摘要由于目前的安保需要，很多场所禁止闲杂人员闯入，防止非法入侵。为了避 免造成对这些场所造成的损失等。近年来，一些对安保要求较高的场所，如：公 安、银行特别是军事设施对可以进行现场记录的报警系统的需求与日俱增。 81359

目前针对于入侵报警系统，大多数场所选择视频监控来进行现场的记录。随 着视频识别技术的发展，视频监控也可以做到当有非法入侵的时候来提醒发出警 报。但是视频识别的入侵警报受到环境的影响比较大，且算法较复杂报警不是非 常的及时。大多数还只是用来记录入侵场景。因此对于值班人员的工作没带来过 多的减轻，值班人员仍需进行巡逻等传统方式来保障安全性。 

为了克服视频监控的缺点。我们设计了基于对射型光电传感器的入侵报警系 统，本系统采用对射型光电传感器来采集入侵的信号，利用单片机的信号转换技 术来将传感器识别到的电压信号转化为计算机能够识别的数字信‘0’‘1’，在 得到两个不同的信号之后采用 Socket 通信技术将信号传输给计算机系统。收到 入侵信号，调用 JMF 框架打开摄像头采集入侵的场景传输给服务端方便后期的调 用。 

本系统使用对射型光电传感器获得的信号有很高的可靠性，同时采用摄像头 拍摄当时的场景并且可以及时的在移动设备上查看更加的及时。克服了视频监控 准确率低的缺点，及时通知安保人员，大大减轻了安保人员的工作压力。

Abstract Due to the current security requirements, many places prohibited without fixed duties into, to prevent the illegal invasion。 In order to avoid losses caused by these places and so on。 In recent years, some of the security requirements of the higher places, such as: the needs of public security, banking in particular military facilities on site can be recorded alarm system growing。

Currently in intrusion alarm systems for the majority of site selection for live video surveillance recording。 With the development of video recognition technology, video surveillance can also be done when there is time to remind the illegal invasion of alert。 But the intrusion alarm video identified by the environmental impact of larger, more complex algorithms and alarm is not very timely。 Most just used to  record  the intrusion scenario。 So for the work of staff on duty did not bring much relief, still on duty patrolling the traditional way to guarantee security。

In order to overcome the shortcomings of video surveillance。 We  designed based-beam photoelectric sensor intrusion alarm system, the system uses beam photoelectric sensor to capture the invasion signal, using SCM signal conversion techniques to sensor detects the voltage signal into a computer can recognize the digital signal '0''1', after getting two different signals using Socket communication technology sends the signal to the computer system。 Intrusion signal received calls JMF open the camera frame capture invasion scene transmitted to the server to facilitate the call later。

The system uses radio signals obtained by photoelectric sensor has a high reliability, while using the camera to shoot at the scene and can be timely viewed on mobile devices more timely。 To overcome the disadvantages of low accuracy rate video surveillance, inform security personnel, security personnel greatly reducing the work pressure。
