摘　　要：通过分析传统污水处理监控系统的不足之处,参考HJ/T212-2005污染源在线自动监控(监测)系统数据传输标准,充分利用Google App Engine(GAE)平台的特点,了解Saa S系统服务的诸多关键技术,提出一种基于Saa S模式的污水处理监控系统。系统通过引入元数据机制驱动不同租户的个性化需求、命名空间机制保证数据操作安全、配置数据转换规则方式兼容各类数据采集设备,由OAuth认证机制验证第三方软件接入系统权限并利用GAE平台动态伸缩资源的特点增强负载能力,是一个可配置、可扩展的Saa S系统。详细阐述了该Saa S系统的组成和关键实现技术,并通过与传统污水处理系统对比验证了其优势。By analysing the. disadvantages of traditional sewage treatment monitoring system, referring the data transmission standard of online monitoring system of HJ/T212-2005 pollution sources, using the features of Google App Engine （GAE） platform, and comprehending key technologies of SaaS system, we propose an SaaS-based sewage treatment monitoring system. The system introduces metadata mechanism to drive the personalised demands of different tenants, uses namespace mechanism to ensure the safety of data operation, configurates data conversion rules to make various data collection devices be compatible with each other, uses OAuth authentication mechanism to validate the privilege of the third-part software accessing to system, and uses the feature of GAE platform in dynamic scaling the resources to enhance load capability. It is a eonfigurable and extensible SaaS platform. We give a detailed description on the constitution of the SaaS system and the key technologies of its implementation, and verify its advantages by comparing it with traditional sewage treatment system.
