Specific embodiment
The feature and exemplary embodiment of various aspects of the invention is described more fully below.In following detailed description
In, many details are proposed, in order to provide complete understanding of the present invention.
In wind power generating set, the pitch control device of pitch-controlled system is set to hub side, and wheel hub is rotated with blade, variable pitch
Controller for receiving the order that master controller issues, open paddle, put away the oars by control blade, realize maximum power according to and stabilized (steady-state) speed
Function, and with master controller carry out data interaction；Cabin side is arranged in master controller, and cabin is not rotated with blade, master controller
For controlling wind power generating set starting, operation and stopping, and vane angle control command is handed down to pitch control device.
Communication topological diagram of the Fig. 1 between pitch control device provided in an embodiment of the present invention and master controller.Such as Fig. 1 institute
Show, to realize the data interaction between pitch control device 101 and master controller 102, conduction is provided between wheel hub and cabin
Slip ring 103.
Conducting slip ring 103 is made of slip-ring body, brush assembly of electric, the fixed components such as bracket and same core ball bearing, is capable of providing
The Mechatronic Systems of rotary power, data and signal without limitation, 360 degree rotation continuously or intermittently and multi-path.It will be conductive
Slip ring 103 is applied in wind power generating set, can be avoided conducting wire between cabin and wheel hub and sprains in rotary course.
Wire communication line 104 and wireless communication line 105, also referred to as wire channel and wireless communication are also shown in Fig. 1
Road.Wire communication line 104 based on conducting slip ring 103 mainly by PROFBUS DP (referred to as DP) agreement or
CanOpen agreement carries out data transmission, and conducting slip ring 103 will guarantee that contact is reliable in structure design, to guarantee wire channel
It is continuously switched on.
When actual motion, conducting slip ring 103 can transmit tens kinds of different electric signals, alternating current, height including high frequency
The alternating current of voltage, the alternating current of high current and small and weak DC small signal etc., and 103 interannular of conducting slip ring is apart from close, respectively
Kind signal generates mutually interference in transmission process, has severely impacted information transmission.
Due to the working characteristics and working principle of conducting slip ring 103 itself, the problem of poor contact and electromagnetic interference, is difficult to
Thoroughly solve.Therefore, for because of wind power generating set failure caused by poor contact and electromagnetic interference, can only by shut down come
Guarantee that wind power generating set safety needs to be immediately performed shutdown of putting away the oars after that is, master controller 102 detects that mistake occurs for communication,
Frequent shutdown will affect the generated energy of wind power generating set.
Wireless communication line 105 is primarily referred to as the communications such as bluetooth, wireless network, and wireless communication mode can be very
103 poor contact of conducting slip ring and electromagnetic interference problem are avoided well, therefore, when there is short trouble in wired communication mode,
It can switch to by communication, data interaction be carried out to master controller 102 and pitch control device 101, to realize wind-force
The redundancy running of generator.
But, on the one hand, self-test measures wire communication (such as DP) and interrupts, the data that pitch control device 101 receives
DP communication data is still come from, wireless communication data could be switched to completely after a period of time (for example, 500ms) that need to be delayed, herein
In period, the data that pitch control device 101 receives are 0, and pitch motor is out of service, and wind power generating set is in uncontrollable
State, even if switching to wireless communication data, and the control command that master controller 102 is sent in the 500ms time has changed
25 times (communication cycle of master controller 102 and pitch control device 101 is 20ms), the execution of pitch motor will appear jump, shadow
Ring the safe and stable operation of wind power generating set.
On the other hand, after detecting DP communication recovery, pitch control device 101 takes around the time of 20~40ms,
Data after DP communication recovery can be received, therefore, pitch control device 101 logic judgment begin to use DP communication data without
It is that still will appear the data received after wireless communication data and be 0, pitch motor is caused the case where minibreak occur.
Based on this, the embodiment of the present invention provides a kind of pitch-controlled system communication failure treating method and apparatus, storage medium, uses
The case where wire communication line fault between pitch control device 101 and master controller 102, using in the embodiment of the present invention
Technical solution can be improved the stability of communication data between pitch control device 101 and master controller 102.
Fig. 2 is the flow diagram of pitch-controlled system communication failure processing method provided by one embodiment of the present invention.Such as Fig. 2
Shown, which includes step 201 to step 203.
In step 201, while it being based on preset wire channel and preset wireless channel, transmits master controller and variable pitch
Operating condition interaction data between controller, wire channel are identical with the communication cycle of wireless channel.
Wherein, operating condition interaction data includes that the control blade sent from master controller to pitch control device opens paddle and puts away the oars
Vane angle control command, and the pitch motor revolving speed fed back from pitch control device to master controller and variable pitch angle etc..
Fig. 3 is the data transmission schematic diagram of wire channel provided by one embodiment of the present invention and wireless channel.In Fig. 3
Abscissa indicates the time, and ordinate indicates whether or not there is communication data (not indicating numerical values recited).
