The invention provides an FPGA (Field Programmable Gate Array) based high-speed network strategy matching method. The method realizes utilization of relatively small storage space, and simultaneously is suitable for fast strategy matching processing in hardware, and further enables the performance of strategy matching processing to be irrelevant with the data volume of strategies. The FPGA based high-speed network strategy matching method employs a quintuple, supports accurate matching of the quintuple and IP-port range matching , and is stronger in functions and more diversified in matching conditions and matching modes than the traditional pure hardware manner; the strategy tree of the FPGA based high-speed network strategy matching method is a specific tree structure with a node length fixed at 512 bytes and the height of the tree layer fixed at 13, and aims at FPGA strategy matching; the logic processing of direct address positioning is simple and efficient, so that consumption of lots of time on the logical operation is avoided and the matching efficiency is greatly improved.

The invention discloses a product early-fault root cause recognition method based on fuzzy data processing. The method comprises the following steps of 1, constructing a product early-fault root cause relevance tree layer model; 2, constructing a potential fault root cause data model; 3, collecting product service life period quality and reliability data; 4, on the basis of the fault relevance tree layer model, a process target node and data fuzziness analysis are determined, and then node influence factors and fuzzy values are determined; 5, constructing a product early-fault root cause fuzzy data envelopment analysis model; 6, estimating an efficiency evaluation value of a fault relevance tree node; 7, fault relevance node relative weights are divided, and node priorities are ranked; 8, results are analyzed, and fault root cause recognition is completed. Development of the early fault root cause recognition technology under the early fault mechanism recognition cognition fuzzy environment is broken through, prevention measures are adopted for product design, technological design stage and other early fault forming stages, afterward treatment is changed into beforehand prevention, and the new idea is provided for early fault prevention and rectification.

The invention discloses an efficient RDF data storage and query system which adopts a composite index structure of a hash table and a hash tree and is used for storing RDF data. Wherein the compositeindex structure comprises a Hash layer serving as a first layer of Hash table and a tree layer serving as a second layer of Hash tree; Wherein the hash layer is a static hash table, and the tree layeris a dynamic hash tree, so that the query efficiency is improved; In the first layer, constructing a static hash table with the length of m; In the second layer, a Hash tree is dynamically constructed based on the prime number sequence; The system also utilizes a hash tree to solve the conflict problem in the hash table. Through the designed data storage query system, the RDF storage efficiency and the SPARQL query efficiency are improved, and various requirements in practical application are met.

The invention discloses an improved RCM analysis method, and a mechanical equipment integrity evaluation system based on the same. The improved RCM analysis method includes the steps: S1, dividing the boundary for an ocean platform mechanical equipment system, and the hierarchical structure tree for all the equipment; S2, determining the performance index of each equipment in the hierarchical structure tree layer by layer; S3, determining the importance evaluation index, and according to the importance evaluation index, performing importance evaluation on all the equipment, and dividing the equipment into important equipment and unimportant equipment; S4, determining the fault mode of the important equipment, performing FMECA analysis on the important equipment, and determining the fault reason of each important equipment and the influence; S5, establishing a maintenance logic decision graph, performing logic decision on the important equipment and the unimportant equipment, determining the maintenance method of the important equipment and the unimportant equipment, and generating a maintenance outline; and S6, according to the maintenance outline, making a maintenance scheme which can be directly implemented. The improved RCM analysis method introduces the mathematic model and algorithm into the overall analysis process to convert qualitative analysis into quantitative analysis so as to obtain a relatively more visual and accurate analysis result.

The invention relates to a service credibility assessment method oriented to internet of things manufacturing. The method comprises the steps that a credibility attribute set is built according to user demands; an attribute measuring method is defined, and credibility attribute weight allocation is solved to obtain an attribute weight allocation set; a credibility index tree is built according to the credibility attribute set and the attribute weight allocation set; credibility attributes capable of being directly measured are extracted; credibility evidences are collected from an assessment object over a time period, credibility attributes served at the current time period are assessed according to the credibility evidences and the measuring method of each credibility attribute, and a current assessment result is obtained; the current assessment result is amended by utilization a historical assessment result; derivation is carried out upwards from the bottom layer of the credibility index tree layer by layer according to the amended assessment result to work out a root node value, and the root node value serves as the service credibility attribute value. The internet of things manufacturing software and credibility of interaction of the internet of things manufacturing software are assessed through the built credibility index model, and software service and credibility of interaction of the software service are ensured.

The invention discloses a cultivation method of a colorful fragrant camellia tree. The method comprises the following steps: step one, selecting and cultivating a stock; step two, selecting and picking healthy branches with leafbuds of a fragrant camellia tree at one-year age as scions; and step three, designing positions, needing scion grafting, of branches of all layers of the camellia stock, coating the matched parts needing grafting of the stock with reagents, and selecting three kinds of fragrant camellia tree branches with different flower colors, flower types, and fragrances to carry out budding or sicon grafting so as to complete the grafting process. The budding grating is selected preferably. The colorful fragrant camellia trees prepared by using the cultivation method has advantages of high color survival rate, balanced growth, same-tree layered different flowering, and close-range clear aroma.

The invention discloses a multifunctional lighting measuring instrument for tree-shrub-herb layer plant morphological indexes, comprising a circular tree layer branch angle protractor, a shrub layer morphological index lighting measuring box, and an herb layer morphological index lighting measuring box.
