区域恶臭在线监控平台设计与实现

为提高恶臭污染管理水平和恶臭事件应急处理能力，填补国内区域恶臭在线监控体系建设的空白，提出了区域恶臭在线监控平台的整体设计方案。依据网络负载均衡和按需动态扩展的思想设计恶臭实时监测和远程监控两项功能。远程监控采用远程桌面协议(RDP)技术，实现参数调整、超限报警、分级采样等功能，同时设计一种基于高级加密标准(AES)及MD5数字签名技术的混合算法以弥补RDP的安全缺陷。平台已在天津市滨海新区大港石化产业园上线试运行，初步实现各项设计功能，为后续恶臭扩散模型研究和恶臭污染防控积累数据和经验，并为恶臭在线监测系统最终融入我国环保物联网做技术准备。

Design and implementation of regional malodor on-line monitoring platform

To improve malodor management and emergency response ability, this paper proposed a regional malodor on-line monitoring platform solution. Referring to network-load equilibrium and dynamic extendibility, the platform implemented real-time monitoring and remote monitoring. The remote monitoring module corresponding to the Remote Desktop Protocol (RDP) could adjust a terminal's parameters, alarm beyond limit and sample at different grades. Based on Advanced Encryption Standard (AES) and MD5 digital-signature technology, a combined algorithm was designed to improve the safety of the RDP. The platform has been piloting in Dagang Petrochemical Industrial Park in Tianjin Binhai New Area，which could accumulate data and experience for the research of future malodor diffusion model as well as malodor pollution control, and make technical preparation for malodor on-line monitoring system to merge into the Internet of Things (IOT) for environmental protection.
