Problems solved by technology

In this method, an alarm message is issued only after the equipment operating state deteriorates to a certain value. At this time, it is often too late to intervene, which will eventually cause protective shutdown of the equipment in operation or damage to the equipment, and even cause accidents; in order to prevent this from happening, To play the role of early warning, sometimes the alarm value will be set small, which may cause a large number of false alarms, and the early warning effect will not be achieved

Embodiment 1

[0016] see image 3 , taking the operation of a certain large-scale rotating equipment as an example: when a certain equipment is running, the general vibration value is below 40um, the high alarm value is 130um, and the high-high protection shutdown value is 160um. The trend alarm is used. As long as the program judges that multiple consecutive sampling values ​​continue increase, an alarm will be issued for the deterioration of the equipment status to remind the operator to take timely intervention measures. XISA201X, XISA201Y, and XISA202X in the figure below show the shaft vibration value alarm screen of the blast furnace residual pressure power generation (TRT) unit. This screen will not be displayed on the main control screen during normal operation. When the alarm condition is reached, the screen will pop up automatically. Alert the operator. T202A in the figure is the temperature alarm screen of a certain bearing in the shaft system. Similarly, the screen will not be ...

Abstract

The invention relates to a dynamic equipment monitoring method. A PLC completes logics determination on the basis of common PLC logics and an operation interface, and the man-machine interface is provided with trend alarm and alarm signal output; a sampling period can be fixed during operation of the PLC, such as, collection is carried out every 0.1 second, one average is generated every 20 times,namely 2 second, and five averages can be generated in 10 seconds. Thus, a system emits an alarm signal if certain analog quality is increased or decreased for 10 second continuously, and warning forthe state of equipment can be much earlier.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment, and relates to a dynamic monitoring method for equipment. Background technique [0002] At present, the equipment status alarms in all industrial fields adopt the method of fixed alarm value to warn the equipment status, such as high-value alarm, high-high value shutdown, etc. In this method, an alarm message is issued only after the equipment operating state deteriorates to a certain value. At this time, it is often too late to intervene, which will eventually cause protective shutdown of the equipment in operation or equipment damage, and even cause accidents; in order to prevent this from happening, To play the role of early warning, sometimes the alarm value will be set small, which may cause a large number of false alarms, and the early warning effect will not be achieved. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior ar...
