Design of Wireless Logging Instrument System for Monitoring Oil Drilling Platform

In order to achieve more effective monitoring and to solve the heavy workload issues of installation and removal on the existing wired-system logging site, thus guarantee the safety in normal operation, a wireless logging instrument system is designed to monitor the oil drilling platform. This paper introduces the overall architecture of the wireless system, and develops the hardware system - in which embedded software is designed - based on analog-digital conversion device, field-programmable gate array chip, and microprocessor. Combined with wireless sensor technology, analog measurements, and encoding quadruple frequency and phase-detection techniques, the wireless nodes in the system can detect and preprocess analog signals in the frequency range from 0.1 to 200 Hz and encoder signals of 90° phase difference, then output data through wireless transmitter module to upper monitoring center. Experimental results show that this system can realize a real-time wireless communication and monitoring for oil drilling platform stably. Moreover, it has features such as coding flexibility, high precision, good reliability, high integration, small size, and low-power consumption. Thus, the system provides a promising solution of data collection and analysis for the drilling platform.
