Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a maintenance management system, and in particular, an equipment failure detection and stop method suitable for stopping state change detection only for equipment related to specified information. Regarding.

[Background of the invention]

If a conventional maintenance management system does not have a device failure detection/stop function, when performing nighttime maintenance work, failures will occur one after another in the equipment being worked on, making it difficult to distinguish them from actual failures that occurred during this time. In addition, the failure history displayed on the printer may not be able to be distinguished from an actual failure, or to avoid this, the equipment failure detection function may be completely stopped, making it impossible to monitor the status of the equipment during work. There was a problem with it disappearing.

[Purpose of the invention]

An object of the present invention is to cause a control processing device to store items that cause failures and devices related to them, and to stop detection of device failure occurrence and recovery only for devices related to items specified from a terminal in advance. The purpose of the present invention is to provide a method for detecting and stopping equipment failure.

[Summary of the invention]

The main point of the present invention is that when performing maintenance work, the control processing device (L
CP) is a central control unit (CCU) and station control unit (
When there is a change in the device information from the LCU, it is checked whether the corresponding device is related to the specified item, and if it is, the process up to terminal display is not performed.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

FIG. 1 shows the configuration of the operation management system in which the maintenance management system monitors the status. The operation management system consists of a CCU1 that manages the entire system, an LCU 2 that controls processes, and a maintenance management system 3 that monitors the system machines and equipment as a whole.

Figure 2 shows the hardware configuration of the maintenance management system.

Transmission control unit [4] that sends and receives data to and from the CCU and LCU; LCP5 that detects equipment failure; It consists of a CRT 8 with a keyboard and a printer 9 that prints failure and operation history.

The specific method of the failure detection and stop function is shown below.

If a failure is expected to occur during nighttime work, etc., and the dispatcher determines that he would like to perform a failure detection stop, he inputs the following data from the CRT 8 with a keyboard.

(1) Detection designated item 2 For inputting designated items, assign a number to each item and enter this number.

[Example] Motor power running = 01 ATC related 202nd class (2) Designated location: Code all central and each station,
Enter the code.

(3) Enter the specified time period 1 and the time period as follows: Stop detection.

What hour and minute to what hour and minute (hour = O to 232 minutes = O to 59) When the data in (1) to (3) above is taken into EXP'6, EXP6 transfers the operation history data to printer 9. Output and print. Also, data (1) to (3) are transmitted to LP01. When this data is taken in by LP01, a status table (hereinafter referred to as 5TAT) on the RAM area shown in FIG. 3 is created.

5TAT, specified item 11. Designated location 12. Start time 1
3. End time 14 is normally zero, but when data is imported, specified item 11. Regarding designated location 12,
The bit position of the corresponding code is ON (“i”)
do. Further, after the 5TAT is created by inputting the input data as they are for the start time and end time, a failure detection stop is performed by the linkage of the program shown in FIG. The time detection program 17 is activated by a timer at regular intervals and monitors whether the current time matches the start time 13 degrees and the end time 14 degrees. When the start time is 13, 7-7g 10 is specified for 5TAT.
woON (“1”) L, when the end time is 14,
The specifying flag 1o is set to 0FF (“0”).

The data input program 15 inputs data into the data input table 20 each time a station transmits the data.

The state change detection program 16 uses the data input table 2
0 data is imported and compared with the previously imported data for the corresponding station to check for changes in status.

FIG. 5 shows a flowchart when a state change occurs. The state change detection program first checks whether the failure detection is stopped or not by checking the specifying flag 10 of 5TAT19.
N ("1"')] indicates whether the location (station) where the device data was sent is currently specified.5TAT
19 specified location The bit status of the corresponding station in 12 (l or 0
) to check. If the bit state is It 1
'1, that is, if it is specified, it is further checked whether the corresponding device is related to the specified item 11.

The method is shown in FIG. The position file 22 has in advance a pattern indicating whether each device is related or not in the same format as the specification item 11 of the 5TAT 19.

For example, if the applicable device is associated only with code 01 of specification item 11, the pattern will be $80,00,00 in hexadecimal. This pattern and the specified item of 5TAT19 are ANDed (logical product) one byte at a time, and if all of them are zero, there is no relation, and if any one bit is -1, it is considered that there is a relation. If there is a relationship, the process is terminated; if there is no relationship, the data is registered in the state change detection table 21, the failure analysis program 18 is activated, and alarm output and printer print processing are performed.

According to this embodiment, failure detection can be stopped for specified stations and specified items.

In addition, as a second example, the finger of 5TAT19
The effect will be even more □ if you set item 11 for each location.

(Effects of the Invention) According to the present invention, it is possible to perform failure detection and shutdown for any item, any place, and any time period, and maintenance is significantly improved.

Specifically, when an actual failure occurs during work, there is no need to determine whether it is a simulated failure, unlike when this function is not available. Therefore, troubleshooting becomes easy.
