2. Description of the Related Art Conventionally, as such a man-machine device,
For example, there is a plant operating state monitoring device described in Japanese Patent Application Laid-Open No. 60-191389 or Japanese Patent Application Laid-Open No. 61-105698. FIG. 38 shows a block diagram of these devices. In the figure, reference numeral 901 denotes an electronic computer having input terminals 901a to 901n, a plurality of keyboards 902a to 902n, and a plurality of CRT displays 9
03a to 903n and display lamps 904a to 904n for displaying an alarm. As shown in FIG. 39, the structural features of the conventional invention are, as shown in FIG. 39, a correspondence table 910 in which an abnormal state and display contents are associated with each other, a measurement signal from the plant 9, and the like. The display device 911 is provided.

Next, the operation will be described. Signals from measuring instruments and the like in the plant are input terminals 901a to 901a.
n is input to the computer 901. In the electronic computer 901, the abnormality detection / display means processes the signal sent from the measuring instrument and monitors whether an abnormal state occurs in the plant. The predefined correspondence table 910 shown in FIG. 40 defines an abnormal state, an image 921, and a CRT for displaying the image. If an abnormality occurs, the CRT of the display destination and the image to be displayed are displayed from the table 910. An appropriate image is displayed on an appropriate CRT according to the type of the specified abnormality.

[0004]

As described above, in the conventional apparatus, as described above, the C to be displayed as an abnormal state by the correspondence table is used.
Although the correspondence between the RT and the image can be set with flexibility, there are the following problems. Assignment 1. Processing for an input event from the plant, such as detection of an abnormal state, and processing corresponding to an operation by an operator are implemented as logic in a program programmed in advance in the computer 901.
Therefore, in order to change this process by changing the specification, the system must be stopped and programming must be performed again, and the flexibility in changing the specification is lacking. Task 2. The drawing process for displaying the state of the plant and inputting from the screen is also performed by the computer 90.
Since it is implemented as logic in one pre-programmed program, it lacks flexibility in changing specifications. Issue 3. Unless processing is performed by associating abnormal conditions with display contents, the processing contents are implemented as programs and all functions are black-boxed as a single system. System cannot be built.

The present invention has been made to solve the above problems, and can flexibly cope with a change in the specification of a process corresponding to an input event from a plant or an operation by an operator. In addition, an object of the present invention is to be able to flexibly cope with a change in specifications in output processing such as drawing. It is another object of the present invention to reduce the development cost of the system and shorten the development period by selecting functions prepared in advance as modules and combining them so that the system can be constructed.

【Example】

Embodiment 1 FIG. FIG. 1 is an apparatus configuration diagram showing a first embodiment of the present invention. In the figure, 1 performs input / output with an operator input / output device 100 such as a CRT display 11, a touch panel 12, a keyboard 13, a speaker 14, and a microphone 15. The operator input means 2 receives an event from the plant 9 or the operator input / output means 1, outputs a command event or an operator output instruction (OP output instruction), and refers to the event input / delivery information 21 as an event input / delivery means. Is a processing task starting means for inputting a command event, outputting a starting instruction, and referring to the processing task starting information 31;
4 is a processing task executing means for inputting a start instruction, starting and executing the modularized processing task 41, and outputting its execution output as an OP output instruction, 5 inputting an OP output instruction and outputting an OP output, This is an operator output (OP output) processing unit that refers to the modularized OP output component 51.

Here, the OP output component means, in addition to using a later-described drawing component or a combination thereof, an audio component, a video or a character string (text) display, that is, a text display or the like. This is a component in which the media that is output to is modularized. For this plant monitoring, if it is a voice, an alarm or a warning voice is set as one pattern in advance as a software component, and is output according to the state of the plant. Furthermore, in addition to the sound, a warning (warning) is displayed by displaying characters (texts), and the occurrence of a fire is notified by a video or the like. That is, a drawing component and its combination component are used, and other multimedia such as audio and video, and further, a multimedia obtained by fusing them are made into components and called as needed.

Next, the operation will be described. In this embodiment, a process executed based on an output from a sensor installed in a plant will be described as an example, and a description will be given with reference to a flowchart showing a process flow shown in FIG. First, touch panel 1
2, an operator's request from an operator input / output device 100 such as a keyboard 13 and a microphone 15 is passed through the operator input / output unit 1 as an event input / delivery unit 2 as an event.
Is input to The measurement data from the plant 9 is input to the event input / delivery means 2 as an event. Here, “output data of sensor A in plant 9 is 15
It is assumed that an event "was" was input (S1).

