[0002] As an indispensable and important part of modern intelligent buildings and public facilities, automatic door systems are widely used in residential houses, commercial buildings, hospitals, schools, shopping centers and other places. Traditional automatic door systems are mainly composed of sensors, control units, drive mechanisms and display modules. Sensors usually use infrared or microwave technology to detect the approach of people, thereby triggering the opening and closing of doors. However, existing sensors still have certain deficiencies in sensitivity and false detection rate. Especially in complex environments, they are easily disturbed by external factors such as light and temperature, resulting in false operations or missed detections, reducing the reliability of the system.

[0023] Figure 1 It is a logical structure diagram of the present invention;

[0024] Figure 2 The figure is a flow chart of the method steps of the present invention. DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0027] See also Figure 1-Figure 2 , the following describes an intelligent sensing door control system and method according to some embodiments of the present invention.

[0028] The embodiment of the first aspect of the present invention provides an intelligent sensing door control system. In some embodiments of the present invention, such as Figure 1 As shown, the control system is arranged on the door body and is used for opening and closing the door body, including:

[0029] The sensor module is arranged on the outdoor side of the door body; the sensor module is used to obtain identification information of people approaching the door body.

[0030] The control module is used to match the currently acquired identification information with the pre-stored identification information, and if they match, generate control data for starting the door lock.

[0031] The display module is arranged on the outdoor side and the indoor side of the door body; the display module is used to generate alarm information according to the matching result.

[0032] The communication module exchanges data with the network device located indoors; the control module obtains the current environmental data of the sensor module through the communication module, and adjusts the sensing range and / or sensitivity of the sensor module according to the environmental data. The environmental data includes the current weather conditions, time, and lighting conditions of the space where the sensor module is located.

[0033] The present invention provides an intelligent induction door control system, in which the sensor module is installed on the outdoor side of the door body, and its main responsibility is to detect and obtain the identification information of the person approaching the door body; the sensor module monitors the area in front of the door in real time through a variety of sensing technologies (such as infrared sensors, microwave sensors, ultrasonic sensors or capacitive sensors), identifies and detects the person approaching the door body. These sensors can capture the movement, heat change or reflection signal of the human body, so as to determine whether there is a person approaching; after detecting the person, the sensor module will further obtain the identification information of the person. This can be achieved by reading the data of a smart device (such as a mobile phone Bluetooth signal, RFID card or other identity recognition device). For example, when a user carries a smart phone close to the door body, the sensor module can identify and record the unique identifier (such as MAC address) of the mobile phone through the Bluetooth signal. For example, the intelligent induction door control system is installed at the entrance of an office building. When an employee carries a mobile phone close to the door body, the sensor module detects the Bluetooth signal of the mobile phone and obtains its unique identifier, and then passes the information to the control module for further processing. As the perception layer of the system, the sensor module is responsible for real-time monitoring and obtaining the information of the person entering the door body area, and is the basis of the entire intelligent induction door system, ensuring that the system can accurately perceive and identify users.

[0034] The control module receives the currently acquired identification information transmitted by the sensor module and compares it with the pre-stored identification information pre-stored in the system database. The pre-stored identification information includes the unique identifier of the authorized person, the authority level, etc. If the currently acquired identification information matches the pre-stored information successfully, the control module will generate control data to start the door lock and instruct the door lock system to perform the door opening operation. If the match fails, no control data will be generated and the door lock will remain closed. When the sensor module obtains the identification information of the employee's mobile phone, the control module will search the database to see if the identifier exists and has the right to open the door. If the match is successful, the control module will send a door opening command to the door lock system, and the door lock will be unlocked and opened automatically to allow the employee to enter; as the decision-making layer of the system, the control module is responsible for processing and analyzing the data provided by the sensor module to ensure that only authorized personnel can pass through the access control system. This process ensures the security and effectiveness of the access control system.

[0035] The display module is installed on the outdoor and indoor sides of the door body so that users can view the system status and alarm information at different locations; the display module generates corresponding alarm information or status prompts based on the matching results of the control module. For example, when the identification information matches successfully, the display module can display the information "Welcome" or "Authorized entry"; when the match fails, it can display alarm information such as "Unauthorized" or "Please contact the administrator"; the display module can also display the current status of the door, such as "Door is opening", "Door is closed", etc., to help users understand the operating status of the door control system in real time. At the door of the office building, when an employee approaches the door body, the display module on the outdoor side will display "Welcome, Li Hua", and the display module on the indoor side will display "Door is open". If an unauthorized person tries to enter, the display module on the outdoor side will display "Unauthorized entry, please contact security", and the display module on the indoor side will keep the door closed.

[0036] As the visualization layer of the system, the display module provides user interface feedback, enhances the interactivity and user experience of the system, and enables users to understand the operating status and processing results of the door control system in a timely manner.

