Technical Field

[0001] The present invention relates to the technical field of elevator intelligent control, and in particular to an elevator intelligent control method and system based on Bluetooth technology. Background Art

[0002] Traditional elevator control methods mostly rely on physical buttons or card swiping systems. When taking the elevator, users need to walk to the elevator door in person and select the target floor by pressing buttons or swiping cards. Although this method is simple and direct, it has many inconveniences in actual application. For example, when the user is holding heavy objects or has physical disabilities, it may become difficult to operate the elevator. In addition, traditional elevator control methods also have certain limitations in terms of safety, convenience and intelligence. Summary of the invention

[0003] In view of this, the present invention proposes an elevator intelligent control method and system based on Bluetooth technology, which can effectively solve the defects of the existing technology that the safety, convenience and intelligence have certain limitations.

[0004] The technical solution of the present invention is achieved in this way:

[0005] An elevator intelligent control method based on Bluetooth technology, comprising:

[0006] Through Bluetooth technology, the elevator control system establishes a Bluetooth connection with the user's mobile device to achieve automatic pairing;

[0007] The elevator control system receives permission information from the permission management server, wherein the permission information is based on the user's Bluetooth device information or the application authorization on the mobile device;

[0008] Based on the received authority information, the elevator control system automatically determines whether the user has the authority to use the elevator, and executes the corresponding elevator operation instructions if the user has the authority;

[0009] Users directly control the operation of the elevator through an application on their mobile device or a Bluetooth device.

[0010] As a further optional solution of the elevator intelligent control method based on Bluetooth technology, the elevator control system broadcasts Bluetooth signals, waits for the user's mobile device to respond and establishes a Bluetooth connection, or actively scans surrounding Bluetooth devices and tries to establish a connection.

[0011] As a further optional solution of the elevator intelligent control method based on Bluetooth technology, the elevator control system establishes a Bluetooth connection with the user's mobile device through Bluetooth technology to achieve automatic pairing, specifically including:

[0012] When a user uses the elevator for the first time, he or she pairs the elevator Bluetooth module with the mobile device. At this time, the elevator operation control module obtains the elevator number and sends it to the mobile device. The user then uploads the elevator number and the Bluetooth MAC address of the mobile device to the cloud server for verification;

[0013] The cloud server verifies whether the user has the right to use the elevator. If the verification is successful, a specific key is returned to the mobile device. The mobile device and the operation control module are connected via Bluetooth and a pairing relationship is established.

[0014] The mobile device and the control module further confirm the pairing relationship by exchanging verification codes. The verification code is generated by the cloud server according to the serial number, key and matching times uploaded by the mobile device. If the verification codes generated by both parties are consistent, the pairing is confirmed to be successful, and the matching information and permission floors are saved to the user information storage unit;

[0015] In subsequent use, when the user's mobile device approaches the elevator, the elevator Bluetooth module will actively discover the paired mobile device and open the corresponding external call or floor permission according to the permission information in the user information storage unit, allowing the user to call the elevator normally or select the authorized floor.

[0016] As a further optional solution of the elevator intelligent control method based on Bluetooth technology, the elevator Bluetooth module detects the mobile device signal, specifically including:

[0017] The user sends a pairing request to the elevator Bluetooth module via a mobile device;

[0018] The elevator Bluetooth module determines the signal strength of the mobile device through the RSSI value;

[0019] When the RSSI value reaches the preset threshold, it is considered that the mobile device is close to the elevator, and a broadcast Bluetooth signal is sent to wait for the user's mobile device to respond and establish a Bluetooth connection.

[0020] As a further optional solution of the elevator intelligent control method based on Bluetooth technology, the verification code is generated by the cloud server according to the serial number, key and matching times uploaded by the mobile device, specifically including:

[0021] The cloud server concatenates the serial number, key, and matching times uploaded by the mobile device into a string;

[0022] The concatenated string is hashed using the MD5 algorithm to generate a hash value of a fixed length. The hash value is a unique identifier used to verify the uniqueness and integrity of the concatenated string.

