Embodiment Construction

[0017] The connection structure of each part of the system is as follows: figure 1 As shown, the on-site data collector 1 writes the collected vibration parameters into the server database 3 for storage through the internal communication system 2 , and the client 5 requests data access from the server database 3 through the external network system 4 .

[0018] The specific operation monitoring method is:

[0019] (1) When the steam turbine generator set is running, use the field data collector 1 to collect the field vibration data. The collected data is divided into two parts, one part is for client users to call real-time data, such as speed, vibration instantaneous value, etc.; the other part is for client users to call historical data, such as trend graphs, historical data lists, etc.

[0020] (2) Write the real-time data and historical data collected by the on-site data collector 1 into the server database 3 through the internal communication system 2, and the server data...

Abstract

The invention discloses a method and a system for rapidly and remotely monitoring vibration parameters of a steam turbine generator unit in an online manner. The system mainly consists of a data acquisition unit, an internal communication system, a database server, an external network and a client. The characteristic data acquired by processing the field vibration data through the acquisition unit and an original waveform are directly written into the server database through SQL (structured query language) in an optical fiber transmission mode, the data storage mode, DMA (direct memory access) data acquisition, multi-register data processing and other data processing methods are optimized, and the vibration parameters of the steam turbine generator unit are rapidly and remotely monitored in an online manner.

Description

technical field [0001] The invention relates to a method and system for fast and remote online monitoring of vibration parameters of a steam turbine generator set, belonging to the technical field of remote online monitoring of parameters. Background technique [0002] In recent years, many domestic thermal power plants are carrying out condition-based maintenance of equipment, and the premise of carrying out condition-based maintenance of equipment is to fully grasp and analyze the operating conditions of equipment to determine an appropriate maintenance strategy. The vibration of the turbogenerator unit is a comprehensive reflection of the current health status of the unit, and it is also one of the main reasons for the unplanned outage of the unit. Therefore, on-line vibration monitoring of the unit, timely and accurate analysis and diagnosis are not only required for maintenance, but also have important significance for preventing major accidents of the unit. Due to the...
