摘要:

配電自動(dòng)化系統的不斷改造和提升,是建立在配電自動(dòng)化終端設備不斷發(fā)展的基礎上。配電自動(dòng)化遠方終端(DTU)裝置是配電自動(dòng)化系統中的基礎設備。從數據通信穩定的角度出發(fā)提出了將Modbus/TCP通信協(xié)議與STM32微處理器相結合的設計方案。介紹了系統的總體構架和Modbus/TCP的通信協(xié)議內容,設計了以太網(wǎng)電路接口。在嵌入式實(shí)時(shí)操作系統μC/OS-II上實(shí)現了基于Modbus/TCP的通信協(xié)議客戶(hù)機端和服務(wù)器端的通信。實(shí)驗結果表明,該配電自動(dòng)化遠方終端可靠的實(shí)現了數據信息的穩定傳輸。

Abstract:

The continuous reformation and upgrade of power distribution automation system are based on the constant development of its terminal equipment. DTU is the basic device in the power distribution automation system. This paper presents a design combined Modbus/TCP communication protocol and STM32 microprocessor from the perspective of data communication stability. This paper has introduced the overall framework of the system and the contents of Modbus/TCP communication protocol, and designed the Ethernet circuit interface. Under the embedded system, the operating system μC/OS-II achieved the data communication between the client and server based on Modbus/TCP communication protocol. The experiment shows that this Data Transfer Unit can reach the stability and reliability of data and information transmission.
