Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a display management method for alarms, etc., and more specifically, to a process monitoring system that uses a computer to monitor various processes such as water treatment. This invention relates to a display management method for alarm history indicating the occurrence of abnormality and recovery status of equipment, devices, etc.

(Prior art) Conventionally, in this type of process monitoring system, the operating status of equipment, devices, etc. that make up the process is constantly input into a computer via a process signal input device, and it is checked whether these functions are normal or not. In other words, if the input signal from one device is a logic rOJ, it is determined to be normal; if it is a logic "1", it is determined to be abnormal; It is determined that an abnormality has occurred when rlJ changes from logic “1” to rOJ.
When this happens, it is determined that the equipment has returned to normal condition.

Then, while storing these state changes in memory,
After converting the data into display data, it is displayed on the display screen 31 of the display device via the display control device as shown in FIG. 6, and the display items include the date and time of abnormality occurrence and It consists of the name of the failed device, etc. Furthermore, when a piece of equipment is restored to normal condition, the date and time and the fact of restoration are also displayed, allowing operators to monitor the process. At the same time, this information can also be output as a hard copy using a suitable printing device.

Furthermore, when it is desired to inquire about the alarm history of a process due to a change of operator, the above information can be read out from the memory by operating an input device such as a keyboard, and displayed or printed as an alarm history screen.

Other facts other than these, such as the measures taken for recovery and the names of those who took those measures, were generally communicated to subsequent operators verbally or in a handover diary.

(Problems to be Solved by the Invention) However, this method has the following problems when operating the monitoring system.

In other words, it is difficult and cumbersome to verbally communicate the measures for recovery and the name of the person responsible for each device that has been restored after an abnormality has occurred, or to write them down in a handover diary, etc. Another problem is that it takes a lot of time for other operators who have taken over to check these items, which puts a heavy burden on the operators.As a result, the smooth operation of the plant is hindered. there were.

The present invention was proposed in order to solve the above problems, and its purpose is to display information such as recovery measures taken in response to an abnormality in equipment, the name of the person taking the measures, etc. at the time the alarm is displayed. By inputting the countermeasure information into a computer and displaying it together with the countermeasure information at the time of redisplaying the alarm history, it is possible to speed up and ensure the handover of operators, and further improve the effectiveness of alarms, etc., which has enabled smooth operation of the plant. The purpose of the present invention is to provide a display management method.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides measures for recovery in response to an alarm when a display device displays an alarm regarding the occurrence of an abnormality in equipment, devices, etc. that constitute a process. Countermeasure information such as the contents of the countermeasure and the name of the countermeasurer is written from the countermeasure information storage memory to the equipment status storage memory by operating an input device, and then when displaying the alarm history, the countermeasure information is written along with the alarm to the equipment status storage memory. The feature is that it can be read from and displayed. Further, these display contents are printed out by a printing device as necessary.

(Operation) According to the present invention, when an abnormality occurs in a process, an alarm consisting of the date and time and abnormality items is displayed, and these data are stored in the equipment state storage memory.

At this time, if any measures are taken for recovery, countermeasure information consisting of the details of the countermeasures and the person responsible for the countermeasures is added and stored in the equipment state storage memory based on the operator's input.

Then, in response to a request to output the alarm history from another operator who has taken over, the countermeasure information is read together with the alarm from the equipment state storage memory and displayed on the same display screen.

All of the areas 38 to 3e shown in FIG. 3 correspond to one display item 12 in FIG. 2.

Next, the display management method in this embodiment will be explained in detail.

First, data from various devices, devices, etc. in process PR is input to the process signal input device fll, and the abnormality occurrence/recovery detection means 2 detects the state change of the input signal, that is, from logic "1" to rOJ or from logic "1" to "rOJ". 1", the occurrence of an abnormality or recovery to normal state is detected. Then, the date and time when these events occurred and their item names are stored in each of the areas 38 to 3C of the device state storage memory 3, respectively.

At the same time, these data are sent to the display control device 5 via the display data conversion means 4, converted into video signals, and displayed on the display device 6. This allows the operator to recognize the occurrence of an abnormality in process equipment or the like or its recovery. Furthermore, operators can use input devices as needed! By issuing a print command from 7, the printing device 9 is driven via the printing control device 8, and the same content as that displayed on the display device 6 is printed as a hard copy.

