Description

  The present invention relates to a control system using OpS clients, and more particularly to a control system for a transmission apparatus using a plurality of OpSs in a transmission apparatus constituting a communication network system and an OpS for monitoring / controlling network components including the transmission apparatus. Here, OpS is an abbreviation for an operation system.

  FIG. 10 is a diagram illustrating a configuration example of the OpS and the transmission apparatus. As shown in the figure, the operation system includes a client, a server, and a transmission device. In the figure, 1 is a plurality of OpS clients, and 2 is a server that is connected to these OpS clients 1 and performs various controls. The OpS (operation system) includes an OpS client 1 that performs screen display and operation, and a server 2 that performs information management by a database (DB) 3 and control of a transmission apparatus.

  Reference numeral 5 denotes a communication network connected to the server 2. Reference numeral 4 denotes a transmission apparatus constituting the communication network 5. The database 3 stores information A, B, and C as shown in the figure. The content of information A is “aaaaaa”, the content of information B is “bbbbbb”, and the content of information C is “ccccc”.

  Normally, a plurality of OpS clients 1 are connected to the server 2. The figure shows the case of three units from OpS1 to OpS3. Then, each OpS client 1 can issue a control request to the server 2 individually. The server 2 processes the control requests of the OpS client 1 in the requested order, and implements control to the transmission device 4 and reflection to the database 3. The outline of the operation of the system configured as described above will be described as follows.

  When a read / control operation is performed on the server 2 from OpS1 (C1), the server 2 performs read / control on the communication network 5 (C2). Upon receiving a response from the communication network 5 (C3), the server 2 stores information in the database 3. For example, in this way, for example, data “aaaaaa” is stored in the database 3.

  Next, the server 2 reads information from the database 3 (C5), notifies the read information to OpS1 (C6), and OpS1 displays the received response on the screen (C7).

As a conventional system of this type, for example, when operations from a plurality of monitoring control terminals compete, a system is known in which contacts are communicated and adjusted between terminals (for example, see Patent Document 1). Also, in the power distribution system monitoring and control apparatus, when the influence range due to the operation overlaps (competes), a system that compares and determines the priorities of the two operators in which the overlap has occurred and preferentially operates the operators with higher priorities Is known (see, for example, Patent Document 2). There is also known a system that automatically updates management information of a required number of computers only by updating management information on one computer (see, for example, Patent Document 3).
JP 2003-6264 A (page 3, page 4, FIG. 1) JP 2001-112173 A (page 4, FIG. 1) JP 2001-75900 A (page 7, FIG. 1)

  As a first problem, in the conventional technique, when a control request is issued almost simultaneously from a plurality of OpS clients, there is a problem in that the control that is processed later is always reflected. FIG. 11 is an explanatory diagram of a problem to be solved by the invention. As shown in FIG. 11, a plurality of OpS clients (OpS1, OpS2, OpS3) are connected to one server 2, and the server 2 holds information A to information C in the database 3. To do. 11, the same components as those in FIG. 10 are denoted by the same reference numerals. In the figure, reference numeral 1 denotes an OpS client, which is provided from OpS1 to OpS3. 2 is a server, and 3 is a database (DB) connected to the server 2. A transmission device 4 is connected to the network 5. The operation of the system configured as described above will be described as follows.

  FIG. 12 is a diagram showing a processing flow of the system shown in FIG. The operation of the system will be described below with reference to this processing flow. First, OpS1 makes a control request to the server 2 to change the information A from “aaaaaa” to “xxxx” (C1). At almost the same time, OpS2 issues a control request to the server 2 to change the information A from “aaaaaa” to “yyyyyy” (C2). OpS1 and OpS2 do not know that they are trying to update information A to each other because they are in remote locations.

  In the server 2, in order to sequentially process the control requests from the OpS client 1, first, control for changing the information A of the transmission device to “xxxx” is executed (C3), and then the information of the database 3 is updated to “xxxx”. (C4). When the processing is completed, the control result is reported to OpS1 (C5). Immediately after the control of OpS1, control is performed to change the information A to the transmission apparatus by OpS2 from “xxxxxxxx” to “yyyyy” until then (C6), and subsequently the information A in the database 3 is changed to “yyyyyy”. To "" (C7). When this process ends, the control result is returned to OpS2 (C8).

  As is clear from the above description, immediately after the information A is updated to “xxxx” by OpS1, it is updated to “yyyy” by OpS2, and the information of OpS1 is lost.

