基于TTP可靠通信的电机监控系统

Motor monitoring system based on TTP reliable communication

针对一般单通道通信系统存在信道堵塞和通信失败后仍继续工作造成的系统可靠性低的问题,设计一种基于TTP通信的三节点控制通信模型,采用双通道冗余传输,主要目的是防止数据堆积冲突、因通道损坏导致的数据丢失问题。将LabVIEW作为系统的上位机开发平台,对电机进行监测和控制。STM32作为系统的控制器,各节点之间的信息交换通过基于时间触发的通信系统完成,排除了事件触发的资源共享冲突问题,为系统提供了良好的安全性保证机制,使系统的可靠性和实时性得到保障。

Since the general signal-channel communication system has the problems of channel blockage and low system reliability caused by continued operation after communication failure,a three-node control and communication model based on TTP communication is designed.The main purpose of adopting the dual-channel redundant transmission is to prevent data stack collisions and the data loss caused by channel damage.The motor can be monitored and controlled by using the LabVIEW as the upper computer development platform of the system.The STM32 is taken as the controller of the system.The information exchange between nodes is completed by the time-triggered communication system,which can eliminate the event-triggered resource sharing conflicts,provide a good security guarantee mechanism for the system,and ensure the reliability and real-time performance of the system.
