【摘要】 本文扼要介绍了可编程控制器的设计方法,并以可编程只读存储器(EPROM)为核心,设计了一种新的井下数据采集和发送系统,使其较以前的井下系统有元器件数目少、可靠性高、功能灵活等优点,从而更加适合于井下高温高压、空间有限的环境。更多还原

【Abstract】 This paper introduces the brief design method of programmable contro-ller and a new data acquisition and transmission system around an EPROMaccording to the design method. This system has less components and ismore reliable and more flexible ihan previous one. So, it is suitable todownhole tools where the temperature is high and the space is limited.更多还原
