Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure notification method, and more particularly to a failure monitoring method for centrally monitoring the device status of a communication processing system including a plurality of devices.

[Conventional technology]

Conventionally, in a communication processing system composed of a plurality of devices, in order to centrally monitor the failure of the devices constituting the system, a signal line is drawn from each monitored device to the monitoring device,
Collecting information about failures. Ie power supply, fan,
When a fuse has an abnormality detection circuit and detects an abnormality, the voltage of the signal line is changed to notify the abnormality. The signal lines are assembled on a frame-by-frame basis, housed in a single cable, and transported to the monitoring device. In the monitoring device, each signal line was taken out from the cable, and the voltage change was detected via the relay, and the lamp of the corresponding device on the display panel was turned on.

When designing such a system, it is necessary to determine the maximum configuration of the system and design a monitoring device having a receiving terminal of the monitoring device that matches the maximum configuration. In a device such as a switchboard, this method is sufficient because additional components are determined at the time of design, but it is composed of a storage device, a line system device, a media conversion system device, etc., like a communication processing device, depending on the traffic characteristics. In a system in which the configuration ratio changes and individual functional devices are added one by one each time a function is added, it is difficult to determine these configurations when designing the monitoring device, and it is possible to design the monitoring device with the maximum configuration. Can not.

[Problems to be solved by the invention]

The above-mentioned conventional technique has a problem that when the system is expanded, the capacity of the receiving device of the signal line of the monitoring device may be limited.

An object of the present invention is to solve such a conventional problem and to provide a failure notification system capable of collecting failure information of a monitoring target apparatus in the monitoring apparatus without restricting a change in system configuration.

[Means for solving problems]

In order to solve the above problems, the fault notification system of the present invention is a fault monitoring system having a monitoring device for centrally monitoring individual device states of at least one or more monitoring target devices. At least one supervisory signal relay device is provided between the two, and the supervisory signal relay device and the supervisory device are connected by a bus, and the monitored device notifies the supervisory signal relay device of the device state. And a means for notifying the monitoring device of the state of the monitored device from the monitoring signal relay device, and when the monitoring signal relay device detects a state change of the monitoring target device, asynchronously via the bus. It is characterized by notifying the monitoring device. Further, in the fault notification method, a device connected to the bus and having a unique function and a supervisory signal relay device are combined.

[Action]

In the present invention, the state of the monitored device is pulled into the monitoring signal relay device, and when the monitoring signal relay device detects a failure, the monitoring device is notified via the bus. As a result, the system can be changed with flexibility.

In FIG. 2, 6 is a processor and memory circuit that edits failure information, 7 is a system bus interface circuit, 8 is a failure acceptance circuit that accepts failures of the monitored device 4, and 9 is a processor bus that connects these circuits. Is.

FIG. 3 is a diagram showing a configuration example of the monitoring device 1 in FIG.

In FIG. 3, 10 is a processor and memory circuit for determining device failure and controlling the display circuit 12, 11 is a system bus interface circuit, 12 is a display circuit for displaying failure information, and 13 is these circuits. It is a processor bus. The operation of this embodiment will be described below with reference to FIGS.

Taking a fan as an example of the monitored device 4, when the fan stops due to a failure, a stop signal is transmitted to the failure reception circuit 8 of the monitoring signal relay device 3 through the signal line 5.
The failure acceptance circuit 8 reports an interrupt to the processor and the memory circuit 6, and the supervisory signal relay device 3 knows that the monitored device 4 has failed. Therefore, the supervisory signal relay device 3 edits the failure information and notifies the supervisory device 1 via the system bus interface circuit 7 and the system bus 2. The monitoring device 1 can know from the information from the monitoring signal relay device 3 and the system configuration that the monitored device 4, which has an interface with the monitoring signal relay device 3, that is, the fan has failed.
The operation of the monitoring device 1 will be described in more detail. When the system bus interface circuit 11 receives the failure information from the supervisory signal relay device 3, it reports an interrupt to the processor and memory circuit 10. The processor and memory circuit 10 analyzes the content of the received signal and determines which monitored device has a fault. When the determination is completed, a command is issued to the display circuit 12 and the alarm lamp of the relevant device is turned on.
The display circuit 12 may be a display, and in that case, the screen is edited to display a failure of the corresponding device.

In this way, the monitoring device 1 can collect system fault information via the system bus 2. When the signal line of the monitored device that can be accommodated by the supervisory signal relay device 3 is full, the supervisory signal relay device is added and expanded.
Since the monitoring signal relay device is connected to the monitoring device by bus,
There is no restriction on the number of connections.

Note that, in order to improve reliability, the gist of the present invention is not impaired even if the signal line that conveys the failure of the monitored device is pulled into a plurality of monitoring signal relay devices. Further, even if the failure of the devices of the same type of the monitored device is ORed and pulled into the monitoring signal relay device, the gist of the present invention is not impaired.

Further, even if the supervisory signal relay function is combined with a device having a unique function, the gist of the present invention is not impaired. In this case, it is sufficient to provide the failure acceptance circuit 8 in this device, which is advantageous in that it can be realized economically.

〔The invention's effect〕

As described above, according to the present invention, since the supervisory signal relay device detects a failure of the monitored device and notifies the monitoring device asynchronously and asynchronously via the system bus, the failure information of the monitored device is It is possible to collect in the monitoring device without giving any restriction to the change of the system configuration. Therefore, the monitoring device can be configured without being affected by hardware with respect to the change of the system configuration.
