基于LabVIEW的多功能信号采集与多通道定时计数器/触发器的设计

随着虚拟仪器计数的发展,软件即设备的思想已然成为科研仪器设备需求的发展趋势。文中利用现有硬件平台,给出了一个基于LabVIEW的虚拟仪器的设计与实现方法。该虚拟仪器不仅可实现多达24路以上通道的同步、异步精确计数功能,还可用于完成可控交互的定时触发和信号采集,同时能对试验数据进行存储、显示和回放。试验证明,结合设备软件化理念和虚拟仪器的实现,该方法可大幅提高现有设备的利用率,节约科研成本。

Design of Multi-functional signal acquisition based on LabVIEW and multi-channel timing counter / trigger

With the development of virtual instrument count, the idea of software as a device has become the development trend of the research equipment needs. Using of existing hardware platform, the design and implementation methods based on LabVIEW virtual instrument are proposed. The virtual instrument can not only achieve up to 24 channels above channel synchronous and asynchronous accurate count function, and can also be used to complete the controlled interaction of timing trigger and signal acquisition, and storage, display and playback test data. The test proves that the combination of the device software concept and the realization of the virtual instrument, this method can significantly increase the utilization of existing equipment and save research costs.
