【Abstract】 To meet the increasing demands for data throughput, high integration, and flexibility in multi-device measurement and control systems, a system based on Modbus UDP protocol and FPGA was designed.The system comprised two subsystems, an upper computer subsystem and a lower computer subsystem, which communicated via the Modbus UDP protocol.The lower computer subsystem took FPGA as its core, with a bus architecture and modular program design that ensured the flexibility of system upgrades and communication reliability.The upper computer subsystem software, integrated with automated measurement and control functions, was based on a PC platform, modeling and displaying collected data as well as managing it.Experimental results indicate that the hardware communication rate meets standards, system communication is stable and reliable, and automated mea-surement works normally.This system realizes a highly integrated, easily maintained, readily upgradable, and high-speed communication measurement and control system with low overhead and cost, providing a viable solution for multi-device measurement and control systems.更多还原
