The invention discloses a flame-proof treatment method of real silk fabrics by a biological enzyme method, belonging to the biotechnical field of spinning. The method disclosed by the invention aims to overcome the deficiencies that real silk fabrics in flame-proof treatment by conventional chemical methods are not high in washability, the real silk is easy to damage in high temperature baking, the whiteness of fiber products is easy to decrease and the like. According to the method disclosed by the invention, tyrosine residues in silk fibroin are oxidized to dopaquinone structures with stronger reactivity by means of the characteristic of tyrosinase which has a catalytic oxidation effect on the tyrosine residues in real silk fiber to promote a grafting reaction on an organophosphorus flame retardant containing a primary amine base and the dopaquinone structures, and the flame retardant function of the real silk fabrics is improved through a nitrogen-phosphorus synergistic effect, so that flame-proof treatment of the real silk fabrics by the biological enzyme method is realized. The method disclosed by the invention comprises the following process flows: real silk fabric pre-treatment, and catalyzation of the organophosphorus flame retardant containing the primary amine base by the tyrosinase to graft, water-washing and drying post-treatment. For the fabrics treated by the method disclosed by the invention, not only is the flame retardant performance improved, but also the mechanical properties of the fabrics are further enhanced. Compared with conventional chemical methods, with the adoption of flame-proof treatment by tyrosinase catalyzation on the real silk fabrics, the method is low in energy consumption, high in efficiency and less in pollution in the processing process and is beneficial to environment protection.

The invention discloses an experimental building management system based on the Internet of Things. Various technical means such as human body infrared recognition, fingerprint identification, face recognition and the like are provided, so that people entering an experiment building and even all laboratories can be strictly identified; meanwhile, the operation authority of the experimental instrument is limited by controlling the power supply of the experimental instrument; non-operating personnel are prevented from operating the experimental instrument; the damage to an experimental instrument is avoided; Through carrying out fingerprint identification on experiment operators, the power supply of corresponding experiment instruments is controlled according to the fingerprint identification result, so that personnel who do not operate the corresponding experiment instruments can be prevented from opening the experiment instruments to carry out experiment operation, and the defect thatthe experiment instruments are possibly damaged by non-professionals is avoided; the use of the experimental instrument is controlled by controlling the power supply of the experimental instrument, and the method is simple, effective and easy to implement.

The invention provides an air conditioner pedestal assembly and an air conditioner. The air conditioner pedestal assembly comprises a pedestal, a motor and an air channel assembly, wherein the motor is arranged on the pedestal and is suitable for being detachably connected with an impeller of the air channel assembly of the air conditioner, and the air channel assembly is suitable for being demounted from the pedestal under the situation that the motor is not demounted. The air conditioner pedestal assembly serves as an important module in the modular air conditioner, the motor is arranged onthe pedestal, the motor is detachably connected with the impeller of the air channel assembly of the air conditioner, the air channel assembly of the air conditioner can be integrally demounted from the pedestal under the situation that the motor is not demounted from the pedestal, in this way, the air channel assembly is integrally demounted from the pedestal assembly when the air channel assembly needs to be washed, it does not need to demount the motor from the pedestal, the situation that water enters the motor is prevented, and electric shocks are also avoided.

The invention discloses separation equipment which comprises a rack, an overturn material taking mechanism arranged on the rack, at least one feeding and conveying mechanism arranged on the rack and located at one side of the overturn material taking mechanism, at least one separation mechanism arranged on the rack and located at one side of the feeding and conveying mechanism, and at least one discharge mechanism arranged on the rack and located at one side of the separation mechanism. The separation equipment realizes batch taking and feeding of to-be-separated material during material separation and separation and discharge of the material after corresponding detection is completed, thus improving material separation efficiency; and furthermore, the separation equipment can avoid material damage defects caused by material taking, feeding and separating manners that the material is gripped by manpower with tweezers.

The present invention discloses a rechargeable watch in a watch technology field.
