The invention relates to the field of violation monitoring, in particular to violation behavior monitoring equipment and method based on dual prevention. The technical problems that in the prior art, a violation behavior monitoring method lacks a prediction analysis and risk prevention and control mechanism, so that the early warning capability and the prevention and control effect of a monitoring system are limited, and a passive response mode is mostly adopted, that is, the violation behavior can be found and recorded only after the violation behavior occurs, and early warning and prevention cannot be performed in advance are solved; according to the technical scheme, the violation behavior monitoring equipment based on dual prevention comprises a high-definition camera, a mounting rack and a central processing unit; according to the invention, by introducing a risk assessment mechanism, quantitative assessment is carried out on the properties and consequences of the violation behaviors, the hazard level of the violation behaviors is determined, a scientific basis is provided for subsequent treatment measures, potential risk behaviors are predicted through a machine learning algorithm, early warning and prevention and control are realized, and occurrence of the violation behaviors and accumulation of potential risks are effectively reduced.

The present application provides a kind of composition and preparation method and application for preventing cataract, macular lesion and diabetic retinopathy, belong to biological medicine technical field.The composition of the present application includes: nano active ingredient, plant extract, glycyrrhizic acid dipotassium, nicotinamide, taurine, ikdoin, caffeine and lutein;Plant extract is composed of wild chrysanthemum flower extract and gentian extract;Nano active ingredient is composed of nano-encapsulated astaxanthin and nanometer retinol.The composition of the present application effectively inhibits key pathological links such as lens protein oxidative denaturation, retinal pigment epithelial cell function decline and pathological angiogenesis by multi-dimensional synergistic mechanism of antioxidant-anti-inflammatory-vascular protection-metabolic regulation, thereby realizing the prevention and adjuvant therapy effect on three major blinding eye diseases of cataract, age-related macular degeneration and diabetic retinopathy.

The utility model provides a settlement displacement detection device relates to settlement detection technical field, including road bridge pier, pier foundation and settlement detection device foundation, be installed with detection stand on the settlement detection device foundation, the lateral wall of road bridge pier is installed with the fixing frame, the fixing frame passes through displacement frame and extends to the inside of detection stand, the top of displacement frame is located in the inside of detection stand and is equipped with early warning structure, the utility model discloses a first pressure sensor and second pressure sensor are set up, cooperate early warning structure, can when displacement reaches certain degree, through first pressure sensor triggers early warning signal, reminds relevant personnel to pay attention in advance when bridge settlement displacement occurs initially, along with settlement displacement further development, when reaches more serious degree, second pressure sensor triggers alarm signal, and this twice alarm mechanism realizes the prevention and warning to bridge settlement displacement, and effectively strengthens the security guarantee of bridge operation.

This invention relates to the field of aero-engine maintenance technology, and in particular to a method and structure for detecting the angle oscillation of an aero-engine main pump regulator that meets the performance requirements of the high-pressure guide vane. The method includes the following steps: a) First, connect the main pump regulator to be tested to the fixing mechanism on the testing device; b) Install the aero-engine's high-pressure compressor actuator on the corresponding high-pressure bracket of the testing device, and install the aero-engine's low-pressure compressor actuator on the corresponding low-pressure bracket of the testing device; c) Install the feedback mechanisms of the high-pressure compressor and low-pressure compressor on the testing device; d) Check the linearity and oscillation of the guide vane angle; e) Repeat step d again; f) If the linearity and oscillation of the guide vane angle are unqualified, return it to the repair or assembly process for troubleshooting; if the linearity and oscillation of the guide vane angle are qualified, the main pump regulator is delivered to the engine assembly and testing process.

The invention relates to a privilege simulation attack method and device, electronic equipment and a storage medium, and relates to the technical field of network security, and the method comprises the steps: forming a privilege attack thematic theoretical basis through multi-source information fusion analysis based on attack behavior data related to privilege access; constructing a privileged attack thematic model through an attack load, an attack mode, an attack means and path information based on a privileged attack thematic theory; the privilege attack thematic model is used for carrying out simulation attack on target assets in the attack target range environment to output a privilege thematic technical and tactical method; and executing a simulation attack test on the target enterprise asset information based on the privileged thematic technical-tactical method to generate a simulation evaluation report. According to the method and the device, the attack behavior is discovered and prevented in advance, the situation that detection rules are independently developed or updated for different products is avoided, the response period is shortened, novel threat behaviors are adapted in time, the problems of huge workload and key information omission caused by product switching are reduced, and the global threat situation awareness capability is formed.
