Title: Flow distribution control method, device, and apparatus for hydraulic system and hydraulic system
Inventor: WANG WEI
IPC: F15B13/02
Filed: 2022-03-23
Abstract: A flow distribution control method for a hydraulic system, the hydraulic system comprising N loops L1-LN. The flow distribution control method comprises the following steps: S1: comparing pressures P1-PN at an inlet of an actuator in each loop of the hydraulic system; S2: according to the comparison result, determining a loop Lp1 which requires flow compensation; and S3: conducting flow compensation on the loop Lp1 according to the theoretical flow of the loop Lp1 and an actual flow in the loop Lp1 which flows into the actuator, wherein the number of loops in the loop Lp1 is less than or equal to N. Also disclosed are a flow distribution control device and a flow distribution control apparatus for the hydraulic system, the hydraulic system and a non-transitory computer-readable medium. An electric control pressure pump and a flow supplementing valve are employed to replace a constant pressure difference valve, and the flow of all branches may be supplemented, thereby avoiding the phenomenon of unequal flow distribution being generated due to flow distribution characteristics of a pressure compensation system being affected by the overflow area of the constant pressure difference valve. The foregoing employs a flow compensation scheme, has a simple structure, is insensitive to pollution, and has low investment costs.

Abstract: The disclosure generally relates to scene graph generation. Scene graph captures rich semantic information of an image by representing objects and their relationships as nodes and edges of a graph and has several applications including image retrieval, action recognition, visual question answering, autonomous driving, robotics. However, to leverage scene graphs, computationally efficient scene graph generation methods are required, which is very challenging to generate due presence of a quadratic number of potential edges and computationally intensive/ non-scalable techniques for detecting the relationship between each object pair using the traditional approach. The disclosure proposes a combination of edge proposal neural network and the Graph neural network with spatial message passing (GNN-SMP) along with several techniques including a feature extraction technique, object detection technique, un-labelled graph generation technique and a scene graph generation technique to generate scene graphs.
