Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application.

It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

Although the current electric assisted bicycle and instrument display system have adopted the method of starting with a password, the password input area is integrated in the existing password unlocking method, and one digit cannot be modified separately. Therefore, the user has high requirements for entering the password. The user can only start the system and unlock the electric assisted bicycle by entering the correct password once. However, when the user enters one of the digits incorrectly when entering the password, it is necessary to delete the entire password and then re-enter the password, which greatly reduces the convenience of the user starting the system.

Based on the above problems, the present application proposes a method for starting and controlling an instrument display system, which is applied to an instrument display system of an electric power-assisted bicycle. As shown in FIG1 , the instrument display system includes a button device 101, an instrument device 102 and a controller 103, wherein the button device 101 includes a button unit and a button circuit, the instrument device 102 includes a first power supply circuit, a second power supply circuit, a power-on circuit, an instrument display unit and an instrument microcontroller unit (Microcontroller Unit; MCU for short), and the controller 103 includes a controller microcontroller unit and a third power supply circuit, wherein the power-on circuit is respectively connected to the first power supply circuit, the second power supply circuit, the third power supply circuit and the MCU, the first power supply circuit is connected to the instrument display unit, the second power supply circuit is connected to the button circuit, and the third power supply circuit is connected to the controller MCU, and is used to respectively power the screen, the button, the controller and the instrument MCU after the instrument is turned on, the instrument MCU and the controller MCU are connected via a communication interface, and after the controller MCU receives a communication message sent by the instrument MCU indicating that the instrument password is successfully entered, it controls the electric power-assisted bicycle to unlock and start.

The key signal analysis unit, the call execution unit and the storage unit can be set in the instrument MCU of the above-mentioned instrument display system. The key unit receives the key signal, the key signal analysis unit analyzes the signal, and the call execution unit calls the corresponding array in the storage unit, and finally displays the call result on the display unit. By setting the input area and the confirmation area for the password input area, and setting the editable state and the locked state for the selected area of the input area, the key signal triggers different key instructions in different areas and states, and each area is independent of each other, so that each password can be entered and modified separately, thereby avoiding the problem of clearing all passwords and re-entering the password when an error is made in entering the password.

Next, the above-mentioned instrument display system startup control method is described. The method can be applied to the instrument display system of an electric power-assisted bicycle. As shown in FIG2 , the method includes:

S201: The key unit receives a first key input signal, a second key input signal, a third key input signal, and a fourth key input signal in sequence.

Optionally, the key unit may be arranged on a key device built into the instrument, and the user triggers each key to generate a corresponding key signal by pressing the key unit. The key input signal may be a key signal generated by the user pressing and received by the key unit.

Optionally, the instrument display system may include multiple key units, and the user may trigger a key input signal corresponding to each key unit by pressing different key units.

Optionally, the key input signal may include an identifier of the corresponding key unit. After receiving the key input signal, the instrument display system may identify the source of the key signal through the identifier corresponding to the key unit.

Exemplarily, the key unit can be as shown in Figure 3, including three keys, namely, a "plus" key, a "power" key and a "minus" key from left to right, and there can be three corresponding key signals, namely, a key signal corresponding to the "plus" key, a key signal corresponding to the "power" key, and a key signal corresponding to the "minus" key.

Optionally, the key unit sequentially receives a first key input signal, a second key input signal, a third key input signal and a fourth key input signal input by the user through the key unit, and the first key input signal and the third key input signal can be triggered by, for example, the "plus" key or the "minus" key in Figure 3, wherein the first key input signal can be used to determine the selected area, the third key input signal can be used to determine the display number of the selected area and the color of the display unit, and the second key input signal and the fourth key input signal can be triggered by, for example, the "power" key in Figure 3 to change the state of the selected area.

S202: The key signal analysis unit analyzes the attributes of each key input signal in sequence, wherein the attributes of each key input signal include: the source of the signal and the number of times the signal is triggered.

Optionally, the key signal analysis unit may be used to analyze properties of the key signal, thereby identifying the triggering operation performed by the user on each key.

Optionally, the number of times the signal appears may be the number of times key input signals from the same source appear, and the source of the signal may indicate the key unit corresponding to the input signal.

