【摘要】：白酒是傳統(tǒng)固態(tài)發(fā)酵工藝的產(chǎn)物,我國有著幾千年的發(fā)展歷史。隨著科技的進步,目前國內(nèi)大型白酒企業(yè)基本實現(xiàn)了白酒勾儲車間、自動灌裝車間的信息化建設,但對固態(tài)發(fā)酵車間整體管理水平較低,停留在排產(chǎn)計劃紙質(zhì)化、發(fā)酵管理經(jīng)驗化、人員輪班程式化的初級階段,這成為企業(yè)信息化管理的短板。基于ZigBee技術實現(xiàn)的無線傳感器網(wǎng)絡能夠滿足大量采集數(shù)據(jù)節(jié)點、低功耗要求的窖池發(fā)酵監(jiān)測系統(tǒng)設計。ZigBee技術是一種近距離、低復雜度、低功耗、低成本、低速率的無線通信技術,工作頻率在2.4GHz,傳輸距離為30～100米,主應用在低通信速率、短距離無線通信系統(tǒng)中。本文設計并實現(xiàn)的窖池發(fā)酵監(jiān)測系統(tǒng)系統(tǒng)能夠?qū)囬g各窖池參數(shù)自動采集,并在實時監(jiān)測的基礎上,監(jiān)測數(shù)據(jù)經(jīng)云端專家系統(tǒng)分析、處理、診斷,多終端全景展示發(fā)酵過程,并與車間溫控制系統(tǒng)聯(lián)動,形成對車間環(huán)境的閉環(huán)控制,提高窖池生產(chǎn)效率。本論文根據(jù)白酒酒窖發(fā)酵過程參數(shù)監(jiān)測需求,采用有線和無線傳輸結(jié)合的方式,將采集終端節(jié)點數(shù)據(jù)發(fā)送到上位機服務系統(tǒng)分析處理。基于CC2530為控制芯片的數(shù)據(jù)采集終端系統(tǒng),主要是由協(xié)調(diào)器、路由器和終端節(jié)點三種設備類型組成。終端節(jié)點定時從休眠狀態(tài)醒來采集數(shù)據(jù),并通過ZigBee無線通信網(wǎng)絡上傳到協(xié)調(diào)器,然后立刻進入休眠狀態(tài),將終端節(jié)點功耗降至最低;協(xié)調(diào)器存儲終端節(jié)點的數(shù)據(jù),并通過RS485總線上傳到上位機。路由器起到網(wǎng)絡中繼功能,轉(zhuǎn)發(fā)路由消息。硬件部分重點設計了終端節(jié)點功耗和傳感器電路(包括溫度傳感器、PH傳感器和酒精傳感器電路)、協(xié)調(diào)器的RS485通訊接口、時鐘與存儲模塊電路,以及三種設備的人機接口(包括LCD顯示、按鍵和LED)。同時根據(jù)硬件電路設計,在應用程序中實現(xiàn)了對傳感器數(shù)據(jù)有效采集、低功耗管理和數(shù)據(jù)傳輸?shù)鹊裙δ�。在ZigBee協(xié)議棧組網(wǎng)時,應用程序根據(jù)應用場合網(wǎng)絡數(shù)量多、傳輸范圍廣、網(wǎng)間干擾強特點,設計了基于發(fā)酵車間的組網(wǎng)算法,有效的解決了不同車間以及同一個車間內(nèi)不同網(wǎng)絡的串擾問題。上位機采用工業(yè)組態(tài)軟件,設計并實現(xiàn)了基于MODBUS通信協(xié)議上位機控制系統(tǒng),通過RS485總線將協(xié)調(diào)器中存儲的窖池數(shù)據(jù)成功讀取,實現(xiàn)了對終端節(jié)點采集數(shù)據(jù)的收集與處理,并繪制了曲線以及數(shù)據(jù)存儲等功能,根據(jù)分析結(jié)果反饋終端系統(tǒng)進行優(yōu)化調(diào)控。文章最后對基于ZigBee技術實現(xiàn)的窖池發(fā)酵無線監(jiān)測系統(tǒng)進行了驗證。首先對ZigBee網(wǎng)絡進行了組網(wǎng)測試,包括網(wǎng)絡的穩(wěn)定性、傳輸可靠性等;分別校準并測試傳感器數(shù)據(jù)的測試結(jié)果,測量準確度以及終端節(jié)點的功耗都能達標;最后將該系統(tǒng)進行現(xiàn)場實地測試,結(jié)果表明該系統(tǒng)滿足設計要求。同時說明了ZigBee無線通信網(wǎng)絡技術在大量測量節(jié)點、低功耗以及網(wǎng)絡穩(wěn)定性等應用場合有很大優(yōu)勢。
[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.
