real strong, high data rate, data volume, plex, large amount of putation. This topic using LabView development platform design a can of multi channel running LAN remote data acquisition system, to realize the remote realtime data acquisition, display and database storage transmission and WEB publishing. Asked to plete system needs analysis, function moduledivides, flowchart design, each application of each module in specific code realization all process. The process is: through the data acquisition card and PC, sensor constitute a system acquisition corresponding externality ceases, will the data in the database, the paper takes Access by constructing LabWindows/CVI realize data file database dynamic storage and update, finally through LabVIEW software platform, realize the data processing, transmission and release. Software functions include: data acquisition, data query, data processing and data transmission and WEB publishing. Operation shows that realize the basic functions, and is expected to reach. This system has simple structure, strong monality, stable and reliable, good realtime, use agile, low cost advantages, and has strong expansion ability, for remote data acquisition, remote measurement and control, and other fields, have higher use value.
