摘要
傳感器是通信和控制系統(tǒng)的最前端，在現(xiàn)在高速智能化的趨勢(shì)下，如何采集各種信號(hào)成了首當(dāng)其沖的問(wèn)題，而在大多數(shù)應(yīng)用場(chǎng)合要求在同一時(shí)間進(jìn)行多種數(shù)據(jù)的采集，現(xiàn)在的大部分單一的應(yīng)用系統(tǒng)不能滿足這樣的需求。
為了應(yīng)對(duì)這種情況，本文償試應(yīng)用多種傳感器集于一體進(jìn)行設(shè)計(jì)，應(yīng)用MCS—51單片機(jī)作為控制系統(tǒng)的核心，對(duì)多種數(shù)據(jù)進(jìn)行采集和顯示，由傳感器接入ADC0809到51單片機(jī)通過(guò)74LS164驅(qū)動(dòng)數(shù)碼顯示，在不增加控制芯片的情況下達(dá)到更多數(shù)據(jù)采集的目的，在現(xiàn)在的各種工程應(yīng)用中具有很大的實(shí)用價(jià)值。

ABSTRACT
Sensor is a communication and control system forefront, in the present trend of high-speed intelligent, how to collect all kinds of signals have become the first to problem to solve, In most applications , different kinds of signals must be collected at the same time, and now the big part of a single application system can not meet this demand.
In response to this situation, this article try to design with a variety of sensors set in one application, use the MCS-51 microcontroller as the core of the control system, a wide range of data acquisition and display, the signals collected by the sensors access to the 51 single-chip ADC0809 driven by 74LS164 digital display chip without increasing the control cost, but achieve the purpose of collecting more data. this system has great practical value in the present variety of engineering applications.）