[0023] As a further optional solution of the elevator intelligent control method based on Bluetooth technology, each time the verification code is generated, the cloud server and the operation control module will increase the number of matches by one before generating the verification code.

[0024] An elevator intelligent control system based on Bluetooth technology, comprising:

[0025] The Bluetooth communication module is configured in the elevator control system and is used to establish a Bluetooth connection with the user's mobile device to achieve automatic pairing;

[0026] A rights management interface, configured in the elevator control system, for receiving rights information from a rights management server, the rights information being based on the user's Bluetooth device information or the application authorization on the mobile device;

[0027] The authority judgment module is configured in the elevator control system and automatically judges whether the user has the authority to use the elevator based on the received authority information;

[0028] The elevator operation execution module is configured in the elevator control system and executes the corresponding elevator operation instructions when the user has the authority to use the elevator;

[0029] The user control interface is configured on the user's mobile device to directly control the operation of the elevator through an application or Bluetooth device.

[0030] As a further optional solution of the elevator intelligent control system based on Bluetooth technology, the authority judgment module also includes a user identity authentication function, which is used to authenticate the user when the user uses it for the first time or the authority information is changed.

[0031] As a further optional solution of the elevator intelligent control system based on Bluetooth technology, the user control interface also includes a user interface module for displaying information about the current status, available floors, and estimated arrival time of the elevator on a mobile device.

[0032] As a further optional solution of the elevator intelligent control system based on Bluetooth technology, the elevator operation execution module also includes a fault detection and alarm unit, which is used to detect faults and trigger an alarm mechanism during the operation of the elevator.

[0033] The beneficial effects of the present invention are as follows: users no longer need to rely on traditional physical buttons or card swiping methods, but can easily control elevators through mobile devices, which greatly improves the convenience and comfort of use. The application interface is friendly and the operation is intuitive. Users can check the elevator status, make reservations for elevators, etc. at any time, which improves travel efficiency.

[0037] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] refer to Figure 1 to Figure 2 , an elevator intelligent control method based on Bluetooth technology, comprising:

[0039] Through Bluetooth technology, the elevator control system establishes a Bluetooth connection with the user's mobile device to achieve automatic pairing;

[0040] The elevator control system receives permission information from the permission management server, wherein the permission information is based on the user's Bluetooth device information or the application authorization on the mobile device;

[0041] Based on the received authority information, the elevator control system automatically determines whether the user has the authority to use the elevator, and executes the corresponding elevator operation instructions if the user has the authority;

[0042] Users directly control the operation of the elevator through an application on their mobile device or a Bluetooth device.

[0043] In this embodiment, users no longer need to rely on traditional physical buttons or card swiping methods, but can easily control the elevator through mobile devices, which greatly improves the convenience and comfort of use. The application interface is friendly and the operation is intuitive. Users can check the elevator status, make reservations, etc. at any time, which improves travel efficiency. Users are authenticated and authorized through the authority management server to ensure that only authorized users can use the elevator, effectively preventing unauthorized access and abuse. The Bluetooth connection has a certain degree of security, and encrypted communication can prevent information leakage and illegal control. The elevator control system can receive and process authority information from the authority management server in real time, and automatically adjust the operating status of the elevator according to user authority, realizing intelligent management. The system can record user usage habits, optimize the elevator scheduling strategy through data analysis, and improve operating efficiency. Through mobile devices and applications, maintenance personnel can remotely monitor the operating status of the elevator, discover and handle faults in a timely manner, and improve maintenance efficiency and service quality.

[0044] Preferably, the elevator control system broadcasts a Bluetooth signal, waits for the user's mobile device to respond and establishes a Bluetooth connection, or actively scans surrounding Bluetooth devices and attempts to establish a connection.

