Description

[Detailed description of the invention]

The present invention relates to a scheduled maintenance system in which maintenance commands to be activated and executed can be registered in advance in a storage program controlled electronic exchange (hereinafter simply referred to as an electronic exchange). There are typically nine types of maintenance commands for electronic exchanges as shown in the table below.

[Table] These commands must be performed periodically depending on their contents, so the commands are often reserved and registered. FIG. 1 is a system configuration diagram of an example of a conventional scheduled maintenance system. In this conventional system, first, when a maintenance person issues a maintenance command reservation/registration instruction from a typewriter, the data is given to the central processing unit via a data channel. Based on this information, the central processing unit displays it in a table on the main memory and makes reservations and registrations. Figure 1 shows, for example, the maintenance command ALT (No.
2) When the startup time is commanded to be 18:50, at that time, the #18th word of the table HOUR and the #50th word of the minute table MIN are displayed (“1”) in the bit corresponding to the command. something is shown. The central control unit monitors the registered time, and when it detects and identifies that the time has arrived, it starts and executes the maintenance command ALT with predetermined contents. This conventional method relies on bit display control of a time table that specifies only the start time of a maintenance command, and therefore has the following disadvantages. (1) When a maintenance command is executed, if the bit display related to the command specification is reset, subsequent execution of the command will become impossible.Also, if the above bit display is left set, the bit display related to the command specification will be reset at the same time every day. The command will be executed repeatedly. In other words, it is not possible to repeat the execution of the command an arbitrary number of times at any desired period. (2) The registration status of maintenance commands cannot be easily displayed because the command name and registration time and minute must be calculated and edited from the bit display position of the time and minute table. Therefore, in order to obtain registered command information, maintenance personnel have no choice but to directly dump the time table and read the machine language, making it extremely time-consuming to understand the situation. An object of the present invention is to eliminate the drawbacks of the prior art described above, and to enable maintenance commands to be activated on a desired date, time, and minute.
It can be repeated a specified number of times in a period, and
The purpose of the present invention is to provide a scheduled maintenance method that can also display command registration status. The present invention is characterized by a scheduled maintenance system in which maintenance commands for storage program controlled electronic exchanges are executed at specified times according to pre-registered maintenance command activation information. Maintenance command activation information consisting of due date, time, number of repetitions, and cycle is registered in the peripheral storage device, and the information on each registered maintenance command activation that should be executed according to the elapsed time is controlled by the time monitoring and control of the central control unit. are sequentially extracted, and based on this, an instruction to execute the maintenance command is given to the central control unit itself or to the central control units of other electronic exchanges related to the centralized maintenance, and the maintenance command activation information is also extracted. This is a scheduled maintenance method in which other information to be updated included in the maintenance command activation information is updated based on the cycle information included in the maintenance command activation information. Embodiments of the present invention will be described below based on the drawings. FIG. 2 is a system configuration diagram of an embodiment of the scheduled maintenance system according to the present invention, and FIG. 3 is a registration memory configuration diagram thereof. Here, 1 is a central control unit, 2 is a main memory, 3 is a data channel, 4 is a peripheral storage device, 5 is a typewriter, 6 is a display device, and 7 is a modem. In centralized maintenance, execution instructions for maintenance commands can be sent to other electronic exchanges via the modem 7, but only one is shown in FIG. 1 to represent a plurality of them. First, the station name, content (maintenance command name), date (month/day), time (hour/minute), number of repetitions, and cycle related to maintenance command activation information are input from the typewriter 5 to the central controller 1 through the data channel 3. Ru. Thereby, the central control device 1 activates and executes the command registration program, and registers the maintenance command activation information by writing it into the free command registration area of the peripheral storage device 4 via the data channel. In the peripheral storage device 4, a desired number (for example,
It has a command registration area (for example, 32 items #0 to 31) for maintenance command startup information (32 items),
The number of bits corresponding to that number (for example, #0 to 31
32 bits) is provided to indicate whether the area is vacant or occupied. Bits #0 to 31 of this area empty/occupied display correspond to command registration areas #0 to 31, respectively, and “0” is displayed for empty areas and “1” is displayed for occupied areas. has been done. Therefore, the central control unit 1 checks this display bit and writes the designated maintenance command activation information into the vacant command registration area. For example, FIG. 3 shows the registration memory configuration related to maintenance command activation information of the peripheral storage device 4, and the station name is stored in the #0 command registration area.
AMA (example of a proper noun), maintenance command name ALT
(For example, the one in Table No. 2 above), Start date: December 31
day, startup time 23:59, number of startups 12 (remaining), startup cycle 24 hours is written in the same code used in typewriter 6 (for example, ISO code), and the area is empty and blocked.
The case where "1" is displayed in bit #0 is shown, and the same is true for other areas #1 to #31. The central processing unit 1 executes a predetermined cycle (for example, 1
(minute), start the time monitoring program in the main memory 2, check the month, day, and time at that time with the startup month, day, startup time, and minute in the peripheral storage device 4 described above, and if there is a match, the relevant maintenance command Extract and import the startup information (for example, from area #0), and if the station name belongs to it,
The relevant command execution program (for example, the one related to the maintenance command ALT) is retrieved from the main memory 2, and when it is executed, and the station name is that of another station, the relevant command execution program is sent to the central control unit of the other electronic exchange through the modem 7. Transfers maintenance command startup information and instructs execution of the maintenance command. Note that each piece of information in the command registration area is updated in preparation for the next activation. For example, the third
In the example shown in the figure, the startup date is January 1st, the startup time is also 23:59, the number of startups is 11 times, and the startup cycle is the same 24 hours. At this time, if all the activations have been completed, the command registration area is blanked and the corresponding area empty/occupied display bit is set to "0". Furthermore, as is well known, the maintenance command activation information registered in the peripheral storage device 4 can be displayed and recorded on the display device 6 or on the typewriter 5 by inputting a predetermined display command from the typewriter 5. can. Furthermore, the system configuration shown in FIG.
Not only for electronic exchanges that require intensive maintenance;
It is clear that the present invention can be applied as is to those that perform independent maintenance or those that perform only centralized maintenance without performing replacement operations (for example, centralized maintenance centers). As described above in detail, according to the present invention, by first registering the desired maintenance command activation information, the desired maintenance command is automatically executed, and the registration status is also displayed on the display. Therefore, a remarkable effect can be obtained in greatly reducing the number of man-hours and ensuring execution of maintenance work for electronic exchanges.
