Therefore, the password input control method of the password lock device of the present invention includes the following steps: (A) enabling the password lock device to control a plurality of touch display areas and displaying at least one password symbol respectively, and locking the password lock When one of the touch display areas enabled at the time is operated, the device controls the touch display areas to be re-enabled and respectively displays at least one password symbol again, and controls at least one of the touch display areas in front and back The at least one cipher symbol that is displayed twice is different; (B) enables the cipher lock device to obtain a display that is currently displayed on the touch display area each time one of the enabled touch display areas is operated A password corresponding to at least one password symbol; and (C) causing the password lock device to form multiple input passwords into an input password group and change to an unlock when the correct input password group is judged according to a correct password group status.

The effect of the present invention is to drive the code lock device to control these touch display areas to be enabled multiple times, and each time it is enabled, a different password symbol design is displayed, which can greatly improve the password guessed by others based on the touch operation traces. Difficulty, and can effectively improve the safety of the combination lock device.

The present invention will be further described in terms of the following embodiments, but it should be understood that these embodiments are for illustrative purposes only, and should not be construed as limitations on the implementation of the present invention, and similar elements It is represented by the same number.

Referring to FIGS. 1, 2, and 3, the first embodiment of the password input control method of the password lock device 200 of the present invention is suitable for being implemented in a password lock device 200 through electronic circuits and/or software programs, and can be used to control the password lock Password input of device 200. The combination lock device 200 has a touch display module 201. The touch display module 201 is a touch-sensitive liquid crystal display, and has a plurality of touch display areas 202 arranged at intervals and available for touch operation.

The first embodiment of the password input control method of the password lock device of the present invention includes the following steps:

Step 901: Switch to display the password symbol. When the password lock device 200 activates a password input mode, the touch display areas 202 of the touch display module 201 are controlled to be enabled for touch operation, and the enabled touch displays are enabled Each area 202 displays a password symbol 203, that is, the touch display areas 202 of the password lock device 200 display a plurality of different password symbols 203 for selection.

In the first embodiment, the code lock device 200 is driven to control the distribution of the code symbols 203 displayed in the touch display area 202 in a random distribution display mode or a pseudo random distribution display mode, that is to say, Each time the combination lock device 200 drives the touch display areas 202 to display the arrangement and distribution of the combination symbols 203 in different ways.

In the first embodiment, the cryptographic symbols 203 are the numbers "0" to "9", but in implementation, in other implementation forms of the present invention, the cryptographic symbols 203 may also be the English letter "A "~"Z", or graphic symbols "#", "%"..."∑", etc., and not limited to the above types.

Then, when one of the touch display areas 202 that is enabled at the time is touch-operated, the code lock device 200 is controlled to re-enable the touch display areas 202 once, and a password symbol 203 is redisplayed separately And will control each touch display area 202 to display different password symbols 203 twice before and after. Taking a numeric type of password symbol 203 as an example, when a touch display area 202 is currently enabled and the password symbol 203 is displayed as a number 0, the touch display area 202 will be enabled and displayed this time The cryptographic symbols 203 other than the number 0, such as the number 7, such as the display changes shown in FIGS. 3 and 4.

During the implementation, the number of bits of a correct cipher set that the cipher lock device 200 is scheduled to input is determined, and the number of times the cipher lock device 200 is to be driven to display the cipher symbols 203 again is determined. For example, when a correct password set is an 8-digit password, the password lock device 200 needs to be driven to switch and display the content of the password symbol 203 eight times for eight operations to input eight passwords. However, during implementation, in another embodiment of the present invention, the set number of switching times is not limited, so that the combination lock device 200 can be operated every time one of the enabled touch display areas 202 is operated to input a code , Re-enable and display once.

In this embodiment, in step 901, when the code lock device 200 controls the touch display areas 202 to redisplay the code symbols 203, each touch display area 202 is controlled to display Different password symbols 203, but during implementation, in another embodiment of the present invention, only a few of them or at least one of the touch display areas 202 can be controlled to display different password symbols twice before and after 203, and in this case, part of the touch display area 202 can display the same password symbol.

Step 902: Extract the password and establish the input password group. Each time the code lock device 200 is enabled, one of the touch display areas 202 is touch-operated, obtain a code corresponding to the code symbol 203 currently displayed in the touch display area 202, and then pass the specified number of times before and after The obtained passwords are arranged in the order of acquisition to form an input password group. However, during implementation, the combination of the passwords obtained multiple times before and after to form the input password set is not limited to this.

