[0002] A door intercom system is an access control device used in residential, villa, and commercial premises, typically consisting of a door unit, an indoor terminal, and locks. This system allows users to communicate with visitors outside the door via voice or video intercom, and enables remote or local unlocking operations through the matching locks.

[0003] Existing door intercom systems typically use video or audio signal transmission technology to authenticate visitors and control door locks via an indoor terminal. Some systems support remote video intercom and door unlocking via a mobile app, allowing users to manage visitors from inside or remotely, thus improving ease of use.

[0004] Existing door intercom systems still have limitations in terms of operation and communication security: First, the operation of the system is mostly limited to indoor terminals or simple remote control, lacking support for multi-scenario linkage operations, such as voice interaction or diversified remote operations; second, there is a lack of optimization measures for complex communication environments (such as channel interference or long-distance operation), making it difficult to guarantee communication reliability and transmission efficiency; in addition, existing systems also have shortcomings in data transparency and traceability, making it difficult for users to understand unlocking records and operation details in a timely manner, increasing the complexity of system management.

Attached Figure Description

[0059] Figure 1 This is a system structure diagram of the present invention. Detailed Implementation

[0060] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Please see the appendix Figure 1 This invention provides an integrated smart door lock and door intercom system, comprising:

[0062] The door station control unit is used to receive user input signals and generate unlocking commands after processing the signals. The multiple input methods of the door station control unit enable the system to be used flexibly in various scenarios, meeting the needs of users for local and remote control. Through the signal optimization mechanism, the system can automatically select the optimal input path, improving the reliability and convenience of operation.

[0063] The wireless communication management unit is used to transmit the unlocking command generated by the door station control unit to the smart lock and return a feedback signal after the smart lock performs the operation. The dynamic switching function of the wireless communication management unit improves the stability and adaptability of communication, and can maintain the normal operation of the system in complex environments. Its low power consumption design and high-efficiency data transmission mechanism reduce system energy consumption and extend the service life of the equipment.

[0064] The smart lock actuator unit receives unlocking commands, executes the unlocking operation, and generates a feedback signal upon completion. Compatible with various lock types, it expands the system's application scenarios. Its modular design facilitates maintenance and upgrades, while a signal verification mechanism enhances operational security, ensuring reliable lock operation.

[0065] The dynamic signal routing and edge computing module parses and verifies user input signals locally, including command legality checks and user permission judgments. For complex signal parsing tasks, it combines locally stored data to generate unlocking operation commands, avoiding system unavailability due to network interruptions. Dynamic signal routing improves communication stability, and edge computing reduces dependence on the cloud, improving the system's real-time performance and privacy protection capabilities.

[0066] The security module is used to encrypt and verify unlocking commands and feedback signals. It effectively prevents the risk of unauthorized access or attacks to the system. Especially in remote control scenarios, its multi-layered security protection mechanism further enhances the security of user data and devices.

[0067] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the door station control unit collects and integrates user input signals through the following steps:

[0068] It receives key input signals. The key signals are detected by the microcontroller (MCU) through the high and low level changes triggered by the key, and then converted into standardized digital signals (e.g., logic "1" indicates key trigger, and "0" indicates no trigger). The key input method is intuitive and easy to use, and is suitable for scenarios without network or where users are accustomed to local operation. Its physical triggering mechanism has high reliability and can work effectively in low power mode.

[0069] The voice recognition module receives voice commands and collects voice signals through a microphone. After processing by the voice front end (including noise reduction and filtering), the voice data is converted into text or predefined commands using a voice recognition algorithm and then processed by the control unit. The voice recognition function allows users to unlock the door without touching the door station, which is especially suitable for users carrying items or with mobility impairments. Through the combination of local and cloud modes, the efficiency and accuracy of voice recognition are significantly improved.

