This invention provides a network protocol vulnerability detection method and system based on message sequence attribution optimization, addressing the problems of existing gray-box fuzzing methods for network protocols in three aspects: message sequence attribution strategy, message sequence evaluation and selection, and selection of mutation point locations in message sequences. The method includes: acquiring the target code of the protocol under test; using the protocol under test for communication; collecting communication traffic; generating an initial message sequence set; performing fuzzing on the protocol under test; collecting code coverage information and status feedback information generated during the runtime of the protocol entity under test, and determining whether the currently tested message sequence is an interesting message sequence; and then performing the next round of fuzzing. This invention is applicable to all network protocol fuzzing tools based on AFLNET improvements and has advantages such as simple implementation principle, strong code coverage and vulnerability discovery capabilities.

This utility model discloses a rainwater collection device for vegetable cultivation, relating to the field of rainwater collection devices, including a water storage tank; the water storage tank is equipped with a partition, which divides the interior of the water storage tank into an upper conditioning zone and a lower storage zone; a stirring mechanism is installed in the middle of the top surface of the partition; a drain outlet is provided on the surface of the partition, and an electric sealing plate is hinged to the drain outlet; a water quality pH meter is installed on the top surface of the partition; a support rod is installed on the top surface of the partition, with the top of the support rod located above the water storage tank and equipped with a water purification mechanism; before storing and collecting rainwater, this rainwater collection device for vegetable cultivation will test the pH value of the rainwater. If the pH value meets the standard, it will be directly stored and collected; if it slightly exceeds the standard, a purification agent will be added to treat it until it meets the standard before storage and collection; if it seriously exceeds the standard, collection will be canceled and the rainwater will be directly discharged, which helps to reduce costs and maximize profits.

This invention discloses a multi-winding motor conductive ring structure, stator, and wind turbine generator. The motor conductive ring structure includes U, V, and W phase conductive ring groups. These three phase groups are arranged in rings from the outside inwards, with spacing between them, and are located on the same horizontal plane. Each phase group consists of 2N full-circle windings and 2N minor-arc windings. The virtual circle spacing formed by every two minor-arc windings is located between two full-circle windings. All conductive rings are located on a concentric circle, forming 4N sets of windings, evenly divided into two groups. Each group is individually connected to a corresponding converter. This invention divides multiple sets of windings into two equal parts. By combining full-circle windings and minor-arc windings, the winding current located within the two semicircles is introduced into the same converter, achieving redundancy design and uniform motor stress, avoiding vibration, noise, and other faults. It also reduces axial length and material usage, thereby reducing the unit's weight and manufacturing cost.

This invention discloses a method and system for determining differentiated subsidy amounts for emission reduction in port and shipping enterprises. Belonging to the field of emission reduction assessment technology, the method includes: acquiring key parameters of the port and shipping supply chain; classifying the dominant structural types of ports and shipping companies; obtaining information on emission reduction subsidies to shipping companies and green subsidies to shippers, and constructing a game model for dual subsidies; solving the game model to obtain the range of subsidy coefficients; and determining differentiated subsidy amounts based on emission reduction targets. This invention addresses the differences in power structures within the port and shipping supply chain, designs a dual subsidy mechanism that considers both shipping companies and shippers, clarifies scientifically reasonable subsidy amounts and coefficient ranges, and improves emission reduction effectiveness and supply chain efficiency.
