This project includes three parts: the research of scene business characteristics, the application research of workflow technology and data quality management technology, and the development of data intelligent filling system. The project is based on the development of intelligent data filling system for typical application scenarios in the industry. Through the investigation of existing scenarios, a typical data filling scenario template that can be applied to actual business is formed to support fast and accurate data filling in field operation environment, and data intelligent verification is carried out on the data filling in real time. The data collection personnel can collect and report the task real-time data in time, quickly and accurately, and realize the convenience, standardization and intelligence of data filling.