Optionally, the attributes of the key input signal may also include signal duration. The signal duration can be divided into "long press", "short press", "continuous double click", and "invalid" according to the length of time the key is triggered or pressed. The password input is only valid when the key is "short pressed". For example, when the pressing time is <20ms, it can be regarded as an invalid operation, when 20ms<pressing time<300ms, it can be regarded as a short press operation, and when the pressing time is >1s, it can be regarded as a long press operation. The long press operation can be used as a power-on operation, for example.

S203: calling the execution unit to determine the selected area among the multiple input areas according to the attribute of the first key input signal, and calling the color array stored in the storage unit to display corresponding colors on the selected area and the unselected area of the display unit.

Optionally, the display unit may be a password input interface, and the display unit may include multiple password input areas. Exemplarily, the interface of the display unit may be as shown in FIG. 3 , and the password input areas are: area 1, area 2, area 3 and area 4, and area 5 is a confirmation area.

Optionally, a color array may be stored in the storage unit, and the color array may include, for example, a foreground color and a background color, wherein the foreground color and the background color of the selected area may be yellow and white, respectively, and the foreground color and the background color of the unselected area may be blue and black, respectively. This is just an example, and the specific color setting is not limited in this application.

Exemplarily, after calling the execution unit to determine that the selected area is area 1 based on the attributes of the first key input signal, the foreground color and background color of area 1 can be set to black and white, respectively, and the foreground color and background color of area 2, area 3, and area 4 can be set to blue and gray. By setting different colors for the selected area and the unselected area, the user can more easily identify the currently selected area, thereby improving the convenience of user operation.

Optionally, the input area of the display unit may include an unselected area and a selected area. The selected area may be an area where the user inputs or modifies numbers, and the unselected area may be an area where the user has completed input or has not yet input. The user can use the key unit to determine any input area as a selected area. When the area is a selected area, other areas automatically become unselected areas.

S204: calling the execution unit to determine the state of the selected area according to the attribute of the second key input signal, where the state of the selected area includes: editable state or locked state;

Optionally, the default initial state of the selected area may be a locked state. After the user inputs a second key input signal through the key unit, the execution unit may be called to change the locked state to an editable state according to the attribute of the second key input signal.

Optionally, the state of the selected area may include an editable state and a locked state, wherein in the editable state the user can change the input number in the display area, and in the locked state the user cannot change the input number in the display area, and the editable state and the locked state may be displayed in different colors.

S205: If the state of the selected area is an editable state, the execution unit is called to determine the number of the input number in the selected area according to the attribute of the third key input signal, and the number array and color array stored in the storage unit are called to display the input number and the color corresponding to the editable state in the selected area.

Optionally, when the state of the selected area is an editable state, the user can continue to input a third key input signal through the key unit, and call the execution unit according to the attribute of the third key input signal. In the editable state of the selected area, the number of the input number in the selected area can be determined, and the number array and color array stored in the storage unit can be called to display the input number and the color corresponding to the editable state in the selected area.

Optionally, a digital array can be stored in the storage unit, wherein the storage of the numbers in the digital array can be sequential storage or random storage. For example, array A can be arranged in the order of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or in a random number arrangement of 9, 2, 1, 4, 3, 5, 7, 6, 0, 8. When the input number is 3, the input number determined in the first sequential array is 2, and the input number determined in the second group of random arrays is 1.

Optionally, the color array may also store foreground colors corresponding to the editable state and the locked state. For example, assuming that the foreground colors corresponding to the editable state and the locked area are yellow and black respectively, after determining that the state of the selected area is the editable state, the execution unit may be called to change the foreground color of the selected area from black to yellow.

S206: calling the execution unit to change the state of the selected area from the editable state to the locked state according to the fourth key input signal, and calling the color array stored in the storage unit to display the color corresponding to the locked state on the selected area of the display unit.

Optionally, after completing inputting numbers in the currently selected area, the user can input a fourth key input signal through the key unit, and call the execution unit to change the state of the selected area from an editable state to a locked state according to the fourth key input signal. After the state of the selected area is changed to a locked state, the user can no longer change the input number of the currently selected area.

Optionally, when the state of the selected area changes from an editable state to a locked state, the calling execution unit may call the color array stored in the storage unit to display the color corresponding to the locked state on the selected area of the display unit. By way of example, assuming that the foreground colors corresponding to the editable state and the locked area are yellow and black, respectively, after determining that the state of the selected area is a locked state, the calling execution unit may change the foreground color of the selected area from yellow to black.

