Abstract

PURPOSE:To collect an alarm signal from each exchange station in a short time at each supervisory board by providing a supervisory board controller corresponding to the supervisory board between a switching controller controlling an alarm link switching device and plural supervisory boards. CONSTITUTION:In a system where an alarm signal from plural exchange stations RT1-RTn are collected by plural supervisory boards SV1-SVm via an alarm link switching device SW, the supervisory board controllers SC1-SCm are provided between the switching controller SWC controlling the device SW and the supervisory boards SV1-SWm. The devices SC1-SCm receive the control state information of the device SW by the device SWC, transmits the connection control request between the exchange station and the supervisory board by the SW to the device SWC and allows each supervisory board to sequentially collect the alarm signal from each exchange station connected by the device SW. When the supervisory board corresponding to each device SC is connected to all the exchange stations, each device SC brings the supervisory board to the temporary stand-by state, acquires the exchange station of the idle link sequentially and independently to connect all the exchange station to the supervisory board.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an alarm polling method in which alarm signals from a plurality of exchanges installed in remote locations are collected by a plurality of monitoring stations of a monitoring station.

Prior Art and Problems In a switching system in which multiple switching stations are located in remote locations, alarm signals caused by failures at each switching station are collected at a monitoring station where a maintenance person is stationed.

If the monitoring station grasps the status of each exchange and determines that emergency recovery is necessary, maintenance personnel go to that exchange and perform the recovery process. There is. For example, as shown in FIG. 1, the monitoring station includes a plurality of monitoring stands SVI to SVm and an alarm link switching device SW.
and a switching control device SWC, and a plurality of switching stations RTI~
RTn and the plurality of monitoring stations SVI to SVm are connected via an alarm link switching device SW, and each switching station RT1 to
It is configured so that alarm signals of RTn can be collected by each monitoring stand SVI-3Vm.

In order to collect alarm signals from each exchange RTI to RTn on each monitoring stand svi to SVm, the alarm link switching device sw is controlled by a switching control device [SWC,
It is conceivable to sequentially connect ~RTn to the monitoring stand SVI-3Vm. In that case, RTI ~
Assuming that the RTs and monitoring stand are SVI to sv3, Fig. 2 (a
), switching center RTI and monitoring stand SV 1, switching center RT2 and monitoring stand SV2, switching center RT3 and monitoring stand SV3
As shown by the arrows, the alarm link switching device S
connected via W (not shown in FIG. 2),
After a predetermined time, as shown in FIG.
2 and the monitoring stand SV1, the exchange RT3 and the monitoring stand SV2, and the exchange RT4 and the monitoring stand SV3 are connected as shown by the arrows. Thereafter, monitoring stations SVI to SV3 are connected to the respective exchanges RTI to RT5 in the same manner.

The switching control device SWC performs control to sequentially connect the three monitoring stations SVI to SV3 to the switching stations RTI to RT5, and controls the alarm link switching device SW to perform connection switching at regular intervals. Therefore, if the control unit receives an alarm signal from relatively different parts, the monitoring stand SV2 requests detailed fault information from the switching station RT2, and the monitoring stand SV2 and the switching station RT2
The communication time will be longer. If this communication time becomes longer than a certain period, switching control of the alarm link switching device SW is performed, so it is necessary to wait until the next period to collect the remaining fault information.

Furthermore, until the communication between the monitoring stand sv2 and the switching station RT2 ends, a control signal is sent to the switching control device SWC to maintain the connection state at that point, and detailed failure information of the switching station RT2 is collected. The termination of the second connection state
It is also conceivable to shift to the state shown in FIG.

The collection of alarm signals by the above-mentioned sequential control is carried out at each switching station RTI on each monitoring stand sv1 to SV, m.
It is possible to collect all of the ~RTn alarm signals, but whether it is collected at regular intervals or by appointment,
The disadvantage is that the time required to collect alarm signals is longer.

Therefore, it is conceivable to perform skip control in which when a monitoring stand receives detailed failure information from an exchange, it connects to the next exchange without waiting for another monitoring stand. FIG. 3 fa) to tfl are explanatory diagrams of the skip control.
and switching center RT4 are connected, and at that point switching center RT3
When the alarm signal from the switching station SV2 is received by the monitoring station SV2, the monitoring station S2 performs an operation to receive detailed fault information from the exchange RT3. That is, the connection state between the monitoring stand SV2 and the switching center RT3 becomes longer. Therefore, as shown in (b), the connection between the monitoring stand SV2 and the switching station RT3 is left as is, the monitoring stand SVI is skipped and connected to the switching station RT4, and the monitoring stand SV3 is connected to the switching station RT5. be.

