Description

  The present invention relates to a line management system and a line management method for communication lines, and more particularly to a line management system and a line management method using a computer.

  Generally, in a line management system for a wired line or a wireless line, a corresponding management drawing is searched from a booklet or a document in which a large number of management drawings drawn in the form of drawings are printed on a paper surface, and stored in a database in advance. By referring to each data of the line and the facility installation location, the data to be updated is written in the corresponding management drawing, and the management drawing is created. And, for example, when finding a candidate for an available line in a desired section, a station equipment configuration drawing or a line accommodation breakdown in which information in each office is managed in the form of a booklet or a document This data is pulled out on the desk, and the inquiry is repeatedly made based on the drawings and data described on the paper.

  Since conventional line management has been performed as described above, there is a problem that it takes time to work on the line configuration. In addition, when configuring the line, if it is impossible to get an approximate idea of which relay station has what kind of line, the work efficiency is low, and it is necessary to rely on the experience and intuition of momentum workers. There is no problem. In order to solve such a problem, the present applicants filed an application for a computer line configuration system and a method thereof, and have already been patented (see, for example, Patent Document 1).

  In this line configuration system and method using a computer according to Patent Document 1, a database management system for storing installation locations and line master data, and each installation location and a line connecting these installation locations are displayed on the screen. It processes the data stored in the database management system based on a display device that can be used, an input device that can input desired conditions for a line to be configured between a plurality of designated installation locations, and a command from the input device. And a central processing unit 2 for displaying on the display device. In this line configuration system and method, a lower-level installation site with fewer connected lines is identified from among the selected installation locations, and an empty line that satisfies the conditions input to the input device is selected between the selected installation locations. In addition to searching for a candidate for a route connecting the lines and the line of the route, at the time of route search, the route is searched from the specified lower installation location side toward the other side.

In the above conventional computer line configuration system and method, a single transmission medium (single line) interposed between adjacent devices (for example, an exchange-telephone, a telephone-telephone, etc.) is one unit of the line configuration. It is defined as That is, as shown in FIG. 12, when a telephone line is configured, in order to register the line, according to the equipment configuration of the exchange, telephone, etc., (i) starting (starting) equipment (switch) 2, (ii) configuration A line (for example, a 1.5M transmission medium) 3 and (iii) a terminal (end point) device (telephone) 4 are registered. For this reason, even if there are many routes and lines between any two stations (two installation locations), the line can be configured easily and quickly. Thus, in the conventional line configuration system and method using a computer, the line data can be accurately managed by registering the line data, and the accommodation line can be grasped by stopping the maintenance target device, It also tries to understand the stop line when a device fails.
Japanese Patent No. 3248525 (page 7, FIG. 2)

  In the conventional line configuration system and method using a computer, the line management is realized by defining the route (propagation path) of the line configuration, thereby facilitating the stop determination process. However, this line configuration system and method do not assume the presence of a loop line in the propagation path. Therefore, in an equipment configuration having a loop form, a plurality of communication paths exist between an entry-side device (starting device) and an exit-side device (termination device).

  For example, as shown in FIG. 13, when a telephone line is configured as a propagation path between a start device (telephone) 5 and a termination device (telephone) 6, this propagation path includes a single transmission medium C1, The first loop line A LOOP001 including the starting device 5 and the second loop line A LOOP002 including the terminating device 6 are configured. The first loop line A LOOP001 and the second loop line A LOOP002 are connected via a device A installed at a certain installation location ab (for example, ab branch). In order to register a telephone line connecting the starting device 5 and the terminating device 6 with a conventional computer line configuration system, as shown in FIG. 14, the line code “C FTEL001” is divided into five routes. The line is defined and defined. For this reason, every time the designated start-end device and end-point device are changed, it is necessary to register a circuit by defining a number of routes for the routes that can be formed.