  In addition, as a conventional exclusive control method, there is a method of not accepting the control of other clients while one client is controlling, but in normal operation, a large number of clients are connected and operated. This exclusive control method may cause inconvenience.

  As a second problem, there is a case where it is desired to perform a series of operations that take time from one client in operation. However, in the conventional technology, there is a case where it is difficult to efficiently execute a series of control because the processing is competed by the interruption of the control from another client during the control.

  As a third problem, since all control requests can be made regardless of the skill (skill) of the operator who operates the client, an operational problem may occur due to an erroneous operation by an operator with low skill.

  The present invention has been made in view of such problems, and enables efficient operation by a plurality of clients, and prevents an operational problem from being caused by an erroneous operation by an operator with low skills. An object of the present invention is to provide an OpS client control system.

(1) The invention described in claim 1 is as follows. FIG. 1 is a principle block diagram of the present invention. The same components as those in FIG. 10 are denoted by the same reference numerals. The system shown in the figure includes a plurality of OpS clients 1 and a server 2 connected to each other, a server 2 and a transmission device 4 constituting a communication network 5 connected to each other, a plurality of transmission devices 4 constituting a communication network system, and A system for controlling / monitoring network components including the transmission apparatus 4 is configured.

The server 2 includes a database 3 for storing information, and when a control request is generated from the OpS client 1, connection control of the OpS client 1 is performed while referring to the database 3 corresponding to the type of the control request. And a control means 7 for performing the above.
(2) According to the second aspect of the present invention, when the control is simultaneously executed from a plurality of OpS clients 1, the control means 7 of the server 2 compares the information of the client / server before the control, and according to the comparison result And determining whether or not the control is performed.

  According to the present invention, when an OpS client makes a control request to a server, information that is currently held by the OpS client (hereinafter referred to as retained information) is updated simultaneously with information that is updated (hereinafter referred to as updated information). Send at the same time. In the server, the control means compares the holding information transmitted from the OpS client with the holding information held in the database by the current server, and if they match, control from another OpS client is performed. It is determined that there is no transmission, and the transmission apparatus and the database are controlled.

If the stored information sent from the client and the information stored in the database by the server do not match, the control means will send another request while the server processes it after the client issues a control request. It is determined that the information has been updated by the control from the client, the process is interrupted, and the information is updated by another client to the control request source OpS client, so the database is read and changed to the latest information. Encourage you to.
(3) In the invention described in claim 3, the control means 7 can control / monitor only one specific OpS client 1 among the plurality of OpS clients 1, and can only monitor other OpS clients 1. It is characterized by controlling to become.

  According to the present invention, only one specific OpS client can occupy a control operation. Specifically, the control operation occupation control request is issued from the OpS client that occupies the control operation to the server. At this time, the OpS client transmits its own client information (unique one such as an IP address) and occupied time (start time and end time). The control means of the server stores information transmitted from the OpS client in a database, and checks this information when there is a control request from the OpS client.

  If the OpS client of the control request source is an OpS client that has issued an occupancy request, monitoring / control is possible, and if it is any other OpS client, control of information is impossible and only reference is possible.

In addition, the OpS client that occupies the control operation can be switched. When switching is performed, the server updates the dedicated client information held in the database. As a result, the switching source OpS client becomes a client that can only be monitored, and the switching destination OpS client becomes a client that can be monitored / controlled.
(4) The invention according to claim 4 provides a user level to each OpS client 1 and assigns a user level to the data when performing the control, and the control means 7 includes the user level of the OpS client and the user level. The server 2 is compared with the user level of the information to determine whether or not the control is performed.

  According to the present invention, a user level is provided for each OpS client. The OpS client transmits its own client information (unique information such as an IP address) and a user level simultaneously with the update information when executing a control request to the server. The server control means compares the user level transmitted from the OpS client with the user level of the information held in the database, and only when the transmitted user level is higher, controls the transmission apparatus and the database. Update.

  Further, when updating the database, the updated OpS client information and the user level are stored. If the user level sent by the OpS client is lower than the user level of the information held in the database, the control means checks the OpS client that last updated the information on the server and Request for approval to update the information. Only when it is approved there, the transmission device is controlled and the database is updated. If not approved, the control request source OpS client is notified that the control request has been rejected.

