In order to achieve efficient management and take full advantage of the information produced by products in the period of usage maintenance and the ends, the concept and architecture of closed-loop product lifecycle management is introduced briefly. Based on that, plasma system is taken as a specific application example. The product life cycle information flow model is summed. The C-L PLM software for intelligent products is designed and realized. At last, an application is taken as an example, displaying the running state information of the key components of the probe measuring equipment.%为了实现产品的使用、维护乃至生命结束信息的高效管理和充分利用,在简要介绍闭环产品全生命周期管理(Closed-Loop Product Lifecycle Management, C-L PLM)概念、架构的基础上,以低温等离子体设备系统为具体应用示例,总结出了产品全生命周期信息流动模型。设计并实现了智能产品C-L PLM软件。最后,给出一个应用实例,显示探针测量仪设备运行时关键组件状态信息。
