Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention intervenes between a monitoring device and each monitoring target device and transmits from each monitoring target device when the monitoring device processes the monitoring information collected from a plurality of monitoring target devices. The present invention relates to a monitoring information relay device that receives the monitored information, performs preprocessing, and transmits the processing result to the monitoring device.

2. Description of the Related Art Generally, in a device having a large number of device constituent parts, the inside of the device housing is divided into several device constituent shelves and the functionally related device constituent parts are the same for ease of maintenance. The packaging is made hierarchical by accommodating it in the device configuration shelf. FIG. 8 shows an example of an in-apparatus monitoring method in an apparatus having such a configuration. Here, a common shelf for accommodating parts (such as a monitoring unit) related to the operation of the entire device is provided above the plurality of device configuration shelves.

As shown in the figure, the monitoring section 2 of the common shelf and each apparatus configuration section 3 of the apparatus configuration shelf are connected by a serial communication line. When the monitoring unit 2 requests monitoring information from each device configuration unit 3 through the serial communication line, each device configuration unit 3 returns the monitoring information collected by self-monitoring to the monitoring unit 2 through the serial communication line in response to the request. To do.

In this case, the monitoring unit 2 collects the monitoring information from each device configuration unit 3 sequentially through one serial communication line by performing communication control such as polling and transmitting / receiving serial communication data. FIG. 9 shows, as an example, a format example of serial communication data transmitted and received between the monitoring unit and the clock distribution unit in the transmission device or the like. The request data transmitted by the monitoring unit to the clock distribution unit includes a bit indicating the beginning of the data and address information for identifying the clock distribution unit. The response data returned by the clock distribution unit to the monitoring unit is the same as the first bit of the data and address information, but the clock input disconnection, clock output disconnection, device alarm, etc. follow as monitoring information, and finally to confirm the normality of communication. CRC (cyclic redundancy check) calculation result is added.

The monitoring unit 2 collects monitoring information generated according to the state of each device configuration unit 3 in addition to the monitoring information returned by each device configuration unit 3 through the serial communication line. For example, the package of the device component 3 may not be mounted on the connector, or the power may be cut off even if it is mounted. Therefore, each device component may be turned on according to the mounting state or the power-off state.・ Generates an off DC signal to monitor 2
Collects these DC signals so that the state of each device component 3 can be determined.

In the device configuration example of FIG. 8, monitoring information (hereinafter referred to as a mounting state, a power-off state, etc.) of each device configuration unit (hereinafter,
DC information is collected by directly connecting DC signal lines corresponding to (DC information) to the monitoring unit 2. However, in this method, since DC signal lines corresponding to the number of DC information are connected in parallel to the monitoring unit 2, a large number of input terminals of the monitoring unit 2 are required in a device having a large number of device components, and the device component 3 It is difficult to support expansion. Therefore, in the device configuration example shown in FIG. 10, the relay unit 1 is provided for each device configuration shelf,
The DC information about each device configuration unit 3 is input in parallel to the relay unit 1 in the same device configuration shelf, the DC information is parallel / serial converted in the relay unit 1, and then the monitoring unit 2 as serial communication data through the serial communication line. I am trying to send it to you. According to this method, the DC information can be transmitted to the monitoring unit 2 in the same format as the serial communication data through one serial communication line.

The monitoring unit 2 may perform some pre-processing on the monitoring information before monitoring the operation of the entire device based on the collected monitoring information. For example, in the case of the above-mentioned monitoring information about the clock distribution unit, if the clock distribution unit is not mounted, the mounting state indicates abnormal (not mounted), but at that time, the power-off state is also abnormal (disconnected), Since the clock distribution unit cannot perform self-monitoring, monitoring information other than mounting information is meaningless. Further, although the clock distribution unit is mounted and the power supply cut-off state is normal, when the clock input cut-off is abnormal, the clock output cut-off and the device alarm also become abnormal. In this example, there is a priority among each monitoring information, that is, mounting information> power supply disconnection information> clock input disconnection> device alarm> clock output disconnection, and if higher level monitoring information becomes abnormal, lower level monitoring information also becomes abnormal. Or it makes no sense. Therefore, when the higher order monitoring information becomes abnormal according to the priority order unique to each device configuration unit, the process of masking the lower order monitoring information (hereinafter referred to as priority processing) is performed in advance so that the subsequent monitoring can be performed. Processing can be facilitated.

[0008]

In the conventional monitoring information collecting method, the monitoring unit separately collects the monitoring information obtained by self-monitoring in each device configuration unit and the DC information generated in each monitoring configuration unit. , Stored in two or more storage locations. Then, the monitoring unit performs the above-mentioned priority processing on all the device configuration units while reading the monitoring information from the plurality of monitoring information storage locations for each device configuration unit, and further performs the priority processing across the device configuration units and the device configuration shelves. Also do. Therefore, in a device that collects a wide variety of monitoring information from a large number of device components, if the monitoring information is collected and prioritized by the conventional method, the number of steps becomes redundant and the processing speed is reduced.

The present invention has been made in view of the above problems, and unifies monitoring information collected from a plurality of monitored devices, further pre-processes the monitoring information to some extent, and then relays the monitoring information to the monitoring device. It is an object of the present invention to reduce the processing load on the monitoring device by providing the monitoring information relay device.

Therefore, the monitoring information relay device 5
0 can collect status monitoring information of each monitoring target device 55.

The monitoring device 54 is connected to one or more monitoring information relay devices 50 through a common serial communication line. When the monitoring device 54 requests the monitoring information relay device 50 for the monitoring information, each monitoring information relay device 50 responds to the request by collecting the monitoring information collected from each connected monitoring target device 55 for each monitoring target device.
