摘要： 为了解决传统式固定协议配置的弊端，基于虚拟仪器平台，设计出解包处理数据对象功能。该设计大量使用LabVIEW函数结构、属性节点及变量,并且建立了不同模块的程序框图。用户可通过显示面板上加载、导入协议配置控件来完成灵活的协议配置，通过实验分析、公式回代验证该设计的可靠性；并对比传统式配置的编辑时间，验证该设计的时效性。应用结果表明,基于LabVIEW软件设计的数据协议灵活配置运行稳定可靠；在不同的通讯协议，该设计可方便快捷的实现相同数据的检测与采集，具有一定的实用性和推广价值。

Abstract: In order to solve the drawbacks of the traditional fixedprotocol configuration, this paper designed the function of data unpacking process based on the virtual instrument platform. The LabVIEW function structure, attribute nodes and variables are largely used in this paper and the programming diagrams of different modules were established. User can complete the protocol configuration flexibly through uploading and operating the configuration controllers on the display. Through experimental analysis and the formula substitution, we could validate the reliability of the design. Besides, by comparing the traditional configuration editing time, we could verify the efficiency of the design. The application results show that the flexible data protocol configuration based on LabVIEW can operate stably and reliably. For different communication protocols, the design can achieve the same convention detection and data collection, so this design is practical and it is worthwhile to promote.

 Key words: LabVIEW; protocol configuration; unpacking processing; CAN bus
