The invention relates to an access control method and system based on a zero-trust micro-gateway, and belongs to the technical field of information security. A zero-trust micro-gateway management center is established for a micro-service architecture, and a zero-trust micro-gateway strategy execution center is deployed on a container where each micro-service is located, that is, a containerized zero-trust micro-gateway firewall is established before each micro-service to realize network blocking of unauthorized access. The management center performs SPA authentication on a visitor of the micro-service, opens an authentication service port to an IP of the visitor after the SPA authentication is passed, receives an authentication request data packet of the visitor to perform access authentication, generates a dynamic access control strategy based on environment baseline data of the visitor after the access authentication is passed, and sends the dynamic access control strategy to the execution center; and the execution center controls the access of the visitor according to the access control strategy passing the verification. According to the scheme of the invention, the micro-service is hidden behind the zero-trust micro-gateway, thereby effectively achieving the hiding of the network by the application service, and improving the safety of the service.

The present application relates to the field of strong light search for ships, and specifically discloses a ship sea sweeping lamp and its production process, which includes a light source module, a control device and a shell assembly, wherein the shell assembly includes a base, a bracket rotatably connected to the base, and a shell fixedly connected to the bracket, wherein the shell is provided with a plurality of heat dissipation holes near the rear end, and the shell is provided with a plurality of groups of reflection areas near the front end, wherein the reflection areas include a plurality of waist-shaped grooves and a plurality of reflection grooves, and the plurality of waist-shaped grooves and the plurality of reflection grooves surround a circle. By providing waist-shaped grooves and reflection grooves, the present application can effectively destroy the continuity and regular shape of the shell, thereby changing the radar reflection characteristics of the lamp body, and this scattering effect helps to achieve the radar stealth effect of the lamp body.

Front cantilevers are arranged on the two sides of the front end of an unmanned aerial vehicle body in an extending mode correspondingly, the free ends of the front cantilevers are connected with upward front propellers, rear cantilevers are arranged on the two sides of the rear end of the unmanned aerial vehicle body, and downward rear propellers are arranged at the free ends of the rear cantilevers; a head camera is further arranged at the front end of the unmanned aerial vehicle body, front clamping jaw assemblies are arranged on the two sides of the head camera, a plurality of lower clamping jaw assemblies are arranged on the two side faces of the middle of the unmanned aerial vehicle body respectively, the root of each lower clamping jaw assembly is driven by a swing motor, and a front propeller, a rear propeller and the multiple swing motors are connected with a control module; when the unmanned aerial vehicle flies, the control module controls the swing motor to stop action and starts the front propeller and the rear propeller; when the unmanned aerial vehicle needs to advance on the ground surface, the control module controls the swing motor to start and close the front propeller and the rear propeller.

This invention relates to the field of hatch technology, specifically to a manufacturing method for an integrated composite material modular cabin hatch, comprising: Step 1, fabricating a main frame, inner skin, outer skin, and sealing structural components; Step 2, installing pre-embedded metal parts within the main frame, using screw connections and adhesive bonding; Step 3, cutting the core component according to the internal dimensions of the main frame, applying adhesive around the core component, and placing it inside the main frame; Step 4, placing the inner and outer skins on both sides of the main frame, connecting them with room temperature adhesive, pressing them firmly, and wiping away excess adhesive; Step 5, installing the sealing structural components around the main frame, using screw connections and adhesive bonding. The main frame, inner and outer skins, and sealing structural components manufactured using the above method have only 60% of the density of aluminum alloy and 20% of the density of steel, and the main frame is manufactured using an integrated molding process, which is simple.
