Preferably, the controller is connected with status indicator lamp.
Preferably, the touchpad includes capacitance.
Preferably, edge strip disk is provided with around the touchpad, edge strip disk surrounds the touchpad of rectangular distribution.
Preferably, edge strip disk includes capacitance.
Preferably, the remote controler further includes impulse generator, transmitter and receiver, and transmitter and receiver are divided into
The touchpad both sides of rectangular distribution, impulse generator connect transmitter, and the energy of transmitter transmitting is coupled with receiver.
In the present embodiment, mutual inductance pattern is worked in after the power is turned on, can work independently per single touchpad, and only hand touches at this time
When touching any one touchpad, just there is corresponding action, it is desirable to be switched to self-inductance mode and need just cut by switch key function
It changes.9 touchpads are equivalent to a big touchpad in self-inductance mode.4 of this big touchpad and outside at this time
Edge strip disk works together, identifies different gestures.Mutual inductance pattern and the operation principle of self-inductance mode are to use capacitance touch
The principle of switch, the i.e. capacitance are converted into after current signal until feeding back to controller and executing straighforward operation by controller
Component constitute capacitor type touch switch.Finger touch/gesture induction makes touchpad, edge strip disk generate capacitance.
Wherein, entering self-inductance mode from mutual inductance pattern needs switch key to switch, this switch key can arbitrary touchpad/edge strip
Disk combination of two can also be separately to set password key.For self-inductance mode relative to mutual inductance pattern, MCU controllers are mostly all the way or several
It detects on road.
It is the difference by detection gesture in self-inductance mode come indicating on-off state, and using mutual volumetric method come real
Existing, 4 edge strip disks of a big touchpad and outside work together, are examined to the reduction of touchpad by detecting energy coupling
The close of human body is surveyed, human body is moved to human body close to partial electric-field makes the electric field between touchpad and edge strip disk reduce.Mutually electricity
Appearance method is more complicated than self-capacitance method, however can reduce the influence of parasitic capacitance, can also by increase generate electric field strength come
Improve sensitivity.
As shown in Figs. 1-2, the remote control method of the remote controler of the present embodiment, including it is operated in the touching telecontrol behaviour of mutual inductance pattern
Make method and the gesture induction remote control method for being operated in self-inductance mode, wherein

It touches, and generates current signal, as shown in fig. 7, after converted formation digital signal, with the number for judging that switch judges digital signal
Value whether be more than given threshold, if so, judge switch for " ON ", and feed back to controller execute corresponding touchpad correspondence it is distant
Control operation, if it is not, then judging switch for " OFF ", controller does not execute straighforward operation；
The self-inductance mode is：Electric field is arranged between multiple touchpads, finger is close to touchpad using impulse generator
The different gestures operated afterwards make touchpad generate the current signals of different powers, after converted formation digital signal, with judging to open
It closes and judges whether the number of digital signal is more than given threshold corresponding from different gestures, if so, switch is judged for " ON ", and
It feeds back to controller and executes the correspondence straighforward operation of respective threshold, if it is not, then judging switch for " OFF ", controller does not execute distant
Control operation；
Remote controler is set to be operated in mutual inductance pattern or self-inductance mode by switch key.
Preferably, the controller is MCU, and controller is connected with status indicator lamp.
Preferably, the touchpad includes capacitance, and capacitance is electrically connected with capacitance-current converter.

As shown in figure 3, the self-capacitance method total capacitance in mutual inductance pattern is the sum of parasitic capacitance and finger capacitance, parasitic capacitance
It is that fixation is present between touchpad and ground, when finger touches touchpad, capacitance generates on corresponding touchpad.Such as
Shown in Fig. 5, when finger touches touchpad, control pulse makes SW1 be closed, and SW2 is disconnected, and is charged to capacitance；Work as finger
It touches when leaving touchpad, control pulse makes SW1 disconnect, and SW2 is closed, and is discharged capacitance, electric current changes with time such as Fig. 6
It is shown.There are a generation current courses between the capacity and SW1 of capacitance and the switching frequency and voltage of SW2.I=F*C*V
(I is electric current, and F is switching frequency, and C is capacitance, and V is circuit voltage) later again quantifies current digital.Electric current is due to switch electricity
The continuous charge and discharge of capacitor in capacitor filter device and alternately change.The power circuit that the alternating current passes through connecting valve power-supply filter
It carries out smooth.Electric current is sent to current oscillator, and current oscillation frequency is directly proportional to electric current.The output of oscillator is sent to meter
Number device, counter calculate the umber of pulse in specified time.When ON/OFF judges that switch judges to judge that human hand is contacted with touchpad
The increase of capacitance.This is the variation of the capacitance measurement process by being periodically executed controller and measurement counter value to complete.
When finger close to touchpad then further out when, determine the process that whether opens/closes of switch, measure electricity at regular intervals
Hold.When finger leaves touchpad, by measure obtained count value be it is stable, when finger close to when, count value increases, when
When finger leaves again, count value is reduced to stationary value.Count value when by finger not close to touchpad is used as reference value, and will
Given threshold is calculated as the specified difference with the reference value.Judge that the decision of switch can be by checking whether actual count value surpasses
Given threshold is crossed simply to determine, and (OFF) is closed when the value is less than given threshold.Typically, it closes and determines also to want
The value is asked to be referred to as the specific quantity of lag less than given threshold one.The sensitivity adjustment of capacitor type touch switch can be by changing
Become threshold value to complete.The period of timing and average multiple count values are measured by change, it can be with regulating switch jitter suppression and anti-
Answer rate.
As shown in figure 4, the touchpad capacitance in self-inductance mode is generated by mutual volumetric method.Mutual volumetric method uses
Receiver, transmitter and impulse generator are configured.When pulse is sent to transmitter, energy is transmitted to by field coupling and is connect
Device is received, when the finger of people is close, partial electric-field is moved to human body, and the electric field between touchpad reduces.So as to cause electricity
The change of capacitance, different gestures correspond to different capacitances, so that the electric current count value that MCU controllers receive is also different.
It is different to the instruction of status indicator lamp.
The embodiment of the utility model is without being limited thereto, according to the above of the utility model, utilizes the general of this field
Logical technological know-how and customary means, under the premise of not departing from the utility model above-mentioned basic fundamental thought, the utility model may be used also
To make the modification, replacement or change of other diversified forms, all fall within the utility model rights protection scope.
