摘要
基于SoPC的节流控制系统为压井远程智能监控系统的一部分。该系统采用了在FPGA中加入NIOSII嵌入式软核CPU的SoPC技术,可实现压井过程中对多级节流管汇的控制。论述了液动平板阀和节流阀的控制原理,控制电路的设计方法和控制流程。该系统运行可靠,控制灵敏性高,与以往的控制系统相比,体积更小,功耗更低,具有较好的应用前景。
The throttle control system based on SoPC discussed in this paper is a part of the remote intelligent monitoring system for killing. SoPC technology is applied in the PPGA which adds NIOS II embedded soft-core CPU. This system can realize control of multi-stage throttle manifold in the killing. This article discusses the control principle of hydraulic throttle and flat valve, the design method of circuit and control flow. This system is reliable and sensitive. It is smaller and lower power compared with the previous system, and has good application prospects.
