Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a troubleshooting support device that can quickly respond to troubleshooting of equipment installed in a factory.

(Conventional technology) Recently, in order to be able to quickly respond to the recovery of equipment failures installed in factories, devices have been used to estimate the cause of failure based on the operating status of each equipment when a failure occurs. became.

The general configuration of this device is as shown in FIG.

That is, a controller 2 is connected to equipment 1 installed in a factory, and the controller 2 connects to this equipment! In addition to controlling the operation of Wi1, it also monitors the operating status of Wi1 and its abnormalities (
Detects the occurrence of a malfunction. A data file 3 is connected to the controller 2, and this data file 3 contains the equipment 1.
The operating status of the system is stored as historical data. The display section 4 displays the history data stored in the data file 3.

The conventional device configured in this manner operates as shown in the flowchart of FIG.

While the equipment 1 is operating normally, the controller 2 sequentially inputs the operating status of the equipment 1 and stores the input operating status. This storage will be filed as history data in the data file 3 (81-S3). However, when the controller 2 detects an abnormality in the equipment 1,
All the history data accumulated up to now is read from the data file 3, and the history data is displayed on the display section 4 (84-S6). The operator infers the cause of the failure based on the displayed historical data and endeavors to quickly restore the equipment. The cause of the failure is then filed and referenced later when a failure occurs through the same history.

(Problem to be Solved by the Invention) However, in the conventional devices as described above, the operator had to judge the cause based on the displayed history data, so there was a problem in that it took time to investigate the cause. . In addition, since the system was designed to function on a factory-by-factory basis, there is a problem in that data regarding the causes of failures obtained at each factory cannot be used effectively in relation to other factories. For example, even if the same failure that has already occurred in one factory occurs for the first time in another factory, the other factory must independently analyze the cause of the failure.

This invention was developed in order to eliminate the above-mentioned conventional problems, and is a failure response support system that enables each factory to effectively utilize the causes of failures determined at each factory. For the purpose of providing.

The first historical data storage means stores the operating status of equipment in the factory as historical data. The first transmitting means is
The occurrence of an abnormality in the equipment is detected, and history data related to the equipment that has caused the abnormality among the history data stored in the first history data storage means is transmitted. The first history data storage means and the first transmission means described above are provided independently for each factory. Therefore, the operating status of equipment is filed for each factory.

Further, the second history data storage means stores history data transmitted from the first transmission means provided for each factory together with past history data.

The failure cause analysis means, based on the past and received history data stored in the second history data storage means,
Analyze the cause of the failure of the equipment that caused the abnormality. Then, the second transmitting means transmits information on the cause of the failure analyzed by the failure cause analyzing means to the factory having the equipment where the abnormality occurred. The second history data storage means, failure cause analysis means, and second transmission means described above are provided in the support department. The display means installed at each factory are as follows:

(Example) Hereinafter, one example of the present invention will be described in detail based on the drawings.

FIG. 1 is a schematic configuration diagram of a failure handling support device according to the present invention. As shown in the figure, an equipment controller 5 is provided that controls the operation of the equipment 1 and detects that a failure has occurred in the equipment.

A data file 3 as a first historical data storage means is connected to the equipment controller 5.
The operation status of the equipment 1, that is, historical data is accumulated and stored via the equipment controller 5. When an abnormality in the equipment 51 is detected by the equipment controller 5, the modem 6 transmits history data stored in the data file 3, and displays received information on the cause of the failure (described later), that is, instruction information, to the display device 4. The equipment controller 5 and this modem 6 constitute a first transmitting means. Further, the display device 4 functions as a display means. In addition, the equipment controller 5. The data file 32 display device 4 and modem 6 are provided in each factory. Therefore, the historical data stored in data file 3 is unique to that factory. Here, the historical data refers to the failure history of equipment, that is, data on what kind of failures have occurred in what kind of machines.

When a failure occurs in the equipment 1 of any factory, the support department, which is the department that investigates the cause of the failure, specifically the development department, receives a message sent via the modem 6 of the factory that has the failed equipment. a modem 10 that receives historical data received by the modem 10; a data file 11 that stores the historical data received by the modem 10 together with past historical data;
an analysis simulation 12 that analyzes and simulates the cause of failure of equipment that has failed based on historical data stored in the analysis simulation 12; a data file 13 that stores information on the cause of failure obtained by the analysis simulation 12 as result data; A display device 14 that displays the result data stored in the data file 13 and information on the cause of failure obtained by the analysis simulation 12
It is equipped with The result data stored in the data file 13 is stored in the modem 10. It is displayed on the factory display device 4 via the modem 6. The modem 10 functions as a second transmission means, the data file 11 functions as a second history data storage means, and the analysis simulation 12 functions as a failure cause analysis means.

The troubleshooting support device has the above configuration, but
The specific operation of the device is as shown in the flowcharts of FIGS. 2 and 3.

The flowchart shown in FIG. 2 shows the operation of the equipment provided on the factory side, and the flowchart shown in FIG. 3 shows the operation of the equipment provided on the development department side.

The equipment installed at the factory operates as follows.

The equipment controller 5 inputs the operating status of the equipment 1, constantly monitors whether an abnormality (failure) has occurred in the equipment 1, and stores the manually input operating status in the data file 3. If no abnormality occurs in the equipment 1, the operating status is continued to be stored (S10 to 512). When an abnormality is detected by the equipment controller 5, the historical data that has been stored in the data file 3 is transmitted via the modem 6 (8
13.514). This history data will be sent to a device installed in the development department, but in the development department,
Failure analysis is performed based on this historical data, and instructions for failure recovery are output. This output instruction is input via the modem 6 and displayed on the display device 4 (S15, 51
6). The operator can repair the malfunctioning equipment in accordance with this display, allowing prompt measures to be taken.

Additionally, the equipment provided in the development department operates as follows.

When the data file 11 receives historical data sent from the data file 3 of any factory via the modem 10, the data file 11 stores the historical data (8
20,821). Next, the development department that receives this historical data simulates the operation of the equipment that caused the failure based on this historical data and investigates the cause of the failure (822.823). Once the cause of this failure has been determined,
Create result data and display it on the display device 14, and store the result data in the data file 13 (8
24.825). The result data is then transmitted to the factory display device 4 via the modem 10 and the modem 6 (
826). As a result, instruction information for failure recovery is displayed on the display device 4 of the factory that has the equipment where the failure has occurred. Incidentally, the inference of the cause of the failure performed in step S22 may be performed by performing a simulation based on past historical data while viewing the display device 14 to investigate the cause of the failure. The result data obtained as a result of this simulation is stored in the data file 14.

(Effects of the Invention) As described above, in the present invention, the factory side collects the operating status of equipment, that is, historical data, and when a failure occurs, the collected historical data is sent to the support department to analyze the cause of the failure. As a result, historical data from each factory can be shared, and since the cause of a failure is investigated by a specialized department, recovery in the event of a failure can be carried out quickly.
