Description

Embodiments of the present invention relate to a network system, a monitoring system, a work management system, and a work management method.

Many network systems are provided with a monitoring system. For example, repeater systems introduced to prevent dead areas in cellular phone systems are also equipped with monitoring systems. The monitoring system constantly monitors the occurrence of alarms and the like in the repeater system. When an abnormality is detected in the monitoring system, work such as device replacement is required. Work management systems for managing this type of work are known.

Japanese Patent Application Publication No. 2010-273123

With existing technology, the monitoring system and the work management system are operated separately, and mutual cooperation cannot be said to be sufficient. For example, if an abnormality detected in the monitoring system requires action such as replacing the device, it is necessary to make a request to a maintenance company each time by e-mail or telephone, or to manually register it in the work management system. For this reason, the benefits of the long-awaited work management system cannot be utilized. Further, even though alarms generated during maintenance work should not be monitored and can be ignored, they are detected by the monitoring system, resulting in the need to check the work status each time. For this reason, the work was not efficient and there was room for improvement.

Therefore, an object of the present invention is to provide a network system, a monitoring system, a work management system, and a work management method that improve work efficiency.

According to the embodiment, the network system includes a monitoring system that monitors devices under its control, and a work management system that can communicate with the monitoring system. The monitoring system includes an alarm receiving section and a transmitting section. The alarm receiving unit receives an alarm issued from the device. When the alarm is received, the transmitting unit transmits a work request message corresponding to the alarm to the work management system. The work management system includes a receiving section and a registration processing section. The receiving unit receives the work request message. The registration processing unit prompts the user to register work information based on the received work request message.

FIG. 1 is a system diagram showing an example of a network system according to an embodiment. This system includes a monitoring system 100A and a work management system 100Z. The monitoring system 100A and the work management system 100Z are connected via a wired or wireless network 1000 and can communicate with each other.

The monitoring system 100A is connected to a plurality of devices A1 to An via a monitoring network ANet, and monitors and controls these devices A1 to An under its control. SNMP (Simple Network Management Protocol) is a typical protocol related to monitoring/control.

Further, client terminals T1 to Tm having a display and functioning as a display device can access the monitoring system 100A via the monitoring network ANet. The client terminals T1 to Tm can remotely check the alarm status and the like of the devices A1 to An.

The devices A1 to An are various devices such as, for example, an optical transmission device (base device), an optical transmission device (slave device), or a power supply device in an optical relay system, and are understood as stations. The embodiment assumes a station in a repeater system.

The work management system 100Z is provided to manage work such as device replacement, unit replacement, device inspection, and restart. Further, client terminals Z1 to Zp each having a display and functioning as a display device can access the work management system 100Z via the work management network ZNet.

In the following description, devices A1 to An will be referred to as device A unless it is necessary to distinguish them. Furthermore, if there is no need to distinguish between the client terminals T1 to Tm, they will be expressed as client terminals T, and if there is no need to distinguish between client terminals Z1 to Zp, they will be expressed as client terminal Z.

FIG. 2 is a functional block diagram illustrating an example of the monitoring system and work management system according to the embodiment. In FIG. 2, apparatus A includes various devices 1, an alarm detection section 2 that detects an alarm generated in the device 1, and an alarm transmission section 3 that notifies the monitoring system 100A of the detected alarm.

An alarm (for example, an SNMP-Trap message) issued from the alarm transmitter 3 of the device A1 is received by the alarm receiver 11 of the monitoring system 100A. The alarm includes information such as [station ID], [transmission time], and [alarm ID]. Various types of information included in the received alarm are additionally registered and accumulated in the alarm information database (DB) 12.

FIG. 3 shows an example of information registered in the alarm information DB 12. The alarm information is stored in the alarm information DB 12, for example, [management number], [station ID], [event occurrence date and time], [event clear date and time], [alarm ID], [alarm status], [alarm name], and [comment]. , and [display type]. Note that [display type] is an item for specifying grayout, non-display, etc. on the client terminal TA.

