The present invention proposes a method, device and system for identifying, diagnosing and predicting abnormalities of massive data streams in a dispatching automation system. The method comprises the following steps: a lossless acquisition step, in which the power dispatching data is losslessly acquired and preprocessed to obtain a message information stream; a sample expansion step, in which the message information stream is further preprocessed and WGAN-GP is performed for sample expansion; an AI identification step, in which the expanded samples are input into a two-step detection method composed of a PCA+XGBoost and CNN+LSTM joint algorithm model to improve the problem of low recognition rate of traditional machine learning and an output result step. The method, device and system of the present invention do not require a large amount of manpower, are short in time, do not require a large amount of labeled data, and have high accuracy.

The invention discloses a small low-speed target detection radar and a use method, and the radar comprises a radio frequency front-end cascade module which is used for generating a first wave band radio frequency signal when the radar works in a first wave band and generating a second wave band radio frequency signal when the radar works in a second wave band; the antenna array plane module is connected with the radio frequency front-end cascade module; the antenna array plane module comprises a first wave band transmitting antenna unit used for transmitting a first wave band radio frequency signal to a target; the second wave band transmitting antenna unit is used for transmitting a second wave band radio frequency signal to the target; the dual-band receiving antenna unit is used for receiving a first echo signal corresponding to the first-band radio-frequency signal and a second echo signal corresponding to the second-band radio-frequency signal; and the radar signal processing module is connected with the dual-band receiving antenna unit and is used for calculating the distance, the speed, the horizontal angle and the pitching angle of the target according to the first echo signal or the second echo signal so as to efficiently and reliably detect the target.
