The invention discloses a probabilistic model-based equipment state dynamic self-adaptive alarm method. Based on the dynamic data of equipment operation, the probability model of the equipment state is constructed by using the probability neural network self-learning. The model adjusts its distribution profile with the operation of the equipment, and dynamically describes the change rule of the equipment state. Relying on the model, study the dynamic judgment rules of equipment status; at the same time, construct thresholds between different states to form an adaptive alarm line for equipment operation. The present invention ignores the traditional basis for dividing the operating status of on-site equipment according to various general standards, and finds the rules from the respective development history of the equipment, and can establish a status level for each equipment, each measuring point, and even each monitoring quantity Judgment basis, clearly divides the state of conventional equipment on site into three levels: normal state, fault state, and rapid deterioration state, and determines the measures that should be taken in the field for each state, laying a foundation for comprehensive evaluation of equipment state Base.

The invention discloses a foundation grouting method for offshore wind power and a foundation grouting work barge for offshore wind power. The foundation grouting method for offshore wind power comprises following steps: cleaning an inner wall of a grouting outer pipe and an outer wall of a grouting inner pipe, cleaning a grouting pipeline and pre-rinsing the grouting pipeline in advance, diluting grouting material into grouting liquid, pouring grouting liquid into a grouting channel between the inner wall of the grouting outer pipe and the outer wall of the grouting inner pipe by means of the grouting pipeline in order to finish grouting operation, monitoring condition of grouting liquid which is not poured during grouting operation and condition of grouting liquid overflowing from the grouting channel. Emergency measures should be taken if requirements are not met. The foundation grouting work barge for offshore wind power comprises a barge body, a material placing area, a dilution water supply pit, an electric power supply room, a connection hose, mixers, grouting pumps and a monitoring device. The material placing area, the dilution water supply pit, the electric power supply room, the connection hose, the mixers, the grouting pumps and the monitoring device are arranged on the barge body. The foundation grouting method for offshore wind power and the foundation grouting work barge for offshore wind power have definite guidance effect and can promote development of construction of an offshore wind plant in our country.

The invention discloses a method and a device for quantitative determination of paint surface flatness. The method comprises the following steps: S1, collecting low-coherence light interference spectra of positions on a paint surface at equal intervals one point after another, and obtaining a low-coherence light interference spectrum matrix of the positions of the paint surface; S2, calculating the phase difference [Delta]phi between the low-coherence light interference spectra of any two adjacent positions on the paint surface; S3, calculating a depth distance difference [Delta]z of the two adjacent positions according to the phase difference [Delta]phi; and S4, calculating the integral of the depth distance difference [Delta]z and obtaining the flatness quantitative distribution of the paint surface. The invention provides a brand new technology for automobile paint surface flatness determination, achieves quantitative determination of paint surface flatness, thus helps people understand the flatness situation of the paint surface more directly and concretely and find the cause of ups and downs of the paint surface, and provides clearer guidance for modification and coating techniques.