The monitoring system 100A (FIG. 2) further includes a screen interface (IF) 17 connectable to a client terminal T as a display device, a station information database (DB) 16, a station information registration section 15, a work management system cooperation section 13, It includes a mask processing section 14 and a mask information database (DB) 18. Among these, the screen IF 17 has a function as a display control section, and displays the acquired alarm information on the screen of the client terminal T, for example, in a list.

In the station information DB 16, station information of a subordinate station (apparatus A) is registered in advance by the station information registration unit 15 in accordance with a request from the client terminal T, for example. The station information includes information such as ID (IDentification) for identifying the devices A1 to An, IP (Internet Protocol) addresses, board information, and setting status.

FIG. 4 shows an example of information registered in the station information DB 16. The station information can be managed in a data structure including, for example, [management number], [group], [station name], [station ID], [device classification], and [device IP address].

When the warning from device A is received by the warning receiving unit 11, the work management system cooperation unit 13 (FIG. 2) serving as a transmitting unit transmits a work request message corresponding to the warning to the work management system 100Z. This work request message is received by the monitoring system cooperation unit 21 (functioning as a message receiving unit) of the work management system 100Z.

When the work request message is received, the screen interface (IF) 23 serving as a registration processing unit displays a prompt window on the client terminal Z serving as a display device to urge the user to register work information based on the work request message. Work information etc. registered by the user are recorded in a work management database (DB) 22.

FIG. 5 is a diagram showing an example of information registered in the work management DB 22. Work information is stored in the work management DB 22, for example, [management number], [group], [station name], [station ID], [work time (start)], [work time (end)], [work content], and can be managed in a data structure including [person in charge]. For example, it can be seen that [work time (start)] is the start time of the work indicated by [work content], and that the work is scheduled to end at the time of [work time (end)].

The work information registered using the client terminal Z (FIG. 2) is notified to the mask processing unit 14 of the monitoring system 100A via the monitoring system cooperation unit 21. The mask processing unit 14 selectively sets mask attributes for each piece of alarm information based on the work information registered at the client terminal Z. The set information (mask information) is registered in the mask information DB 18.

FIG. 6 is a diagram showing an example of information registered in the mask information DB 18. The mask information is stored in the mask information DB 18 as a data structure including, for example, [management number], [mask type], [mask period (start)], [mask period (end)], [user ID], and [comment]. can be managed by It is possible to set attributes containing such information for each individual alarm.

For example, if board replacement is specified as [Construction Content], an alert related to [board removal] will be issued from the target device. This is of course something that can be predicted, so there is little need to deal with it again. Therefore, by specifying the period of the construction work (from the start to the end of the work time) and setting a mask, it becomes possible to improve convenience for the user (system administrator, etc.).

The screen IF17 (FIG. 2) serving as a display control section masks the alarm displayed on the client terminal T according to the mask information recorded in the mask information DB 18 of FIG. In other words, by changing the display color or displaying an alarm with a mask attribute by shading, the alarm can be distinguished from an alarm without a mask attribute. Alternatively, there may be a mode in which an alarm for which a mask attribute is set is not displayed.

Next, the operation of the above configuration will be explained. In the following, the apparatus A1, the client terminal T1, and the client terminal Z1 will be represented as the main bodies of processing, but the same applies to other apparatuses and client terminals.

FIG. 7 is a sequence diagram illustrating an example of message exchange according to the embodiment. In FIG. 7, when an alarm event occurs in the device A1 (step S1), it is detected by its own alarm detection unit 2, and an alarm corresponding to the event is issued (step S2). There is not only one alarm, but multiple alarms may occur almost simultaneously.

The issued alarm is received by the monitoring system 100A (step S3), and the alarm information is recorded and accumulated in the alarm information DB 12. Further, the alarm information referenced from the alarm information DB 12 is listed and displayed (in a form format) on the display of the client terminal T1, as shown in FIG. 8, for example (step S4).

Referring to the [Occurrence time] column in the GUI (Graphical User Interface) window of FIG. 8, two alarms occurred at 15:00 on January 2, 2019. Referring to the [System Name (Vendor)] column, it can be seen that this alarm is for device A of vendor (Company X).

