[0049] Figure 1 This is a flowchart of an automatic control method for intelligent garage doors in one embodiment. Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0051] This application provides an automatic control method for intelligent garage doors, applied to intelligent garage doors. The intelligent garage door includes a Bluetooth module and a state machine, and can establish a communication connection with the vehicle via the Bluetooth module. Figure 1 As shown, the automatic control method includes the following steps:

[0052] Step 102: Obtain periodic, continuous RSSI values ​​via Bluetooth module.

[0053] RSSI (Received Signal Strength Indicator) is used to determine the quality of a Bluetooth connection. It measures the distance between the transmitting and receiving points by analyzing the strength of the received RSSI signal. The core idea is to utilize the principle that Bluetooth signals weaken with distance. The RSSI value (usually negative, measured in dBm) decreases as the distance between the transmitter and receiver increases.

[0054] Therefore, the distance of a vehicle relative to a smart garage door can be determined using the RSSI value.

[0055] Step 104: Obtain the state of the smart garage door based on the state machine; the state of the smart garage door includes closed state, open state, opening in progress, closing in progress, and obstacle-stopped.

[0056] A state machine abstracts the behavior of a smart garage door into a finite number of states, events that trigger state transitions, and actions performed during state transitions. The state machine includes: CLOSED (closed), OPENING (open), OPEN (open), CLOSING (closed), and STOPPED_BY_OBSTACLE (obstacle closed).

[0057] Step 106: Determine the vehicle status based on the continuous RSSI value, and maintain or update the state machine based on the vehicle status and the status of the smart garage door.

[0058] When the RSSI value, representing the Bluetooth signal strength, becomes stronger, it indicates that the vehicle is approaching the smart garage door; conversely, when it becomes weaker, it indicates that the vehicle is moving away from the smart garage door. This is used to determine the vehicle's status.

[0059] Based on the current status of the smart garage door and the vehicle, it can determine whether to open or close the smart garage door and send corresponding control commands to the smart garage door's on / off controller. The state machine is then maintained or updated according to the smart garage door's status. For example, if a vehicle is approaching the smart garage door while it is closed, an open command needs to be sent, and the smart garage door's status should be switched from closed to open after it opens. If a vehicle is approaching the smart garage door while it is open, no control command needs to be sent; simply maintaining the open status of the smart garage door is sufficient.

[0060] This embodiment detects changes in the strength of Bluetooth signals to automatically open the doors when a vehicle approaches, eliminating the need for manual operation and achieving seamless parking, thus improving parking convenience and experience.

[0061] In one embodiment, determining the vehicle state based on consecutive RSSI values ​​includes: determining that the vehicle is in a first state when the RSSI value is greater than a first threshold for N consecutive times.

[0062] Customize system parameters, including the first threshold enterThreshold (e.g., -80 dBm) and the number of consecutive scans N (e.g., 3 times).

[0063] When RSSI > enterThreshold is detected N consecutive times, it is considered that the vehicle has been in the garage or near the garage door for an extended period. The vehicle state is then set to the first state, i.e., insideGarage = true. In the first state, it is ensured that the vehicle will not trigger accidental door opening when parked in the garage.

[0064] By employing a sliding time window mechanism to accumulate scan counts, misjudgments caused by signal fluctuations, temporary obstructions, and reflection interference are effectively filtered out, significantly improving system reliability.

[0065] In one embodiment, determining the vehicle state based on consecutive RSSI values ​​includes: determining the vehicle is in a second state when the RSSI value is less than a second threshold for N consecutive times; and determining the vehicle is in a second state when obtaining an RSSI value fails and the duration exceeds a time threshold.

[0066] This embodiment discloses two scenarios for determining if a vehicle is in the second state. In the first scenario, if N consecutive scans satisfy RSSI < exitThreshold, the vehicle is considered to have moved far from the garage, where exitThreshold is a custom second threshold (e.g., -95 dBm). In the second scenario, if no Bluetooth signal can be detected at all, and the duration exceeds the time threshold LOSS_TIMEOUT_MS (e.g., 20 seconds), the vehicle is considered to have left the Bluetooth detection range. When either of these scenarios occurs, the vehicle state is set to the second state, i.e., insideGarage = false. To distinguish between the two scenarios, the former is set to insideGarage = false (far), and the latter is set to insideGarage = false (loss).

[0067] Continuous signal detection is required to trigger the second state. This mechanism can effectively avoid misjudgments caused by temporary lag or brief scan failures.

