【摘要】：在一些城市地下,密布着各式各样的油气输送管道。这些地下危险气体输送管道的安全与广大人民群众的生命财产息息相关,尤其在人口密集居住区域更为突出。近年来,关于城市危险气体输送管道爆炸的公共安全事件也时有发生,因此加强对城市危险气体检测管理具有重要的社会意义。常规的危险气体输送管道检测系统采用定点监测方式,具有改造成本高、执行效率低等缺点。针对上述问题,本文设计了一款城市危险气体移动检测系统。该系统可以实现危险气体移动检测、危险地点定位(经纬度逆地址解析)、危险状态信息远程查询、中文报警短信发送、现场图像信息查看等功能。该系统由移动检测终端和嵌入式服务器端两部分组成。本文采用模块化的方法搭建硬件平台,对各个功能模块进行系统集成。移动终端软件设计包括开发环境搭建、Linux系统移植、驱动程序开发和应用程序开发等部分。移动终端负责把危险气体数据、GPS经纬度数据和现场图像数据,通过GPRS方式远程发送至嵌入式服务器端。嵌入式服务器端是该系统的核心部分,负责所有数据的接收和处理,实现了客户端远程访问服务器端信息的功能。本文着重讨论了嵌入式服务器端软件部分的设计与实现。此软件部分采用轻量级的设计理念,基于Linux系统和BOA服务器,通过Web开发技术、CGI接口技术和SQLite数据库技术,实现了一种B/S架构的远程监测系统。本文详细解释了嵌入式服务器端经纬度逆地址解析的过程,实现了GPS经纬度信息向地理地址信息的转换。最后对整个系统进行了联合调试,模拟实验表明所设计的系统能够有效地呈现危险气体状态和地理地址等信息,达到了预期的效果。该系统执行效率高、资源消耗少、小巧轻便,在城市危险气体检测系统设计中具有推广价值。
[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.
