Description

Key input structure and method of electromagnetic device

The present invention is to reduce the number of the input device while blocking the theft of the password by the combination of several input keys in the electronic key device for recognizing the key input from the keypad to open and close the door.

As shown in FIG. 1, the electronic key device includes an input unit 10 including ten input keys from 0 to 9 and a control unit that recognizes key input of the input unit 10 and performs various functions such as opening and closing operation and display. 30, an external display unit 20 which displays the key input state externally to assist in password input, an opening / closing movable unit 40 for opening and closing the locking device by the control of the control unit 20, and the key input state. And an internal display unit 50 for displaying the open / closed state and the like, and a power supply unit 70 for supplying power, so that the control unit 30 transmits the open / close information to the remote site through the communication unit 60 as necessary. can do.

In the basic operation of the electronic key device, when the password is sequentially input by the input unit 10, the controller 30 releases the locking device by driving the opening / closing operation unit 40 only when they match each other compared with the previously stored password. The doors, car doors and cabinets can be opened.

Electronic key device has the advantage that there is no inconvenience to carry the key and can prevent illegal opening by other people unless the password is leaked, but the key input method of the existing electronic key device has the following problems.

First of all, the key pad of the existing electronic key device is composed of 10 numeric keys ranging from 0 to 9, so that the number of key configurations is large.

In general, four-digit number is used to enter the password. Since the password is not changed frequently, only the input key is pressed every time. Therefore, the input key and the input key that are frequently pressed are displayed. Is easy to find.

Therefore, if four input keys are combined, up to 24 cases can be made, and if pressed sequentially, the electronic key is easily opened within 24 times.

The present invention is to reduce the number of input keys, but by combining the input keys to enter a password so that others can not easily find the password.

That is, the present invention reduces the number of input keys, but by combining the password according to the number and type of pressing the input keys, so that even if the number of input keys is small, it is impossible to input password by others.

In the present invention, a combination of a password is inputted by pressing an input confirmation key indicating the number 0 input and an input confirmation and an input key increasing by 1, 2 or 3 each time, and pressing the input confirmation key every time a number is entered and the input key. The present invention is performed by recognizing a password by a combination as a decimal password, comparing the stored password with a stored password, and then performing a lock opening / closing operation.

The input unit 10 of the present invention is configured using a few input keys as shown in Figure 2, but the total number of keys is suitable not to exceed five, one of the keys is the number 0 input and number input It consists of input confirmation key to confirm.

In other words, when composed of two keys as shown in (A) of Fig. 2 consists of an input confirmation key ⓞ and an input key ① that increases by one each time it is pressed once, and composed of three keys as shown in (B) of FIG. Confirmation key ⓞ One, input key that increases by 1 each time press ① ① Input key ② that increases by 2 each time, one press once and input key ② when composed of four keys as shown in (C) of FIG. One, the input key to increase by 1 each time press ① ① One, the input key to increase by 2 each time to press ② One, the input key to increase by 3 each time to press one ③ One configuration and as shown in Fig. 2 (D) In case of 5 keys, input confirmation key ⓞ one, input key increases by 1 every press ① One, input key increases by 2 every press ② One, input key increases by 3 every press ③ One , Consists of input key ④ that increases by 4 each time.

The present invention may have any key configuration, but it is most suitable to have three or four key configurations for ease of use and installation.

In the present invention, a method consisting of four keys and a password 5096 will be described in detail.

First, 5, the first digit of the password, press input key ① five times and then press the input confirmation key ⓞ, or press input key ② twice and press the input key ① and then press the input confirmation key ⓞ or press the input key ③. And press the input key ② once and then input the input confirmation key ⓞ.

In other words, regardless of the order and number of pressing the input device ①, input key ②, and input key ③, press the input key to satisfy the number 5, press the input key, and then press the input changeover key ⓞ to complete the input of the password 5.

Second, 0, the second number of password, press the input confirmation key ⓞ.

In this case, the input confirmation key ⓞ means the input of the number ⓞ when pressed alone, and the completion of the number input when pressed in combination with the input key.

Third, for the third number 9, press input key ③ three times and press input confirmation key ⓞ, or press input key ② three times and press input key ③ once and then press input confirmation key ⓞ or other input keys ①, ② Press, ③ to combine the number 9. And then press the Input Confirmation key ⓞ to input it.

Fourth, the fourth number 6, the input key ② is pressed three times and the input confirmation key ⓞ is pressed, or the input device ② is pressed twice and the input confirmation key ⓞ is pressed or other input keys ①, ②, ③ are combined. After that, input the confirmation key ⓞ.

In contrast, in the case of using three input keys as shown in FIG. 2 (B), after combining the password numbers from 0 to 9 using the input confirmation key ⓞ, the input key ① and the input value ②, press the input confirmation key ⓞ to input. Just do it.

When the password is input in the manner as described above, the control unit 30 converts the number input every time the input confirmation key ⓞ is pressed into a decimal number, and then compares and compares it with a predetermined password. To release the lock.

Thus, the present invention can be used to enter the password using three or four input keys can reduce the keypad installation area, unlike the existing, easy to install and also enter the password by combining the input key password even if the number of input keys is small It's almost impossible to find a password, so there's no risk of your password being compromised.

The operation of the control unit 30 during key input by the key input method described above will be described with reference to FIG. 3.

In order to save battery power, first, it waits in the sleep mode to cut off unnecessary power supply and detects whether there is a key input. If there is any key input, the key flag and input key value are designated as initial values. Set the type of input device according to and corresponding variable.

Then, check the type of input key, set the variable for it, and check whether the input confirmation key is input.

When the input confirmation key is pressed, the LOOP counter is increased so that the next digit password can be input and the combined input key value is saved (KSUM (LOOP)).

Check the maximum digit of the combined input key value and repeat the routine if it is not the maximum digit. If the maximum digit is compared with the stored password, if the password does not match, continue to detect the key input and release the lock when the password is entered.

On the other hand, if the sum value exceeds 9 by adding the key value of input key, it is wrong input. Therefore, after clearing the sum value, add the input key value from the beginning again. To increase the loop counter.

On the other hand, in order to change the password specified in the present invention by pressing a predetermined password, such as the flow chart of Figure 4 to perform a password designation routine when it matches the stored password and the encryption designation routine as shown in the flowchart shown in FIG. Temporarily save the newly assigned password and enter the password again to save the password if they match.

That is, when changing the previously stored 5096 password to 3204, press the password 5096 as shown in the flowchart of FIG. 4 to perform the password assignment routine as shown in FIG. 5, and temporarily press 3204, the password to be changed in FIG. After confirming the entry, you will save the new password as 3204.

This is to prevent a malfunction due to the password change and to make sure that the password change is recognized by the user.

The present invention can minimize the number of the input key, but can not combine the password without knowing the exact password can maintain a near-perfect security and the input key is small, the design and construction of the input unit is simple and beautifully designed appearance You can do it.
