Abstract

PURPOSE:To accurately recognize the time of the occurrence and restoration of a fault by storing display data when an alarm input is changed and change occurrence time data and displaying and confirming them as history data afterwards. CONSTITUTION:The display data in which the change of the state of the alarm input is detected is stored along with the data of the occurrence of the state change from a clock part 7 in a fault history data storage part 6 as new data. When there occurs such fault that is restored before a maintenance personnel can confirm it, fault history data display mode can be brought about with the operation of a display selection switch 8 and each time the switch is pressed, the fault history data and the occurrence time data of the state change can be displayed from the latest data on an alarm display part 4 and a time display part 5. Thus, the occurrence of the fault and the restoration state which are unknown can be immediately and accurately confirmed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm display panel, and more particularly to an alarm display panel that centrally displays alarm information from various devices and facilities.

[Conventional technology]

Conventionally, this type of alarm display panel has been used to intensively display alarm information using a display such as an LED.

[Problem to be solved by the invention]

The above-mentioned conventional alarm display panel simply displays alarm information centrally using a display such as an LED, and cannot recognize alarm information that has been restored before being checked by a maintenance person. There is also the problem that it is not possible to accurately recognize the time when a failure occurs or when recovery occurs.

The purpose of the present invention is to enable alarm information to be checked later even if it has been restored before being checked by a maintenance person, and to be able to accurately recognize the time when a failure has occurred or when it has been restored. Our goal is to provide display panels.

[Means to solve the problem]

The alarm display panel of the present invention includes: (A) an information input section into which alarm information is input; (B) a state change detection section that detects a change in data of the input alarm information; (C) data of the alarm information. (D) a time display section that displays the current time and the historical data occurrence time; (E) storing change data of the alarm information detected by the state change detection section together with change occurrence time data; a fault history data storage unit, (F) displaying display data indicating the occurrence status of the current alarm information and the time of occurrence, or displaying change data and change occurrence time data of the alarm information stored in the fault history data storage unit; (G') a clock section that generates the time data; and (G') a clock section that generates the time data.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 11 is a block diagram of an embodiment of the present invention.

The alarm display panel shown in FIG. 1 includes an information input section into which alarm information is input, a state change detection section 2 which detects changes in data of the input alarm information, and an alarm display section 4 which displays data on the alarm information. , a time display unit 5 that displays the current time and history data occurrence time, a fault history data storage unit 6 that stores change data of alarm information detected by the state change detection unit 2 together with change occurrence time data, and a fault history data storage unit 6 that stores the change data of the alarm information detected by the state change detection unit 2, A display control unit 3 that performs display selection control for displaying display data indicating the occurrence situation and occurrence time, or displaying change data of alarm information stored in the failure history data storage unit 6 and change occurrence time data. , a clock section 7 that generates time data.

Next, the operation will be explained.

In Fig. 1, newly generated alarm information is input to the information input section 1.
When the data is input to , the data is sent to the state change detection section 2 and compared with the previous display data, and it is detected that there is a state change. The data for which a state change has been detected is stored in the fault history data storage section 6 as new data together with the state change occurrence time data from the clock section 7. Furthermore, the data sent from the information input section 1 to the state change detection section 2 is also sent as is to the display control section 3, and is displayed on the alarm display section 4 as current data. The time display section 5 then displays the current time based on the time data from the clock section 7.

If there is a fault that has been resolved before the maintenance personnel can check it, operating the display selection switch 8 will switch to the fault history data display mode, and each time you press the switch, the latest fault history data will be displayed sequentially. Since it is displayed on the alarm display section 4 and the time display section 5 together with the occurrence time data, the occurrence of an unconfirmed fault and the recovery status can be immediately confirmed. Note that the display selection switch 8 may include a reset switch for switching from failure history data display mode to normal display mode, a switch for reversing the display order of history data, and the like.

〔Effect of the invention〕

As explained above, the present invention stores the display data when the alarm input changes and the change occurrence time data, and later displays and confirms them as historical data, thereby allowing maintenance personnel to This has the effect that even alarm information that has been restored can be checked later, and that the time when a failure occurs and when it is restored can be accurately recognized.
