Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a system status display method in an electronic exchange, and in particular to the operation of a plurality of type 1! type input/output devices constituting an electronic exchange and a central control unit that controls them. The present invention relates to a system status display method that constantly displays the status and also displays which device caused the failure when a failure occurs.

[Conventional technology]

The conventional system status display method for electronic switching equipment, which consists of multiple types of input/output devices such as main storage, hard disk control, and common line signal line control, and a central control unit that controls them, simply displays the status of each device. It had a simple configuration that displays and controls only an element that displays whether the power source is on or off and an element that displays that the system has been removed from the system configuration due to a failure or the like.

[Problem that the invention seeks to solve]

Therefore, there is a drawback that it is impossible to know whether each device is operating normally or not just by looking at the display elements as described above. In addition, even in conventional electronic exchanges, the central control unit is equipped with a system status display output function that displays on a CRT etc. whether each device in the system is operating normally. It is possible to have the system itself tell you the operating status by using the system status display output function etc. using the input/output device, but this is time consuming and may make it impossible to confirm the normal operating status. There is. In other words, as shown in Figure 6, which shows the conventional procedure for confirming normal operating conditions, when confirming whether the system is providing services normally, first check the inside of the casing cover of each input/output device in the system. Step 56: Check the power lamp of the device, etc., and make sure that the device in question has not been removed from the system configuration.
1) Next, the system's man-machine interface input/output device activates the system status display output function of the central control unit to check the system operating status. Similarly, it is necessary to check the line status using the line status display output function of the device (step 563), which is time-consuming and requires a lot of effort from the input/output device for the central control unit and man-machine interface. In the event of a failure, it is impossible to activate the above functions and confirm the normal operating state.

Furthermore, in electronic exchanges with a single configuration that do not have alternative equipment, the system is automatically restarted and fault information is output to the input/output device for the man-machine interface. In situations where it is impossible to restart the system by itself, such as when a fixed failure occurs, the above failure information is not output, and therefore maintenance personnel must check all input/output devices in order to identify the failure device. Therefore, it is necessary to identify the faulty device by performing a device test or replacing the device, and the time it takes to identify the faulty device delays the provision of replacement services, which causes great inconvenience to users.

FIG. 7 is a flowchart showing an overview of conventional processing from the occurrence of a failure to system establishment. When a device failure occurs, the system failure processing in step S71 identifies the device that was operating at the time of the failure or the faulty device. The system saves detailed information on the failure, such as the situation when the failure occurred, to the system failure information storage area, and then initializes the system hardware using the system's own system restart function (step 372). By the system restart processing function of the system restart function, the central
The internal information of the 0B device is initialized (step 57).
3) Next, the restart processing function initializes the device management function of each input/output device for data and devices in order.Step 574) After all devices have successfully completed initialization, store it in the system failure information storage area. The failure information that has been displayed is output to the man-machine ink face input/output device and notified to the maintenance personnel (step 375).

On the other hand, FIG. 8 shows the flow of the process shown in FIG. 7 when the system goes down due to a fixed failure of the device, together with the flow of operations conventionally performed by a maintenance person at that time. If a situation that cannot be recovered by the system itself, such as a fixed failure, occurs, steps 371 to 3 in FIG.
Processing similar to 74 is performed, the fault information is stored in the system fault information storage area, and an attempt is made to restart the system. Since a failure occurs again during the initial settings, steps 871 to 374 for storing failure information and initializing various devices will be repeated until the failure is repaired, and step S75 will not be executed. , the fault information stored in the system fault information storage area will not be output from the man-machine interface input/output device. Therefore, the maintenance person stops restarting the system, tests each device in order starting from the central control unit, and replaces the device as necessary (step 581). When the faulty device is identified, it is replaced with a normal device (step 581). A series of operations are performed including step 582), system restart and confirmation of system establishment (step 583). In this way, when a fixed failure occurs in a certain device and a situation occurs where the system itself cannot recover, maintenance personnel must carry out device tests and device replacement for all devices in order to identify the faulty device, as described above. Therefore, it takes a lot of time to identify the faulty device, and the provision of replacement service is delayed.

The present invention solves the above-mentioned conventional drawbacks, and its purpose is to eliminate the problem even if the central control unit or the input/output device for the man-machine ink face does not function properly.
It is possible to visually check the operating status of each component of the electronic exchange, and if a failure occurs in the equipment, the system can visually check the failed equipment even if it is impossible for the system to recover by itself. An object of the present invention is to provide a system status display method in an electronic exchange that can be confirmed more quickly.

[Means for solving problems]

In order to achieve the above object, the present invention provides a system status display method for an electronic exchange including a plurality of types of input/output devices and a central control unit that controls the devices, and provides a system status display method for displaying the presence or absence of a failure in each of the input/output devices. a system status display device having a display element disposed on a front panel; and a status display element for displaying the operating status of the central control unit and each of the input/output devices; and controlling the lighting of the corresponding status display element according to the operating state of each of the input/output devices, and when a failure occurs in the input/output device, the failure display corresponding to the input/output device in which the failure has occurred. The device is configured to illuminate the element.

