基于TMS570和FreeRTOS的井下多参数记录仪
Downhole Multi-parametric Recorder Design Based on TMS570 and FreeRTOS
摘要
Abstract
In order to get the record downhole measurement parameters with long time ,low power and high reliability ,the TMS570 safe-ty critical microcontroller is selected to increase system reliability ,at the same time ,a measuring device with the appropriate digital inter-face is selected to make full use of its resources .After analyzing acquisition processes of every parameter ,a unique parameter survey mod-el is built ,three tasks such as parameter measurement ,parameter preservation and serial communication are realized under FreeRTOS real-time operating system and idle hook function is used to enter low-power mode .The underground multi-parameter recorder and the BlackBox of NOV have similar functions and indicators ,which can be used to improve drilling efficiency and optimize drilling perform -ance .关键词
