Technical Field

[0001] The present invention relates to the field of gas safety technology, and in particular to an intelligent gas safety valve and an intelligent method for opening and closing the safety valve. Background Art

[0002] As an important energy source, gas is widely used in households, businesses and industries. However, due to the flammable and explosive nature of gas, there are potential safety risks in the use of gas, especially in the case of gas leakage, equipment failure or operational errors, which may cause serious fire or explosion accidents. Therefore, ensuring the safety of gas use is a core issue in the design of gas equipment and systems.

[0003] Traditional gas safety valves usually rely on mechanical control or simple electric control. Although these methods can prevent gas leaks to a certain extent, they have many limitations. First, traditional gas valves lack intelligent monitoring methods and cannot monitor the operating status of the gas system in real time. Therefore, in the event of gas leaks or other abnormal conditions, the response speed is slow and effective measures cannot be taken in time. Secondly, most traditional gas safety valves require manual operation, which not only increases the complexity of use, but also poses the risk of human error. In addition, the remote control function of traditional valves is limited, and users cannot monitor and manage gas equipment remotely, which cannot meet the requirements of modern smart homes or industrial automation. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 This is a system architecture diagram of an intelligent gas safety valve of the present invention; Figure 2 This is a flow chart of a method for intelligently opening and closing a safety valve of an intelligent gas safety valve of the present invention. DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please see attached Figure 1 - Attachment Figure 2 The embodiment of the present invention provides an intelligent gas safety valve, including: Sensor unit: Installation of sensor units: sensor units are usually installed at key nodes of gas pipelines or near gas equipment to ensure real-time monitoring of gas operating parameters. By properly arranging sensor locations, key parts of the gas system can be covered to the maximum extent, ensuring that every possible leak or abnormality can be monitored in a timely manner.

[0022] Gas sensor: Gas sensors use semiconductor technology and have the characteristics of high sensitivity and high stability. They can detect extremely small amounts of combustible gases (such as methane, ethane, propane, etc.). In addition, the sensor surface is covered with special catalytic materials that can accelerate the reaction speed between the gas and the sensor, thereby achieving rapid response. For industrial applications, gas sensors can also use infrared absorption technology to achieve high-precision gas concentration measurement by detecting the absorption spectrum of specific gases.

[0023] Pressure sensor: Pressure sensors usually use resistance strain gauge technology to determine whether there is an abnormality by monitoring the pressure changes in the pipeline. For example, in a gas pipeline, if the pressure drops suddenly, it may mean that there is a leak in the pipeline; if the pressure is too high, it may mean that the pipeline is blocked or the gas equipment is faulty. Pressure sensors can detect tiny pressure changes through high-precision measuring elements and respond quickly to pressure abnormalities through the control unit.

[0024] Temperature sensor: The temperature sensor uses thermocouple technology to monitor the temperature of gas equipment in real time and issue an alarm when the temperature exceeds the preset range. Thermocouple sensors have a wide temperature measurement range and can still maintain good linear output under high temperature conditions. They are suitable for temperature monitoring of various gas equipment. For different application scenarios, temperature sensors can choose suitable materials and structures to meet specific measurement requirements.

[0025] Flow Sensors: Flow sensors use turbine flowmeter or ultrasonic flowmeter technology to accurately measure the flow of gas through the pipeline. Flow sensors can identify abnormal gas consumption patterns, such as gas flow when no one is using it, indicating a possible leak or equipment failure. By combining the flow sensor data with other sensors, the system can further improve overall safety.

[0026] Control unit: Hardware structure of the control unit: The control unit is the core of the entire intelligent gas safety valve, and uses an embedded microcontroller (such as the ARMCortex-M series) to implement various functions of the system. The control unit includes multiple modules, such as data acquisition module, data processing module, logic control module and self-diagnosis module. The data acquisition module is responsible for receiving real-time data from the sensor unit and passing this data to the data processing module.

[0027] Decision logic module: The decision logic module analyzes and processes data according to preset safety thresholds and logic algorithms. The logic algorithm can be customized according to the needs of different application scenarios. For example, home users may be more concerned about the rapid response to gas leaks, while industrial users need to comprehensively consider the changing trends of pressure, temperature and flow. The design of the decision logic module is based on a multi-level safety mechanism. Once an abnormal situation is detected, the system will respond in the shortest possible time and issue a command to close the valve.

[0028] Self-diagnosis function module: The self-diagnosis function module can periodically detect the status of each component inside the control unit and the connected sensors and actuators. The module can promptly detect problems such as sensor failure, valve stagnation or communication failure, and send fault alarm information through the communication unit to remind users to perform maintenance and repairs. This design greatly improves the reliability of the system and reduces safety hazards caused by equipment failure.

