Design and Implementation of Aquaculture Water Quality On-line Monitor System [PDF]
, 2016 海洋水产养殖一直是我国福建沿海主要经济产业之一，而花蛤又是主要海产经济贝类之一，特别在福建等地沿海产量较多。其中花蛤苗的主要产量来自于土池培育。该培育方法是利用天然近海滩涂及大水面进行露天养殖，相对于北方的室内工厂化育苗具有成本低、产量高、投资小、回收期短等特点，但具有严重依赖近海水文水质及气候等自然因素的特点，基于该特点，经考察发现，福建省内绝大部分天然渔场缺少对水质水文数据有效监测的手段，缺乏相应设备及信息监测系统，无法及时根据数据调整养殖策略，导致产量无法有效提高。 本文基于以上内容 ...

Research of Total Alkalinity Online Monitoring and Control System [PDF]
, 2016 总碱度是锅炉水处理过程中的一项重要指标，为保证锅炉的安全运行，需要对锅炉水总碱度进行精确测量并随时了解锅炉水中碱度的情况。目前，锅炉水总碱度的监测一般采用传统滴定的方法，即人工移取水样后再进行滴定的方式，但该方法不仅劳动强度大，还具有错误率较高、效率低下、管理混乱等问题，对安全生产也会产生一定的影响。针对以上问题，本文研究了一种对锅炉水总碱度进行自动测算、数据传输以及监控的总碱度在线监测和控制系统。 为了满足锅炉水总碱度自动测算和远程监测的需求，本文建立了锅炉水总碱度在线监测和控制系统 ...

Design and Implementation of Online Environmental Monitoring System Based on B/S [PDF]
, 2015 随着社会经济的快速发展和人类生活水平的逐步改善，人类在创造所需物质文明的同时，环境污染和生态破坏也在日益加重。传统的环境监测系统缺乏长时间的、具有代表性的监测数据，无法适应长期有效管理机制的需求，所以需要一种远程的在线环境监测系统。随着计算机网络技术的快速发展，建立一套自动化的环境在线自动监测系统，是环境监测发展的一个必然趋势。它能及时反映环境质量，实时跟踪污染源的变化，能准确预测各种突发环境事件。 针对传统监测方法的缺陷，本文基于B/S架构进行在线环境监测，利用GIS、ArcGISServer ...
