Description

Full touch system activation method and system thereof

Technical field

The present invention relates to the field of system activation technologies for portable electronic devices, and more particularly to a full touch system activation method and system thereof.

Background technique

With the development of touch technology, especially capacitive touch technology, touch sensor switches provide an alternative to electronic product button design. The touch sensor switch not only provides higher design flexibility and a more intuitive user interface than a mechanical switch, but is also more durable. Some portable electronic devices, such as personal electronic medical devices (electronic thermometers, electronic blood pressure monitors, etc.), electronic authentication devices (Ukey, etc.), personal consumer electronic products (MP3, MP4 players, etc.), are also increasingly used. The touch sensor switch acts as an interface for human-computer interaction.

When using a touch sensor switch as a human-computer interaction interface, portable electronic devices have different application requirements from traditional home appliances, automobile meters, computer peripherals, etc., including:

(1) Portable electronic devices require extremely low static and dynamic power consumption (low power consumption) to ensure long standby times. Portable electronic devices are mostly powered by batteries, and the longer the standby time required, the better. Some special applications such as electronic thermometers, Ukey, etc. are powered by button batteries that cannot be charged, and need to maintain standby time for several years. Extremely demanding.

(2) Need to avoid system error response (high reliability). Since the portable electronic device is frequently in contact with people (take it with you), it is easy to trigger the false trigger of the button when the touch button is used, and the system does not respond if the false trigger is required.

In order to comprehensively consider system reliability and low power consumption requirements, portable electronic devices need to set standby mode and working mode during system design. In standby mode, the system will not respond to external functional operations, and only respond to the system's request to switch from standby mode to normal operating mode, that is, the system "wakes up", and the system's function execution module will be turned off in this standby mode. Only the "wake-up" circuit is active and the system's power consumption is minimized. When the system "wakes up" successfully, it will enter the working mode. In this state, The system can respond to external functional requests, and all functional modules of the system are in working state, and the system power consumption is maximized. When the system receives an external standby command or does not perform a function operation for a long time, it will switch to standby mode, that is, the system "sleeps" to save dynamic power consumption. The system in standby mode does not respond to external functional operations. The design only needs to avoid the system's false "wake-up" to ensure high reliability of the system.

Traditional portable electronic devices generally use a hybrid button to achieve human-computer interaction, that is, the function buttons are implemented by capacitive touch buttons, and the "sleep" and "wake-up" buttons are implemented by mechanical buttons. Because the "sleep" and "wake up" buttons require high reliability, and the mechanical buttons need to be turned on or off by pressing the fingers, thereby implementing various functions such as enabling or turning off the control switches, requiring contact conditions and pressure conditions. At the same time, the button function can be realized at the same time. Compared with the touch button, only the contact condition can be started, and the reliability is higher. At the same time, the mechanical switch does not need to consume large static power consumption in the off state, and can satisfy the low Design requirements for power consumption. The function button is realized by the touch sensing method, which can avoid the wear problem of the mechanical button, has high design flexibility, is not easily affected by moisture, water, oil or dust, and can reduce system noise and improve reaction speed. The combination of mechanical buttons and touch buttons can meet the system requirements of high reliability and low power consumption, but it has the following disadvantages:

(1) The wear problem of the mechanical switch leads to poor long-term durability;

(2) The design flexibility is not high; because the structure of the mechanical buttons is complicated, it cannot be flexibly designed into a personalized button form like a touch button;

(3) It is easily affected by moisture, water, oil or dust, and there is system noise and slow reaction speed;

(4) Wake up using mechanical buttons, the function uses touch buttons, the overall design style is different, which is not conducive to users.

Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

Referring to FIG. 1, the full touch system activation method of the present invention includes:

S101. Query a state of a dedicated touch button in a standby mode;

S105. Switch the system from the active mode to the working mode according to the combined button state.

Referring again to FIG. 2, the full touch system activation method of the present invention includes:

S201, defining a dedicated touch button and a plurality of common touch buttons. As shown in FIG. 3, the present invention designs a dedicated touch button Key_0 and a plurality of common touch buttons Key_, Key_2, ..., Key_n-1, Key_n, wherein Dedicated touch buttons are used for "wake-up" or "hibernate" systems, and normal touch buttons are used to input touch button state matching information in the active mode or to respond to normal functions of the system in the operating mode;

S202. Query a state of a dedicated touch button in a standby mode;

S203, determining whether the dedicated touch button Key_0 is touched by a finger, and whether the time of continuous touch exceeds a preset duration, such as 2s, if yes, then executing S204; otherwise, executing S202;

S204, switching the system from the standby mode to the active mode;

S205, in the activation mode, sequentially query the status of the plurality of common touch buttons, and determine the combined button state according to the current state of the dedicated touch button and the state of the queried common touch button; It is obvious that the state of the dedicated touch button and the ordinary touch button can be preset in advance, for example, the state when the preset dedicated touch button and the normal touch button are touched by the finger is marked as the number 1, and the state when the touch is not touched is marked as the number 0. At the same time, a combination of a dedicated touch button and one or more ordinary touch buttons and a combined state may be defined, and the combined state may be a binary number or a graphic;

S206, calling a registration result stored by the key combination mode matching register, wherein the registration result is a binary number or a graphic;

S207, it is determined whether the state of the combined button is the same as the registration result, and if so, then executing S208, otherwise, executing S209;

S208, switching the system from the active mode to the working mode, that is, the system is successfully activated;

S209, returning the system from the active mode to the standby mode, and the system "sleeps".

