【摘要】：白酒是传统固态发酵工艺的产物,我国有着几千年的发展历史。随着科技的进步,目前国内大型白酒企业基本实现了白酒勾储车间、自动灌装车间的信息化建设,但对固态发酵车间整体管理水平较低,停留在排产计划纸质化、发酵管理经验化、人员轮班程式化的初级阶段,这成为企业信息化管理的短板。基于ZigBee技术实现的无线传感器网络能够满足大量采集数据节点、低功耗要求的窖池发酵监测系统设计。ZigBee技术是一种近距离、低复杂度、低功耗、低成本、低速率的无线通信技术,工作频率在2.4GHz,传输距离为30～100米,主应用在低通信速率、短距离无线通信系统中。本文设计并实现的窖池发酵监测系统系统能够对车间各窖池参数自动采集,并在实时监测的基础上,监测数据经云端专家系统分析、处理、诊断,多终端全景展示发酵过程,并与车间温控制系统联动,形成对车间环境的闭环控制,提高窖池生产效率。本论文根据白酒酒窖发酵过程参数监测需求,采用有线和无线传输结合的方式,将采集终端节点数据发送到上位机服务系统分析处理。基于CC2530为控制芯片的数据采集终端系统,主要是由协调器、路由器和终端节点三种设备类型组成。终端节点定时从休眠状态醒来采集数据,并通过ZigBee无线通信网络上传到协调器,然后立刻进入休眠状态,将终端节点功耗降至最低;协调器存储终端节点的数据,并通过RS485总线上传到上位机。路由器起到网络中继功能,转发路由消息。硬件部分重点设计了终端节点功耗和传感器电路(包括温度传感器、PH传感器和酒精传感器电路)、协调器的RS485通讯接口、时钟与存储模块电路,以及三种设备的人机接口(包括LCD显示、按键和LED)。同时根据硬件电路设计,在应用程序中实现了对传感器数据有效采集、低功耗管理和数据传输等等功能。在ZigBee协议栈组网时,应用程序根据应用场合网络数量多、传输范围广、网间干扰强特点,设计了基于发酵车间的组网算法,有效的解决了不同车间以及同一个车间内不同网络的串扰问题。上位机采用工业组态软件,设计并实现了基于MODBUS通信协议上位机控制系统,通过RS485总线将协调器中存储的窖池数据成功读取,实现了对终端节点采集数据的收集与处理,并绘制了曲线以及数据存储等功能,根据分析结果反馈终端系统进行优化调控。文章最后对基于ZigBee技术实现的窖池发酵无线监测系统进行了验证。首先对ZigBee网络进行了组网测试,包括网络的稳定性、传输可靠性等;分别校准并测试传感器数据的测试结果,测量准确度以及终端节点的功耗都能达标;最后将该系统进行现场实地测试,结果表明该系统满足设计要求。同时说明了ZigBee无线通信网络技术在大量测量节点、低功耗以及网络稳定性等应用场合有很大优势。
[Abstract]:Liquor is the product of traditional solid-state fermentation technology, China has a history of thousands of years. With the progress of science and technology, at present, large liquor enterprises in China have basically realized the information construction of liquor hook-up workshop and automatic filling workshop, but the overall management level of solid-state fermentation workshop is relatively low, and they stay in the paperization of production scheduling plan. Fermentation management experience, personnel shift formulaic primary stage, this becomes the short board of enterprise information management. Wireless sensor network based on ZigBee technology can meet a large number of data nodes. The design of cellar fermentation monitoring system with low power consumption. ZigBee technology is a kind of short distance, low complexity, low power consumption, low cost. A low rate wireless communication technology with a working frequency of 2.4 GHz and a transmission distance of 30 ~ 100m. It is mainly used in low-rate, short-range wireless communication systems. The cellar fermentation monitoring system designed and implemented in this paper can automatically collect the parameters of each cellar in the workshop, and on the basis of real-time monitoring, the monitoring data can be analyzed, processed, diagnosed and displayed by multi-terminal panoramic fermentation process through cloud expert system. Combined with the workshop temperature control system, closed-loop control of workshop environment is formed to improve the production efficiency of the cellar. According to the requirement of monitoring the fermentation process parameters of liquor cellar, the data of the terminal node was transmitted to the upper computer for analysis and processing by combining wired and wireless transmission. The data acquisition terminal system based on CC2530 is mainly composed of three kinds of equipment types: coordinator router and terminal node. The terminal node periodically wakes up data from the dormant state, uploads it to the coordinator through the ZigBee wireless communication network, then immediately enters the dormant state to minimize the power consumption of the terminal node; the coordinator stores the data of the terminal node. And the RS485 bus upload to the host computer. Routers play a network relay function, forwarding routing messages. In the hardware part, the terminal node power consumption and sensor circuit (including temperature sensor, PH sensor and alcohol sensor circuit, RS485 communication interface of coordinator, clock and memory module circuit) are designed. And three kinds of device man-machine interface (including LCD display, keystroke and LEDX. At the same time, according to the design of hardware circuit, the functions of effective collection of sensor data, low power management and data transmission are realized in the application program. When the ZigBee protocol stack is set up, the application program designs the networking algorithm based on fermenting workshop according to the characteristics of large number of applications, wide transmission range and strong internetwork interference. It effectively solves the crosstalk problem of different networks in different workshops and the same workshop. The upper computer uses industrial configuration software to design and implement the host computer control system based on MODBUS communication protocol. The hoard data stored in the coordinator is read successfully through the RS485 bus, and the collection and processing of the terminal node data are realized. The functions of curve and data storage are drawn, and the terminal system is optimized according to the result of analysis. Finally, the wireless monitoring system of cellar fermentation based on ZigBee technology is verified. Firstly, the ZigBee network is tested, including the network stability, transmission reliability and so on, the test results of sensor data are calibrated and tested, the accuracy of measurement and the power consumption of terminal nodes are up to standard. Finally, the system is tested on the spot, and the results show that the system meets the design requirements. At the same time, the ZigBee wireless communication network technology has great advantages in a large number of measurement nodes, low power consumption, network stability and other applications.
