The invention discloses a method for controlling the active power of a hydroelectric unit in a single recommended operation area, and belongs to the technical field of hydroelectric power generation control. Divide the automatic power generation control function into the power station-level AGC module, the unit-level PLC module and the unit-level governor module and then assign tasks, determine the parameters, assignment relationships and dependencies; establish all possible distribution modes and corresponding combinations that include AGC control units The intermediate table of the operation interval determines the optimal unit distribution mode of the units put into AGC control, and calculates the single-unit AGC active power distribution value, and performs the active power control of the hydroelectric unit in the single-recommended operation area. It is suitable for hydropower stations where the intervals are divided into vibration zone 1→restricted operation zone→vibration zone 2→recommended operation zone from low to high. It can quickly calculate the single-unit AGC active power of each unit according to the total active power setting value of the hydropower station. The distribution value and the active power setting value of a single unit can meet the operation requirements of the unit avoiding the vibration area and the restricted operation area at the same time.

The invention relates to a method to accelerate processor to read / write register and its device, mainly using processor to externally connect up with an extended memory and adopting MEMORY MAPPING mode to map register address established in the extended memory with idle SFR address in the processor, and also using a sign switch processor as integrated computer emulation (ICE) mode or normal operating mode, and the processor still uses external data transmission instruction as in ICE mode and internal one as in normal operating mode to read / write external register, respectively.

The invention discloses a light guide structure, a display device and a use method. The light guide structure includes a housing; an opening formed on the housing; a first light guide fiber, a photosensitive sensor, a second guide optical fiber, compensation module; wherein the first light guide fiber is used to guide the light entering the opening to the photosensitive sensor; the second light guide fiber is used to guide the image displayed by the compensation module to the opening. The embodiment provided by the present invention is applied to a display device, and realizes the hidden design of the lens under the screen through the light guide structure, and retains the display function of the original area while satisfying the camera under the screen of the display device.

The invention provides a non-linked carrier transferring mechanism, a carrier transferring method and a shoe upper laminating device comprising the non-linked carrier transferring mechanism. The carrier transferring mechanism comprises a controller and N non-linked carriers, each carrier corresponds to one station, and the controller controls each carrier to independently rotate and can make M carriers to be transferred to other stations from original stations, wherein N and M are natural numbers, M is smaller than or equal to N, and N is greater than 1. The carrier transferring method comprises the steps that the controller determines the carriers to be transferred, then the carriers to be transferred are subjected to positioning unlocking and movement locking and then are transferred to other stations, and movement unlocking and positioning locking are conducted. The shoe upper laminating device comprises the carrier transferring mechanism, a heating and pressurizing device and a cooling and pressurizing device. It is not needed to prepare materials after hot pressing is finished, neither material preparation nor carrier transferring is neglected, the dilemma problem is solved, and the product quality and production efficiency are improved.

The invention discloses an elevator or elevator relieving device, which is characterized by the following: at least a plurality of alternate coil assembly is installed in permanent magnetism drive motor; the alternate electric power supply power of alternate coil assembly makes the alternate coil assembly and base coil of permanent magnetism drive motor separate or act in conjunction; the delayed-elevating gear is installed; the chief axis sleeve of delayed-elevating gear installs immobilizing member; the spinning by one side of controlling device controlling the chief axis of delayed-elevating device makes the immobilizing member relieve brake equipment or spark electromagnetic contactors; which makes the elevator or elevator wagon lift and stop; the controlling device is handed by electromagnetic actuator or hand wrench grip which is fit for reset device of up-down tunnel every floor making the controlling device reset to reflex the relative relation between immobilizing member and brake equipment and electromagnetic contactors; making the wagon delayed-brake till stop is useful for the insiders to open the door to relieve easily.

The invention provides a pedestrian feature extraction and representing method based on a region sparse integration passage. The method includes the steps that firstly, spatial arrangement information, which is evenly sampled at random, of regions and sub-regions is used; secondly, feature passage values, inheriting various kinds of heterogeneous source information, in the sub-regions are extracted; thirdly, features of the sub-regions are fused into features of the regions; finally, all the features of the regions are connected in a cascaded mode to obtain pedestrian descriptors. By means of the pedestrian feature extraction and representing method, the dilemma choice problem in pedestrian feature extraction and representing is solved under a unified framework. The spatial arrangement information and the various kinds of heterogeneous source information are included. According to the pedestrian feature extraction and representing method, the fine-grained spatial arrangement information of the regions and the sub-regions is used, the various kinds of heterogeneous source information in the sub-regions is naturally integrated, and therefore consideration is given to descriptiveness and flexibility.

The invention discloses a device for detecting abnormal sounds of an audio, and relates to the car audio detection field. The device comprises a soundproof cover, a vibration gauge, a noise detection device and an analysis instrument, wherein the audio is covered with the soundproof cover; the soundproof cover and the audio are fixed on a working table at the upper part of the vibration gauge; the soundproof cover is used for isolating external sounds; an inspection hole is formed in the soundproof cover; the noise detection device is arranged inside the soundproof cover; and the noise detection device penetrates through the inspection hole and is connected with the analysis instrument. According to the device, an awkward situation that abnormal sounds inside the audio can be heard only by manually rocking the audio can be effectively solved, a blank of the detection of the abnormal sounds inside the audio is filled, and support foundations can be provided for developing and designing a novel audio product, and detecting and analyzing noise and vibration data.
