Description

[Detailed Description of the Invention] [Summary of the Invention] Regarding a method for notifying an operator of an abnormality in communication data, the present invention aims to facilitate the exit of correct data by notifying the operator of an abnormality in communication data. In a communication data abnormality notification method in a system in which initial setting information is downloaded to each monitoring device and monitoring is started based on the information, each monitoring device (i) is provided with check data indicating the monitorable range and received data based on the data. A content checking unit is provided, and when the initial setting information is downloaded, each monitoring device is configured to check the content checking unit and return a response indicating whether the initial setting information is normal or abnormal, and if abnormal, indicating the location of the abnormality. do.

[Industrial Application Field] The present invention relates to a system for notifying an operator of an abnormality in communication data.

With the recent demand for the integration of computer systems, there is a need to reduce the number of maintenance personnel and to expand the maintenance area per operator.

Therefore, in systems that exchange large amounts of communication data, it is necessary to improve the abnormality notification of communication data and improve the maintenance function. [Prior Art] Figure 6 shows an example of a communication system to which the present invention is applied. In this example, the monitoring devices 1, 2, . Monitoring devices l, 2, ... are monitoring devices for communication devices located at different locations, or for devices located at the same location but different (different frequencies, different analog/digital points, etc.). be. The monitoring devices 1, 2, . . . are connected to a relay device 10 through a Lube network 12, and the relay device 10 is connected to an input/output device 11 through a line.

The monitoring device 1-n and the relay device 10 are placed in one station building, and the input/output device l1 is placed in another station building.

Conventionally, there was an input/output device 1l at the location of the relay device 10.

In other words, one operator used to operate the monitoring devices 1 to n, but in order to save labor, one operator now operates a large group of monitoring devices 1 to n, and now the system is structured as shown in diagrams. Ta. Therefore, although not shown, a plurality of relay devices for other monitoring devices are connected to the human output device 1l via lines. At the start of operation, the operator downloads initial setting information for each monitoring device, and each monitoring device receives this and starts monitoring. The initial setting information specifies the monitoring range.
Information on the configuration of equipment/equipment monitored by the monitoring device includes, for example, the number of relay stations on the wireless transmission path, the number of working/protection lines, etc. The initial setting information specifies the device that should receive it, for example, for monitoring device 1, monitoring device I! 2, etc., and the designated monitoring device receives it and returns a response, that is, if it is normal, it is normal, if it is abnormal, it is abnormal, along with its own identification information. This is shown in FIG. The response is displayed as a message on input/output device ll.

The monitoring device knows the outline of its monitoring capabilities (it has the data), such as the maximum number of stations it can monitor and the maximum number of lines it can monitor, 10. For example, if the maximum number of lines to monitor is 10 but the initial setting information is 20 and a request is made to monitor 20 lines, this is impossible and an abnormal response will occur. return it.

When there are a large number of monitoring devices and the initial setting information for each device is diverse, operator errors as described above are likely to occur.

[Problem to be solved by the invention]

As described above, in the conventional method, the response to the downloaded initial setting information is notified to the operator using a normal/abnormal message. There were only two types of response messages: normal and abnormal, and if even one part of the large amount of communication data was abnormal, it was considered ``abnormal.'' Therefore, among the large amount of normal data,
The operator cannot determine which data is abnormal.
All you have to do is check everything and find any errors.

The present invention aims to improve the above-mentioned problems and to facilitate the transmission of correct data by notifying the operator of abnormalities in communication data.

[Means to solve the problem]

As shown in FIG. 1, in the present invention, as a response to communication data (initial setting information) from the input/output device to the monitoring device, in addition to normal/abnormal information, detailed information indicating the abnormal location of the communication data is added. do. The initial setting information includes information part A which is a data group for the relay device, information part B which is a data group including identification numbers of individual monitoring devices, etc., and information part which is the number of stations to be monitored and a data group for each station. C, and an information section D which is the number of times to be monitored and a data group for each line. The response from the monitoring device is normal/abnormal, and if abnormal, information department A, B,
It is possible to use data indicating which part of...

