以溫濕度采集監控為例,提出基于ZigBee和LabView的無線多點糧庫溫濕度監測系統。以CC2530為主要控制芯片,DHT11為溫濕度傳感器,采用ZigBee無線網絡協議

摘要:糧食是關系到國計民生的重要戰略物資,因此糧食的存儲將是至關重要的問題,研究如何科學有效的儲糧具有很大的社會價值和經濟價值。而溫度、濕度、氣體(二氧化碳、氧氣)濃度等對糧食存儲時間具有重大影響。由于糧庫容積較大,以上參數往往是具有空間分布的,需要布設多組傳感器才能準確獲取環境信息。本設計以溫濕度采集監控為例,提出基于ZigBee和LabView的無線多點糧庫溫濕度監測系統。以CC2530為主要控制芯片,DHT11為溫濕度傳感器,采用ZigBee無線網絡協議,通過建立星型網絡實現主從節點之間的數據采集和傳輸,最后利用串口與上位機PC端進行通信連接,并通過LabView開發平臺編程實現對采集到的數據進行顯示與處理,從而有效的實現如下功能:1、可在線實時地連續采集和記錄監測點位的溫度、濕度參數情況,并支持數據存儲和歷史記錄查詢,監測點位可擴充多達上萬個點; 2、可設定各監控節點位的溫濕度報警限值,當出現被監控的節點位環境參數異常時可自動發出報警信號,報警信息可發送本地及抄送遠程監測,系統可在不同的時刻通知不同的值班人員。實驗測試表明,該無線多點糧庫溫濕度采集系統能夠穩定可靠的運行,并具有組網簡單、造價低、維護性好等優點。35688

Abstract: Grain is a vital important strategic materials, grain storage is one of the important subjects related to national economy and people's livelihood, the science and the problem of grain storage have larger social value and economic value.The temperature, humidity, gas (carbon dioxide, oxygen) concentration has significant effects on  grain preservation time, etc.Due to the grain volume is larger, the above parameters is often has the spatial distribution, need to deploy more groups of sensors to get accurate information environment.The design temperature and humidity acquisition monitor, for example, based on LabView and ZigBee wireless multi-point grain depot temperature and humidity monitoring system.CC2530 as main control chip, DHT11 temperature and humidity sensor, using ZigBee agreement, through master-slave node between the star network data acquisition and transmission, finally communicate with PC using the serial communication technology, and through the LabView programming language implementation of the collected data for display and processing, thus effectively realize the following functions:.1, can online real-time continuous acquisition and recording monitoring points of the parameters of temperature, humidity, and support the historical record data storage and query, monitoring points can be extended up to tens of thousands of points;2, to set the alarm limit of monitoring point temperature and humidity, when there are abnormal monitoring point data can be automatically send out alarm signal, alarm information can send local and remote monitoring, the system can be in different time inform the personnel on duty.Experimental tests show that the wireless multi-point granary temperature and humidity acquisition system can run stable and reliable, and it has a simple network, less cost, good maintainability, etc.
