Abstract: In order to establish the centralized monitoring capability of the intelligent engine bench, this article introduced the communication protocols such as the remote terminal unit and the user datagram protocol, and discussed and analyzed the advantages and disadvantages of various communication protocols. Based on the signal types in the engine bench, a centralized monitoring system with transmission control protocol/internet protocol as the unified interface was designed. The system transmited the network camera, bench temperature and pressure and other sensor signals and the information of the bench auxiliary equipment to the centralized monitoring system, realized the efficient and stable data transmission of the engine bench centralized monitoring system, and provided guidance for a smart laboratory and centralized monitoring system. etc.

Key words: Centralized monitoring system; Intelligent; Engine bench; Communication protocol

摘要： 为建立智能化发动机台架的集中监控能力，文章介绍了远程终端单元、用户数据报协 议等通讯协议，讨论并分析了各种通讯协议之间的优缺点。基于发动机台架中的信号类型， 设计了以传输控制协议/网际协议为统一接口的集中监控系统。该系统将网络摄像头、台架温 度和压力等传感器信号及台架辅助设备的信息传输到集中监控系统，实现了发动机台架集中 监控系统高效、稳定的数据传输，为智慧试验室及集中监控系统等提供了指导。
