Design of Portable Power Quality Detection Device Based on DSP+ARM

Inhalt:
The requirements for data processing capability, operation efficiency and safe operation of portable power quality detection devices are getting higher and higher, and traditional power quality detection devices based on single-core ARM and DSP can no longer meet the requirements. Design the scheme of DSP and ARM dual-core portable power quality detection device. The DSP core is responsible for completing the collection of power quality data and the storage of the computing core; the ARM core is responsible for completing the display of power quality data and sending it to the host computer; the SYSLINK module is responsible for Complete the data transmission between the DSP core and the ARM core; on this basis, the rapid update of the voltage/current RMS method is used to improve the data detection accuracy, and the big data technology is used to improve the accuracy of the state monitoring of power quality information. [Result] The hardware and software design of portable power quality detection device was completed. The accuracy, efficiency and feasibility of the device are verified by testing parameter accuracy test, data processing ability test and dynamic power quality testing test.
