When a visitor comes to visit, press the button on the outdoor station to call the user, the user can see the visitor on the display screen and can talk to the visitor, and the user can remotely open the door lock by touching the door open button. The user himself can open the door lock by inputting the password on the door station.

At present, the door opening password of the outdoor station is usually set by the property management company and changed regularly. The property management company is responsible for sending the new password to the user's mailbox or mobile phone to inform the user.

There are some defects in the setting method of the above-mentioned door-opening password. 1. Many users share a password, which will easily cause the leakage of the password and bring hidden dangers to the personal and property safety of the user; 2. The password set by the property company is very strange to the user. It is easy to forget the password, causing the user to be unable to open the unit door, and the user also has to remember the different passwords that are changed regularly, which adds difficulties to the user; Just can't open unit door, bring trouble and inconvenience to user.

In view of the above problems, people have proposed a password setting method, the user can modify the original password on the door machine, so that each user can set his own password for opening the door.

The defect of this method of setting the door-opening password is: modifying the password in a public place will easily cause the leakage of the password, and if someone maliciously sets the password of other users on the door station, the user himself will not be able to open the door, which will cause inconvenience to the user. .

Detailed ways

Figure 1 is the architectural diagram of the building access control system. As shown in the figure, each indoor station and outdoor station in the building are connected to each other through an Ethernet switch, and a local area network based on the Linux operating system can be used. The indoor station and outdoor station have human-computer interaction interface, which can be made by MiniGUI. The indoor station and outdoor station can transmit audio and video data through UDP protocol, and can also transmit data through 485 communication protocol. The indoor station includes an indoor station processing unit 100, and the outdoor station includes a outdoor station processing unit 200. The indoor station processing unit 100 and the outdoor station processing unit 200 may use an ARM10 processor.

FIG. 2 is a schematic diagram of the composition of the password setting device of the building access control system. As shown in the figure, the indoor unit processing unit 100 includes:

The password receiving subunit 101 is configured to receive the password input by the user; both the authentication password and the new password input by the user are received by the password receiving subunit 101 .

The authentication subunit 102 is configured to authenticate the identity of the user who inputs the password. The authentication subunit 102 stores the correct password, and authenticates the user identity by judging whether the authentication password input by the user received by the password receiving subunit 101 matches the stored correct password. If the authentication password input by the user received by the authentication subunit 102 matches the correct password stored in the authentication subunit 102, the user identity is authenticated; otherwise, the user identity is judged to be illegal.

The password limiting subunit 103 is configured to determine whether the new password received by the password receiving subunit 101 is valid. For example, the password restriction subunit 103 stores a restricted password list, which includes the most commonly used simple digital passwords, such as 123456, 111111, 00000, 888888 or other types of restricted passwords, by comparing the received new password with the stored restricted password to determine whether the received new password is valid. If the new password is consistent with any password in the list, it is judged that the new password is invalid, otherwise it is valid. The list may also include other conditions, for example, when it is judged that the number of digits of the password entered by the user does not meet the requirement of digits (for example, the input password should be 6 digits), the new password is also considered invalid.

The encryption subunit 104 is configured to encrypt the new password received by the password receiving subunit 101 .

The password transmission subunit 105 is configured to send the encrypted password to the outdoor station processing unit 200 through the local area network TCP protocol.

The outdoor machine processing unit 200 includes:

A password receiving subunit 201, configured to receive the encrypted password sent by the indoor unit processing unit 100;

The decryption subunit 202 is configured to decrypt the encrypted password received by the password receiving subunit 201 .

The door-opening password generating subunit 203 combines the decrypted password with the room identification information corresponding to the IP address sending the password to generate the password required for opening the door. The door-opening password generating subunit 203 pre-stores the room identification information and IP address corresponding to each indoor unit. The room identification information and the IP address are stored correspondingly, and the room identification information corresponding to the indoor unit that sends the password can be known according to the IP address that sends the password. Wherein the composition format of the room identification information can be as shown in Figure 3, including the community number of 2 bytes, the building number of 2 bytes, the unit number of 1 byte and the room number of 2 bytes, wherein, the room identification can be Information or part of the information it contains, such as room number as room identification information. It can also contain floor numbers etc. The format of the password to open the door is shown in Figure 4. It consists of a 2-byte room number and 6-byte password information, where 1 byte in the password information represents a character input by the user. For example, if the new password entered by the user whose room number is 402 is 256489, the generated password required to open the door is 402256489, which means that the user can only open the door by inputting the password 402256489 on the outdoor station. Adding the room number to the door opening password can increase the security level of the password, which is not easy to be cracked. It should be noted that the room identification information may also be other information preset by the user, such as specific digital information, which may be realized by providing a corresponding input interface on the indoor unit. When it is specific digital information, if the password is modified by other people, because he does not know the specific digital information preset by the user, he cannot open the access control. Of course, in order to prevent the user from forgetting the specific digital information set by him, a procedure for clearing or canceling the information should also be set up just in case.

The password storage subunit 204 is used for storing the password required for opening the door. The password storage unit can adopt 128M RAM or 256M FLASH.

Fig. 5 is the flowchart of password setting method, as shown in the figure, comprises the following steps:

Step 501, the password receiving subunit 101 of the indoor unit processing unit 100 receives the authentication password input by the user on the interactive interface of the outdoor station, and the authentication subunit 102 performs authentication. After passing the authentication, the user can log in and enter the set password interface.

Step 502, the password receiving subunit 101 of the indoor unit processing unit 100 receives the new password input by the user on the password setting interface.

Step 503, the password restriction subunit 103 of the indoor unit processing unit 100 judges whether the new password input by the user is a valid password, and when it is judged that the input password is an invalid password, prompts the user through the interactive interface that the password input is invalid, and prompts to re-enter other passwords ; When the judgment is valid, proceed to the next step.

Step 504 , the encryption subunit 104 of the indoor unit processing unit 100 encrypts the accepted new password using the MD5 encryption method.

Step 505 , the password transmission subunit 105 of the indoor station processing unit 100 sends the encrypted new password to the outdoor station processing unit 200 . As shown in FIG. 1 , it can be sent to the remote outdoor station processing unit 200 through the network.

Step 506 , the password receiving subunit 201 of the outdoor station processing unit 200 receives the encrypted password sent by the indoor station processing unit 100 .

Step 507 , the decryption subunit 202 of the outdoor station processing unit 200 decrypts the received encrypted password using the MD5 decryption method. It is not difficult to understand that when other encryption methods are used in step 504, corresponding decryption methods need to be used in this step.

Step 508 , the door opening password generating subunit 203 of the outdoor station processing unit 200 combines the decrypted password with the room identification information to generate a password required for opening the door.

Step 509 , the password storage subunit 204 of the outdoor station processing unit 200 stores the generated password required for opening the door.

The encryption subunit 104 may also use other encryption methods to encrypt the password, such as an encryption method in which the password is reversed. Correspondingly, the decryption subunit 202 inverts the received password for decryption. Of course, the room identification information may also include information such as a unit number. In addition, when generating the door-opening password, if the security level of the password is not high, it is also possible to use only the stored password, that is, the password set by the user, as the door-opening password.
