The present invention relates to an alarm output method using a graphic in an electronic switchgear and a system that accommodates a function of detecting and collecting alarms generated in the electronic switchboard.

In the event of an alarm during operation of the TDX-10 of an electronic switchgear, the alarms detected by the alarm detector are delivered to an alarm processing application in the Operation and Maintenance Processor (OMP). The alarm processing application accesses the alarm information in the OMP disk and extracts information related to the generated alarm. The extracted information is first formatted according to the output message type prepared by the developer and then transmitted to the MMP (Man Machine Processor).

The application program in charge of the message output in the MMP accesses the MMP hard disk, reconstructs the text to be actually output to the output device, and then transmits the text to the output port. I / O devices read the corresponding port and output the data as text if present.

There are a number of system states and data that operators need to be aware of in order to operate the exchange efficiently, and this information can be output by periodically testing system resources or at the request of the operator, or by storing and managing data generated during call processing. do. In particular, in case of functions that generate a lot of output messages very frequently such as alarm processing, the load of OMP and MMP is increased, resulting in an increase in exchange load.

The present invention is to provide a variety of easy understanding and expression compared to the output of the conventional text form by outputting the alarm data generated at the exchange using a computer graphics function.

In order to reduce the load of OMP and MMP, which has to format the output message every time an alarm occurs, the present invention accesses the OMP hard disk during MMP initialization and configures the shaper information on the position of the subsystem, rack position, board position, etc. And on the MMP memory of the alarm table for a possible alarm source. That is, the alarm table constructed in the MMP memory includes not only the alarm information operated in the exchange but also the position information of the rack diagram to be drawn in the screen of the computer. Therefore, whenever an alarm processing application in OMP detects a system alarm, the alarm source is sent directly to the MMP without having to access the hard disk each time and format the output message. The MMP outputs the alarm information from the alarm table in memory. Just send it to the port. The transmitted alarm information points to the relevant board in the rack by the graphic tool implemented in the computer and provides the operator with the location, type and importance of the alarm. In particular, the present invention builds an interface library for data transmission between the exchange host and the input / output devices to provide a channel through which all application programs in the exchange can directly transmit data to the input / output device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the structure diagram of the TDX-10 system, which is composed of subscriber and trunk line interface, time switch, various signaling devices, packet processor, etc., which performs most call processing functions and performs its own operation and maintenance. Switching Subsystem (101) and call processing functions such as number translation, route control function, centralized functions such as spatial switch connection, etc., are provided with a network synchronizer to generate and distribute system clocks, and ASS (101) mutual or ASS ( 101) and the overall maintenance and operation of the system (INS) 102 that connects the optical link between the CCS 103 and the optical link, the test and measurement, statistics, and the magnetic tape unit (MTU). (Cental Control Subsystem) (103) that performs control management of auxiliary storage devices, such as a disk unit (DKU)) and coordination with the operator and other systems. The input of operation command for graphic output and transmission of operation command information is performed in the MMP (Man Machine Processor) 105. The MMP is a processor that manages the linkage between the operator and the exchange application program. Personal Competer), printer, and other peripherals are connected. Application programs loaded and executed on the processors in the subsystems 101, 102, and 103 perform a corresponding function through message communication with an MMP providing matching functions with an operator, and the execution result is transmitted back to the output device through the MMP.

2 is a process configuration diagram for graphically outputting system alarms generated from an electronic switchboard. A plurality of ASPs (Access Switching Processors) are mounted in the ASS shown in FIG. 1, and each ASP is in charge of alarm detection. An AACU (Alarm Access Control Unit) 201 is present. Alerts detected in each ASP are sent to the OMP, and the alert processing application 202 in the OMP sends the alert information to the MMP. The MMP is sent, and the alert processing application 202 in the OMP sends the alert information to the MMP. The MMP accesses the OMP hard disk at processor initialization and builds a new alarm table in memory for subsystem location, rack location, board location, etc. on the actual computer screen for each alarm source (203). That is, the alarm table constructed in the MMP memory includes not only the alarm information operated in the exchange but also the position information of the rack diagram to be drawn in the screen of the PC. After extracting the location information in the computer screen of the transmitted alarm from the alarm table built in the memory transmitted from the OMP to the MMP (204), and transmits to the port through the interface library established for communication between the exchange and the computer (205). . The transmitted alarm information points to the corresponding board in the rack by the graphic tool of the computer and provides the operator with the location, type, and importance of the alarm (206).

3 shows the communication procedure required for RC232C communication between MMP and computer, and the communication procedure and contents are as follows.

Alarm output start request (301) (MMP → Computer)

Ask the computer for a graphic output of the alarm.

-Alarm output ready (302) (Computer → MMP)

The computer's graphical tool informs the MMP that it is ready to receive the alert information sent.

Subsystem and rack information transmission (303) (MMP → Computer)

What subsystems make up the exchange and what racks make up each subsystem sends information per subsystem. The information transmitted together is the name of the subsystem, the location of the subsystem in the exchange schematic, the number of racks in the subsystem, and the name and location of each rack.

