摘 要
随着国家教育信息系统的逐渐完善和发展，教育的地位更加突出，这亦使得校园安全问题变得越来越重要。校园安全问题的困扰，促使相关人员建立更加完善的系统。安全信息系统的建立，以其获取信息速度快、交流方便、解决速度快为各大高校广泛研究应用。这一系统的建立，大大的完善了校园安全问题的历史遗留问题，促进了校园和谐文明健康的发展。
校园安全系统的应用，具体体现在对学校安全的监控能力。网络信息化时代的到来，网络的全方位覆盖，信息检测技术的不断成熟运用，增强了校园综合安防能力。在校园内覆盖摄像头，利用先进的监控技术，有效的实时保护学校人员的安全情况。全方位覆盖，可达到全方位监测，在发生安全事故第一时间做出反应，以及迅速的应急处理能力。对于违反校园安全的人员，监控技术的应用留下了铁证如山的录像证据，促进了校园安防的建设。
本文首先介绍了国内外校园安防体系建设的现状以及无线传感等技术的改革和发展趋势，对课题所涉及的物联网技术和Zigbee技术的应用进行介绍，并结合桂林电子科技大学的安保实际需求，从视频监控系统、门禁系统、红外线报警系统等多个方面对校园综合安防系统的建设进行研究，系统的各方面性能基本满足了预期目标。
多年来，在桂林电子科技大学保卫处的一线岗位上累积了丰富的工作经验，能够将日常工作中涉及到的治安、消防、交通、综合治理等方面的工作经验应用到研究中去，同时结合我校校区分布广、师生人数多、周边环境复杂及“校中村”带来的治安压力等现实问题，对校园的校园综合安防管理系统进行研究，并把当前的技术应用到现实工作中去，也体现了当前大学培养实用型、技能型人才的办学理念。

Abstract
With the gradual improvement and development of the national education information system, the status of education is becoming more and more prominent, which makes the problem of campus security become more and more important. Campus security issues, to promote relevant personnel to establish a more perfect system. The establishment of a security information system, with its access to information speed, easy to exchange, speed up for the major colleges and universities widely studied and applied. The establishment of this system, greatly improving the history of the problem of campus security issues, and promote the healthy development of a harmonious campus civilization.
The application of campus security system, which is embodied in the ability to monitor the safety of the school. The arrival of the era of network information, the full coverage of the network, information detection technology continues to mature, to enhance the ability of campus integrated security. In the campus coverage of the camera, the use of advanced monitoring technology, effective real-time protection of the safety of the school staff. Full coverage, can achieve a full range of monitoring, the first time in the event of a security response, as well as the rapid emergency response capacity. For violation of campus security personnel, application of monitoring technology of video evidence left hard to promote the construction of campus security.
This paper first introduces the trend of reform and development at home and abroad present situation of the construction of campus security system and wireless sensor technology, which involves the application of networking technology and Zigbee technology are introduced, and combining with the actual needs of the security of Guilin University of Electronic Technology, from the aspects of the video monitoring system, access control system, infrared alarm system etc. study on the construction of the integrated security system of campus, the performance of the system basically meets the expected goal.
Over the years, in the Security Department of Guilin University of Electronic Technology first post has accumulated rich experience, will be able to fire, security, transportation, and other aspects of comprehensive management work experience in daily work involved in the research, combining with our school campus wide distribution, the number of teachers and students, and the school in the complex surrounding environment the village brought police pressure and other practical problems, on the campus security management system on campus, and the current technique application to practical work, but also reflects the current universities to cultivate talents with practical skills of educational philosophy.
