Description

Technical Field

[0001] The present invention relates to the technical field of elevator control, and more particularly, to a method for using floor buttons as password-controlled elevator rides. Background Art

[0002] Currently, elevators are widely used in scenarios such as residential buildings and commercial buildings. However, there are still deficiencies in the access control for specific floors (such as private offices, storage rooms, etc.). Existing technologies usually use external password control boxes or IC card controllers for floor control. For example, access to restricted floors can only be achieved by entering a password or swiping a card for verification. However, such solutions have significant drawbacks;

[0003] Installing a password control box or an IC controller requires additional hardware investment, increasing the installation and maintenance costs; IC cards are easily lost or stolen, and are inconvenient to carry, making it difficult to meet the needs of dynamic permission management; when the floor permissions need to be changed, it is necessary to reconfigure the hardware or reissue IC cards, and the operation process is cumbersome and inefficient. Therefore, we have made improvements and proposed a method for using floor buttons as password-controlled elevator rides. Summary of the Invention

[0004] The present invention provides a method for using floor buttons as password-controlled elevator rides, including the steps of:

[0005] An operation box provided in the elevator car, the operation box having an enclosed small door integrating a three-position switch, an instruction board, and a display board; the instruction board is connected to the car top board, and the car top board is connected to a main control board;

[0006] The three-position switch has a set position, an on position, and an off position. When the three-position switch is switched to the set position, by registering the floor button, the instruction board of the operation box records its value, and the input value is used as the floor registration password. At the same time, the input button will be lit and scrolled on the display board in the order of input;

[0007] After the elevator installation and commissioning are completed, turn the three-position switch to the set position. At this time, input a high-level signal to the set mode IO port of the car top board, and the car top board interacts with the main control board to enter the password setting mode. At this time, the display board shows "---". Continuously input 3 floor buttons as the password, and the input floor values are displayed on the display board in the order of input. After the setting is completed, the input button continuously flashes, indicating that the setting is successful;

[0008] If the three-position switch is turned to the on position, the floor login is password-controlled. After the passenger successfully inputs the corresponding password, the controlled floor is registered;

[0009] If floor control is not required, turn the three-position switch to the off position to open the floor control.

[0010] As a preferred technical solution of the present application, the car top board communicates with the main control board and the instruction board through CAN communication, and the instruction board communicates with the display board through MOD communication.

[0011] As a preferred technical solution of the present application, when resetting the password, the three-position switch needs to be turned to the set position, and the corresponding floors of the originally set password buttons will be lit. Double-click to cancel the numerical setting of a certain floor, and then re-enter the password value to be set. After the reset is completed, the three-floor buttons will continue to flash.

[0012] As a preferred technical solution of the present application, during the password setting process:

[0013] The three-position switch triggers the car top board to enter the set position through the IO point signal. The car top board and the main control board interact through the CAN communication protocol to complete password storage and permission configuration;

[0014] The display board initially displays "---", and is replaced by the corresponding numerical values one by one according to the input order of the floor buttons to form a dynamic visual interaction interface.

[0015] As a preferred technical solution of the present application, the enclosed small door of the operation box is opened with a special key to operate the three-position switch.

[0016] As a preferred technical solution of the present application, it also includes button password verification:

[0017] After the passenger enters the password, the car top board sends a verification request to the main control board through CAN communication;

[0018] The main control board compares the stored password combinations. If the verification is successful, the permissions for the controlled floors will be opened, and the display board will give a "passed" prompt in feedback.

[0019] As a preferred technical solution of the present application, a transparent window is provided on the operation box, and the position of the transparent window corresponds to the position of the display board.

[0020] As a preferred technical solution of the present application, when the passenger enters the password, if the input is not completed or is incorrect within the preset time, the display board automatically clears the entered value and displays an "error" prompt, and the password input process needs to be triggered again;

[0021] For the button password verification process, a time factor is introduced. Let the start time of the passenger entering the password be t0, the end time be t1, and the preset upper limit of the password input time be T. If t1 - t0 > T is satisfied, it is determined as overtime input, the display board automatically clears the entered value and displays an "error" prompt, and the password input process needs to be triggered again; if t1 - t0 ≤ T is satisfied, the password combinations are compared;

[0022] Assume that the password floor numbers stored in the main control board are FS1, FS2, and FS3, and the floor numbers entered by the passengers are FI1, FI2, and FI3. If and only if FS1 = FI1 and FS2 = FI2 and FS3 = FI3, the password verification is successful, the controlled floor permissions are opened, and a "pass" prompt is fed back on the display board.

[0023] As the preferred technical solution of this application, it also includes the error count, assuming that the number of times the passenger enters the wrong password is E, and the preset maximum number of errors is E max ; when E <E max If the input is wrong, the display panel will automatically clear the input value and display "error" prompt, and the password input process needs to be triggered again; when E=E max The elevator will be in a period of time T lock The password input function is locked internally, and the display panel shows the prompt "Too many incorrect inputs, temporarily locked".