S207: Repeat the above steps until the currently received key input signal indicates entering the confirmation area of the display unit, combine the numbers entered in the input area into an input password, call the execution unit to compare the input password with the preset password, and if the comparison result is consistent, start the instrument display system.

Optionally, the user can repeat the above steps S201-S204 during the password input stage until all numbers are entered. During the password input stage, the user can enter all correct numbers at one time, or repeat the above steps to modify any one or more digits after the input is completed until the user enters the confirmation area through the key unit. The input password can be a digital combination of all numbers entered in the input area when the user enters the confirmation area.

Optionally, the user can choose to enter the password input area of the display unit through the key unit. After entering the password, the user can enter the confirmation area of the display unit through the key unit. The method of entering the confirmation area can be the same as the method of switching the input area in the password input area, or a special key unit combination can be used as a key input signal to enter the confirmation area.

Optionally, the calling execution unit can call a preset password in the storage unit and compare the preset password with the input password, and start the instrument display system when the passwords are consistent. The storage unit can store a preset password, and the calling execution unit can compare the input password with the preset password bit by bit after the password is entered to obtain a comparison result for each position.

Exemplarily, the first digit from the left of the input password can be compared with the first digit from the left of the preset password, and then the second digit, the third digit, etc. can be compared in sequence to obtain the comparison results of each position.

If the comparison results of each position are correct, it means that the input password is exactly the same as the preset password. It can be determined that the comparison results are consistent, and a message with the consistent results is communicated to the controller MCU to start the instrument display system and unlock the electric assisted bicycle.

If there is at least one different position in the comparison results of each position, it means that the input password is different from the preset password. The comparison results are determined to be inconsistent. The calling execution unit can call a clear instruction to clear the password, return to the password input interface and output a prompt message to remind the user to re-enter the password.

Next, in conjunction with Figure 5, the instrument display system startup control method of the present application is further explained. As shown in Figure 5, the user can trigger the first key input signal through the plus key or minus key in the key unit shown in Figure 4. First, the selected area is determined from multiple input areas, and the color of the selected area and the color of the unselected area are displayed on the display unit respectively. Then, the second key input signal is triggered by the power key to change the state of the selected area to an editable state, and the color of the selected area is changed to a color corresponding to the editable state to prompt the user to enter a number. In the editable state, the user can trigger the third key input signal by the plus key or minus key to enter a number. After the number input of the currently selected area is completed, the user can trigger the fourth key input signal by the power key to change the selected area from an editable state to a locked state, and change the color of the area to a color corresponding to the locked state.

In the embodiment of the present application, the key unit receives the key signal in sequence, the key signal analysis unit analyzes the signal, and the call execution unit calls the corresponding digital array and color array in the storage unit, and finally displays the call result on the display unit. By setting the input area and the confirmation area for the password input area on the display unit, and the input area includes a selected area and an unselected area, and the selected area includes an editable state and a locked state, the states of each area are independent of each other, and each password can be entered and modified separately, thereby avoiding the problem of clearing all passwords and re-entering the password when one digit is wrong in the password input.

Next, the step of calling the execution unit in the above S203 to determine the selected area among the multiple input areas according to the attribute of the first key input signal, and calling the color array stored in the storage unit to display the corresponding colors on the selected area and the unselected area of the display unit is described. The above S203 step includes:

The execution unit is called to determine the source of the first key input signal. If the source of the first key input signal is the plus key or the minus key, the selected area is determined according to the number of signal triggering times of the first key input signal, and the color array stored in the storage unit is called to display the corresponding colors on the selected area and the unselected area of the display unit.

Optionally, the calling execution unit can determine the source of the signal based on the signal identifier. When the signal identifier indicates that the source of the signal is the plus key or the minus key, the calling execution unit can determine the selected area in the display area based on the number of signal triggers of the first key input signal, call the color array in the storage unit, and display the corresponding colors on the selected area and the unselected area of the display unit.

