Cutter residual life prediction method based on machine learning regression algorithm

The invention relates to the field of machine tool cutter remaining life prediction, and discloses a cutter residual life prediction method based on a machine learning regression algorithm. The cutterresidual life prediction method comprises two parts including model training and online life prediction. The model training comprises the steps of collecting original data of a complete life cycle and establishing a corresponding relation with the actual life of a cutter, preprocessing signals, extracting signal features to form feature vectors, performing cross validation to obtain an optimal cutter life model, and performing hyper-parameter adjustment and optimization. The online life prediction comprises real-time data acquisition, signal preprocessing, signal feature extraction to form afeature vector, input of THE optimal cutter life model based on optimal hyper-parameters and output of the residual life of the cutter. The number of eigenvalues extracted from each channel during model training is large, so that the training precision is high, the residual life of the cutter is accurately predicted, a residual life intelligent prediction model of the cutter is established, different regression models can be intelligently selected according to different working condition environments, and the model is good in generalization performance and high in portability.

Self-fireproof cement-base composite material

ActiveCN106630791AImprove the effectiveness of self-fire protectionRealize intelligent fire protectionTemperature controlFire protection
The invention provides a self-fireproof cement-base composite material which comprises a base material, wherein the base material is cement paste, mortar or ordinary concrete; high-temperature-triggered fireproof composite fibers and reinforcing fibers are doped into the base material; the high-temperature-triggered fireproof composite fibers are formed by wrapping an outer protective layer capable of melting at high temperature outside a fireproof core material capable of foaming and expanding to implement heat insulation and flame retardancy at high temperature; and when the base material contacts high temperature, the outer protective layer of all the high-temperature-triggered fireproof composite fibers is heated and molten to form the network passages through which the fireproof core material can spill over. Compared with the common cement base material, the temperature control and refractory capacities of the composite material structure can be sufficiently enhanced under the condition of not lowering the structural strength and rigidity, thereby better implementing synchronization between blowout prevention and heat insulation and intelligent fireproofing under fire hazard heat triggering. The self-fireproof cement-base composite material has the advantages of favorable durability and high long-term economic benefits, and is suitable for complete life cycle fire protection design of high-rise buildings, bridges, tunnels and other industrial buildings as well as civil buildings and transport facility structures.

Digital accumulator battery

The invention relates to an accumulator battery, in particular to an accumulator battery digitizing real-time status measuring and control data of the accumulator battery and transmitting the data to an adaptive charger to realize digitalization of measuring and control in the charging process. Parameter setting in the charging process is a deciding factor of the service life of the accumulator battery along a vehicle; in particular, charging voltage adapts to continuous changes of an internal microstructure of the accumulator battery and external environmental temperature; and in order to ensure that a proper charging process is always kept in the complete life cycle of the accumulator battery, the charger is required to have the capacity of automatically adapting to the changes, so that the accumulator battery is required to be capable of outputting the real-time status measuring and control data to provide support for the charging process. Because related physical descriptors are weak, effective perception and reliable transmission are master keys of success. Therefore, the accumulator battery provides a digitization proposal, comprises a measuring and control module, interface specification and a packaging cavity, and is applicable to electric automobiles and electric bicycles with overlong series charging.

Method for breeding hepialus ovum by using geothermal warm spring on qinghai tibet plateau

This invention involves a method of propagating and breeding the Hepialus egg in Qinghai-Tibet Plateau utilizing geoheat hot spring. The method included establishing greenhouse Hepialus captive market in Hepialus insects suitable habitat near the geoheat hot spring generation place in Qinghai-Tibet Plateau; in winter and spring using the geoheat hot spring water to control the temperature of the greenhouse to stay between 10DEG C+-6DEG C and through lowering natural enemies hazards of Hepialus to promote herbs and / or shrubs inside the greenhouse Hepialus captive market to maintain good plant growth and form developed vegetation tender roots system; meanwhile through the releasing of Hepialus eggs, larvae and / or pupae, upgrading quantity and density of captive Hepialus; after Hepialus experiencing a complete life cycle of generation, the Hepialus larvae grows from instar 1 to the instar ranges from 6-8 only needs 345d-390d, and in May of the following year they pupate, and between June ~ August finish eclosion and grow to imagoes, adult Hepialus can be caught massively and their fertilized eggs after mating can be harvested too. The harvested Hepialus egg can be used as worm seed of Hepialus for artificial breeding or worm seed for Hepialus breeding in Qinghai-Tibet Plateau.