[0070] The system receives an unlock request signal from the local mobile application, which then sends the unlock request via the local area network. The network module of the door station receives and decodes the signal, generates a standardized unlock command, and transmits it via the local area network, thereby improving data transmission efficiency and reducing dependence on external networks.

[0071] The system receives unlocking commands from a remote control application, which then sends the commands to a cloud server via the internet. The cloud server encrypts the commands and forwards them to the door station. The door station decodes the signals and generates standardized unlocking commands. This cloud relay mechanism enhances the system's cross-regional capabilities while ensuring the security of remote operations through encryption and verification mechanisms.

[0072] The system assigns weights to signals and calculates their levels to select the optimal signal for processing. The system calculates the signal level using the following formula:

[0073] P(I in ) = w b ·I b +w v ·I v +w a ·I a +w r ·I r

[0074] Wherein, P(I in ) represents the level of the input signal, w a w b w v and w r The weights of the signals from buttons, voice, local app, and remote app are respectively, satisfying w a +w b +w v+w r =1;

[0075] The multi-level computing and signal fusion mechanism ensures the stability and efficiency of the system in multi-input scenarios, while enhancing the flexibility of user operation and the adaptability of the system.

[0076] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the wireless communication management unit performs the following steps to achieve signal transmission:

[0077] The unlock command is appended with a timestamp and a random number to generate a signal packet. The timestamp is used to mark the generation time of the signal to prevent duplicate signals from being used. The random number is used to enhance the uniqueness of the signal packet and prevent the signal from being tampered with or forged. The addition of timestamp and random number enhances the uniqueness and integrity of the signal packet, effectively preventing replay attacks and data tampering. Data encryption protects the signal content and improves the security of the system during signal transmission.

[0078] Based on the communication distance, the system determines the transmission protocol and dynamically selects the communication protocol. This achieves a combination of efficient short-distance transmission and reliable long-distance transmission, ensuring the efficiency and adaptability of signal transmission while improving communication stability.

[0079] If the communication distance is less than the set threshold, short-range 433MHz communication is selected. 433MHz communication is a low-power, short-range wireless transmission technology that is suitable for direct communication between the door station and the smart lock. Its fast response capability of short-range communication improves the real-time linkage between the door station and the smart lock.

[0080] If the communication distance exceeds the set threshold, it switches to remote WiFi communication. WiFi communication extends the effective communication distance between the door station and the smart door lock, enabling the system to operate normally in long-distance scenarios. Through encrypted transmission and reception confirmation mechanisms, the system's security and transmission reliability are effectively guaranteed.

[0081] The reliable transmission of signal packets to the smart lock actuator ensures the correct operation of the smart lock actuator. Through dual encryption and reception confirmation, the communication security and operational reliability of the system are further improved.

[0082] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the smart door lock execution unit performs the unlocking operation through the following steps:

[0083] The system receives signal packets transmitted by the wireless communication management unit and decodes them into unlocking commands. The signal packet decoding adopts a modular design, supports data format compatibility with multiple communication protocols, and verifies data integrity during the decoding process to ensure that the signal packets are not damaged. The decoded commands are stored in a temporary buffer and executed only after their validity is verified. The data verification mechanism effectively prevents signal loss or misinterpretation, thus improving the accuracy of signal reception.

[0084] Verify the validity of the signal and determine whether there are duplicate timestamps or random number conflicts;

[0085] If the signal is valid:

[0086] For semi-automatic smart door locks, a fixed voltage is output to drive the clutch motor to complete the unlocking process;

[0087] For fully automatic smart door locks, the receiving unit will activate the smart door lock unlocking signal via a relay after receiving the unlocking information.

[0088] Specifically: Verify timestamp Ts: The system checks whether the timestamp is within the allowed time window range.

[0089] T current -T tolerance ≤T s ≤T current +T tolerance

[0090] Verify the random number Nr; the random number is stored in the historical record table Hrandom; if Nr exists in the record table, it is determined to be a repeating signal.