Board information transmission (304) (MMP → Computer)

Information on the alarm target boards in each rack is transmitted in units of shelves. The information sent together is subsystem location, rack location, shelf location, board name and location within the shelf.

-Completed receiving exchanger shaper information (305) (Computer → MMP)

Informs the MMP that all exchange rack geometry information sent from the MMP has been received.

Alarm source transmission (306) (MMP → Computer)

The location information of the generated alarm is extracted from the alarm table built in MMP and transmitted to the computer. The information sent together is the location of the subsystem issued by the alarm, the location of the rack, the location of the shelf, the location of the board, the contents of the alarm, and the importance.

-Alarm transmission end notification (307) (MMP → Computer)

Notifies the computer of the end of the graphical alarm output.

-Alarm output end request (308) (Computer → MMP)

It is required to stop the transmission of alarm information.

4 is a table containing information related to the rack shape among the alarm tables in the memory constructed at the time of MMP initialization. The shape table constructed by accessing the OMP hard disk has a tree structure to facilitate initial graphic output and search of the alarm source table when an alarm occurs. Each subsystem 401 constituting the exchange rack includes a name, a unique number, a location, and information on one or more alarm access control board assemblies (AACAs) 402 that are responsible for alarm control of the corresponding service system. . The AACA information is the name, location, indexes 403 and 404 for quick retrieval of the alert source table shown in FIG.

FIG. 5 is a hash table including information of all alarms that may occur during operation of the exchange, and the search for alarms generated in a specific rack may be performed using the indexes 501 of FIG. 4 as a key. Included are alarm source number, name, alarm code, importance, shelf number, and board position within the shelf.

6 shows that the application program in the MMP receives input commands from the alarm processing program and the command execution control application in the OMP (601) to output the alarm information graphically, and then requests the process ID of the alarm processing application program to the OMP. (602). After receiving the process ID (603), the drive request message is transmitted (604) to a computer graphical tool. After receiving a message indicating that the preparation is completed from the computer (605), the preparation for transmitting the shape information is performed.

FIG. 7 is a flowchart for transmitting shape information to represent an alarm generated during operation of an exchange on a rack configuration diagram of an exchange that actually operates.

First, information on the subsystem constituting the switch shaper is transmitted to the computer (701). Once the information of one subsystem is transmitted, the information on the alarm target boards in the racks constituting the subsystem is transmitted in units of shelves (702). After transmitting information about all racks in one subsystem, information about the next subsystem is repeatedly transmitted (703) (704). After all the shaper information has been transmitted, the computer is informed that the shaper display is complete (705) and waits for transmission of the generated alarm source (706).

8 is a flowchart of a process in which an MMP application communicates with an OMP alert processing application and a computer graphics tool. If a message indicating that an alarm has occurred is transmitted from the OMP alarm processing application (801), it is checked whether a delay of transmission of alarm information currently transmitted from the OMP has occurred (802). If a transmission delay occurs at this time, an information transmission end request message is transmitted to the OMP (803), and the computer output end request (804). However, if no transmission delay has occurred, it is checked 805 that the transmitted information is valid. If the information is valid, information on the transmitted alert is extracted (806) from the alert source table constructed in the MMP memory and transmitted (807) to the graphic tool of the computer. If invalid information is transmitted, the process is processed in the same manner as in the case where a transmission delay occurs (808). If the waiting MMP application has been informed by the OMP's alarm handling application that an abnormal condition has occurred, information transmission is not possible (809), requesting the computer to terminate the graphics output (810). In addition, the operator may terminate the graphic output when desired, and the MMP application is notified that the graphic output is terminated (811). After requesting to terminate the transmission of the information, the MMP application program outputs an end message and terminates execution of the command (813).

9 is a functional flow diagram illustrating how a graphical tool of a computer performs message communication with an MMP application in an exchange. The computer checks 901 what messages have been sent from the MMP application. If the message requesting to run the graphical tool (902), the graphical tool initializes the data structure or buffers (903), then opens the main window and waits (904). If a message about an alarm source has occurred (905), the corresponding shelf of the alarm generating rack in the main window is displayed in a different color and displayed (906). If the subwindow of the rack is open, it displays up to the board level in the shelf. (907). In addition, the operator may perform graphic output termination from time to time. In this case, the graphic tool destroys all the generated resources (908), and destroys all open windows (909, 910), and then notifies the MMP application that the graphic output has ended (911). When the waiting graphics tool receives the end request message from the MMP (912), all of the generated resources and windows are destroyed (913) (914) (915) and the graphics output function ends.

The present invention configured and operated as described above is applicable to not only an electronic switch but also other similar systems operating in real time, by providing the operator with easy understanding and quick visual recognition as graphic information instead of textual alarm information. More efficient operation can be guaranteed. In addition, the present invention provides an interface library for data transmission and reception between the exchange and the computer, thereby providing a method for all application programs in the exchange to transmit desired data to the computer.