[0068] In one embodiment, maintaining or updating the state machine based on the vehicle state and the smart garage door state includes: when it is determined that the vehicle is in a second state and the latest obtained RSSI value is greater than a first threshold, controlling the opening of the smart garage door and updating the state of the smart garage door.

[0069] This embodiment discloses an automatic opening mechanism for a smart garage door, which requires the following two conditions to be met simultaneously: 1. insideGarage = false; 2. The most recent valid RSSI scan satisfies RSSI > enterThreshold. At this time, it is determined that the vehicle is approaching the garage from the outside, i.e., the vehicle has a need to enter the garage, and the relay pulse is controlled to complete the door opening operation.

[0070] In one embodiment, maintaining or updating the state machine based on the vehicle status and the smart garage door status includes: starting a timer after the smart garage door status switches from open to open, and determining whether it is in an open blocking period; if not, when it is determined that the vehicle is in a second state and the latest obtained RSSI value is greater than a first threshold, controlling the opening of the smart garage door and updating the status of the smart garage door.

[0071] To ensure the safety of vehicles entering the garage, an opening blocking period (e.g., 13 seconds) is set. After the smart garage door is fully opened, it automatically enters a timing process. During the opening blocking period, the smart garage door blocks any opening or closing control commands and remains open to ensure that vehicles can safely enter the garage.

[0072] In this embodiment, the automatic opening of the smart garage door requires the following three conditions to be met simultaneously: 1. insideGarage=false; 2. The most recent valid scan RSSI satisfies RSSI > enterThreshold; 3. It is not within the door opening shielding period. After the conditions are met, the control triggers the relay pulse to complete the door opening operation and enters the door opening shielding timer process.

[0073] In one embodiment, controlling the opening of the smart garage door and updating its state includes: updating the smart garage door's state to "open" during the opening process; determining whether the smart garage door is fully open based on the Hall effect; if so, updating the smart garage door's state to "open" and starting a closing countdown.

[0074] This embodiment discloses the state machine state transition process during the door opening process. During the door opening process, the system enters the OPENING state; each time the door is fully opened, it enters the OPEN state and restarts the automatic closing countdown, whether it's the first opening or a subsequent opening after an obstacle bounces. The automatic closing countdown time is customizable, with a default of 30 seconds.

[0075] This embodiment uses the Hall effect to detect whether the door is fully open. The Hall effect refers to the phenomenon where, when current flows through a conductor (or semiconductor), if a magnetic field is applied perpendicular to the current direction, the charge carriers (electrons or holes) inside the conductor are deflected by the Lorentz force, resulting in a transverse voltage difference across the conductor. This voltage is the Hall voltage. The magnitude of the Hall voltage is related to the magnetic field strength, the current magnitude, and the Hall coefficient. Here, a Hall sensor and a permanent magnet are used together to detect whether the door is fully open. The installation position can be adjusted according to the opening method of the intelligent garage door.

[0076] In one embodiment, after the countdown to closing the door ends, the method further includes: controlling the closing of the smart garage door; during the closing process, updating the state of the smart garage door to "closing" and performing obstacle detection based on the Hall effect; when an obstacle is detected for the first time, controlling the cessation of closing the smart garage door and updating the state of the smart garage door to "obstacle stopped"; when an obstacle is detected for the second time, controlling the opening of the smart garage door and updating the state of the smart garage door to "open".

[0077] This embodiment discloses the state transition process of the state machine during the door closing process. During the closing process, the system enters the CLOSING state; once the door is fully closed, it enters the CLOSED state. Whether the door is fully closed is also detected using the Hall effect.

[0078] This embodiment also discloses the situation where an obstacle occurs during the door closing process. Obstacle detection can be performed using an infrared / photoelectric obstacle sensor. When an obstacle is detected, the door closing immediately stops, the smart garage door status is updated to STOPPED_BY_OBSTACLE, and after a certain delay (e.g., 300ms), the reverse door opening is automatically triggered. The reverse door opening is uniformly achieved by using an opening state machine and Hall effect detection to ensure full opening.

[0079] Obstacle detection prevents the door from closing and causing collisions or injuries when vehicles or people are underneath it, ensuring personal and property safety during vehicle entry and exit, and meeting garage door safety standards.

[0080] In one embodiment, the method further includes: in sentry mode, if the smart garage door is detected to be open and there is no authorized Bluetooth beacon nearby, pushing identity verification information to the terminal, and triggering an alarm or remote notification after the identity verification fails.

