  • Patent number: 11921221
    Abstract: The present disclosure discloses a system for intelligently leveling with an automatic temperature control function and a method thereof. The system includes a handcart-type leveller, indoor GPS positioning devices, an AGV trolley temperature measuring device and a control system. The control system processes position parameters of the AGV trolley temperature measuring device and the handcart-type leveller; converts the position parameters for the handcart-type leveller into position parameters for a leveling region, controlling the AGV trolley temperature measuring device to arrive at a lower part of the leveling region by a control chip and measuring temperatures in the leveling region; controlling an operation status of the AGV trolley temperature measuring device and transmitting data with the AGV trolley temperature measuring device.

  • Publication number: 20220038256
    Abstract: The present invention discloses sequence encryption for refactoring a reconstructed-key: a set of compound logic is used to construct a chaotic computing structure to realize chaotic bit-segment stream sequence encryption. In the present invention, the chaotic computing structure is used to dispatch a bit fetching logic, a bit metabolic logic, a bit reconstruction logic and other computing logic units to pseudo-randomly refactor a construct source and a drive source segment by segment and the drive source is used to pseudo-randomly control the construct source to refactor key bit segments bit by bit so as to construct an infinite non-looping regenerated key bit segment sequence that “a picked construct source bit from staggered positions can be non-metabolized and from duplicated positions must be metabolized”.