Exemplarily, the foreground color and background color of the selected area can be yellow and white, respectively, and the foreground color and background color of the unselected area can be blue and black, respectively. After the user confirms that area 1 is the selected area, the calling execution unit can call the foreground color and background color of the selected area and the unselected area in the color array. The foreground color and background color displayed in area 1 are yellow and white, respectively, and the foreground color and background color displayed in the unselected areas such as area 2, area 3 and area 4 are blue and black, respectively.

Next, the step of determining the selected area according to the number of signal triggering of the first key input signal is described. As shown in FIG6 , the step includes:

S601: If the source of the first key input signal is the add key, calculate the sum of the serial number of the currently selected area and the signal triggering times of the first key input signal, and determine the selected area according to the sum of the serial number of the currently selected area and the signal triggering times of the first key input signal.

Optionally, if the source of the first key input signal is the add key, the sum of the serial number of the currently selected area and the number of signal triggering times of the first key input signal is calculated. If the sum does not exceed the maximum serial number of the area, the sum can be used as the serial number of the selected area. For example, as shown in Figure 4, the currently selected area is area 1. If the "plus" key signal appears twice at this time, after judgment, the sum does not exceed the serial number of the largest area (area 4), so the selected area can be moved right from area 1 to area 3.

Optionally, if the sum exceeds the maximum serial number of the area, that is, the number of times the plus key appears exceeds the difference between the serial numbers of the current area and the last area, the area with the largest serial number can be selected as the selected area.

Exemplarily, as shown in FIG. 3 , the password input area is divided into area 1, area 2, area 3, and area 4 in order, where area 3 is the "selected area". If the "plus" key signal appears twice at this time, after judgment, it has exceeded the difference in serial numbers between the current area (the third area) and the last area (the fourth area) (the difference between the third area and the fourth area is 1). Therefore, when the "plus" signal appears for the first time, the "selected area" is moved right from area 3 to area 4. During this process, the background color of the storage unit is called, for example, the background color of area 3 can be replaced with gray, and the background color of area 4 can be replaced with white; and for the second appearance of the "plus" signal, the background color of the color storage unit is no longer called.

S602: If the source of the first key input signal is the minus key, calculate the difference between the serial number of the currently selected area and the number of signal triggering times of the first key input signal, and determine the selected area based on the difference between the serial number of the currently selected area and the number of signal triggering times of the first key input signal.

Optionally, if the source of the first key input signal is the minus key, the difference between the serial number of the currently selected area and the number of signal triggering times of the first key input signal is calculated. If the difference is not less than the minimum serial number of the area, the difference can be used as the serial number of the selected area. For example, as shown in Figure 4, the currently selected area is area 4. If the "plus" key signal appears twice at this time, after judgment, the difference is not less than the serial number of the minimum area (area 1), so the selected area can be moved left from area 4 to area 2.

Optionally, if the difference is smaller than the minimum serial number of the region, that is, the number of occurrences of the minus key exceeds the difference between the serial numbers of the current region and the first region, the region with the minimum serial number can be selected as the selected region.

Exemplarily, as shown in FIG. 3 , the password input area is divided into area 1, area 2, area 3, and area 4 in order, where area 2 is the "selected area". If the "minus" key signal appears twice at this time, after judgment, it has exceeded the difference of 1 between the serial numbers of the current area (the second area) and the first area (the first area). Therefore, when the "minus" signal appears for the first time, the "selected area" is moved left from area 2 to area 1. In this process, the background color stored in the color array is called, for example, the background color of area 2 is replaced with gray, and the background color of area 1 is replaced with white; and for the second appearance of the "minus" signal, the background color of the color array is no longer called.

Next, the steps of calling the color array stored in the storage unit and displaying corresponding colors on the selected area and the unselected area of the display unit are described. As shown in FIG7 , the steps include:

S701: calling a color array, and reading a first color corresponding to a selected area and a second color corresponding to an unselected area from the color array.

Optionally, the plus key and minus key can trigger an execution call instruction for switching the background color in the color array, and trigger a display instruction for changing the background color on the display unit, so that the movement of the "selected area" can be observed on the display unit.

Optionally, after the plus key and minus key trigger the execution call instruction of switching the background color in the color array, the calling execution unit can call the color array to read the first color corresponding to the selected area and the second color corresponding to the unselected area from the color array.

