As the complexity and variety of the crime form in the new era,the traditional electronic data forensics has been dififcult to meet the demand of the judicial work. Combined with the actual needs in the police force, this paper proposes an electronic data cloud platform. It can support for data reuse, inter regional cooperation and networking,And it has made significant progress in the billion level data. In addition, depth mining platform,correlation analysis and other technology,has an important role in the fight against crime. This paper compared with the traditional pattern of evidence collection, and combined with the actual needs in the police force, expatiates the necessity of the construction of data clouds gathering platform.This paper also takes some discussion on the constructive problem related to data clouds gathering platform, then puts forward views that judicial organs should step up cooperation with relevant institutions.%新时代犯罪形态的复杂多样化，使得传统的电子数据取证已难以满足新时代司法工作的需求。结合实战部门的迫切需要，文章提出了一种电子数据云平台，该平台能够支持跨区域合作、联网工作，还在数亿级别的大数据运算方面取得了重大进展。此外，平台提供的深度挖掘、关联分析等技术，对深入打击犯罪团伙具有突破性的意义。文章对比传统取证模式，并结合实战部门的工作需求，对平台建设的相关性问题进行讨论，提出了司法机关应加大与相关机构合作的观点。
