Design of underground elevation drilling logging system

For problems of low bus utilization and low data transfer rate and so on existed in traditional logging system, a design scheme of underground elevation drilling logging system was proposed, and the system structure, network topology, and design of hardware and software of the probe node with PIC18LF4680 as core were described. The system uses file management control chip for data management, achieves two logging ways of having cable and non-cable. The practical application shows that the system is stable and is applicable for measurement of mine production conditions.