[0037] The communication module is responsible for data interaction with the network devices located indoors. Through wireless communication technologies (such as Wi-Fi, Bluetooth, Zigbee, etc.), the communication module transmits the environmental data and identification information obtained by the sensor module to the indoor network devices, such as the central control server or the intelligent management platform; the control module obtains the current environmental data of the sensor module through the communication module, and dynamically adjusts the sensing range and sensitivity of the sensor module based on these data. Environmental data includes the current weather conditions, time, and lighting conditions of the space where the sensor module is located. In the same high-end office building, the communication module transmits the real-time weather conditions (such as rainy days, sunny days), current time (such as daytime, night), and lighting conditions of the door area obtained by the sensor module to the indoor central control server. The central control server instructs the control module to adjust the sensing range and sensitivity of the sensor module based on these environmental data. For example, on rainy days, the sensitivity of the sensor module may be increased to more accurately detect passing people; when there is sufficient light during the day, the sensing range may be appropriately reduced to reduce false detection. As the communication bridge of the system, the communication module ensures the smooth transmission of information between modules, and realizes intelligent dynamic adjustment by obtaining environmental data, thereby improving the adaptability and accuracy of the system.

[0038] In summary, the problem that the sensors of the traditional automatic door system are easily disturbed by external factors such as light and temperature in complex environments, resulting in malfunction or missed detection, and reducing the reliability of the system, is solved. The present invention can dynamically adjust the sensing range and sensitivity of the sensor by integrating multiple sensing technologies (such as infrared sensors, microwave sensors, ultrasonic sensors, etc.) in the sensor module, and combining the real-time acquisition and analysis of environmental data by the control module. For example, when the system detects that the current ambient light is strong or the weather is bad (such as heavy rain or heavy snow), the control module will automatically reduce the sensing range of the sensor and reduce the sensitivity to reduce the interference of environmental noise on the sensor, thereby improving the accuracy and reliability of personnel detection. In addition, the combination of multiple sensing technologies can complement each other's shortcomings, further improve the overall detection accuracy, and reduce the incidence of false detection and missed detection; it has the advantages of reducing false operation and missed detection, ensuring that the door body responds to the right person at the right time; users can pass through the door body smoothly under various environmental conditions, avoiding unnecessary waiting and operation.

[0039] The problem that the traditional automatic door system has relatively single functions, is mainly responsible for receiving sensor signals and driving the opening and closing of the door, lacks intelligence and multi-functional integration, and is difficult to meet the needs of modern intelligent buildings. The intelligent induction door control system of the present invention realizes multi-functional intelligent control through the collaborative work of the control module and the communication module. For example, the control module can not only perform personnel identity authentication and door lock control, but also interact with the indoor network equipment through the communication module to obtain current environmental data (such as weather conditions, time, lighting conditions, etc.), and dynamically adjust the sensing range and sensitivity of the sensor accordingly. In addition, the display module synchronously displays the alarm information and the status of the door on the outdoor and indoor sides of the door body, further enhancing the interactivity and intelligence level of the system; it can adapt to different usage scenarios and environmental conditions, and is suitable for commercial buildings, hospitals, schools and other places; through the integration of network equipment, managers can monitor the operating status of the access control system and the records of personnel entering and exiting in real time, which is convenient for management and maintenance.

[0040] In any of the above embodiments, the control module controls the door lock through the driving mechanism, and the intelligent sensing door control system also includes:

[0041] The broadcast module is arranged on the outdoor side; the driving mechanism is connected to the door lock and the control module. When the driving mechanism controls the door lock, the broadcast module generates an anti-phase signal that matches the noise signal generated by the driving mechanism to suppress the noise signal of the driving mechanism and improve the quietness of the system operation.

[0042] In this embodiment, the broadcast module is installed on the outdoor side of the door body and is connected to the drive mechanism and the control module. Its main responsibility is to suppress the propagation of noise by generating an anti-phase signal that matches the noise signal generated by the drive mechanism when the drive mechanism controls the door lock, thereby improving the quietness of the system operation. When the drive mechanism (usually an electric motor or a stepper motor) starts or closes the door body, a certain amount of mechanical noise will be generated. The broadcast module detects these noise signals and generates corresponding anti-phase signals to achieve active noise control (Active Noise Cancellation, ANC). After the anti-phase signal is superimposed on the original noise signal, the opposite phase is achieved to achieve the effect of mutual cancellation, thereby significantly reducing the perception of noise. The broadcast module can monitor the noise level generated by the drive mechanism in real time, and dynamically adjust the amplitude and frequency of the anti-phase signal according to the monitoring results to ensure the optimization of the noise suppression effect. This adaptive adjustment mechanism enables the system to maintain low noise operation under different operating conditions. The broadcast module can not only process the noise from the drive mechanism, but also adjust the noise suppression strategy according to environmental data (such as weather conditions, time, and light conditions). For example, at night or in a quiet environment, the system will pay more attention to noise suppression to reduce interference with the surrounding environment; during the day or in a noisy environment, the system can appropriately adjust the intensity of noise suppression to balance noise control and system response speed.

