Design of an intelligent downhole data monitoring system software based on Qt
Monitoring of downhole temperature,pressure,water cut,and other parameters plays a crucial role in enhancing oil extraction efficiency.After real-time measurement data is transmitted to the surface via fiber-optic technology,an intelligent down-hole data monitoring system software was developed based on Qt's cross-platform capabilities,on the foundation of signal prepro-cessing by the surface receiver.The software thread-processes the serial communication and data processing modules,employs a CRC-based Viterbi decoding algorithm to accurately decode the data,and then stores,displays,and alerts on the decoded data us-ing a database.Finally,it controls the GPRS module for remote and cloud storage of data using AT commands and the Modbus pro-tocol.This software is easy to maintain and port,and holds significant application value.
