【摘要】：隨著電力線載波通信技術的發(fā)展,油田網絡的通信媒介可依賴于正在投入使用的電力線,可減少大量的人力和網絡鋪設所產生的費用,也方便后期的運維和管理。電網的結構導致電力線載波路由尋址算法在尋址過程中具有較強的盲目性,尋址結果的準確性不高,因此設計一種改進的尋址算法和適用于電力線載波通信的硬件系統(tǒng)十分重要。本文針對這幾個問題進行深入研究。首先,針對電力線載波網絡的時變性較強以及組網方式復雜的特點提出一種適用于電力線載波網絡的組網方式,分析了基于ACO的電力線載波路由尋址算法中尋址因子的盲目尋址以及過早陷入非最優(yōu)解的原因并在算法的全局更新規(guī)則和初始化能量值設定方面進行了改進優(yōu)化。其次,根據電力線載波通信噪聲強和衰減大的特點以及針對模擬監(jiān)測系統(tǒng)的需要,設計了電力線載波通信技術網絡中負責傳輸數據的電力線載波模塊、負責采集數據的傳感器模塊等設備,設計包括了模塊的硬件結構、電路設計原理圖與印刷電路板設計以及支持硬件正常工作的軟件結構設計,并根據上位機與傳感器節(jié)點之間的工作特點提出了一種穩(wěn)定的通信協(xié)議。最后,搭建了基于電力線載波組網的油田監(jiān)測電路系統(tǒng),設計了油田監(jiān)測與管理系統(tǒng)網頁,搭建了服務器后臺數據庫以減小數據冗余度和提高數據獨立性。在實驗室環(huán)境下對算法性能進行分析并且對硬件設備進行了測試,實驗結果表明整個系統(tǒng)在實驗室環(huán)境下達到預期效果。
[Abstract]:With the development of power line carrier communication technology, the communication medium of oil field network can rely on the power line being put into use, which can reduce the cost of large amount of manpower and network laying, and also facilitate the later operation and management. Because of the structure of power grid, the power line carrier routing algorithm is blind in the process of addressing, and the accuracy of the addressing result is not high. Therefore, it is very important to design an improved addressing algorithm and a hardware system suitable for power line carrier communication. This article carries on the thorough research to these several questions. First of all, in view of the characteristics of strong time-varying and complex networking mode of power line carrier network, a new method for power line carrier network is proposed. This paper analyzes the blind addressing of addressing factor and the reason of premature falling into non-optimal solution in the power line carrier routing addressing algorithm based on ACO, and improves and optimizes the global updating rule and initialization energy value of the algorithm. Secondly, according to the characteristics of strong noise and attenuation of power line carrier communication and the need of analog monitoring system, the power line carrier module in power line carrier communication network is designed, which is responsible for transmitting data. The design includes the hardware structure of the module, the circuit design schematic diagram and the printed circuit board design, as well as the software structure design to support the normal work of the hardware. A stable communication protocol is proposed according to the working characteristics of the upper computer and the sensor node. Finally, the oil field monitoring circuit system based on power line carrier network is built, the oil field monitoring and management system web page is designed, and the server backstage database is built to reduce the data redundancy and improve the data independence. The performance of the algorithm is analyzed in the laboratory environment and the hardware equipment is tested. The experimental results show that the whole system achieves the desired results in the laboratory environment.
