Multi-channel real-time detection system based on multi-FPGA master-slave control : Multi-channel detection system based on LabVIEW

In the face of the detection of mechanical energy and electrical energy parameters of medium and large complex systems, it is mainly realized by customizing expensive integrated multi-FPGA boards, and it is difficult to adjust independently in the face of flexible measurement and control targets. This paper proposes a detection system based on master-slave communication between LabVIEW and multi-chip field programmable gate array FPGA. The system uses LabVIEW software to use SPI bus technology to achieve master-slave control of multiple FPGAs. On this set of equipment, three-phase voltage and harmonics on-line detection and human interaction design and testing are carried out. Experiments show that the accuracy of this multi-FPGA detection system can meet the current mainstream detection requirements, and the cost is low, it is easy to control, it can be expanded flexibly, and it can achieve the same accuracy as professional test instruments.
