 摘  要
 目前工業(yè)控制現(xiàn)場(chǎng)以有線網(wǎng)絡(luò)居多，但它們存在布線復(fù)雜、成本高等缺點(diǎn)。為此本論文設(shè)計(jì)了一個(gè)基于nRF401芯片的無(wú)線數(shù)據(jù)采集系統(tǒng)。該系統(tǒng)設(shè)置方便，不需布線即可采集多點(diǎn)的數(shù)據(jù)，因而成本低，克服了有線網(wǎng)絡(luò)存在的缺點(diǎn)。論文以采集溫度數(shù)據(jù)為例進(jìn)行了設(shè)計(jì)，給出了無(wú)線數(shù)據(jù)采集系統(tǒng)的硬件具體電路及通信協(xié)議的具體格式，上位機(jī)采用查詢的方式對(duì)多個(gè)測(cè)溫點(diǎn)進(jìn)行查詢。該系統(tǒng)具有數(shù)據(jù)傳輸速度快，可靠性高，功能易擴(kuò)展等特點(diǎn)，適用于多種工業(yè)領(lǐng)域。

Abstract
Nowadays, the majority of industrial field buses are lineate, so they are complicated and more cost. The paper designs a wireless data acquisition system based on the chip of nRF401. The system can be installed anywhere easily, and can acquisite the data of several different points at the same time. This low-cost system overcomes the shortcomings of the cable network. With the special case of temperature data collecting, the detailed hardware circuits of the wireless data acquisition system were designed in the paper. PC inquiries temperature data one time per second. The specific format of communication protocol is given. The system features quickly data transmition, more reliable, so it can be used in a variety of industrial fields.
