Design of Testing System for Hydraulic Excavator Based on NI CompactRIO
Translated Abstract
In order to acquire the parameters of an excavator system synchronously in the course of its work,such as the pressure and flow rate of the hydraulic system,the displacements of hydraulic cylinders and the rotational angle of the upper body,a testing system for the excavator is built based on NI CompactRIO with the technology of virtual instrument. The system can be used to ac￣quire signals from different I/O modules synchronously with FPGA. For acquiring the SSI signal from an industrial encoder,the com￣munication protocol is written with LabVIEW and a high-speed bidirectional digital I/O module is used. The data acquired by Com￣pactRIO is sent to the principal computer through network shared variables,saved and displayed in real time in the principal comput￣er. The experiments show that the system runs stably under complex conditions.
