Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is a kind of triggering judgment method flow chart based on multi-channel data disclosed in this implementation, tool
Body includes the following steps：
S101：Determine the corresponding multiple sensor electrodes of target trigger condition；
The target trigger condition is the trigger condition under preset specific operation, such as：Kick triggers item
Part, gripping action trigger condition, foot-up action triggers condition etc..After target trigger condition is set, target trigger condition is set
Corresponding multiple sensor electrodes, that is, there are one-to-many correspondences between target trigger condition and multiple sensor electrodes.
It should be noted that the corresponding multiple sensor electrodes of target trigger condition refer specifically to：Target trigger condition corresponds to
More than one sensor electrode.The quantity of the corresponding sensor electrode of different trigger conditions is different, and e.g., trigger condition 1 corresponds to two
A sensor electrode, trigger condition 2 correspond to three sensor electrodes.
Each sensor electrode corresponds to a channel, and a sensor can detect the data of multiple electrodes.
S102：When each sensor electrode meets corresponding trigger condition, each sensing is judged respectively
Whether variation tendency of the device electrode within the triggering duration accordingly be in corresponding preset range；If so, S103 is executed, if
It is no, it returns and executes S102；
It should be noted that according to actual needs, can set when corresponding some sensor electricity of target trigger condition
Whether pole is judged as variation tendency of the sensor electrode within the triggering duration accordingly after meeting corresponding trigger condition
In corresponding preset range.
Judge sensor electrode whether meet corresponding trigger condition method can for it is existing it is single pass triggering sentence
Disconnected method.
Preferably, further include in S102 foregoing description methods：

Include the variation tendency of sensor electrode data in different time sections when meeting trigger condition.
It should be noted that the variation tendency of data is pre- in different time sections when meeting trigger condition for sensor electrode
It is first stored in processor, and the real-time number that sensor electrode obtains in each data collection cycle within the triggering duration
In the processor according to fragmented storage, the real time data in each data collection cycle is stored as one section.
In order to reduce the EMS memory occupation amount in processor, the corresponding data of target trigger condition having been carried out are deleted,
It is always the current data for carrying out triggering judgement to make the data of fragmented storage in processor.
Variation tendency of the sensor electrode within the triggering duration accordingly is that sensor electrode is held in corresponding triggering
The variation tendency of size of data in the continuous time, such as kick action, variation of the sensor electrode within the triggering duration accordingly
Trend is first to become larger to become smaller again.
S103：Calculate the beginning triggering moment in multiple sensor electrodes the latest and earliest beginning triggering moment

As for opening the kick of boot wish, need to use two sensor electrodes for being respectively arranged in bumper and underbody.
It is almost therefore Δ t simultaneously that two sensor electrodes, which start to recognize trigger action,startVery little, the threshold value of setting is also just very
It is small.Judge that this time difference can algorithmically avoid the false triggering of some special circumstances.Such as：Flow (can recognize when raining
To be a kind of trigger action) it is that underbody is flowed to by bumper.Sensor electrode 1 is arranged in bumper, and sensor electrode 2 is arranged in
Underbody.Since water is slowly to flow to underbody from bumper, sensor electrode 1 carves t1 and sensing at the beginning of recognizing trigger action
Device electrode 2 carves the difference DELTA t of t2 at the beginning of recognizing trigger actionstartObviously it is more than and opens the setting of boot wish trigger condition
The first preset value TS, it is unsatisfactory for trigger condition, to which from bumper to flow to underbody such case split for flow when avoiding raining
The false triggering of boot.
ΔtendPhysical significance be that multiple sensors recognize the time difference that extraneous trigger action terminates.It is acted on
And the false triggering of some special circumstances is avoided, while more accurately identifying the specific switch motion of user.
Mutual processing between multi-channel data, it is ensured that switching device adapts to more complicated external environment, more smart
Really identify complicated switch motion.
S105：Judge that multiple sensor electrodes meet the target trigger condition.
A kind of triggering judgment method based on multi-channel data, determines that target trigger condition is corresponding disclosed in the present embodiment
Multiple sensor electrodes first judge whether each sensor electrode meets corresponding trigger condition respectively, and item is triggered when all meeting
Indicate that each sensor electrode is effectively triggering when part, then by judging that each sensor electrode is touched accordingly respectively
The variation tendency in the duration is sent out whether in corresponding preset range, accurately identifies complicated switch motion, eliminates maloperation
Influence, finally calculate opening for beginning triggering moment in multiple sensor electrodes the latest and earliest beginning triggering moment
Begin moment difference, and calculates the end trigger moment in multiple sensor electrodes the latest and earliest end trigger moment
Finish time difference, when the start time difference is less than the first preset value and the finish time difference is less than the second preset value
When, it indicates that the trigger action that each sensor electrode detects has synchronism, avoids each sensor under off-design behaviour
The electrode caused false triggering problem when different time sections are triggered respectively, improve multi-channel data triggering judge it is accurate
Property.

If when time threshold, judging that the corresponding sensor electrode meets trigger condition.
It should be noted that can when the corresponding all the sensors electrode of target trigger condition enter triggering judge after
It goes to judge whether each sensor electrode meets corresponding trigger condition respectively again；Target trigger condition can not also be needed to correspond to
All the sensors electrode enter triggering judge after go to judge whether each sensor electrode meets corresponding triggering respectively again
Condition, that is, for each corresponding sensor electrode of target trigger condition, as long as enter triggering judge it may determine that
Whether meet corresponding trigger condition, other tactility apparatus electrodes need not be waited also to judge to judge whether to meet accordingly again into triggering
Trigger condition.