If an abnormality has occurred in a certain device and recovery measures have not yet been taken, the display screen of the display device 6 and the hard copy will display the alarm number display section 12a among the display items shown in FIG. Predetermined display output is performed only on the date and time display section 12b and the item name display section 12c, and the rest of the recovery date and time display section 12d, countermeasure content display section 12a, and measurer name display section 12f remain blank.

In this state, if an operator or countermeasure worker takes some kind of measure to recover from the occurrence of an abnormality, refer to Tables 1 and 2 below prepared in advance, and explain the details of the countermeasure and the countermeasure person. The countermeasure number and countermeasure operator number corresponding to the name are input from the input device 7.

Here, the data regarding the countermeasure content and the name of the countermeasurer is stored in advance in the countermeasure information storage memory 11, but the countermeasure number and countermeasurer number corresponding to these items are also stored in the countermeasure information storage as a table. It is preferable for input operations to be stored in the memory 11 and to be able to display the first and second tables on the display device 6 in response to commands from the input device 7.

Incidentally, it is of course possible to prepare the above-mentioned Tables 1 and 2 as documents.

When entering the countermeasure number and countermeasure number.

Following the procedure shown in FIG. 4, the operator presses the countermeasure key 13 provided on the input device 7 on the display screen 6' where the countermeasure content display section 12e and countermeasure person name display section 12f are blank. Operate to call up an input field 6'' for countermeasure numbers, etc. at the bottom of the display screen 6'.

Thereafter, the operator recognizes the number (for example, "1") for which countermeasures have been taken from the alarm number on the display screen 6'.

This alarm number is input into the input field 6'' by operating the numeric keypad 14 provided on the input device 7. At the same time.

Referring to Table 1 and Table 2, the corresponding countermeasure number (for example, "2") and countermeasure plan number (for example, "1") are input into input a6'' by operating the numeric keypad 14.

Next, when the registration key 15 provided on the input device 7 is operated, the countermeasure content corresponding to the countermeasure number "2" previously stored in the countermeasure information storage memory 11 (in the example in Table 1, "Repair requested" is displayed). ") and the name of the countermeasurer corresponding to countermeasure number "1"("Takahashi" in the example in Table 2) are read by the data reading/writing means 10, and these data are stored in the device state memory. Memory 3 countermeasure content storage area 3
d and the countermeasure content storage area 3e, respectively.

At the same time, the above-mentioned countermeasure contents and countermeasure person's name are displayed on the countermeasure contents display section 12a and countermeasure worker's name display section 12f of the display item 12A on the display screen, respectively, as shown in FIG. 5 via the display data conversion means 4. It will be done. Further, the updated display contents can also be printed by the printing device 9 in response to a print command from the input device @7.

Note that 12B in FIG. 5 is a display item related to another display example.

In this way, the display items 12A, 12B, .
For example, an alarm history can be displayed or printed out based on commands from the input device @7 by another operator who has been replaced, eliminating the need to communicate the equipment status verbally or using a handover diary when taking over. For example, from display item 12A in Figure 5, worker "Takahashi" has already requested repairs due to a failure in the No. 1 pump, but the operator after taking over informs that the repairs have not yet been completed. This makes it easy to recognize.

In this embodiment, a case has been described in which the operator additionally inputs only the details of the measure and the name of the person taking the measure as countermeasure information for recovery; however, the present invention is not limited to this.
It can also be applied to the case of additionally inputting other countermeasure information such as the estimated recovery time, the cause of the abnormality, etc.

(Effects of the Invention) As detailed above, according to the present invention, the details of recovery measures taken by operators and the name of the person taking measures are stored in response to various abnormalities in equipment etc. that occur during plant operation. At the same time, these can be recognized at a glance by requesting the output of the alarm history, which eliminates the complexity of communicating information verbally or through handover logs, etc., and greatly reduces the burden on operators. It has the effect of being reduced.

At the same time, smooth operation of the plant is possible by eliminating omissions in matters to be taken over, and in the event of the same type of abnormality occurring, quick responses can be made by referring to the alarm history and referring to past countermeasures. It has various effects such as
