【摘要】:隨著我國城市化水平的不斷提高,城市的路燈照明系統(tǒng)不斷擴大,然而,由于惡劣天氣情況的影響,時常出現斷電、供電量不足等問題,同時,節(jié)約電能、提高路燈控制器的使用率,已經是城市路燈照明系統(tǒng)急需解決的問題。目前各大城市的路燈能源利用率普遍不高,路燈電費高昂,增加了管理和使用單位的經濟負擔,而傳統(tǒng)路燈控制器存在著智能化程度低、通訊穩(wěn)定程度差、管理控制不方便、路面照度分布不均等問題。 本課題設計的無線智能路燈系統(tǒng),采用ZigBee無線自組織網絡技術,可以實現路燈節(jié)能控制系統(tǒng)的智能化、信息化,而且具有可靠性高、成本低的優(yōu)勢。本系統(tǒng)由三部分組成:上位機系統(tǒng)管理軟件、無線路燈網關和無線路燈控制器。無線路燈網關作為ZigBee網絡協(xié)調器,可安置在監(jiān)控機房,一方面負責ZigBee網絡的建立和配置,另一方面通過以太網與上位機連接,實時反饋網絡狀態(tài)和接收上位機控制指令。無線路燈控制器作為ZigBee網絡路由器,安置在燈桿內部,可對照明電路電壓、電流、功率等參數進行監(jiān)測,并控制路燈的智能開啟和關閉。在ZigBee網絡中,它的功能是允許其他設備加入網絡和多跳路由維護。 論文首先介紹了課題研究背景、研究狀況以及目的和意義;其次分析了ZigBee技術標準,ZigBee網絡的設備類型,詳細介紹了ZigBee協(xié)議層組成,包括物理層、介質訪問控制層、網絡層和應用層;接著進行無線路燈智能系統(tǒng)總體設計,研究了系統(tǒng)網絡拓撲、路由協(xié)議等,本系統(tǒng)采用網狀網,Cluser-Tree算法和AODVjr算法相結合的路由協(xié)議,并在NS2平臺上進行了仿真分析,結果表明,重新設計的智能路燈路由協(xié)議性能優(yōu)于前兩者;隨后設計了基于CC2530的ZigBee射頻模塊,給出了原理圖和PCB設計中的注意事項;接著,進行ZigBee協(xié)議棧的軟件開發(fā),重點研究了Z-Stack協(xié)議棧的各個模塊和運行機制,設計了ZigBee模塊的啟動流程,并且實現了API接口的功能開發(fā);最后在陜西渭南進行系統(tǒng)安裝和測試,共安裝控制器93個,其中1個無線路燈網關,92個無線路燈控制器,實際運行結果表明系統(tǒng)運行良好,具有很高的推廣價值。
[Abstract]:With the development of urbanization in our country, the streetlight lighting system in cities is expanding. However, due to the bad weather conditions, there are problems such as power outage, insufficient power supply and so on. At the same time, electricity is saved. Increasing the utilization rate of streetlight controllers is an urgent problem for the urban streetlight lighting system. At present, the energy efficiency of street lamps in major cities is generally low, and the electricity consumption of street lamps is high, which increases the economic burden of the management and use units. The traditional street lamp controller has the problems of low intelligence, poor communication stability, inconvenient management and control, uneven distribution of road illumination. The wireless intelligent street lamp system designed in this paper adopts ZigBee wireless ad hoc network technology, which can realize the intelligent, information and high reliability of the street lamp energy saving control system. The system consists of three parts: upper computer system management software, wireless street lamp gateway and wireless street lamp controller. As ZigBee network coordinator, wireless street lamp gateway can be placed in the monitor room. On the one hand, it is responsible for the establishment and configuration of the ZigBee network, on the other hand, it connects with the host computer through Ethernet, feedback the network status and receives the control instructions of the host computer in real time. As the ZigBee network router, the wireless street lamp controller is placed inside the lamp pole. It can monitor the voltage, current, power and other parameters of the lighting circuit, and control the intelligent turn on and off of the street lamp. In ZigBee network, its function is to allow other devices to join the network and multi-hop route maintenance. Firstly, this paper introduces the research background, research status, purpose and significance, then analyzes the device types of ZigBee technical standard ZigBee network, and introduces the composition of ZigBee protocol layer in detail, including physical layer, medium access control layer. Network layer and application layer, then the overall design of wireless streetlight intelligent system is carried out, and the network topology, routing protocol and so on are studied. The system adopts the routing protocol which combines Cluser-Tree algorithm and AODVjr algorithm. The simulation analysis on NS2 platform shows that the redesigned intelligent street lamp routing protocol outperforms the former two. Then, the ZigBee RF module based on CC2530 is designed, and the schematic diagram and the matters needing attention in the PCB design are given. The software development of ZigBee protocol stack is carried out, and the various modules and operation mechanism of Z-Stack protocol stack are studied, the startup flow of ZigBee module is designed, and the function development of API interface is realized. Finally, the system installation and test are carried out in Weinan, Shaanxi Province. A total of 93 controllers are installed, including 1 wireless street lamp gateway and 92 wireless street lamp controllers. The actual operation results show that the system is running well and has high popularization value.