(1) According to the first aspect of the present invention, when a control request is generated from an OpS client, the control means responds to a control request from a plurality of OpS clients according to the type of the control request. Connection control can be performed.
(2) According to the invention described in claim 2, even when the control is overlapped by a plurality of OpS clients, the control of other clients is not unintentionally erased. Further, the exclusive control according to the present invention does not limit the processing of other clients during the processing of a certain client as in the prior art, so that efficient operation is possible with a plurality of OpS clients.
(3) According to the invention described in claim 3, since a series of operations that take time is not interrupted by control from another OpS client, efficient operation is possible.
(4) According to the invention described in claim 4, the user level of the client can be determined according to the skill of the operator, and it is possible to prevent an operational problem from being caused by an erroneous operation by a low-skilled operator. It becomes possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 2 is a block diagram showing a first embodiment of the system of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. This will be described with reference to the processing flow shown in FIG. In the figure, 1 is a plurality of OpS clients, 2 is a server to which these OpS clients 1 are connected, 3 is a database connected to the server 2, 5 is a communication network connected to the server 2, and 4 is the communication network 5. Is a transmission device connected to Reference numeral 7 denotes control means provided in the server 2. For example, a computer is used as the control means 7. The operation of the system configured as described above will be described as follows.

  First, OpS1 makes a control request to the server 2 to update the transmission device information A from “aaaaaa” to “xxxx” (C1). At almost the same time, OpS2 makes a control request to server 2 to change information A of the transmission apparatus from “aaaaaa” to “yyyyyy” (C2). At this time, the OpS client 1 transmits to the server 2 information (retention information) currently held by the OpS client 1 together with information to be updated (update information). In other words, OpS1 transmits update information “xxxx” and retention information “aaaaaa”, and OpS2 transmits update information “yyyy” and retention information “aaaaaa”.

  In the server 2, the control unit 7 sequentially processes control requests from the OpS client 1. First, the control means 7 compares the holding information transmitted from OpS1 with the information A in the database 3 of the server 2 (C3). Here, since both pieces of information “aaaaaa” coincide with each other, the control unit 7 executes the control of OpS1 on the transmission apparatus 4 (C4), and updates the information A in the database 3 (C5). Thereafter, the control means 7 notifies OpS1 that the control has been normally performed (C6).

  Next, the control means 7 accepts a control request from OpS2. As before, the holding information transmitted from OpS2 is compared with the information A of the server 2 (C7). Since the information A of the server 2 has been changed to “xxxx” under the control of the previous OpS1, both values do not match. Therefore, the control means 7 does not execute the control of OpS2, but notifies OpS2 that the information A has been updated by another OpS client 1 to OpS2 (C8). From the response result of the server 2, OpS 2 knows that the information A has been updated by another OpS client 1 by rereading the state.

According to this embodiment, when a control request is generated from the OpS client 1, the control means 7 responds to the control request from a plurality of OpS clients 1 according to the type of the control request. Control can be performed. Further, even when the control is overlapped by a plurality of OpS clients, the control of other clients is not unintentionally erased. In addition, the exclusive control according to the present invention does not limit the processing of other OpS clients 1 during the processing of the OpS client 1 as in the prior art, so that efficient operation with a plurality of OpS clients 1 is possible. It becomes possible.
(Second embodiment)
FIG. 4 is a block diagram showing a second embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals. This will be described with reference to the processing flow shown in FIG. In the figure, 1 is a plurality of OpS clients, 2 is a server to which these OpS clients 1 are connected, 3 is a database connected to the server 2, 5 is a communication network connected to the server 2, and 4 is the communication network 5. Is a transmission device connected to Reference numeral 7 denotes control means provided in the server 2. For example, a computer is used as the control means 7. The operation of the system configured as described above will be described as follows.

  First, OpS1 issues a control request for occupying control of the server 2 and the transmission device 4 to the server 2 for a certain period of time. At this time, OpS1 transmits its own client information (unique information such as an IP address) to the server 2 (C1). In the server 2, the control means 7 receives the control request for OpS 1 and checks the occupied client information on the database 3. If it is already occupied by another OpS client, an error response is sent to OpS1.

  If there is no currently occupied OpS client, the information of the OpS client that issued the control request and the occupied time information are stored in the database 3 (C2), and it is confirmed that the occupation process has been normally completed for OpS1. Notify (C3). Here, “OpS1” is stored in the occupied terminal portion of the database 3, “hh: mm” is stored as the start time, and “hh ′: mm ′” is stored as the end time.

  Next, a control request is made by OpS2 to change the information A of the transmission apparatus from “aaaaaa” to “yyyyyy” (C4). The control means 7 receives the OpS2 control request and checks the occupied client information in the database 3 (C5). Since the occupied terminal is OpS1 by the operation of the previous OpS1, the control means 7 does not accept the control request of OpS2, and the server 2 is occupied by OpS1 with respect to OpS2, so that the control cannot be performed. (C6).