[0091]

[0092] When the signal is valid, the unlocking operation is performed; otherwise, the signal is discarded and the anomaly is recorded. The timestamp and random number verification mechanism ensures the uniqueness and legitimacy of the signal, eliminating replay attacks and forged signals. The dynamic management of the historical record table optimizes the system's storage and processing efficiency.

[0093] The output voltage of the clutch motor is provided by a built-in voltage regulator module to ensure that voltage fluctuations are within the allowable range. After the unlocking action is completed, the system automatically cuts off the voltage to avoid motor overload. A mechanical limit switch is configured to detect the completion status of the clutch motor's action and feed back the unlocking result to the system. The voltage regulation and limit design improve the system's operational stability and extend the service life of the clutch motor.

[0094] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the smart door lock execution unit generates a feedback signal through the following steps:

[0095] After performing the unlocking operation, the door lock status is detected and feedback data is generated. The limit switch is configured to automatically reset after the mechanical action is completed to detect whether the action is complete. The Hall sensor is calibrated to ensure that the status can be accurately judged at different stages of the unlocking action. At the same time, a status timeout judgment mechanism is set. If the door lock does not complete the action within a preset time, a failure status is reported. The status timeout judgment mechanism effectively improves the anomaly detection capability and avoids the situation where unlocking failure or equipment failure is not identified.

[0096] The feedback data is encoded and a timestamp and a random number are added to generate a feedback signal packet. The addition of the timestamp and random number makes the feedback signal packet unique and prevents replay, thus enhancing the security of the feedback process. At the same time, through encryption, the feedback signal packet has high confidentiality during transmission, preventing it from being intercepted or tampered with.

[0097] The feedback signal packet is transmitted to the door station control unit via the wireless communication management unit. If the feedback signal does not reach the door station control unit within the set time, the system will automatically retransmit the signal packet up to 3 times and record the transmission delay information. If the signal still does not arrive, the system will trigger an abnormal alarm and notify the user that the door lock status cannot be confirmed through the display screen or mobile application. The dynamic communication protocol selection optimizes the transmission efficiency of the feedback signal and avoids the loss of data packets during transmission.

[0098] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the security module implements data encryption and signal verification through the following steps:

[0099] When generating unlocking commands or feedback signals, the signals are encrypted using the AES-128 algorithm. AES-128 is a symmetric encryption algorithm that uses a fixed-length encryption key to encrypt the signals, thereby improving data confidentiality and preventing sensitive information from being stolen.

[0100] During signal transmission, the integrity and legitimacy of signal packets are verified. MAC verification and timestamp verification mechanisms ensure that signal packets are not tampered with or forged during transmission, thus improving data integrity.

[0101] To prevent key leakage, the encryption key is dynamically updated. This dynamic key update is based on a time synchronization mechanism and a key generation function, with the new encryption key K... new Generated via the key update formula:

[0102] K new =H(K) old ;T current )

[0103] Where: K new T is the current key; currentH is the system's current timestamp; H() is the hash function;

[0104] The triggering conditions for dynamic key updates include:

[0105] The system time interval reaches 24 hours;

[0106] If a potential threat to the communication channel is detected (such as a replay attack or MAC verification failure), the system will use the most recently successfully updated key when the update fails, and will also push a security warning to the user and suggest checking the network security status. If the update fails three times in a row, the system will temporarily disable the remote control function to ensure security.

[0107] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the wireless communication management unit performs the following steps to optimize channel management in short-range communication mode:

[0108] Real-time detection of channel noise power provides a reliable basis for channel selection and avoids signal transmission failure caused by communication interference.

[0109] Select the optimal channel based on noise power:

[0110] C optimal =argmin C P notse (Ci)

[0111] Among them, C optimal Optimal channel, P noise (Ci) represents the noise power of channel Ci;

[0112] Switching to a backup channel during channel interference and dynamically selecting the optimal channel improves the reliability and efficiency of signal transmission, especially in short-range communication environments with complex interference. At the same time, the low-latency design of channel switching ensures the real-time performance of the system and avoids a decline in user experience due to communication interruptions.

