In prior art, the staff links together wind power frequency converter and PC by the mode that connects wire, and apart from can only be 2～3 meters left and right, if the very growing way that wire is done must have influence on the quality of communication signal.In case the phenomenons such as wind power frequency converter bursts can not guarantee staff's safety, and wind power frequency converter work the time can be dispersed to the external world strong radiation, the staff be in for a long time be unfavorable under this environment healthy.
When the field service engineer keeps in repair blower fan, need to carry a lot of Heavy-duty Tools and arrive the arduous wind field of environment, suffer untold misery concerning the field service engineer.In addition, the field service engineer needs walking to go up a hill, and removes to debug blower fan, and the spacing between blower fan and blower fan is very large, must carry debugging frequency converter notebook computer, and bearing a heavy burden increases greatly.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of frequency converter with wireless communication function, especially is convenient to long-range machine of the on-the-spot wind power frequency converter of wind power generation, the off-grid of shutting down, be incorporated into the power networks are controlled and safety debugging simply and easily.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of frequency converter with wireless communication function, its Main Control Tank is provided with light signal sending module and optical signal receiving module, and described frequency converter also comprises optical fiber/485 modular converters, wireless WIFI transmitter module and wireless WIFI receiver module;
Described light signal sending module is connected with the light signal input of described optical fiber/485 modular converters, described optical signal receiving module is connected with the light signal output end of described optical fiber/485 modular converters, described wireless WIFI transmitter module is connected with 485 signal output parts of described optical fiber/485 modular converters, and described wireless WIFI receiver module is connected with 485 signal input parts of described optical fiber/485 modular converters.
The utility model can also adopt following technical measures:
Described optical fiber/485 modular converters, described wireless WIFI transmitter module and described wireless WIFI receiver module are connected with the Switching Power Supply output of described frequency converter respectively.
The network that described wireless WIFI transmitter module and described wireless WIFI receiver module and extraneous communication are adopted is 802.11b/g.
Advantage and the good effect that the utlity model has are: pass through technique scheme, the staff can be centered by frequency converter, has an area of any place in 100 meters scopes and uses the equipment such as mobile phone with the WIFI function, computer, ipad frequency converter to be debugged, operated and the relevant action such as monitoring.And a WIFI terminal can be controlled tens even up to a hundred frequency converters.Not only the process of convenient debugging, also can carry out Long-distance Control to blower fan.Through the conversion of switch, also can be by the long-range research and development centre that is connected in the Internet, so research staff's remote assistance on-site service personnel together participates in the issue handling of frequency converter.The utlity model has simple in structure, easy to connect, with low cost, stable performance and security performance advantages of higher.

Embodiment
As shown in Figure 1, the utility model provides a kind of frequency converter with wireless communication function, its Main Control Tank is provided with light signal sending module 1 and optical signal receiving module 2, and frequency converter also comprises optical fiber/485 modular converters 3, wireless WIFI transmitter module 4 and wireless WIFI receiver module 5;
Light signal sending module 1 is connected with the light signal input of optical fiber/485 modular converters 3, optical signal receiving module 2 is connected with the light signal output end of optical fiber/485 modular converters 3, wireless WIFI transmitter module 4 is connected with 485 signal output parts of optical fiber/485 modular converters 3, and wireless WIFI receiver module 5 is connected with 485 signal input parts of optical fiber/485 modular converters 3.
Optical fiber/485 modular converters 3, wireless WIFI transmitter module 4 and wireless WIFI receiver module 5 are connected with the Switching Power Supply output of frequency converter respectively.
Wireless WIFI transmitter module 4 and wireless WIFI receiver module 5 are 802.11b/g with the network that extraneous communication is adopted.
In regulator control system as shown in Figure 2, the course of work of this example is: light signal sending module 1 imports light signal into optical fiber/485 modular converters 3, and with light signal convert to 485 bus signals by 485 bus transfer to wireless WIFI transmitter module 4, wireless WIFI transmitter module 4 is through the decoding coding, 485 bus signals are converted to the WIFI signal with certain frequency, and this WIFI signal is sent.
