This invention belongs to the field of edge computing technology, and particularly relates to an offloading and resource allocation method for heterogeneous edge computing networks based on information age. The invention includes: performing federated learning based on the experience of each mobile device; updating the local neural network of each mobile device based on the global neural network parameters obtained from the federated learning; training the local neural network and using the trained local neural network to output the offloading decision for the task corresponding to the current time slot; adjusting offloading decisions that do not meet energy consumption constraints using an elite-preserving genetic algorithm; calculating the computing and bandwidth resources allocated by each base station to each mobile device; executing the offloading decision and computing and bandwidth resource allocation tasks; and calculating the reward for each mobile device. This invention reduces the complexity of problem solving and ensures strict compliance with energy consumption constraints through a secure learning mechanism, significantly improving the convergence speed and robustness of the strategy.

The utility model discloses a kind of polishing devices of projector lens cover processing, it is related to projector processing technical field, the utility model includes protection box, the inner wall of protection box is equipped with discharge opening, the utility model is moved to the bottom of positioning ring by being equipped with spring and extension rod when placing plate is with unprocessed material, since the area of positioning ring is greater than positioning plate, therefore, positioning ring will be prior to top protective plate contact, so that top protective plate pushes connecting plate to make it push extension rod upwards and moves, and extrude spring inside hollow stem, push extension rod downwards using the elasticity of spring to make the close contact of the grinding disc bottom of connecting plate and material, so that grinding disc removes burr on the surface of material, reaches by the elasticity of spring let down moving extension rod makes grinding disc and material contact, prevent the problem that different height due to material, therefore polishing portion cannot effectively and material closely contact, prone to cause burr of material cannot be polished completely.

In order to solve the problem that the existing time series prediction method cannot extract multi-scale information and the dependence between variables at the same time, a time series prediction method based on a multi-scale network is provided.The method first constructs a prediction model MSLA (Multi-scale and Local Attention), which uses a multi-scale network to extract information at different scales of data;secondly, the correlation information between variables is extracted through a local attention module;and then the weighted fusion is carried out through a feature fusion module;finally, the prediction is carried out.The prediction model achieves good results under different real scene data sets, and the model provided by the application can provide more accurate prediction results compared with other models through experimental verification, and good experimental results are achieved in the multi-scene experiment, which shows good generalization ability and has great application prospect in the civil aviation field.