[0045] In this embodiment, the elevator control system can choose to broadcast Bluetooth signals to passively wait for the user device to connect, or actively scan and try to connect to the user device. This two-way connection method greatly enhances the flexibility and adaptability of the system. Regardless of whether the user device is in an active search state or a passive response state, the system can effectively establish a Bluetooth connection, thereby improving the convenience of user interaction with the elevator. The user does not need to perform complex settings or operations, but only needs to ensure that the Bluetooth function of the mobile device is turned on and is in a discoverable state to establish a connection with the elevator control system. This seamless connection method reduces the user's waiting time and operation steps. The combination of broadcast and scanning mechanisms enables the elevator control system to discover user devices and establish connections more quickly, reducing delays and uncertainties in the connection process. In scenarios with high traffic, this efficient connection method can ensure timely response and scheduling of the elevator, thereby improving the operating efficiency of the elevator. Through the complementarity of broadcast and scanning mechanisms, the system can more comprehensively cover the surrounding Bluetooth devices, reducing connection failures caused by device omissions or signal interference. This redundant connection method enhances the stability and reliability of the system, and improves the overall performance of the elevator control system.

[0046] Preferably, the method of establishing a Bluetooth connection between the elevator control system and the user's mobile device through Bluetooth technology to achieve automatic pairing specifically includes:

[0047] When a user uses the elevator for the first time, he or she pairs the elevator Bluetooth module with the mobile device. At this time, the elevator operation control module obtains the elevator number and sends it to the mobile device. The user then uploads the elevator number and the Bluetooth MAC address of the mobile device to the cloud server for verification;

[0048] The cloud server verifies whether the user has the right to use the elevator. If the verification is successful, a specific key is returned to the mobile device. The mobile device and the operation control module are connected via Bluetooth and a pairing relationship is established.

[0049] The mobile device and the control module further confirm the pairing relationship by exchanging verification codes. The verification code is generated by the cloud server according to the serial number, key and matching times uploaded by the mobile device. If the verification codes generated by both parties are consistent, the pairing is confirmed to be successful, and the matching information and permission floors are saved to the user information storage unit;

[0050] In subsequent use, when the user's mobile device approaches the elevator, the elevator Bluetooth module will actively discover the paired mobile device and open the corresponding external call or floor permission according to the permission information in the user information storage unit, allowing the user to call the elevator normally or select the authorized floor.

[0051] In this embodiment, the user needs to perform pairing operation when using it for the first time, and upload the elevator number and Bluetooth MAC address to the cloud server for verification. This ensures that only authorized users can establish a connection with the elevator control system. The specific key returned by the cloud server further enhances the security of the connection and prevents unauthorized access. The pairing relationship is confirmed by exchanging verification codes, which further ensures the accuracy and reliability of the pairing process and avoids security risks caused by mispairing or malicious attacks. The user only needs to perform pairing operation when using it for the first time. In subsequent use, when the mobile device is close to the elevator, the elevator Bluetooth module will automatically discover the paired mobile device without the user performing additional operations. The elevator control system The corresponding external call or floor authority is opened according to the authority information in the user information storage unit, so that users can easily call the elevator or select the floor with authority, which improves the convenience and comfort of use; the elevator control system can identify the paired mobile devices and open the corresponding floor authority according to the user's authority information, avoiding unnecessary operation of the elevator and energy waste. Through intelligent scheduling and management, the system can more efficiently utilize elevator resources and improve the operation efficiency of the elevator; the user information storage unit saves matching information and authority floors, which is convenient for elevator managers to carry out subsequent maintenance and management work. The introduction of cloud servers makes the verification and management of user information more centralized and efficient, reducing maintenance costs.

[0052] It should be noted that the module of this solution is a dual-mode Bluetooth using classic Bluetooth and BLE Bluetooth. The MAC address of the classic Bluetooth of the mobile device is fixed, and the BLE Bluetooth address is variable. When the mobile device is used for the first time, it is connected to the module of this solution through the APP using classic Bluetooth. The module is connected to the MAC address of the mobile device. The module temporarily releases the BLE pairing mode for a period of time, and the APP then pairs with the module BLE through the BLE mode. After the pairing is successful, the module saves this BLE feature, which corresponds to the MAC address of the BT one by one.

