Abstract: Based on the theory of cloud computing, a new technology system of virtual factory was proposed aiming at the chemical process. The key technologies were discussed and existing resources were virtualized as services. Three-dimensional environments were developed using virtual reality technology to simulate the real process in chemical industry. The case study of virtual factory for an ethylene glycol showed that the system has the scalability and openness. Process can be simulated quickly. Also the developed system can provide effective support for the simulated operation of the plant.

Key words: virtual reality, cloud computing, ethylene glycol, simulation system

摘要： 作为后超算时代计算服务的主流服务模式，云计算为制造业的资源整合利用创造了全新的服务平台。本文以已有的云计算理论为基础，针对化工过程的特点，提出了基于云计算的虚拟工厂技术体系，通过对关键技术的讨论，有效地将已有的资源虚拟化为服务，并通过虚拟现实技术建立三维云端模拟企业现场环境，增强了用户对现场操作的实际体验。基于云计算和虚拟现实技术建立的乙二醇虚拟工厂表明，系统具有扩展性和开放性，可以快速实现过程的仿真，为工厂的模拟操作提供有效的支持。
