| Based on the upper supervisory system of wind farm as the background, the module of transmission and communication are designed for the realization of the supervisory data between upper and lower machines completely.Based on MODBUS TCP/IP application protocol,the module of communication give full consideration to the actual environment characteristics of wind farm.Considering the actual needs of wind farm,the module of communication contains the real-time communication and the transmission of batch data transmission.Real-time communication is achieved through the supervisory application of wind power in a controller under real-time monitoring parameters.The transmission of the batch date is what the historical operating parameters what has been saved in the lower machine is delivered.Industrial Ethernet protocol-Modbus/TCP is a Modbus message transmission protocol running on TCP/IP protocol stack, due to its open, simple, easy to understand and stable performance, it is became the Ethernet industrial communication standards.With the continuous expansion of the Modbus protocol, serial links, high-speed token network, Web Server, the TCP/IP and other key technologies was introduced into the Modbus protocol solutions and was applied to the industrial site.This paper discusses the process based on the realization of the MODBUS/TCP protocol communications applications, this communication applications in WINCE on a real-time operating system as the software platform. |