[0053] The specific process of subsequent connection to the mobile device: The BLE module is in discoverable broadcast mode. When the mobile device approaches, it will actively connect to the paired BLE device. After the BLE module of this solution is connected to the mobile device, it will actively identify the BLE characteristics of the mobile device, the corresponding classic Bluetooth MAC address, and measure the BLE signal strength of the mobile device.

[0054] Preferably, the elevator Bluetooth module detects the mobile device signal, specifically including:

[0055] The user sends a pairing request to the elevator Bluetooth module via a mobile device;

[0056] The elevator Bluetooth module determines the signal strength of the mobile device through the RSSI value;

[0057] When the RSSI value reaches the preset threshold, it is considered that the mobile device is close to the elevator, and a broadcast Bluetooth signal is sent to wait for the user's mobile device to respond and establish a Bluetooth connection.

[0058] In this embodiment, the RSSI value is used to judge the signal strength of the mobile device, so as to more accurately judge whether the user is close to the elevator. When the RSSI value reaches the preset threshold, the elevator Bluetooth module will initiate a connection request, which avoids unnecessary Bluetooth connection attempts and improves the accuracy and efficiency of the connection. The user does not need to perform additional operations, but only needs to bring the mobile device close to the elevator, and the elevator Bluetooth module can automatically detect and respond. This automated interaction method reduces the user's waiting time and operation steps and improves the user experience. By judging the distance between the mobile device and the elevator through the RSSI value, the elevator Bluetooth module can maintain a low power consumption state when the user is not close, reducing unnecessary Bluetooth broadcasts and connection attempts, thereby reducing the energy consumption of the system. As a direct reflection of the signal strength, the RSSI value can reflect the communication status between the mobile device and the elevator Bluetooth module in real time. By monitoring the changes in the RSSI value, the system can promptly discover and solve potential communication problems and enhance the stability and reliability of the system.

[0059] Preferably, the verification code is generated by the cloud server according to the serial number, key and matching times uploaded by the mobile device, specifically including:

[0060] The cloud server concatenates the serial number, key, and matching times uploaded by the mobile device into a string;

[0061] The concatenated string is hashed using the MD5 algorithm to generate a hash value of a fixed length. The hash value is a unique identifier used to verify the uniqueness and integrity of the concatenated string.

[0062] In this embodiment, the cloud server concatenates the serial number, key and matching times uploaded by the mobile device into a character string. This process ensures that each generated verification code is based on unique input information. The concatenated character string is hashed using the MD5 algorithm to generate a fixed-length hash value as the verification code. The uniqueness of the verification code ensures its accuracy during the verification process, and the irreversibility of the MD5 algorithm enhances the security of the verification code, making it difficult for attackers to obtain the original input information through reverse engineering. Since the verification code is generated based on unique input information and the MD5 algorithm, during the verification process, the system only needs to compare the received verification code with the corresponding hash value stored in the cloud server. This comparison process is simple and efficient because the fixed length and uniqueness of the hash value make the comparison operation very fast and accurate. During the generation and verification of the verification code, the cloud server will record the relevant input information and the generated hash value, which can be used for troubleshooting and auditing purposes. If the verification fails or a security incident occurs, the system administrator can check these records to determine the root cause of the problem and take appropriate measures to solve the problem or prevent similar incidents from happening again.

[0063] It should be noted that the MD5 algorithm is used to perform hash processing on the concatenated string to generate a hash value of a fixed length. The specific steps include:

[0064] Use the concatenated string as the input of the MD5 algorithm;

[0065] Set up four 32-bit buffers (A, B, C, D), which are used to store intermediate results and final hash values. Use a set of fixed initial values ​​to initialize these four buffers.

[0066] If the length of the input string is not a multiple of 512 bits, you need to add enough padding bits (usually 1 bit '1' followed by several bits '0') to make the total length a multiple of 512 bits. After padding, you also need to add a 64-bit length information to indicate the length of the original data (in bits).

