Abstract

PURPOSE:To accurately perform the detection and the correction of abnormality and a part where the abnormality is generated by informing the generation of the abnormality when it is detected and enabling a maintenance data stored in a maintenance data memory means to be read out. CONSTITUTION:When the generation of the abnormality is detected, a watchdog part 4 applies interruption on the interruption control part 2a of a main control part 2. The main control part 2 interrupts a processing operation in execution and writes a various kinds of data which show the state of a key telephone system, etc., at the time of generating the abnormality on a maintenance data memory part 5. Next, the main control part resets the whole of the key telephone system to an initial state, and reads out the maintenance data stored in the maintenance data memory part 5, and checks the presence/absence of a display data, and displays the display data on a display device 21a, thereby, makes the display device inform the generation of the abnormality. An operator reads out the maintenance data showing the abnormality, by operation of key telephone system and detects and corrects the part where the abnormality is generated.

[Effect]

In the button telephone device of the present invention, the watchdog means detects the occurrence of an abnormality in the button telephone device, and the maintenance data storage means stores predetermined maintenance data in the button telephone device when the watchdog means detects the occurrence of an abnormality. The notification means notifies the occurrence of an abnormality when the watchdog means detects the occurrence of the abnormality, and the maintenance data reading means can read the maintenance data stored in the maintenance data recording means.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. The key telephone device of this embodiment includes a main controller 1 and a plurality of key telephones 21 to 2N connected to the main controller 1.
It is composed of.

The main control device 1 includes a main YI control section 2 having an interrupt control section 2a, a telephone interface section 3, a watchdog section 4, and a maintenance data storage section 5.

The main side? The 11 section 2 controls the operation of the entire key telephone device, and also controls storage of maintenance data and notification of an abnormality when an abnormality is detected.

The telephone interface section 3 is connected to the main control section 2 and the key telephones 11121 to 2N, and provides an interface between the two.

The watchdog section 4 monitors the operation of the key telephone device to detect the occurrence of an abnormality, and is connected to the interrupt control section 2a of the main control section 2.

When this watchdog section 4 detects the occurrence of an abnormality in the key telephone device, it supplies an interrupt signal to the interrupt control section 2a to interrupt the main control section 2, and causes the main control section 2 to perform an abnormality processing operation. It has the function to

The maintenance data storage section 5 is connected to the main control section 2,
When an abnormality occurs, predetermined maintenance data is written from the main side 71 section 2.

At least one of the plurality of button telephones 21 to 2N
The key telephone set is a maintenance key telephone set that has a display device for notifying the occurrence of an abnormal operation.

Hereinafter, this button telephone for maintenance will be referred to as a button telephone 21, and the display device included in this button telephone 21 will be referred to as 21.
This maintenance key telephone [21, indicated by a], reads out maintenance data stored in the maintenance data storage section 5 by operating its buttons, and displays it.
It also has a function to display on a.

Referring to FIG. 2 fa+, the abnormality processing operation by the main side jJ section 2 consists of a current processing interruption step 110, a maintenance data writing step 120, and a system reset processing step 130.

Referring to FIG. 2 (bl), the system reset processing step 130 in FIG. 2+al further includes the initialization processing step 7.
210, a display data presence/absence check step 220, and a display control step 230 for the key telephone.

Next, the operation of the key telephone device of this embodiment configured as described above will be explained.

When the watchdog section 4 detects the occurrence of an abnormality while monitoring the operation of the key telephone device, the watchdog section 4 issues an interrupt to the interrupt control section 2a of the main control section 2. The main control unit 2 executes an abnormality processing operation in response to this interrupt.

In this abnormality processing operation, the main control unit 2 first interrupts the processing operation currently in progress (step 110), and collects various maintenance data indicating the state of the key telephone device at the time of occurrence of the abnormality, such as the time of occurrence of the abnormality. , Necessary maintenance data such as the connection state of the call at the time of occurrence, the state of the main circuits, data indicating system reset, and data displayed on the display device 21a of the key telephone 21 after the initialization process (step 210) are stored as maintenance data. The data is written into the storage unit 5 (step 120).

Next, the process proceeds to system reset processing (step 130), where the main control unit 2 performs the same initialization processing as conventionally performed, and resets the entire button telephone device to its initial state (step 210). When the initialization operation is completed, the main control section 2 accesses the maintenance data storage section 5, reads out the maintenance data stored in the maintenance data storage section 5 in step 120, and checks whether there is display data (step 220).

When display data exists, the display data is transmitted to the button telephone 8!21 equipped with the display device 21a via the telephone interface section 3, and this display data is sent to the display device 2.
La (step 230) to notify the occurrence of an abnormality.

By visually displaying the display data on the display device ff121a of the button telephone 21 in this way, the display device 2
The operator of the key telephone 21 who notices the display at 1a can immediately or later recognize that an abnormality has occurred in the key telephone device and the system has been automatically reset.

After confirming the display indicating the occurrence of an abnormality, the operator of the button telephone 21 reads out the maintenance data indicating the abnormality at the time of occurrence stored in the maintenance data storage unit 5 by pressing the button of the button telephone R21, and performs the maintenance. data button phone 21
By displaying the maintenance data on the display device 21a and analyzing the displayed maintenance data, abnormalities can be detected and repaired.

By the way, when the operator of the button telephone device forcibly resets the device, it is distinguished from a system reset performed due to the occurrence of an abnormality, and the display data is not displayed on the display device 21a of the button telephone [21]. In order to avoid
When reading and retrieving maintenance data (step 220), only the data stored in the maintenance data storage section 5 and displayed on the display device 21a of the key telephone 21 may be cleared.

In the above embodiment, a specific key telephone equipped with a display device is used as a key telephone for maintenance, and the key telephone displays the occurrence of an abnormality and reads maintenance data. A maintenance device different from the above may be provided, and the maintenance device may display the occurrence of an abnormality or read maintenance data.

〔Effect of the invention〕

As explained above, the present invention notifies the occurrence of an abnormality when the occurrence of an abnormality in the button telephone device is detected, but also allows the operator of the button telephone device to inform the user of the presence or absence of an automatic system reset due to the occurrence of an abnormality. It has an effect that can be clearly communicated.

In addition, by saving predetermined maintenance data and making it possible to read the saved maintenance data, it is possible to know the history of the button telephone device based on the read maintenance data, which allows you to analyze the cause of abnormalities and This has the effect of allowing spotting and repair to be performed accurately and quickly.
