The invention discloses a subsynchronous resonance suppression method, device, storage medium and processor. Wherein, the method includes: determining the first control parameter of the additional excitation damping controller and the second control parameter of the machine-side subsynchronous damping controller, wherein the first control parameter includes the gain and the gain of each control loop of the additional excitation damping controller The phase shift time constant, the second control parameter includes the gain of each control loop of the subsynchronous damping controller at the machine end, the phase shift time constant and the phase change parameter; according to the first control parameter and the second control parameter, the additional excitation damping controller is suppressed Subsynchronous resonance with the circuit where the machine-side subsynchronous damping controller is located. The invention solves the technical problem in the related art that a separate controller parameter is used to suppress the sub-synchronous resonance, resulting in poor effect.

The embodiments of the invention disclose a synergic photograph processing method and device and a photograph processing method and device. The synergic photograph processing method comprises that a first photographing device receives a synergic photograph preview image transmitted by a second photographing device; if determining that the synergic photograph preview image and a local photograph preview image do not meet association conditions, the first photographing device adjusts a local camera; if determining that the synergic photograph preview image and the local photograph preview image meet the association conditions, the first photographing device collaborates with the second photographing device to complete the photographing process. The photograph processing method comprises that the second photographing device obtain a local photograph preview image; the second photographing device transmits the local photograph preview image to the first photographing device; the second photographing device enables a local shutter event according to a synchronization completing signal transmitted from the first photographing device. The synergic photograph processing method and device and the photograph processing method and device optimize existing panoramic picture generating technology and improve the synthesis effects of panoramic pictures.

The invention discloses a vehicle state estimation method and device, electronic equipment, a storage medium and a vehicle. The vehicle state estimation method comprises the following steps: obtainingan image and identifying vehicle position information; and performing state estimation on the vehicle according to a fusion filter unit and the vehicle position information. The vehicle state estimation method solves the technical problem that the vehicle state estimation method is not good in effect. An improved vehicle speed and track estimation method is realized based on the fusion filter according to the characteristic that noise and measured noise statistic characteristics continuously change in a vehicle travelling process. Accuracy and robustness of vehicle state estimation are improved in a noise statistical signal conversion environment.

The present application discloses a target tracking method and device. The method includes extracting image features in an image target candidate area of ​​a video frame, and outputting an initial response value; smoothing the initial response value of the video frame; and updating the response value to determine the position information of the target in the video frame. The present application solves the technical problem of poor effect of the target tracking method. Through the method of this application, the output response of the network will often appear multi-peak and drift due to complex target states such as scale transformation and sudden movement. By fully considering the similarity relationship between adjacent superpixel blocks of the image, The relationship is used to constrain the initial response value, suppress the drift phenomenon in the tracking process, and then correct the position information of the target. Furthermore, the tracking accuracy and tracking efficiency of the object tracking method are improved.

The application discloses a wire harness winding method. The method includes detecting whether there is a copper wire to be wound on the winding group; if there is a copper wire to be wound on the winding group, then controlling the linear motion mechanism to drive the copper wire to perform linear motion according to a preset track through a screw rod; controlling the rotation The movement mechanism drives the copper wire to perform rotational movement according to a preset track through a motor. The application solves the technical problem that the effect of the wire harness winding method is not good. Through the application, automatic winding can be realized quickly, accurately and efficiently, which can effectively improve production efficiency, and the quality of machine winding is much higher than that of manual winding.

The invention proposes an interactive service recommendation method with dual interaction relationship and attention mechanism, the core of which is a service call prediction model. The model includes: using the Google Inception network-based text feature extractor and the graph embedding technology node2vec to extract the content features and call features of Web applications and services; based on the attention mechanism and multi-layer perceptron, respectively learn the Web applications to be developed , the content interaction and call interaction between the selected service and the candidate service; the above two interactions are integrated based on the multi-layer perceptron; the softmax function is used to predict the possibility that the developer selects the current candidate service as the component service. The interactive service recommendation method proposed by the present invention includes: using the above model to predict the score of each candidate service; recommending the N candidate services with the highest predicted scores to the developer; after the developer selects several component services, the recommendation process enters the next step round; repeat the above steps until the developer's requirements are fully realized.

The application discloses an order processing method and device. The method includes judging whether the available inventory quantity of the commodity in the order meets the commodity quantity required by the user; screening out the available inventory quantity according to the coordination rules to obtain the commodity inventory coordination result; and displaying that the available inventory quantity of the commodity in the judgment order satisfies the The product inventory allocation result when the user needs the product quantity. This application solves the technical problem of poor order processing methods. Through the method of the present application, when the customer service (OMS) coordinates the order, the execution of the coordination logic can be automatically completed and displayed to the customer service. Furthermore, this application is applicable in the field of medical products.
