基于无线网络的实验室智能值守系统的设计

Design of Laboratory Intelligent Duty Watch System Based on Wireless Network

将智能监控引入实验室安保建设中,提出了基于无线网络的实验室智能值守系统的设计方案。该系统基于图像处理的相关理论,利用目标出现前后图像的灰度会产生较大变化的特点,用差分法将当前图像与多高斯法建立的背景模型进行差分运算,一旦结果超过阈值就可以确定目标进入。该系统由摄像头、OK6410嵌入式开发平台、无线网络和移动终端组成。OK6410对摄像头摄取的图像进行处理,如果发现目标进入,立刻声音报警并将现场图像通过无线网络传输到工作人员的移动终端上,实现了无人值守实验室监控的智能化和网络化。

Laboratory Intelligent Duty Watch System based on wireless network was put forward using intelligent monitor-ing idea in laboratory security construction. The difference of current image and the background model built by multipleGauss method was calculated because of great gray changes produced by target appearance. Target entry can be determined once the results exceed the threshold value. The system is composed of camera,OK6410 embedded development platform,wireless network and mobile terminals. An audio alarm was given and scene images were sent to mobile terminals of the staff through wireless network when target entried. Therefore,the intelligent and networked monitoring of unmanned laboratory was realized.
