Abstract

PURPOSE: To inform an operator who is not present in a master station of the occurrence of situation change in a slave station. CONSTITUTION: At the time of receiving monitor information informed from a slave station 3 through a master station 2, a situation change receiving part 10 in a display processing part 1 displays the information 100 on a display part 4 through a display control part 11 only when a situation change occurs in the information 100. At the time of judging that the situation change of the information 100 received from the slave station 3 is a fault situation change, the receiving part 10 informs a radio pager communication control part 12 of the judged result. The control part 12 outputs a ringing request to a radio pager 5, converts the fault situation change into character information while referring to a fault situation information converting table 13 and adds the character information to the ringing request to the pocket bell 5 to send them. The pager 5 is driven to ring in response to the ringing request and displays the character information applied from the control part 12 on a display part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring system, and more particularly to a method for notifying an operator of a status change of monitoring information of a plurality of slave stations.

[0002]

2. Description of the Related Art Conventionally, in a remote monitoring system, when a master station is notified of a status change (hereinafter referred to as a status change) of monitoring information of each of a plurality of slave stations, an alarm of the status change is issued. , The change is only displayed on the display of the master station.

However, this method cannot notify the operator immediately of the change in the absence of the operator, which may delay the failure recovery. Therefore, there is a method in which, when an abnormal condition occurs when the operator is absent, an alarm is given by ringing the pager possessed by the operator when the abnormal condition occurs. This method is described in JP-A-1-
It is described in detail in Japanese Patent No. 221097.

[0004]

In the above-mentioned conventional remote monitoring system, when an abnormal condition occurs, the occurrence of the abnormal condition is displayed only on the display unit of the master station, or the pager carried by the operator is rung. Since the alarm is notified by doing so, it is not possible to immediately notify the operator what kind of situation has occurred.

Therefore, an object of the present invention is to solve the above problems and provide a remote monitoring system capable of notifying an operator who is not a master station of what kind of change has occurred in a slave station. is there.

[0006]

A remote monitoring system according to the present invention detects a monitored station having a function of transmitting monitoring information of its own station and a change in the status of the monitoring information transmitted from the monitored station. A remote monitoring system consisting of a monitoring station for displaying, the determining means for determining whether or not the state change is caused by a failure, and the determining means determines that the state change is due to the occurrence of a failure. A pager that is set in advance is sometimes provided with means for notifying the occurrence of the failure by text information.

In another remote monitoring system according to the present invention, in addition to the above configuration, a storage means for storing the contents of the fault and character information indicating the contents in association with each other, and the judging means for changing the state are When it is determined that a failure has occurred, the character information corresponding to the failure is read from the storage means.

[0008]

When the status change receiving unit of the display processing unit determines that the status change notification from the slave station received via the master station is a failure status change,
The failure condition is displayed on the display unit via the display control unit, and the pager communication control unit creates character information corresponding to the failure condition based on the contents of the failure condition conversion table. Is added to the ringing request for the pager and transmitted.

[0009] With this, even when the operator is absent in the master station, it is possible to notify the operator of what kind of change has occurred in the slave station.

[0010]

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, the display processing unit 1 displays the monitor information 100 notified from the slave station 3 via the master station 2 on the display unit 4, and the state change (hereinafter, referred to as state change) of the monitor information 100 is displayed. If it is a state change due to a fault (hereinafter referred to as a fault state change), the fault state change is notified to the pager 5 by character information.

When the state change receiving section 10 of the display processing section 1 receives the monitoring information 100 notified from the slave station 3 via the master station 2, if the state change occurs in the monitoring information 100, the display control section. It is displayed on the display unit 4 through 11. In this case, the display control unit 11 displays the state change received from the state change reception unit 10 on the display unit 4 and issues an alarm of the state change.

Further, the state change receiving unit 10 determines whether the state change of the monitoring information 100 from the slave station 3 is a fault state change, and if it is a fault state, notifies the pager communication control unit 12. The pager communication control unit 12 outputs a ringing request to the pager 5, converts the trouble condition into character information by referring to the trouble condition conversion table 13, and sounds the character information to the pager 5. Add to request and send.

Therefore, the pager 5 rings in response to a ringing request from the pager communication control section 12, and the pager communication control section 12 is displayed on the display section (not shown).
Display textual information from.

FIG. 2 is a diagram showing the configuration of the fault condition conversion table 13 of FIG. In the figure, the fault condition conversion table 13 stores preset character information for each content of fault condition.

For example, in the case of a remote monitoring system for a transmission line, character information "0000010" is stored in the fault state change conversion table 13 in correspondence with a fault state "transmission line disconnection".
Character information "00"
“00011” is stored in advance with the character information “0000012” corresponding to the failure condition of “switch abnormality”.

FIG. 3 is a flow chart showing the operation of notifying a fault condition according to an embodiment of the present invention. A fault condition notification operation according to an embodiment of the present invention will be described with reference to FIGS.

Upon receiving the monitoring information 100 notified from the slave station 3 via the master station 2, the status change receiving section 10 of the display processing section 1 determines whether the monitoring information 100 includes a status change notification. (FIG. 3 step S1).

If there is a state change notification, the state change reception unit 10 determines whether or not the state change notification is a fault state change (step S in FIG. 3).
2). If there is no fault, the state change receiving unit 10 displays the state change notification on the display unit 4 through the display control unit 11 (step S5 in FIG. 3). In this case, the display control unit 11 displays the state change notification received from the state change reception unit 10 on the display unit 4 and issues an alarm of the state change.

On the other hand, if the abnormal condition is received, the abnormal condition receiving unit 10 issues an alarm of the abnormal condition and displays the abnormal condition on the display unit 4 through the display control unit 11 (step S3 in FIG. 3). , And notifies the pager communication control unit 12 of the failure condition.

The pager communication control unit 12 refers to the fault condition conversion table 13 to convert the fault condition into character information, adds the character information to the ringing request to the pager 5, and sends it to the pager 5. Yes (step S in FIG. 3)
4).

Therefore, the pager 5 sounds in response to the ringing request from the pager communication control unit 12 and displays the character information from the pager communication control unit 12 on the display unit, so that the operator can display the display unit 4 The operator can be notified of the details of the failure even before the event, and the failure can be immediately dealt with even at night or on holidays, and the failure can be recovered.

For example, if the switch is out of order, the pager 5 displays "000001".
Since "2" is displayed, the operator can immediately know that a failure has occurred in the exchange, and can immediately go to repair the exchange.

In the above description, the case where there is one slave station 3 has been described, but it is obvious that the present invention is also applicable when there are a plurality of slave stations 3. In that case, if character information corresponding to the failure condition is set in the failure condition conversion table 13 for each slave station 3, the operator can know the failure occurrence location and the failure content.

Even when the notification of the status change from the slave station 3 is not a failure status change, if a table for converting the status change notification into character information is used similarly to the failure status change conversion table 13, the failure status change notification is used. It is also possible to notify the operator of a status change notification other than the above.

As described above, when the state change receiving unit 10 determines that the state change notification from the slave station 3 is a fault state change, the pager communication control unit 12 uses the contents of the fault state change conversion table 13 as a basis. By adding the created character information to the ringing request for the pager 5 and sending it, it is possible to notify an operator who is not in the master station of what kind of change has occurred in the slave station 3.

[0027]

As described above, according to the present invention, the state change notified from the monitored station having the function of transmitting the monitoring information of its own station is preset when it is determined that a failure has occurred. By notifying the pager of the occurrence of the failure by using the character information, it is possible to notify the operator who is not the master station of what kind of change has occurred in the slave station.