Optionally, the first color and the second color may include a foreground color and a background color. Exemplarily, the foreground color and the background color corresponding to the selected area may be black and white, respectively, and the foreground color and the background color corresponding to the unselected area may be blue and gray, respectively.

S702: Displaying a first color on a selected area of the display unit, and displaying a second color on an unselected area of the display unit.

Optionally, the calling execution unit may display the foreground colors and background colors of the selected area and the unselected area read from the color array on the display unit respectively according to the display instruction of the background color change triggered by the plus key and the minus key.

In an embodiment of the present application, the user triggers a key input signal through the plus key and the minus key. After the key analysis unit analyzes the properties of the key input signal, the calling execution unit can make a corresponding instruction call according to the analysis result, thereby realizing the switching of the selected area. In addition, the embodiment of the present application sets different display colors for the selected area and the unselected area, respectively, which can facilitate the user to identify the current selected area and improve the convenience of user operation.

Next, the step of the calling execution unit determining the number of the input number in the selected area according to the attribute of the third key input signal, calling the number array and the color array stored in the storage unit, and displaying the input number and the color corresponding to the editable state in the selected area is described. The above step S205 includes:

The execution unit is called to determine the source of the third key input signal. If the source of the third key input signal is the plus key or the minus key, the number of the input number in the selected area is determined according to the number of signal triggering of the third key input signal, and the number array and color array stored in the storage unit are called to display the input number and the color corresponding to the editable state in the selected area.

Optionally, after confirming the selected area and changing the state of the selected area from a locked state to an editable state, the user may trigger a third key input signal through the key unit to implement digital input of the selected area.

Optionally, if the source of the third key input signal is the plus key or the minus key, the calling execution unit can determine the number of the input number in the selected area according to the signal triggering times of the third key input signal, trigger the execution calling instruction of switching colors in the color array, trigger the execution calling instruction of switching numbers in the number array, trigger the display instruction on the display unit, and call the number array and color array stored in the storage unit to display the input number and the color corresponding to the editable state in the selected area.

Next, the steps of determining the number of input digits in the selected area according to the number of signal triggering of the third key input signal are described in conjunction with FIG. 8 . Referring to FIG. 8 , the steps include:

S801: If the source of the third key input signal is the add key, then calculate the sum of the number of the current input number in the selected area and the number of signal triggering times of the third key input signal, and determine the number of the input number in the selected area according to the sum of the number of the input number and the number of signal triggering times of the third key input signal.

Optionally, the add key can trigger an execution call instruction of "forward one position/shift right one position" in the digital array. According to the arrangement order of the numbers in the digital array from left to right and the numbering of the numbers in the array from small to large, the corresponding digital numbers of "forward one position/shift right one position" increase incrementally, triggering a digital display instruction on the display unit, so that the changes in the password numbers can be observed on the display unit.

Optionally, if the sum of the number of the currently input number of the selected area and the number of signal triggering times of the third key input signal does not exceed the maximum number in the digital array, the number corresponding to the same number can be used as the input number. For example, the array is arranged in the order of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. Suppose the current input number is 2 and its number in the array is 3. If the "plus" key signal appears twice at this time, after judgment, the sum after addition does not exceed the maximum number of the array. Therefore, the number numbered 5, that is, 4, can be used as the input number.

Optionally, if the sum exceeds the maximum number of numbers in the array, that is, the number of times the plus key appears exceeds the difference between the sequence numbers of the current number and the last number in the array, the number with the maximum number can be used as the input number.

For example, when the array is arranged in random numbers of 9, 2, 1, 4, 3, 5, 7, 6, 0, and 8, assuming that the current input number is 9, which is numbered 1, if the "plus" key has appeared more than 10 times, for example 11 times, then the tenth digit 8 in the array is displayed in the current area.

S802: If the source of the third key input signal is the minus key, calculate the difference between the number of the current input number in the selected area and the number of signal triggering times of the third key input signal, and determine the number of the input number in the selected area based on the difference between the number of the input number and the number of signal triggering times of the third key input signal.

Optionally, the minus key can trigger an execution call instruction of "back one position/shift left one position" in the digital array. According to the arrangement order of the numbers in the digital array from left to right and the numbering of the numbers in the array from small to large, the corresponding digital numbers of "back one position/shift left one position" decrease in sequence, triggering a digital display instruction on the display unit, so that the changes in the password numbers can be observed on the display unit.

