Each time the central control module 5 activates the password input mode, the display control unit 51 controls the touch display area 41 of the touch display module 4 to be enabled, and drives each of the enabled ones. The touch display area 41 simultaneously displays two password symbols 410, for example, the numbers 0 and 1 are displayed at the same time, and the touch symbols 41 are displayed by the touch display area 41 for inputting a required password, for example, a total of Ten cipher symbols 410, such as numbers 0-9, are displayed. In this embodiment, the display control unit 51 controls the display of the touch display areas 41 in a random distribution display manner or a pseudo-random distribution display manner. The distribution of the password symbol 410, that is, the password symbol 410 displayed by the touch display area 41 of the touch display module 4 each time the central control module 5 activates the password input mode. The arrangement is different.

The password extraction unit 52 extracts two passwords corresponding to the two password symbols 410 currently displayed by the touch display area 41 when the one touch display area 41 is enabled, and the password is During the startup of the input mode, one of the two passwords obtained by the touch display area 41 and the two passwords obtained by the other touch display area 41 are The touch display area 41 is arranged and combined in order of operation to form an input password group, so that a plurality of input password groups are generated.

The password judging unit 53 analyzes the input cipher group according to the correct cipher group set, and judges that the correct password has been input when one of the input cipher groups matches one of the correct cipher sets, and the corresponding password is controlled. The lock module 3 changes to the unlocked state.

When the second embodiment is used, it is exemplified as follows. In order to facilitate the difference between the touch display areas 41 in the following description, the touch display areas 41 to be enabled are referred to as the first area and the second, respectively. The area, the third area, the fourth area, and the fifth area, and the first to fifth areas of FIG. 5 show the password symbols 410 in the order of "0/1", "2/6", and "5". /8", "3/7" and "9/4". When the user enters an input password group of "101538", the first zone, the first zone, the first zone, the third zone, the fourth zone, and the third zone must be operated in sequence. At this time, the central control module 5 combines a password of each area to be operated according to the sequence of operations, and obtains a plurality of input password groups, such as "001533", "011875", and "101538", and the like. When one of the input password groups matches the correct password group "101538", the password is judged to be correct, and the lock module 3 is further controlled.

In the second embodiment, the two password symbols 410 displayed in each touch display area 41 are designed to be completely different from the two password symbols 410 displayed by the other touch display areas 41. However, in implementation, in another embodiment of the present invention, the display control unit 51 can be designed to cause one or more of the two cryptographic symbols 410 displayed in the touch display area 41 to be enabled. One of them is the same as one of the password symbols 410 displayed by the other touch display area 41.

Referring to FIG. 6 , in addition, in the second embodiment, when the password input mode is activated, the central control module 5 drives the touch display module 4 to be enabled once, and is operable to input the inputs. The passwords of the cipher suites, that is, during the activation of the cipher input mode, the touch display areas 41 that are enabled are available for selection multiple times to input the password of the required number of bits. In another implementation manner of the present invention, during the activation of the password input mode, the display control unit 51 controls the touch display module 4 to be enabled multiple times, each time driving the touch. The touch display area 41 of the display module 4 is enabled to display two password symbols 410, and the touch display area 41 can be controlled again when one of the touch display areas 41 is operated. Once again, the two password symbols 410 are redisplayed separately. For example, to input eight passwords, the touch display module 4 is driven to enable eight times in total.

In summary, the touch display module 4 and the central control module 5 of the combination lock device 200 can drive the touch display module 4 every time the password input mode is activated. Each time the touch display area 41 displays a different password symbol 410, the user can operate different touch display areas 41 in different operation sequences each time the user inputs the password, and further drives the enabled ones. The touch display area 41 simultaneously displays the design of the two password symbols 410, and when the one touch display area 41 is enabled, the touch display module 4 is again driven to display different password symbols. The design of the display content of the 410 is greatly improved, and the difficulty of guessing the password by the operation trace of the touch display module 4 is greatly improved, and the security of the use of the entire password lock device 200 can be further improved. Therefore, it is indeed possible to achieve the purpose of the present invention.
