Further, in the invention according to claim 3, in the normality monitoring device of the external information processing device according to claim 2, the diagnosis result information output means is provided for diagnosis by stopping the operation of the external information processing device. The diagnostic stop information output means for outputting a control signal indicating stop is provided, and the control signal analysis means is configured to operate the timer when the control signal indicating stop of diagnosis is output from the diagnostic stop information output means. The timer stop means for stopping the monitoring of the elapse of a predetermined time is provided.

[0009]

In the invention according to claim 1 configured as described above, the diagnosis result information output means provided in the external information processing apparatus diagnoses whether or not there is an abnormality at predetermined intervals and determines a predetermined value according to the diagnosis result. The control signal analysis means notifies the electronic exchange of the abnormality of the external information processing device when the control signal analysis means outputs no control signal indicating that there is no abnormality within a predetermined time from the diagnosis result information output means. ..

Further, in the invention according to claim 2 configured as described above, the timer means monitors the passage of a predetermined time in the control signal analyzing means, and the timer clearing means outputs the diagnostic result information outputting means. When a control signal indicating that there is no abnormality is input from the timer means, the elapsed time by the timer means is cleared, and the determination means periodically clears the elapsed time by the timer means by the timer clear means. When the means detects that a predetermined time has elapsed, it is determined that the external information processing device is abnormal.

Further, in the invention according to claim 3 configured as described above, the diagnosis stop information output means provided in the diagnosis result information output means stops the diagnosis by stopping the operation of the external information processing apparatus. A timer stop means included in the control signal analysis means outputs a control signal indicating the time, and when the control signal indicating the stop of the diagnosis is output from the diagnosis stop information output means, the timer monitors the elapse of a predetermined time. Since the timer is stopped, the timer and the elapse of the predetermined time are no longer monitored, so that the determination means does not determine the abnormality of the external information processing device.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electronic exchange system to which a normality monitoring device for an external information processing device according to an embodiment of the present invention is applied.

In FIG. 1, the electronic exchange comprises a switch circuit 1 for forming a communication path and a central control unit 2 for controlling the formation of the communication path in the switch circuit 1. The central control unit 2 includes an I / O device 3 for exchanging signals with an external device, and the I / O device 3 and the central control unit 2 are connected via a control bus 4.

The external information processing unit 5 stores and analyzes the information output from the central control unit 2 in the electronic exchange, and is connected to the I / O unit 3 via the serial line 6. Further, the central control unit 2 is provided with a fault indicator 7 for displaying the occurrence of a fault in the external information processing unit 5, and the central control unit 2 monitors the normality of the external information processing unit 5 to detect any abnormality. When it is detected, it is displayed on the fault indicator 7.

FIG. 2 is a block diagram showing the configuration of the I / O device 3. In FIG. 1, the I / O device 3 includes a control bus interface circuit 15 for inputting / outputting control signals to / from the control bus 4 and an output control circuit 14 for inputting / outputting signals to / from the serial line 6. ..

The control bus interface circuit 15 inputs a control signal for sending to the external device output on the control bus 4, sends the control signal to the output control circuit 14 via the sending buffer 16, and also causes the receiving buffer circuit 17 to operate. Information is input from an external device via the device and sent to the control bus 4 as an input signal from the external device.

Further, the control bus interface circuit 15
Outputs a predetermined control signal input from the scanning circuit 13 to the control bus 4 when the central control unit 2 outputs a control signal for monitoring the abnormality of the external information processing unit 5.

The output control circuit 14 outputs control signals and the like input via the transmission buffer 16 onto the serial line 6 and analyzes received information from the external information processing device via the serial line 6 in the received data. The signal is output to the reception buffer circuit 17 via the circuit 12.

The reception data analysis circuit 12 determines whether or not the signal transmitted from the external information processing device 5 is three counter control signals, and when the counter control signals are input, the counter circuit correspondingly corresponds to each of the counter control signals. Control the timing operation in 11. More specifically, when the first counter control signal is received, the counter circuit 11 is instructed to count, and when the second counter control signal is received, the count value of the counter circuit 11 is cleared and the third counter control signal is set. When received, the counting of the counter circuit 11 is stopped and the counted value is also cleared. However, when it is not the counter control signal, the received signal is output to the reception buffer circuit 17.

