Beschreibung
Zusammenfassung:	The invention discloses a blast furnace top pressure abnormal change control method which comprises the following steps: acquiring blast furnace unit fault signal data, and selecting a TRT shutdown mode or a TRT non-shutdown mode according to the blast furnace unit fault signal data; in the TRT shutdown mode, the static blade opening degree is controlled to be closed, and the bypass valve is controlled to be opened by the corresponding opening degree according to the flow conversion result of the quick switching valve; quality code diagnosis is conducted on the first blast furnace top pressure measurement data, and if the credibility of the first blast furnace top pressure measurement data is normal, the first blast furnace top pressure measurement data participates in automatic static blade adjustment; if the credibility of the first blast furnace top pressure measurement data is abnormal, switching to other blast furnace top pressure measurement data or TRT inlet pressure data to participate in static blade
