The invention discloses a transmission method for dynamic position information. The transmission method comprises the following steps: when the current electric quantity of portable equipment lower than a preset electric quantity threshold is detected, acquiring wireless electromagnetic waves which are acquired by an antenna module and exist in a living space; receiving current position information acquired by a wireless positioning module, and encoding the current position information to obtain binary information; converting the wireless electromagnetic waves into electric energy, controlling a switch contact of the antenna module by using electric energy according to the binary information, so as to adjust a resistance value of the antenna, and enabling two state changes of the resistance value of the antenna to be consistent with the binary information; transmitting wireless electromagnetic waves by the antenna module with an adjusted resistance value of the antenna resistance. The invention also provides a transmission device for the dynamic position information and a terminal. By adopting the embodiment of the invention, the position information is transmitted by using existing wireless electromagnetic waves in the living space, so that electric quantity of the portable equipment can be reduced, and an effective transmission process of information of the portable equipment is prolonged to a great degree.

A gulf stream electric generator including a first funnel, a second opposite funnel, a propeller, and an electric turbine. The first funnel is a funnel and is placed such that the narrow end connects to an elongated tube. The second funnel is connected to a second end of the elongated tube such that the narrow end is connected to the tube. A propeller is placed within the elongated tube. The propeller is operable coupled to an electric turbine generator. The electric turbine will create an electric charge and send it to a power station for distribution.

The invention relates to an intelligent gasket manufacturing method based on functionalized micro-nano fiber micro-nano structured arrangement. The method comprises the following steps: putting micro-nano scale fibers into a matrix solution, and uniformly dispersing the fibers to obtain a precursor solution containing functionalized micro-nano fibers; putting the precursor solution into a gasket mold; naturally leveling the solution in the mold; applying a structured alternating-current electric field to the solution in the mold by using a signal generator and a structural interdigital electrode, so that the fibers in the solution are directionally/localizedly arranged under the action of electric field force; before the solution is solidified, introducing wires into the two ends of the mold; curing and molding the solution in a container, and completely fixing the arranged fibers and wires in a gasket; and demolding the cured material to obtain an intelligent gasket. When the intelligent gasket is applied to bolt connection and if the pre-tightening state of a bolt is changed, an output electric signal of the intelligent gasket is changed, and therefore the change of the pre-tightening force of the bolt is deduced. The method has the advantages of simple preparation process, high efficiency, accurate monitoring and the like.

The embodiments of the invention provide a defrosting control method and device, an air conditioner and a storage medium, and relates to the technical field of air conditioners. The method is characterized in that when the air conditioner enters a defrosting mode, an operation parameter of the air conditioner and a current current threshold value of a motor are obtained, an actual current threshold value of the motor is determined according to the operation parameter and the current current threshold value, and an input voltage of the motor is adjusted on the basis of the actual current threshold value and a preset reference rotating speed of the motor, so as to improve the heating power of a compressor. According to the method, the actual current threshold value of the motor is determined, and the input voltage of the motor is adjusted on the basis of the actual current threshold value and the preset reference rotating speed of the motor, so that an actual current of the motor is close to the actual current threshold value, and an actual rotating speed of the motor is close to the reference rotating speed of the motor; and therefore, the heating power of the compressor is improved in a defrosting process of the air conditioner, defrosting is accelerated, the defrosting time is shortened, and user experience is improved.

The invention provides an electric multifunctional catering vending vehicle. According to the technical scheme, the compartment structure of the catering vending truck is improved in a centralized mode. Specifically, an opening is formed in the top end of the compartment, and the movable top plate located at the opening can be driven by the direct-current electric push rod to do lifting motion, so that opening or closing of the top end of the compartment is controlled, an ascending channel can be provided for emission of smoke in the compartment, and smoke overflowing is accelerated. Besides, a clamping type door plate fixing mode is abandoned, the turnover door is hinged to the window, and a hydraulic rod is used for supporting, so that opening and closing of the window are more convenient, and better stability is achieved after the window is opened or closed. The compartment structure is fully optimized, the using effect is improved to a certain degree, and the compartment structure has outstanding popularization prospects.