Scan circuit 1 connected to counter circuit 11
The counter circuit 11 stores the information when the counter circuit 11 finishes measuring a predetermined time and outputs a control signal indicating the information to the control bus interface circuit 15.

On the other hand, the external information processing device 5 outputs the first counter control signal to the I / O device 3 via the serial line 6 at the start of the operation and causes the self-diagnosis program to be executed at predetermined time intervals. If there is no abnormality, the second counter control signal is output, and when the operation is stopped, the third counter control signal is output. The execution interval of the self-diagnosis program is shorter than the count time in the counter circuit 11.

Next, the operation of this embodiment having the above configuration will be described. When the power is turned on by the maintenance person, the external information processing device 5 establishes a connection with the electronic exchange through the serial line 6, and when normally connected, a first counter control signal is sent to the I / O device 3. Is output. Then I /
In the O device 3, the reception data analysis circuit 12 recognizes the first counter control signal and outputs the same control signal to the reception buffer circuit 1.
The counter circuit 11 is instructed to start counting without outputting to 7. As a result, the counter circuit 11 clears the count value and starts counting from "0".

The external information processing device 5 activates the self-diagnosis program at regular time intervals and outputs a second counter control signal to the I / O device 3 when no abnormality is detected. Then, the I / O device 3 recognizes the second counter control and clears the count value of the counter circuit 11.

The counter circuit 11 starts counting when the external information processing device 5 outputs the first counter control signal, but the I / O device 3 does not start counting the predetermined time.
The count value is cleared by and the counting is started again from "0". While the external information processing device 5 does not detect an abnormality by the self-diagnosis program, the counter circuit 11 does not finish counting the predetermined time as described above, and the scanning circuit 13 recognizes that the counter circuit 11 finishes counting the predetermined time. do not do.

On the other hand, the central control unit 2 also monitors whether or not the scanning circuit 13 recognizes the end of the counting of the predetermined time by the counter circuit 11 by exchanging the control signal with the control bus interface circuit 15 at regular intervals. But
While no abnormality has occurred in the external information processing device 5, the recognition of the end of time measurement is not detected, and it is determined that no abnormality has occurred in the external information processing device 5.

However, when the external information processing device 5 detects an abnormality by the self-diagnosis program, it does not output the second counter control signal, so that the counter circuit 11 cannot clear the count value by the received data analysis circuit 12. Therefore, the counter circuit 11 finishes counting the predetermined time, and the scanning circuit 13 recognizes the termination of the timing. Then, when the central control unit 2 next detects the state of the scanning circuit 13, the counter circuit 11 detects that the counting of the predetermined time has finished, and the central control unit 2 indicates that an abnormality has occurred in the external information processing unit 5 and displays a fault. Display it on vessel 7.

On the other hand, when the maintenance person properly stops the external information processing device 5, the external information processing device 5 outputs a third counter control signal to the I / O device 3 before stopping the operation. .. Then, the reception data analysis circuit 12 does not output the control signal to the reception buffer circuit 17, but instructs the counter circuit 11 to stop counting and clears the counter value.

After that, since the counter circuit 11 stops counting, the scanning circuit 13 does not recognize the end of counting of the predetermined time by the counter circuit 11, and the abnormality occurs in the external information processing device 5 even in the central controller 2. Is not detected.

[0029]

As described above, according to the present invention, a predetermined control signal is periodically output from the external information processing device side, and the normality of the external information processing device is transmitted to the electronic exchange based on the control signal. The information output from the electronic exchange side to the external information processing device side is only the information to be accumulated / analyzed in order to inform the user that the input / output processing amount of each information is balanced to reduce the information processing capability. It is possible to provide a normality monitoring device for an external information processing device that can be prevented.

Further, the invention according to claim 3 provides a normality monitoring device for an external information processing device, which can prevent an abnormality from being judged on the electronic exchange side when the operation of the external information processing device is stopped. You can
