Description

  The present invention relates to an alarm monitoring system that manages an alarm from a monitoring device.

  For example, as an alarm output at the time of power system failure or abnormality occurring on the input / output device side, detection of changes in SV information and TM information indicating the state of the power system input from the remote monitoring control device, There is one in which it is determined whether or not the detected change is due to a failure or abnormality in the power system, and an alarm output is notified based on the obtained determination result (for example, see Patent Document 1). .

  FIG. 4 is a configuration diagram of a conventional alarm monitoring system. In FIG. 4, measurement points 100 and 200 include monitoring and measuring means 101 and 201 and alarm transmission means 102 and 202. The alarm sending means 102 and 202 issue an alarm according to the measured values of the monitoring and measuring means 101 and 201, and call the local general management office 300 or 400 via the external telephone lines 601 and 602 to transmit the alarm signal. . The regional general management offices 300 and 400 include modems 304 and 404, display operation means 302 and 402, and routers 303 and 403.

  Here, in FIG. 4, one monitoring and measuring means 101 and 201 are shown for the measuring points 100 and 200, respectively, and one measuring point 100 and 200 is connected to the regional general management offices 300 and 400, respectively. However, one measurement point 100, 200 has one or more monitoring measurement means 101, 201, and one regional general management office 300, 400 has one or more measurement points 100, 200 as management targets. The regional general management offices 300 and 400 are connected to the central monitoring station 500 via an intranet 603.

If the monitoring and measuring means 101 at the measuring point 100 senses an abnormal value, the alarm sending means 102 issues an alarm signal and calls the regional general management office 300. The alarm signal is transmitted to the regional general management office 300 through the external telephone line 601. In the regional general management office 300, the alarm signal transmitted through the external telephone line 601 is received by the modem 304. Then, the alarm signal is immediately transmitted to the router 303 and the alarm signal is transmitted to the intranet 603. Eventually, alarm signals are collected at the central monitoring station 500, where they are collectively managed. The measurement point 200 is also transmitted to the central monitoring station 500 through the regional supervision management station 400 in the same manner. Each regional management office 300, 400 does not have a function of storing an alarm signal, but has simple display operation means 302, 402 having a function of displaying an alarm signal.
JP-A-11-32448

  However, in the conventional alarm monitoring system, a simple display operation means 302, 402 can be installed in the regional general management office 300 to display the alarm signal, but the transmitted alarm signal is stored. Is not provided. That is, the alarm signal received by the modems 304 and 404 must be transferred to the routers 303 and 403 immediately. Therefore, when there is an abnormality in the intranet 603 and transmission to the central monitoring station 500 is impossible, there is no transfer destination even if the alarm signal is received, and the alarm signal may be discarded.

  An object of the present invention is to provide an alarm monitoring system that can reliably transmit an alarm signal emitted from a measurement point to a central monitoring station without loss.

  The alarm monitoring system of the present invention includes a measurement point that measures a process amount and transmits an alarm, a regional general management office that supervises the measurement points in units of regions, a central monitoring station that centrally manages all measurement points, and measurement points. In the alarm monitoring system comprising an external telephone line connecting the regional control center and the intranet connecting the regional control center and the central monitoring station, the measurement point is monitored based on the process amount of the measurement point The monitoring and measuring means for performing the determination, the alarm is judged based on the result from the monitoring and measuring means, and when it is an alarm, the external telephone line is connected to the telephone number of the regional management office in charge and connected to the telephone number. When it is not possible, it has an alarm transmission means for automatically switching and connecting to a telephone number of another regional management office registered in advance, and the regional management office is connected to the intranet And a receiving adapter for connecting to the external telephone line and monitoring the status of the router and automatically disabling the external telephone line due to an abnormal signal of the router, To do.

  According to the present invention, even when an alarm signal cannot be transmitted from the regional headquarters to the central monitoring station, it is possible to switch to another route on the measurement point side and reliably transmit the alarm signal to the central monitoring station. .

  Hereinafter, an alarm monitoring system according to an embodiment of the present invention will be described. FIG. 1 is a block diagram of an alarm monitoring system according to the first embodiment of the present invention. This first embodiment is different from the conventional example shown in FIG. 4 in that receiving adapters 301 and 401 are provided instead of the modems 304 and 404, and the alarm transmission means 102 at the measuring point 100 is connected to the external telephone line 602. And a connection line 12 connected from the alarm transmission means 202 at the measurement point 200 to the external telephone line 601 is provided. When alarm information is generated at the measuring point 100, the external telephone line 601 is used to connect to the telephone number of the regional management office 300 having jurisdiction. When the telephone number cannot be connected, another area registered in advance is connected. The telephone number of the general management office 400 is automatically switched and connected via the connection line 11 and the external telephone line 602. Similarly, when alarm information is generated at the measuring point 200, it is connected to the telephone number of the regional management office 400 having jurisdiction over the external telephone line 602, and when it cannot be connected to that telephone number, The telephone number of the regional general management office 300 is automatically switched and connected by the connection line 12 and the external telephone line 601.

