The present invention provides a high voltage circuit breaker switch-on and switch-off speed characteristic measurement method based on machine vision. While the motion of a high voltage circuit breaker is recorded, a high speed camera is used to shoot the color mark of the surface of an observed moving part, a recorded video image is processed and identified through a machine vision algorithm, the position coordinate of the observed object of each frame of image of a video relative to a reference point is determined, the movement track of the observed object is obtained, and thus the switch-on and switch-off speeds of a high voltage circuit breaker moving contact are calculated. The installation of a sensor in a mechanical mode is not needed, only the setting of a color reference mark at an observation point is needed, a sensor is not need to replace for different measurement objects, and only the change of the position of a reference mark is needed. In addition, the linear motion or rotation speed can be measured, the field application is facilitated, the influence of an environmental condition of the equipment is small, and the need of online measurement of power switch equipment such as a high voltage circuit breaker in a live operation can be satisfied.

The invention relates to the field of corrosion of steel bars in concrete and particularly relates to a method for predicting initial corrosion time of steel bars in concrete. The method comprises thefollowing steps: taking chloride ion diffusion coefficients as a random variables, determining a group of chloride ion diffusion coefficient data according to experiment, combining with a migration model of chloride ions in the concrete to obtain time data reaching critical concentration of the chloride ions when reaching a certain depth, and building a response surface of the chloride ion diffusion coefficient and the time reaching critical concentration of the chloride ions; actually measuring a group of time reaching the critical concentration of the chloride ions and obtaining a group ofnew chloride ion diffusion coefficients by using the response surface; combining the group of new chloride ion diffusion coefficients with the migration model of chloride ions in the concrete to obtain a group of initial corrosion time data of the steel bars in the steel bar depth, and counting to obtain the probability distribution of the initial corrosion time of the steel bars.

The invention relates to a high load trickling filter of the environmental protection technology field, which can backwash. Pretreated wastewater is sprayed evenly by a water distributor from a water inlet onto a strengthened water distributing layer on the uppermost of a novel high load biological filter which can backwash. After the secondary distribution of the strengthened water distributing layer, the inlet water reaches a filter media layer. Through the secondary distribution of the strengthened water distributing layer, inlet water reaches to a material filtering layer. Sewage is purified under the effect of a comprehensive purification function. Outlet water which passes through the main material filtering layer is discharged by a supporting layer into a water tank. When a filter tank operates for a period and the inside of the filtering material is blocked, eight blow vents and the water inlet and the water outlet of the filter tank are closed for the backwashing. The invention on one hand can effectively overcome defects of the prior art that the treatment effects are greatly influenced by hydraulic loads, the filter is easy to be blocked, etc. the treatment efficiency is greatly improved and the operation condition is improved. On the other hand, the invention has the characteristics of simple management, low capital construction and operation fee and no secondary pollution.
