those of the above-described conventional system.
FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention, and is the same as that of the above-described conventional device except for the computer 8A. In the drawings, the same reference numerals indicate the same or corresponding parts.

In FIG. 2, 1A is a remote monitoring device. In the present remote monitoring system, as shown in FIG. 2, the remote monitoring device 1A issues failure information to the monitoring center 3 through the telephone network 2 when an equipment failure occurs,
The computer of the monitoring center 3 receives the failure information and notifies the center staff that the equipment failure has occurred.

In FIG. 1, reference numeral 8A denotes a computer having a different function (program) from the conventional computer. The computer 8A of the remote monitoring device 1A detects, via the I / O interface 5, the state of the maintenance switch 4 and whether or not there is a facility monitoring input 12, and detects failure information via the modem 6 and the network control device 7. To the telephone network 2. In addition, the time of the periodic notification is counted by an internal software timer, and a periodic notification is issued to the monitoring center 3 once / day at intervals. The monitoring center 3 automatically monitors whether there is a once-a-day / one-day regular alert for each building, and outputs an alarm when there is no regular-alert,
Inform the center staff.

In the meantime, the maintenance switch according to the present invention corresponds to the maintenance switch 4 in the first embodiment of the present invention, and the periodic alarm processing means according to the first embodiment is the same as the first embodiment.
Is composed of an I / O interface 5, a modem 6, a network controller 7, and a computer 8A.

Next, the operation of the first embodiment will be described with reference to FIGS. FIG. 3 is a timing chart showing the operation of the first embodiment of the present invention. 3, (a) shows the maintenance switch 4, (b) shows the regular alarm time, (c) shows the regular alarm operation, and (d) shows the regular alarm check alarm operation of the monitoring center 3. FIG. 4 is a flowchart showing a periodic alarm program according to the first embodiment of the present invention.

In step 41, the remote monitoring device 1A
The computer 8A determines whether or not the regular alarm time shown in FIG. 3B has come. If it is not the regular alarm time, the process ends without doing anything. If it is the regular alarm time, the process proceeds to the next step 42.

In step 42, it is determined whether the maintenance switch 4 is ON. That is, it is determined whether or not the signal shown in FIG. 3A input through the I / O interface 5 is at a high level. If it is OFF, the process proceeds to step 44, and if it is ON, the process proceeds to the next step 43.

In step 43, since the maintenance switch 4 is in the ON state, the periodic alarming operation waits for various times, and then returns to step 42 again.

In step 44, a periodic alarm operation is performed. That is, as shown in FIG. 3C, the periodic alarm is issued immediately after the maintenance switch 4 is turned off.

The first embodiment of the present invention, as described above,
When the equipment inspection operator changes the maintenance switch 4 from ON to OFF, if the scheduled alarm time is reached during the ON state, a periodic alarm program is provided to issue a periodic alarm immediately after the maintenance switch 4 is turned OFF. Therefore, conventionally, the maintenance switch 4 is
In the state of N, all alarms are suppressed, and there are cases where regular alarms cannot be issued depending on the inspection time slot. However, by changing the timing of alarms as described above, the above cases can be saved. This has the effect.

That is, when the maintenance switch 4 of the remote monitoring device 1A is in the ON state shown in FIG. 3A and the time-counting alarm time shown in FIG. It waits for the operation, and after the maintenance switch 4 is turned off, issues a periodic notification to the monitoring center 3 via the I / O interface 5, the modem 6 and the network controller 7. This eliminates the periodic alarm check alarm performed by the monitoring center 3 and can prevent useless dispatch of the inspection operator.

There is also a method of issuing a periodic alarm when the maintenance switch 4 is in the ON state. In this case, after the equipment inspection is completed,
If the facility inspection operator forgets to turn off the maintenance switch 4, there is a disadvantage that all facility failures cannot be reported. This is because the regular alert is issued every day and the monitoring center 3 does not notice any abnormality. The monitoring center 3
Is performed, for example, once a day (24 hours).
