【摘要】：人防工程是国家战时防御能力的重要组成部分,关系到面对危急情况和自然灾害的快速应急反应能力,按照规范对防护设备进行经常性的维护是防护工程危急时刻正常运行的重要保证。本课题研究在信息化的背景下,利用无线网络、检测技术、软件技术对人工维护情况进行监控、检测防护设备的状态并自动记录监视情况。本文分别对防护设备检测与无线通信问题提出新的方法,系统地设计了基于无线通信的人防工程支持维护检测系统,主要工作和创新性成果包括:1.针对防护门变形检测只能靠人工方式、且偏移精度低、成本高、实时性差的问题,创造性地通过一定的机械设计将触摸屏与变阻器应用于防护门扇在水平、垂直偏移距离的检测,并通过无线数字网络传送至数据服务器,从而可通过互联网对防护门偏移量信息进行查询。2.为简化机械结构设计,将三维电子罗盘应用于防护门的偏移检测,利用三维电子罗盘检测门扇的俯仰角、偏航角和横滚角,通过所提出的坐标变换算法,获得防护门状态信息,测试表明本文的设计方法能够快速精确地监视防护门的开度状态与记录防护设备维护动作。3.针对地下环境有线数据传输的局限性问题,设计了一种基于无线通信网络的传输方法。此无线传输方法依据地下空间特点系统规划传输网络,组网最多可跳传5级地址,并采用低频无线数据传输系统,提高数据传输距离与穿墙能力,解决地下空间无线数据传输问题,测试表明本文的设计方法能够在地下环境进行稳定的远距离数据传输。4.构建了人防工程监控系统,包括工程分类、多级传输地址的规划以及数据采集,通过轮询方式对检测系统进行访问,实现了对大量人防工程的维护自动监控及相关数据服务功能,以通过实际人防工程的试验。
[Abstract]:Civil air defense engineering is an important part of the national wartime defense capability, which is related to the rapid emergency response capability in the face of critical situations and natural disasters. Regular maintenance of protective equipment according to the specifications is an important guarantee for the normal operation of protective engineering at critical time. Under the background of information technology, this paper uses wireless network, detection technology and software technology to monitor the condition of manual maintenance, detect the status of protective equipment and record the monitoring situation automatically. In this paper, a new method for the detection of protective equipment and wireless communication is proposed, and the civil air defense engineering support maintenance and detection system based on wireless communication is designed systematically. The main work and innovative results include: 1. In view of the problem that the deformation detection of protective door can only rely on manual method, and the deviation accuracy is low, the cost is high and the real time is poor, the touch screen and rheostat are creatively applied to the protection door fan at the level through certain mechanical design. The vertical offset is detected and transmitted to the data server via the wireless digital network, so that the information about the offset of the guard door can be queried over the Internet. In order to simplify the mechanical structure design, the 3D electronic compass is applied to detect the migration of the guard door. The pitch angle, yaw angle and roll angle of the door fan are detected by the three-dimensional electronic compass. The state information of the protective door is obtained by the proposed coordinate transformation algorithm. The test shows that the design method of this paper can monitor the opening state of the protective door quickly and accurately and record the maintenance action of the protective equipment. 3. Aiming at the limitation of wired data transmission in underground environment, a transmission method based on wireless communication network is designed. According to the characteristics of underground space, the wireless transmission method can plan the transmission network systematically. The network can hop to 5 levels of address at most, and adopt the low frequency wireless data transmission system to improve the distance of data transmission and the ability of passing through the wall. To solve the problem of wireless data transmission in underground space, the test results show that the design method of this paper can carry on stable long-distance data transmission in underground environment. The monitoring system of civil air defense project is constructed, including project classification, multilevel transmission address planning and data acquisition, and the inspection system is accessed by means of polling. The functions of automatic maintenance monitoring and data service for a large number of civil air defense projects are realized in order to pass the test of actual civil air defense projects.
