Abstract

PURPOSE:To read out information from a logical device automatically by reading out the state of the logical device by an information collector when the status of the logical device coincides with a previously set stopping condition and the logical device stops. CONSTITUTION:A condition for a maintenance man to stop the logical device 1 at a proper point of time for fault information collection at the intermittent generation of faults or the generation of an unaccoutable fault is inputted from an input part 20. In the logical device 1, the contents of a state displaying circuit 10 displaying the state of the logical device 1 are compared with that of a storage circuit 11 storing the previously set stopping condition by a comparator 12, and both the contents coincide with each other, the operation of the logical device is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a failure information collection system that collects status information of a logical device that is necessary when a failure occurs in the logical device.

[Prior art and problems to be solved by the invention] Conventionally, this type of failure information collection system connects flip-flops and flops inside a logic device as a shift register, and reads status information separately from the original operating function. It had a function called an error log that used Shift, Zos, etc. to collect and display status information of logical devices for failure analysis when a failure occurred. However, with the increasing complexity and variety of logical devices and the use of firmware, failures due to errors in addition to failures have become more common, and it has become especially time-consuming to investigate the cause of failures, especially in the case of intermittent failures that occur irregularly. . Therefore.

With the function that stops the logical device under preset conditions such as the firmware address immediately before the failure occurs, it is possible to read out the state information of the logical device at a time other than the time of the failure, for example, just before the failure occurred. By analyzing this information, it is now possible to easily determine the cause. However, when a logical device stops under preset conditions to investigate the cause of a failure, nine people have to manually read out the status information. The drawback was that it required constant attention.

[Means and effects for solving the problem] The present invention is composed of a logic device and an information gathering device, and the logic device has a condition storage circuit that stores a stop condition, and a condition storage circuit that displays the operating state of the logic device. a comparison circuit that compares the contents of the condition storage circuit with the contents of the status display circuit; a stop circuit that stops the operation of the logic device when the comparison results of the comparison circuit match; a transmitting circuit that transmits stop information indicating that the logic circuit has stopped to the information collecting device; and a state information reading circuit that reads state information of the logic device in response to a state information read request from the information collecting device. and the information gathering device includes:
an input means for inputting the stop condition; a setting circuit for setting the stop condition obtained by the input means in the condition storage circuit; It has an information collection circuit that collects the state information of the logic device read by the readout circuit, and a display means that edits and outputs the state information collected by the information collection circuit, and when a stop condition is met and the logic device is This is a failure information collection system that automatically collects status information by receiving a notification of a shutdown and collecting status information of a logical device.

〔Example〕

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention.

Figure 9 shows the failure information collection system of this embodiment.

It consists of a logical device 1 and an information collection device 2 that collects status information of the logical device 1. The logic device 1 includes a state display circuit 10 that displays state information of the logic device 1, a condition memory circuit 11 that stores stop conditions corresponding to the state display circuit 10, and a condition memory circuit 11 that stores the contents of the state display circuit 10 and the condition memory circuit 11. A comparison circuit 12 that compares the contents, and a stop circuit 1 that stops the operation of the logic device 1 when the comparison circuit 12 finds a match.
3, and a status information reading circuit 15 for transmitting the stoppage of the logic device 1 to the information collecting device 2. The information collection device 2 includes an input unit 20 for inputting a stop condition, a setting circuit 21 for setting the stop condition input from the input unit 20, and an information collection circuit 22 for collecting status information of the stopped logical device l.
and a display section 23 that displays information from the information collection circuit 22.

25 is a stop condition setting interface that writes information from the setting circuit 21 into the condition storage circuit 11; 26 is a stop sending circuit 14;
27 is a state information read interface that transfers the state information of the logic device 1 read by the state information read circuit 15 to the information collection circuit 22.

First, the operation of setting stop conditions for collecting fault information will be explained. Input section 20 indicates faults that occur intermittently.
Enter more information. For example, in the case of a logical device controlled by firmware, a specific firmware address, etc. is input, although this is not shown in Figure 1. The setting circuit 21 sets the stop condition information input from the input section 20 in the condition storage circuit 11 via the stop condition setting interface 25.

Next, the operation after setting the stop condition will be explained.

In the logic device 1, a comparison circuit 1 compares the contents of the status display circuit 10, which displays the state of the logic device 1, with the contents of the condition storage circuit 11.
Compare by 2. When comparison circuit (2) results in a match, that is, when a match between the preset stop condition and the state of the logic device 1 is detected.

The stop circuit 13 stops the operation of the logic device 1.

When the operation of the logic device 1 stops, the stop sending circuit 14 sends information to the information collecting circuit 22 via the stop sending interface 26.
The information collection circuit 22 which received the notification of the stoppage instructs the state information readout circuit 15 to start reading via the state information readout interface 27. When the status information readout circuit 15 receives the read activation, it reads the status information of the logic device 1 and sends it to the information collection circuit 22 via the status information readout interface 27 .

When the information collection circuit 22 receives the status information of the logic device 1, it transmits it to the display unit 23. The display unit 23 edits and outputs the status information.

〔Effect of the invention〕

As explained above, in the present invention, when the state of a logical device matches a preset stop condition and stops, the information collecting device is notified, and the state of the logical device is dynamically read from the information collecting device. This configuration has the effect that the information of the logical device when the stop condition is met can be read out without any manual intervention.
