When the first table unit 22 manages the management data, the monitoring device 2 adopts a configuration that does not include the second table unit 23.

The first table means 22 of this embodiment comprises:
It manages the correspondence between the alarm patterns detected by the failure detection means 11 of the control device 1 and the failure identification information of the packages A0 to C1, and enables the alarm patterns and the switching instruction for the packages A0 to C1. A configuration for managing the correspondence with the switching control information indicating the presence or absence of sex is adopted. For example, "(0 0 0 0 0 0 0 0 0 01 0 0 0) indicates that only the failure detection means 11 (11) out of the failure detection means 11 (1) to (14) detects the failure mode.
For the alarm pattern ")", failure specifying information "(01010000)" indicating that the package B0 of the packages A0 to C1 is in a failure state is managed, and the packages C0 and C1 are managed. Switching control information “(0
0 1 1) "is managed.

When the first table means 22 for managing the data shown in FIG. 3 is provided, the monitoring device 2

The failure identification information of the packages A0 to C1 is read, and the switching control information indicating whether or not there is a possibility of a switching instruction for the packages A0 to C1 is read.

Subsequently, the package 10 in the fault state is specified according to the read fault specifying information. Subsequently, according to the read switching control information, the package 10 indicating the possibility of the switching instruction (the preceding package 10 of the package 10 is always in a failure state) is specified, and the specified package 10 is specified. Of the active system is the package 10 located at the previous stage of the current system.
In the case of, the possibility of the switching instruction is determined as the switching instruction. On the other hand, in the case of the standby failure package 10, the possibility of the switching instruction is changed to "no". It is determined that there is no switching instruction.

In this way, for example, the failure detecting means 1
1 generates an alarm pattern “(0 0 0 0 0 0 0 0 0 0 1 00 0)”, the failure identification information “(” indicating from the first table means 22 that the package B0 is in a failure state. 0 0 1 00 0) ”and switching control information“ (0 0 1 1) ”indicating that there is a possibility of changing the connection destination of the packages C0 and C1. Then, if the package B0, which is the faulty package 10 at the previous stage of the packages C0 and C1, is an active system,
By setting the switching control information to “(0 0 1 1)”, the switching units 12C0, 12C of the packages C0, C1 are set.
1 is determined, and on the other hand, if the package B0 is the standby system, the switching control information is set to “(0 00 00)”.
Is set, the switching means 1 of the packages C0 and C1 is set.
A non-switching instruction is determined for 2C0 and 12C1.

When the monitoring device 2 determines the switching instruction / non-switching instruction, the monitoring device 2 instructs the switching means 12 of the package 10 of the switching instruction destination to switch the connection in accordance with the determination, thereby causing the system down. Execute the fault control process to prevent.

As described above, when the first table means 22 manages the management data shown in FIG. 3, when a failure occurs in the control device 1, it is possible to immediately identify which package 10 has a failure. , Each package 1
The switching mode of the switching unit 12 of 0 can be determined, and the system can be quickly prevented from going down.

FIG. 4 shows an embodiment of the management data of the first table means 22 / second table means 23 provided in the monitoring device 2. Here, the data shown in FIG. 4A is an example of the management data of the first table means 22, and the data shown in FIG. 4C is an example of the management data of the second table means 23. It is.

In the embodiment shown in FIG. 3, the first table means 2
2 adopts a configuration in which the failure identification information and the switching control information are managed integrally, whereas in this embodiment, the first
4A, an alarm pattern generated by the control device 1 and a package A0 as shown in FIG.
4C, while the second table means 23 stores the failure identification information of the packages A0 to C1 and the package A0 as shown in FIG. 4C.
To C1 for managing the correspondence with the switching control information.

At the time of adopting this table configuration, the monitoring device 2 is provided with the failure detecting means (1) to (14) of the control device 1.
When an alarm occurs, the alarm pattern is first collected. Next, the fault identification information of the packages A0 to C1 is read out by searching the first table means 22 using the collected alarm pattern as a search address. Subsequently, the failure identification information read from the first table means 22 and the package A shown in FIG.
0 to C1 operation mode (“1” is set for the active package 10 and “0” is set for the standby package 10)
By performing a logical AND operation corresponding to bits with the above, the failure identification information read from the first table means 22 is changed.