In the example of fig. 3, wire channel and wireless channel since 0 moment simultaneously, synchronize carry out data transmission, than
Such as, for some communication variables, master controller is 50 by the numerical value that DP communication is sent, and mutually in the same time, master controller passes through
The numerical value that wireless channel is sent is also 50.
In view of the transmission of data has periodically, need to send one by one, i.e., after previous frame data are sent completely,
Need just to start the transmission of next frame data after predetermined amount of time (such as 2ms), therefore, can make wire channel and
The communication cycle of wireless channel is identical, for example, master controller is become by the numerical value that DP communication is sent in next communication cycle
52, mutually in the same time, the numerical value that master controller is sent by wireless communication also becomes 52.
Fig. 4 be another embodiment of the present invention provides wire channel and wireless channel data transmit schematic diagram.In Fig. 4
Abscissa indicates the time, and ordinate indicates whether or not there is communication data and indicates numerical values recited.Figure 4, it is seen that in t0~t1
In period, during DP communication data interrupts, in wireless communication data still continuous transmission.
The Communication Control logic of current pitch-controlled system are as follows: the DP communication data in t0~t1 period occurs if detecting
After interruption, then channel switchover operation is executed within t0~t1 period, the data that pitch control device is received are communicated from DP
Data switch to wireless communication data.
Within t0~t1 period, since the data that pitch control device receives still come from DP communication data, and DP is logical
Letter data can become the value before 0 or holding because of channel interruption, and pitch motor is caused to will appear the pause of a period of time；And one
The data that master controller is sent in the denier period have changed, and also result in pitch motor after executing channel switchover operation
Execution jumps.
In step 202, if detecting, communication disruption, the letter that will be interrupted occur for wire channel or wireless channel
Road in the communications break during transmission data zero setting.
In one alternate embodiment, state-detection position, one frame one when due to data can be set in wire channel port
What frame was sent, when sending data every time, the signal of wire channel port just will appear heartbeat position (i.e. signal intensity), therefore, if
Detect that the signal of wire channel port does not occur heartbeat position within a predetermined period of time, it is determined that wire channel occurs in communication
It is disconnected.Similarly, state-detection position can also be set in wireless channel port, if detecting the signal of wireless channel port predetermined
Do not occur heartbeat position in period, it is determined that communication disruption occurs for wireless channel.
In one alternate embodiment, it also can use the communications status detection of master controller or pitch control device itself
Function, detects whether wire channel or wireless channel occur communication disruption, it is expected that communication channel one is interrupted in principle,
It can detected as early as possible.
In step 203, if synchronization, having one in the transmission data of wire channel and wireless channel is 0, then will be another
One is not 0 transmission data, as effective transmission data between current time master controller and pitch control device.
As noted previously, as the transmission data during the embodiment of the present invention breaks the channel interrupted in the communications are set
Zero, and the operating condition interaction data between master controller and pitch control device is based on wire channel simultaneously and wireless channel carries out, this
Even if the transmission data that the channel of communication disruption occurs for synchronization are zeroed out, but the biography of the channel of communication disruption does not occur for sample
Transmission of data is really normal.Therefore, the embodiment of the present invention from communication data compare angle, if synchronization wire channel and
Have in the transmission data of wireless channel one for 0, then by it is another be not 0 transmission data, as current time master controller and
Effective transmission data between pitch control device, the data in time receiving pitch control device are updated to the number in normal channel
According to.
With need to be implemented handover operation in the prior art, the technical solution in the embodiment of the present invention can be avoided the prior art
In channel switchover operation during, because the data that pitch control device receives still come from occur interrupt channel communication data,
Caused by pitch motor pause or jump, improve the stability of communication data between pitch control device and master controller,
It ensure that wind power generating set safe and stable operation.
Fig. 5 be another embodiment of the present invention provides pitch-controlled system communication failure processing method flow diagram.Fig. 5 with
Fig. 2 the difference is that, after the step 202 in Fig. 2, include the steps that 204 in Fig. 5.
In step 204, if synchronization, the transmission data of wire channel and wireless channel are equal and are not 0, then will
The transmission data of wire channel or wireless channel, as effective transmission between current time master controller and pitch control device
Data.
In this step, if the transmission data of synchronization wire channel and wireless channel it is equal and not be 0, illustrate
Wire channel and wireless channel are to disconnect, at this point it is possible to select the transmission data of wire channel or wireless channel, as working as
Effective transmission data between preceding moment master controller and pitch control device.When actual transmissions, usually with the transmission of wire channel
Based on data, supplemented by the transmission data of wireless channel.
Fig. 6 is the flow diagram for the pitch-controlled system communication failure processing method that further embodiment of this invention provides.Fig. 6 with
Fig. 2 the difference is that, after the step 202 in Fig. 2, include the steps that in Fig. 6 205 to step 207.
