Abstract

PURPOSE:To enable a maintenance man to grasp individual histories of fault items by storing the generating time, generating frequency an importance order of a fault signal in a data file and displaying these contents on a display device in accordance with designating operation. CONSTITUTION:In fault information record, a programmable controller 4 inputs the data of a fault contact 5 in equipment, detects a point generating the fault, and when the fault is a newly generated fault, counts up the generating frequency of the point in a generating frequency file by '1' and writes data and time data in a generating date file. Then, the controller 4 extracts an importance order file and updates an importance order display file in accordance with the current importance order. In the case of displaying the fault information, button data on a control panel 3 are inputted and data are extracted from a generating frequency file, a generating data file and an importance order file in accordance with the contents of a display request and displayed on a display device 2.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a failure information display device for a monitoring panel that uses a programmable controller to store failure information item by item and displays it in response to an operator's request. It is related to.

(Prior art) Conventionally, when a failure occurs in the local equipment or when controlling equipment locally, maintenance personnel go to the local equipment and install the monitoring panel on the local equipment side. It is configured so that it can be monitored and controlled.

Local equipment is always unmanned, and conventional monitoring boards are not equipped with printers or CRTs for recording failures. Therefore, even if equipment failure items can be monitored on the monitoring board, failures do not occur. The date and time and number of failures to date are unclear, making it impossible to obtain statistical data on equipment maintenance and making it difficult to prioritize responses when multiple failures occur. Therefore, there was a problem that proper maintenance and monitoring could not be carried out.

(Problems to be Solved by the Invention) An object of the present invention is to provide a failure information display device for a monitoring panel that stores the occurrence progress of failure items and displays the guidance, thereby improving the level of maintenance monitoring. It is said that

[Structure of the invention]

(Means and operations for solving the problem) In order to achieve the above object, the programmable controller first allocates a file for storing the date and time of failure occurrence and the number of occurrences for every failure item. For the newly occurring failure, the date and time of occurrence and the number of occurrences are stored.

In addition, importance ranking numbers are assigned to all failure items, and the rankings are compared between the importance ranking number of the newly occurring failure and the importance ranking number of the failures that have occurred up to now. Update and store the importance ranking.

When a maintenance worker inputs the name of a faulty item using a button on the operation panel, the number of times the faulty item has occurred and the date and time of the last occurrence are displayed.

Furthermore, even when multiple failures occur at the same time, the failure items with the highest priority are displayed on the display in sequence at the request of a maintenance worker using a button.

(Example) An embodiment of the present invention is shown in FIG.

In FIG. 1, 1 is a monitoring panel, 2 is a display that displays data, 3 is an operation panel for inputting display requests from maintenance personnel, and 4
5 is a programmable controller, and 5 is a fault contact on the equipment side.

FIG. 2 is a flowchart showing the procedure for storing failure information according to the present invention, and FIG. 3 is a flowchart showing the procedure for displaying failure information.

As shown in Fig. 2, the fault information record is performed by the programmable controller 1, which first inputs the data of the fault contact 5 of the equipment in step 11, and then detects the point where the fault has occurred using the input contact data in step 12. If a failure has occurred, it is determined in step 13 whether the failure has continued at that point until now, and if a new failure has occurred this time, the number of occurrences of the point in the occurrence count file is counted by 1 in step 14. Then, file the data at 0:06 on June 6, 2019 in the occurrence date and time file.

Next, in step 16, extract the importance ranking number file,
In step 17, a comparison of the importance rankings is made between the point where the failure has continued until now and the current failure point detected in step 13, and the importance ranking display file is updated according to the current importance ranking.

Next, when displaying failure information in response to a display request from maintenance personnel, as shown in FIG. If the request content is to display the number of failure occurrences at point n, the data for point n is retrieved from the occurrence frequency file in step 23, and if the request content is to display the occurrence date and time, the data for point n is retrieved from the occurrence date and time file in step 24. Take out and display in step z5. Also, if the request content is to display importance ranking, step 26
Extract all data from the importance ranking display file with
In step 27, the failure item names are sequentially displayed on the display 2.

This allows failure information including the history of failure occurrences to be displayed.

〔Effect of the invention〕

As explained above, according to the present invention, maintenance personnel can grasp the history of each failure item, improving equipment maintenance, and furthermore, when multiple failures occur, priority is given to failures with high importance. This makes it possible to implement monitoring and control with high maintenance effectiveness.
