The Key Technology Research Of Data Acquisition And Communication In DIS

This paper, network programming technique based on the SOCKET realized real-time data acquisition and off-line files transfer in DIS. The full name of DIS is the Digital Information System, it is a new generation of digital experimental teaching System. This paper first introduced the present situation of data acquisition and communication in the key technology of the realization in the DIS, and the significance of SOCKET network programming realize real-time data acquisition and offline file transfer. Analysis the overall framework in the key realization of data acquisition and communication technology and the circuit of the network communication, focusing on the program realization in the software of the next place machine and PC.The key technology of data collection and communication in DIS support real-time data collection and off-line files transmission and documents. A deep research SOCKET network programming technology principle and the TCP/IP protocol, a machine in the μc TCP/IP protocol stack on the basis of realized the client (the sending end) and server (receiver), PC in WinSock basis and realize the off-line files transfer and real-time data acquisition.At last, the paper show the collection effect of the whole system and the process to design the item.The application based on SOCKET network programming to DIS, can use network strings to realize establishing LAN based on Multi-DIS. Compared with the USB communication technology, the stability and high-speed data transmission of DIS and the technology of remote data acquisition and communication based on Multi-DIS have more advantages.
