The application discloses a coreless ring-shaped heat uniformizing plate, which comprises two housings arranged in an upper and lower mode, the two housings are connected to form a sealed cavity, a central region of the sealed cavity is an evaporation region, and a surrounding region of the sealed cavity is a condensation heat exchange region; a plurality of groove structures are arranged in a ring mode in the sealed cavity, a unidirectional valve system is arranged between two adjacent groove structures, an inlet of the unidirectional valve system is communicated with a tail end of a previous-stage groove structure located in the condensation heat exchange region, and an outlet of the unidirectional valve system is communicated with a head end of a next-stage groove structure located in the evaporation region, so that liquid working medium of the previous-stage groove structure flows to the next-stage groove structure, the groove structures are sequentially connected in a head-to-tail mode through the adjacent unidirectional valve systems, and an internal flow channel located in the sealed cavity is formed to supply unidirectional circulation of working medium. The application can solve the problems of manufacturing difficulty, insufficient capillary force, increased flow resistance and low heat transfer limit caused by a liquid absorbing core of a traditional heat uniformizing plate.

The application provides an FPGA-based EtherCAT master station topology dynamic control system, comprising: an EtherCAT master station integrated with an FPGA chip, the EtherCAT master station being configured with a main network port and a redundant network port; a plurality of EtherCAT slave stations connected in sequence, the main network port of the EtherCAT master station being connected to a first end slave station of the plurality of EtherCAT slave stations; the FPGA chip being used to confirm that a network topology formed by the EtherCAT master station and the EtherCAT slave stations is in a linear mode or a ring mode according to a connection state of the redundant network port; wherein in the linear mode, the redundant network port is in a disabled state, and in the ring mode, the redundant network port is connected to a last end slave station of the plurality of EtherCAT slave stations; and the FPGA chip is further used to control the connection state of the redundant network port to switch the network topology between the linear mode and the ring mode.

The application belongs to the field of processing of screw sleeves, and particularly relates to a centrifugal oil throwing device and a screw sleeve processing production line. The centrifugal oil throwing device comprises a rack, a box body and a rotating centrifugal mechanism. The box body is arranged on the rack. The rotating centrifugal mechanism comprises a driver arranged on the rack, a rotating disc arranged in the box body in a rotating mode, and a plurality of positioning structures arranged on the rotating disc in a ring mode and used for supporting and limiting movement of columnar workpieces. The driver is in driving connection with the rotating disc. The centrifugal oil throwing device provided in the application drives the rotating disc to rotate to provide centrifugal force. The plurality of positioning structures dispersively position the plurality of columnar workpieces, so that the columnar workpieces are prevented from colliding with each other. The position of the positioning structure is fixed, and imbalance is not easy to occur, so that safety is improved. The attached cooling lubricating liquid and residual cutting chips are thrown into the box body under the action of the centrifugal force, so that work efficiency is improved.

The application relates to a code ring and carrier ring deep cooperation-based adaptive tracking method and system and belongs to the technical field of signal tracking. The method comprises the following steps: a code ring and carrier ring deep cooperation-based tracking loop is constructed; when encountering a weak signal / strong interference environment, the normal carrier ring assists code ring mode switching to code ring assists carrier ring mode; at this time, code frequency and pseudo-range information output by the code ring are injected into the carrier ring as prior information, so that the carrier ring does not need to search the carrier frequency in a large range; meanwhile, a pre-stored channel fixed deviation is introduced to perform ionospheric delay compensation on the carrier phase; a more accurate carrier frequency deviation can be estimated according to the deviation between the ionospheric-compensated carrier phase and the current carrier phase, the carrier ring is quickly recovered to be locked, and therefore, the dynamic tracking capability and the anti-interference performance of the carrier ring are improved without increasing the hardware complexity, and the positioning availability of the receiver is improved.
