This invention discloses a remote verification method and system based on a multi-FPGA verification public cloud platform. The method includes: a user selecting a corresponding resource configuration module from multiple candidate resource configuration templates provided by the cloud platform; receiving the design source file uploaded by the user through an encrypted channel; performing logic synthesis, probe insertion, partitioning, mapping, and top module generation operations to complete the simulation configuration; acquiring and calling computing resources from the computing cluster; generating a bitstream file according to the simulation configuration; allocating corresponding resources from the resource pool according to the simulation configuration; configuring the switching architecture routing table; connecting the resources corresponding to the simulation configuration to build a hardware simulation execution environment; loading the generated bitstream file onto the FPGA chip allocated to the user; configuring the peripheral interface board; connecting the debugger to the peripheral and making it ready; and the user remotely logging into the debugger via a virtual network computing protocol to perform simulation and debugging operations to obtain waveform data, thus completing the remote verification.

This invention discloses a bio-based thermoplastic polyurethane coating material and a controlled-release fertilizer that are easily and rapidly degradable. The coating material comprises 0.8-2.0 parts of a bio-chain matrix and 0.5-1.5 parts of a chain reinforcing agent; the bio-chain matrix is ​​a mixture of pre-oxidized vegetable oil diol and bio-based polyester diol; the chain reinforcing agent is a mixture of a curing agent, a hardening agent, and a toughening agent. The bio-based thermoplastic polyurethane-coated controlled-release fertilizer comprises fertilizer granules and a bio-based thermoplastic polyurethane coating material sprayed onto the surface of the fertilizer granules; the amount of the bio-based thermoplastic polyurethane coating material sprayed is 0.8-10% of the mass of the fertilizer granules. This invention, through precise control of the coating material formulation, can achieve a combined improvement in the tensile strength and toughness of the bio-based thermoplastic coating material, thereby achieving a superior controlled-release effect and resolving the contradiction between the degradability and controlled-release performance of current bio-based polyurethane coating materials.

The application discloses a flexible track capable of being fixed in the air in the field of automatic hole making equipment, and comprises a track main body and vacuum suction cups arranged below the track main body, wherein the vacuum suction cups and the track main body are connected through connecting frames, the connecting frames are respectively provided with front connecting ends and rear connecting ends at front and rear ends along the extension direction of the track, and the rear connecting ends and the front connecting ends on the connecting frames of two adjacent vacuum suction cups can be matched and docked and can be fixed together through connecting pieces. At the starting point and the ending point of the track, the flexible track can be extended to outside the workpiece, the connecting frames in the air can be fixed, the connecting frames form rigid connection, and the hole making equipment can be moved to the suspended section to make holes in the blind hole making area. In addition, for the case that the middle part of the workpiece has a groove or a notch, the connecting frames above the groove or the notch can be rigidly connected, so that the stability and the hole making precision of the hole making equipment are not affected when the hole making equipment is moved above the groove or the notch.