[0043] Specifically, the intelligent induction door control system of the present invention is installed at the entrance of the office building. Whenever an authorized employee passes through the door body, the drive mechanism starts and the electric door slowly opens. During this process, the mechanical noise generated by the drive mechanism may affect the surrounding office environment. The broadcast module detects these noise signals in real time and immediately generates an anti-phase signal, which is emitted through the speaker and superimposed with the original noise to cancel each other out, making the opening and closing process of the door body almost silent, maintaining a quiet working atmosphere in the office building.

[0044] Specifically, an intelligent sensing door control system is installed on the door of the hospital ward to ensure a quiet environment in the ward. Whenever medical staff or visitors pass by, the drive mechanism starts to open the door, which may generate noise. After the broadcast module senses these noises, it generates an anti-phase signal to suppress the spread of noise, ensure that patients in the ward are not disturbed, and improve the comfort and professionalism of the medical environment.

[0045] Specifically, an intelligent induction door control system is deployed at the entrance and exit of the library to ensure a quiet reading environment in the library. When readers enter or leave, the drive mechanism controls the opening and closing of the door, and the broadcast module suppresses noise through an inverted signal to ensure that the quiet atmosphere in the library is not disturbed, while providing readers with a smooth entry and exit experience.

[0046] Furthermore, the step of generating the anti-phase signal includes:

[0047] Perform spectrum analysis on the collected noise signal N(t), extract the main frequency, amplitude and phase information, and use fast Fourier transform (FFT) to convert the time domain signal N(t) into the frequency domain signal N(f), specifically:

[0048]

[0049] Where f is the frequency, usually expressed in Hertz (Hz), describing the frequency component of the signal; N(t) is the collected time domain noise signal, representing the noise intensity that changes over time; N(f) is the frequency domain noise signal, representing the intensity distribution of the noise signal at different frequencies; t is time, representing the time series of the noise signal; j is an imaginary unit, representing the complex part in the Fourier transform; represents the Fourier transform operation; e is the difference between the expected output and the actual output; π is a mathematical constant, approximately equal to 3.14159.

[0050] The frequency domain signal of the antiphase signal is obtained based on the frequency domain signal N(f) of the noise signal, and is rewritten into a time domain signal taking into account the environmental data, specifically:

[0051] R′(t)=-α(E)·A m cos(2πβ(E)f m t+φ m )

[0052] Among them, α(E) is the environmental impact coefficient, which is used to adjust the amplitude of the anti-phase signal and depends on the environmental data; β(E) is the environmental impact coefficient, which is used to adjust the frequency of the anti-phase signal and depends on the environmental data; R′(t) is the adjusted anti-phase signal; φ m is the phase of the noise signal; f m is the main frequency of the noise signal; A m is the amplitude of the noise signal; cos is a trigonometric function; the vector of environmental data is E={W, T, L}, and W is the weather condition including sunny, rainy and snowy days; T is the hour of the day, distinguishing between day and night; L is the ambient light intensity, which can be obtained through the light sensor.

[0053] Determine the superposition state of the anti-phase signal and the noise signal, and optimize toward zero:

[0054] S(t)=N(t)+R′(t)=A(t)cos(2πf(t)t+φ(t))-α(E)·A m cos(2πβ(E)f m t+φ m )

[0055] Among them, S(t) is the superimposed feedback signal; A(t) is the instantaneous amplitude of the noise signal; f(t) is the instantaneous frequency of the noise signal; φ(t) is the instantaneous phase of the noise signal.

[0056] In any of the above embodiments, the identification information includes fingerprint information, facial information and device information of the mobile device, and the smart induction door control system also includes a storage module, which is used to store the identification information and bind the fingerprint information and / or facial information to the device information. The binding of facial information and device information includes people in a pre-set list and strangers who are not in the list.

[0057] In this embodiment, the identification information and storage module undertakes the key tasks of personnel identification and data management. The identification information mainly includes fingerprint information, facial information and device information of the mobile device, which are securely and effectively stored and managed through the storage module. The storage module is not only responsible for saving the identification information, but also builds a multi-authentication mechanism by binding the fingerprint information and / or facial information with the device information, thereby greatly improving the security and recognition accuracy of the system.

[0058] First, the collection and storage of fingerprint information is completed through the fingerprint reader. When each authorized person registers, the system will collect their unique fingerprint image and convert it into digital feature data. These fingerprint feature data are encrypted and stored in the storage module to ensure the confidentiality and tamper-proof of the data. The collection of facial information is achieved through the high-definition camera installed in the access control system. The system uses facial recognition algorithms to convert the captured facial images into comparable feature vectors, which are also encrypted and stored. The device information of mobile devices, such as the MAC address or device ID of smartphones, is collected in real time through Bluetooth or Wi-Fi modules and stored in the storage module. This device information is not only used to identify the user carrying the device, but also serves as the basis for the second layer of identity authentication to prevent the device from being stolen or forged.

[0059] One of the core functions of the storage module is to bind fingerprint information, facial information and device information. This binding process is achieved by establishing an association table in the storage module to ensure that each user's multiple identity information is associated with the same user record. For example, during the registration process of an employee, his fingerprint information, facial features and mobile phone MAC address will be entered and bound to the same user ID. When the employee tries to enter the office building, the system will verify his fingerprint and mobile device information at the same time. Only when the two match successfully will the system authorize the door to open. This multiple verification mechanism greatly enhances the security of the system and avoids the security vulnerabilities that may be caused by a single verification method.