[0029] Data storage and analysis module: The control unit also includes a data storage and analysis module for storing historical operating data of the gas system. By analyzing historical data, the system can identify potential risk trends, such as frequent gas concentration increases or pressure fluctuations in a certain period of time. By introducing machine learning algorithms, the system can continuously optimize its control strategy and improve its responsiveness to complex situations.

[0030] Execution Unit: The structure of the actuator unit: The actuator unit is mainly responsible for the opening and closing operation of the valve to ensure that the gas supply can be quickly cut off in an emergency. The actuator unit includes electric valves, solenoid valves and pneumatic valves. Each valve type has unique advantages and is suitable for different application scenarios.

[0031] Application of electric valves: Electric valves are driven by DC motors and achieve smooth opening and closing of valves through precise motor control. Electric valves have high control accuracy and are suitable for occasions where gas flow needs to be frequently adjusted, such as laboratory equipment or high-precision gas equipment. In the design, electric valves are usually equipped with limit switches and position sensors to ensure that the valve is always in the expected open and closed state.

[0032] Application of solenoid valve: Solenoid valve relies on the magnetic force generated by the electromagnetic coil to drive the valve core to move, thereby realizing the rapid cut-off of gas. Solenoid valve has a fast response speed and is particularly suitable for occasions where the gas supply needs to be cut off urgently, such as emergency treatment after a gas leak alarm. Solenoid valve has a simple structure and a small size, and is easy to integrate into compact gas equipment.

[0033] Application of pneumatic valves: Pneumatic valves are driven by compressed air and are suitable for use in industrial environments that require explosion-proof or remote control. The advantages of pneumatic valves are their wide adaptability to working environments, as well as their high durability and safety. By combining pneumatic valves with solenoid valves, complex safety control logic can be achieved to meet the needs of various industrial applications.

[0034] Communication unit: Connection method of communication unit: The communication unit exchanges data with external devices or systems through a variety of communication protocols, such as Wi-Fi, Zigbee, LoRa and NB-IoT. These communication protocols have different advantages. Wi-Fi is suitable for short-distance high-speed communication in home and office environments, Zigbee is suitable for low-power smart home devices, and LoRa and NB-IoT are designed for long-distance and low-power IoT applications.

[0035] Remote control and management: Users can monitor the status of the gas system in real time through mobile applications or web platforms. The communication unit transmits the data of the gas safety valve to the cloud server, and users can access and control the system at any time. For example, when the user is not at home but wants to check whether the gas equipment is turned off, he can send a command to close the valve through the mobile application to ensure gas safety.

[0036] Alarms and notifications: The communication unit is also responsible for sending system status and alarm information to users in a timely manner. When an abnormal situation is detected, such as excessive gas concentration or abnormal pressure, the communication unit will immediately alert the user through SMS, email or push notification, and provide corresponding recommended measures.

[0037] Backup power supply: Design of backup power supply: In order to ensure that the intelligent gas safety valve can still operate normally when the main power fails or the power is cut off, the present invention is equipped with a high-capacity lithium battery and a super capacitor. The lithium battery is responsible for providing long-term emergency power for the system, while the super capacitor is used to provide instantaneous high power output when the power demand suddenly increases to ensure the rapid closure of the valve.

[0038] Power management: The system integrates an intelligent power management module, which can automatically switch the power source according to the status of the main power supply and the backup power supply. After the main power supply is restored to normal power supply, the power management module will automatically charge the lithium battery to ensure that the backup power supply is always fully charged. In addition, the power management module can also monitor the health status of the battery to prevent over-discharge or over-charge of the battery, thereby extending the battery life.

[0039] A method for intelligently opening and closing a safety valve of an intelligent gas safety valve comprises the following steps: S1: Real-time monitoring: Multi-parameter monitoring: The system uses sensor units to monitor various operating parameters of the gas in real time, including gas concentration, pressure, temperature and flow. The data of each sensor is collected in real time and transmitted to the control unit to form a comprehensive gas safety monitoring system. Through this multi-parameter monitoring, the system can accurately grasp the status of the gas system at any time, and promptly discover and deal with possible safety hazards.

[0040] Data synchronization and transmission: In order to ensure the real-time nature of data, the system uses high-speed data bus or wireless data transmission technology to synchronously transmit the data of the sensor unit to the control unit. This design not only improves the efficiency of data transmission, but also reduces the risk of data loss.

[0041] S2: Data analysis and processing: Data processing logic: The control unit receives and processes real-time data from the sensor unit and analyzes it through preset safety thresholds and logic algorithms. If any abnormality is detected, the control unit will immediately trigger the corresponding emergency measures. To ensure the response speed of the system, the control unit integrates a high-performance processor and a dedicated algorithm chip, which can complete data processing and decision-making within milliseconds.

