detailed description

It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Embodiments of the present invention provide an Internet of Things alarm suppression method.

Referring to FIG. 1, FIG. 1 is a schematic flowchart diagram of a first embodiment of an Internet of Things alarm suppression method according to the present invention.

In the first embodiment, the method for suppressing the Internet of things alarm includes:

Step S10: When receiving the alarm information reported by the device in the Internet of Things, determining whether the device for reporting the alarm information is a device in a preset critical path;

Before the device in the Internet of Things starts to report the alarm information, configure related configuration parameters on the server of the network management system (that is, the Internet of Things alarm suppression system). The related configuration parameters include: critical path configuration, various suppression protocol configurations, and processing groups. The personnel, the priority of each group, the priority weight of the group, the alarm analysis strategy, etc.; in the process of configuring the critical path, the critical path is generally composed of an IP address or an IP segment as a key to form a tree structure. Each node needs to be configured with a suppression protocol. The suppression protocol includes the Internet Control Message Protocol (ICMP) and the Simple Network Management Protocol (SNMP).

After receiving the alarm information reported by the device, the network management system first determines whether the device is a device in the critical path. If yes, proceed to the next step; if not, discard the alarm information directly, thus directly shielding the non-critical path. The alarm information reported by the device is used to suppress the alarm information reported by the device on the critical path. This greatly reduces the pressure on the alarm server and reduces the risk of alarm storms.

In step S20, if the device that reports the alarm information is the device in the preset critical path, it is determined whether the historical alarm information with the same protocol as the alarm information has been reported in the reporting device.

In this step, the device in the critical path is repeatedly reported to report the same alarm information, which further reduces the number of useless alarms in the network and further optimizes the network to avoid alarm storms.

Step S30: If the historical alarm information with the same protocol as the alarm information is not reported in the reporting device, the device broadcasts the alarm information to the device in the broadcast group.

If the reporting device of the alarm information is not the device in the preset critical path, or if the historical alarm information that is the same as the protocol corresponding to the alarm information has been reported in the reporting device, step S40 is performed, that is, the alarm information is discarded.

In this embodiment, when the alarm information reported by the device in the Internet of Things is received, it is determined whether the device for reporting the alarm information is a device in a preset critical path, and if yes, the protocol corresponding to the alarm information is further determined. Whether the same historical alarm information has been reported in the reporting device, and if not reported, the alarm information is broadcast to the devices in the broadcast group; thus, the reported alarm information is no longer isolated from each other, but is rich. When the critical node of one of the critical paths fails, the alarms reported by other related nodes on the critical path can be suppressed in time, which greatly reduces the pressure on the alarm server, reduces the risk of generating an alarm storm, and collects efficiently. Handle the purpose of the alarm in time.

2 is a schematic flowchart of a second embodiment of an Internet of Things alarm processing method according to the present invention;

In the second embodiment, the method for suppressing the Internet of things alarm includes:

Step S50: If the historical alarm information with the same protocol as the alarm information is not reported in the reporting device, determine whether the keyword in the alarm information meets the preset condition;

The key field in the alarm information includes the alarm code, the type of the alarm, the type of the alarm device, and the additional information. The alarm information is analyzed to determine whether the key segment in the alarm information meets the preset condition. For example, the preset condition specifies that the alarm code is If the singular alarm information needs to be broadcast, if the alarm code of the reported alarm information is singular, it is determined that the alarm information needs to be broadcast to the devices in the broadcast group.

Step S30: If the key segment in the alarm information meets the preset condition, the device broadcasts the alarm information to the device in the broadcast group.

If the reporting device of the alarm information is not the device in the preset critical path, or if the historical alarm information with the same protocol as the alarm information has been reported in the reporting device, or the key segment in the alarm information does not meet the preset condition, Then, step S40 is performed, that is, the alarm information is discarded.

Further, referring to FIG. 3, FIG. 3 is a schematic flowchart of a step of broadcasting the alarm information to the devices in the broadcast group in FIG.

In this embodiment, step S30 includes:

Step S301, analyzing the key field, obtaining the range of the broadcast group of the alarm information and the priority of the broadcast group;

The scope of the broadcast group and the priority of the broadcast group can be configured. For example, the scope of the broadcast group can be divided into the maintenance group, the management group, and the implementation group. The priority of the different groups is configured. For example, the priority of the maintenance group is greater than that of the management group. The group priority is greater than the implementation group. In addition, the broadcast alarm level can also be configured, for example, the broadcast range of the first level alarm is the largest.

Step S302: Broadcast the alarm information to devices in the broadcast group according to the range of the broadcast group and the priority of the broadcast group.

After receiving the alarm information of the device, the network management system first analyzes the alarm information to obtain the broadcast range and priority of the information, and then starts broadcasting from the highest user group with the highest relevance. The user group also has the priority according to the configuration. The highest person starts broadcasting and pushes the alarm message by email and SMS. After the user confirms the alarm through the network management alarm system, the broadcast process is terminated. If the alarm is not confirmed and processed by the preset time (for example, 15 minutes), according to the group. The priority configuration inside, in turn, broadcasts an alarm message to other people in the group.

Further, referring to FIG. 4, FIG. 4 is a schematic flowchart diagram of a third embodiment of an Internet of Things alarm processing method according to the present invention.

In the third embodiment, the method for processing an Internet of Things alarm includes:

If the key segment in the alarm information meets the preset condition, step S301 is performed to analyze the key segment, and the range of the broadcast group of the alarm information and the priority of the broadcast group are obtained;

After the broadcast with the highest association is over, if the alarm information has not been processed, the system automatically upgrades the broadcast range and broadcasts to the next higher level group. This group should be the group with management and evaluation relationship with the previous group. The broadcast mode in the group is also performed according to the configured priority, and is broadcasted at intervals of a preset time (for example, 15 minutes) until the alarm information is processed. If the alarm information has not been processed after the broadcast of the group is complete, the alarm information is processed in the upward direction until the alarm information is processed. If the broadcast group is broadcasted, the alarm information is not processed and the broadcast process is automatically terminated.