[0060] In addition, the storage module is also responsible for managing and maintaining the preset authorization list. The authorization list includes all the information of people who are authorized to enter a specific area, and the system will dynamically adjust it according to the permission level and access time period. For example, during the day, the system allows more employees and visitors to pass through the access control system, while at night, only specific high-authority personnel are allowed to enter. This dynamic permission management not only improves the flexibility of the system, but also ensures that security needs are met at different time periods.

[0061] In any of the above embodiments, the control module has an automatic unlocking mode and a manual unlocking mode built in, and the sensor module includes:

[0062] The capacitive sensor is arranged on the handle of the door body; the capacitive sensor is used to obtain the fingerprint information of the person to execute the manual unlocking mode.

[0063] The image sensor is arranged on the outdoor side; the image sensor is used to obtain facial information of a person to execute the automatic unlocking mode.

[0064] Wherein, when switching between the automatic unlocking mode and the manual unlocking mode, the broadcasting module generates a sound signal.

[0065] In this embodiment, the control module is the core of the entire intelligent induction door control system, and it is responsible for adjusting and switching different unlocking modes. The module has two built-in unlocking modes: automatic unlocking mode and manual unlocking mode. Specifically:

[0066] Automatic unlocking mode: This mode mainly relies on facial recognition technology. When a person approaches the access control system, the system collects facial information through the image sensor and matches it with the pre-stored facial information. Once the match is successful, the control module will trigger the unlocking operation and automatically unlock the door without additional operation.

[0067] Manual unlocking mode: This mode relies on the capacitive sensor to collect the fingerprint information of the person. When the user touches the door handle, the capacitive sensor will obtain and identify their fingerprint information. If the fingerprint matches the pre-registered fingerprint information, the control module will perform the unlocking operation. Manual unlocking mode is usually used when the user prefers to verify through fingerprint recognition, or in special circumstances (such as when image recognition fails or the light is insufficient).

[0068] The capacitive sensor is installed on the door handle and is specifically used to detect whether a person has touched the handle. Its main function is to obtain the fingerprint information of the person for manual unlocking mode. The capacitive sensor determines the presence of a fingerprint by measuring the change in capacitance. When the user touches the door handle, the unique capacitive characteristics of the fingerprint trigger the sensor's reaction. The sensor converts the fingerprint image into a digital signal and matches it with the fingerprint information stored in the system. If the match is successful, the control module will send an unlock signal to open the door.

[0069] The image sensor is installed on the outdoor side of the door to collect facial information of the person and execute the automatic unlocking mode. The sensor is usually a high-definition camera that can capture the details of the person's face and analyze it through a facial recognition algorithm. By comparing it with the facial database stored in the system, the image sensor can verify the identity of the person. Once the match is successful, the control module will automatically issue an unlocking command.

[0070] When switching between automatic unlocking mode and manual unlocking mode, the broadcast module generates a sound signal to inform the user of the current system status and ensure that the user can clearly perceive the mode switch. The sound signal of the broadcast module can be a different tone or rhythm to distinguish between automatic mode and manual mode. For example, in automatic unlocking mode, the broadcast module may play a soft "prompt sound", while in manual unlocking mode, a more obvious "confirmation sound" may be played to remind the user that the system is entering manual mode. The broadcast module not only makes a sound when the mode is switched, but also generates corresponding sound signals according to other system states. For example, when the system recognizes an unknown person or an incorrect fingerprint, the broadcast module will issue a warning sound to prompt the administrator to check the security of the access control system.

[0071] Specifically, the sensor type uses adjustable sensors, which usually have the hardware ability to adjust the sensitivity and sensing range. A variable gain amplifier (VGA) is integrated in the sensor circuit to adjust the gain of the sensor signal, thereby affecting the sensitivity; the sensing range is changed by adjusting the voltage, frequency or signal strength. The control module issues adjustment instructions to change the working mode of the sensor hardware to increase or decrease the sensing range or sensitivity. The working mode of the sensor can be dynamically adjusted by setting the threshold.

[0072] In any of the above embodiments, the control module controls the activation and deactivation of the sensor module, the display module, the communication module and the broadcast module through an energy optimization algorithm, so as to increase the battery life of the system without changing the battery capacity of the system.

[0073] In this embodiment, the algorithm takes the current remaining power of the battery and the power consumption data of each module as input, and determines which modules need to remain turned on at a certain moment and which modules can enter standby or sleep mode by setting the priorities of different modules. For example, in a low-flow environment, the sensing function of the sensor module can reduce the operating frequency or enter standby mode, while in a high-flow environment, the sensor module needs to maintain a high frequency of operation. In addition, the algorithm will also make intelligent adjustments based on environmental factors such as time period and light intensity. At night or in a dimly lit environment, the brightness of the display module can be automatically adjusted, and the frequency of use of the communication module can also be reduced, thereby further reducing overall energy consumption.

