Safety inspection system with embedded Ethernet transmission based on SOPC

Abstract

The invention relates to a safety inspection system with embedded Ethernet transmission based on a SOPC. The input end of a data acquisition / conversion module of the system is connected with the output end of a X-ray detection plate, the output end of the data acquisition / conversion module is connected with the input end of a technical control and information receiving and processing system based on the SOPC, and the output end of the technical control and information receiving and processing system based on the SOPC is connected with an image data receiving and image processing module of a remote upper computer. In the system, various required modules are articulated on an AVALON bus by adopting the SOPC technology, the flexibility of the system is enhanced, the acquisition and transmission acceleration of the safety inspection system is achieved through hardware acceleration, and the stability of the system is improved; communication devices and communication lines do not need to be additionally arranged for realizing PCI or USB remote transmission of large-scale data; the Ethernet transmission is designed into embedded transmission; and rapid Ethernet transmission is realized by clipping the Ethernet communication protocol, thereby achieving high-speed transmission of large-scale data.

Description

technical field [0001] The invention relates to a security inspection system with Ethernet transmission based on SOPC (System-on-a-Programmable-Chip, ie System-on-a-Programmable-Chip), which belongs to the field of security protection. Background technique [0002] In the existing baggage security inspection system, it is common practice to use FPGA (Field-Programmable Gate Array) for pre-processing, and then to process data through DSP (Digital Signal Processing). FPGA+ARM (A general term for a class of microprocessors) and other implementations of baggage security inspection systems are also very common, and the effect is also very good. However, the system is not flexible enough, the tailorability is poor, the peripheral circuit is complicated, the upgrade is difficult, and the stability and reliability cannot be greatly improved. Because the traditional baggage security inspection transmission system generally uses ISA, PCI, and USB, the wiring is complicated, and in so...
