Referring to Fig. 4, in some embodiments, communication master device 100 uses I2C communication protocols with battery component 200
It is communicated, at this point, the first communication line 300 is clock signal line SCL.In addition, communication master device 100 is also logical by second
Letter circuit 400 is communicatively coupled with battery component 200, and the second communication line 400 is data-signal circuit SDA at this time.
In certain embodiments, using the GPIO of a support external interrupt, that is, " GPIO (EXTI) " in illustrating, connection
On the clock signal line (SCL) of I2C buses, for monitoring the low and high level situation on clock signal line (SCL).Example
Such as, the triggering mode of the external interrupt of GPIO can be set as rising edge and/or failing edge triggering, in this way, in communication process,
With the fluctuation of SCL signal, this external interrupt can constantly be triggered.Furthermore it is possible to record this using timer 20
Interval time between the external interrupt adjacent twice of GPIO, so as to current on monitoring clock signal line (SCL)
Level state and duration.
Also referring to 4 and Fig. 5, I2C communication protocols are the communication protocol for having twin wire universal serial bus, same using clock
The communication mode of step carries out data transmission.Wherein I2C buses include clock signal line SCL and data-signal circuit SDA, clock
For signal line SCL for ensureing that clock synchronizes, data-signal circuit SDA is used for transmission data.Sequence diagram as shown in Figure 5 can be with
Find out, the initial signal that communication master device 100 carries out data transmission with battery component 200 is kept in clock signal line SCL
Between high period, the level on data-signal circuit SDA is pulled low the level on i.e. data-signal circuit SDA by high level to low
It is to indicate the beginning of data transmission that level, which carries out saltus step,；Stop signal be between clock signal line SCL keeps high period,
Level on data-signal circuit SDA indicates the end of data transmission from low level to high level saltus step.And it is passed in data
Defeated period, each data transmitted in I2C buses are all corresponding with a clock pulses to synchronize control, due to logical
Letter main equipment 100 works in host mode i.e. I2C clock signal lines SCL and is controlled by communication master device 100, therefore, communication master
Equipment 100 can control the lasting variation of the level progress low and high level of clock signal line SCL.If communication master device 100 and electricity
The data transfer ends of pond component 200, then the level of clock signal line SCL can remain high level.Communication master device 100 is wanted
It is communicated with battery component 200, you can whether the level by detecting clock signal line SCL is in the state of low and high level variation
To judge whether battery component 200 is in idle condition.
Referring to Fig. 6, specifically, with communication master device 100 be unmanned plane and charger and current time unmanned plane is just sent out
It send and illustrates for data 0x55 to battery component 200.Wherein, predetermined level is high level.In unmanned plane transmission data
0x55 i.e. 01010101 to battery component 200 data transmission during, all corresponding one of each bit of transmission is complete
The clock pulses in period, therefore the level of unmanned aerial vehicle (UAV) control clock signal line SCL is from high level to low level or from low level
Persistently change to high level.At this point, charger to be communicated with battery component 400, then charger 400 starts control first
Request process, whether the level that clock signal line SCL is detected while control data process initiation is high level.If detection
Level to clock signal line SCL is the beginning timing of timer 20 that high level then triggers charger simultaneously.In data transmission
Period, since the level of clock signal line SCL persistently changes, the timing time of timer 20 is always less than predetermined period.Wherein,
During 0 timing of timer 2 is less than predetermined period, since the level of clock signal line SCL changes, and one is undergone
The clock pulses of a complete cycle changes so that the level of clock signal line SCL is back to high level, thus timer 20 again
It being reset, the time of timing resets, meanwhile, the control data process of charger is interrupted.After the data transfer ends, clock letter
The level of number circuit SCL is maintained high level, timer 20 be not reset so that 0 timing of timer 2 be more than or equal to it is predetermined
Period then can determine that battery component 200 is in idle condition at this time.In this way, the control data process of charger will continue to execute,
To obtain communication control power to realize the communication connection between charger and battery component 200.
In addition, if a certain moment battery component 200 is in idle condition, at this time if charger will be the same as battery component 200
Communication connection, then similarly, charger start control data process first, and start while control data process initiation and determine
When 20 timing of device.Since battery component 200 is in idle condition, the level of clock signal line SCL is maintained high always
Level, therefore, timer 20 will not be reset, and 0 timing of timer 2 can be more than or equal to predetermined period.In this way, in battery component
In the state that 200 is idle, the communication control method that embodiment of the present invention can also be used in communication master device 100 is detected and is obtained logical
Believe control.
It should be noted that the level due to clock signal line SCL may be due in low level or high level state
The factors such as pulse is unstable and there is a little fluctuation, therefore, what the level of clock signal line SCL remained high level expression is
The level that the level of clock signal line SCL is interpreted as the roads clock cable SCL more than or equal to a certain preset value is persistently kept
For high level state.For example, value of the high level of clock signal line SCL there is no fluctuation is 5V, then can incite somebody to action
Preset value is set as 4.5V.Therefore, as long as communication master device 100 detects that the level value of clock signal line SCL is more than or equal to
4.5V thinks that the level of clock signal line SCL is in high level state.In this way, even if the height electricity of clock signal line SCL
In the case of flat presence -0.5V~0.5V fluctuating errors, can also accurate judgement be carried out to the working condition of battery component 200.
