The equipment state determination mechanism 13 is activated by the control mechanism 11 at regular intervals and determines whether or not the answer signal of the equipment answer information file 5 and the command signal of the command information file 6 match and match (processing step). 131). If the determination results do not match, the state of the equipment is in a transition state, an abnormal state, or a failure state, so it is next determined whether or not the equipment is in failure by using the signal of the equipment answer information file 5.
(Processing step 132). If the result of the processing step is YES, the failure status is set in the status flag of the equipment status file 15 (processing step 13a). Processing step 1
If the result of 32 is NO, the state of the equipment 1 becomes a transition state or an abnormal state, and therefore the response time is calculated and stored in the response time calculation file 13h (processing step 13
3), it is determined whether the response time-up time preset in the response time setting file 13i is associated with the calculated response time or not (process step 13
4) If the time is not over, it is determined that the equipment 1 is in the transition state, and the transition state flag of the equipment state file 15 is set (processing step 13f). If the time is over, an abnormal state is set in the state flag of the equipment state file 15 (processing step 139).

On the other hand, when the command information and the answer information match in processing step 131, the equipment response time is set in the trend data file 13j (processing step 1
35). Then, the answer signal of the equipment answer information file 5 is judged (processing step 136), and if the equipment 1 is in the OFF state as the judgment result, the manual operation information file 10
(Processing step 137), and if the compared results do not match, the equipment 1 is automatically turned off and the automatic state is set in the status flag of the equipment status file 15 (processing step 13b). As a result of the collation, if they do not match, it is determined to be in the OFF state by the manual operation, and the manual OFF state is set in the state flag of the equipment state file 15 (processing step 13).
c). Similarly, when it is determined in the processing step 136 that the equipment is in the ON state from the answer signal, the equipment 1 is automatically compared with the manual operation information file 10 (processing step 138). It is determined that the ON state has been set to the ON state, and the automatic ON state is set in the state flag of the equipment state file 15 (processing step 13d). On the other hand, if the collated result indicates that there is an operation, it is determined that the equipment 1 has been manually turned on, and the equipment state file 15
The manual ON state is set to the state flag (step 13e). Then, processing steps 139, 13a, 1
3b, 13c, 13d, 13e, that is, when the equipment 1 is determined to be in an abnormal state, a failure state, an automatic ON / OFF state, or a manual ON / OFF state, the equipment 1 is not in the transition state, so the equipment state is It comprises a processing step 13g for resetting the transition state flag of the file 15.

Next, the equipment state diagnosis mechanism 14 of the equipment state determination / diagnosis apparatus will be described.

FIG. 4 shows a processing flow of the equipment state diagnosis mechanism 14. The equipment state diagnosis mechanism 14 is the equipment state determination mechanism 1
Equipment failure diagnosis is performed using the accumulated response time data of the trend data file 13j edited in step 3 (processing step 141). In this case, for example, a certain period of time is provided and the determination is made by comparing with the response time. Then, the wear degree data is edited from the accumulated response time data (processing step 142). In this case, the response time and the degree of wear are associated in advance for each equipment, and the corresponding degree of wear is obtained from the obtained response time, or the difference between the previously obtained response time and the response time obtained this time is calculated. From the wear degree.

In this way, the equipment state determination / diagnosis device 12
Then, from the equipment answer information file 5, the command information file 6, and the manual operation information file 10, the state determination and the failure diagnosis are performed, and the equipment state information file 15 is generated.

FIG. 5 shows a processing flow of the drawing mechanism 17.

Processing step 171 for editing drawing data by using the information of the flow source picture information file 16, processing step 172 for changing the brightness of the corresponding equipment pixel by using the wear degree data of the equipment state file 15, and flicker of the equipment state file 15. Processing step 173 for determining a flag, if the determination result is flicker, processing step 174 for designating blinking of the corresponding equipment pixel, status flag of equipment status file 15, equipment answer information file 5, command information file 6, response time A processing step 1 in which the state before transition or the state after transition is determined using the calculation file 13h and the response time setting file 13i, and the corresponding equipment pixel display color is designated
75, when the determination result of processing step 173 is that there is no flicker, the equipment state is determined by the state flag of the equipment state file 15, and the corresponding equipment pixel display color is designated. If it is not completed, processing step 172 comprises processing step 177 for editing the next equipment.

Next, a specific operation in each case will be described.

First, the case where the steady state is automatically turned on will be described. This is a case where the answer data of the equipment answer information file is “ON”, the command data of the command information file is “ON”, and the manual operation data of the manual operation information file is “none”. Therefore, in the equipment state determination / diagnosis device 12, it is determined that the command data and the answer data match (processing step 131), and after the processing 135, the manual operation is determined (processing step 138). And
Since the manual operation data is "absent", the automatic ON status code is set to the status flag of the equipment status information file 15 (processing step 13d), and the equipment status information file 1
The flicker flag of No. 5 is reset (“OFF”) (processing step 13g). Further trend data file 13
A failure diagnosis is performed using the data of j (processing 141), and the equipment wear degree data of the equipment state information file 15 is set (processing 142) (the wear degree is 10 in this embodiment). In this way, the equipment state information file for the equipment A in FIG. 2 is created.

