Abstract

PURPOSE:To automatically correct the message output speed in real time by storing an action corresponding to a group of messages and comparing this stored action and an action inputted by an operator with each other to correct the output speed of the group of messages. CONSTITUTION:An outputted group of messages and an operator's action corresponding to such a group are stored in a group of messages action storage part 31. An action comparing part 32 compares a state signal 6a of the action from a group of messages output control part 16 and an operation action signal 14a with each other and decides whether the operator has performed an effective action or not to output discrimination information. An output speed correcting signal determining part 33 determines an output speed correcting signal 13a of the group of messages based on decision information. Thus, the message output speed is automatically corrected in real time.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an adaptive message output control method, particularly for monitoring the status of large-scale systems such as chemical plants, electric power systems, communication systems, transportation systems, etc. The present invention relates to an adaptive message output control method that outputs a message indicating the status of the system to an operator performing a control action.

[Conventional technology]

Conventionally, a message output control method monitors the operating status of large-scale systems such as chemical plants, electric power systems, communication systems, and transportation systems, and outputs the system status as a message to the operator who takes actions to control the system. In this case, the output speed of a message is determined depending on the output speed of the physical characteristics of the output device (for example, a display or a printer) that outputs the message.

[Problem to be solved by the invention]

Incidentally, when designing a system, it is considered to be a principle of system design that messages should be output to the operator as quickly as possible. For this reason5, as the speed of output devices has increased in recent years, it has become possible to output messages at high speed, and when an output device capable of high-speed output is incorporated into a system, it is possible to output messages in a few seconds during steady operation of the system. The output that was being output at an output speed of
In the event of a failure, the number 1. O messages/minute will be output, and a large number of messages will be output from the system at approximately the same time. Therefore, high-speed message output exceeds the message identification processing ability of a human operator, and there is a risk that a necessary message may be missed. This has led to problems such as misjudgment of the cause of the failure and an increase in repair time.

For this reason, it is desirable to store in advance a message output speed suitable for the recognition ability of the operator in accordance with the content of the message to be output, and to make the message output speed variable.

The speed of the operator's actions varies, and in this case, unless the operator's actions in response to the message can be quickly fed back, there is a drawback that the message output speed cannot be adjusted in real time to adapt to the operator's recognition ability. The present invention has been made to solve the above problems.

An object of the present invention is to provide an adaptive message output control method that outputs messages at an appropriate output speed even in a system incorporating an output device whose message output speed takes into account the recognition ability of an operator. There is a particular thing.

Another object of the present invention is to provide an adaptive message output control system that can vary the message output speed in response to an operator's actions and can adapt the message output speed to the operator's message recognition ability. be.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[Means to solve the problem]

In order to achieve the above object, the present invention varies the message output speed based on the system status signal,
In a message output control method that outputs a message indicating a state of the system, an action storage means stores an action corresponding to a message group, and an action stored in the action storage means is compared with an action input from an operator. , and a correction means for correcting the output speed of the message group.

[Effect]

According to the means, in the message output control method that outputs a message indicating the state of the system by varying the message output speed based on the system state signal,
Action storage means for storing actions and correction means for modifying output speed are provided. The action storage means is executed by an operator corresponding to the output of n messages (hereinafter, the n messages are referred to as a message group) corresponding to n (n≧1) status signals transmitted from the system. Memorize the actions you should take. Further, the modifying means compares the action stored in the action storage means with the action input by the operator, and modifies the output speed of the message group to be output thereafter.

As a result, for the actions performed by the operator,
The message output speed can be modified in real time and the message output speed can be made variable. This makes it possible to automatically adjust the message output speed in real time to suit the operator's message recognition ability, and in the event of a large-scale system failure, the operator can fully grasp the system's messages. , it is possible to quickly detect and repair malfunctions.

The message output speed information f, (1≦1nk) is a value determined based on, for example, the appearance frequency of messages output by the system in the past, the time index required for the operator to recognize each message, and the like.

Among the n state signals of the state signal 10a, S is wL(

As shown in the figure, for example, for a message group of state signal transitions such as si→s2→sk, the action is aX, and for a message group of state signal transitions of sk→Sk, action is a.

