摘　　要：针对目前热动元件产品性能的测试还停留在全程人工测试的阶段,为提高热动元件产品的检测效率,设计了一种基于RS485总线的分布式监控测试系统。该系统硬件以STC单片机作为处理中心,利用温度传感器DS18B20和光栅测微传感器构建了系统的测试节点,以采集热动元件所处的测试温度和相应推杆位移;利用RS485总线技术构建了系统的网络通信架构,实现了多个产品同时测试。上位机软件基于.Net平台,数据库采用SQL2000,利用开源控件Zedgraph实时绘制出热动元件所处的测试温度和相应推杆位移在测试过程中的变化曲线,方便了测试人员对测试现场的掌控和对产品合格与否的判断。研究结果表明,该系统经过实际应用各项指标符合要求,实现了对热动元件产品的有效管理和性能参数的实时采集、显示、存储,实时描绘的曲线变化灵敏,系统运行稳定。Aiming at improving the test efficiency of thermal components product whose testing still stays in the manual phase, a distributed monitor system was designed based on RS485 bus. The STC microcomputer was used as the processing center of Hardware, the datas of tem- perature and hight were collected by the testing node of the system which was established with temperature sensor DS18B20 and grating sen- sor, multiple products can be tested at the same time as communication network structure of system was builded with RS485 bus technology. The host computer was based on . Net and SQL2000, the real time curve was drawed of the important parameters with Zedgraph which is a open source control so that the testing process can be controlled. The results indicate that the system meets the requirements and has many advantages, efficiency-improve can be achieved.
