The invention belongs to the technical field of aircraft flight control, and particularly relates to an integrated control design method of ship-borne unmanned aerial vehicle arresting landing and escape re-flight. The integrated control design method comprises the steps of S1, designing a control strategy before landing; S2, designing a control strategy of ship-touching sliding; and S3, designinga control strategy of escape re-flight. The integrated control design method mainly solves the problems of arresting landing and escape re-flight of a ship-borne aircraft. An integrated control method is adopted in the longitudinal direction of successful landing and failed landing escape re-flight of the ship-borne unmanned aerial vehicle, other additional judgment conditions are not needed between the two conditions, and the timeliness and safety of escape re-flight when the ship-borne aircraft fails to land are guaranteed.

The invention discloses a two-factor authentication method based on a digital certificate and biological identification information. The main idea of the method is that a certificate authority (CA) digital certificate is transmitted to a mobile phone or a personal computer (PC) terminal of a user which is a normal user or a financial approval leader in a server such as a server of an accounting document management system, the digital certificate can pass the authentication of a third-party authority electronic authentication center, validity of the user is verified by the digital certificate, and the biological identification information is used as a respective private key in a digital certificate key pair which is used by the server and a client in the authentication process of the digital certificate to further ensure the security of authentication; and the biological information such as iris information and fingerprint information is identity inherent information and cannot be copied or stolen, so that the absolute security of authentication can be ensured.

A oil-air suspension and active suspension switching control circuit and a suspension oil cylinder, first of all: the structure of the suspension oil cylinder is improved, that is, the outer cylinder wall of the suspension oil cylinder is provided with oil ports at the upper and lower sides, and the inner cylinder is built in the center through hole of the upper end cover. , the wall of the inner cylinder is provided with two oil ports respectively connected to the inner rodless cavity and the inner rod cavity, the end of the inner cylinder located in the outer cylinder is connected to the outer piston located in the outer cylinder, and the inner One end of the cylinder rod located in the inner cylinder is connected with the inner piston, and one end located in the outer cylinder is fixedly connected with the lower end cover. The present invention adds an active suspension control circuit to the existing interconnected oil-air suspension switching control circuit, which is based on the improved suspension oil cylinder, and adopts left and right servo valves and left and right oil-gas recovery control valves to cooperate with it. Through the active suspension control loop, three control modes of oil-air control, active control and rigidity control of the suspension system can be realized, and the three control modes can be switched mutually without affecting each other.

The invention discloses a functional materia medica high-calcium element, in particular to a functional materia medica high-calcium element which has the nutrition health functions of strengthening stomach and promoting digestion, supplementing calcium and discharging lead, promoting growth and intelligence, replenishing qi and blood and is specially used for children and youths as well as a preparation method. The invention belongs to the field of nutrition and health food and is manufactured by taking lotus root powder, chrysanthemum powder, calcium powder, iron powder, zinc powder, vitamin C, taurine and casein phosphopeptide as the main materials. The manufacture technique is simple and convenient; the operability is high. The safety and the taste of the product are good; besides, the product has no bitter and iron fishy smell, does not stimulate gastrointestinal tracts, is easily eaten, is easily absorbed by a human body, has a plurality of nutrition health functions and provides the most effective nutrition help for the health growing of children and youths.

The invention provides an operation request processing method and system. The operation request processing method comprises the steps that after receiving an operation request message, a background system server generates a response message according to a first preset security class and sends the response message to a network terminal; after receiving the response message, the network terminal generates a feedback message according to a second preset security class and sends the feedback message to the background system server; after receiving the feedback message, the background system server executes an operation request. By conducting security classification on data to be transmitted, semi-transparency of communication data is realized, a part of the communication data are transmitted in the form of plaintexts, and the integrity and the safety of the data to be transmitted with a higher security class can also be guaranteed on the premises that the absolute security of the data to be transmitted with the highest security class is guaranteed and the plaintexts of the data to be transmitted with the higher security class and the plaintexts of the data to be transmitted with a lower security class are visible.

The invention discloses an implementation method based on a configuration type financial transaction short message verification code public component. The method includes determining and storing the binding relationship between specific services and SMS verification code template configuration; the back-end exposes HTTP interface services such as SMS verification code sending and verification to form a back-end component, and the back-end component exposes SMS verification code sending and verification services For front-end components to call; publish front-end components to the resource library through npm to form front-end components, other projects are installed directly through npm, and the front-end components can be used in the page after being introduced and activated. The invention solves the function redundancy problem of the system, improves the expansibility and isolation of the system, and is easy to maintain and upgrade; the short message verification code component can be used at the front end through simple configuration, and it can also be distinguished according to different incoming parameters. The difference of SMS verification codes for different business activities is eliminated; the absolute security of business activities is guaranteed.

This application belongs to the technical field of aircraft flight control, and in particular relates to an integrated control design method for ship-borne unmanned aerial vehicles to arrest landing and escape and go around, which includes step 1: designing the control strategy before landing; Run control strategy: Step 3: Design escape and go-around control strategies; this method mainly solves the problem of carrier-based aircraft intercepting landing and escaping and go-around. The integrated control method does not require additional judgment conditions between the two situations, ensuring the timeliness and safety of escape and go-around when the carrier-based aircraft fails to land on the ship.
