【摘要】 现有的白酒固态发酵基本采用封闭式发酵，无法得到发酵窖池内酒精浓度的实时数据，为了解决此问题，提出一种基于无线传感器网络的固态窖池发酵酒精浓度监测系统设计。该系统以CC2530为主控芯片，采用ZigBee技术设计无线传感器网络，采用基于ModBus协议的RS485总线设计有线传输方式，采用TGS2620酒精传感器采集窖池内酒精浓度数据，将通过滤波、拟合处理的数据以无线传输和有线传输结合的方式上传至上位机，上位机对数据进行实时显示。系统具有自动采集数据、自动传输数据、自动显示数据的特点，测试结果表明，该系统运行稳定，数据可靠，满足设计要求。更多还原

【Abstract】 The existing Baijiu solid-state fermentation process is basically closed fermentation. The realtime data of alcohol concentration in fermentation cellar can not be obtained. In order to solve this problem,a monitoring system of alcohol concentration in solid-state pit fermentation based on wireless sensor network is proposed. The system takes CC2530 as the main control chip,uses ZigBee technology to design the wireless sensor network,uses RS485 bus based on ModBus protocol to design the wired transmission mode,uses TGS2620 alcohol sensor to collect the alcohol concentration data in the pit,and uploads the filtered and fitted data to the host computer through the combination of wireless transmission and wired transmission. The upper computer displays the data in real time. The system has the characteristics of automatic data collection,automatic data transmission and automatic data display. The test results show that the system runs stably,the data is reliable and meets the design requirements.更多还原
