【摘要】：在一些城市地下,密布著各式各樣的油氣輸送管道。這些地下危險(xiǎn)氣體輸送管道的安全與廣大人民群眾的生命財(cái)產(chǎn)息息相關(guān),尤其在人口密集居住區(qū)域更為突出。近年來(lái),關(guān)于城市危險(xiǎn)氣體輸送管道爆炸的公共安全事件也時(shí)有發(fā)生,因此加強(qiáng)對(duì)城市危險(xiǎn)氣體檢測(cè)管理具有重要的社會(huì)意義。常規(guī)的危險(xiǎn)氣體輸送管道檢測(cè)系統(tǒng)采用定點(diǎn)監(jiān)測(cè)方式,具有改造成本高、執(zhí)行效率低等缺點(diǎn)。針對(duì)上述問(wèn)題,本文設(shè)計(jì)了一款城市危險(xiǎn)氣體移動(dòng)檢測(cè)系統(tǒng)。該系統(tǒng)可以實(shí)現(xiàn)危險(xiǎn)氣體移動(dòng)檢測(cè)、危險(xiǎn)地點(diǎn)定位(經(jīng)緯度逆地址解析)、危險(xiǎn)狀態(tài)信息遠(yuǎn)程查詢、中文報(bào)警短信發(fā)送、現(xiàn)場(chǎng)圖像信息查看等功能。該系統(tǒng)由移動(dòng)檢測(cè)終端和嵌入式服務(wù)器端兩部分組成。本文采用模塊化的方法搭建硬件平臺(tái),對(duì)各個(gè)功能模塊進(jìn)行系統(tǒng)集成。移動(dòng)終端軟件設(shè)計(jì)包括開發(fā)環(huán)境搭建、Linux系統(tǒng)移植、驅(qū)動(dòng)程序開發(fā)和應(yīng)用程序開發(fā)等部分。移動(dòng)終端負(fù)責(zé)把危險(xiǎn)氣體數(shù)據(jù)、GPS經(jīng)緯度數(shù)據(jù)和現(xiàn)場(chǎng)圖像數(shù)據(jù),通過(guò)GPRS方式遠(yuǎn)程發(fā)送至嵌入式服務(wù)器端。嵌入式服務(wù)器端是該系統(tǒng)的核心部分,負(fù)責(zé)所有數(shù)據(jù)的接收和處理,實(shí)現(xiàn)了客戶端遠(yuǎn)程訪問(wèn)服務(wù)器端信息的功能。本文著重討論了嵌入式服務(wù)器端軟件部分的設(shè)計(jì)與實(shí)現(xiàn)。此軟件部分采用輕量級(jí)的設(shè)計(jì)理念,基于Linux系統(tǒng)和BOA服務(wù)器,通過(guò)Web開發(fā)技術(shù)、CGI接口技術(shù)和SQLite數(shù)據(jù)庫(kù)技術(shù),實(shí)現(xiàn)了一種B/S架構(gòu)的遠(yuǎn)程監(jiān)測(cè)系統(tǒng)。本文詳細(xì)解釋了嵌入式服務(wù)器端經(jīng)緯度逆地址解析的過(guò)程,實(shí)現(xiàn)了GPS經(jīng)緯度信息向地理地址信息的轉(zhuǎn)換。最后對(duì)整個(gè)系統(tǒng)進(jìn)行了聯(lián)合調(diào)試,模擬實(shí)驗(yàn)表明所設(shè)計(jì)的系統(tǒng)能夠有效地呈現(xiàn)危險(xiǎn)氣體狀態(tài)和地理地址等信息,達(dá)到了預(yù)期的效果。該系統(tǒng)執(zhí)行效率高、資源消耗少、小巧輕便,在城市危險(xiǎn)氣體檢測(cè)系統(tǒng)設(shè)計(jì)中具有推廣價(jià)值。
[Abstract]:Underground in some cities, there are a variety of oil and gas pipelines. The safety of these underground dangerous gas pipelines is closely related to the lives and properties of the people, especially in densely populated areas. In recent years, public safety incidents of urban hazardous gas pipeline explosion also occur from time to time, so it is of great social significance to strengthen the detection and management of urban dangerous gas. The conventional inspection system of dangerous gas pipeline adopts fixed-point monitoring, which has the disadvantages of high cost and low efficiency. In view of the above problems, this paper designs a mobile detection system for urban hazardous gas. The system can realize the functions of dangerous gas movement detection, dangerous location (longitude and latitude inverse address analysis), remote inquiry of dangerous state information, Chinese alarm short message sending, scene image information checking and so on. The system consists of mobile detection terminal and embedded server. In this paper, the modular method is used to build the hardware platform, and the system integration of each functional module is carried out. The design of mobile terminal software includes development environment, Linux system porting, driver development and application program development. The mobile terminal is responsible for sending the dangerous gas data, GPS longitude and latitude data and field image data to the embedded server through GPRS. The embedded server is the core part of the system, which is responsible for receiving and processing all the data, and realizes the function of remote accessing the information of the server. This paper focuses on the design and implementation of embedded server-side software. Based on Linux system and BOA server, a remote monitoring system based on B / S architecture is realized by using Web development technology, CGI interface technology and SQLite database technology. In this paper, the process of inverse address resolution of latitude and longitude on the embedded server is explained in detail, and the transformation of GPS latitude and longitude information to geographic address information is realized. Finally, the system is debugged jointly, and the simulation results show that the system can effectively present the information of dangerous gas state and geographical address, and achieve the desired results. The system is of high efficiency, low resource consumption, small and light, and is worth popularizing in the design of urban dangerous gas detection system.
