Include following steps.
In step 201, obtain the running parameter of touch chip every predetermined period, this running parameter is several
The capacitance that word circuit obtains from each capacitance that analog circuit is sampled every predetermined period.
For capacitive touch screen, when user's not execution operation on contact panel, analog circuit can be sampled
Obtain the first capacitance, this first capacitance is more than electric capacity lower limit；When user executes behaviour on contact panel
When making, due to producing coupled capacitor, therefore, the capacitance of touch screen between the finger of user and contact panel
Can change, analog circuit can be sampled and be obtained the second capacitance, the second capacitance is more than the first capacitance,
And it is less than electric capacity higher limit.According to above-mentioned touch-control principle, analog chip can be spaced at predetermined time intervals to tactile
The capacitance touching screen is sampled, and determines whether to act on touch screen according to the capacitance that sampling obtains
Operation.Wherein, the duration of predetermined time interval is more than or equal to the duration of predetermined period.
When analog circuit lost efficacy, analog circuit can not sample capacitance, or, the electricity of analog sampling circuit
Capacitance can malfunction, and therefore, it can by analog sampling circuit being obtained with capacitance carrying out detection determining simulation
Whether circuit lost efficacy.
In the present embodiment, touch chip includes intervalometer and digital circuit, and digital circuit can be in intervalometer
Under control, obtain, every predetermined period, the capacitance that analog sampling circuit obtains, then execution step 202.
In step 202., detect whether capacitance belongs to predetermined interval by digital circuit.
Predetermined interval is that touch screen is in the interval that capacitance during normal condition is formed.Wherein, fate
Between minima can be the first capacitance when operation is not existed on contact panel, the maximum of predetermined interval
It can be the second capacitance when operation is existed on contact panel.
In step 203, when capacitance is not belonging to predetermined interval, touch chip is determined by digital circuit
Lost efficacy.
When capacitance is not belonging to predetermined interval, determine that this analog circuit lost efficacy, so that it is determined that touch chip is lost
Effect；When capacitance belongs to predetermined interval, determine that this analog circuit effectively, continues executing with step 201.
In step 204, when detecting that touch chip lost efficacy according to running parameter, by digital circuit pair

And the duration of this scheduled time slot is more than the duration of predetermined period.
Processing unit can record the last moment receiving heartbeat signal, with this moment for start time
Determine scheduled time slot, detect whether to receive heartbeat signal in this scheduled time slot；When in this scheduled time slot
When receiving heartbeat signal, determine that digital circuit is effective；When not receiving heartbeat signal in this scheduled time slot
When, determine that digital circuit lost efficacy.
The duration of scheduled time slot can be equal to the duration of predetermined period.Because heartbeat signal can in transmitting procedure
Can there is time delay, when due to transmission delay lead to processing unit be not received by predetermined period heart beating letter
Number when, processing unit can determine whether that digital circuit lost efficacy, thus leading to error in judgement, therefore, it can setting pre-
The duration of timing section is more than the duration of predetermined period.Such as, the duration of scheduled time slot can be predetermined period
Three times of duration.
In step 303, when detect in scheduled time slot, do not receive heartbeat signal when, single by processing
Unit determines that touch chip lost efficacy.

When determining that digital circuit lost efficacy, whole touch chip can be resetted.Right due to needing only to
Touch chip is resetted, without restarting terminal, it is possible to reduce the time that reset touch chip is consumed,
The reset efficiency to touch chip can be improved.Or,
Because the working power of digital circuit is digital power, i.e. the digital circuit in touch chip and simulation
The working power of circuit is different, therefore, when determining that digital circuit lost efficacy, can also pass through processing unit pair
Digital circuit executes the operation that power-off powers up again, completes the reset to digital circuit.Now, only to touch-control
Digital circuit in chip is resetted, and without the whole touch chip that resets, solves reset and entirely touches
The control chip required time consuming relatively long problem, has reached the reset effect improving touch chip further
The effect of rate.
In sum, the touch chip crash handling method that the disclosure provides, is detected whether by processing unit
Receive the heartbeat signal of digital circuit transmission in scheduled time slot, do not receive in scheduled time slot when detecting
During to heartbeat signal, determine that touch chip lost efficacy by processing unit, by processing unit, digital circuit is entered
Row resets, and can only the digital circuit in touch chip be resetted, without the whole touch-control that resets
Chip, solves the problems, such as that the whole touch chip of the reset required time consuming is relatively long, has reached one
Step improves the effect of the reset efficiency of touch chip.
