Design and Implementation of Fuel Tank Monitoring System Based on MSP430 Single Chip Microcomputer

对于汽车等机动车来说,油箱内保持充足的燃料,是其正常行驶的前提。机动车油箱液位的高度监测,能够更好地帮助驾驶员掌握机动车当前燃料情况,使行驶更加高效。本文提出基于MSP430单片机的油箱液位监测系统设计与实现,使得监测油箱液位更为简单直观,方便驾驶员对油箱液位情况实时掌握。所设计的系统创新性使用超声波探头以及单片机控制,超声波探头利用声波回传原理实现精准测量液位高度,利用单片机可在液位到达警戒值时实现报警功能,搭配Windows平台下的上位机软件,可以绘制实时液位变化的连续曲线并进行相关参数设置与显示。

For automobiles and other motor vehicles, keeping sufficient fuel in the fuel tank is the premise of their normal driving. The height monitoring of the fuel tank level of the motor vehicle can better help the driver to grasp the current fuel situation of the motor vehicle and make the driving more efficient. This paper presents the design and implementation of the oil tank liquid level monitoring system based on MSP430 single-chip microcomputer, which makes it more simple and intuitive for the driver to grasp the oil tank liquid level in real time. The designed system is innovatively controlled by ultra-sonic probe and single-chip microcomputer. Ultrasonic probe uses the principle of acoustic return to realize accurate measurement of liquid level height. Single-chip microcomputer can realize the alarm function when the liquid level reaches the warning value. With the upper computer software under the Windows platform, it can draw the continuous curve of real-time liquid level change and set and display the relevant parameters.
