[Abstract]:Qualified nuclear fuel rods are the key factors to ensure the safe and stable operation of nuclear reactors. The 16-channel high-speed data acquisition card based on gigabit Ethernet is mainly used in the new non-destructive testing system of nuclear fuel rods. The data acquisition card is required to collect the count values of 16 input signals in a certain time range at the same time, and the counting timing range is 200 渭 s / s. Timing time and communication time are set by the host computer and the counting value is temporarily stored in the acquisition card. After satisfying the communication condition, the data is sent to the remote computer via Gigabit Ethernet. The operation control of the card is realized by sending instructions from the remote host computer via Gigabit Ethernet. In the design, 16 counters are realized by EP2C5T144FPGA chip to count 16 input signals and a 32-bit timer is used to control the counting time. SDRAM is used as data storage and ping-pong storage is used to temporarily store data. The S3C440BOX ARM chip is used as the core controller of the acquisition card, which is responsible for data transfer, counter control, reading and writing I / O, sending data and receiving commands, and controlling the coordinated operation of the data acquisition card. The communication between acquisition card and remote computer is realized by AX88180 Gigabit Ethernet controller and 88E1111 physical chip. In this paper, based on Visual Studio2010 integrated development environment and Microsoft basic class library (MFC), the application software of upper computer is developed with C language. The man-machine interface is designed to control the operation of data acquisition and the receiving of data. Through the field test, the data acquisition card designed in this paper has the advantages of high speed, low packet loss rate, stable network transmission and satisfying the design requirements.