[0074] According to the calculation results of the energy optimization algorithm, the control module starts or shuts down each module through control signals. For example, when there is no need to transmit data or perform face recognition, the communication module and image sensor can enter a dormant state. When a person approaches or the door lock needs to be opened, the sensor module and display module will be activated. The broadcast module is also controlled by the energy optimization algorithm, and only when necessary will a warning or operation confirmation signal be issued, thereby further reducing the overall power consumption of the system.

[0075] In any of the above embodiments, the communication module includes a first communication unit located on the indoor side and a second communication unit located on the outdoor side.

[0076] The first communication unit is used to obtain environmental data.

[0077] The second communication unit is used to connect to the mobile device of the person and generate the first connection information, and the control module starts the display module and the sensor module according to the first connection information. Since the sensing distance of the second communication unit for the mobile device is much higher than the sensing distance of the sensor for the person, the display module and the sensor module are started through the first connection information, and the sensor module can be started in advance when the person is not approaching, so as to speed up the recognition speed.

[0078] In this embodiment, the first communication unit is installed on the indoor side of the smart induction door control system, and is mainly responsible for obtaining environmental data. Environmental data include but are not limited to light intensity, temperature, humidity, air quality, noise level, etc., which are of great reference value for the energy optimization and adjustment of the operation strategy of the system. The second communication unit is installed on the outdoor side of the smart induction door control system, and is mainly responsible for connecting the personnel's mobile device and generating the first connection information. The unit uses wireless communication technology (such as Bluetooth, NFC, Wi-Fi Direct, etc.) to establish a connection with the user's mobile device, thereby realizing identity recognition and system interaction.

[0079] After the control module receives the first connection information generated by the second communication unit, it intelligently starts the display module and the sensor module based on this information. Since the perception distance of the second communication unit to the mobile device is usually much higher than the perception distance of the sensor module to the person, the system can pre-start the sensor module before the person is completely close to the access control system. This mechanism significantly improves the response speed and accuracy of identity recognition. Start the sensor module in advance: Through the first connection information, the control module can activate the sensor module (such as image sensor, fingerprint reader, etc.) in advance before the person reaches the sensing distance, and prepare for rapid identity authentication; after the display module is started in advance, it can display the recognition status or prompt information in real time, improving the user experience and the interactivity of the system.

[0080] Specifically, the hardware components of the communication module include: the first communication unit (indoor side), sensor integration module: integrating multiple environmental sensors, such as light sensors, temperature and humidity sensors, noise sensors, motion sensors, etc., wireless communication interface: supporting Wi-Fi, Zigbee or other low-power wireless communication protocols for data transmission to the control module, microcontroller (MCU): responsible for the collection and preliminary processing of sensor data, power management module: ensuring stable power supply of the communication unit under different working conditions, including batteries and power converters; the second communication unit (outdoor side), wireless communication module: supporting Bluetooth, NFC, Wi-Fi Direct and other protocols, used to scan and identify mobile devices, antenna design: optimizing antenna layout to expand the perception range and improve the stability and distance of device connection, processor: responsible for scanning, identification and generation of connection information of mobile devices, security module: integrated encryption chip to ensure the secure transmission of mobile device connection information.

[0081] The hardware components of the control module include: main controller: a high-performance microprocessor or embedded system, responsible for the coordination and control of the entire system; storage module: used to store environmental data, connection information and pre-stored identification information, usually using flash memory or solid-state hard disk; display module interface: a control interface connected to the display screen, supporting brightness adjustment and status display functions; sensor module interface: a control interface connected to various sensors, supporting dynamic adjustment of sensing range and sensitivity; power management unit: ensures stable power supply to the main controller and other modules, including a battery management system (BMS) to extend battery life.

[0082] The display module includes a high-brightness LED display: it supports dynamic brightness adjustment to ensure that information is clearly visible under different lighting conditions and allows users to perform manual operations, such as touching to start manual unlocking mode.

[0083] The sensor module includes an image sensor: a high-resolution camera for facial recognition and environmental monitoring; a fingerprint sensor: a capacitive sensor integrated on the door handle for fingerprint recognition; a motion sensor: detects the approach and movement of people, and adjusts the sensing range and sensitivity.

[0084] The broadcast module includes a speaker: a high-quality speaker used to play prompt tones and alarm tones; an audio processing unit: responsible for the generation and playback control of audio signals.

[0085] Specifically, the embedded operating system of the control module: such as FreeRTOS, Embedded Linux, is used to manage hardware resources and task scheduling. Wireless communication protocol of the communication module: the first communication unit communicates with the main controller through Wi-Fi or Zigbee to transmit environmental data; the second communication unit communicates with the mobile device through Bluetooth or NFC to generate and transmit the first connection information; transport layer encryption: using advanced encryption standards such as AES-256 to ensure data security during communication; identity authentication: using digital certificates and key exchange protocols to ensure that only authorized devices can connect and communicate. The storage module uses a high-performance database (such as MySQL, PostgreSQL, MongoDB) to store and manage user fingerprint information, facial information, and mobile device information; fingerprint information, facial information, and mobile device information are bound together through user ID to form a multi-authentication record; all stored data is encrypted with AES-256, and strict access control ensures that only authorized personnel and system components can access and operate sensitive data.

