Design of the Photovoltaic Monitoring System Based on Serial Port Server
Aiming at the problems existing in current market of photovoltaic (PV) monitoring systems, e.g., complexity of the system, badly organized software, slow speed of data processing and lack of system scalability, etc., the flexibly scalable PV monitoring scheme is proposed.The scheme is implemented with the serial port server as the kernel;object-oriented approach to describe the devices;multi-thread technology for processing data, and modular concept to layout the system.On the basis of this scheme, the PV monitoring system based on Modbus communication protocol is built, and the experiments of operation and extension are carried out in detail.The practical operation indicates that the system possesses advantages of high efficiency and stability, transplantable and flexible extension, etc.
