Application of distributed multi-channel real-time data acquisition and display system in civil aviation test

In modern industrial automatic measurement and control system, data acquisition and processing system is a very important link, so the existence of multi-channel data acquisition has a very important significance. This paper introduces the development and research significance of data acquisition, and elaborates a remote distributed multi-channel data acquisition system, which is divided into test terminal, server, client and three groups of networks. Realize on-site collection, dynamic reorganization of system functions, complete parallel collection of some data, and realize massive experimental data storage, dynamic real-time monitoring of data, playback and interception of collected data, and generate experimental data graph curves and print out functions. The interference to the data acquisition system can be eliminated by shielding, isolating and grounding the interference signals in the collected signals, and the efficiency and accuracy of the later data processing can be realized.
