该文采用两台PC工业控制计算机分别为现场上位机和远程监控机,以多个PLC可编程控制器和多个单片机系统作为下位机,构成计算机集散监控系统。对养殖水体的多环境因子进行自动监测和控制。特别是当鱼类出现不适或死亡时,鱼体会侧翻,腹部白色的区域会暴露,根据其特点,利用数字图像处理技术可以实现对养殖现场中鱼类的健康状况进行实时监视和预报。首先将摄像头拍摄的现场图像灰度化,然后去除各种噪声干扰,得到质量较好的图像,最后对该图像进行数据统计和识别。对如何实现这种图像处理进行了具体描述,结果表明该系统具有良好的实用效果。
This article uses two PC industrial control computer respectively on-site host computer and remote monitoring machine, with a number of PLC programmable logic controller and a number of single-chip microcomputer system as the next crew, constitute a computer monitoring system. Multi-environmental factors on aquaculture water for automatic monitoring and control. In particular, when fish become ill or die, the fish will roll over and the white areas of the abdomen will be exposed. According to its characteristics, the digital image processing technology can be used to monitor and forecast the health of the fish in the breeding field in real time. Firstly, the scene image taken by the camera is grayscale, and then various noise interferences are removed to obtain a better quality image. Finally, the data is statistically counted and identified. How to realize this kind of image processing has carried on the concrete description, the result indicated that this system has the good practical effect.