[0113] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the door station control unit realizes real-time display of the door lock status through the following steps:

[0114] The system receives feedback signals from the smart lock execution unit. After completing the operation, the smart lock execution unit sends the feedback signals to the door station via 433MHz, WiFi, and Zigbee communication protocols. The door station's wireless communication module listens to the signals in real time, captures and stores the feedback data.

[0115] The door lock status is extracted by decoding the feedback signal. The process of decoding the feedback signal ensures the accuracy of the door lock status information obtained by the door station and avoids display errors caused by signal tampering or incorrect parsing.

[0116] The door station display shows the door lock's locking status, unlocking status, or fault information. This intuitive display of the door lock status enhances the user's sense of control over the access control system, allowing them to understand the door lock's operating status without any additional operation.

[0117] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the system further includes the following extended functions:

[0118] Remote monitoring and operation can be achieved through WiFi or Zigbee communication modules. With WiFi communication modules, users can achieve remote management from different locations, improving the flexibility and convenience of the system. At the same time, data encryption and automatic reconnection mechanisms enhance the security and stability of remote communication.

[0119] The smart lock is unlocked via a Zigbee communication module operated by the door station. Specifically, after receiving a user's unlocking request (e.g., via button input or voice control), the door station generates a standardized unlocking command through its control unit. This command is first encrypted by the system security module to ensure its confidentiality and integrity. Then, the command is wirelessly transmitted via the door station's Zigbee module. The low power consumption of the Zigbee protocol makes it ideal for short-range communication scenarios, and its strong anti-interference capability allows for stable communication even in environments with multiple devices. The smart lock's Zigbee module monitors the communication channel in real time. Upon receiving the unlocking command signal, the module first verifies the signal to ensure it hasn't been tampered with. After successful verification, the smart lock's execution unit transmits the decoded unlocking command to the lock's control circuit module, driving the lock's actuator (such as a clutch motor or electromagnet) to complete the physical unlocking operation. By employing the Zigbee protocol, the power consumption requirements for communication between the door station and the smart lock are reduced, while ensuring system response speed.

[0120] The door lock is controlled by voice through a voice assistant interface. The door station control unit and the voice assistant communicate with each other via a local area network or cloud. The voice assistant converts the user's voice commands into text commands and sends them to the door station control unit, thus realizing a more natural interaction method. Users can control the door lock without relying on physical buttons or mobile phone operation.

[0121] By providing access to and querying unlock logs through a mobile application, the unlock log function offers users traceability of operation records, which helps improve the transparency and security of the system.

[0122] Please see the appendix Figure 1 In a preferred embodiment of the present invention, the dynamic signal routing and edge computing module selects the optimal communication path through the following steps:

[0123] Real-time detection of signal strength, interference noise, and communication load in the communication channel, and selection of communication protocol based on communication distance and channel status;

[0124] When the communication distance is short and the signal strength is high, choose 433MHz communication. When the communication distance is long or the channel load is low, choose WiFi communication. In multi-device scenarios, choose Zigbee communication to achieve device linkage.

[0125] Specifically:

[0126] The channel monitoring unit periodically scans the wireless spectrum, records the performance parameters of each channel, and stores them in a channel database. Each time a communication request is triggered, the module retrieves the latest channel information from the database and selects the optimal channel by calculating its priority. The priority formula is as follows:

[0127] P=α·RSSI-β·NoisePower-γ·NoisePower

[0128] Where P is the channel priority; α, β and γ are preset weight parameters used to balance the effects of signal strength, noise and load; the dynamic channel detection mechanism can quickly locate the best channel in complex wireless environments, ensuring the reliability and stability of communication, while the fast switching algorithm reduces the latency during protocol switching and improves the real-time response capability of the system.

[0129] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