[Effect]

During operation of the electronic exchange, the lighting of the status display elements corresponding to the central control unit and each input/output device is controlled according to the operating status of the central control unit and each input/output device. When this occurs, a fault display element on the front panel of the system status display device corresponding to the input/output device in which the fault has occurred is lit.

Next, the status display elements GO to G12 . of the system status display device 11 corresponding to each device are displayed. A method of controlling the fault display element RO-R12 will be explained.

Control method of the status display element GO compatible with the central controller LL] The display state of the status display element GO compatible with the central controller 1 is controlled by performing system status display setting processing on the wjm function on the execution side of the system at a cycle of, for example, 500 ms. This is realized by, for example, alternately operating the drive circuit of the status display element GO of the system status display device 11 to turn on and off via the bus 2. Therefore, when the central control device 1 is operating normally, the status display element Go will blink, and if the central control device 1 is not operating normally for some reason, the status display element GO will turn off. Or it will stay on.

When the G9 receives an input request from the central control device 1,
Alternatively, when an output request occurs, the central control unit 1 operates the drive circuits of the status display elements corresponding to the devices of the input request destination and the output request destination to the lighting side, and when the input request processing and output request processing are completed, the above-mentioned The drive circuit is controlled to turn off the lit state display element. Therefore, the packet line control bag 210°, 10. .

Note that the packet line control device 10°, 10. , to
,,The central control unit 1 detects that there has been no input/output request for the common line signal line control unit 9 for several seconds, and upon this detection, the system execution control of the central control unit 1 performs an invalid operation (usually a health check). If it is normal, the status display element corresponding to the device may be turned on for a short period of time.Such control is normally used only for a certain period of time when the device does not operate much. ,
Alternatively, it is also applicable to devices that operate only once a day.

As described above, each of the status display elements GO to G12 on the system status display device 11 indicates the operating status of the central control unit l and all input/output device systems, so the operator can simply look at these displays. You can easily check the operating status of the system, including the load status.

[Control method for fault display elements RO to R12 corresponding to each device] The fault display elements RO to R12 corresponding to each device correspond to the fault device when storing fault information in the system fault information storage area when a fault occurs. Fault display element RO~R1
This is done by operating the drive circuit No. 2 to the lighting side, that is, as explained in FIG. 8, when a device failure occurs,
In the system failure processing in step S71, the device that was operating at the time of the failure or the failed device is identified and detailed information about the failure, such as the situation when the failure occurred, is saved to the system failure information storage area. Then, at the same time, the fault display element corresponding to the faulty device on the system status display device 11 is turned on.

Note that the illuminated fault display element is turned off at the time of fault recovery, such as when reporting the fault in step 375 of FIG. 8, for example.

For example, if a failure occurs in the main memory unit (MM#0) 4o, the failure information is stored in the system failure information storage area, and the system status display device 11
The fault display element R1 lights up.

Thereafter, as shown in FIG. 8, the system hardware is initialized by the system restart function by the system itself (step 572), and then by the system restart processing function of the system restart function. The internal information of the central control unit 1 is initialized (step 573), and then the device management function of each input/output device is initialized by the restart processing function (step 574).
If the fault in the main storage unit 4° is a fixed fault or the like, and if the fault in the main storage unit 4° is detected again during the system restart processing function by the system itself, step 75 will not be executed, resulting in a system failure. The fault information stored in the information storage area will not be notified to the maintenance personnel.

However, in this embodiment, since the system status display device 11 displays that the main storage unit 4° has failed, the operating procedure of steps 381 to S83 in FIG. 8 is replaced with the procedure shown in FIG. A faulty device can be identified by simple operations as shown. That is, first, the maintenance person identifies that a fault has occurred in the main storage unit 4° using the fault display element of the system status display device 11 (step 551), and identifies this main storage unit 4° as the suspected faulty device. Replace with a normal device and restart the system (step 552). Then, it is checked whether or not the system has been established by checking the status display element of the system status display device 11 (step 353).
As described above, in this embodiment, since the suspected faulty device can be identified at a glance by the fault display element of the system status display device 11, the number of device tests and device replacements is drastically reduced, and the time required to restart replacement service is reduced compared to the conventional method. 1/3 to 1 compared to
/ It can significantly regress to 4th place.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various other additions and changes are possible.For example, the following changes are possible.

■In the above embodiment, the status display element GO is provided in the central control unit 1.
and a fault display element RO are provided, but the fault display element RO is omitted.

■In the above embodiment, status display elements 01 to G are displayed on the front panel of the system status display device 11 corresponding to each input/output device.
12 and fault display elements R1 to R12, but for example, only fault display elements R1 to R12 are provided on the front panel,
The status display elements 01 to G12 are provided at different locations such as inside the cover of the housing 20.

[Effects of the Invention] As described above, according to the present invention, during operation of an electronic exchange, the status display element corresponding to the central control unit and each input/output device is displayed depending on the operating status of the central control unit and each input/output device. Since the lighting control is performed, there is no need to use the man-machine interface input/output device as in the past, and even when there is an abnormality in the man-machine interface input/output device, the system operating status of the electronic exchange can be maintained. This has the effect of allowing you to recognize Vfl at a glance.
