The invention provides a gateway configuration method and device, electronic equipment and a readable storage medium, and is applied to the technical field of vehicles. The method comprises the steps of firstly obtaining a description file of each network segment connected with a gateway, then determining target messages in a plurality of network segments based on message information in a plurality of description files, generating routing information of the target messages according to the message information of the target messages stored in the plurality of description files, and configuring the routing information for the gateway, and the gateway can transmit the target message among different network segments based on the routing information. According to the gateway configuration method provided by the invention, the automatic configuration of the routing information can be realized, so that the time spent in the routing information configuration process can be shortened, and the software development efficiency of the gateway can be improved.

The present disclosure provides a method and device for automatically matching images to a presentation, an apparatus, and a storage medium, and relates to the technical field of data processing, in particular to the technical field of artificial intelligence, deep learning, natural language understanding, etc. The specific implementation scheme is as follows: multiple description sentences are extracted from a page to be matched with an image in a presentation; a candidate image set is obtained by matching each description sentence with a corresponding candidate image; the matching degree of each candidate image in the candidate image set with the page to be matched with an image is determined; and a target image is selected for the page to be matched with an image based on the matching degree of each candidate image with the page to be matched with an image, and the target image is used as an illustration for the page to be matched with an image. In the embodiment of the present disclosure, by extracting multiple description sentences, the page to be matched with an image can be automatically and accurately selected for the appropriate illustration.

The application provides a mobile robot trajectory tracking system and method in a wireless packet loss environment, wherein in the wireless packet loss environment, current state information of the mobile robot is encoded and transmitted to a remote control terminal based on the Chinese remainder theorem and multi-description coding; the remote control terminal takes minimizing trajectory tracking error as a target, takes limited angular velocity of the mobile robot as a condition, generates optimal control instructions by using model predictive control according to input reference trajectory and reference angular velocity and current state estimation of the mobile robot obtained by wireless transmission and decoding, and encodes and transmits the optimal control instructions to an executing mechanism of the robot based on the Chinese remainder theorem and multi-description coding, so that the robot completes a desired trajectory tracking task in the wireless packet loss environment and the trajectory tracking error is minimized.
