Abstract

PURPOSE:To attain the effective supporting to a worker who executes the work to recover a defect while a defective place is investigated by detaching plural portable computes to a linking device connected to a telephone line and providing a function to be ale to support in parallel to plural defect investigating recovering works at a central computer. CONSTITUTION:By a knowledge input device 1 before the defect occurs, the knowledge of an expert engaged in a defect investigating recovering work is inputted to a data file 201 of a central computer 2. When the defect occurs, a worker 12 connects a portable computer 3 to a linking device 5 in the vicinity of defect facilities 13 and links it through a telephone line 4 with the central computer 2. Since an arithmetic unit 208 outputs the facility name of the factory to the CRT picture of the portable computer 3 by a selected factory name and the data file 201, the worker 12 inputs the name of the facility where the defect occurs. In the same way, the type of the defect condition of the facility selected successively in accordance with the input of the worker 12 and the defect condition name for the type of the defect condition are outputted by the arithmetic unit 208.

By presenting the necessary information such as appropriate work procedures to the work t1 based on the results of the repair side regarding the equipment, it is possible to easily and quickly perform the investigation and recovery work even if the work is unfamiliar to you. This invention relates to an investigation and recovery work support device.

[Prior art] Examples of devices that support equipment failure investigation and recovery work include (1) [Electrical equipment w4 in steel plants].

If the result is outside the allowable range, it is diagnosed as an abnormality, so it is possible to diagnose abuse or failure conditions that are subject to diagnosis.
& kind was extremely limited. Furthermore, it is not possible to display work procedures, equipment flow diagrams, and equipment layout diagrams as necessary, and failure investigation and recovery work cannot be facilitated.

(2) is an example of a countermeasure device for a fixed CRT, and when investigating devices in a large factory or scattered over a wide area, it is impractical to use it while inspecting near each device. Met. This is because installing a fixed CRT on the machine side of the device would be extremely expensive. In addition, this device can only input data related to the causal relationship between the failure situation and the cause of the failure expressed in conditional statements, and data related to the cause of failure and recovery method expressed in the conditional statements, and is useful for failure investigation and recovery work. It has not always been easy to input knowledge related to In addition, since it was not possible to display equipment flow diagrams and equipment layouts [4] as needed, it was necessary to provide support for unfamiliar work 0.

In order to solve these problems, we will conduct work to restore the failure while investigating the defective parts of the equipment in the vicinity of large-scale equipment or equipment scattered over a wide area. The purpose is to provide a practical "failure investigation and recovery work support device" that provides support.

In order to perform failure investigation and recovery work using this device, first, before a failure occurs, use the "knowledge input device l" shown in Figure 2.

As explained above, data files 202 to 207 are created for each piece of equipment in each factory. Then, as an example, when the knowledge necessary for the above-mentioned failure investigation and recovery work is acquired by each file, the support for the failure investigation and recovery work is almost complete.

When a failure occurs, as shown in Figure 2, ``Worker 12J who performs failure investigation and recovery work connects ``Portable Computer 3'' to ``Coupler 5'' near the failure equipment 13.
It is connected to the "central computer 2" through the "telephone line 4".

``Central calculation fi2J first starts with the ``computer 208'' or the data file 20 in which the ``factory name, equipment name, type of failure status, and failure status name for each type'' has already been input.

The ``rA calculator 208'' outputs the factory equipment name on the CRT screen of the ``portable computer 3'' using the selected factory name and the ``data file 201''.
2, enter the name of the equipment where the failure occurred. Thereafter, in the same way, the "computer 208" sequentially outputs "the type of failure situation of the selected equipment" and the "failure situation name for each type of failure situation" in response to the input from the worker [2. Work Q12 selects at least one type of failure situation based on the visual inspection result of the failure equipment, the details of the failure of the equipment notified from the control room, etc., and further selects at least one failure situation name for each failure situation.

The "computer 208" outputs the equipment name and one or more failure status names input in this way to the "computer 209" 236
do. Below [Computer machine 209, 210, 211, 212J
Then, the data files 202 to 207 corresponding to the selected equipment name are selected and the calculation is performed.

In calculation = 209 of "Central computer 2", one or more important failure situation names are generated using the output signal 236 of the calculation unit 208 and the already input "data file 202 related to the causal relationship between multiple failure situations". Select and output 237 to the CRT screen of the portable computer 3 and calculation: 210.

Next, the arithmetic unit 210 outputs the output signal 237 of the arithmetic unit 209.
Then, select the name of the equipment to be investigated or the investigation item 1-1 based on the already input "data file 203 related to the relationship between the failure situation and the equipment to be investigated 21", and select the name of the equipment to be investigated or the investigation item 1-1 with the highest priority. The survey items are output 238 to the CRT screen of the beautiful computer 3 and to the calculation S 211.