[Effect]

In this way, in the present invention, detailed information indicating the abnormal part of the communication data is added as response information, so in the case of an abnormal response, the operator can immediately know the abnormal part of the communication data from the detailed information and correct the part to correct it. Communication data (initial setting information) can be sent to the monitoring device (if an abnormality is pointed out, the operator can easily determine what the correct data is), thereby speeding up startup.

〔Example〕

FIG. 2 shows the configuration of the parts related to the present invention of the monitoring device 1 (1"l+1+...). As shown in the figure, there are a data receiving section 2l, a received data sorting section 22, a content checking section 23,
It has a response information creation section 24 and a data transmission section 25. The monitoring device i has built-in check data, and the content checking unit 23 compares the received data (initial setting information) with the check data to determine normality/abnormality. The check data indicates the capability limits and characteristics of the monitoring device in question, and the monitoring range specified by the initial setting information should be within the range of the check data. Initial setting information that exceeds this range is considered abnormal and may be considered by the operator. Here are the instructions.

The content checking unit 23 checks whether the content is within the above range and determines whether it is normal or abnormal. This check is performed by a checking program.

Note that the data receiving section 21 receives data from the loop network, and the received data sorting section 22 determines whether the received data is a message whose contents are to be checked, and if it is a message whose contents are to be checked, it is passed to the contents checking section 23. The content checking unit 23 checks whether the received data is within the upper/lower limit range of the check data, but also checks the relevance of each data. For example, it is normal for data B to be 1 to 5 when data A is 1, but a check is made to see if this is the case. The response information creation section 24 creates response data based on the check result, and sends it to the data transmission section 2.
5 sends this to loop network l2. FIG. 3 shows an example of initial setting information and responses thereto.

The initial setting information has information parts A, B, C, and D, and the information part A
Header L, that is, various data for the relay device, information section B
is the header 2, that is, various data for each monitoring device.

The information section C contains the number of repetitions, that is, the number of stations, and various data for each station 1-n, and the information section D contains the number of repetitions, that is, the number of lines, and various data for each line 1-n. For example, if the 10th byte from the beginning of information section 8 is abnormal (outside the range of check data), the response is set to information section A, 1o. Also, if the data at the 35th byte from the beginning of information part B is abnormal, it is set as information part B, 35. Also, (2) If the 15th byte from the beginning of the data of station 1 in information section C is abnormal, the information section c,'dk is returned to several stations l, 15. Furthermore, if the 12th byte from the beginning of the data on line n of information section D is abnormal, information section D repeats in, 12 several times.
, and so on.

Figure 4 shows the data structure of the information sections A, B, C, etc., and Figure 5 shows the format of the response signal. As shown in the figure, the response signal is either normal or abnormal, the information division is A, B, etc., and the station classification is station I, station 2.
,... The abnormality consists of the number of bytes from the beginning. For example, data A in Figure 4
When 2 is abnormal, the normal/abnormal column will be "abnormal," the information section section will be "information section A," the station section section will be blank, and the number of bytes from the beginning column will be "r2." Also, when data Bn in Figure 4 is abnormal, the normal/abnormal column is "abnormal", the information section section is "information section B, the station section section is blank, and the number of bytes from the beginning column is "
n”.

In addition, when data C station l2 in Figure 4 is abnormal, the normal/abnormal column is "abnormal", the information section section is "information section C", the station section is "1", and the number of bytes from the beginning column is If it becomes "2" and data C station n1 is abnormal, the normal/abnormal column is "abnormal".
, the information section section column is "Information section C," the station section section is "n," and the number of bytes from the beginning column is "IJ."

〔Effect of the invention〕

As explained above, in the present invention, each monitoring device checks the downloaded initial setting information against the check data and returns a response indicating whether it is normal or abnormal, and if abnormal, the location of the abnormality. If there is an abnormality, the location of the abnormality can be immediately known and the correct initial setting information can be resent, which is extremely effective.
