【摘要】：在一些城市地下,密布著各式各樣的油氣輸送管道。這些地下危險氣體輸送管道的安全與廣大人民群眾的生命財產(chǎn)息息相關,尤其在人口密集居住區(qū)域更為突出。近年來,關于城市危險氣體輸送管道爆炸的公共安全事件也時有發(fā)生,因此加強對城市危險氣體檢測管理具有重要的社會意義。常規(guī)的危險氣體輸送管道檢測系統(tǒng)采用定點監(jiān)測方式,具有改造成本高、執(zhí)行效率低等缺點。針對上述問題,本文設計了一款城市危險氣體移動檢測系統(tǒng)。該系統(tǒng)可以實現(xiàn)危險氣體移動檢測、危險地點定位(經(jīng)緯度逆地址解析)、危險狀態(tài)信息遠程查詢、中文報警短信發(fā)送、現(xiàn)場圖像信息查看等功能。該系統(tǒng)由移動檢測終端和嵌入式服務器端兩部分組成。本文采用模塊化的方法搭建硬件平臺,對各個功能模塊進行系統(tǒng)集成。移動終端軟件設計包括開發(fā)環(huán)境搭建、Linux系統(tǒng)移植、驅(qū)動程序開發(fā)和應用程序開發(fā)等部分。移動終端負責把危險氣體數(shù)據(jù)、GPS經(jīng)緯度數(shù)據(jù)和現(xiàn)場圖像數(shù)據(jù),通過GPRS方式遠程發(fā)送至嵌入式服務器端。嵌入式服務器端是該系統(tǒng)的核心部分,負責所有數(shù)據(jù)的接收和處理,實現(xiàn)了客戶端遠程訪問服務器端信息的功能。本文著重討論了嵌入式服務器端軟件部分的設計與實現(xiàn)。此軟件部分采用輕量級的設計理念,基于Linux系統(tǒng)和BOA服務器,通過Web開發(fā)技術、CGI接口技術和SQLite數(shù)據(jù)庫技術,實現(xiàn)了一種B/S架構的遠程監(jiān)測系統(tǒng)。本文詳細解釋了嵌入式服務器端經(jīng)緯度逆地址解析的過程,實現(xiàn)了GPS經(jīng)緯度信息向地理地址信息的轉(zhuǎn)換。最后對整個系統(tǒng)進行了聯(lián)合調(diào)試,模擬實驗表明所設計的系統(tǒng)能夠有效地呈現(xiàn)危險氣體狀態(tài)和地理地址等信息,達到了預期的效果。該系統(tǒng)執(zhí)行效率高、資源消耗少、小巧輕便,在城市危險氣體檢測系統(tǒng)設計中具有推廣價值。
[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.
