摘　　要：针对虚拟仪器动态响应时间评估需求,提出了虚拟仪器软件执行时间测试的新方法。为了实现软件执行时间测量,开发了Lab VIEW时间测量功能。通过执行过程的重复循环以及测量数据的统计分析,有效解决了程序执行时间短和Lab VIEW时间测量精度有限的问题。对虚拟仪器执行时间测试方法实验结果表明,新方法可用于虚拟仪器动态响应时间评估。Deal with the assess requirements for virtual instrumentation dynamic response time,This paper presents the new approach to the test and assessment of the software execution time in the virtual instrumentation.To determine the times of the VI software part execution,the Lab VIEW timer function is exploited.By repeating examined operations in a loop,and using statistical analysis to determine the time of a single operation,the question of very short time of the tested operations and the limited accuracy of the Lab VIEW timer is effectively solved.The experimental results show that virtual instrument execution time test new method can be used to evaluate the dynamic response time of virtual instrumentation.