  The measuring points 100 and 200 have monitoring and measuring means 101 and 201 and alarm transmitting means 102 and 202. The alarm transmitting means 102 and 202 issue an alarm according to the measured values of the monitoring measuring means 101 and 201, and the regional headquarters Calls 300 and 400 to transmit an alarm signal. In FIG. 1, the measurement points 100 and 200 each have one monitoring measurement means 101 and 201, but usually one measurement point 100 and 200 has one or more monitoring measurement means. In addition, the regional general management offices 300 and 400 each indicate one measurement point 100 or 200 as a management target. However, one regional general management office normally has one or more measurement points as management targets. .

  In addition, the telephone from the measuring point 100 can be called not only to the regional management office 300 in charge but also to the backup regional management office 400. In the case of “busy”, an abnormality in the external telephone line 601 or the like. If the external telephone line 601 with the regional general management office 300 is not connected due to the above reasons, the local general management office 400 is automatically called. The alarm transmission means 102 has a function for that purpose.

  Now, assuming that the monitoring and measuring means 101 senses an abnormal value, the warning sending means 102 issues a warning signal and calls the regional general management office 300. The alarm signal is transmitted to the regional general management office 300 through the external telephone line 601. In the regional supervision office 300, the alarm signal transmitted through the external telephone line 601 is received by the reception adapter 301. Then, the alarm signal is immediately transmitted to the router 303 and the alarm signal is transmitted to the intranet 603. Eventually, alarm signals are collected at the central monitoring station 500 and managed there.

  Here, the receiving adapter 301 constantly monitors the state of the router 303. If transmission to the central monitoring station 500 is not possible, such as when there is an abnormality in the intranet 603 or when there is an abnormality in the router 303 itself, there is a risk that the alarm signal will be discarded because there is no forwarding destination even if an alarm signal is received. So to avoid it.

  The router 303 issues an abnormality signal when the intranet 603 becomes abnormal or when it becomes abnormal. That is, the router 303 constantly monitors the state of the intranet 603, and when an abnormality of the intranet 603 is detected, the router 303 issues an abnormality signal. When the receiving adapter 301 senses an abnormal signal of the router 303 or senses an abnormality of the router 303 itself, it automatically disconnects the connection with the external telephone line 601 and rejects the connection even if there is a call from the measuring point 100 The reception of the alarm signal is blocked.

  In this state, the alarm signal from the measurement point 100 is not transmitted to the central monitoring station 500. Therefore, while reception of the alarm signal at the regional supervision management station 300 is blocked, the alarm signal from the measurement point 100 is transmitted as an alarm transmission means. A call is made to another regional management center 400 set in 102, and an alarm signal is transmitted to the central monitoring station 500 via the regional management center 400.

  When the router 303 detects the normal return of the intranet 603, the router 303 stops sending the abnormal signal. Then, the reception adapter 301 does not sense the abnormal signal of the router 303, and if the router 303 itself determines that there is no abnormality, the reception adapter 301 automatically restarts the connection with the external telephone line 601, and calls from the measuring point 100 to the telephone. When there is, the alarm signal reception is resumed. An alarm signal from the measurement point 100 is transmitted to the central monitoring station 500 via the regional management center 300. The alarm signal from the measurement point 200 is also transmitted to the central monitoring station 500 in the same way via the regional management office 400 in the normal state and through the backup regional management center 300 in the abnormal state.

  According to the first embodiment, when alarm information is generated, an external telephone line is used to connect to the telephone number of the regional headquarters in charge. Automatically switch to the telephone number of the regional headquarters in the country, and even if the alarm signal cannot be transmitted from the regional headquarters to the central monitoring station, it will surely reach the central monitoring station through another route from the measuring point side An alarm signal can be transmitted.

  Next, a second embodiment of the present invention will be described. FIG. 2 is a block diagram of an alarm monitoring system according to the second embodiment of the present invention. This second embodiment is provided with a connection line 13 for connecting external telephone lines 601 and 602 to the first embodiment shown in FIG. Instead of automatically disabling the external telephone lines 601 and 602 due to an abnormal signal of the routers 303 and 304, the received alarm signal is automatically transferred to another regional management office through the external telephone lines 601 and 602. It is what you do. When the alarm signal cannot be transmitted from the regional management center 300 to the central monitoring station 500, the regional management center 300 itself calls another regional management station 400 and passes through another regional management center 400. The data is transmitted to the central monitoring station 500.