The window in FIG. 8 is provided with a [Work Request] button for the user to request work from a vendor or the like. The user who wants to request work selects the alarm for which he wants to request work, and clicks the "Request Work" button (Yes in step S5). Then, a window like the one shown in Figure 9 will open.

The window in Figure 9 includes detailed information on the alarm selected in the window in Figure 8, as well as a column for writing the work you would like to request (such as MU replacement), or a drop-down list for specifying a maintenance company. . When the specified items are filled in and the "Register" button is clicked, a work request message is sent from the monitoring system 100A to the work management system 100Z (step S6). The work request message includes information such as the target station, alarm information, and work details.

When the work management system 100Z receives the work request message (step S7), work information is recorded and accumulated in the work management DB 22. Then, for example, a window as shown in FIG. 10 is displayed on the display of the maintenance contractor's client terminal Z1.

A list of requested tasks is displayed in the window of FIG. 10 (step S8). Every time a work request message is received, information about the requested work is added to, for example, the bottom line. When the line indicated as [New] in [Status] is selected and the [New Registration] button is clicked, the window shown in Fig. 11 is displayed. The windows shown in FIGS. 10 and 11 prompt the user to register work information based on the work request message.

FIG. 11 is a diagram showing an example of a prompt screen prompting the user to register work information. Detailed information on the target alarm is displayed in this window, and the contractor performing the work can check the status of the work request from the display of the client terminal Z1. The trader clicks the [Edit] button and inputs detailed information regarding the work as shown in FIG. 12 (Step S9). An important piece of detailed information is, for example, the working time, and referring to FIG. 12, it can be seen that 2019/1/4 7:00 to 2019/1/4 10:00 is specified. When the [Register] button in FIG. 12 is clicked, the work details are accepted (step S10), and the input information is registered in the work management DB 22. Further, work information is transmitted to the monitoring system 100A via the monitoring system cooperation unit 21. In the monitoring system 100A that has acquired this, the mask processing unit 14 registers mask information based on the station information of the work target, work time, etc. in the mask information DB 18 (step S11). When the registration is completed, the content displayed on the display of the client terminal Z1 changes from the content shown in FIG. 10 to the content shown in FIG. 13, and the [Status] of the target alarm becomes [Registered].

FIG. 14 is a sequence diagram illustrating an example of a processing procedure when a masked alarm occurs. In FIG. 14, when an alarm event occurs in the device A1 (step S21), an alarm corresponding to the event is issued (step S22). The issued alarms are received by the monitoring system 100A (step S23), and are listed and displayed (in form) on the display of the client terminal T1 (step S24). However, at this time, since the target alarm is masked, it is masked on the display of the client terminal T1, as shown in FIG. The diagonal hatching in FIG. 15 indicates that the alarm is displayed as a mask, for example, by color coding, shading, shading, or the like.

As described above, in this embodiment, the monitoring system 100A and the work management system 100Z are linked, and a work request message is sent to the work management system 100Z based on the alarm received by the monitoring system 100A. By doing so, it becomes possible to streamline a series of procedures from the generation of an alarm to maintenance work. Further, according to the embodiment, the alarm information displayed on the client terminal A is automatically masked according to the registered work information. Thereby, it is possible to prevent the supervisor from recognizing unnecessary alarms, and in turn, it is possible to reduce the burden of monitoring work. For these reasons, it is possible to provide a network system, a monitoring system, a work management system, and a work management method that can improve work efficiency.

Note that this invention is not limited to the above embodiments. For example, in the window shown in FIG. 9, a plurality of alarms may be selected, and a work request message may be sent all at once with a single click. A possible example of this is a user interface in which one alarm is selected by specifying a tab in a window with a plurality of tabs. In other words, the work request message may include information related to a plurality of alarms.

Further, the network system according to the embodiment is applicable not only to monitoring/controlling a repeater system but also to any system in which system monitoring and work management are divided.

Although an embodiment of the invention has been described, this embodiment is presented by way of example and is not intended to limit the scope of the invention. This novel embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. This embodiment and its modifications are included within the scope and gist of the invention, as well as within the scope of the invention described in the claims and its equivalents.
