摘　　要：随着移动互联网技术的发展,传统的数据采集系统框架设计面临高耦合、移植性差和维护成本高等难题,制约了数据采集系统的移动化发展。为了提高渔业资源调查数据采集系统模块的内聚性和易维护性,提出一种以移动应用层、Web服务层、业务服务层的三层系统框架设计,采用Nginx构建Web服务器实现反向代理作为路由控制核心,通过以NodeJS为核心的Koa2框架搭建业务服务层提供Restful风格的接口服务,实现前后端分离设计的渔业资源调查数据采集系统。结果显示,该框架重构后系统运行稳定可靠,扩展性高,可为构建高效的数据采集系统提供参考。With the development of mobile Internet technology,the framework design of traditional data acquisition system is facing with the problems of high coupling,poor portability and high maintenance cost,which have restricted the mobile development of data acquisition system.In order to improve the cohesion and maintainability of the modules of fishery resource survey data acquisition system,this paper proposes a three-layer(mobile application layer,Web service layer and business service layer)system framework design,uses Nginx to build Web server to realize reverse proxy as the core of routing control,provides Restful style interface services by building the business service layer based on the Koa2 framework that takes NodeJS as the core,and finally implements a fishery resource survey data acquisition system with the front-end and back-end separation design.The results show that the system runs stably and reliably with high expansibility after the reconstruction of the framework,which provides references for constructing an efficient data acquisition system.
