摘要气体微流量检测装置是一种被广泛应用于工业中用来测量气体泄露的必备设备。这种仪表可以显示气体通过的流量，让使用者直观的检测气体流量的数值以判断是否发生气体泄露。
气体微流量检测装置，一般由传感器，单片机和显示装置构成，通过传感器接受模拟信号，之后由单片机转化为数字信号在显示装置中显示数据。相对于以前应用的老式气体微流量装置，单片机构成的气体微流量检测装置可以更灵敏的和精确的测量气体的微流量数值，对现代社会的工业化生产有着重要的价值。本文介绍的就是基于MP430F2的气体微流量检测装置设计。
本文完成了基于MP430F2的气体微流量检测装置的设计和运行，实现了充分利用硬件资源，将传感器发出的模拟信号转化成数字信号并显示的目的。软件硬件设计互相结合，整个系统具有可靠，方便的优点。成品对基于单片机的气体微流量装置设计领域有一定的参考价值。84606

Abstract Gas micro flow measurement device is a kind of necessary equipment which is widely used in industry to measure the gas leakage。 Gas micro flow detection device displays the flow of gas through, and it allows the user to visually detect the value of the gas flow to determine whether gas leakage occurs。
The device is composed of a sensor, a single chip microcomputer and a display device。 It received analog signals through the sensor。Then, the device will convert to digital signals through the microcontroller and display the data in the display device。 Compared with the previous application of the old-fashioned gas micro flow device, the new Gas micro flow measurement device which composed of the single-chip microcomputer will be more sensitive and precision measurement the micro flow of gas,which has an important value to the industrialized production of the modern society。 This paper introduces the design of gas micro flow measurement device which based on MP430F2。
In this paper, the design and operation of the gas micro flow measurement device which based on MP430F2 is completed。The device make the most of hardware resources。 The device accurately transforms the signal from the sensor and display it。 The software and hardware are combined with each other。The whole system is very reliable and convenient。 It has a certain reference value for the design of the gas micro flow device which based on MCU。
