IoT Gas Stove Unified Architecture: System Design
The IoT Gas Stove Unified Architecture integrates three core layers—Perception, Network, and Application—to ensure safety and enable remote control. This system uses sensors for real-time monitoring of gas leaks, flames, and temperature, processes data via a microcontroller, and provides user interaction through safety protocols and remote management interfaces, significantly enhancing kitchen safety and efficiency.
Key Takeaways
The Perception Layer uses sensors like MQ-6 and Flame sensors for critical safety data input.
Actuators, such as the Solenoid Valve, enable immediate physical control over gas flow.
The Network Layer, centered on the MCU and WiFi, handles data processing and connectivity.
Safety protocols include automatic shutoff on flame loss and immediate gas leak alarm triggers.
Remote management allows users to monitor status and control the stove via a WiFi interface.
What components make up the Perception Layer in an IoT Gas Stove?
The Perception Layer serves as the physical interface, gathering environmental data and executing immediate physical responses. It utilizes various sensors to monitor critical parameters like gas presence (MQ-6), combustion status (Flame Sensor), and overheating (Temperature Sensor). Simultaneously, actuators like the Solenoid Valve and Relay Module translate digital commands into physical actions, such as cutting off the gas supply or switching power, ensuring rapid response to detected hazards. This layer is crucial for real-time safety monitoring and direct interaction with the physical environment of the stove.
- MQ-6 Sensor (Gas Leak): Detects combustible gases like LPG and natural gas, providing crucial input for immediate leak alarms and safety shutdowns.
- Flame Sensor (Combustion Check): Confirms the presence or absence of a flame, enabling the system to detect accidental flame loss and trigger automatic gas shutoff.
- Temperature Sensor (Overheat): Monitors the stove surface or surrounding environment temperature to prevent overheating and potential fire hazards.
- Load Sensor (Pot Weight): Measures the weight placed on the burner grate, allowing the system to determine if a pot is present and if cooking is actively occurring.
- Solenoid Valve (Gas Control): An electromechanical actuator that physically opens or closes the gas line, providing precise and rapid control over the fuel supply.
- Relay Module (Power Switching): Used to safely switch high-power components, such as the ignition system or main power supply, based on microcontroller commands.
- Buzzer & LED Indicator (Immediate Alerts): Provides local, non-networked feedback to the user through audible alarms and visual status lights for immediate hazard notification.
- LCD Display (Local Readout): Offers a clear, local interface for displaying real-time status, temperature readings, and error messages directly on the stove unit.
How does the Network Layer manage data and connectivity in the IoT Gas Stove?
The Network Layer functions as the system's intelligence center, responsible for processing sensor data, interpreting commands, and enabling external communication. The Microcontroller (MCU) is central, performing sensor data processing and fusion to make informed decisions based on multiple inputs. A dedicated WiFi Module facilitates connectivity, allowing the stove to transmit status updates to the cloud and receive remote commands from the user interface. This layer ensures that the stove can operate autonomously while remaining accessible for remote monitoring and necessary firmware updates, bridging the gap between physical sensing and user application.
- Sensor Data Processing & Fusion: The MCU aggregates and analyzes input from multiple sensors to make complex safety decisions, filtering noise and ensuring data reliability.
- Command Interpretation: Processes instructions received from the Application Layer or local controls, translating user intent into specific actions for the actuators.
- Remote Monitoring Interface: Allows users to view the stove's operational status, sensor readings, and safety alerts from a distance via a connected mobile application or web portal.
- Firmware Updates: Enables over-the-air (OTA) updates to the microcontroller, ensuring the system benefits from security patches and new features without physical intervention.
What user interactions and safety features are handled by the Application Layer?
The Application Layer defines the user-facing functionality, focusing primarily on safety protocols and remote management capabilities. Safety is paramount, implemented through automated responses like auto shutoff upon flame loss and immediate alarm triggers upon detecting a gas leak, ensuring immediate hazard mitigation. Furthermore, the layer leverages the network connectivity to offer remote management, allowing users to check the stove's status or initiate remote ON/OFF control via a connected interface. This layer translates raw data into actionable safety and convenience features for the user, providing peace of mind and control.
- Auto Shutoff on Flame Loss: A critical safety feature that automatically closes the Solenoid Valve if the Flame Sensor indicates combustion has ceased unexpectedly.
- Gas Leak Alarm Trigger: Immediately activates the local Buzzer and sends a remote notification when the MQ-6 sensor detects gas concentrations above a safe threshold.
- Remote ON/OFF Control: Provides the ability to safely turn the gas supply on or off remotely, offering convenience and an emergency shutoff option from anywhere.
- Status Reporting: Continuously transmits operational data, including temperature, gas levels, and current activity, to the user's remote interface for comprehensive oversight.
