Modbus协议在储能系统中的实现与应用

Application And Implementation of Modbus Protocol In Energy Storage System

Modbus协议是一个请求/应答协议,在工业自动化网络中应用较为广泛。本文主要阐述了Modbus协议在储能系统中的实现与应用,介绍了Modbus通信协议,描述了储能系统主从站Modbus通信协议、报文格式及实现流程,从地址域设置、功能码选择及其在微控制器上的实现,再到基于MCU的主从站软件设计,均作了详细论述。最后对该方法在工程应用中的实现及试验结果作了简要描述。本文的通信设计方法已在同里综合能源服务中心储能系统中应用,验证了Modbus协议在储能系统通信中具有良好的稳定性及正确性。

Modbus protocol is a request/reply protocol, which is widely used in industrial automation network. This article mainly expounds the Modbus protocol in the implementation and application of energy storage system, introduces the Modbus communication protocol, describes the Modbus communication protocol, message format, and the implementation process,from the address setting, the function code selection and the realization on the micro controller, to the design of master-slave station software based on MCU, are discussed in detail, Finnaly, the implementation of this method in engineering application and the test results are described briefly. The paper has applied this method to energy storage system in tongli comprehensive service center. And it is verified that Modbus protocol has good stability and correctness in energy storage system communication.
