In a further aspect, the display device comprises a nixie tube or an LCD display.
Therefore, the display device can be made into a capacitive touch sensing display by using a common display device, and the design cost is reduced.
In order to achieve the above another object, the present invention provides a password input method for a password input device, including: the controller randomly sends initial password numbers to all the capacitive touch sensitive displays; when the controller acquires a preset sliding induction signal sent by any one capacitive touch induction display, the controller performs increasing or decreasing operation on the password number currently displayed by the currently operated capacitive touch induction display according to the preset sliding induction signal, and the currently operated capacitive touch induction display displays the increased or decreased password number; the controller judges whether a password confirmation signal sent by the currently operated capacitive touch sensitive display is acquired, and if so, the controller determines that the password number currently displayed by the currently operated capacitive touch sensitive display is the selected password number.
According to the scheme, the sliding induction signal is obtained through the capacitive touch induction display, the password number to be input is selected and determined, and the password number input by each key is not a fixed number any more, so that the password character specifically input by the capacitive touch induction display is prevented from being calculated and known, and the password input safety is improved.
In a further aspect, after the controller determines that the currently displayed password number of the currently operated capacitive touch sensitive display is the selected password number, the password input method further includes: the controller judges whether a password hiding signal sent by the currently operated capacitive touch sensitive display is acquired, and if yes, the controller sends preset character information to the currently operated capacitive touch sensitive display.

In a further aspect, after the controller determines that the currently displayed password number of the currently operated capacitive touch sensitive display is the selected password number, the password input method further includes: the controller judges whether the currently operated capacitive touch sensitive display needs to input a next password, and if so, the currently operated capacitive touch sensitive display displays an initial password number corresponding to the next password.
Therefore, the situation that a single capacitance touch induction display needs to input a multi-digit password is possible, the next password can be input after the password number of the previous password is determined, the multi-digit password can be input by using a small number of capacitance touch induction displays, the cost is reduced, and meanwhile, the input of the next password can cover the display of the previous password, and the password input safety can be improved.

Therefore, the pressing signal with the preset duration is used as the amplitude adjusting signal, and the input operation is convenient. The magnitude of the increasing or decreasing amplitude can be determined according to the length of the preset time length, for example, if the pressing time is less than 1 second, the amplitude is 2, that is, the increasing or decreasing amplitude is 2; if the hold-down time is greater than 1 second and less than 2 seconds, the amplitude is 3, i.e., the increasing or decreasing amplitude is 3.
In a further scheme, the determining, by the controller, whether a password confirmation signal sent by a currently operated capacitive touch sensitive display is acquired includes: the controller judges whether the static time of the password number currently displayed by the currently operated capacitive touch sensing display exceeds a second preset time; or the controller judges whether the currently operated capacitive touch sensitive display acquires a click signal in a preset mode.
Therefore, in order to facilitate control to know that the password number is input, a password confirmation signal needs to be sent to the controller to confirm that the password number currently displayed on the capacitive touch sensitive display is the selected password number.

Detailed Description
The password input device is applied to the fields of security protection, industrial technology and the like and is used for guaranteeing the input safety of the password. The password input method of the invention is applied to the password input device of the invention.
As shown in fig. 1, the password input device of the present invention includes a controller 1, a capacitive sensing chip 2, and at least one capacitive touch sensing display 3. Any capacitive touch sensing display 3 comprises a display device 31 and a sensing electrode 32, the sensing electrode 32 is electrically connected with a capacitive sensing chip 2, the capacitive sensing chip 2 is electrically connected with a controller 1, and the display device 3 is electrically connected with the controller 1. The controller 1 obtains the sensing signal of the capacitance sensing chip 2, the controller 1 sends the password character to the display device 31 according to the sensing signal, and the display device 31 switches and displays the password character. Wherein the display device 31 comprises a nixie tube or an LCD display. The sensing electrode 32 is made of conductive glass or conductive metal material.