Here, the worker 12 can also change the priority order from the portable computer 3 according to the failure status of the equipment by looking at the name of the equipment to be investigated or the investigation item [1] output from the computing unit 210.

Next, the output signal 238 of the arithmetic unit 211 and the input “
One flow or one conditional statement corresponding to the name of the equipment to be investigated or the investigation item is selected from the data file 204 related to the failure investigation and recovery method for each equipment to be investigated, and
Output 239 to 12.

Next, the computing unit 212 displays the investigation or work items on the CRT screen of the "portable computer 3" based on the output 239 of the computing unit 211 and instructions from the worker 12. The work here is "Data file 204 related to the failure investigation and recovery method for each equipment to be investigated" according to the required yellow.
It is also possible to call comments such as the method of investigation, reason for investigation, etc. from the "comment data file 205" attached to the ``comment data file 205'' and display them on the CRT screen. Based on the information listed above, the work will be carried out at the site by investigation or work, and the results will be input into the "Vorkful Computer 3".

Furthermore, the computing unit 212 determines the next direction to proceed based on the input investigation or work 2'' result and the corresponding flow or conditional statement.There are five types of directions to proceed, and l is The investigation and recovery of the failure situation has been completed, and the computer 2
09, if all the selected failure conditions have been investigated,
The process proceeds to ``End 213'' (230). Second, if the investigation and recovery of the failure situation has been completed, or if the failure situation selected by the calculation unit 209 is uninvestigated, R is sent to the calculation unit 209 (
233), repeating the same work, part 3 is determining a new investigation or work item and
” is displayed on the CRT screen. Part 4 returns to the computing unit 210 (234). First, select the name of the equipment or investigation device 11I (No. 41'4 is the amplifier power panel) shown in Figure 4 and perform the same operation. (No. 61.2161※※
). Part 5 is a new research target, a missing name or work item 7 [1 (
61'461*) and returns to the arithmetic unit 211 (23
5) It is something.

In addition, some of the flows or conditional statements of the "data file 204 related to the failure investigation and recovery method for each equipment to be investigated" require the use of the "data file 206 related to the circuit or flow of the equipment", and this flow Or, if a conditional statement is selected, the computing unit 212 automatically calls up the necessary data in the "data file 206 related to the circuit or flow of the equipment" and determines the item to be investigated or worked on.

Figure 8 shows an example of this.If the output of a certain circuit is abnormal even though all inputs are normal, that circuit is defective, and furthermore, the input and output of circuits of lower level concepts are abnormal. With a common sense and simple investigation flow that requires investigation of
It can be used to assist in failure investigation and recovery work that involves going into the details of equipment, and is especially useful when the failure investigator has experience with failures and cannot acquire sufficient knowledge related to failure investigation and recovery work. It is.

In addition, in the 2nd UA, for the computing units 209, 210, and 212, the operator calls ``Equipment layout diagram and equipment flow diagram data file 207'' as necessary.
It can be displayed on the CRT screen of Portable Computer 3.

In addition, the "coupler 5" has the calling function of a normal telephone, and by using this function as necessary, the operation can be improved.
X: The person can also obtain information on the status of equipment at a location far from the location, which is effective in speeding up failure investigation and recovery work.

It is also conceivable to input knowledge from the "portable computer 3" to the "portable computer 3" described above from the "knowledge input device 1".

However, in order to minimize the mechanical moat of [Portable Computer 3], make it lighter, and make it easier to carry,
``Portable Computer 3'' and ``Knowledge Input Device Ml
” should be kept separate. On the other hand, the "Knowledge Input Device 1" is equipped with the functions of the "Portable Computer 3", and in addition to the "Portable Computer 3", the "Knowledge Input Device, ff1lJ" is also used as a device for performing work t1 or dialogue when a failure occurs. It is conceivable to do °1.

1-The central computing a2J described above may be divided into several units, and they may be made to exchange information with each other through a subject line or a dedicated line, so that they work as if they were one computer.

If failure occurs at multiple locations simultaneously, multiple units 20 will each be

ime Sharing System)fifffi
It is capable of simultaneously processing signals related to these multiple failure investigation and recovery operations in parallel in a time-sharing manner, thereby supporting multiple failure investigation and recovery operations in parallel. Furthermore, instead of using the above-mentioned telephone line 4, it is also a good idea to use an I communication line, which costs a lot of equipment.

[Example of unfinished use] Book 9. As a concrete example, an example of support for failure investigation and recovery work for a single cylinder of thyristor Leonard equipment will be described.

The mill equipment tripped in the cold rolling factory, and the control panel of the mill equipment suffered a serious failure, ``Si risk gate cut off'' and a serious failure ``5''.
4 (breaker) trip” was displayed.

When the worker was informed of this malfunction, he rushed to the equipment in question, carrying a "portable computer" with him, installed the "portable computer" nearby, and connected it to a coupler that also functioned as a subject machine. We have begun inputting information into a ``portable computer'' for investigation and recovery work.

