【摘要】：傳統(tǒng)的有線消防報警系統(tǒng)存在著安裝復(fù)雜，成本較高等問題，整個網(wǎng)絡(luò)只能依賴有線電纜進行數(shù)據(jù)傳輸，，所以當(dāng)火災(zāi)發(fā)生或節(jié)點發(fā)生故障時，整個監(jiān)測網(wǎng)絡(luò)極易陷入癱瘓狀態(tài)。這種方式已經(jīng)不能勝任現(xiàn)代社會對于消防工作的需求。隨著無線通信技術(shù)、嵌入式技術(shù)、傳感器技術(shù)的快速發(fā)展，消防報警系統(tǒng)在功能結(jié)構(gòu)上都有了很大的變化，出現(xiàn)了無線消防遠程監(jiān)控系統(tǒng)。而消防監(jiān)控網(wǎng)關(guān)作為無線消防遠程監(jiān)控系統(tǒng)的重要一環(huán)，是連接感知網(wǎng)絡(luò)與傳統(tǒng)通信網(wǎng)絡(luò)的橋梁，是整個系統(tǒng)實時性、可靠性的重要保障。本文針對現(xiàn)有消防系統(tǒng)存在的問題及需求，設(shè)計開發(fā)了一種面向消防遠程監(jiān)控的無線傳感器網(wǎng)絡(luò)網(wǎng)關(guān)。論文的主要工作如下： 1）基于CC2530芯片對消防監(jiān)控網(wǎng)關(guān)上的Zigbee協(xié)調(diào)器節(jié)點進行了軟硬件的設(shè)計。在硬件上設(shè)計了兩種不同通信接口的協(xié)調(diào)器，串口通信與USB通信兩種方式。在軟件上對協(xié)調(diào)器的組網(wǎng)流程以及數(shù)據(jù)通信流程進行了設(shè)計。 2）通過三種方式實現(xiàn)了Android平臺與Zigbee協(xié)調(diào)器之間的通信。第一種為串口通信，利用了NDK本地開發(fā)工具及JNI技術(shù)實現(xiàn)了串口操作動態(tài)鏈接庫，Android通過調(diào)用這個庫可實現(xiàn)對串口的操作。第二種為USB HOST通信方式，通過利用USB相關(guān)類在Android應(yīng)用層實現(xiàn)了PL2303HX芯片的驅(qū)動，從而獲取USB設(shè)備的輸入輸出流實現(xiàn)通信。第三種則是通過利用Arduino平臺作為中繼，從而實現(xiàn)數(shù)據(jù)透傳的功能。 3）對消防監(jiān)控網(wǎng)關(guān)系統(tǒng)的功能進行了設(shè)計。實現(xiàn)了本地數(shù)據(jù)存儲、報警數(shù)據(jù)上傳、穿透NAT的遠程控制、基于achartengine的數(shù)據(jù)可視化等功能，滿足了無線消防遠程監(jiān)控系統(tǒng)的需要。 該網(wǎng)關(guān)系統(tǒng)已經(jīng)在某文物保護單位應(yīng)用，通過對環(huán)境信息的實時監(jiān)測以及感知數(shù)據(jù)、報警信息的可靠傳輸，能夠及時準(zhǔn)確的發(fā)現(xiàn)異常情況并迅速報警。
[Abstract]:The traditional wired fire alarm system has some problems such as complicated installation and high cost. The whole network can only rely on cable for data transmission. Therefore, when the fire occurs or the node fails, the whole monitoring network is prone to be paralyzed. This way has not been able to meet the needs of modern society for fire work. With the rapid development of wireless communication technology, embedded technology and sensor technology, the function structure of fire alarm system has changed greatly. As an important link of wireless remote fire control system, fire monitoring gateway is a bridge between perceptual network and traditional communication network. It is an important guarantee for the real-time and reliability of the whole system. In this paper, a wireless sensor network gateway for remote monitoring and control of fire protection is designed and developed according to the existing problems and requirements of the fire fighting system. The main work of this paper is as follows: 1) the software and hardware of the Zigbee coordinator node closed by the fire control network are designed based on CC2530 chip. In hardware, two kinds of communication interface coordinator, serial communication and USB communication are designed. In the software, the network flow and data communication flow of the coordinator are designed. 2) the communication between Android platform and Zigbee coordinator is realized in three ways. The first is serial port communication. The serial port operation dynamic link library is realized by using NDK local development tool and JNI technology. Android can realize the operation of serial port by calling this library. The second is the USB HOST communication mode. The driver of the PL2303HX chip is realized by using the USB correlation class in the Android application layer, so as to obtain the input and output stream of the USB device to realize the communication. The third is to realize the function of data transmission by using Arduino platform as relay. 3) the function of fire control gateway system is designed. The functions of local data storage, alarm data upload, remote control of penetrating NAT and data visualization based on achartengine are realized. The gateway system has been used in a cultural relic protection unit. Through the real-time monitoring of environmental information and the reliable transmission of alarm information and perceptual data, the gateway system can timely and accurately detect the abnormal situation and alarm quickly.