[0024] As the preferred technical solution of this application, when setting the password, if the floors corresponding to the three floor buttons entered are F1, F2, and F3 respectively, the password verification must meet the following conditions: Assume that the highest floor that the elevator can reach is F max The lowest floor is F min , F min ≤F1, F2, F3≤F max ;The input floor number must satisfy F1≠F2≠F3.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the scheme of this application:

[0027] 1. This application does not require the installation of an additional password control box or IC controller, and directly uses the elevator's floor buttons as the password input medium, significantly reducing hardware investment and maintenance costs;

[0028] 2. This application uses a three-position switch to implement password setting, permission activation and deactivation. The operation process is simple and intuitive, and it supports dynamic adjustment of floor control status;

[0029] 3. This application is based on the modification of the standard elevator control box, without the need for non-standard panel design, and has strong versatility; the real-time display and flashing feedback of the floor buttons when the password is entered enhances the user interaction experience and safety;

[0030] 4. This application supports password reset function, meets the needs of permission change, and adapts to diverse application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present invention can be combined with each other.

[0037] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] For the embodiment, please refer to Figure 1 - Figure 2 , a method for controlling elevator riding with a floor button as a password, comprising the steps:

[0039] An operation box 6 provided in the elevator car, the operation box 6 has an enclosed small door integrating a three - position switch 5, an instruction board 3 and a display board 4; the instruction board 3 is connected to the car top board 2, and the car top board 2 is connected to a main control board 1. For the convenience of understanding, this application uses A to represent the elevator car and marks it in the figure. The car top board 2 is installed on the top of the elevator car;

[0040] The three - position switch 5 has a set position, an on position and an off position. When the three - position switch 5 is switched to the set position, by registering the floor button, the instruction board 3 of the operation box 6 records its value, and the input value is used as the floor registration password. At the same time, the input button will be lit and scrolled on the display board 4 in the order of input; the setting of the three - position switch 5 provides a simple and intuitive operation method. Users can easily switch the working mode of the elevator according to different needs. During the password setting process, the lighting of the input button and the scrolling display of the display board 4 provide multi - dimensional feedback information for users, enabling users to confirm the password they input in real time and enhancing the fun and interactivity of the operation;

[0041] After the elevator installation and commissioning are completed, turn the three-position switch 5 to the set position. At this time, input a high-level signal to the set mode IO port of the car top board 2. The car top board 2 interacts with the main control board 1 and enters the password setting mode. At this time, the display board 4 shows "---". Continuously input 3 floor buttons as the password, and the input floor values are displayed on the display board 4 in the order of input. After the setting is completed, the input buttons flash continuously, indicating that the setting is successful. The continuous input of 3 floor buttons needs to be completed within a specified time, such as three seconds. The specified time and the input quantity can reduce the hesitation and procrastination of users and improve the operation efficiency. The dynamic display of the display board 4 and the flashing prompt of the buttons enable users to clearly know each step and the final result of the password setting, avoiding errors and misunderstandings caused by unclear settings. After the password setting is successful, the main control board 1 encrypts and stores the password using AES-128.

[0042] If the three-position switch 5 is turned to the on position, the floor login is password-controlled. After the passenger inputs the corresponding password successfully, the controlled floors are registered. Implementing password control for floors significantly improves the safety and privacy of elevator use. For some floors with special security requirements, such as the confidential office areas of office buildings and the private floors of residential communities, only authorized personnel can enter by inputting the correct password, effectively preventing unauthorized personnel from entering and leaving at will and protecting the privacy and security of these areas.

[0043] If floor control is not required, turn the three-position switch 5 to the off position to open the floor control. In some special cases, such as holding large-scale events and conducting emergency rescues, it is necessary to quickly open the access rights to all floors. At this time, turning the three-position switch 5 to the off position can quickly achieve this purpose. This flexibility improves the emergency response ability and use efficiency of the elevator and reduces unnecessary restrictions and troubles.

[0044] Furthermore, the car top board 2, the main control board 1, and the command board 3 communicate with each other through CAN communication, and the command board 3 and the display board 4 communicate through MOD communication. MOD communication is Modbus protocol communication. CAN communication and MOD communication are mature industrial communication protocols. After a large number of practical verifications, they have good stability and reliability. The standardized protocols enable convenient communication and integration between devices of different manufacturers, reducing the cost of system development and maintenance.

[0045] Furthermore, when resetting the password, the three - position switch 5 needs to be turned to the set position. The floor buttons corresponding to the originally set password will light up. Double - click to cancel the numerical setting of a certain floor, and then re - enter the password value to be set. After the reset is completed, the three - floor buttons will keep flashing. This way of resetting the password is very convenient and fast. Users can modify the set password without complex operations. The lighting of the original password buttons and the double - click cancellation function make the operation more intuitive and easy to understand, reducing the operation difficulty for users. The flashing prompt after the reset allows users to confirm in time whether the password reset is successful, avoiding password setting errors caused by improper operations.

[0046] Furthermore, during the password setting process:

[0047] The three - position switch 5 triggers the car top board 2 to enter the set position through the IO point signal. The car top board 2 and the main control board 1 interact through the CAN communication protocol to complete password storage and permission configuration.