Next, as shown in the tel, the monitoring station SVI and the switching center RT4
, when the connection between the monitoring stand SV3 and the switching station RTI is established and the information transmission between the monitoring stand SV2 and the switching station RT3 is completed, the completion signal is transmitted to the switching control device SWC,
The switching control device SWC is capable of connecting the monitoring stand SV2 and the switching station RT4 by means of an alarm link switching device WSW.

Next, as shown at +dl, the monitoring station SVI and the switching center RT1
, the monitoring stand SV3 and the switching station RT2 are connected, and the monitoring stand SV2 and the switching station RT5 are connected. Next, as shown at +91, connections are made between the monitor S1 and the exchange RT2, between the monitor SV2 and the exchange RTI, and between the monitor SV3 and the exchange RT3. In this state, if there is a lot of information being transmitted from switching station RT3 to monitoring station SV3 and the connection duration is long, then as shown in ffl, the connection status between monitoring station SV3 and switching station RT3 is maintained, and the monitoring station SVI, switching center RT4, monitoring stand SV2
A connection is made between the exchange station RT2 and the exchange center RT2.

In the above case, the monitoring stand SVI will not be connected to the exchange RT3. In other words, when performing skip control, it is possible to collect alarm signals by having a monitoring station that remains connected for a long time connect to the next exchange without leaving other monitoring stations in a waiting state. However, the drawback is that some exchanges are unable to collect the alarm signal.

OBJECTS OF THE INVENTION It is an object of the present invention to enable alarm signals from each exchange to be collected in a relatively short time and alarm signals from all exchanges to be collected at each monitoring stand.

Structure of the Invention The present invention provides a maintenance intensive system in which alarm signals from a plurality of switching stations are collected by a plurality of monitoring stands via an alarm link switching device, and a switching control device that controls the alarm link switching device; A monitoring stand control device is provided between the monitoring stand and the monitoring stand corresponding to the monitoring stand, and the monitoring stand control device receives the control state information of the alarm link switching device by the switching control device, and performs control by the alarm link switching device. A request for connection control between the exchange and the monitoring station is sent to the switching control device, alarm signals from the exchanges connected by the alarm link switching device are collected by the monitoring station, and the monitoring station is connected to multiple exchanges. After all connections have been made, the monitoring console is put into a temporary standby state, and the monitoring console controller independently searches for an exchange with an empty link one after another and requests a connection between the surveillance console and the exchange. , a monitoring stand is connected to all exchanges. Examples will be described in detail below.

Embodiment of the Invention FIG. 4 is a block diagram of essential parts of an embodiment of the invention, in which the same reference numerals as in FIG. 1 indicate the same parts, and SC1 to SCm are monitoring stand control devices. The monitoring stand controllers SC1 to SCM are provided corresponding to the monitoring stands s■1 to svm, and each of the monitoring stand controllers SCI to SCm is an independently switching control bag. & SWC is inquired about the usage status of the alarm link switching device SW, a request for connection to the switching center of the vacant link that has not yet been connected is sent to the switching control device SWC, and the switching control device SW
C controls the alarm link switching device SW to connect the monitoring stand and the exchange in accordance with the connection request. The monitoring stand connected by the alarm link switching device SW requests information from the exchange, and if there is no alarm signal, the monitoring stand sends a signal for the next connection to the monitoring stand control device,
The monitoring console control device shifts to connection control for the next vacant exchange. When the monitoring stand receives an alarm signal, it requests detailed fault information from the exchange that sent the alarm signal, and upon completion of receiving the fault information, sends a reception end signal to the monitoring stand control device, which controls the monitoring stand. In response to the reception end signal, the device shifts to connection control to the next vacant exchange.

The monitoring console controllers SCI to SCm are equipped with a memory for storing the connected exchanges, and for example, exchanges R
Write the presence or absence of connection to the memory area corresponding to TI to RTn,
When it is determined that all exchanges RTI to RTn have been connected, the system enters a temporary standby state, clears the memory area, and after a predetermined period of time makes a connection request to an idle link exchange.