[0086] In any of the above embodiments, the first communication unit and the second communication unit are separated by a door body so as to increase the perception difference between the first communication unit and the second communication unit when people are around the door body, and the first communication unit is also used to obtain the second connection information between the mobile device and the network device.

[0087] The control module generates a prompt message played by the broadcast module according to the first connection information and the second connection information. When the first connection information and the second connection information both include the connection status and connection strength of the mobile device, the difference between the first connection information and the second connection information enables the system to distinguish whether the person carries the mobile device when leaving the room, and plays the prompt message if the person does not carry the mobile device.

[0088] In this embodiment, the intelligent sensing door control system intelligently determines whether a person carries a mobile device when leaving the room by comparing the first connection information and the second connection information. The specific steps are as follows: When the mobile device carried by the person enters the sensing range of the second communication unit, the second communication unit scans and identifies the device and generates the first connection information (including device ID, signal strength, and connection status); at the same time, the first communication unit obtains the connection status and signal strength of the device in the indoor network and generates the second connection information; the control module compares the first connection information (outdoor device connection status) and the second connection information (indoor device connection status). If the second connection information shows that the device is still connected to the indoor network, and the first connection information shows that the device connection status is weak or disconnected, the system determines that the person is about to leave and is carrying a mobile device; by analyzing the trend of signal strength changes, the control module further confirms the direction of movement of the device. For example, the gradual weakening of the signal strength indicates that the person is leaving; based on the above judgment, the control module can start the image sensor and display module in advance before the person completely enters the sensing range of the sensor module, and prepare for rapid facial or fingerprint recognition. This mechanism significantly shortens the response time of identity authentication and improves the efficiency of the system and user experience.

[0089] When the system determines that a person leaves the room with a mobile device, the broadcast module plays a specific prompt tone, such as "Please take your mobile device with you", to remind the user to confirm the carrying status of the device; if the system detects that the person leaves without a mobile device, the broadcast module plays a different prompt tone, such as "Mobile device not detected", to remind the user that the device may have been forgotten. After successfully identifying and confirming whether the person is carrying a mobile device, the broadcast module plays a confirmation tone to inform the user that the system has completed the detection. When the system finds an abnormality during the detection process (such as mismatched device information, abnormal signal, etc.), the broadcast module will sound an alarm to prompt the user to reconfirm or contact the administrator.

[0090] Through the collaborative work of the first communication unit and the second communication unit, the intelligent induction door control system realizes an efficient environmental data acquisition and personnel identification mechanism. In particular, in terms of detecting whether a person carries a mobile device, the system can intelligently judge and promptly remind the user by analyzing the difference in connection information. This function not only improves the security and intelligence level of the system, but also greatly optimizes the user experience and the energy efficiency management of the system; the long-distance perception capability of the second communication unit enables the system to pre-start the sensor module before the person is completely close to the access control system, shorten the response time of identity authentication, and improve the efficiency of access; by analyzing the connection information, the control module can optimize the startup and shutdown timing of each module, reduce unnecessary energy consumption, and extend the battery life of the system; the real-time sound prompts provided by the broadcast module enable users to understand the working status of the system in a timely manner, reduce confusion and uncertainty during operation, and improve overall user satisfaction; multi-level identity authentication and real-time monitoring mechanisms ensure that only authorized personnel can pass through the access control system to prevent unauthorized personnel from illegally entering; by intelligently detecting whether a person carries a mobile device, the system can promptly remind the user to prevent the forgetting or loss of important equipment, and improve the user's sense of security and convenience.

[0091] Furthermore, the connection information definition includes:

[0092] First connection information (generated by the outdoor communication unit): Device ID: uniquely identifies the person's smartphone, such as Device_12345; Connection status: Connected or Disconnected; Connection strength: percentage of signal strength (0%-100%)

[0093] Second connection information (obtained by the indoor communication unit): Device ID: uniquely identifies the person's smartphone, such as Device_12345; Connection status: Connected or Disconnected; Connection strength: percentage of signal strength (0%-100%).

[0094] Connection status comparison:

[0095] Scenario A: The second connection information shows that the device is connecting, and the first connection information shows that the device is connecting.

[0096] Scenario B: The second connection information shows that the device is connected, and the first connection information shows that the device is not connected.

[0097] Scenario C: The second connection information shows that the device is not connected, and the first connection information shows that the device is not connected.

[0098] Connection strength comparison:

[0099] Scenario A includes: second connection information, the connection state is Connected, and the connection strength is 90%; first connection information, the connection state is Connected, and the connection strength is 80%.

[0100] Scenario B includes: second connection information, the connection state is Connected, and the connection strength is 90%; first connection information, the connection state is Disconnected, and the connection strength is 0%.