[0042] Abnormal detection and feedback: When analyzing data, the control unit not only considers the current measurement value, but also combines historical data for trend analysis. For example, if the system detects that the gas concentration continues to increase over a period of time, even if it does not reach the alarm threshold, the control unit will issue an early warning to prompt the user to check the status of the gas equipment. Through this intelligent abnormal detection and feedback mechanism, the system can provide early warning before danger occurs.

[0043] S3: Detect abnormality and close the valve: Abnormal situation handling: When the control unit detects that any parameter exceeds the safety threshold (such as gas concentration exceeds the preset upper limit, pressure drops suddenly, etc.), the system will immediately issue a command to close the gas valve in the execution unit. After receiving the command, the execution unit will respond quickly and cut off the gas supply to prevent the potential danger from further expanding.

[0044] Alarm transmission and remote notification: At the same time, the communication unit will immediately send an alarm message to the user through the preset communication channel (such as SMS, email, application notification). The alarm message not only includes the current abnormal situation, but also may include the system's recommended treatment measures, such as contacting the gas company or urgently evacuating on-site personnel.

[0045] S4: Remote monitoring and control: User monitoring and control: Under normal operating conditions, users can monitor the status of the gas safety valve in real time through mobile applications, web platforms or other external devices. The communication unit will regularly upload the system's operating data (including current gas concentration, pressure, temperature, valve status, etc.) to the cloud server, and users can access this data at any time through mobile devices to understand the latest status of the gas system.

[0046] Remote operation: Users can remotely control the opening and closing of gas valves at any time. For example, if a user finds that the gas valve at home is not closed during a business trip, he can remotely close the valve through the mobile phone application to ensure the safety of the family. In addition, users can also set safety thresholds and alarm notification preferences through the application to adapt to different usage needs.

[0047] S5: Timing control: Timed opening and closing function: The system is equipped with a timing control unit, through which users can set the opening and closing schedule of the gas valve. For example, users can set the system to automatically close the gas valve at night and automatically open it in the morning to avoid the risk of gas leakage at night. At the same time, during holidays or when away for a long time, users can also pre-set the valve closing time to ensure that the gas equipment is in the closed state when no one is using it, thereby reducing unnecessary energy consumption.

[0048] Multi-scenario control: Users can set opening and closing plans for multiple time periods according to different application scenarios. For example, in industrial applications, users can set corresponding valve opening and closing times for different work shifts to ensure smooth switching of the gas system between shifts. In commercial places, users can set automatic start and stop of gas equipment according to business hours to further improve the operational efficiency of the system.

[0049] S6: Self-diagnosis and maintenance reminder: Periodic self-diagnosis: The system regularly checks the working status of sensors and actuators through the self-diagnosis function module to automatically detect system failures. For example, the system regularly tests the sensitivity of sensors, checks the opening and closing speed of valves, and verifies the connection stability of communication units. If any abnormality is found, the system will immediately issue a maintenance reminder and recommend the user to make necessary repairs or replacements.

[0050] Fault recording and analysis: After each self-diagnosis, the system will record the test results and analyze the fault conditions. For example, if a sensor has a high frequency of failure, the system will mark it as a key focus and give it priority in the next self-diagnosis. Through this continuous fault recording and analysis, users can keep abreast of the health status of the equipment and avoid potential safety hazards.

[0051] Historical data analysis and prevention: Intelligent analysis and optimization: The system not only analyzes the current operating data, but also conducts in-depth trend analysis based on historical data. For example, by analyzing the data of the past few months, the system can find the changing trends of gas consumption and optimize the control strategy based on these trends, such as adjusting the safety threshold or optimizing the timing opening and closing plan.

[0052] Machine learning application: In step S3, the control unit can further analyze historical data and predict possible future failures or dangers by introducing machine learning algorithms. For example, by analyzing a large amount of historical data, the machine learning algorithm can identify some potential dangerous patterns, such as abnormal fluctuations in gas concentration under certain conditions, and take preventive measures in advance to reduce the probability of failure.

[0053] Multiple scene settings: Flexible scenario management: In step S5, users can set gas valve opening and closing plans for multiple time periods according to different usage scenarios. For example, in home applications, users can set valve opening times in the morning and evening, and close valves during unoccupied periods to prevent accidental leaks. In industrial applications, users can set gas valves to be closed during equipment maintenance to ensure safe operation.

[0054] Scene switching and optimization: Users can also switch or adjust the set scene plan at any time as needed. For example, during holidays, users can temporarily turn off the automatic start function of all gas equipment to avoid unnecessary energy consumption. After the holidays, users can restore the previous settings to ensure that the system runs normally as planned.
