【摘要】："十一五"以来,在党中央、国务院和地方各级党委、政府领导下,各地、各有关部门认真贯彻落实国务院《关于进一步加强消防工作的意见》,我国消防工作取得了明显进步。但是,随着我国经济社会快速发展,公众消防安全意识与现代社会管理要求不相适应的问题还比较突出,消防安全形势依然严峻。为提高消防安全质量,降低消防安全隐患,消防部门需要组织执行消防巡检工作,但现如今的消防巡检工作主要存在以下问题:一是即时讯息传递受阻,消防部门主要负责人无法监督消防巡检人员的真实工作情况;二是巡检资料收集整理困难,巡检工作记录多数采用纸质保留,无法及时进行巡检结果的分析与统计;三是巡检计划管理不当,无法形成流程化管理机制。为更好的服务消防管理系统,进一步巩固消防工作的基础,本文从消防巡检工作入手,设计了结合QR码水印的消防巡检系统。QR码具有纠错能力强、容量大、易于识别等优点,巡检系统中通过移动终端扫描QR码开展巡检工作,既实现了巡检工作的无纸化,又保证了巡检人员的真实到位率。但是由于QR码采用公开的编码模式,缺少严格意义上的防伪方法,使它应用于消防巡检系统中时保密性略显不足。而数字水印技术利用图像信息中存在数据冗余的特性,将消防巡检过程中的消防设施的基本信息隐藏在QR码中,以达到信息隐藏、增强巡检安全等作用。因此,结合数字水印技术和QR码技术,能够在很大程度上的提高QR码和消防巡检系统的安全性。本文的主要工作如下:研究基于QR码的大容量数字水印算法。在分析QR码的编码解码原理后,根据QR码的纠错编码特性,通过密钥控制水印信息嵌入位置,调整QR码模块边界的方法将水印信息嵌入在模块交界处。实验表明,该算法在可嵌入容量、抗缩放攻击方面的性能都优于现有算法。设计开发结合QR码水印的消防巡检系统。该系统分为两个子系统,一是web端的消防巡检管理系统,它是基于Jeesite框架进行开发的web项目,实现了流程化管理巡检计划、系统管理消防设施资源等功能,系统还利用了大容量QR码水印算法,将消防设施的基本信息嵌入到与每个消防设施相对应的QR码中。二是手机端的消防巡检移动终端,实现了查询巡检计划,利用从消防巡检管理系统中传输过来的QR码扫描巡检消防设施,上传巡检结果等功能。消防巡检系统的使用,提高了消防部门的信息化水平、消防巡检的工作效率,有效管理了消防设施的基本情况,保证了巡检人员的真实到位率,解决了巡检结果及时上传等问题。
[Abstract]:Since the 11th Five-Year Plan, under the leadership of the Party Central Committee, the State Council, and local party committees and governments at various levels, all localities and departments concerned have conscientiously implemented the State Council's opinions on further strengthening Fire Control work, and China's fire control work has made remarkable progress. However, with the rapid development of China's economy and society, the public's awareness of fire safety does not adapt to the requirements of modern social management, and the fire safety situation is still grim. In order to improve the quality of fire safety and reduce the hidden dangers of fire safety, the fire department needs to organize and carry out the fire protection inspection work. However, nowadays the fire protection inspection work mainly has the following problems: first, the instant message transmission is blocked, The main person in charge of the fire department can not supervise the real work situation of the fire patrol personnel; second, it is difficult to collect and organize the patrol inspection data, most of the inspection records are kept on paper, and the analysis and statistics of the inspection results can not be carried out in time; Third, the inspection plan is improperly managed, unable to form the flow management mechanism. In order to better serve the fire control management system and further consolidate the foundation of the fire fighting work, this paper designs the fire patrol inspection system. QR code combining with the QR code watermark has the advantages of strong error correction ability, large capacity, easy recognition and so on. In the system, the mobile terminal scanning QR code is used to carry out the inspection work, which not only realizes the paperless inspection work, but also ensures the real arrival rate of the patrol personnel. However, due to the open coding mode of QR code, the security of QR code used in fire patrol system is slightly insufficient due to the lack of anti-counterfeiting method in strict sense. Digital watermarking technology uses the feature of data redundancy in image information to hide the basic information of fire protection facilities in QR code in order to achieve information hiding and enhance the security of patrol inspection. Therefore, the combination of digital watermarking technology and QR code technology can greatly improve the security of QR code and fire patrol system. The main work of this paper is as follows: a mass digital watermarking algorithm based on QR code is studied. After analyzing the encoding and decoding principle of QR code, according to the error correcting coding characteristics of QR code, the embedding position of watermark information is controlled by key, and the watermark information is embedded at the interface of QR code module by adjusting the QR code module boundary. Experimental results show that the proposed algorithm is superior to the existing algorithms in terms of embeddable capacity and resistive scaling attack. Design and develop a fire protection inspection system based on QR code watermark. The system is divided into two subsystems. One is the fire patrol management system in the web terminal. It is a web project developed based on the framework of Jeesite. The system realizes the functions of managing the patrol plan and managing the fire protection facilities resources, etc. The system also makes use of the large capacity QR code watermarking algorithm to embed the basic information of the fire protection facility into the corresponding QR code of each fire protection facility. The second is the mobile terminal of the mobile phone, which realizes the query and inspection plan, uses the QR code transmitted from the fire patrol management system to scan the fire protection facilities, uploads the patrol results and so on. The use of the fire protection patrol system improves the level of information of the fire department, the efficiency of the fire protection inspection, the effective management of the basic situation of the fire protection facilities, and ensures the real arrival rate of the patrol personnel. Solve the problem of timely upload of inspection results.
