基于区块链的发电厂样品委托检测物流及信息管理系统研究

Research on Inspection Logistics and Information Management System for Power Plant Sample Commission Based on Blockchain

针对发电厂样品数量多、检测流程涉及地域范围广、时间跨度长、中间环节多等问题,设计一个基于区块链的发电厂样品物流及信息管理系统。介绍了基于二维码+动态码的样品标识技术,基于区块链和Python Django Web框架样品管理技术。设计了样品标识子系统、样品物流子系统和样品信息流子系统,最后通过使用Python机器语言中Django模块完成程序的架构部分,通过结合MySQL数据库,采用B/S(Browser/Server,浏览器/服务器)模式,以完成面向Web端的应用系统。该应用系统能对发电厂样品实现全过程闭环管理,实现了动态实时灵活的控制访问,提升了样品检测的可靠性、及时性和可溯源性。

Aiming at the problems of a large number of samples in the power plant,the inspection procedures involve a wide range of regions,the long time span,and the many intermediate links,an inspection logistics and information management system of power Plant Sample based on blockchain was designed.Introduced the sample identification technology based on QR code+dynamic code,and sample management technology based on blockchain and Python Django Web framework.Designed three subsystems including the sample identification system,the sample logistics system and the sample information flow system.Finally,the framework of the program is completed by using the Django module in the Python machine language,and the B/S(Browser/Server)mode is used in combination with the MySQL database to complete the Web-oriented application system.This application system can realize the closed-loop management of the whole process of power plant samples,realize dynamic,real-time and flexible control access,and improve the reliability,timeliness and traceability of sample detection.
