汽车发动机性能试验台监控系统设计

The design of a monitoring-control system for use with an engine performance test-bed

介绍了由RS485总线组成的分布式汽车发动机性能参数测试系统的设计。对组成该系统的现场采集单元、通信网络单元、系统管理单元进行了分析与阐述。经现场实验验证,该分布式测控系统具有数据测量准确可靠,可扩展性强,性价比高,维护方便等特点。

This paper presents the design of an engine performance testing system consisting of a distributed monitoring network based on the RS485 bus. The paper makes an analysis of the essential parts of the system consisting of data acquisition unit, communication network unit and system management unit along with the description of them. The practical application indicates that system is not only reliable and easy to maintenance, but also low- cost and high -performance.
