The invention discloses a design method of a combined wing section blade of a horizontal shaft tidal current energy water turbine. The method comprises the steps of researching the hydrodynamic performance of a conventional wing section and the hydrodynamic performance of a bionic wing section separately, combining a conventional blade wing section with the bionic wing section according to the function of all blade elements in the blade, and designing out a combined wing section blade which is superior in performance; obtaining a three-dimensional digital model of a fish fin, selecting section contours of different positions of the fish fin as bionic fish-fin wing sections, selecting a bionic fish-fin wing section through analysis software, exporting the bionic fish-fin wing section and required two-dimensional coordinates of the conventional wing section, optimizing blade elements of the designed blade, obtaining parameters of each blade element, making the bionic wing section and the required conventional wing section correspond to the blade elements, converting the three-dimensional coordinates of the wing section into three-dimensional coordinate data, importing the three-dimensional coordinate data into three-dimensional design software, conducting setting-out treatment, and finally generating the combined wing section blade. By means of the design method, the hydrodynamic performance of the combined wing section blade is made to be superior, and the energy-obtaining efficiency of the water turbine is remarkably improved.

The invention discloses a method for dispatching and dispatching shared automatic driving vehicles. The dispatching method of the shared self-driving vehicles judges whether the idle self-driving vehicles in the dispatching area meet the dispatching conditions in the following manner: firstly, it is determined whether the vehicles in the area meet the acceptable walking distance; Select the vehicle with the same driving direction as the destination (terminal position) as the dispatch vehicle; if there is no vehicle that meets the acceptable walking distance, select the vehicle with the shortest dispatch time as the dispatch vehicle. The method of the invention can well adapt to the driving characteristics of the self-driving vehicle, and by introducing the walking distance of passengers, the success rate of car dispatching is improved and the mileage of the self-driving vehicle is reduced.

The invention discloses a power output switching circuit. Two enable ends of a PLC output interface connector are connected in parallel to form a chip operating voltage receiving end, tow enable ends of a load terminal connector are connected in parallel to form a chip operating voltage transmitting end, and loops of the PLC output interface connector and the load terminal connector are switched on and switched off by a switching loop. In the switching loop, a high-speed electronic switching circuit is composed of high-power field effect tubes to substitute a relay circuit with mechanical contacts, thereby being better adapted to characteristics of the PLC output interface for a refill processing machine and better conforming to actual loading requirements (inductive character, high powerand high speed). Since the contactless high-speed electronic switching circuit has no mechanical loss, the problem of short service life is solved, the maintenance cost is greatly lowered, and the down time is reduced simultaneously.

The invention discloses a magnetic flexible tactile sensing structure based on a folding magnetization method, which comprises a flexible main body containing a permanent magnet material, the flexible main body has a negative Poisson's ratio structure, and a set area of the flexible main body is subjected to folding magnetization treatment. The invention further discloses a sensor composed of the sensing structure. The sensor provided by the invention can be applied to sealed and wireless scenes, can detect the magnitude and position of force, and has a wide prospect in touch skin application of a robot. The sensing magnetic sheet based on the magnetic field and the Hall element are not in contact, and the touch sensor can also be used as an unconstrained touch sensor under the condition that a connecting line is difficult to establish for isolation. According to the invention, the magnetic sheet structure with the triangular hourglass structure is adopted, so that the magnetic signal change and the stress change of the small magnetic sheet can present a linear relationship, and the magnitude and the position of the force can be detected at the same time.
