Abstract

Surface controller is a very important part of logging system, Mainly complete logging signal processing and transmission, Logging signal processing mainly refers to decoding and processing the uploaded encoded logging signal, Signal transmission refers to uploading original logging data to the software of the supreme computer and receiving and issuing commands through CAN bus and Ethernet, A surface controller is used to monitor downhole production conditions in real time. In this paper, the surface controller is divided into two modules of logging signal decoding and transmission to illustrate the working principle of the controller. The whole system takes STM series embedded chip as the core to build peripheral circuit, The decoding module takes STM103 as the core processing unit, plus the signal conditioning circuit, The transmission module takes STM429 as the core processing unit, Peripheral circuits are mainly memory chips, CAN buses, Ethernet circuit and so on, Complete the signal packaging and upload to the top computer for data processing.

基于STM系列测井的地面控制器应用研究

地面控制器是测井系统的重要组成部分，主要完成测井信号的处理和传输，测井信号处理主要是对上传的编码测井信号进行解码和处理，信号传输是指将原始测井数据上传到上位机软件中，并通过CAN总线和以太网接收和发出命令，地面控制器用于实时监控井下生产情况。本文将地面控制器分为测井信号解码和传输两个模块来说明控制器的工作原理。整个系统以STM系列嵌入式芯片为核心构建外围电路，解码模块以STM103为核心处理单元，加上信号调理电路，传输模块以STM429为核心处理单元，外围电路主要有存储芯片、CAN总线、以太网电路等，完成信号封装并上传到上位机进行数据处理。
