Method for displaying multi-item alarm information at single position of operation screen

Abstract

The invention relates to a method for displaying multi-item alarm information at a single position of an operation screen. The method for displaying multi-alarm information in a single position of the operation screen comprises the following steps: using HMI system software in GE Company to organize the order of the multi-item alarm information of each device in real time according to the importance; expressing all the chains of the alarm information in a program; and manufacturing the abnormal chain information at a screen position, and selecting the display mode and content according to need. The method for displaying the multi-item alarm information at the single position of the operation screen has the advantages of wide information contents and complete scheme, ensures that an operator directly observes and knows the information contents through the frequently used screen and knows a dispelling method, saves complicated calculation process of searching the program, shortens the accident handling time, improves the equipment operation rate, and guarantees the device safety and smooth operation of the production; and the method is simple, the program is concise, the display screen is clear, and the operating method is easy to grasp.

Description

technical field [0001] The invention belongs to the field of electrical automation control, and in particular relates to a method for enabling multiple alarm information of equipment to be displayed on a single position of an operation screen of a display. Background technique [0002] At present, the information and signal alarm displays used by the HMI man-machine interface or the 0PS operation station automatically controlled by metallurgical industrial enterprises mainly include the following three types: [0003] 1. The screen jumps out of the fault alarm display; [0004] 2. Record and archive alarm display; [0005] 3. Screen signal alarm display. [0006] The above three alarm display methods have more or less certain shortcomings and limitations in actual field application: [0007] The screen pop-up fault alarm display is generally used in more serious fault alarm display. When a fault occurs, it can jump out of the main operation screen in the first time, so th...

Problems solved by technology

[0006] The above three alarm display methods have more or less certain shortcomings and limitations in actual field application:

We often find that the automatic operation conditions of some equipment are not met or the conditions are not met, and the equipment cannot operate automatically

However, these automatic operating conditions cannot be displayed in the above alarm information, so the electrical automation duty personnel have to be verbally informed to find the automatic interlocking conditions in the PLC program

Then carry out relevant analysis and troubleshooting, which is inconvenient and delays time, and sometimes even causes parking accidents, which brings great hidden dangers to equipment safety and smooth production.
