Embodiment
Core of the present invention is to provide a kind of method of distributed power station communication, and the method can realize the communication of distributed power station, can support various communication protocol, strong adaptability; Another core of the present invention is to provide a kind of system of distributed power station communication.
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1, the flow chart of the method for the distributed power station communication that Fig. 1 provides for the embodiment of the present invention; The method can comprise:
Step s100, receive the data that in distributed power station, various equipment sends;
Step s110, determine the communication protocol that described data are corresponding, and according to described communication protocol, configuration setting is carried out to the corresponding driver in communication link layer;
Wherein, extensive in order to ensure the function of communication system, strong adaptability, the communication protocol of the data separate of therefore each equipment transmission is likely different.Therefore, the communication protocol that data are corresponding to first be determined; Again because this system is in order to make communication protocol simple, reliable, easily debug; Therefore, often kind of communication protocol has the driver corresponded, and relevant configuration does not also need and communication protocol is carried out, but carries out configuration setting according to communication protocol to the corresponding driver in communication link layer by configuration module.