The number of the sensing electrodes 32 can be set according to the requirement, in this embodiment, the number of the sensing electrodes 32 is four, and the four sensing electrodes 32 are distributed around the display area, and can be used for sensing up-down, left-right sliding operation, clicking or pressing operation, and the like. The capacitive sensing principle is well known to those skilled in the art and will not be described herein. The number of the capacitive touch sensitive displays 3 can be set according to actual needs, and in this implementation, the number of the capacitive touch sensitive displays 3 is 6.
The present invention will be described in more detail below in conjunction with the password input method of the present invention.
Referring to fig. 2, when inputting a password, the password input method of the present invention first performs step S1, and the controller 1 randomly sends an initial password number to all the capacitive touch sensitive displays 3. Before inputting the password, the controller 1 randomly sends the initial password number to all the capacitive touch sensitive displays 3, and the capacitive touch sensitive displays 3 display the corresponding initial password number.
In this embodiment, the initial password number is a password serial number, and the initial password number displayed on each capacitive touch sensitive display 3 represents that the capacitive touch sensitive display 3 needs to input the password number of the corresponding serial number, for example, if the initial password number displayed on a certain capacitive touch sensitive display 3 is "3", the capacitive touch sensitive display 3 needs to input a third digit of the password.
When the controller 1 randomly sends the initial password number to the capacitive touch sensing display 3, the initial password number can be randomly distributed according to the number of digits of the password and the number of the capacitive touch sensing display 3, for example, the number of digits of the password is six, and the number of the capacitive touch sensing display 3 is six, then the controller 1 randomly sends the numbers 1 to 6 to the capacitive touch sensing display 3 respectively for displaying;
it should be noted that, when the number of the capacitive touch sensitive displays 3 is less than the number of digits of the password, a situation that a plurality of password digits need to be input into a single capacitive touch sensitive display 3 may occur, and the controller 1 may randomly select the capacitive touch sensitive display 3 to input the plurality of password digits, that is, the single capacitive touch sensitive display 3 may need to display different initial password digits for multiple times to remind that the currently input password is the number of digits. For example, the number of digits of the password is four, the number of the capacitive touch sensitive displays 3 is two, the controller 1 sends the digits 1 to 4 to the two capacitive touch sensitive displays 3 respectively and randomly for display, and since the number of the capacitive touch sensitive displays 3 is smaller than the number of digits of the password, each capacitive touch sensitive display 3 needs to display two initial password digits, or one capacitive touch sensitive display 3 displays one initial password digit, and the other capacitive touch sensitive display 3 displays three initial password digits.
In addition, when the number of the capacitive touch sensitive displays 3 is 1 and the number of the password is plural, the controller 1 may display the order of inputting the password in a disordered manner, for example, when the number of the password is six, the initial password numbers are sequentially displayed in the order of "6, 4, 2, 5, 3, 1" for the numbers 1 to 6 until the password input is completed.
Certainly, the initial password number may not be the password serial number, and at this time, each capacitive touch sensitive display 3 needs to be fixedly set with the serial number corresponding to the password, so as to avoid the password input error.
After the capacitive touch sensitive display 3 displays the initial password number, step S2 is executed to determine whether the controller 1 obtains a preset sliding sensing signal sent by any capacitive touch sensitive display 3. After the capacitance touch sensitive display 3 displays the initial password number, the user can input the corresponding password number according to the initial password number displayed by the capacitance touch sensitive display 3. The user can slide, click, press operation etc. at electric capacity touch-sensitive display 3, and electric capacity touch-sensitive display 3 acquires user's operating information and sends and handle in electric capacity induction chip 2, and electric capacity induction chip 2 sends the induction signal who obtains after handling to controller 1, and controller 1 carries out induction signal's judgement, confirms what kind of operation the user carries out. The preset slide sensing signal may be operation information for a user to slide up, down, left, right, etc. on the capacitive touch sensing display 3.