Optionally, if the difference between the number of the currently input number in the selected area and the number of signal triggering of the third key input signal is greater than the smallest number in the digital array, the number corresponding to the same number as the difference can be used as the input number. For example, the array is arranged in the order of 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Suppose the current input number is 7 and its number in the array is 8. If the "minus" key signal appears twice at this time, after judgment, the difference is less than the smallest number in the array. Therefore, the number 6, that is, 7, can be used as the input number.

Optionally, if the difference is smaller than the smallest number of numbers in the array, that is, the number of times the minus key appears exceeds the difference between the current number and the first number in the array, the smallest numbered number can be used as the input number.

For example, when the array is arranged in random numbers of 9, 2, 1, 4, 3, 5, 7, 6, 0, and 8, assuming that the current input number is 3, its number is 5. If the "minus" key appears 11 times at this time, the first digit 9 in the array will be displayed in the current area.

Next, the steps of calling the digital array and the color array stored in the storage unit to display the input digital and the color corresponding to the editable state in the selected area are described. As shown in FIG9 , the steps include:

S901: Call the digital array, read the value of the target item from the digital array, and use the value of the target item as the input number, wherein the number of the target item is the number of the input number.

Alternatively, the target item may be an item in a numeric array whose number satisfies the call instruction.

Optionally, the calling execution unit may call a digital array, and read a number corresponding to a digital number indicated by a specified instruction from the digital array, and use the number as an input number.

For example, a call instruction in a digital array indicates that the number 4 needs to be read. Assuming that the numbers in the array are arranged as follows: 4, 1, 2, 5, 8, 7, 9, 6, 3, 0, then the number 5 of 4 can be determined as the input number.

S902: Call the color array and read the color corresponding to the editable state from the color array.

Optionally, when the digital array triggers an instruction to call a number, the calling execution unit may also trigger an instruction to call the color array based on the calling result, and read the color corresponding to the editable state from the color array. For example, the foreground color of the input area in the editable state may be yellow. When no number has been entered in the editable state, a yellow cursor may be displayed first to remind the user that the selected area of the current operation is in an editable state.

S903: Displaying the input number and the color corresponding to the editable state in the selected area of the display unit.

Optionally, the calling execution unit can call the number in the digital array and call the color of the editable state in the color array according to the digital array calling instruction and the color calling instruction, and display the input number and the color corresponding to the editable state in the selected area of the display unit according to the display instruction triggered at the same time.

Exemplarily, the number called in the digital array is 7, and the foreground color of the editable state called in the color array is yellow. Then, it can be observed in the display unit that the selected area changes from the initial yellow cursor to the yellow number 7 in the editable state.

In an embodiment of the present application, by calling corresponding numbers and colors corresponding to editable states in a digital array and a color array, the user can more intuitively identify the position of the selected area of the current operation and the input number on the display unit, thereby improving interactivity with the user.

Next, the key signal analysis unit is further described. The key signal analysis unit may also include a timer and a counter, wherein:

The signal duration is obtained based on the timer analysis. The timer can be set in the key signal analysis unit of the instrument MCU to calculate the signal duration according to the length of time the key is triggered or pressed.

Based on the counter analysis, the number of times the signal occurs is obtained. The counter can be set in the key signal analysis unit of the instrument MCU to count the number of times the signal from the same source occurs.

The signal source is obtained based on the identification of the key input signal. For example, the key signal analysis unit can determine the source of the signal based on the key circuit. For example, the key circuit can be as shown in Figure 10. Key 1 can be the "plus" key, key 2 represents the "power" key, and key 3 represents the "minus" key. Key 1, key 2, and key 3 are respectively connected to the corresponding pins in the instrument MCU to obtain the level changes at the pins of key 1, key 2, and key 3. For example, when the corresponding pin is at a low level, it means that the key has been triggered or pressed. The signal source can be determined based on the location of the pin. For example, the pin level at key 1 is low, indicating that the "plus" key has been triggered or pressed at this time.

In an embodiment of the present application, by setting a timer and a counter in the key analysis unit, it is possible to first determine whether the user's pressing or triggering operation is valid, and then execute the instruction based on the determined valid key input signal. This can avoid inaccurate password input caused by user's mistaken triggering, thereby improving the user experience.
