摘要：目前，國內原油含水計量方面的在線儀表大都功能單一，現場適用范圍窄，適應能力差，其儀表準確度會受到現場諸多因素的影響，而且擴展性差，不便升級和更換部件，而油田進入中、高含水期采油階段對原油含水計量的要求也越來越高。本文簡單介紹了嵌入式系統的軟件和硬件的特點、應用、現狀及發展前景，闡述了嵌入式系統用在原油含水分析儀的設計中具有較好的適用性和優點。最后應用短波吸收原理，通過PC104采用模塊化設計，實現了用嵌入式系統來完成原油含水分析儀的硬件和人機界面設計。

Abstract：Currently, the on-line gauges of the crude oil contained water in calculate have simple functions and narrow application scope, and the orientation ability is bad, and its gauge accurate been influenced by many spot of factors, and its characteristic of expanding is bad, has the inconveniences for promoteing to higher grade and replaceing the parts, but the oil-field request calculate of crude oil contained water more and more high when crude oil contained water enters inside, high period. The article introduces the characteristics、application、present condition and development foregrounds of the software and hardware of the Embedded System and expatiates the good applicability and advantage of Embedded System in the design of the type system in analytic instrument of the crude oil contained water. Finally, combines the adoption short-wave absorbed principle and completes the hardware and human-machine interface design of the analytic instrument of the crude oil contained water used the Embedded System with PC104 adopted the mold piece turns the design.