In some embodiments, predetermined period is 1~3ms.In other words, the value of predetermined period can be 1ms,
1.5ms, 2ms, 2.3ms, 3ms are equivalent.If the value of predetermined period is too small, such as less than 1ms, then clock cable possibly is present at
When the level of road SCL is in variable condition, the case where duration of a certain high level is more than 1ms, battery pack can be led at this time
The erroneous judgement of the working condition of part 200.If the value of predetermined period is excessive, such as larger than 3ms, then 100 He of communication master device can be influenced
The speed of realization communication connection between battery component 200.The value range of predetermined period is arranged in 1~3ms, on the one hand
It can ensure the accurate judgement of the working condition of battery component 200, on the other hand not interfere with communication master device 100 and battery pack
The speed of communication connection between part 200.
In some embodiments, communication master device 100 is assisted with battery component 200 using the transmission of UART asynchronous serial datas
View is communicated, at this point, the first communication line 300 is to send signal line.In addition, communication master device 100 is also logical by second
Letter circuit 400 is communicatively coupled with battery component 200, and the second communication line 400 is to receive signal line at this time.
UART asynchronous serial data transport protocols are carried out data transmission using asynchronous communication means.UART asynchronous serial datas
The bus of transmission mode includes transmission signal line and receives signal line, and transmission signal line and reception signal line use each
From clock control respectively data transmission or receive process, it can be achieved that full-duplex communication.Similarly, with communication master device 100
To be illustrated for unmanned plane and charger and the positive transmission data 0x55 to battery component 200 of current time unmanned plane.Wherein,
Predetermined level is high level.During the data transmission of unmanned plane transmission data 0x55 i.e. 01010101 to battery component 200,
Send the clock pulses that each bit sent on signal line all corresponds to a complete cycle, therefore unmanned aerial vehicle (UAV) control
When send signal line level persistently change from high level to low level or from low level to high level.If at this point, charger
It to be communicated with battery component 400, then charger 400 starts control data process first, in control data process initiation
Whether the level of detection of transmitted signals circuit is high level simultaneously.If detecting, the level for sending signal line is same if being high level
When triggering charger timer 20 start timing.During data transmission, the level due to sending signal line persistently changes,
The timing time of timer 20 is always less than predetermined period.Wherein, during 0 timing of timer 2 is less than predetermined period, due to hair
The clock pulses sent the level of signal line to change, and undergo a complete cycle changes so that sending signal line
Level is back to high level again, thus timer 20 is reset, and time of timing resets, meanwhile, the control data of charger into
Journey is interrupted.After the data transfer ends, the level point for sending signal line is maintained high level, timer 20 be not reset from
And so that 0 timing of timer 2 is more than or equal to predetermined period, then can determine that battery component 200 is in idle condition at this time.In this way,
The control data process of charger will continue to execute, to obtain communication control power with realize charger and battery component 200 it
Between communication connection.
In addition, if a certain moment battery component 200 is in idle condition, if charger is logical with battery component 200 at this time
Believe online, then charger starts control data process first, and starts timer 20 while control data process initiation and count
When.Since battery component 200 is in idle condition, the level for sending signal line is maintained high level always, therefore fixed
When device 20 will not be reset, 0 timing of timer 2 can be more than or equal to predetermined period.In this way, the state left unused in battery component 200
Under, communication master device 100 can also be used above-mentioned same system control method and detect and obtain communication control power.
Similarly, since the level for sending signal line may be unstable due to pulse in low level or high level state
Etc. factors and there is a little fluctuation, therefore, send signal line level remain high level expression be send signal line
Level be more than or equal to a certain preset value be interpreted as send signal line level remain continuously high level state.
In some embodiments, communication master device 100 is assisted with battery component 200 using the transmission of UART asynchronous serial datas
View is communicated, other communication master devices 100 in addition to communication master device 100 are used in communication master device 100 and the battery
The data that battery component 200 is sent are abandoned when component 200 communicates.
It is appreciated that UART starts the communication master device 100 of control data process true using asynchronous communication means
When recognizing battery component 200 and being in idle condition, battery component 200 can be sent out to the communication master device 100 for starting control data process
Send response signal.And the response signal that battery component 200 is sent can be activated the communication master device 100 and not of control data process
Other communication master devices 100 for starting control data process receive, for example, charger startup control data process, and nobody
The not actuated control data process of machine.When charger confirms that battery component 200 is in idle condition, battery component 200 can be to charging
The control data process of device replys a response signal.The response signal can simultaneously be received by unmanned plane and charger.If
The unmanned plane for not initiating control data signal does not discard response signal, then the problem of causing logical miss.Because not sending out
Rise control request signal unmanned plane may be after receiving response signal a certain moment start control data process, at this time may be used
The response that the response signal received can be mistakenly considered to battery component 200 for this control data process feedback is believed
Number, to which unmanned plane is communicatively coupled with battery component 200.At this point, if the communication connection of charger and battery component 200 is also
It is not finished, then the communication between two communication master devices 100 and battery component 200 is carried out at the same time, that is, asking for logical miss occurs
Topic.
In addition, communication master device 100 is communicated with battery component 200 using UART asynchronous serial data transport protocols,
After communication master device 100 confirms that battery component 200 is in idle condition, also need to wait for just carrying out for a period of time logical with battery
Believe the communication connection of main equipment 100 and battery component 200.Because UART is using asynchronous communication means, in battery component
200 need to handle one response signal of ability feedback after the control data when receiving the control data of the transmission of communication master device 100.
Therefore, communication master device 100 needs the communication that could be initiated to battery component 200 next time of waiting for a period of time.
