基于LabVIEW的重力仪仿真与测试系统设计

介绍基于LabVIEW的虚拟重力仪的设计，它是由数据采集卡采集外部信号，通过软件编程实现仪器的显示及测量等功能。该虚拟重力仪主要由数据采集、数字滤波、参数测量、频谱分析、功率谱分析和波形存储及读取模块组成，具有传统仪器所没有的许多优点，如能保存波形及测量结果、成本低廉，可以根据需要进行功能拓展等。实验证明，该虚拟重力仪运行可靠、性能良好和结果正确。

Simulation and Test System of Gravimeter Based on LabVIEW

The design of LabVIEW-based virtual gravimeter is introduced, whose external signal is collected by the data acquisition card and the display and measurement functions are implemented through software programming. The virtual gravimeter is consisted of data acquisition, digital filtering, parameter measurement, spectrum analysis, power spectrum analysis, waveform storage and reading modules, which also has many advantages such as the waveform and measurement results can be saved, low cost, function can be expanded as needed and so on. Experiments show that the virtual gravimeter has reliable operation, good performance and correct results.