  As described above, when a loop line is included in the line configuration to be registered, the line configuration cannot be uniquely defined. Therefore, in the conventional line configuration system and method, when an equipment configuration having a loop configuration is included, every time a loop line entry side device and an exit side device are determined, the line for all possible propagation paths is determined. Must be configured. That is, in the conventional line configuration system, it is defined that the propagation path of the line configuration is regarded as a continuous single line connecting two arbitrary installation locations, and a single communication path is formed. If a line having a loop form is included in the propagation path, a plurality of communication paths exist. Therefore, if there are a large number of loop lines, the number of lines constituting the line to be registered becomes enormous and complicated, and there is a problem that the line management and the system stop determination process become difficult in practice.

For the loop line A LOOP 001, the starting device is the device C and the terminating device is the device A, and for the loop line A LOOP 002, the starting device is the device A and the terminating device is the device F. The line configuration defined by the defining program 41 is stored in the server 17 together with the line / facility information linked to the line configuration and associated with the drawing, and the line is registered.

  In the line management system according to the present embodiment, as shown in FIG. 2, the control program stored in the memory 12B includes a stop determination program 42 for determining whether or not the loop line is stopped. This stop determination program 42 is (i) when a failure notification (not shown) sent from a monitoring device (not shown) includes a loop line, or (ii) scheduled stop registration by maintenance work (see FIG. 11). When a loop line is included in the line to be stopped, the presence / absence of stop of the loop line is determined. The stop determination program 42 determines that the loop line is not stopped when one of the transmission media (sections) in the loop line is stopped, and when two or more of the sections in the loop line are stopped, It is determined that the loop line has stopped.

  Further, the control program includes a loop line included in a failure notification sent from a monitoring device (not shown), and if the loop line is determined to be stopped by the stop determination program 42, the loop program is stopped. The system automatically notifies the person. Furthermore, not only when reporting a failure, but also when performing scheduled outage registration by maintenance work, if the line to be stopped includes a loop line, and the loop line is determined to be stopped by the stop determination program 42 The system operator is automatically notified of the loop line stoppage.

  The control program includes a work stop registration program 43 for registering a planned stop due to work on a maintenance work target apparatus and a propagation path of the maintenance work section with respect to the maintenance work scheduled stop plan table. The work stop registration program 43 registers the work stop as if there is no loop line to be stopped when there is no stop for the loop line determined to be stopped by the stop determination program 42, and when there is a stop. The connection program 40 links the facility system data 15A from the database management system 15 to the loop line with a stop, and registers the stop loop line linked with the facility system data 15A as a work stop.

  In the line management system according to the present embodiment, the loop line that is automatically notified to the system operator and determined to be stopped is linked to the facility data 15A by the link program 40, and the line / line is displayed on the screen of the display device 14. Equipment information is displayed. When the system operator manually inquires the line / equipment information displayed on the screen by the input device 13, for example, at the time of failure notification, the configuration diagram or system diagram of the loop line determined to have stopped is linked program 40. Are linked and displayed. When the system operator manually inquires the line / equipment information displayed on the screen by the input device 13 when registering the scheduled stop plan for the work, the connection is established among the loop lines determined to be stopped. The line to be stopped when it is disconnected is extracted, and the line to be stopped is displayed when the transmission medium (section) is stopped.

  Next, the line management method according to the present invention will be described based on the operation of the line management system according to the above embodiment. First, as shown in FIG. 3, a desired starting device M1 and terminating device M4 are selected by the input device 3 from the system diagram or line / facility information displayed on the display screen of the display device 14, and the propagation path P (M1-M4) is designated (see step S1 in FIG. 4). When the propagation path P (M1-M4) is designated, it is determined whether or not the propagation path P (M1-M4) designated by the defining program 41 includes a loop line (see step S2 in FIG. 4). If it is determined that there is no line, the line is configured with a single communication path consisting of a series of single transmission media (see step S3 in FIG. 4). If it is determined that the designated propagation path P (M1-M4) includes the loop line LOOP1, the loop line LOOP1 itself is defined according to a single transmission medium, and the line configuration is regarded as a single transmission medium. (See step S4 in FIG. 4). For this reason, no matter how many loop lines exist in the designated propagation path P (M1-M4), the loop line is regarded as a single transmission medium. A communication path is formed, and a line configuration including a loop line can be quickly and easily performed. Therefore, line management can be realized by simplifying the line configuration regardless of the presence or absence of the loop line and the number of loop lines.

