The author used MSComm to achieve the control of the uranium neutron logging instrument, and the real-time communication between the ground software system and the downhole detecting instrument through serial communication technology. Two problems were resolved intensively. Firstly, the real-time parameter control and feedback monitoring are implemented mainly through controlling the high voltage power supply and ion source to control the neutron flux, and utilizing the instrument feedback information to monitor the neutron source state. Secondly, the real-time data acquisition and display are achieved through the data acquisition module which monitors the instrument indirectly and ensures the instrument to work safely and stably. The reliability and practicability of the software system is verified by experiments.
