Upper computer software design for fretting signal acquisition system based on Qt

Abstract

Micro motion detection is an essential research direction in urban underground space and energy prospection. Aiming at the shortcomings of the traditional system for seismic exploration, the upper computer software of the micro motion signal acquisition system based on TCP/IP protocol is designed, which can be distributed offline acquisition and control. By formulating the communication protocol of the application layer and adding the heartbeat packet mechanism, the stable connection with the collector, data transmission and status monitoring is realized. Meanwhile the received data are stored and visualized, and the project management and task configuration are implemented by using the file reading and writing function of QT to achieve the effect of offline control. Through the test, the results show that each function can get the rapid and correct response of the lower computer, and the upper computer software of the system meets the design requirements. It has the advantages of high acquisition efficiency, reliability and convenience which has strong practicability.