Subsequently, the switching control information for the packages A0 to C1 is read out by searching the second table means 23 using the changed failure specifying information as a search address, and reading the switching control information for the packages A0 to C1. Switching instruction /
A non-switching instruction is determined. Then, in accordance with this determination, by instructing the switching means 12 of the packages A0 to C1 of the switching instruction destination to switch the connection, a failure control process for preventing a system down is executed.

As described above, for example, the failure detecting means 1
2 generates an alarm pattern “(0 0 0 0 0 0 0 0 0 0 1 00 0)”, the failure identification information “(” indicating from the first table means 22 that the package B0 is in a failure state. 0 0 1 00 0) ”is read. Subsequently, when the operation mode of the packages A0 to C1 at this time is “(101010)”, the read failure identification information “(01010000)” is changed to “(010010000).
"(There is no change in this case) according to the mode of canceling the standby package 10.
In accordance with the changed failure identification information “(0 0 1 0 0 0)”, the switching control information “(0 0 1 1)” indicating the switching instruction / non-switching instruction is read out from the second table means 22, and the package is read out. Switching means 12C0, 12C for C0, C1
By instructing the switching to 1, a failure control process for preventing the system from going down is executed.

As described above, when the first table means 22 / second table means 23 manage the management data shown in FIG. 4, when a failure occurs in the control device 1, only the table search process is performed to determine which package 10 Is determined to be a failure, the switching mode of the switching means 12 of each package 10 can be determined, and the system can be quickly prevented from going down.

In the table configuration shown in FIGS. 3 and 4,
If the package configuration of the control device 1 becomes complicated, the number of alarm patterns increases, and the table size becomes large, which causes a problem of lack of practicality.

To cope with this, the alarm patterns managed in the table are limited to those having a high probability of occurrence.
It is also an effective method to keep the table size practical. For example, when the control device 1 adopts the device configuration as shown in FIG.
Table means 22 / second table means 2 corresponding to 14 points (1) to (14).
3, the number of entries is originally “2 ¹⁴ = 16384”. However, if the alarm patterns generated by the packages C0 and C1 are limited to the seven patterns shown in FIG.
That is to say, it is possible to greatly reduce the value to "7 ² × 2 ⁴ = 784".

As another method for reducing the table size, the first table means 22 / the second table means 23 are prepared as one group of one or a plurality of packages and this group is prepared as a unit. It is also an effective method to adopt a configuration that goes through. When this configuration is adopted, for example, as shown in FIG. 7, the first table means 22 / the second table means 23 are provided in units of packages B0 and B1.
Is adopted, the first table means 2
2 / Management data of the second table means 23 is shown in FIG.
As shown in (b), the table size can be greatly reduced by reducing the number of alarm patterns.

In FIG. 8, when A0 to D1 are reception interface packages, E0 to F1 are multiplexing packages, G0 and G1 are switch packages, H0 to I1 are separation packages, and J0 to M1 are transmission interface packages. By grouping the input ports or output ports of the switch packages G0 and G1 and having a table for each group as indicated by a dotted line, the total amount of tables can be reduced without significantly impairing the fault identification capability. .

Here, when adopting a configuration in which the first table means 22 / the second table means 23 are prepared for each group of the package 10, a switching instruction signal to the upper package 10 is used. Since the failure state display of the lower package 10 may change, the failure state display is selected from the first table unit 22 / second table unit 23 prepared in association with the upper package 10 in order. It is preferable to perform processing so as to execute the failure control processing.

[0045]

As described above, according to the present invention,
In a control system including a control device including a package having a duplex confounding configuration and a monitoring device for performing a fault control process of the control device, when a control device generates an alarm, any package is immediately determined. In addition to being able to specify whether a failure has occurred, since the switching mode of each package can be determined, even when various types of failures occur due to an increase in the number of stages of the duplex confounding configuration, quick switching is possible. Thus, the failure control process can be executed in the first place.
