Abstract: A parallel data access method for massive remote-sensing images includes: 1) segmenting a remote-sensing image to be processed using a set grid system, data in each grid corresponding to a data block; 2) collecting a data access log of an underlying distributed object storage system Ceph in a past period of time, and measuring a load index of each Ceph cluster and a load index of each pool; 3) selecting a pool with a minimum load in a Ceph cluster with a minimum current load to serve as a storage position of a current data block, and writing each data block into a corresponding pool; 4) returning a data identifier dataid and a data access path of the remote-sensing image; and 5) storing metadata of each data block in a metadata database. The method can support rapid and high-concurrency read and write of large-area data of a grid data block.

Abstract: Some embodiments of the present disclosure provide an air sweeping assembly, an air regulating device and an air conditioner. The air sweeping assembly includes: a rotation shaft (10), the rotation shaft (10) being provided with blades (20) thereon; a driving device, the driving device including a fixing portion (31) and a driving portion disposed on the fixing portion (31); the driving portion being drivingly connected with the rotation shaft (10), and the driving portion being configured to drive the rotation shaft (10) to rotate; and a first position limiting member (40) disposed on the fixing portion (31); the first position limiting member (40) being configured to define an initial position of the rotation shaft (10) in a circumferential direction.

Abstract: An air conditioner indoor unit is provided. The air conditioner indoor unit includes: a base module, having a base part which is arranged with a fan motor; a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part. During mounting, pre-assembly is first performed and then general assembly is performed; in such manner, the time needed to assemble the whole unit may be reduced.
