Embodiment 1

[0021] A wind turbine online state monitoring and evaluation device includes a data acquisition and calculation module, a main controller module, and a bus communication interface module. The device uses a multi-CPU structure (see attached figure 1 ), ARM as the main controller, completes the system data acquisition channel configuration, human-computer interaction, and transmits the collected data and evaluation results via Ethernet or field bus. The DSP chip is used as the coprocessor of the ARM chip to collect the vibration, Multi-channel signals such as temperature, pressure, voltage, current signals and algorithm calculations.

[0022] 1. Data acquisition and calculation module (see attached image 3 ) Is a signal acquisition and arithmetic processing system with TMS320F2812DSP as the core. The analog acquisition module can sample 16 analog signals according to the system parameter configuration. The signals generated from on-site vibration, temperature, pressure, voltage, an...

Abstract

The invention discloses a device for on-line monitoring and evaluating state of an air blower. The device comprises a data collection and operation module, a master controller module and a communication interface module, wherein the data collection and operation module is used for collecting parameter information of vibration of the air blower, temperature, voltage, electrical current, pressure, and the like; vibration signals of the air flow are decomposed by adopting a method of multiwavelet; early failure characteristic signals are extracted; performance evaluation is performed by adopting state performance evaluation algorithm based on a cloud model; the collected signals of the temperature, the pressure, and the like are distinguished and displayed by the master controller; and the device is equipped with a plurality of communication interfaces, so that data exchange between information and factory control net and manufacturing execution system can be realized. Through adoption of the device, performance state of the air flow can be evaluated accurately, so that reasonable maintenance for the air flow is realized.

Description

Technical field [0001] The invention relates to the field of maintenance and fault diagnosis of electromechanical equipment, in particular to an online state monitoring and evaluation device for a fan. Background technique [0002] Fans that are widely used in process industries such as metallurgy and electric power are one of the large-scale rotary equipment. Their operating conditions are directly related to the safe and economic operation of the factory. Therefore, the requirements for the safety and economic performance of fans are becoming stricter. Therefore, the implementation of state monitoring and fault diagnosis of the fan is of great significance to the improvement of the safety status of the plant equipment system. At present, scholars at home and abroad have conducted in-depth research on the methods and technologies of fan fault diagnosis, and proposed methods such as signal processing fault diagnosis and data-driven fault diagnosis. But there are few studies on e...