This indicates that the operator needs to perform the action →a1. If, for the output of the message group of the state signal transition Syo→S□→sk.

When the operator performs the action a.

For example, the action comparison unit 32 compares a, l and a and outputs determination information that the actions are different, and the output speed correction signal determination unit 33 outputs an output speed correction signal 13a that lowers the output speed of the message group. Output.

As a result, the output speed when outputting a message group is revised downward.

The example of the function in FIG. 9 describes an example of downward correction of the output speed of a message group when, for example, the output speed correction signal 13aa is input to the message group output speed calculation unit 23.

Next, an example of operation will be explained. Before this explanation, we will state some prerequisites for this example.

(1) The status signal 10a transmitted from the system 10 is
Assume that there are three status signals of S, I, and Sla as shown in FIG. 4, and they are generated in the order of S, s2, and sk.

(2) It is assumed that the message storage unit 15 stores messages of the type corresponding to the status signals of the type shown in FIG.

(3) As shown in FIG. 6, the message output speed storage unit 21 stores message output speed information f, which indicates the appearance frequency (probability) of each type of message corresponding to each status signal.
Assume that the data is stored as Lm f3y..., fk.

(4) The message group output speed index calculation unit 22 calculates the message group output speed product #AF by calculating the average of fL (1≦i≦k) shown in the above-mentioned equation [1].

(5) The message group output speed calculation unit 23 calculates the message group output speed from the message group output speed product @F using a function as shown in FIG.

(6) In response to the output of the message group corresponding to the status signal s11 sat sk, the operator inputs an action a into the operator action input section 14.

(7) As shown in FIG. 8, it is assumed that the message group action storage section 31 stores transitions of status signals (transitions of message generation) and actions to be taken by the operator.

(8) In the action comparison unit 32, the operator action signal 14a and the action state signal 16a corresponding to the message group information in the message group action storage unit 31
and the action, and output determination result information as to whether the action is r different J or the same - J.

(9) The output speed correction signal determination unit 33 generates an output speed correction signal “r−Δ” when the judgment result information indicates that the action is “r different”, and the message group output speed calculation unit 23 generates an output speed correction signal “r−Δ” as shown in FIG. The function shown in FIG. 9 shall be revised downward as shown in FIG.

An example of operation will be explained based on the above preconditions.

First, the status signal storage unit 11 temporarily stores the three status signals 10a called S□#8295 transmitted from the system 10, and then stores the message output rate of the message group output rate determination unit 12 as the status signal 11a. It is transmitted to the storage unit 21. In the message output speed storage section 21,
Corresponding to each input status signal 31+"m18k, each message output speed information f(=0.5
0), f, (=0.15), f, (=0.15
) is selected and transmitted to the message group output speed index calculating section 22. The message group output speed index calculation unit 22 calculates these information f(=0.50), f(=0.15
).

From the value of fk (=0.15), the message group output speed index F of equation [1] is calculated and F=0.27 is output.

Next, the message group output speed calculation unit 23 calculates the message group output speed 15 (message 7 minutes) using a function from the message group output speed index value F=0.27, and controls the message group output as an output speed signal 12a. 16. The message group output control unit 16 outputs the status signal S□ as the message group information 16a.

"at S," is sent to the action comparison section 32 of the pressure speed correction section 13, and a message corresponding to the status signal SKI Sk in the message storage section 15 is generated, and the message is sent at the output speed of the output speed signal 12a. is sent to the message group output unit 17. The message group output unit 17 receives this and outputs the message shown below at an output speed of 15 (message 7 minutes).

r ABC123 ABC456789 XYZ J Correspondingly, the operator inputs the action a into the operator action input section 14.

a, the action becomes operator action signal 14a
It is sent to the action comparison unit 32 as a. The action comparison unit 32 compares the message group information 1 that has already been sent.
The message group action storage unit 31 is searched from the contents of 6a, and the expected action a is received and compared with 81 of the operator action signal 14a. As a result of the comparison,
The determination result information of "different" is transmitted as an output to the output speed correction signal determining section 33. Output speed correction signal determining section 3
3, in response to this, the output speed correction signal 13aa is
-Δ'' is generated and output to the message group output speed calculating section 23 of the message group output speed determining section 12, and the function is modified as shown in FIG.

