【摘要】：無線網(wǎng)絡(luò)技術(shù)因其靈活性、移動(dòng)性、便捷性在各個(gè)領(lǐng)域得到了廣泛應(yīng)用,并在某些特殊網(wǎng)絡(luò)應(yīng)用中充當(dāng)重要角色。燈光終端控制系統(tǒng)對(duì)無線網(wǎng)絡(luò)技術(shù)同樣存在應(yīng)用需求,此前的應(yīng)用停留在單體單個(gè)的路燈控制,對(duì)廣泛的舞臺(tái)燈光、景觀燈光的控制缺少應(yīng)用,因此設(shè)計(jì)一種高效、靈活的廣義無線燈光終端控制系統(tǒng)具有很高的應(yīng)用價(jià)值。在研究傳統(tǒng)燈控系統(tǒng)的不足之后,本文提出了一種基于無線網(wǎng)絡(luò)的燈光終端控制系統(tǒng),其以無線組網(wǎng)為核心并合理優(yōu)化了系統(tǒng)性能。本文根據(jù)燈光控制系統(tǒng)的需求和應(yīng)用場(chǎng)合特點(diǎn),選擇WiFi協(xié)議作為系統(tǒng)無線組網(wǎng)技術(shù);在應(yīng)用層選擇ACN協(xié)議以實(shí)現(xiàn)對(duì)燈光終端的控制;在網(wǎng)絡(luò)層通過無線AP構(gòu)建了Infra基礎(chǔ)結(jié)構(gòu)型網(wǎng)絡(luò),然后選擇了RIP路由協(xié)議來交換網(wǎng)絡(luò)IP數(shù)據(jù)包;在系統(tǒng)的安全性和可靠性方面,本文選用了WPA2加密算法以提高系統(tǒng)安全性,設(shè)計(jì)了故障處理模塊并選擇了相應(yīng)的備份機(jī)制以保障可靠性。在網(wǎng)絡(luò)系統(tǒng)同步方面,由于NTP協(xié)議在燈光控制系統(tǒng)的局限性,為了提高系統(tǒng)可靠性,本文在NTP協(xié)議的基礎(chǔ)上,提出了改進(jìn)的LNTP協(xié)議,通過對(duì)應(yīng)的系統(tǒng)流程和算法來保證系統(tǒng)的可靠同步;同時(shí)研究和分析了無線網(wǎng)絡(luò)的覆蓋范圍特性及干擾問題;通過分析信號(hào)傳播模型及頻道分配特性后提出了最優(yōu)頻段分配方法及抗干擾方式。最后本文驗(yàn)證了時(shí)鐘同步系統(tǒng)的有效性,并且具體設(shè)計(jì)了WiFi模塊的收/發(fā)流程。本文設(shè)計(jì)的基于無線網(wǎng)絡(luò)的燈光終端控制系統(tǒng)具有靈活度高、可拓展性高、易于部署等優(yōu)點(diǎn),可利用于體育場(chǎng)、演播廳、展館等領(lǐng)域還可用于老舊場(chǎng)館的燈光改造系統(tǒng)。
[Abstract]:Wireless network technology has been widely used in various fields because of its flexibility, mobility and convenience, and plays an important role in some special network applications. The lighting terminal control system also has the application demand to the wireless network technology, the previous application stays in the single individual street lamp control, to the widespread stage light, the landscape light control lacks the application, therefore designs a kind of high efficiency, The flexible generalized wireless lighting terminal control system has high application value. After studying the shortcomings of the traditional lamp control system, this paper proposes a kind of lighting terminal control system based on wireless network, which takes wireless networking as the core and optimizes the system performance. According to the demand of the lighting control system and the characteristics of the application situation, the WiFi protocol is chosen as the wireless networking technology of the system, and the ACN protocol is selected in the application layer to realize the control of the lighting terminal. In the network layer, Infra infrastructure network is constructed through wireless AP, then RIP routing protocol is chosen to exchange IP packets in the network layer, and WPA2 encryption algorithm is selected to improve the system security in terms of system security and reliability. The fault processing module is designed and the corresponding backup mechanism is selected to ensure the reliability. In the aspect of network system synchronization, because of the limitation of NTP protocol in lighting control system, in order to improve the reliability of the system, this paper proposes an improved LNTP protocol based on NTP protocol. Through the corresponding system flow and algorithm to ensure the reliable synchronization of the system, at the same time, the coverage characteristics and interference problems of wireless network are studied and analyzed. After analyzing the signal propagation model and channel allocation characteristics, the optimal frequency band allocation method and anti-jamming method are proposed. Finally, the validity of clock synchronization system is verified, and the receiving / sending flow of WiFi module is designed. The light terminal control system based on wireless network has the advantages of high flexibility, high expansibility and easy deployment. It can be used in the fields of stadium, studio, exhibition hall and so on.
