基于TwinCAT的主减速器试车台监测系统设计

Design of monitoring system for a main gearbox bench based on TwinCAT

针对某型号直升机主减速器试车台的信号采集与监测要求,设计了以Twin CAT为核心的试车台监测系统。采用CANopen与PROFIBUS-DP现场总线和Ether CAT总线构成二级分布式总线网络,实现对多种信号的数据采集;采用基于Twin CAT软PLC技术进行数据的处理、监测报警,并通过ADS通信与上位机人机接口(HMI)进行交互;基于.NET平台实现上位机用户管理、监测报警数据显示及历史数据查询等,使用Microsoft SQL Server 2008大型关系数据库实现数据管理。详细介绍了系统的设计与开发过程,现场应用表明,系统具有较好的稳定性和实时性。

Against the requirements of signal acquisition and monitoring of type X helicopter main gearbox bench ,the bench moni- toring system based on TwinCAT was designed. With EtherCAT and the fieldbus CANopen and PROFIBUS-DP, two distributed bus networks were constituted for a variety of signal ; the soft-PLC technology TwinCAT was used for data processing, monitoring and alarming, and communicated with HMI through ADS; HMI functions including user management, display of monitoring and a- larming data, inquiry of history data were realized based on. NET, and data management through the database Microsoft SQL Serv- er 2008. The design and development of the system was introduced detailed. Practice showed that the system had a good stability and real-time performance.
