针对传统测试实验平台的功能单一、操作复杂、扩展性差等问题,在CSY传感器实验台的基础上,开发基于虚拟仪器的温度参数测试系统,对温度参数的检测原理、检测方法进行了分析,并对测试系统硬件结构、测试系统软件设计和数据采集等关键技术进行了研究.结果表明:该系统可进行温度参数测试实验,测试系统交互性好,性价比高.“,”The problems of traditional experimental platform such as single function,complex operation,bad expansibility were described. The detecting system of temperature parameter based on virtual instrument was developed on the basis of CSY sensor test-bed,its principle and method of detecting temperature parameter were analyzed,and the key techniques such as hardware structure of detecting system,software design of detecting system,data acquisition were investigated. The experimental results show that the detecting experiment of temperature parameter is preceded in the detecting system,its interactive performance is good,and its performance-price ratio is high.