  Further, the definition program 41 determines that the loop line LOOP1 is included on the propagation path P (M1-M4), and when defining the loop line, as shown in FIG. 3, the propagation path P in the loop line LOOP1 (AC) is designated by the line entry side device A (starting end device A) and the line exit side device C (terminating device C) (see step S5 in FIG. 4), and the section (transmission medium) constituting the loop line LOOP1 Define the connection. As shown in FIG. 3, the connection of the loop line LOOP1 is defined as “A-B B-C C when all apparatuses A to D form a loop via transmission media Ca-b to Cd-a. -D DA ”(see step S6 in FIG. 4).

  Further, when the connection of the loop line LOOP1 is defined, the definition program 41 causes the signal input side device A and the signal output side device C on the loop line LOOP1 to be “starting device A constituting line LOOP1 terminating device C”. Is defined (see step S7 in FIG. 4). In this line management system, the defined line configuration is stored in the server 17 together with the line / facility information linked to the line configuration or the drawing, and the line configuration is registered as a line ( (See step S8 in FIG. 4). For this reason, even if there are many loop lines on the specified propagation path, the signal input side device and the signal output side device are specified for each loop line, and the line accommodated in the loop is easily specified. The For this reason, the line configuration for the loop line can be easily performed, and even if a large number of devices are included on the loop line, the input of the loop line constituting line is simplified, so the line management is simplified. The

  FIG. 6 shows a line master file registration flow when line registration is performed for a line having three devices A ′, B ′, and C ′ on the loop line LOOPA ′. For the loop line loop A ′ shown in FIG. 6, the devices constituting the loop are registered in advance in the equipment system data of the database management file 15A (see step S11 in FIG. 6). Next, when the starting device A ′ and the terminating device B ′ are selected and the propagation path P (A′-B ′) is designated (see step S12 in FIG. 6), the defining program 41 causes the propagation path P ( Whether A′-B ′) is a loop line is determined, and if it is determined to be a loop line, the loop line loop A ′ is defined according to a single transmission medium to form a line. Then, based on the designated start-end device A ′ and end-device B ′ by the defining program 41, the connection of the loop line is changed from “device A ′ to device B ′ line device B ′ to device C ′ line device C ′. Is defined as “device A ′ line” (see step S13 in FIG. 6), and the line constituting the devices A ′ to B ′ is defined as the “starting device” with the accommodation line registered as “phone line between device A ′ and device B ′” Device A'telephone configuration line Loop A'terminator device B'telephone "is defined, the defined line configuration is stored in the server 17, and the line configuration is registered as a line (FIG. 6). (See step S14).

  In the line management system according to the present embodiment, the control program includes a stop determination program 42 to determine whether or not the loop line is stopped. Whether or not the loop line is stopped is determined by determining whether or not two or more sections (two transmission media) are stopped for the loop line to which the device in which the failure is reported belongs. For this reason, as shown in FIG. 7, when a failure notification sent from a monitoring device (not shown) includes a loop line (see step S21 in FIG. 7), the device that has been notified of the failure by the stop determination program 42 belongs. It is determined whether or not two sections (two transmission media) or more are stopped for the loop line (see step S22 in FIG. 7), and if one of the transmission media (sections) in the loop line is stopped, the loop It is determined that the line has not been stopped (see step S23 in FIG. 7), and the stop notification is not made for the loop line system (see step S24 in FIG. 7). If two or more sections in the loop line are stopped, it is determined that the loop line has stopped (see step S23 in FIG. 7), and the system operator is automatically notified of the loop line system (FIG. 7). Step S25). Further, upon receiving the notification, the system management operator can immediately collect information on the loop line determined to be stopped and take a countermeasure, thereby improving the line management efficiency. Further, in the loop line, even if one transmission medium of all the transmission media stops, the loop line is not regarded as a line to be stopped, so that the management work is made efficient.

