Continuous casting electro-hydraulic servo system signal acquisition and monitoring system and signal acquisition and monitoring method

Abstract

The present invention provides a continuous casting electro hydraulic servo system signal acquisition monitoring system and a signal acquisition monitoring method. Each electro hydraulic servo device is connected and provided with a signal acquisition monitoring system which is configured to collect data of the electro hydraulic servo device, and the signal acquisition monitoring system is connected with an industrial Ethernet which is provided with a data acquisition module and a diagnosis monitoring module and transmits the obtained signal data to the data acquisition module and the diagnosis monitoring module through the industrial Ethernet and then transmits the signal data to a following electro hydraulic servo control system. The continuous casting electro hydraulic servo system signal acquisition monitoring system and the signal acquisition monitoring method can collect signal states of a plurality of electro hydraulic servo systems in high speed at the same time, can improve long-term data record storage, trend analysis and automatic alarm diagnosis functions, improve the data acquisition speed and access efficiency, improve the validity and speedability of fault diagnosis of a continuous casting electro hydraulic servo system, reduce the probability of faults failing to report and decrease the down time caused by faults of the device.

Description

technical field [0001] The invention relates to a monitoring technology of equipment status signals, in particular to a high-speed signal acquisition and monitoring system and method applied to an electro-hydraulic servo system of a steelmaking and continuous casting production line. Background technique [0002] At present, in the steelmaking and continuous casting production lines of various iron and steel production enterprises, some control objects with high response speed requirements and complex control processes often use high-speed electro-hydraulic servo systems to achieve adjustment and control, such as continuous casting mold hydraulic vibration, And continuous casting crystallizer molten steel level control, etc. These high-speed and complex control processes usually require high control precision. Once the performance or state of the electro-hydraulic servo system deteriorates, it will easily lead to excessive precision or loss of control, resulting in continuou...