  As described above, in this embodiment, the OpS client OpS1 that issued the occupation control request is a client that can be controlled and monitored, and the other OpS clients 1 (OpS2 and OpS3) can only be monitored. Become a client. Further, the occupation of the server 2 by OpS1 is released when the end time of the database 3 is checked by a request for releasing the occupation by OpS1 or by the periodic check process of the server 2, and it is detected that the end time has passed.

According to this embodiment, since a series of operations that take time is not interrupted by control from other OpS clients, the operation can be performed efficiently.
(Third embodiment)
Further, according to the present invention, as shown in FIG. 6, it is possible to switch the occupied client. FIG. 6 is a block diagram showing a third embodiment of the system of the present invention, and FIG. 7 is a diagram showing the flow of processing in the third embodiment. The same components as those in FIG. 4 are denoted by the same reference numerals. In the figure, 1 is a plurality of OpS clients, 2 is a server connected to the OpS client 1, 5 is a communication network connected to the server 2, and 4 is a transmission device connected to the communication network 5. 3 is a database connected to the server 2, and 7 is a control means provided in the server 2. For example, a computer is used as the control means 7. The operation of the system configured as described above will be described as follows.

Here, as shown in FIG. 6, the exclusive client can be switched. In the figure, a method of switching the occupied client from OpS1 to OpS2 is shown. First, OpS1 issues a control request for switching the occupied client to OpS2 to the server 2 (C1). The control means 7 of the server 2 receives the control request for OpS1, and updates the information of the occupied terminal in the database 3 from “OpS1” to “OpS2” (C2). When the processing is completed, the result is notified to OpS1 (C3). By the above procedure, OpS1 and OpS3 become OpS clients that can only be monitored, and OpS2 becomes an OpS client that can be controlled / monitored.
(Fourth embodiment)
FIG. 8 is a block diagram showing a fourth embodiment of the present invention, and FIG. 9 is a diagram showing a processing flow of the fourth embodiment. In the figure, 1 is a plurality of OpS clients, 2 is a server connected to the OpS client 1, 5 is a communication network connected to the server 2, and 4 is a transmission device connected to the communication network 5. . 3 is a database connected to the server 2, and 7 is a control means provided in the server 2. For example, a computer is used as the control means 7.

  As shown in the figure, it is assumed that three OpS clients 1 (OpS1, OpS2, OpS3) are connected to one server 2 and a transmission device control request is executed. Each OpS client 1 is provided with a user level indicating a priority. Each user level is set to OpS1 (5)> OpS2 (3)> OpS3 (1). It is assumed that the initial values of the user level of the information stored in the database 3 are all “3”. The operation of the system configured as described above will be described as follows.

  First, OpS1 issues a control request to the server 2 so as to change the information A of the transmission apparatus to “xxxx” (C1). The control means 7 of the server 2 receives the OpS1 control request, and checks the user level of the information A held in the database 3 and the information of the last updated terminal (C2). Here, since the user level “5” of OpS1 is higher than the user level “3” of the information A stored in the database 3, the control of OpS1 is performed on the transmission apparatus (C3). Thereafter, the information of the database 3 is updated from “aaaaaa” to “xxxx”, and the user level is updated from “3” to “5”. Further, “OpS1” is stored in the last updated terminal information (C4), and the control result is notified to OpS1 (C5).

  Next, OpS2 issues a control request to the server 2 so as to change the information A of the transmission apparatus 4 to “yyyyyy” (C6). The control means 7 of the server 2 receives the OpS2 control request and checks the user level of the information A held in the database 3 and the information of the last updated terminal (C7). Here, the user level of the information A held in the database 3 is updated to “5” by the control of the previous OpS1. This user level is higher than the user level of OpS2 (“3”).

  Therefore, the control means 7 issues an approval request for the update control of OpS2 to OpS1, which is the final update terminal (C8). When this approval request is approved by OpS1 (C9), the control means 7 performs control of OpS2 on the transmission apparatus 4 (C10), and updates the information A of the database 3 from “xxxx” to “yyyy”. (C11). At this time, the user level and the last updated terminal are left as they are. Thereafter, the control result is notified to OpS2 (C12). When OpS1 does not approve the update of OpS2, the control result of OpS2 is notified that the control is not approved by OpS1.

  According to this embodiment, the user level of the client can be set according to the skill of the operator, and it is possible to prevent an operational problem from being caused by an erroneous operation by an operator with low skill.