Next, a modification of this embodiment will be explained. In the above embodiment description, the status signal 1 transmitted from the system 10
0a is the state signal S□t sa as shown in FIG.
There are three status signals called t sh, and S engineering → s2 → sk
However, the types and number of status signals are arbitrary.

Although it is assumed that the message storage unit 15 stores messages of various types corresponding to the various types of status signals shown in FIG. 5, the contents of the messages may be arbitrary.

As shown in FIG. 6, the message output speed storage unit 21 stores message output speed information f11 corresponding to the appearance frequency (probability) of the type of message corresponding to the status signal.
Although it is assumed that fm+f31...lfk is stored as the output speed information, it may be an index of the time required for the operator to recognize each message instead of the frequency of appearance.

The message group output speed index calculation unit 22 calculates the message group output speed index F by calculating the average of fL (1≦i≦k) shown in equation [1]. For example, the function F for calculating the minimum value It may be an arbitrary function such as =min (f, ,its(1s''+k)), or the value of F may be directly determined using a table of functions.

The message group output speed calculation unit 23 calculates the message group output speed from the message group output speed index F using the function shown in FIG. It may also be determined using a table of functions etc.

In response to the output of the message group corresponding to the status signal S It may also be the case that engineering I a1 → all aX.

As shown in FIG. 8, it is assumed that the message group action storage unit 31 stores the transition of status signals (transition of message generation) and the actions to be taken by the operator. As shown, expected actions for each state signal may be stored individually, or a plurality of expected actions may be stored corresponding to one or a series of state signals, or Any storage method may be used, such as selecting state No. 44 using a conditional statement instead of using a table format to find the expected action.

The action comparison unit 32 compares the operator action signal 14a and the action state signal 16a corresponding to the message group information in the message group action storage unit 31 with the action to determine whether the action is “different J” or “same −J”. Although the result information is output, instead of choosing between the two, an index of the proximity between the expected action in the message group action storage unit 31 and the operator action signal is determined, and the result information is used as the judgment result information. But that's fine.

The output speed correction signal determination unit 33 determines that when the resultant determination result information is "different j," the output speed correction signal 13a is r-.
Δ” and the seventh message group output speed calculation unit 23
The function shown in the figure is corrected downward as shown in FIG.
It may be modified upward as shown in the figure. Alternatively, as described above, a method of outputting the output speed correction signal 13a according to the proximity index may be used. Furthermore, instead of correcting the entire function downward or upward as shown in FIGS. 9 and 11, the output speed correction signal 13aa is generated together with the message group output speed product 1IIF corresponding to the corresponding message group. Only the message group output speed index F may be modified. The message group speed index calculation section 2 also sends an output speed correction signal 13ac to the message group output speed index calculation section 22 to change the weight of the average calculation.
2 may be changed, and the value of the message output speed information in the message output speed storage section 21 may be changed using the output speed correction signal 13ab.

In this embodiment, an example of modifying the output speed of a plurality of message groups has been described, but the output speed may also be modified for each message by setting n=1. Further, the time required to generate n status signals is arbitrary, and conversely, the number of status signals generated within a certain time may be set to n.

The present invention has been specifically described above based on examples, but 1.
It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof.

〔Effect of the invention〕

As described above, according to the present invention, the action to be taken by the operator corresponding to the output of the message group corresponding to the n status signals transmitted from the system is stored in the action storage means. The action stored in the action storage means is compared with the action input by the operator, and the output speed of the message group to be output thereafter is corrected, so that the message output speed can be corrected in real time in response to the operator's action. becomes possible. In addition, since the message output speed can be made variable, it is possible to automatically adjust the message output speed in real time to suit the operator's message recognition ability, making it possible to prevent large-scale system failures. In such cases, the operator can fully grasp the system's messages,
It has the advantage of being able to quickly find a failure location and perform repairs.