FIGS. 5(a) to lfl are explanatory diagrams of the operation of the embodiment of the present invention, in which 9 monitoring stand control devices SCI and SC2 are used in Ta+.
, SC3 inquires of the switching control device swc about the usage status of the alarm link switching device sw and requests connection, respectively, and the monitoring station SVI, the switching station RT2, and the monitoring station S
If V2 and switching station RT3 are connected, and monitoring station SV3 and switching station RT4 are connected, no alarm signal is received, and the monitoring station controllers SC1, SC2, and SC3 control the connection to the switching station of the next vacant link. (As shown in bl, the monitoring stand sv1, the exchange RT3, the monitoring stand Sv
2 and the switching station RT4, and the monitoring stand SV3 and the switching station RT5 are connected.

At this point, when the monitoring stand control device SC3 identifies that the monitoring stand SV3 is connected to the exchanges RTI to RT5, in the next cycle (as shown in C1), the monitoring stand SV3 goes into a temporary standby state, and the other monitoring stations The stand SVI is connected to the switching station RT4, and the monitoring stand SV2 is connected to the switching station RT5.At this point, when the monitoring stand control device SC2 identifies that the monitoring stand sv2 is connected to the switching stations RT1 to RT5, in the next cycle As shown in (d), the monitoring stand SV2 is in a temporary standby state, the other monitoring stand SVI is at the switching station RT5, and the monitoring stand SV3 is at the switching station R.
Connected to TI.

In the next cycle, as shown in
V3 is connected to switching station RT2, and in the next cycle, as shown at +fl, monitoring station SVI, switching station RT1, and monitoring station SV
2 and the switching center RT2, and the monitoring stand SV3 and the switching center RT3 are connected.

As mentioned above, if there is no alarm signal and the communication time between the monitoring station and the exchange is short, connections will be made sequentially, and the monitoring station connected to all exchanges will be connected to the next It goes into a temporary standby state periodically.

Also, in the state (al) shown in Fig. 5, if the monitoring stand SV2 receives an alarm signal from the switching station RT3, requests detailed fault information, and the communication time with the switching station RT3 becomes long. In this case, the monitoring stand SV3 is connected from the switching center RT4 to the switching center RT5.
When the connection is switched to , the monitoring platform controller SCI inquires the switching controller SWC about the next free link.
The switching control device SWC notifies the exchanges RTI and RT4 that the link is free. Therefore, the monitoring stand control device sci requests the switching control device SWC to form a link to the next switching station RT4, and a connection is established between the monitoring stand SVI and the switching station RT4.

That is, in (bl in FIG. 5), the monitoring stand shown in parentheses is in the connected state, and if only the symbols are used, RT3→(SV2
), RT4 → (SVI), RT5 → (SV3)
connection status.

In the next cycle, as shown in Figure 5 (C1), the monitoring platform (SV3) becomes temporarily on standby, and the monitoring platform (SVI)
is connected to the switching center RT5, and the monitoring stand (SV2) is connected to the switching center RT4 when communication with the switching center RT3 is completed. In this connected state, the monitoring stand (SVI),
If (SV2) did not receive the alarm signal, then 1
Next, as shown at +dl, the monitoring stand (SVI) becomes temporarily in a standby state, the monitoring stand (SV3) is connected to the switching center RTI, and the monitoring stand (SV2) is connected to the switching center RT5. Similarly, the monitoring stand (SV2) is next placed in a temporary standby state, and the monitoring stand (SVI) is connected to the switching center RT1, and the monitoring stand (SV3) is connected to the switching center RT2. In this connected state, if the monitoring stand (SVI) receives an alarm signal from the exchange RTI and requests detailed fault information, the monitoring stand SV3 will be connected to the exchange RT3 and the monitoring stand SV2 as shown in (fl).
is skipped and connected to exchange RT2.

Therefore, even if there are the same number of exchanges and monitoring stations, the monitoring station will be connected to all exchanges, and the communication time between the monitoring station and the exchange will be longer due to the reception of alarm signals. Even if this happens, each monitoring station will be connected to all exchanges.

As described in detail, the present invention provides a monitoring stand control device corresponding to the monitoring stand, and each monitoring stand control device independently inquires of the switching control device SWC about the usage status of the alarm link switching device SW, and A connection request is made to the link switching center to establish a connection between the monitoring board and the switching center. When the monitoring board is connected to all the switching centers, the monitoring board is placed on standby for a predetermined period of time, and detailed failure information is sent to the switching center. If this request increases the communication time with the exchange, the other monitors will be controlled to connect to the exchange with an empty link using skip control. Since connections are made to all exchanges, any monitoring stand can monitor all exchanges. Furthermore, since there are no waiting monitors except for the monitors that are temporarily on standby, each monitor can be connected to all exchanges in a relatively short time.
