The present invention discloses a heat exchange system and its control method and controller, wherein the heat exchange system comprises at least two heat exchangers, a first heat source and a second heat source connected to the heat exchangers through a pipeline, and a flow control device arranged in the pipeline for controlling the flow of the at least two heat exchangers, wherein the control method comprises: obtaining the pressure of the heat exchange system and / or the flow of the heat exchange system; when the obtained pressure of the heat exchange system is equal to or greater than the preset pressure of the first heat source, and / or when the obtained flow of the heat exchange system is equal to or less than the preset flow of the second heat source, increasing the opening of the opened flow control device and / or adjusting the opening quantity of the flow control device. The heat exchange system and its control method and controller provided by the present invention can improve the stability and reliability of the operation of the heat exchange system during operation.

The utility model discloses an OCA (Optical Clear Adhesive) with alignment holes, which comprises a light release film, an OCA body and a heavy release film which are sequentially stacked from bottom to top, and the light release film, the OCA body and the heavy release film are all square. The single-side boundary dimension of the OCA optical cement body is smaller than that of the light release film and that of the heavy release film, so that the light release film and the heavy release film form a single-layer area, and a first alignment through hole is formed in each of three vertex angles of the light release film located in the single-layer area. A second alignment through hole is formed in each of the three vertex angles of the heavy release film in the single-layer area, and the positions and the shapes of the three first alignment through holes correspond to those of the three second alignment through holes. If the OCA optical cement is placed reversely or inversely, the OCA optical cement cannot be placed into the alignment column to remind an operator, and a physical fool-proof effect is achieved.

The application discloses a kind of aviation flight state monitoring and fault early warning method based on multi-source data fusion, including multi-source data fusion, the data of same time period in flight state is collected, the influence of removing noise is adopted Kalman filtering algorithm, and according to 3 guidelines removes outlier, and the main characteristic parameters are extracted using grey correlation analysis method and are fused with multi-source data;Flight state monitoring and fault early warning, select the main characteristic parameter monitoring data of flight state related fault as the target parameter and model output of prediction model, and the state input of high correlation degree is used as input, and a support vector machine prediction model is established to predict the main characteristic parameters, compare the predicted value with the actual value, and realize its fault early warning through trend analysis.

This invention discloses a power control method, device, equipment, and storage medium for hybrid vehicles, relating to the field of vehicle power control technology. The method includes the following steps: determining the supply mode of the low-voltage auxiliary power supply based on the engine's starting method and operating status, and through the start-stop coordination of the generator and DC-DC converter. By coordinating the start-stop of the generator and DC-DC converter, the low-voltage auxiliary power supply of the hybrid vehicle can be used rationally, which can reduce engine fuel consumption while ensuring performance, and also avoid hardware damage or vehicle alarms, thereby improving vehicle reliability.