When the controller 1 acquires a preset slide sensing signal sent by any one of the capacitive touch sensing displays 3, step S3 is executed, the controller 1 increases or decreases the password number currently displayed on the currently operated capacitive touch sensing display 3 according to the preset slide sensing signal, and the currently operated capacitive touch sensing display 3 displays the increased or decreased password number. After obtaining the preset sliding sensing signal, the controller 1 operates according to the operation instruction corresponding to the preset sliding sensing signal, in this embodiment, the step of increasing or decreasing the password number currently displayed on the currently operated capacitive touch sensing display 3 by the controller 1 according to the preset sliding sensing signal includes: when the controller 1 acquires the upward sliding induction signal, increasing the currently displayed password number, and when the controller 1 acquires the downward sliding induction signal, decreasing the currently displayed password number; or when the controller 1 acquires the induction signal sliding leftwards, the currently displayed password number is increased, and when the controller 1 acquires the induction signal sliding rightwards, the currently displayed password number is decreased. For example, the operation instruction corresponding to the sensing signal of the upward sliding or the sensing signal of the leftward sliding is: adding 1 on the basis of the currently displayed password number; the operation instruction corresponding to the sensing signal of sliding downwards or the sensing signal of sliding rightwards is as follows: the number minus 1 is made on the basis of the password number currently displayed. For example, the currently displayed password number is "3", and if an upward sliding induction signal is acquired, the displayed number is increased by 1 to become "4"; when the sensing signal of the downward slide is acquired, the displayed number minus 1 becomes "2".
It should be noted that, since the capacitive touch sensitive display 3 can only display the numbers 0 to 9, if the currently displayed password number is "0", the subtraction operation is performed, and the displayed password number becomes "9". If the password number displayed at present is "9", the operation of adding 1 is performed, and the displayed password number becomes "0".
The step of increasing or decreasing the password number currently displayed on the currently operated capacitive touch sensitive display 3 by the controller 1 according to the preset slide sensing signal includes: if the controller 1 acquires the amplitude adjusting signal before acquiring the preset sliding sensing signal, the controller 1 increases or decreases the currently displayed password number according to the amplitude corresponding to the amplitude adjusting signal. The magnitude of the increase or decrease of the password number can be adjusted for faster input of the password number. The amplitude adjustment signal is sent to the controller 1 before the slide induction signal is preset.
The amplitude adjustment signal may be an operation signal of pressing or clicking on the capacitive touch sensitive display 3. In this embodiment, the amplitude adjustment signal includes: the capacitive touch sensing display 3 obtains a first preset duration pressing signal. The controller 1 may determine the magnitude of the increasing or decreasing amplitude according to the length of the preset time period, for example, the duration of the press is less than 1 second, the amplitude is 2, that is, the increasing or decreasing amplitude is 2; if the hold-down time is greater than 1 second and less than 2 seconds, the amplitude is 3, i.e., the increasing or decreasing amplitude is 3.
In an optional embodiment, if the amplitude corresponding to the amplitude adjustment signal with the pressing time of less than 1 second is 2, when the controller 1 obtains the operation of "sliding upwards after the pressing time of less than 1 second", the currently displayed password number is increased by 2, for example, the currently actual password number is "3", and after the operation is performed, the displayed password number is "5".
After the step of increasing or decreasing the currently displayed password number is completed, step S4 is executed, and the controller 1 determines whether to acquire the password confirmation signal sent by the currently operated capacitive touch sensitive display 3. After the currently displayed password number is increased or decreased, if the increased or decreased password number is the password number required by the user, a confirmation operation may be performed so that the controller 1 can know the password number required by the user of the currently displayed password number.
The step of judging whether to acquire the password confirmation signal sent by the currently operated capacitive touch sensitive display 3 by the controller 1 includes: the controller 1 determines whether the static time length of the password number currently displayed by the currently operated capacitive touch sensitive display 3 exceeds a second preset time length. When the password number currently displayed by the capacitive touch sensitive display 3 exceeds a second preset duration, the controller 1 regards that the password confirmation signal is obtained. The static time duration refers to the time length that the currently displayed password number does not change any more, and the second preset time duration can be set by a program developer. For example, when the password number currently displayed on the capacitive touch sensitive display 3 exceeds 2 seconds, the controller 1 regards that the password confirmation signal is acquired.
