介紹了一種基于C8051F020單片機(jī)的多路壓力測量儀。該測量儀選用電阻應(yīng)變式壓力傳感器采集壓力信號(hào)，并經(jīng)放大電路處理后送入C8051F020單片機(jī)，再由C8051F020單片機(jī)內(nèi)部的A/D轉(zhuǎn)換器將采集到的壓力信號(hào)進(jìn)行模數(shù)轉(zhuǎn)化，然后分別對數(shù)據(jù)進(jìn)行存儲(chǔ)和顯示。該測量儀能測量6路壓力信號(hào)，并且各測量點(diǎn)都能單獨(dú)檢測和設(shè)置。由于采用了C8051F020單片機(jī)，簡化了硬件電路，增強(qiáng)了抗干擾能力，使得測量儀具有測量精度高，沖擊小等特點(diǎn)。
Abstract:
A measurement apparatus for multi-channel pressure based on single chip microcomputer is introduced.It can measure 6 channels signal of the pressure，and the pressure measure points can be detection and located individually.The pressure signal sampling is obtained by resistor stress-type pressure sensors，the digital signals of 6 channels are collected through amplifying and adjustment circuit of pressure signals and internal integrated A/D converter of MCU.Finally，and it realizes the function to store and display data separately.C8051F020 was used to made hardware circuit simple，and it also enhanced the anti-interference ability.It features high precision and little impact.