It should be noted that the method of the present invention realizes the activation of the system by using the full touch mode of “dedicated touch button” + “normal touch button”, instead of the traditional hybrid button mode, the activation mode is added, and a system wakeup is provided. Time window condition. At the same time, in the active mode, the key combination mode matching provides a similar simple password conversion condition, which increases the number of conditions of the system "wake up", greatly reduces the probability of system false triggering, and ensures the reliability of the system. Moreover, the design of the "wake-up" or "hibernate" dedicated touch button makes the system only need to query a single touch button in the standby mode, the power consumption of the system can be very low, the number of charge and discharge of the button capacitor can be minimized, and the standby power consumption of the system Can also be reduced to the theoretical minimum.

Referring again to Figure 4a, a hardware circuit schematic for implementing the method of the present invention is provided. In this embodiment, a "wake-up" or "hibernate" dedicated touch button (Key_0) is set, and six common function touch buttons (Key_1 to 6), each of which has an inductive signal line, respectively named Sense0. ~6. The seven touch buttons share a driving signal DPP, and the touch button is designed to use a "national" shaped button graphic, that is, the sensing electrode and the driving electrode are connected by an interdigital structure to increase the mutual capacitance between the electrodes.

Sensing signal lines Sense0 ~ 6 via the analog switch S0 ~ 6 are respectively connected to the internal bus, and is connected to the programmable reference capacitance C _REF, the driving circuit for generating a complementary signal detecting stage where the positive and negative drive pulses of the drive pulse DPP DPN, DPP is connected to the drive electrode of the touch button, and the DPN is connected to the programmable reference capacitor C _REF . An internal initialization switch connects the internal bus to ground for initializing the internal bus voltage to 0V. The voltage comparator determines that the internal bus voltage is greater than or less than 0V to determine if a finger has touched the button. The voltage comparator output is sampled by the output sampling circuit and the result is output through the interface circuit. The internal low frequency oscillator is used to generate the clock signal required for the operation of the circuit, and the timing control circuit drives the internal module to coordinate the operation under the synchronization of the clock signal. The interface register is used to receive control commands from an external host to adjust the operating state of the circuit.

Referring again to Figure 4b, several register software interfaces related to the system "wake-up" in the interface register are listed. The timer count register is used to control the length of the pressing time of the "wake-up" or "sleep" dedicated touch button Key_0, finger touch When the button is pressed, the internal timer counter will be started. When the counter exceeds the register value, the counter overflows and the internal circuit will be switched to the active mode by the standby mode (only the Key_0 state is queried in this mode). The key combination mode matching register is used to determine whether the combined key mode matches. In the active mode, the internal timing control circuit controls the state of Key_1~6 in turn, and according to the current state of the dedicated touch button and the queried ordinary touch button. The state determines the state of the combined key, and then compares the state of the combined key with the registered result of the key combination mode matching register. If the result is the same, it indicates that the combined key mode matches, the system successfully "wakes up", if the mode does not match, the system "wakes up" fails. Re-hibernate. After "waking up" successfully, Key_1~6 are used for triggering common system functions. The trigger sensitivity is controlled by the reference capacitor configuration register. This register can adjust the sensitivity of the touch button trigger by adjusting the value of C _REF . It should be noted that, as described above, the registration result stored in the key combination pattern matching register may be a binary number or graphic as shown in FIG. 4b.

The frequency of the internal low-frequency oscillator can be adjusted by the register. In the standby mode, only the slow-query Key_0 state needs to be queried. At this time, the internal low-frequency oscillator can be set to have a very low frequency to reduce the standby power consumption. In the normal working mode, to improve the user's comfort and improve the system response speed, the frequency of the oscillator can be increased to improve the touch key query speed.

Accordingly, the present invention also provides a full touch system, as shown in FIG. 5, the system includes:

The setting module 10 is configured to set a dedicated touch button and a plurality of common touch buttons, as shown in FIG. 3;

The bus voltage is greater than or less than 0V, and it is determined in turn whether a finger touches the button, and the timer count register controls the pressing time of the dedicated touch button. When the finger touches the button, the timer count register will be started, when the count exceeds the register value. Counter overflow

In the full touch system of the present invention, a dedicated touch button and a plurality of common touch buttons are first set by the setting module 10, and then the state of the dedicated touch button is queried in the standby mode by the query module 11, and the determining module 11 determines whether the dedicated touch button is The duration of being touched and touched exceeds the preset duration. If it is exceeded, the notification switching module 16 switches the system from the standby mode to the active mode. Thereafter, in the active mode, the query module 11 sequentially queries the states of the plurality of common touch buttons. And the combination module 13 determines the combined button state according to the state of the dedicated touch button and the ordinary touch button, and then calls the registration result of the button combination pattern matching register 14 by the calling module 15 to determine whether the combined state and the registration result are the same, and if they are the same, notify the switching. The module 16 switches the system from the active mode to the active mode to complete the activation of the system. Otherwise, the switching module 16 is notified to switch the system from the active mode to the standby mode, and the system enters a "sleep" state.
