The software and hardware platform of the system is set up and the test analysis is carried out according to the original design scheme of ARM+FPGA. A new design scheme of simulation node networking is proposed.
The embedded distribution network reconfiguration experiment device adopts the modular design concept: introduces the hardware structure of the embedded operation module, the design principle and function characteristics of the related units, the design of PCB and the matters needing attention in EMC, the establishment of the Linux system development environment, the transplant of BootLoader for embedded operation module, the transplant of the embedded Linux kernel and the construction of the root file system. And develop, test, add the device driver module that is missing in the kernel, analyze the measurement mode of the single phase alternating current energy parameter and the hardware design structure of the data acquisition module, the principle of data acquisition and calculation, the architecture and the development characteristics of the core measurement chip 78M6613, and write the host test program in the C language under the Linux system. The SLIP protocol is used to test the main functions of the data acquisition module through the serial interface. It describes the hardware structure of the distribution network simulation node, the function principle and the hardware implementation of each unit, and the electrical connection of the distribution network simulation module between the nodes. The Modbus protocol and the TCP/IP protocol are briefly introduced, and the analog node base is analyzed.

Using VC++ to develop the software testing platform for the system on the PC host, the modules of the reconfigurable device are integrated and tested, the different distribution network systems are selected to restructure, and the network loss analysis and reliability analysis are completed.
This paper summarizes the work and problems encountered in the development and testing of the embeded distribution network reconfiguration simulation experiment platform, and points out the shortcomings of the platform and the direction for the improvement and upgrading in the future.
