The demands of post analysis and processing software for data acquisition system are analyzed, the o-verall structure of this software is designed and the module components of this software are determined. In order to reduce the repeated development, a data storage solution is designed. In that way, any acquisition system being developed in the future could achieve the performance of data post analysis and processing with the post a-nalysis and processing software as long as it runs in the same storage solution. A secondary development is not needed. The modules which constitute the post analysis and processing software and the implementation methods of the modules are described. The software uses the MFC to implement, and uses the TeeChart control. The post analysis and processing software is designed and implemented, which has the advantages of strong versatility, simple operation and good effect.%分析了总线数据采集系统事后分析处理软件的需求,设计了软件的总体结构,确定了软件的模块组成.为减少重复开发,设计了采集系统的数据存储方案,使将来开发研制的采集系统,只要按照该存储方案存储数据,便可以利用该事后分析处理软件实现其采集数据的事后分析处理功能,无需二次开发.描述了事后分析处理软件各模块的功能和实现方法；采用MFC实现,利用了TeeChart控件.设计实现的数据采集系统事后分析处理软件通用性强、操作简单,效果良好.
