摘　　要：为了实现家庭安防系统中多摄像头的现场视频图像采集和实时远程视频报警功能,通过非探测器触发,由多个摄像头循环采集数据,根据While循环的计数端口变量和摄像头的数量确定具体算法,将其结果作为索引号调用对应的摄像头采集数据.运用了美国国家仪器公司的DataSocket技术进行现场数据的远程读取、保存等操作,并以彩信的形式将数据发往用户的手机.设计了USB接口检测程序,确定所插的每一个摄像头的序号.此外,利用沿检测概念,实现了用常闭探测器代替比其贵五六倍的常开探测器.系统测试结果表明,系统性能稳定,各个摄像头和模块之间的配合完全符合视频快速采集、传输、报警、记录的要求,并可将采集的信息以手机短信方式通知用户;没有发生误报和漏报情况,达到了预期的效果.The live video image acquisition of multi camera and real - time remote data transmission using LabWIEW 2010 platform were carried out in home safety alarm system. With alarm not excitated by detector, the data of multiple cameras were collected circularly and processed , which was determined by specific algorithm based on variable counting ports in while loop and the number of cameras. DataSocket technology of national instruments of America was used to read and storage remote data and send the data to the user＇ s mobile phone in the form of MMS. USB interface detection was programmed to keep camera - detector - channel of A/ D card matching. In addition, edge detection was employed in the program to use normal close detector instead of normal open one whose price was five or six times that of the former. Test results show that performance of the system is reliable, the system is able to collect multi - target video signals accurately, transmit video images and alarm to terminal unit by network combining with other sensors and program modules, and send SMS to user＇ s mobile without false positive and false negative alarm appeared in repeating tests, so it achieves expected goal.