The event input / delivery means 2 determines the output according to the input event by referring to the event input / delivery information 21 (S2). The output destination is determined according to the type of the event, and a command event is output to the processing task activation means 3 and an OP output instruction is output to the OP output processing means 5 (S4, S8). Here, it is assumed that event input delivery information as shown in FIG. 3 has been given. At this time, the processing task activation means 3 is assigned to the event "input of the value of the sensor A" as the delivery destination, and a command event "activation of the sensor determination process 1" is output as the command event (S4).

In response to the command event, the processing task activation means 4 refers to the processing task activation information 31 (S5), and transmits an activation instruction to the processing task execution means 4 (S6). The processing task executing means 4 executes the processing task according to the start instruction (S7), and the output OP output instruction is output to the OP output processing means 5 (S8).

Here, the sensor determination processing 1 is represented by a flowchart shown in FIG. Set the current value of sensor A to 15
Then, it is determined by substituting into X, and it becomes abnormal because (T
1, T2), and outputs an abnormal OP output instruction to the OP output processing means 5.
(T3). The OP processing means 5 having received the OP output instruction outputs the OP output to the operator input / output device 100 through the operator input / output means 1 using the modularized OP output component 51 if the OP output is required. Is presented to the operator (S9, S10). Also,
If there is no need for OP output, the process ends. In this example, an OP output process indicating an abnormality (for example, sounding an alarm or displaying a message indicating an abnormal state on a display screen) is executed.

Now, it is assumed that the equipment of the plant has been changed and the sensor A has been replaced with a sensor having higher sensitivity. At this time, if it was conventional, the system was stopped,
It was necessary to change the program related to the sensor A.
However, in the man-machine device according to the present invention, as shown in FIG. 5, the event input / delivery information 21 existing separately from the program is rewritten so as to be associated with the command event for starting the sensor determination process 2 corresponding to the new sensor. In the sensor determination process 2, as shown in FIG. 6, the determination reference value becomes 20, for example, if the value of the sensor A is 15, it is determined that the sensor is normal (U1, U2), and the normal OP output instruction is sent to the OP output processing means 5. It is output (U4).

As another way of holding the event input / delivery information, a parameter (P1 = 20) may be added to the command event of the sensor determination processing 10 as shown in FIG. At this time, the processing flow of the sensor determination processing 10 can set the value of the parameter P1 according to the sensor as shown in FIG. 8 and determine based on the setting (V1 to V
4).

In the event input / delivery information shown in FIGS. 3 and 5 in which such parameters are not set, all necessary processing tasks must be prepared in advance, but if they are parameterized as shown in FIG. It is only necessary to collect the prepared processing tasks as one general-purpose processing task.

In any case, as described above, the command event corresponding to the input event can be set flexibly by the event input / delivery information, and even if the specification of the system is changed, the system can be dealt with without stopping the system. be able to. The above effects can be similarly exerted for the processing task activation information, and the processing task can be dynamically changed for the same command event.

Further, according to the present invention, each function of the system can be freely selected by a combination of event input delivery information and processing task activation information. Further, since processing tasks and OP output parts are modularized, processing contents Can also be selected. Therefore, since a system can be constructed by combining these existing functions and modules, the development cost and the development period can be reduced.

As shown in FIG. 11, the screen touch operation is an operation in which the display screen changes to Y when button A on display screen X is touched, and the display screen changes to Z when button B is touched.

Since the basic flow of the process is the same as that of the first embodiment (S1 to S7 in FIG. 10 are the same as S1 to S7 in FIG. 2), a method of realizing a screen touch operation will be described here. The screen input operation is realized by the event input / delivery information shown in FIG. 12, which is delivered to the drawing processing unit 105 in response to an input event from the operator (touching button A, touching button B, etc.). Command events (displaying the display screen Y, displaying the display screen Z, etc.) are defined. The event input / delivery means 2 can refer to the event input / delivery information 21 and freely set and display a screen to be displayed by the drawing processing means 105 according to the type of touch (S11 to S13).

As described above, the event input delivery means provided with the event input delivery information and the drawing processing means can flexibly cope with a change in specifications, such as drawing processing accompanying a touch operation. That is, for example, even if the specification is changed so that the display screen Z is displayed when the button A is touched, it can be easily dealt with by rewriting the event input delivery information in FIG.

FIG. 18A is a flowchart showing the flow of processing on the plant or operator input / output means 201 side, and FIG. 18B is a flowchart showing the processing flow on the event input / delivery means 2 side. First, an event occurs on the plant or operator input / output means 201 side (Y1). Then, the event is transmitted to the queue 22 with the priority according to the event (Y2). The above flow is repeated every time an event occurs. Further, the event input / delivery means 2 checks whether or not the message (event) is stored in the priority queue 22 (Y3).
If there is no accumulation, the process waits until the message arrives. If there is accumulation, the queue is searched in order of priority (Y4), and the event is received by extracting the message (Y5). The received event is subjected to the same delivery processing as in the first embodiment by the delivery processing unit 23. The above processing is repeated.