[0067] Divide the padded data into several 512-bit blocks (or message packets);

[0068] Each 512-bit block is processed in four rounds, each of which consists of 16 steps. The output of each round is used as the input of the next round, and the outputs of the four rounds are combined to produce the final hash value.

[0069] After four rounds of processing, the values ​​in the four buffers (A, B, C, and D) are merged into a 128-bit hash value.

[0070] Preferably, each time the verification code is generated, the cloud server and the manipulation control module will increase the number of matches by one before generating the verification code.

[0071] In this embodiment, after each successful match, the operation of adding one to the number of matches can effectively prevent repeated pairing. If an attacker attempts to bypass the verification mechanism by repeatedly sending the same pairing request, the system can identify and reject these repeated requests by checking the number of matches, thereby improving the security of the system; the number of matches is used as an input parameter for generating a verification code, and its change makes each generated verification code unique. This dynamic nature not only enhances the security of the verification code, but also makes it impossible for an attacker to use a verification code for illegal pairing in the future even if he intercepts it, because the verification code will continue to change with the increase in the number of matches.

[0072] An elevator intelligent control system based on Bluetooth technology, comprising:

[0073] The Bluetooth communication module is configured in the elevator control system and is used to establish a Bluetooth connection with the user's mobile device to achieve automatic pairing;

[0074] A rights management interface, configured in the elevator control system, for receiving rights information from a rights management server, the rights information being based on the user's Bluetooth device information or the application authorization on the mobile device;

[0075] The authority judgment module is configured in the elevator control system and automatically judges whether the user has the authority to use the elevator based on the received authority information;

[0076] The elevator operation execution module is configured in the elevator control system and executes the corresponding elevator operation instructions when the user has the authority to use the elevator;

[0077] The user control interface is configured on the user's mobile device to directly control the operation of the elevator through an application or Bluetooth device.

[0078] Preferably, the authority determination module further includes a user identity verification function, which is used to verify the identity of the user when the user uses the system for the first time or when the authority information is changed.

[0079] In this embodiment, user identity authentication is a key step to ensure that only authorized users can access or operate the elevator control system. By verifying the identity of the user, the system can prevent unauthorized access and operation, thereby protecting the safety of the elevator and passengers; the user identity authentication function in the authority judgment module can ensure that only verified users can obtain corresponding permissions, which helps prevent the abuse of permissions, such as unauthorized users trying to access or operate floors or functions that they should not access; the user identity authentication function enables the system to flexibly manage user permissions. When a user uses the system for the first time or the permission information changes, the system can confirm the identity of the user through identity authentication and adjust their permissions as needed. This dynamic management capability helps the system adapt to changing security needs and user behaviors.

[0080] Preferably, the user control interface further comprises a user interface module for displaying information on the current status, available floors and estimated arrival time of the elevator on the mobile device.

[0081] In this embodiment, by displaying the current status of the elevator, available floors, and estimated arrival time, the user interface module enhances the transparency of information, and users can make more informed decisions based on this information, such as choosing to wait for the current elevator or look for other elevators; when users can understand the status of the elevator in real time, they are more likely to make reasonable elevator choices, thereby reducing the load pressure of the elevator and optimizing the dispatch efficiency of the elevator.

[0082] Preferably, the elevator operation execution module also includes a fault detection and alarm unit, which is used to detect faults and trigger an alarm mechanism during the operation of the elevator.

[0083] In this embodiment, the fault detection and alarm unit can monitor the operating status of the elevator in real time. Once an abnormality or fault is detected, the alarm mechanism is immediately triggered, which helps to take timely measures to prevent the fault from further developing, thereby protecting the safety of passengers; through the fault detection and alarm unit, the system can respond as soon as the fault occurs, including sending an alarm signal to maintenance personnel, initiating emergency braking or taking other safety measures to minimize the impact of the fault on the elevator operation and passenger safety; the data provided by the fault detection and alarm unit can be used to optimize the maintenance plan of the elevator. The system can formulate a more accurate maintenance schedule based on the frequency and type of faults, thereby reducing unnecessary downtime and maintenance costs.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