  Then, when the system operator confirms the notification information indicating that the loop line is stopped displayed on the screen of the display device 14 and clicks the failure information on the screen manually by the input device 3, the failure is stopped by the linkage program 40. At least one of the line / facility information and the system diagram (line configuration diagram) of the section (transmission medium) is displayed on the screen (see FIG. 8). For this reason, since the loop line determined to be stopped is linked to the database and the constituent lines of the loop line are displayed, detailed information can be obtained quickly, and line management is facilitated.

  In addition, the control program includes a work stop registration program 43, and registers a planned stop due to work on a maintenance work target device and a propagation path of a maintenance work section with respect to the maintenance work planned stop plan table. ing. For this reason, as shown in FIG. 9, when performing work stop registration for the scheduled stop plan table (see step S31 of FIG. 9), the designated propagation paths P (M1-M4), P (AC), P ( If it is determined that there is a loop line in AD), P (CF), and P (A'-B '), whether or not two sections (two transmission media) or more are stopped for the loop line by the stop determination program 42. (See step S32 in FIG. 9), if one of the transmission media (sections) in the loop line is stopped, it is determined that the loop line is not stopped (see step S33 in FIG. 9), and the work is stopped. The registration program 43 performs work stop registration for the loop line as no work stop target line (see step S34 in FIG. 9).

  When two or more of the sections (transmission media) in the loop line are stopped, the stop determination program 42 determines that the loop line is stopped (see step S33 in FIG. 9), and information indicating that the loop line is stopped. Is automatically notified to the system operator (see step S35 in FIG. 9). Then, when the system operator confirms the notification information indicating that the loop line is stopped displayed on the screen of the display device 14 and clicks the failure information on the screen manually by the input device 3, the failure is stopped by the linkage program 40. The section (transmission medium) is extracted, and at least one of the line / facility information of the loop line that has failed and its system diagram (line configuration diagram) is displayed on the screen (see step S36 in FIG. 9 and FIG. 10). Then, the work stop registration program 43 performs work stop registration for the loop line as having a work stop target line (see step S37 in FIG. 9 and FIG. 11).

  In this way, in the work stop registration program 43, when there is no stop for the loop line determined to be stopped by the stop determination program 42, the work stop registration is performed assuming that there is no loop line to be stopped, When there is a stop, the facility program 15A is linked from the database management system 15 to the loop line with the stop by the connection program 40, and the stop loop line linked with the equipment system data 15A is registered as a work stop. Yes. For this reason, when one loop of a loop line is stopped when the maintenance work is registered in the scheduled stop plan table, it is possible to register the line as if there is no line to be stopped, and the loop line stop determination process can be accurately performed. The line management can be simplified.

  In the above embodiment, the device that connects the wired and wireless lines is a telephone or an exchange. However, the present invention is not limited to this, and the same effect can be obtained even in a relay device such as a multiplex conversion device or a router device. Needless to say. Further, in the above embodiment, the defining program 41 determines whether or not there is a loop line when a starting device and a terminating device are specified and a propagation path is determined. It is determined whether or not the loop line transmission medium exists on the road. As a result of the determination, if it is determined that the loop line transmission medium exists on the propagation path, the line configuration for the loop line is configured. However, the present invention is not limited to this, and it is possible to recognize the presence or absence of a loop line for the specified propagation path, and even to recognize whether or not the transmission medium of the loop line exists. For example, after a propagation path is specified, it can be defined without going through a discrimination process.
