Among the figure: 1, TCP/IP transport module; 2, GPRS transport module; 3, key control unit; 4, RS485 communication module; 5, RS232 communication module.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of large-scale photovoltaic power station group real time remote intelligent data transmission system shown in Figure 1; Has key control unit 3; Said key control unit 3 is made up of the AT89C51 single-chip microcomputer; These key control unit 3 one ends also are connected to the TCP/IP transport module 1 and GPRS transport module 2 that carries out communication with server, and the other end also is connected to the RS485 communication module 4 and the RS232 communication module 5 that is used to be provided with parameter to the communication of photovoltaic plant data acquisition equipment.
Particularly, the IP address of corresponding server need be set before GPRS transport module 2 and 1 communication of TCP/IP transport module, news that their meetings are attempted automatically and server connects; 4 pairs of photovoltaic plant the insides of RS485 communication module assembly, inverter etc. carry out the collection of data; Data processing module is to the data processing of packing; Can data be sent to the server of the network other end by the form of appointment through TCP/IP communication module 1 or GPRS communication module 2, realize data shared access.
This large-scale photovoltaic power station group real time remote intelligent data transmission system need not write the program of relevant communication protocol again according to the variation of scheme, only need do simple setting and get final product, has brought many convenience for maintenance yet, has saved R&D costs; The combination of GPRS and TCP/IP simultaneously makes more flexible with communicating by letter of server; Can formulate optimal case according to different situations; Can implement communication to the monitoring equipment of different brands difference in functionality, and the data that receive done Unified coding handle, can satisfy the photovoltaic plant demand; Reliable, easy for installation, intelligent degree is high, has good industrial application prospect.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
