The invention belongs to the technical field of positioning and navigation, and particularly relates to a line inspection method and system for unmanned aerial vehicle airborne power grid X-ray detection equipment. According to the method, a positioning unmanned aerial vehicle is used for determining a hovering point of a transportation unmanned aerial vehicle on a power transmission line, after the hovering point is sent to a positioning navigation unit, the positioning navigation unit carries out coordinate system unification and flight path planning, and the transportation unmanned aerial vehicle receives a flight instruction sent by the positioning navigation unit; carrying the power grid X-ray detection equipment to fly to a hovering point according to the path planning of the positioning navigation unit; and releasing the power grid X-ray detection equipment, analyzing the acquired X-ray image by the power grid X-ray detection equipment, and transporting the unmanned aerial vehicle recovery equipment after the acquisition task is completed. According to the invention, the difficulty in releasing and recovering the power grid X-ray detection equipment can be reduced, and the detection efficiency is improved.

The present application relates to a method, system, device and medium for real-time short-connection card battles, wherein the method includes: starting a game and entering the card-playing stage, when the first terminal has played cards and the second terminal has not played cards, polling the game information from the server through the first terminal to determine whether the second terminal has played cards within a preset time period; if the cards have been played, then synchronously storing the game information to the data storage areas of the first terminal and the second terminal respectively, and judging whether the game has ended based on the game information, if not, continuing to enter the card-playing stage to start a new round of games until the game ends; if the cards have not been played, the game ends. Through this application, the problem of excessive server load caused by data transmission based on HTTP short connections is solved, and it is achieved that the number of polling times required in the card function is reduced by changing the storage method of user interaction data without changing the short connection communication framework of the HTTP protocol.

The application provides a multi-unmanned aerial vehicle power transmission line inspection method and system based on compressed communication and FedADMM optimization, and belongs to the field of information transmission and intelligent control.The application mainly covers local updating, compressed transmission and total end aggregation of multi-unmanned aerial vehicle data.Firstly, a target function is generated for the collected data, a weight value is distributed, and a FedADMM optimization algorithm is executed to update the local data;in the compressed transmission process, the local data is compressed through a compressed communication algorithm and then transmitted to the total end;in the total end aggregation process, the FedADMM optimization algorithm is executed again, the data transmitted by the multi-unmanned aerial vehicles is aggregated by the total end, and the information of the total end is broadcasted to the multi-unmanned aerial vehicles to achieve the final consistent value.The application can ensure efficient cooperative inspection of the multi-unmanned aerial vehicles, guarantee efficient communication through data compression, realize consistency of communication information with the help of the optimization algorithm, and effectively improve the intelligent level and overall efficiency of power transmission line inspection.

The invention provides an intelligent centralized meter reading terminal and method for autonomously realizing certificate management and secure communication, and the method comprises the following steps: before leaving a factory, the intelligent centralized meter reading terminal writes a Root CA certificate in a one-time programmable region, applies to the Root CA for taking the terminal as Sub CA, and generates a signature certificate at the same time; on site, the intelligent centralized meter reading terminal autonomously carries out certificate initialization on the intelligent electric meter registered for the first time, and two subsequent real-time communication parties carry out bidirectional authentication and negotiate a session key to carry out encryption communication. Through autonomous certificate management and secure communication, the intelligent centralized meter reading terminal can autonomously perform certificate management and control on the hung intelligent electric meter and realize secure communication, layered management of certificates and complete independence of information security of each management and control area are realized, and the system is safer and more reliable.
