Abstract
The invention relates to a wireless signal transmission system, which is a system utilizing radio waves to transmit videos, audio frequencies, data and other signals. A wind generator comprises a plurality of parts, and a transmission system penetrates through each part, i.e. the transmission system is a nerve of a wind generation system, thus, the transmission system is a key part which is directly related to the working state, the generation amount and the safety of the wind generator. The wireless signal transmission system carries out data transmission between cabin wheel hubs of the wind generator. In the wireless signal transmission system, signals in the wheel hubs are mutually transmitted, and not any signal line is needed, so that various faults of wired transmission are reduced.
Description
Technical field
The present invention relates to a kind of novel control mode, a kind of specifically wireless transmission method of wheel hub internal control signal.
Background technique
Wind-driven generator inner hub and controller control at present, power line, safety chain signal etc. are all passed through slip ring and are got in the change slurry control cabinet in the wheel hub, realize the transmission of cabin and wheel hub power and signal.Can occur signaling line in this traditional transmission course and come off agingly, slip ring wearing and tearing are waste and old, potential problems such as staff's maintenance and repair difficulty when breaking down.When taking place, the most oar communication failures that become of runaway accident generation all cause by the slip ring bad connection.The gear-box leakage of oil causes oil-feed in the slip ring when serious, oil plays insulating effect attached to forming oil film between slip ring and the contact pin; Cause becoming the oar communication signal off and on; Cause master control cabinet control unit can't accept and the feedback processing overspeed signal, cause pitch-controlled system to stop, until driving; Owing to the in-built reason of slip ring, interruption and time-delay that also can priming signal phenomenons such as slip ring magnetic track and probe bad connection can appear.Because it is general all in the big remote place of wind that wind-driven generator is installed, and when related works such as needs maintenance and repair, wastes time and energy.Even if do not need various signaling lines to be connected in the present invention's wheel hub with the cabin, directly use wireless transmission, when unmanned, also can on certain hour and degree, continue safe operation when breaking down or select to shut down.
Summary of the invention
The present invention is directed to the difference of inner wire transmission of existing control wind-driven generator and wireless transmission, the datawire that wire transmission exists is mixed and disorderly, the collector ring carbon brush damages, and deficiencies such as maintenance difficult provide a kind of new control mode.Controlled in wireless controller cost is low, and transmission data distance need not router, is fit to large-scale promotion.
Technological scheme of the present invention is: because development board and GPRS terminal are used serial ports to carry out the exchange of data and realized the control function; So this application program to realize note transmission, receive, read relevant management function; Embedded GPRS wireless communication module is by cordless communication network; Form virtual private data network and transmit data, have advantages such as network coverage is wide, transmission is reliable, dilatancy is good, networking flexibility, the construction period is fast, operation cost is low.The construction cost of system is also very cheap; Central station is only acquired a station server and tie line; An embedded radio communication module is acquired at the terminal just can set up complete data acquistion and control system; In addition, embedded GPRS wireless communication module adopts transparent data transmission and protocol conversion, is well suited for the user and carries out secondary development and be applied in the different systems.GPRS can be applied to company intranet equally, and IP-based remote lan inserts, and makes wireless terminal become the extension of LAN.But common GPRS module is some narrow limitation in use, and it does not have embedded ICP/IP protocol stack, needs the user that the support of TCP/IP is provided; In other words, need in the upper-position unit SCM system that uses the GPRS module, embed TCP/IP, this is a complicacy and loaded down with trivial details work, sometimes even surpassed the workload of application itself.Based on the demand that a kind of simple and practical GPRS scheme in communication is provided; The author has developed embedded GPRS mobile radio telecommunications module; It is embedded ICP/IP protocol stack; Simplified Interface design, realized the transparent transmission of data between user terminal and server, made the user can use the GPRS technology easily and realize long-range wireless data transmission.
Concentrate to gather the data information of local wind motor, and mainly be to reach accurate position control through positioning control, speed ring will be realized following the tracks of fast, and electric current loop is realized the Fast Dynamic response.In servocontrol, master controller provides position command value at electric variable pitch, compares with position feedback; The output of position regulator is exactly the input of speed regulator; Carry out proportional integral, speed regulator output torque command value, with value of feedback relatively after; Difference is delivered in the torque controller; Output is exactly the torque current setting value, and, reaches the current-order vector control torque control and divide the records center of door controlled in wireless end communications module and wind-driven generator Co., Ltd mutual mutually on the spatial position of quadrature at the magnetic flux that is produced with magnetic pole; The wind power collecting terminal can guarantee the automatic detection of network path to concentrator one example, repairs automatically.
The invention has the beneficial effects as follows: the present invention is simple to operate; Become electrical signal through the sensor acquisition wind speed and direction and pass to control system; Control system is processed contrast to the signal of input at any time; Pass to control end through wireless network side, control centre handles the data of input, and wind-driven generator is carried out wireless transmission.

Accompanying drawing 2 hub design novel type figure of the present invention.
Embodiment
Specific embodiment of the present invention: carry out alternately through wireless protocols and wireless control terminal; Possess functions such as terminal inquiry, terminal configuration, telecontrol, software upgrading; Can be wind-driven generator simultaneously business monitoring, fault treatment etc. are provided, accomplish the integrated of concentrator and terminal wind power collecting terminal.The integrated installation of field engineering at concentrator and terminal wind power collecting terminal is accomplished in data capture, and is responsible for accomplishing the network uniting and adjustment of terminal wind power collecting terminal to concentrator (WSN) and concentrator to the wireless collection data center systems.Administrative staff can join new wireless monitor point in the existing network rapidly, need not lay network, increase equipment for newly-built transmission, realize the long distance wireless transmission easily.
