FCV低温冷起动试验数据采集系统的开发

Development of data acquisition system for freezing start test of fuel cell vehicle

为满足燃料电池汽车低温冷起动试验评价需要,基于LabVIEW开发专门的数据采集系统,满足测试参数同步测量、显示和存储的需要。简要描述开发工具、采集仪器设备和开发过程,介绍数据采集系统的功能和实现方式。以某款客车为例,进行冷起动试验,使用开发的数据采集系统采集低温冷起动的性能参数。测试结果表明:所的开发软件高效方便,可满足试验需要。

In order to meet the evaluation needing of fuel cell vehicles start test at low temperature,a special data acquisition system based on LabVIEW was developed to meet the requirements of synchronous measurement,display and storage of test data.Based on a brief description of development tools,acquisition equipment and development process,the functions and implementation of data acquisition system were introduced in detail.A fuel cell bus was taken to conduct the freezing start test to prove software performance,the data acquisition system was used to collect the related data in the test.The results showed that the developed software could fully meet the test requirements with higher efficiency and convenience.