[0081] Sentry mode is used to detect unauthorized intrusions at night. During user-defined time periods (e.g., 11:00 PM to 7:00 AM), security monitoring is automatically activated. Detection includes using Hall effect sensors to check for abnormal door openings and using obstacle sensors to detect unauthorized entry of people or objects into the garage area (if the beam is obstructed). An alarm is triggered if an unauthorized door opening is detected during sentry mode, or if the obstacle sensor is continuously obstructed. Unauthorized methods include door opening via methods other than app, Bluetooth, or remote control.

[0082] In one embodiment, the control method uses an ESP32 as the main control chip, which integrates WiFi and Bluetooth dual wireless communication modes. The main control chip is connected to a relay module that drives the door motor switch, a Hall sensor that detects the door's open / closed state, an infrared / photoelectric obstacle sensor for door closing anti-pinch protection and sentry mode detection of illegal entry, a buzzer for sentry mode alarm output, and non-volatile storage for saving user configuration parameters.

[0083] In one embodiment, the main control chip connects to the cloud platform via WiFi wireless communication, and indirectly connects to the terminal through the cloud platform. The terminal can also connect to the smart garage door via a local network. The cloud platform's functions include receiving the smart garage door's status uploaded by the system, issuing commands to the smart garage door, synchronizing configurations, issuing alarm notifications, and updating device shadows. The device shadow synchronizes the smart garage door's status to the cloud in real time, supporting offline status queries by the terminal. The terminal's functions include: real-time monitoring of the smart garage door's status, one-button opening / closing, system parameter configuration, storing historical records, and voice control of the switch.

[0084] In one embodiment, simultaneous tracking of multiple Bluetooth devices (such as multiple vehicles or multiple family members) is supported. Each device corresponds to an independently managed data structure, including vehicle status, cumulative scan counter, time window start time, and permission for automatic door opening. The vehicle status includes unknown state, home-locked state (vehicle confirmed to be in the garage), home-unlocked state (vehicle leaving the garage area), and distance satisfied state (vehicle confirmed to have left, waiting to approach the door again). The home-locked state is considered the first state, and the home-unlocked state is considered the second state.

[0085] In one embodiment, control commands can be sent to the smart garage door via a terminal. If the triggering conditions for updating the state machine are not met, or if the state machine update determination and the control commands meet the preset safety policy, the smart garage door can be controlled to perform opening, closing, or status query operations according to the control commands.

[0086] The trigger condition for updating the state machine is determined by step 106, which determines whether to update the state machine based on the vehicle status and the status of the smart garage door. According to the above embodiment, if the current vehicle status and the smart garage door status correspond to controlling the smart garage door to automatically open or close, then the state machine updates the smart garage door status accordingly.

[0087] Preset safety strategies refer to measures to avoid conflicts with the automatic opening and closing program of the smart garage door. This can be achieved by setting the priority between the automatic opening and closing program and the control commands issued by the terminal. For example, the automatic opening and closing program of the smart garage door has a higher priority than the control commands issued by the terminal. When the vehicle status and the smart garage door status meet the conditions for automatic opening, the smart garage door opens automatically, and the opening action is unaffected by the control commands from the terminal. Alternatively, the control commands issued by the terminal have a higher priority than the automatic opening and closing program of the smart garage door. When the smart garage door enters a closing countdown after automatically opening, and the terminal issues a control command to keep the smart garage door open, the smart garage door stops the closing countdown and remains open until the terminal issues a closing control command. Preset safety strategies can also flexibly set the priority between the automatic opening and closing program and the control commands issued by the terminal. Under certain conditions, the former has a higher priority than the latter, while under other conditions, the latter has a higher priority than the former.

[0088] This embodiment integrates the state machine, multiple control sources, and safety strategies into a single decision-making system, thereby improving control flexibility and parking convenience while ensuring safety.

[0089] In one embodiment, the terminal can issue commands via voice. The terminal collects voice signals through a microphone array, converts the voice signals into corresponding text content using speech recognition technology, performs intent recognition using natural language understanding technology, and generates control commands based on the parsed intent.

[0090] This invention provides an automatic garage door control method. By detecting changes in Bluetooth signal strength, it enables automatic door opening when a vehicle approaches, automatic door closing after the vehicle leaves, and automatic door opening upon re-triggering. Simultaneously, a false trigger protection mechanism is designed. When a vehicle is parked inside the garage, even if the RSSI value occasionally drops or the connection is briefly lost, the insideGarage indicator remains true, preventing accidental door opening. Only continuous weak signals or prolonged complete disconnection are considered a genuine departure. Therefore, this invention achieves a convenient and highly safe parking method through automatic garage door control.

[0091] The entire logic can run on any controller with Bluetooth functionality, simulating the original door operator buttons through relay dry contacts, adapting to different brands of garage doors, and has wide applicability.
