Description

Technical Field

[0001] This invention relates to the field of intelligent control technology, and in particular to an intelligent linkage control system for multiple devices in a small enclosed cabin. Background Technology

[0002] With the development of the sharing economy and educational technology, small, enclosed study pods, psychological counseling pods, and shared office pods are becoming increasingly popular in public places. These pods typically integrate various environmental control devices such as air conditioning, fresh air systems, dimmable lighting, electrically controlled privacy glass, and audio playback, aiming to provide users with an independent, comfortable, and private space.

[0003] However, existing cabin environment control technologies have the following drawbacks: First, control is decentralized and cumbersome to operate. Users must manually adjust each switch or remote control after entering, affecting the immersive experience. Second, there is a lack of intelligent linkage. For example, the activation of the fresh air system may cause a sudden change in cabin temperature, but the air conditioning system does not actively compensate for the temperature change. Third, privacy protection is passive, mostly relying on fixed physical frosted films or manual curtains, which cannot automatically switch to privacy mode after the user is seated. Fourth, scene switching is rigid and energy consumption is high. It cannot automatically switch between learning, relaxation, and energy-saving modes according to a schedule, and high-power equipment may still run at full power when no one is present, resulting in energy waste.

[0004] Therefore, there is an urgent need for an intelligent linkage control system that can deeply integrate sensor perception, user identification, and multi-device collaborative logic. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a small enclosed cabin multi-device intelligent linkage control system and method to solve the technical problems of decentralized equipment control, lack of intelligent collaboration, passive privacy protection and rigid scene switching in the existing cabin environment, so as to realize the full automation, self-adaptation and multi-scene intelligent adjustment of the cabin environment.

[0006] Technical solution: A small enclosed cabin multi-device intelligent linkage control system, comprising: The main controller has a built-in timing module and scene linkage strategy engine; The identity awareness module is used to verify the user's identity; The personnel status detection module is used to detect the seated status of personnel inside the cabin; An environmental sensing module, including at least a temperature sensor and a carbon dioxide concentration sensor; The execution equipment includes at least an air conditioner, a fresh air fan, an electronically controlled dimming glass door and its drive module; A communication interface connects the identity perception module, personnel status detection module, environmental sensing module, and execution device to the main controller; The main controller is configured as follows: In response to successful identity verification and detection of people sitting down, the electronically controlled dimming glass door is switched to a privacy state. The air conditioner's operating mode is adaptively controlled based on temperature and the presence of people. According to the preset schedule of the timing module, the scene linkage strategy engine is triggered to switch the working scene of the cabin; When the carbon dioxide concentration exceeds the standard, the fresh air fan should be started first and the air conditioner should be coordinated to compensate for the temperature.

[0007] Preferably, the electrically controlled dimming glass door is made of electrochromic (EC) glass, the drive module supports 0-10V analog voltage control, and the main controller realizes continuous stepless adjustment of the glass transmittance within the range of 5%-85% by outputting voltage signals, with a response time of no more than 2 seconds.

[0008] Preferably, the system further includes an external light sensor; when the electrically controlled dimming glass door is in transparent mode and the external light intensity exceeds a preset glare threshold, the main controller automatically sends a low light transmittance adjustment command to the drive module to adjust the glass transparency to 20%-50%.

[0009] Preferably, the personnel status detection module includes a millimeter-wave radar sensor or an active infrared sensor, via I... 2 The C-bus or UART serial port connects to the main controller to detect the micro-movements and breathing status of the personnel inside the cabin.

[0011] Preferably, the preset timetable of the timing module supports local and remote configuration, and the main controller reserves an HTTP API interface for connecting to the academic affairs system or management backend to dynamically retrieve timetable information and automatically generate the trigger time for the break relaxation mode.

[0012] Preferably, the main controller is further configured to: in sleep mode, control the LED lighting fixtures to linearly and gradually decrease to 0 within 30 seconds, reduce the air conditioner fan speed to the minimum to maintain basic ventilation, switch the electronically controlled dimming glass door to a transparent state or maintain the state last set by the user, and power off unnecessary modules, while generating a daily usage log and uploading it to the backend server.

[0013] This invention also provides a method for intelligent linkage control of multiple devices in a small enclosed cabin, based on the above system, comprising the following steps: S1. Identity verification and seating detection: The user's identity is verified through the face recognition module. After receiving the recognition success signal, the sensor monitoring the presence of a human body in the cabin will detect when a person sits down. The main controller will control the electronically controlled dimming glass door to switch to an opaque state. S2, Temperature-Human Body Dual Criterion Adaptive Regulation: Real-time acquisition of cabin temperature T, combined with personnel status detection results to execute air conditioning control strategy; S3, Multi-scenario autonomous switching driven by timed strategy: The main controller has a built-in timed module that automatically switches the cabin working scenarios according to a preset schedule, including standby mode, relaxation mode, and hibernation mode, and adjusts the status of lights, air conditioning, fresh air, electric glass and audio equipment in each scenario respectively. S4. Device Coordination Conflict Resolution: The scene linkage strategy engine handles multi-device control conflicts according to preset priorities, including prioritizing the response to carbon dioxide concentration exceeding the standard signal to force the start of fresh air, monitoring temperature fluctuations and dynamically compensating for air conditioning outlet temperature during forced ventilation, and ensuring synchronized sound and light actions.

