Optionally, a number array may be stored in the storage unit, where the storage of the numbers in the number array may be sequential storage or out-of-order storage, for example, the array a may be arranged in an order of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, or in an order of 9, 2, 1, 4, 3, 5, 7, 6, 0, 8, and when the number of the input number is 3, the input number determined in the first sequential array is 2, and the input number determined in the second out-of-order array is 1.

In the embodiment of the application, the key unit sequentially receives the key signals, the key signal analysis unit analyzes the signals, the calling execution unit calls the corresponding number array and color array in the storage unit, and finally the calling result is displayed on the display unit. The input area and the confirmation area are arranged for the password input area on the display unit, the input area comprises the selected area and the unselected area, the selected area comprises the editable state and the locked state, the states of the areas are mutually independent, and each password can be independently input and modified, so that the problem that all passwords need to be emptied and input again when one password is input in error is solved.

Next, a description will be given of a step in S203 in which the call execution unit determines a selected region of the plurality of input regions according to the attribute of the first key input signal, calls the color array stored in the storage unit, and displays corresponding colors on the selected region and the unselected region of the display unit, where the step S203 includes:

and calling the execution unit to judge the source of the first key input signal, if the source of the first key input signal is an additional key or a subtractive key, determining a selected area according to the signal triggering times of the first key input signal, 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.

Optionally, the calling execution unit may determine a signal source according to the signal identifier, and when the signal identifier indicates that the signal source is an add key or a subtract key, the calling execution unit may determine a selected region in the display region according to the signal trigger frequency of the first key input signal, call the color array in the storage unit, and display corresponding colors in the selected region and an unselected region of the display unit.

For example, the foreground color and the background color of the selected region may be yellow and white, the foreground color and the background color of the unselected region may be blue and black, respectively, after the user confirms that the region 1 is the selected region, the calling execution unit may call the foreground color and the background color of the selected region and the unselected region in the color array, the foreground color and the background color displayed in the region 1 are yellow and white, respectively, and the foreground color and the background color displayed in the unselected regions, i.e., the regions 2, 3, and 4, are blue and black, respectively.

Then, for the number of signal triggering times according to the first key input signal, the step of determining the selected region is illustrated, and as shown in fig. 6, the step includes:

s601: if the source of the first key input signal is the additional key, calculating the sum of the serial number of the currently selected area and the signal triggering times of the first key input signal, and determining 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 a plus key, the sum of the serial number of the currently selected area and the signal triggering frequency of the first key input signal is calculated, and if the sum does not exceed the maximum serial number of the area, the sum may be used as the serial number of the selected area, for example, as shown in fig. 4, the currently selected area is area 1, and if the "plus" key signal occurs 2 times at this time, the sum is judged to not exceed the serial number of the maximum area (area 4), so that the selected area may be moved from area 1 to area 3.

Optionally, if the sum exceeds the maximum sequence number of the area, that is, the number of times the additional key appears exceeds the difference value between the sequence numbers of the current area and the last area, the area with the maximum sequence number may be used as the selected area.

Illustratively, referring to fig. 3, the password input area is divided into: the method comprises the following steps of 1, 2, 3 and 4, wherein the 3 is a selected area, if an 'adding' key signal appears for 2 times, the difference value of the serial numbers of the current area (the 3 rd area) and the last area (the 4 th area) is exceeded (the difference value of the 3 rd area and the 4 th area is 1) after judgment, therefore, when the 'adding' signal appears for the first time, the selected area is moved from the 3 right side to the 4 th area, in the process, the background color of a storage unit is called, for example, the background color of the 3 can be replaced by gray, and the background color of the 4 can be replaced by white; and for the 2 nd occurrence of the 'adding' signal, the background color execution call of the color storage unit is not performed any more.

Alternatively, if the difference is less than the minimum number of the digits in the array, i.e., the number of occurrences of the minus key exceeds the difference between the current digit and the number of occurrences of the leading digit in the array, the least numbered digit may be used as the input digit.

Illustratively, when the array is arranged by random numbers of 9, 2, 1, 4, 3, 5, 7, 6, 0, 8, assuming that the currently input number is 3, its number is 5, if the "minus" key appears 11 times at this time, the 1 st digit 9 in the array is displayed in the current area.

The key 1, the key 2, and the key 3 are respectively connected to corresponding pins in the instrument MCU to obtain level changes at the pins of the key 1, the key 2, and the key 3, for example, when the corresponding pin is at a low level, it indicates that the key has been triggered or pressed, and the signal source may be determined according to the position of the pin, for example, when the pin at the key 1 is at a low level, it indicates that the "add" key has been triggered or pressed at this time.