In the drawing mechanism 17, the drawing data is edited using the data of the flow source picture information file 16,
The brightness of the corresponding pixel is determined from the equipment wear degree data of the equipment state information file 15. Also, equipment status information file 1
Since the flicker flag of No. 5 is "OFF", the operating status of the corresponding equipment is displayed using the status flag information of the equipment status information file 15. The result processed in this way is displayed on the output device 19 as shown in FIG. Further, by displaying a brightness table on the output device 19 and comparing it with the brightness of the operation state display of the corresponding equipment, the operator can judge the degree of danger of the corresponding equipment. This allows
The operator can confirm the condition of the equipment on the screen.

Next, when the steady state is manually turned ON, the answer data in the equipment answer information file is "ON", the instruction data in the instruction information file is "ON", and the manual operation data in the manual operation information file is "ON". Yes, the status flag of the equipment status information file is "automatically ON", the flicker flag is "OFF", and the wear degree is "4". In this case, as shown in FIG.
Is displayed in.

When the steady state is manually turned off, when the steady state is automatically turned off, and when the steady state fails, the answer data of the equipment answer information file, the command data of the command information file, and the manual operation data of the manual operation information file are similarly used. The equipment status information file is created and displayed on the output device 19.

Next, the transition state answer waiting state will be described.

This means that the manual operation of the manual operation information file 10 is "ON" and the command data of the command information file 6 is "ON", but the answer data of the equipment answer information file 5 is "OFF". As a result, there is a state waiting for the equipment to be turned on.

In the equipment state judgment / diagnosis device 12, the answer data of the equipment answer information file 5 is "OF".
F ”, it is determined that the command data in the command information file 6 does not match“ ON ”(processing step 131), and since the answer data in the equipment answer information file 5 is not in failure, the response time is counted (processing Step 13
3) Update the response time of the response time calculation file 13h. Then, the response time of the response time calculation file 13h and the set time of the response time setting file 13i are compared (processing step 134). In the transition state, the response time is within the set time, so the equipment state information file 1
The flicker flag of 5 is set (processing step 13
f), failure diagnosis is performed using the data of the trend data file 13j (process 141), and the equipment wear degree data of the equipment state information file 15 is set (process 142).
Then, the state flag of the equipment state information file 15 remains in the state set last time.

In the drawing mechanism 17, in step 171, the drawing data is edited using the data of the flow source picture information file 16, and in step 172, the equipment state information file 1 is edited.
The brightness of the corresponding pixel is changed from the equipment wear degree data of No. 5, and the flicker flag of the equipment state information file 15 is “ON” in the determination processing 173. Therefore, the blinking of the corresponding pixel indicating the transition state is performed in processing 174. In the process 175,
Using the data of the response time calculation file 13h and the response time setting file 13i, the operation state display before the transition and the state display after the transition are alternately displayed.

The state before the transition is the equipment state information file 1
For the state flag 5 and the state after transition, the operating state is determined using the information in the command information file 6 and the manual operation information file 10. In addition, the time for alternately changing the display state is such that the state before the transition is gradually shorter and the state after the transition is gradually longer so that the direction of the transition can be known.

A display example in this case is shown in FIG. Displaying the transition state in this way is useful when the answer data of the equipment cannot be immediately obtained in response to the operator's operation input (for example, it takes time to create a control command or the next control To perform another control once,
Even if it is the response characteristic of the target equipment), the operator can see on the display screen that the operation command is normally sent to the equipment. Therefore, it is possible to prevent a situation in which the same operation is erroneously input.

If the answer from the equipment does not return after the operation command and the state change waiting time is over,
As a result of the comparison between the response time of the response time calculation file 13h and the set time of the response time setting file 13i, the set time is exceeded (processing step 134). Then, an abnormal status code is set in the status flag of the equipment status information file 15 (processing step 139). The drawing mechanism 17 performs the same processing as described above. As a result, it is displayed as shown in FIG.

When the answer from the equipment is returned, it is in the same state as the steady state manual ON described above,
Similar processing is performed. Then, the response time of the response time calculation file 13h is set in the trend data file (processing step 135), and the equipment diagnosis information is updated.
Therefore, the display content of FIG. 9 is changed to the display content of FIG.

According to the present embodiment, the operator can confirm whether the equipment is in the steady state, the transition state, the normal state, or the abnormal state by checking the display of the equipment state and whether or not it is blinking. It is possible to easily determine whether or not a failure has occurred.

[0045]

According to the present invention, the operator can easily judge the operating state of the equipment on the display screen.

Further, when the equipment is in a transition state, a blinking display is performed, and the change in the state of the equipment is indicated by changing the cycle of this blinking so that the operator can see the change in the equipment state at a glance. It can prevent erroneous operation.
