【摘要】：由于工業(yè)的不斷進步,環(huán)境污染日趨嚴重,已阻礙了國家推進綠色生態(tài)發(fā)展進程和影響到國家經(jīng)濟基礎建設。尤其是水污染現(xiàn)象日益突出,已引起社會各界廣泛關注,演變?yōu)樯鐣惹薪鉀Q的問題,改善水質刻不容緩。當前水環(huán)境質量很難滿足人類的需求,因此,對于水質實時在線監(jiān)測系統(tǒng)的研究就很有必要性。本文提出了一種新型的基于物聯(lián)網(wǎng)的水質實時在線監(jiān)測系統(tǒng)方案。通過對當前水質實時在線系統(tǒng)現(xiàn)狀進行理論分析,結合傳感器應用、單片機發(fā)展、無線數(shù)據(jù)通信和C#應用軟件及數(shù)據(jù)庫軟件設計的應用理論。針對當前水域檢測現(xiàn)狀存在的問題,該方案優(yōu)點有:(1)基站實時監(jiān)測水質數(shù)據(jù),采集數(shù)據(jù)精度高,可長時間穩(wěn)定在線運行;(2)通過TCP/IP(Transmission Control Protocol/Internet Protocol)可靠連接上傳至服務器端,服務器接收軟件精確的數(shù)據(jù)解析利于對數(shù)據(jù)操作處理;(3)結合清潔的太陽能供電方式,擺脫了有線供電、有線供網(wǎng)的種種不便;(4)具備體積小和性價比高等特點,同時后期可做擴展模塊對于水質成分元素進行分析。本論文研究工作如下:整個系統(tǒng)分成三個部分:下位機終端采集系統(tǒng)、數(shù)據(jù)傳輸通信系統(tǒng)以及上位機管理平臺。首先,設計了下位機基于STM32F103C8T6單片機對傳感器數(shù)據(jù)采集系統(tǒng)。下位機是基于STM32設計結合傳感器工作原理,檢測輸出信號形式,選擇相應的數(shù)據(jù)處理方式以利于計算機采集處理,由STM32作為控制系統(tǒng)承擔傳感器采集數(shù)據(jù),利用其內置豐富強大接口資源和片上集成外設,可快速響應并進行數(shù)據(jù)處理,通過液晶顯示屏顯示當前實時監(jiān)測值,同時將數(shù)值輸出至GPRS(General Packet Radio Service)模塊,使基站系統(tǒng)對傳感器的采集參數(shù)在線上傳。其次,研究GPRS無線傳輸通信系統(tǒng)工作原理。無線網(wǎng)絡傳輸系統(tǒng)是單片機向串口輸出數(shù)據(jù)至與單片機相連的GPRS模塊串口端,利用TCP/IP無線網(wǎng)絡傳輸協(xié)議向中心數(shù)據(jù)管理系統(tǒng)實時上傳數(shù)據(jù),保證上位機和下位機實時連接。最后,設計了基于C#結合SQL軟件開發(fā)的中心管理系統(tǒng)。通過C#軟件編程和界面設計結合數(shù)據(jù)庫后臺數(shù)據(jù)支撐而開發(fā)的一套完整管理平臺系統(tǒng),由于SQL Server具有強大的數(shù)據(jù)處理能力,結合C#簡潔的窗體設計而開發(fā)的操作管理平臺。實驗證明,該系統(tǒng)具有很好的設計效果,具有實際應用價值,做到水質有問題早發(fā)現(xiàn)早解決,防止進一步擴散擴大,提高科學高效的監(jiān)測管理效率。通過監(jiān)測水質參數(shù)衡量水域環(huán)境優(yōu)劣,為相關部門提供應對決策與管理的措施,具有重要的指導意義。
[Abstract]:Due to the continuous progress of the industry, the environmental pollution is becoming more serious, has hindered the country to promote the development of green ecological process and the influence to the national economic infrastructure. Especially water pollution have become increasingly prominent, has aroused widespread concern in the community, the evolution of social urgent problems, improve the quality of the water quality of the environment without delay. It is difficult to meet the human therefore, the research on demand, real-time online monitoring system of water quality is very necessary. This paper presents a new type of IOT based water quality real-time online monitoring system. Through the theoretical analysis on the current situation of water quality on-line system, combined with the sensor applications, MCU development, application of the theory and application of C# wireless data communication software and database software design. According to the existing situation of water detection problems, the advantages are: (1) the number of base station real-time monitoring of water quality According to the data acquisition, high precision, stable for long time online operation; (2) by TCP/IP (Transmission Control Protocol/Internet Protocol) reliable connection upload to the server, the server receives the accurate data analysis software for data processing; (3) combining solar power clean, get rid of the power supply cable, cable inconvenience for the network; (4) with small volume and high cost performance, and can be extended for late module water quality component elements are analyzed. The research work of this paper is as follows: the whole system is divided into three parts: terminal acquisition system, data communication system and PC management platform. Firstly, the design of PC and STM32F103C8T6 chip microcomputer the sensor data acquisition system based on MCU is STM32. Combined with the design principle of the sensor based on detection of the output signal, select the appropriate number According to the processing mode for computer acquisition and processing, by STM32 as the control system for sensor data collection, using its built-in rich interface resources and powerful on-chip peripherals, rapid response and data processing, through the LCD screen display the current value of real-time monitoring, while the numerical output to GPRS (General Packet Radio Service) module, the base station system for sensor online upload the collected parameters. Secondly, the working principle of GPRS wireless communication system. The wireless network transmission system is a single chip to the serial output data to the GPRS module connected with the singlechip serial port, using TCP/IP protocol of wireless network to upload real-time data center data management system, to ensure the upper and lower machine in real time the design of C# connection. Finally, combined with the center management system based on the SQL software. Through C# software programming and interface design. The combination of database background data support and the development of a complete set of management system, because the SQL Server has a powerful data processing capability, operation management platform with simple form design and the development of C#. The experimental results show that the system has good design effect, has practical application value, do early detection and solve water quality problems. To prevent the further spread of expansion, improve the scientific and efficient management efficiency. Through monitoring water quality parameters monitoring measure of water environment quality, provide decision-making and management measures for the relevant departments, has an important guiding significance.
