摘要: ZigBee技術(shù)是一種短距離、復(fù)雜度低、功耗低、傳播速率低、成本低的雙向無線通信技術(shù)。主要用于距離短、功耗低且傳輸速率不高的各種電子設(shè)備之間進(jìn)行數(shù)據(jù)傳輸以及典型的有周期性數(shù)據(jù)、間歇性數(shù)據(jù)和低反應(yīng)時(shí)間數(shù)據(jù)傳輸?shù)膽?yīng)用。
本文著重于介紹基于ZigBee的數(shù)據(jù)采集部分，選用ZigBee將終端傳感器收集的各種參數(shù)傳至網(wǎng)關(guān)，再采用有線形式將網(wǎng)關(guān)數(shù)據(jù)傳至地中央控制計(jì)算機(jī)，由計(jì)算機(jī)對(duì)數(shù)據(jù)進(jìn)行分析.
根據(jù)課題要求分析了系統(tǒng)設(shè)計(jì)的原則、性能要求，選擇CC2430作為本設(shè)計(jì)的主芯片，講述了無線數(shù)據(jù)采集性技術(shù)，并對(duì)液晶顯示器器進(jìn)行了比較,選用LCD1062液晶顯示器。根據(jù)方案，畫出了結(jié)構(gòu)框圖，繪制Protel原理圖，介紹電源電路,串口轉(zhuǎn)換電路,天線電路.根據(jù)設(shè)計(jì)要求，選擇IAR開發(fā)環(huán)境，介紹了其應(yīng)用步驟。

Based on the ZigBee wireless pressure measurement
Abstract: ZigBee technology is a kind of close, low complexity and low cost, low power consumption, low rate of two-way wireless communication technology. Is mainly used for short distance and low power consumption and transmission rate is not high to data transmission between various kinds of electronic equipment, as well as the typical periodic data, intermittent data and low response time data transmission applications.
This paper focuses on the part of data acquisition based on ZigBee, using ZigBee terminal sensors to collect all kinds of parameters to pass to the gateway, then using cable will be the gateway to transmit the data to the central control computer, analyze the data by computer.
According to project requirement analysis to the principles of system design, performance requirements, choose CC2430 as the design of main chip, tells the story of the wireless data acquisition technology, and compares the liquid crystal display device, choose LCD1062 LCDS. According to the scheme, draw the structure diagram, map Protel principle, introduces the power supply circuit, serial interface conversion circuit, the antenna circuit. According to the design requirements, choose the IAR development environment, the application steps are introduced.
Keywords: The wireless data acquisition ZigBee technology CC2430 LCD1062 IAR