  That is, the reception adapter 301 constantly monitors the state of the router 303. The router 303 constantly monitors the state of the intranet 603. When the router 303 detects an abnormality of the intranet 603, the router 303 issues an abnormality signal. When the reception adapter 301 senses an abnormal signal of the router 303 or an abnormality of the router 303 itself, the reception adapter 301 automatically calls itself to the regional general administration office 400 when receiving the alarm signal. Change the settings.

  If an alarm signal is received while connection to the intranet 603 is not possible, the reception adapter 301 temporarily stores the alarm signal in itself and disconnects the telephone line with the measuring point 100. After that, the reception adapter 301 calls the backup area general management office 400. When the external telephone lines 601 and 602 are connected, the alarm signal is sent from the reception adapter 301 to the reception adapter 401 of the backup area general management office 400 via the external telephone lines 601 and 602 and sent to the central area via the backup area general management office 400. An alarm signal is transmitted to the monitoring station 500.

  When the router 303 detects that the intranet 603 has returned to normal, the router 303 stops sending an abnormal signal. If the reception adapter 301 does not sense the abnormality signal of the router 303 and determines that the router 303 itself has no abnormality, the reception adapter 301 returns the connection setting to the original setting. The received alarm signal is transmitted to the central monitoring station 500 through the router 303 of the regional supervision office 300. In this case, the receiving adapter 301 needs to be compatible with a plurality of external telephone lines (for receiving from a measuring point and for inter-regional management offices) and receiving another warning signal after receiving an alarm signal. A function for temporarily storing the alarm signal is required until it is transferred to the management office. The alarm signal from the measuring point 200 is also transmitted in the same manner, only through the regional management office 400 in the normal state when it is normal, and via the regional management center 400 and the backup regional management center 300 in the abnormal state. It is transmitted to the central monitoring station 500.

  According to the second embodiment, even if an alarm signal cannot be transmitted from the regional headquarters to the central monitoring station, the local headquarters office switches to another route and reliably transmits the alarm signal to the central monitoring station. Is possible.

  Next, a third embodiment of the present invention will be described. FIG. 3 is a block diagram of an alarm monitoring system according to the third embodiment of the present invention. In the third embodiment, the reception adapters 301 and 401 of the regional management office received the external telephone lines 601 and 602 instead of automatically disabling the connection by the abnormal signal of the routers 303 and 304. The alarm signal is temporarily accumulated, and the alarm signal temporarily accumulated by the return of the abnormal signal of the routers 303 and 304 is collectively transmitted to the central monitoring station 500 via the intranet 603. In FIG. 3, the measurement point 200, the external telephone line 602, and the regional general management office 400 are not shown.

  In FIG. 3, the receiving adapter 301 constantly monitors the state of the router 303. At the same time, the reception adapter 301 temporarily stores the received alarm signal in itself. The router 303 constantly monitors the state of the intranet 603. When the router 303 detects an abnormality of the intranet 603, the router 303 issues an abnormality signal. The reception adapter 301 senses an abnormal signal of the router 303 or stops the transfer to the router 303 when it senses an abnormality of the router 303 itself. During this time, the alarm signal is accumulated in the reception adapter 301.

  When the router 303 detects the normal return of the intranet 603, the router 303 stops sending the abnormal signal. When the receiving adapter 301 no longer senses the abnormal signal of the router 303, it determines that the router 303 itself is normal. Then, the alarm signal accumulated in the receiving adapter 301 is transmitted to the central monitoring station 500 in a lump after the transfer to the router 303 is stopped and returned. Thereafter, the receiving adapter 301 returns the alarm signal to the central monitoring station 500 by itself as before. Note that the alarm signal from the measurement point 200 (not shown) is also stored in the receiving adapter 401 in the same manner when the intranet 603 is abnormal, and is transmitted to the central monitoring station 500 in a batch after returning. .

  According to the third embodiment, even if an alarm signal cannot be transmitted from the regional management office to the central monitoring station, it can be reliably stored in the central office even if transmission is impossible by temporarily storing it at the regional management office side. An alarm signal can be transmitted to a monitoring station.

  Here, a system with higher reliability can be obtained by combining two or more of the first embodiment, the second embodiment, and the third embodiment. In addition, the method described in each embodiment described above can be applied to various apparatuses as a program that can be executed by a computer, for example, written in a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or a communication medium. It is also possible to transmit by using and apply to various devices. A computer that implements this apparatus reads the program recorded on the recording medium, and executes the above-described processing by controlling the operation by this program.
