Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation monitoring device for a partner processing device between two or more processing devices having communication functions with each other, and in particular, the partner processing device is a self-processing device. The present invention relates to a monitoring device that determines whether or not communication is possible between the monitoring devices.

〔Overview〕

According to the present invention, in an operation monitoring device of a partner processing device between a plurality of processing devices having communication functions, general data is also used as a part of the operation monitoring control data,
Even if the transmission / reception of operation monitoring control data is temporarily interrupted, the other processing device is not considered as incommunicable while general data can be sent / received to prevent fault detection due to misidentification, and to improve the reliability of the operation monitoring function. It is intended to improve accuracy and increase the operating rate of the processing equipment.

[Conventional technology]

Conventionally, the operation monitoring of this type of partner processing device involves converting the data communicated between the partner processing device and its own processing device into health check control data and other general data for the purpose of monitoring the operation of the partner processing device. The operation status of the partner processing device was monitored only by clearly categorizing and monitoring the transmission and reception of health check control data.

[Problems to be solved by the invention]

In the above-mentioned conventional device, due to a high load of various resources of the partner processing device, a heavy load of communication traffic of general data between the partner processing device and the self processing device, or loss of health check control data, the health of the self processing device is reduced. A check monitoring data reception monitoring time-out occurs, and there is a drawback in that the partner communication processing device is mistakenly considered to be in a communication-disabled state even though communication with the partner processing device is possible.

The present invention prevents fault detection due to erroneous recognition by preventing the other processing device from being incommunicable while general data transmission / reception is possible even if transmission / reception of health check control data is temporarily interrupted, and health check monitoring is performed. The purpose is to improve the reliability and accuracy of the control function and increase the operating rate of the processing equipment.

[Means for solving problems]

The present invention is directed to communication processing means for controlling transmission / reception of health check control data for monitoring the operating status of a communication partner processing apparatus and general data and a partner processing apparatus, and receiving from the partner processing apparatus via this communication control means. In the operation monitoring device of the partner processing device, which comprises a health check monitoring control means for monitoring the operation status of the partner processing device from the health check control data, a general data transmission / reception request is sent to the communication control device and Data transfer control means for detecting completion of transmission and reception, and means for generating pseudo health check control data corresponding to the health check control data received from the partner processing device according to the detection output of the data transfer control means, The health check monitoring control means uses the pseudo-health check control data to detect the other party. It is characterized by including means for activating the monitoring of the operation of the processing device.

[Operation] The operation monitoring device of the partner processing device sends a framed health check inquiry signal to the partner processing device. In response to this health check inquiry signal, the partner processing device interrupts the running program, checks the health of its own processing device, and sends back its response as a frame signal.

The operation monitoring device compares this response with the reference pattern to determine whether the operation status of the partner processing device is normal.

At this time, the operation monitoring device activates the monitoring timer and determines that the partner processing device is abnormal if there is no response from the partner processing device within a specified time after sending the health check inquiry signal.

However, for example, due to high traffic load and communication,
Even if the health check control data is received, the partner processing device is not interrupted and the response may be delayed. At this time, since there is no response from the health check within the specified time, if it is left as it is, the partner processing device is judged to be abnormal although it is normal.

Therefore, in this case, the pseudo health check control data corresponding to the specified pattern is generated, and the monitoring timer is updated once more by this, so that the partner processing device is not immediately judged to be abnormal.

As a result, even if the health check control data is not received, the partner processing device is not immediately determined to be abnormal, and therefore fault detection due to erroneous recognition is reduced, and the reliability of the monitoring function is improved.