Figure 7 is a portion of the CRT screen resulting from the interaction between the central 1X machine and the portable computer. The ``portable computer'' is shown at 71 in the figure, as if it were one year old, it first inquires about the malfunctioning station and then goes out and cold-rolls it (3). Similarly, [Mill equipment (4 out of 72)
), input the serious fault (1) at 73 in the figure, and input "Cut off (1) J and r54 (g disconnection) trip (14) to the thyristor element" at 74 in the figure.

Here, the "central computer" selects only the serious fault "thyristor gate cutoff" from among the nif failure situations based on this input and the already stored data of FIG.

Next, the "central computer" searches for the data shown in FIG. 4 regarding the "thyristor gate cutoff" selected in section L, and selects the "thyristor power panel" as the equipment to be investigated with the highest priority.

Furthermore, the ``central computer'' searches for the data shown in Figure 6 (a) regarding the ``thyristor power supply panel J'', displays the investigation or work items on the CR7 screen of the ``portable computer'' based on that data, and then performs the work. Personnel enter the results of their investigation or work. In this way, the failure investigation and recovery work will proceed in the λ1 episode format.

In the figure, 75 to 77 show display examples and input examples by the worker, and then input normal (1) in response to inquiry 75 about whether there is an abnormality in the output of the voltage control "a @ calculation cart," and then Inquiry 76 as to whether there is any abnormality in the output of the gate pulse generator.
Normal (1) was entered for the item.

Next, in response to inquiry 77 as to whether the thyristor is normal or not, 1
After calling the comment screen 78, I investigated the thyristor and found a defective part by referring to the "diagnosis method for thyristor elements" written on this comment screen. In the work f1, when the user selects the end of the comment screen 78, the CRT screen returns to 77, so the thyristor function (2) is selected here. In this case, after this, the investigation and restoration were carried out briefly, and the final "operation preparation work 61*" in the flow shown in FIG. 6(a) was reached. Here, the "central computer" further searches for data related to "operation preparation work" from among the data corresponding to Figure 6, displays 79 in the figure, and as a result, operation is possible iE (1) What's going on? , the results shown at 80 in the figure were displayed and the work was completed.

[Effects of the Invention] As described in the following two theories, the failure investigation and recovery work support device of the present invention v1 can perform various failure investigation and recovery operations of various devices scattered within a large-scale factory or in a wide area. For work, I connected a portable computer to a coupler near the broken equipment, an unfamiliar task 11-l) On my own,
Failure investigation and recovery work can be carried out easily and quickly.
It's seven. If cargo were to arrive, it would be necessary to install an expensive fixed calculator on the machine side of all Ja machines, or to import all information online to a central computer, which was extremely expensive and impractical. , Book 9. According to Akira, instead of a large number of fixed calculators, only a small number of portable computers could be used for a small number of workers.

Furthermore, the cost of a coupler installed near the site is very small, and there are many cases where telephones with L:E configuration can be used as they are. Furthermore, existing telephone lines can be used, in which case there is no need to install new wiring. Is it therefore cheaper? It is practical because it can constitute Ca. In addition, by using the 1st floor talk function of the bonding temperature, it is possible to simultaneously receive information such as the condition of the equipment at the location where the fault occurred from the worker. According to the failure investigation/recovery Il1 work support device of the invention,
It is extremely easy to input the knowledge necessary for fault investigation and recovery work without limiting the kJ quadrangle and fault range. In particular, the effect of being able to input data related to failure investigation and restoration work methods for each equipment to be investigated in the flow format [4] on the CRT screen is remarkable.

Also, this knowledge includes knowledge of equipment circuit diagrams, and I was able to support detailed equipment failure investigation and restoration work. More +i? 81' in term i
As shown in example A, there is no prior experience of failures,
Even for failure situations where sufficient knowledge related to failure investigation and restoration work cannot be obtained, it is very effective by inputting only data related to the detailed investigation flow and equipment circuits.
! & Support for disability investigation and recovery works will be 11 to 17.

In addition, h, which is in conjunction with the central computer, increases the knowledge related to failure investigation and recovery work, increases the memory capacity needs due to the increase in equipment layerer 1 - Figure 7, and increases the speed of calculation. In addition, record and analyze the history of failure investigation and recovery work, expand opportunities such as modifying the knowledge of work X, and input it to the central computer. It has the effect that the machine rE can be easily expanded by incorporating information other than the information provided, for example, equipment information T from a process computer. In the case of the thyristor gate blocker 8 failure in the example, the investigation and restoration were carried out by experienced workers using the conventional method, and it was found that it took 9 hours to operate the device of the present invention and was not used to it. As a result, we were able to recover in about 5 hours, and the 1st LA was significantly reduced.
