  • Publication number: 20250146726
    Abstract: A load balancing method for two compressors. The two compressors are used in a refrigeration system and are driven coaxially by the same driving device. The method comprises the steps of obtaining parameters, determining balance, and controlling start/stop states. The parameters in the step of obtaining parameters are parameters related to the two compressors, such as a compressor suction side flow rate, or exhaust side flow rate, or suction side temperature; the step of determining balance comprises determining, on the basis of the obtained parameters related to the two compressors, whether load is balanced between the two compressors; the step of controlling start/top states comprises controlling the start/stop states of the two compressors according to whether the load is balanced. The method can monitor the load balance state of two compressors that are coaxially driven, thereby effectively avoiding failure of the refrigeration system caused by unbalanced loads of the compressors.

  • Publication number: 20220404460
    Abstract: A sensor calibration method and apparatus, and a storage medium are provided. In the method, multiple scene images and multiple first point clouds of a target scene are acquired by an image sensor and a radar sensor. A second point cloud of the target scene is constructed according to the multiple scene images. A first distance error between the image sensor and radar sensor is determined according to first feature point sets and a second feature point set. A second distance error of the radar sensor is determined according to multiple first feature point sets. A reprojection error of the image sensor is determined according to a first global position of the second feature point set in the global coordinate system and first image positions of pixel points corresponding to the second feature point set in the scene image. The radar sensor and image sensor are calibrated.