The step of judging whether to acquire the password confirmation signal sent by the currently operated capacitive touch sensitive display 3 by the controller 1 further includes: the controller 1 judges whether the currently operated capacitive touch sensitive display 3 acquires a click signal in a preset manner. When the currently displayed password number is confirmed to be the required password number, a confirmation signal can be sent through the capacitive touch sensitive display 3. In this embodiment, the click signal in the preset manner is: and after the capacitance touch sensitive display 3 displays the increased or decreased password number, clicking once or continuously clicking twice on the capacitance touch sensitive display 3. When the controller 1 acquires the click signal in the preset mode, it is determined that the password confirmation signal is acquired.
When the controller 1 determines to acquire the password confirmation signal sent by the currently operated capacitive touch sensitive display 3, the process returns to step S2, and it is continuously determined whether the preset sliding sensing signal is acquired. In addition, after the step S2 is executed, if the controller 1 determines that the preset slide sensing signal sent by any capacitive touch sensing display 3 is not acquired, the step S4 is executed, and the controller 1 determines whether the password confirmation signal sent by the currently operated capacitive touch sensing display 3 is acquired.
After the controller 1 determines that the password confirmation signal sent by the currently operated capacitive touch sensitive display 3 is acquired, step S5 is executed, and the controller 1 determines that the password number currently displayed by the currently operated capacitive touch sensitive display 3 is the selected password number. After the controller 1 obtains the password confirmation signal, it is determined that the password number currently displayed on the capacitive touch sensitive display 3 currently operated is the selected password number. When the controller 1 determines that the password number currently displayed by the currently operated capacitive touch sensitive display 3 is the selected password number, the password corresponding to the password number is obtained. Of course, the selected password number is not necessarily the final password number, and the modification can be continued by sending a preset sliding induction signal after the selected password number is determined.
After the controller 1 determines that the password number currently displayed by the currently operated capacitive touch sensitive display 3 is the selected password number, the controller 1 determines whether to acquire a password hiding signal sent by the currently operated capacitive touch sensitive display 3, and if so, the controller 1 sends preset character information to the currently operated capacitive touch sensitive display 3. The hidden password signal may be an operation signal such as clicking, sliding or pressing on the capacitive touch sensitive display 3. The character information may be characters other than numbers, such as H, x, etc., that can be displayed by the display device 31. For example, after the controller 1 determines that the currently displayed password number of the currently operated capacitive touch sensitive display 3 is the selected password number, if a password hiding signal under three consecutive clicks is acquired, the controller 1 sends preset character information "H" to the capacitive touch sensitive display 3, and the currently displayed password number is replaced by "H" for display.
In addition, after the controller 1 determines that the currently displayed password number of the currently operated capacitive touch sensitive display 3 is the selected password number, the controller 1 determines whether the currently operated capacitive touch sensitive display 3 needs to input a next password, and if so, the currently operated capacitive touch sensitive display 3 displays an initial password number corresponding to the next password. In order to facilitate a user to input a multi-digit password number by using the same capacitive touch sensitive display 3, after the last password is determined, the controller 1 sends an initial password number corresponding to the next password to the capacitive touch sensitive display 3, so that the user can input the next password.
After all the password numbers are input, the controller 1 may perform an authentication operation on all the password numbers, thereby determining whether the input password is correct. When determining whether the password number has been completely input, a confirmation signal may be transmitted through a key electrically connected to the controller 1, or when the time length for stopping the operation exceeds a certain time length, the confirmation signal is considered to be acquired, so that the controller 1 verifies the password.
Therefore, the password input device of the invention replaces the existing input keys with the capacitive touch sensitive display, the capacitive touch sensitive display can switch the password characters displayed by the display device according to the sensing signal, and the mode of inputting the fixed character information by the existing input keys is changed, so that the specific input password characters by the capacitive touch sensitive display cannot be obtained even if the touch position of the capacitive touch sensitive display is obtained, thereby improving the password input safety. In addition, the password input method obtains the sliding induction signal through the capacitive touch induction display, and selects and determines the password number to be input, so that the password number input by each key is not a fixed number any more, the password character specifically input by the capacitive touch induction display is prevented from being calculated and known, and the password input safety is improved.
It should be noted that the above is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept also fall within the protection scope of the present invention.
