摘　　要：农业机械中所用的风机因作业的不同,对其性能要求也不相同。农用风机的性能对农业生产的经济性和安全性具有重要影响。传统风机性能测试多采用分离仪表,人工读取数值,存在测试周期长、工作效率低以及难以保证测量精度等问题。为此,以虚拟仪器技术为平台,构建风机性能测试系统;利用LabVIEW强大的数据处理和显示功能,通过对风机状态性能参数的显示和报警,实现对风机性能的测定;并介绍了系统的硬件结构和软件模块的设计。该系统设计为农用风机性能测试提供了一个新的途径。In agricultural machinery because the agricultural fan has different work, it is not the same as its performance requirement. The performance of agricultural fan has an important impact on the economics and security of agricultural production. There are some problems like as using separate instruments, reading numerical value by person, long testing cycle and low efficiency in Fan Performance Test. Aiming at these problems, Fan Performance Test System based on virtual instrument technology platform is designed. This article uses LabVIEW having a powerful data processing and display function to test the performance of fan by displaying and alarming the performance parameters. And it introduces the design of hardware architecture and software module. The system design provides a new approach for fan performance testing .
