基于Modbus／TCP的低成本网关设计

摘要

The existing low voltage electrical products almost use the Modbus interface,which restrains the extensive use of gateway products for the ending user in intelligent grid.This paper proposed a design of gateway based on Modbus/TCP protocol.The test results show that the gateway designed can accomplish the corresponding conversion function,and reduce the performance requirement of protocol processing unit,the system design cost,and the software design difficulty.%现有低压电器产品运用的通信接口多为Modbus接口，限制了网关产品在智能电网中的广泛应用。提出了一种基于Modbus ／TCP的网关设计方案。测试结果表明，设计的网关能完成相应转换功能，减少了对协议转换处理芯片的性能要求，降低了整个系统的设计成本及软件设计难度。
