本文从机械部件的设计安装、检测液位的光电转换电路和程序设计三个部分,提出了在按液位定时计量的单板机和单片机自动控制、检测容积泵流量以及发动机耗油量过程中,如何抑制影响系统可靠性的因素、事前提高系统各组成部分的固有可靠度和逐级清除不可靠隐患所采取的技术措施,稳定可靠地实现按液位定时计量的液流量检测自动化。
In this paper, the design and installation of mechanical components, the photoelectric conversion circuit to detect the liquid level and the program design are presented in this paper. The automatic control of the single-chip microcomputer and single-chip microcomputer that measures the liquid level timing is proposed to detect the displacement of the positive displacement pump and the fuel consumption of the engine , How to suppress the factors that affect system reliability, advance the inherent reliability of each component of the system, and remove the unreliable hidden dangers step by step by adopting technical measures to realize the fluid flow detection automation stably and reliably according to the timing of liquid level.