Step 903: Determine whether the input password group is correct. The combination lock device 200 judges whether the input code set is correct according to one or more correct code sets built in advance, and causes the combination lock device 200 to change to an unlocked state when determining that the input code set is correct.

Referring to FIGS. 2, 3 and 4, when the password input control method of the password lock device of the present invention is implemented, when the password lock device 200 is activated in the password input mode, these methods are controlled in a random distribution display mode or a pseudo-random distribution display mode. The touch display area 202 displays the password symbols 203, as shown in FIG. 3, and after one of the touch display areas 202 is operated, the display currently displayed on the touch display area 202 operated by the touch is immediately extracted A password corresponding to the module number. Then, the enabling of the touch display area 202 is controlled again, and the password symbols 203 are redisplayed in a new distribution mode for selection operation, as shown in FIG. 4. This display control step is repeated multiple times until a predetermined number of passwords have been extracted and constitute the input password group.

Then, the combination lock device 200 determines whether the input code set is correct according to the built-in correct code set, and changes to the unlocked state when the input code set is determined to be correct.

Referring to FIGS. 2, 5, and 6, the main difference between the second embodiment of the password input control method of the combination lock device of the present invention and the first embodiment lies in: the design of the password display control method in step 901, and the step 902 in Design of password extraction method. For convenience of description, only the differences between the second embodiment and the first embodiment will be described below.

In the second embodiment, this step 901 is to control each enabled touch display area 202 to display two password symbols 203 simultaneously, for example, to enable the enabled touch display areas 202 to display The password symbols 203 representing numbers 0 to 9, respectively, and the password symbols 203 displayed on the touch display area 202 are, for example, "0/1", "2/6", "5/8", "" "3/7" and "9/4". In this embodiment, the distribution of the password symbols 203 displayed on the touch display area 202 is controlled in a random distribution display mode or a pseudo-random distribution display mode, that is, the step 901 controls the touch The arrangement and distribution of the password symbols 203 displayed on the control display area 202 each time are different.

Next, when one of the touch display areas 202 is touch-operated, the combination lock device 200 is re-driven to enable the touch display areas 202 again, and each touch display area 202 is enabled twice before and after The two displayed password symbols 203 are completely different, or at least one of them is different, so that the touch display areas 202 of the entire password lock device 200 will show different distribution patterns of the password symbols 203 each time, which is not easy It was guessed by others to show regularity.

The step 902 is to enable the password lock device 200 to obtain two password symbols 203 that are currently displayed with the touch display area 202 each time one of the touch-enabled display areas 202 that is enabled is operated. Corresponding passwords, and arrange one of the passwords obtained this time and one password obtained from other times in the order of obtaining, and arrange the multiple passwords obtained multiple times to form an input password group, which will constitute multiple input passwords group.

Taking FIGS. 5 and 6 as examples, when the touch display area 202 showing “0/1” in FIG. 5 is operated, the password lock device 200 is used to extract the password “0” and the password “1”. Next, the code lock device 200 is redisplayed with different distribution states of the code symbols 203, as shown in FIG. 6, at this time, when the touch display area 202 showing "6/3" shown in FIG. 6 is operated, the code is enabled The lock device 200 extracts the password "6" and the password "3". Then, each password obtained according to FIG. 5 and each password obtained according to FIG. 6 are arranged in the order of acquisition, and four kinds of arrangement combinations are formed, “06”, “03”, “16”, and “13”. By analogy with this method, the passwords acquired a predetermined number of times are arranged and combined in the order of acquisition to generate multiple input password sets.

The step 903 is to enable the combination lock device 200 to analyze and compare the input code groups according to the built-in one or more correct code groups, and change to the unlocked state when it is judged that one of the input code groups is correct.

In summary, by driving the combination lock device 200, the touch display module 201 can be controlled to be enabled multiple times, and the touch display areas 202 can display different arrangements of the arrangement of the code symbols 203 each time, and Whenever the enabled touch display area 202 is operated, the touch display area 202 is driven again to redisplay the design of the password symbol 203, so that each time the user wants to enter the password, the The operation sequence operates different touch display areas 202, which greatly increases the difficulty of guessing passwords based on the operation traces of the touch display areas 202 by others, and can further drive the enabled touch display areas 202 at the same time The design of two password symbols 203 is shown, and the use security of the entire password lock device 200 is further improved. Therefore, the purpose of cost invention can indeed be achieved.
