If it is not, S42:Perform trouble shooting and/or prompting.
One embodiment is that the controller of the toothbrush is connected with fault checking module, after the switch of toothbrush is started, drives horse
Up to can not normally run, trial inspection judgement can be carried out by fault checking module, such as detection circuit whether path, short circuit, different
At least one therein such as normal region, and can also be shown by display screen, further, can also starting protection circuit journey
Sequence, prevents whole circuit from damaging.It is easy to user to confirm problem and processing as soon as possible with this, it is ensured that the stabilization of the toothbrush is used.
Reference picture 3, it is preferable that S80:Screen real-time output current further comprising the steps of:
S81:Set up current threshold;
S82:Judge whether the corresponding output current of each timing node is located in the current threshold, if so, collection should
The corresponding output current of timing node.
Because electric current is continuous, and because external factor etc. can cause portion of electrical current value abnormal, by setting up electric current
Threshold values, may filter that abnormal current value, eliminates influence of the abnormal current value to post-processing and the magnitude of voltage drawn, improves detection
Precision.And judge that the corresponding output current of each timing node is located in current threshold by controller, controller collection is every
The corresponding output current value of one timing node, and carry out judgement processing, controller be acquired processing draw it is corresponding accurately
Pressure value, when the output current value is not in current threshold, can directly be rejected, and the calculating essence of pressure value is improved with this
Degree.
Reference picture 4, it is preferable that S30:It is further comprising the steps of before the switch for starting toothbrush:
S10:Pressure data model is stored,
S20:Set up the mapping database of pressure data model and output current.
One embodiment is that toothbrush stores or updated mapping database in advance, and pressure data model therein is according to tooth
The pressure limit value that the multiple simulated experiment of brush is detected, and pressure limit value is carried out to be divided into uniform node.By right
Each pressure node draws the output current of corresponding drive motor, is used as mapping database.Controller is set directly to detect with this
The curent change of drive motor can draw corresponding pressure change, it is not necessary to extra detection means, more simple and convenient.
