Abstract

PURPOSE:To prevent the reduction in the monitor efficiency by arranging a sub monitor device supplying information relating to electric connection disconnection and monitor information representing a change to a monitor for at least each frame. CONSTITUTION:A sub monitor 31 applies polling each monitored controller in a frame 30 in place of a monitor 10A and connects any monitored controller in the frame 30 to a portable controller 11 electrically to apply setting revision of the operating condition and collects electric connection/disconnection information disconnecting the electric connection again, that is, information relating to the generation of the setting change in the entire operation and alarm information causing an abnormal change in the monitor information in the polling. Then the monitor 10A applies polling the sub monitor 31 periodically and applies polling for grasping detailed monitor information to the monitored controller grasping a change in the operation condition setting change or monitor information by the portable controller 11 implemented by the sub monitor device 31. Thus, the monitor efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a polling method for a monitoring device, and in particular, the present invention relates to a polling method for a monitoring device, and particularly to a polling method for a monitoring device, and in particular, the present invention relates to a polling method for a monitoring device.
The present invention relates to a polling method for a monitoring device that monitors each monitored control device for each rack having one monitored control device by polling.

[Conventional technology]

A monitored control device whose system operation is monitored.

For example, a monitoring device that has at least one (2) usually multiple monitored controlled devices such as multiplexing equipment installed on the same rack, and collects information for operation monitoring by polling the multiple monitored controlled devices. is well known. In this case, system operating conditions are set in advance for each of the monitored controlled devices whose operation is monitored, and some of these setting conditions are changed by a portable control device independent of the monitoring device, while others are not. be.

FIG. 3 is a configuration diagram showing a first example of a polling method of a conventional monitoring device. A plurality of monitored control devices 32A-
1 to 32 A-n are installed on the same rack 30A, and the portable control device 11A controls settings related to changes in system operation via the signal line 21A and the interface port 3.
00A-1 to 300A/n, the monitoring device 10
C regularly collects monitoring information by polling the monitored and controlled devices 32A-1 to 32A-n that are multiple-connected via the signal line 2° (C).

FIG. 4 is a configuration diagram showing a second example of a polling method of a conventional monitoring device.

The second example shown in FIG. 4 includes a plurality of racks 30A-1 to 30A-

Monitoring information was collected through regular polling via (D).

[Problem to be solved by the invention]

In the case of the first example shown in FIG. 3, the polling method of the conventional monitoring device described above does not know when the settings will be changed by the portable control device F11A, so polling is performed periodically, so there are no settings changes. Despite this, it is necessary to repeatedly poll the monitoring information even though there is no significant change, and the polling cycle for each monitored control device in the entire system becomes longer, and the real-time monitoring system It has the disadvantage of causing a decline in sexuality.

Furthermore, in the case of the second example shown in Fig. 4, it is unavoidable to repeatedly poll monitored devices for which there is no monitoring information or whose monitoring information does not change, and the number of monitored devices increases. This method has the drawback that the overall monitoring information collection time increases correspondingly, and the monitoring efficiency of the monitoring system decreases.

[Means to solve the problem]

The method of the present invention provides for each built-in rack of at least one rack having at least one monitored control device operating under the control of a portable control device capable of independently changing and controlling preset system operating conditions. In a polling method of a monitoring device that collects monitoring information regarding a monitored controlled device by polling, each monitored controlled device in the rack is polled on behalf of the monitoring device, and each of the portable control device and the at least one rack is polled. A sub-monitoring device that performs electrical contact regarding changes in operating condition settings with the monitored controlled device and supplies information regarding the electrical contact and the monitoring information when there is a change to the monitoring device. It is arranged and configured for each of the at least one rack.

Further, the method of the present invention is a polling method for a monitoring device that collects monitoring information about at least one rack having at least one monitored device whose system operation is monitored in advance by polling. at least one monitored device built into each of the at least one rack that outputs information indicating the occurrence of a change; and a sub-device disposed in each rack to receive information indicating the occurrence of a change in the self-monitored information. A monitored device polls a monitoring device and the sub-monitoring device arranged for each rack, and receives information indicating the occurrence of a change in its own monitored information output by at least one monitored device for each rack. A monitoring device that obtains detailed alarm information only for alarms.