[0101] Scenario C includes: second connection information, the connection state is Disconnected, and the connection strength is 0%; first connection information, the connection state is Disconnected, and the connection strength is 0%.

[0102] Scenario 1: A person is about to leave the room and is carrying a mobile device (Scenario A)

[0103] The second connection information shows that the person's smartphone is still connected to the indoor network, and the connection strength is 90%. The first connection information shows that the connection status of the person's smartphone in the outdoor communication unit is Connected, and the connection strength is 80%.

[0104] The judgment logic includes: since both the first connection information and the second connection information show that the device is in a connected state and the connection strength is reduced, the system judges that the person's mobile phone is moving from indoors to outdoors, but is still carried with him.

[0105] System response: No prompt message is played because the device is still being carried; the sensor module maintains high sensitivity to ensure that identity verification is completed quickly and accurately.

[0106] Scenario 2: The person is about to leave the room and does not carry a mobile device (Scenario B)

[0107] The second connection information shows that the connection status of the person's smartphone is Connected, and the connection strength is 90%. The first connection information shows that the connection status of the person's smartphone on the outdoor communication unit is Disconnected, and the connection strength is 0%.

[0108] The judgment logic includes: the second connection information shows that the device is still connected to the indoor network, while the first connection information shows that the device is not connected, indicating that the person's mobile phone is no longer within the range of his or her carrying range.

[0109] System response: Play the prompt message: "Please bring your mobile device" to remind people to check whether the mobile phone is left indoors; reduce the sensitivity of the sensor module to save energy.

[0110] Scenario 3: The person has completely left the room and has no mobile device with him (Scenario C)

[0111] The second connection information shows that the connection status of the person's smartphone is Disconnected, and the connection strength is 0%. The first connection information shows that the connection status of the person's smartphone on the outdoor communication unit is Disconnected, and the connection strength is 0%.

[0112] The judgment logic includes: the second connection information and the first connection information both show that the device is not connected, confirming that the person does not carry his mobile phone with him.

[0113] System response: Play the prompt message: "Please bring your mobile device" to further confirm whether the device is left behind; turn off the sensor module and enter low power mode to extend the system battery life.

[0114] In any of the above embodiments, the display module is also used to display the current open and closed state of the door body; when the sensor module is activated by the first connection information, the control module adjusts the display brightness of the display module.

[0115] In this embodiment, the display module monitors the opening and closing status of the door in real time and provides feedback to the user through intuitive graphics or text information. For example, when the door is in a closed state, the display module displays "Door is closed", and when the door is in an open state, the display module displays "Door is open". This status feedback enables the user to clearly understand the actual working status of the door, avoiding misoperation or safety hazards caused by unclear door status.

[0116] During operation, the display module adjusts its display brightness according to the brightness of the current environment. This function is controlled by the control module according to the environmental data obtained from the first connection information. Specifically, when the sensor module is started through the first connection information, the control module dynamically adjusts the brightness of the display module according to the signal strength and the ambient light conditions. The implementation of this function can optimize the readability of the display module in different environments and improve the energy saving of the system.

[0117] For example, in a strong light environment, the brightness of the display module will automatically increase to ensure that the displayed information is clearly visible; in a low light environment, the brightness will be reduced to reduce unnecessary energy consumption and maintain a comfortable visual effect. When the sensor module is started, the control module analyzes the brightness of the current environment based on the first connection information received. According to the ambient light intensity, the control module adjusts the brightness setting of the display module. If the environment is dark, the system will increase the brightness to ensure clear display of information; in daytime or strong light environment, the brightness will be appropriately reduced to achieve a balance between optimizing visual effects and reducing energy consumption.

[0118] In any of the above embodiments, the adjustment of display brightness includes the following situations:

[0119] In the first scenario, when the control module receives the first connection information but does not receive the second connection information, it means that a person may need to enter the room from the outside. In this scenario, person identification is required. The control module adjusts the display brightness of the display module to the maximum value to assist the sensor module in identifying people with the maximum range and maximum perception.

[0120] In the second scenario, when the control module receives the first connection information and the second connection information at the same time, it means that the person moves from indoors to outdoors. The control module adjusts the display brightness of the display module according to the environmental data to reduce the system power consumption while ensuring that the person can read it.

[0121] In this embodiment, the display module is not only responsible for displaying the door opening and closing status and identity authentication information, but also undertakes the key function of dynamically adjusting the display brightness. This function is intelligently adjusted by the control module according to different connection information situations to optimize the system's recognition efficiency and energy consumption management. The following describes in detail the two main situations of display brightness adjustment:

[0122] Description of Scenario 1: When the control module receives the first connection information (generated by the second communication unit, reflecting the connection status and signal strength of the mobile device outdoors), but does not receive the second connection information (obtained by the first communication unit, reflecting the connection status and signal strength of the mobile device in the indoor network), the system determines that a person may enter the room from the outdoors. In this case, in order to ensure that the system can accurately and quickly identify the identity of the person, the display module needs to adjust the brightness to the maximum value to assist the sensor module in efficient personnel identification. The control module first analyzes the received first connection information and confirms that a mobile device is approaching the access control system. Since the second connection information is not received, the system determines that the mobile device has not yet connected to the indoor network, indicating that the person is approaching from the outdoors to the indoors. The control module sends a command to the display module to adjust the display brightness to the maximum value. This adjustment ensures that the display information is still clearly visible in complex lighting or low-light environments, assisting users in obtaining accurate visual feedback during the identification process. The maximum brightness setting also optimizes the working environment of the image sensor, improving its recognition accuracy and range under different lighting conditions. With the help of high brightness, the image sensor can more effectively capture the facial information and other biometric features of people, especially in low light or low contrast conditions, the system's recognition ability is significantly enhanced. This pre-brightness adjustment reduces the false recognition rate of identity verification and ensures that only authorized personnel can pass through the access control system smoothly.

[0123] Description of situation 1: When the control module receives the first connection information and the second connection information at the same time, it indicates that the current person is moving from indoors to outdoors. In this case, the system needs to intelligently adjust the brightness of the display module according to the environmental data to ensure that the displayed information is readable while reducing the energy consumption of the system. The control module compares the first connection information (outdoor connection status and signal strength) with the second connection information (indoor connection status and signal strength). By analyzing the difference between the two, the system determines that the person is leaving the indoor area and confirms whether the person is carrying a mobile device. The control module uses the environmental data (such as light intensity, temperature, etc.) obtained by the first communication unit to evaluate the lighting conditions of the current environment. Based on the environmental data, the control module dynamically adjusts the brightness of the display module. For example: in a bright outdoor environment, the system may not need to maintain high brightness, but can appropriately reduce the display brightness to reduce battery consumption and avoid user visual fatigue; if the person is in low light conditions when leaving, the control module will appropriately increase the display brightness to ensure the readability of the displayed information and prevent the information from being blurred due to insufficient light. The control module uses an intelligent algorithm to minimize the energy consumption of the display module while ensuring that the displayed content is clearly visible. This adjustment not only extends the battery life of the system, but also reduces unnecessary energy waste and improves the overall energy efficiency of the system. Through precise brightness control, the system can adapt to changing external environmental conditions and maintain the reliability of information display and the visual comfort of users.

[0124] The embodiment of the second aspect of the present invention provides a control method. In some embodiments of the present invention, such as Figure 2 As shown, the control method includes the following steps:

[0125] S101, obtaining environmental data of the environment where the sensor module is located in real time through the communication module.

[0126] S102, adjusting the sensing range and / or sensitivity of the sensor module when it is turned on according to the environmental data.

[0127] S103, when sensing the presence of a person on the outdoor side of the door body, the control module activates the sensor module to obtain the identification information of the person and matches it with the pre-stored identification information.

[0128] S104, generating alarm information and / or control data according to the matching result.

[0129] The present invention provides a control method, in step S101, the communication module is responsible for real-time collection of various data of the environment where the sensor module is located, including light intensity, temperature, humidity, noise level, etc. These environmental data provide comprehensive background information for the system, so that subsequent control decisions can be more accurate and intelligent. According to step S102, the system dynamically adjusts the sensing range and sensitivity of the sensor module using the collected environmental data. For example, during the day when the light is sufficient, the sensor module can appropriately reduce the sensitivity to reduce false triggering; while at night when the light is dim, the sensitivity is increased to ensure that the presence of people can be accurately identified. In addition, environmental data can also be used to adjust the sensing range to adapt to different personnel flow densities and activity patterns, thereby optimizing the response speed and accuracy of the system. In step S103, when the sensor module detects that a person appears outside the door body, the control module immediately starts the sensor module to obtain the person identification information. This process includes the application of multiple biometric identification technologies such as fingerprint recognition and facial recognition. The obtained person identification information will be quickly matched with the authorization information pre-stored in the system to confirm the identity and authority of the person. This step ensures that only authorized personnel can enter a specific area, greatly improving the security of the system. In step S104, the system determines the next operation based on the matching result. If the recognition is successful, the system will generate corresponding control data to instruct the door to unlock and allow the person to enter. At the same time, the system will record the detailed information of the visit for subsequent audit and management. If the recognition fails, the system will generate an alarm message to notify the relevant personnel to take necessary security measures, such as sounding an alarm, locking the access control system, or notifying security personnel. This mechanism not only prevents unauthorized access, but also provides immediate security feedback, ensuring the high reliability of the system.

[0130] In summary, the operating efficiency, security and user experience of the intelligent induction door control system are optimized. Real-time acquisition of environmental data and dynamic adjustment of the sensing range and sensitivity of the sensor module ensure that the system can efficiently and accurately identify personnel under different environmental conditions. At the same time, through multiple identity authentication and instant alarm mechanism, the security protection capability of the system is greatly improved. Intelligent energy consumption management and flexible system adjustment not only extend the service life of the equipment, but also reduce operation and maintenance costs. Overall, this control method provides an efficient, safe and intelligent solution for the intelligent induction door control system, which meets the strict requirements of modern intelligent buildings and high-security places for access control systems.
