The amount of intrusion detection calculation based on software is heavy, which can not satisfy the needs of modern network bandwidth; the intrusion detection technology based on hardware is an ideal method for accelerating network processing. The thesis proposes a design scheme for FPGA-based real time intrusion detection NIC, and introduces the hardware and software structure of the system n details. The system communicates with the operation system directly via PCI bus, achieves the organic combination of software detection and hardware detection, and overcomes the slow response speed of the system when only software is used for intrusion detection. In system hardware detection, with FPGA as core, arranging various intrusion detection algorithms in FPGA for parallel running can improve the real time and reliability of the system.

The paper introduces a new type of biological drug transport box combined with the advantages of both with a low power consumption and low price. It explains the design of the appearance and space structure of the system, air flow cooling structure, and the hardware and software structure in the control part. Experiment results indicate that the solution put forward in the paper is simple and reliable, that the constant temperature effect is good and that the whole quality ratio of the transport box is high at a lower cost.