In step 205, if synchronization, the transmission data of wire channel and wireless channel are 0, then confirm wired letter
The state in road and wireless channel.
In this step, if the transmission data of synchronization wire channel and wireless channel are 0, illustrate there are two types of possibility
Situation, one is the states of wire channel and wireless channel to be in malfunction, and one is wire channel and wireless channels
State is normal, and actual transmissions data are 0.
In step 206, if the state of wire channel and wireless channel is in malfunction, to wind power generating set
Disorderly closedown operation is executed, wind power generating set is avoided to nonserviceable lower operation.
In step 207, if the state of wire channel and wireless channel is normal, current time main control is used as by 0
Effective transmission data between device and pitch control device.
Fig. 7 is the flow diagram for the pitch-controlled system communication failure processing method that yet another embodiment of the invention provides.Fig. 7 with
Fig. 2 the difference is that, after the step 202 in Fig. 2, include the steps that 208 in Fig. 6.
In a step 208, if detecting, the channel that communication disruption occurs has restored to communicate, and stops the zero setting to the channel
Operation, and restore the transmission data of the channel.
In order to facilitate the understanding of those skilled in the art, it illustrates below to the pitch-controlled system communication failure in the embodiment of the present invention
Reason method is described in detail.
Table 1 is the transmission schematic diagram data of DP communication and wireless communication based on the embodiment of the present invention.Wherein, in first row
Sequencing of serial number when indicating data receiver, secondary series indicates DP communication data, and third column indicate wireless communication data, the
The wireless communication data in DP communication data and third column in two column is the data executed in step 102 after zero-setting operation, the
Four column expressions take non-zero value to the DP communication data and wireless communication data at each moment, and the 5th column indicate that pitch control device is final
Reception data.
Table 1
| Serial number | DP communication data | Wireless communication data | Take non-zero value | Final reception value |
| 1 | 20 | 20 | 20 | 20 |
| 2 | 15 | 15 | 15 | 15 |
| 3 | 10 | 10 | 10 | 10 |
| 4 | 0 | 8 | 8 | 8 |
| 5 | 5 | 5 | 5 | 5 |
| 6 | 0 | 0 | 0 | 0 |
| 7 | -5 | -5 | -5 | -5 |
| 8 | 0 | -10 | -10 | -10 |
| 9 | -15 | 0 | -15 | -15 |
| 10 | -20 | -20 | -20 | -20 |
From table 1 it follows that the serial number 1-3 moment, DP communication and wireless communication state are normal, DP communication data and nothing
Line communication data is equal, and transmission data are 20, and therefore, taking 20 is the final reception value of pitch-controlled system.
4 moment of serial number, DP communication are interrupted, and data zero setting is transmitted, and wireless communication state is normal, and transmission data value is 8,
Therefore, taking 8 is the final reception value of pitch-controlled system.
At 5 moment of serial number, DP communication and wireless communication state are normal, and DP communication data and wireless communication data are equal, pass
Transmission of data is 5, and therefore, taking 5 is the final reception value of pitch-controlled system.
6 moment of serial number, DP communication data and wireless communication data are 0, need to confirm wire channel and wireless communication at this time
The state in road executes failure to wind power generating set and stops if the state of wire channel and wireless channel is in malfunction
Machine operation；If the state of wire channel and wireless channel is normal, illustrates DP communication data and wireless communication data is 0,
Taking 0 is the final reception value of pitch-controlled system.
At 7 moment of serial number, DP communication and wireless communication state are normal, and DP communication data and wireless communication data are equal, pass
Transmission of data is -5, and therefore, taking -5 is the final reception value of pitch-controlled system.
8 moment of serial number, DP communication interrupt, transmit data zero setting, wireless communication state is normal, transmit data value for-
10, therefore, taking -10 is the final reception value of pitch-controlled system.
At 9 moment of serial number, DP communications status is normal, and transmission data are -15, and wireless communication is interrupted, and transmits data zero setting,
Therefore, taking -15 is the final reception value of pitch-controlled system.
At 10 moment of serial number, DP communication and wireless communication state are normal, and DP communication data and wireless communication data are equal, pass
Transmission of data is -20, and therefore, taking -20 is the final reception value of pitch-controlled system.
In terms of the numerical value eventually received from pitch-controlled system, final reception value is completely the same with initial data, be not in compared with
The empty data of long period, to realize the instant seamless switching to DP communication data and wireless communication data.
Fig. 8 is during given sinusoidal velocity provided in an embodiment of the present invention controls pitch motor operation, to disconnect and restore DP
The motor operation curve of communication.Wherein, abscissa is the time, curve 801 be given sinusoidal velocity profile (frequency 0.1Hz,
Amplitude is 3 °/s), curve 802 is the angle value change curve for the pitch-controlled system that DP communications reception arrives, and curve 803 is wireless communication
