伺服阀产线的智能协议转换技术研究

Research on technology of intelligent protocol conversion forproduction line of servo valve

针对多源异构设备数据之间互联互通的实际需求,提出了一种多源数据智能协议转换技术。以数据协议为核心,将采集的信息来源对象化后导入协议解析数据库,归一化后,基于不同应用需求的重构协议,如OPC UA(OPC Unified Architecture),输出XML(Extensible Markup Language)文件或存储至服务器,最后将数据库接入到产线的数据集成管控系统进行数据分析和可视化展示。以民机伺服阀产线产品调试设备为研究对象,采集油源、测试台和试验箱等设备状态和运行参数,对提出的数据协议转换技术进行了验证。实验证明,所提出的方法实现了油源、测试台和试验箱等设备数据之间的互联互通,为多源异构设备数据采集的融合应用提供了基础。

In response to the practical requirements of interconnection among data from multiple heterogeneous devices,a multi-source data intelligent protocol conversion technology is proposed.With the data protocol as the core,the information collected is objectified and imported into a protocol parsing database.After normalization,protocols are reconstructed based on different application requirements,such as OPC UA,and output to XML files or stored on a server.Finally,the database is connected to the production line′s integrated control system for data analysis and visualization.Taking the civil aircraft servo valve production line product debugging equipment as the study subject,the states and operational parameters of equipment such as the oil supply source,test bench,and test box are collected.The proposed data protocol conversion technology is validated through experiments,demonstrating that the method achieves interconnection among data from the oil supply source,test bench,test box,and other devices.This provides a foundation for the integrated application of data collection from multiple heterogeneous devices.