[0048] The display board 4 initially shows "---" and is replaced by the corresponding numerical values one by one according to the input order of the floor buttons, forming a dynamic visual interaction interface. This interaction method during the password setting process provides users with an immersive operation experience. The dynamic visual interface allows users to see their input situation in real time, enhancing the transparency and controllability of the operation. At the same time, the efficient interaction between the car top board 2 and the main control board 1 ensures the accurate storage of passwords and the correct configuration of permissions, improving the security and reliability of the system.

[0049] Furthermore, the enclosed small door of the operation box 6 is opened with a special key to operate the three - position switch 5. Normally, the small door is locked, and only the owner or professional personnel can open it to operate the three - position switch 5, ensuring the security of the password setting permission. Controlling the operation permission of the three - position switch 5 with a special key effectively prevents unauthorized personnel from modifying the password settings. This security measure provides a solid defense line for the elevator floor control system, protecting the security and stability of the system.

[0050] Furthermore, it also includes button password verification:

[0051] After the passenger enters the password, the car top board 2 sends a verification request to the main control board 1 through CAN communication.

[0052] The main control board 1 compares the stored password combination. If the verification is successful, it will open the permission for the controlled floor and feedback a "passed" prompt on the display board 4. The perfect password verification mechanism ensures that only passengers who enter the correct password can enter the controlled floor, improving the security and management efficiency of elevator use. The feedback prompt on the display board 4 allows passengers to understand the verification result in time, enhancing the passenger experience.

[0053] Further, a transparent window is provided on the control box 6, and the position of the transparent window corresponds to the position of the display board 4; the provision of the transparent window facilitates passengers to view the information on the display board 4 and improves the convenience of information acquisition.

[0054] Further, when a passenger enters a password, if the input is not completed or is incorrect within the preset time, the display board 4 automatically clears the entered value and displays an "error" prompt, and the password input process needs to be triggered again;

[0055] For the button password verification process, a time factor is introduced. Let the start time of the passenger entering the password be t0, the end time be t1, and the preset upper limit of the password input time be T. If t1 - t0 > T is satisfied, it is determined as overtime input, and the display board 4 automatically clears the entered value and displays an "error" prompt, and the password input process needs to be triggered again; if t1 - t0 ≤ T is satisfied, password combination comparison is performed;

[0056] Let the password floor numbers stored in the main control board 1 be FS1, FS2, FS3, and the floor numbers entered by the passenger be FI1, FI2, FI3. When and only when FS1 = FI1 and FS2 = FI2 and FS3 = FI3, the password verification is successful, the controlled floor permission is opened, and a "passed" prompt is fed back on the display board 4;

[0057] The time limit can prevent malicious attackers from cracking the password through long-term attempts and increase the difficulty of cracking; strict password comparison rules ensure that only passengers who enter the correct password can enter the controlled floor, reducing security vulnerabilities caused by similar or partially correct passwords; timely error prompts can guide passengers to perform correct operations again, improving the usage efficiency and user experience.

[0058] Further, it also includes error count statistics. Let the number of times the passenger enters the password incorrectly be E, and the preset maximum number of incorrect times be Emax; when E < Emax, if the input is incorrect, the display board 4 automatically clears the entered value and displays an "error" prompt, and the password input process needs to be triggered again; when E = Emax, the elevator will lock the password input function within a period of time Tlock, and the display board 4 displays a prompt of "too many incorrect input times, temporarily locked"; for example: the preset upper limit of the password input time is 10 seconds, the maximum number of incorrect times is 3 times, and the locking time Tlock is 5 minutes.

[0059] Error count statistics and locking mechanism further enhance the security of the elevator floor control system and effectively prevent malicious brute-force password cracking behavior; by restricting the number of incorrect inputs and locking the password input function, attackers can be forced to abandon the cracking attempt, protecting the security of the controlled floor. At the same time, this mechanism also reminds passengers to enter the password carefully to avoid elevator locking due to frequent incorrect inputs.

[0060] Further, when setting the password, if the floor numbers corresponding to the three floor buttons entered are F1, F2, and F3 respectively, the following conditions need to be met during password verification: Let the highest floor that the elevator can reach be Fmax, and the lowest floor be Fmin. Then Fmin ≤ F1, F2, F3 ≤ Fmax; the entered floor numbers need to satisfy F1 ≠ F2 ≠ F3, that is, the three floor numbers cannot be the same, so as to ensure the uniqueness and validity of the password. If there are duplicates among the three entered floor numbers, such as F1 = F2, F2 = F3, or F1 = F3, the display board 4 immediately displays 'Invalid Password' and clears the input, and the password needs to be set again.

[0061] These conditions ensure the uniqueness and validity of the set password, reducing security issues caused by duplicate or unreasonable passwords; restricting the range of floor numbers can ensure that the password is entered within the actual reachable floors of the elevator, avoiding invalid password settings; requiring the three floor numbers to be different increases the complexity and randomness of the password, improving the security of the password.

[0062] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or communicable with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Obviously, the embodiments described above are only a part of the embodiments of the present invention, rather than all embodiments. The accompanying drawings show the preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the present invention more thorough and comprehensive.
