Problems solved by technology

However, this mode requires a large amount of data transmission bandwidth. The main reason is that in order to ensure the effectiveness and stability of the analysis and diagnosis, the operating status data received by all sensors should be sent to the back-end system as much as possible.

Embodiment Construction

[0036] Please refer to figure 1 shown, figure 1 It is a schematic diagram of the abnormality detection device for power equipment of the present invention. The power equipment abnormality detection device 100 can be an embedded system chip or a data processing device such as a personal digital assistant (Personal Digital Assistant, PDA). The power equipment abnormality detection device 100 is disposed in a power equipment 200 and includes a sensing module 110 , a processing module 120 , an optimization processing module 130 and a classification diagnosis module 140 .

[0037] The sensing module 110 is used for sensing the power equipment 100 to obtain a plurality of operating signals. Taking a motor as an example, the sensing module 110 not only senses the vibration signal data of the power equipment 100 through the vibration level, but also obtains temperature, magnetic flux, and current. , speed, voltage and other running signals when the motor is running.

Abstract

The invention provides a power device anomalous detection device and a detection method thereof. The detection device includes a sensing module, a processing module, an optimizing module and a classifying diagnosis module. The sensing module is used for sensing a power device to obtain a plurality of operation signals. The processing module obtains a plurality of character values from the operation signals. The optimizing module establishes a plurality of factor groups by classifying the character values. The classifying diagnosis module connects with the optimizing module and sends a state signal according to a predetermined rule and the established factor groups. The detection method includes steps of using a signal processing method to obtain the character values from the power device; establishing the factor groups according to relevance of the character values; and obtaining the operation state of the power device through a neural network and an experience rule, and judging whether the operation state is normal or not according to the predetermined rule.

Description

technical field [0001] The invention relates to a monitoring and diagnosis for the operation of power equipment, in particular to a power equipment abnormality detection device and a detection method thereof. Background technique [0002] Generally speaking, before the failure of power equipment, there is often a decline in performance and an increase in energy consumption, but these phenomena do not immediately affect the operation of the equipment, so they are often not discovered by users. In addition to increasing the probability of failure and shortening the life of equipment, the reduction of power equipment efficiency and the increase of energy consumption have a negative impact on industrial competitiveness and environmental protection. [0003] Most of the diagnostic modes of power equipment (such as motors) use a sensor to sense the running state of the power equipment, and then transmit the sensed data to the back-end system through wired or wireless transmission ...