[0014] Beneficial Effects: Compared with the prior art, the present invention has the following beneficial effects: 1) It achieves a seamless intelligent experience with "zero operation," where all environmental adjustments are automatically completed by the system from the moment the user enters, sits down, to the start of activities; 2) It provides proactive and dynamic privacy protection, innovatively using identity verification and sitting behavior as signals to trigger the switching of the electrically controlled glass; 3) It achieves seamless adaptive switching across multiple scenarios, creating an all-weather intelligent companionship experience; 4) It achieves significant energy-saving and environmental protection effects, eliminating energy waste when no one is present; 5) It enhances system security and robustness, ensuring user health and comfort through priority coordination.

[0019] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1: System Hardware Architecture and Connection This embodiment provides a small enclosed cabin (approximately 1.2m long × 1.2m wide × 2.2m high) multi-device intelligent linkage control system.

[0021] The core hardware selection is as follows: Main controller: It adopts an industrial-grade microcontroller with an integrated ARM Cortex-M4 core, with a built-in RTC real-time clock module as a timing module, and has a scene linkage strategy engine program burned in.

[0022] Face recognition module: Utilizes a local edge computing binocular infrared camera module, connected to the main controller via a UART serial port, using a custom instruction set for communication. It does not rely on the cloud, protecting user privacy.

[0023] Human presence sensor: Employs a 60GHz millimeter-wave radar module, via I 2 The C-bus connects to the main controller and can accurately detect subtle movements (breathing, heartbeat).

[0024] Electrically controlled frosted glass door and drive module: The electrically controlled dimming glass door uses electrochromic (EC) glass. The drive module supports 0-10V analog voltage control. The main controller achieves continuous stepless adjustment of the glass transmittance within the range of 5%-85% by outputting voltage signals, with a response time of no more than 2 seconds.

[0025] Air conditioning: The system uses a smart air conditioner that supports the MQTT protocol. The main controller issues control commands via the MQTT protocol through the built-in Wi-Fi module.

[0026] Timing strategy configuration: The main controller supports local touch screen configuration and remote MQTT configuration, and reserves an HTTP API interface to connect to the school's academic affairs system to dynamically pull the timetable and generate the trigger time for the break relaxation mode.

[0027] Example 2: Face Recognition and Electronically Controlled Glass Privacy Linkage Control Process Once the user approaches the cabin, the facial recognition module successfully identifies them and sends a "User ID verification successful" command to the main controller. The main controller records the user's entry and begins monitoring the presence sensors. After the user sits down, the millimeter-wave radar detects a stable seating signal (5 seconds of continuous micro-motion). The main controller outputs a high-level signal to the EC glass drive module, and the glass quickly switches from transparent to fully frosted opaque. Simultaneously, if the external light sensor detects illumination >12,000 Lux and the glass is in transparent mode, the main controller outputs a 40% duty cycle PWM signal to adjust the light transmittance to approximately 50% for anti-glare.

[0028] Example 3: Case Study on Multi-Device Collaboration Conflict Resolution Initial state: 12:00 PM, user training in the cabin, temperature T=26℃, air conditioning on, CO2 concentration rises to 1480ppm. CO2 sensor reports 1520ppm, exceeding the 1500ppm safety threshold. The main controller's scenario linkage engine invokes the "safety priority" rule, forcing the fresh air fan to run at 100% speed. 20 seconds later, 30℃ hot air from outside is drawn in, and the temperature sensor measures T rising to 28.5℃ (fluctuation >2℃). According to the "temperature compensation" rule, the linkage engine immediately sends an MQTT command to the air conditioning to activate the powerful cooling mode, setting the temperature to 24℃. 2 minutes later, CO2 drops to 900ppm, the forced fresh air mode is turned off, and the air conditioning switches back to air supply. Users only perceive a brief breeze, and the perceived temperature remains constant.

[0029] Example 4: Multi-scenario switching driven by timed strategies The preset schedule is as follows: 07:00 Standby Mode: Lighting gradually brightens to 300lx, air conditioning pre-cools / preheats to 24℃, and fresh air is turned on for ventilation.

[0030] 10:05-10:15 (Dynamically adjusted according to the schedule) Relaxation mode: Lights set to 3000K warm color, 100lx low brightness, fresh air on low speed for quiet operation, and audio playback of relaxation music library.

[0031] 22:00 Sleep Mode: Lighting gradually dims over 30 seconds, air conditioner fan speed drops to minimum, electronically controlled dimming glass door switches to transparent or maintains the user's last setting, non-essential modules are powered off, and usage logs are uploaded.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
