【摘要】：隨著國內(nèi)城市化進(jìn)程的持續(xù)加快,城鎮(zhèn)污水排放量也正以驚人的速度在逐年攀升,這使得污水處理系統(tǒng)的擴(kuò)展迫在眉睫。目前國內(nèi)絕大多數(shù)的污水處理控制系統(tǒng)都建立在現(xiàn)場總線和工業(yè)以太網(wǎng)的基礎(chǔ)上,在新增設(shè)備時(shí)都需要重新敷設(shè)電纜,施工難度大且施工周期長。鑒于此,本文提出采用無線通信技術(shù)來解決新增設(shè)備的接入問題。在對常見幾種無線通信技術(shù)進(jìn)行研究與分析后,本文首先確定以ZigBee網(wǎng)絡(luò)作為擴(kuò)展系統(tǒng)的數(shù)據(jù)傳輸通道,然后在對曝氣生物濾池污水處理工藝與傳統(tǒng)污水處理系統(tǒng)結(jié)構(gòu)分析的基礎(chǔ)上,制定了系統(tǒng)的無線通信技術(shù)方案。論文的研究內(nèi)容包括新增設(shè)備的數(shù)據(jù)采集、ZigBee通信網(wǎng)絡(luò)的構(gòu)建及上位機(jī)監(jiān)控系統(tǒng)設(shè)計(jì)。根據(jù)污水處理現(xiàn)場干擾狀況與成本考量,本文選用單片機(jī)與模數(shù)轉(zhuǎn)換芯片作為數(shù)據(jù)采集器件。通信網(wǎng)絡(luò)構(gòu)建方面,本文采用順舟SZ05模塊和順舟SZ02模塊作為網(wǎng)絡(luò)設(shè)備的數(shù)據(jù)收發(fā)器,從而實(shí)現(xiàn)控制中心與現(xiàn)場的雙向數(shù)據(jù)交換。此外,本文還利用工控組態(tài)軟件對上位機(jī)監(jiān)控系統(tǒng)進(jìn)行了設(shè)計(jì)。在整體設(shè)計(jì)方案的基礎(chǔ)上,本文分別從硬件層面和軟件層面對污水處理無線通信系統(tǒng)設(shè)計(jì)方案進(jìn)行詳細(xì)地闡述并且對上位機(jī)監(jiān)控系統(tǒng)的設(shè)計(jì)過程也展開具體介紹。最后,本文通過搭建的系統(tǒng)調(diào)試平臺進(jìn)行了相關(guān)數(shù)據(jù)的傳輸實(shí)驗(yàn),進(jìn)而驗(yàn)證了系統(tǒng)方案的可行性與實(shí)用性。本文的研究創(chuàng)新點(diǎn)在于:利用ZigBee技術(shù)在污水處理現(xiàn)場搭建了一個(gè)結(jié)構(gòu)簡單、穩(wěn)定可靠的無線數(shù)據(jù)傳輸系統(tǒng),該系統(tǒng)可有效地解決現(xiàn)有污水處理系統(tǒng)的設(shè)備擴(kuò)展問題,進(jìn)而節(jié)約投資并提高污水處理系統(tǒng)的工作效率。
[Abstract]:With the continuous acceleration of urbanization in China, urban sewage discharge is increasing year by year, which makes the expansion of sewage treatment system imminent. At present, most of the domestic sewage treatment control systems are based on the field bus and industrial Ethernet. When the equipment is added, the cable needs to be re-laid, so the construction is difficult and the construction period is long. In view of this, this paper proposes to use wireless communication technology to solve the problem of access to new devices. After the research and analysis of several common wireless communication technologies, this paper first determines that the ZigBee network is used as the data transmission channel of the extended system. Based on the analysis of biological aerated filter wastewater treatment process and the structure of traditional sewage treatment system, the wireless communication technology scheme of the system is developed. The research contents of this paper include the construction of ZigBee communication network and the design of monitoring system. According to the interference situation and cost consideration of sewage treatment site, this paper chooses single chip computer and A / D conversion chip as data acquisition device. In the aspect of communication network construction, this paper adopts SZ05 module and SZ02 module as the data transceiver of the network equipment, thus realizing the two-way data exchange between the control center and the field. In addition, this paper also uses industrial control configuration software to design the upper computer monitoring system. On the basis of the overall design scheme, the design scheme of wireless communication system for sewage treatment is described in detail from the hardware level and the software level, and the design process of the upper computer monitoring system is also introduced in detail. Finally, the system debugging platform is used to carry out the data transmission experiment, and the feasibility and practicability of the system scheme are verified. The research innovation of this paper lies in: using ZigBee technology to set up a simple, stable and reliable wireless data transmission system in sewage treatment site, this system can effectively solve the problem of equipment expansion of the existing sewage treatment system. Then the investment is saved and the working efficiency of sewage treatment system is improved.
