Description

Technical Field

[0001] This invention relates to the field of gas safety control, and in particular to a normally closed intelligent electronic control valve system for preventing gas leakage. Background Technology

[0002] Gas safety has always been a significant safety hazard, especially when the manual gas valve is not shut off. If the gas supply is not cut off due to long-term use of the gas pipes, or when other quality problems occur, it can easily lead to a major safety risk.

[0003] In existing technologies, traditional gas control valves mostly employ mechanical structures, lacking intelligent monitoring and control methods, making it difficult to detect and prevent gas leaks in a timely manner. Especially in unattended locations, the lack of effective monitoring and automatic shut-off mechanisms often leads to serious safety hazards when a gas leak occurs. Furthermore, existing gas monitoring systems typically can only detect a single type of gas, unable to simultaneously handle the monitoring needs of liquefied petroleum gas (LPG) and natural gas, and lack intelligent status assessment and remote control functions.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0005] (a) Technical problems to be solved The problem to be solved by the present invention is to provide a normally closed intelligent electronic control valve system for preventing gas leakage, so as to overcome the defects of existing gas control valves, such as insufficient safety, poor user experience and poor control effect.

[0006] (II) Technical Solution To address the aforementioned technical problem, a first aspect of the present invention provides a normally closed intelligent electronic control valve system for preventing gas leakage, comprising: Gas end; The sensing module is connected to the gas end and detects whether any human is entering the surrounding area every minute. The detection module includes a first sensor and a second sensor, both of which are connected to the gas end. The first sensor is used to detect liquefied gas such as propane, and the second sensor is used to detect natural gas such as methane. An alarm module is connected to the sensing module and the detection module. When the sensing module or the detection module malfunctions, the alarm module sends out an alarm. The MCU chip provides intelligent control, data processing, and response functions for the electronic control valve. The MCU chip is connected to the sensing module, the detection module, and the alarm module. The MCU chip receives and processes data from the sensing module and the detection module. If the sensing module does not detect human entry within a set time after determining that the valve is unoccupied, the MCU chip controls the electronic control valve to close. If the detection module senses that liquefied petroleum gas (LPG) or natural gas (natural gas) such as methane exceeds the normal threshold range, the MCU chip determines that a malfunction has occurred and controls the alarm module to issue an alarm and close the electronic control valve.

[0007] As described above, in the normally closed intelligent electronic control valve system for preventing gas leakage, optionally, if the sensing module does not detect human entry within a set time, the MCU chip determines that the system is unmanned.

[0008] As described above, the normally closed intelligent electronic control valve system for preventing gas leakage may optionally include an LED light in the alarm module. When the MCU chip detects a fault, the LED light displays red; when the electronic control valve system automatically corrects itself, the LED light displays yellow; when the electronic control valve system is in normal operation, the LED light displays green; and when the electronic control valve system performs self-detection, the LED light displays a flashing green light.

[0009] As described above, the normally closed intelligent electronic control valve system for preventing gas leakage may optionally include a horn in the alarm module, which sounds an alarm when the MCU chip detects a fault.

[0010] As described above, the normally closed intelligent electronic control valve system for preventing gas leakage may optionally include a power converter for converting external power into operating power.

[0011] As described above, in the normally closed intelligent electronic control valve system for preventing gas leakage, the MCU chip is optionally connected to an external cloud platform, which is used to record the status of the MCU chip and control the electronic control valve.

[0012] As described above, in the normally closed intelligent electronic control valve system for preventing gas leakage, optionally, the MCU chip is equipped with a delay module, and the cloud platform controls the opening / closing of the delay module. When the delay function is enabled, both the sensing module and the detection module are active. When the delay function is disabled, the detection module is active and the sensing module is disabled.

[0013] As described above, the normally closed intelligent electronic control valve system for preventing gas leakage can optionally be connected to a gas pipeline, with the gas pipeline connected to the gas end.

[0014] (III) Beneficial Effects The present invention provides a normally closed intelligent electronic control valve system for preventing gas leakage, which has the following advantages: (1) This invention uses a sensing module to detect whether humans have entered the gas end. If no one enters the gas end area within one hour after it is determined to be unoccupied, the electronic control valve is closed to prevent leakage. The detection module detects liquefied petroleum gas or natural gas around the gas end. When an abnormal state is detected, an alarm is triggered by the alarm module, thereby improving safety. All data is processed, analyzed, and controlled by an MCU chip, achieving miniaturization while also providing better control.

[0015] (2) This invention incorporates a cloud platform, which can be, but is not limited to, an app or client, allowing users to remotely check and control the system's information and its on / off status. This design enhances the user experience. Attached Figure Description

[0024] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0025] In the field of gas safety control, there has long been a disconnect between leak prevention and personnel status monitoring. Traditional valve systems mostly employ a single gas detection mechanism, which cannot simultaneously address the risks of liquefied petroleum gas (LPG) and natural gas leaks. While some intelligent control solutions incorporate human body sensing capabilities, they suffer from high false alarm rates and response delays, making it difficult to promptly shut off the gas supply in unattended scenarios. A typical application scenario is a home kitchen, where users may forget to turn off the gas valve after cooking. If a minor leak occurs unnoticed at this time, it can easily lead to a safety accident.

[0026] It should be noted that the gas end refers to the interface structure that connects to the gas pipeline. The gas pipeline is used to transport gas, and electronic control valves can be installed on the gas pipeline.

[0027] See Figure 1 The present invention provides a normally closed intelligent electronic control valve system for preventing gas leakage, comprising: a gas end, a sensing module 1, a detection module 2, an alarm module 3, and an MCU chip 4.

[0028] exist Figure 1 In an optional embodiment, the sensing module 1 is connected to the gas end, and the sensing module 1 detects whether any human has entered the surrounding area every minute. The sensing module 1 can be, but is not limited to, radar, which determines the presence of a moving target by analyzing reflected waves.

[0029] It should be noted that if the sensing module 1 does not detect human entry within a set time, the MCU chip 4 determines that the device is in an unoccupied state. If the sensing module 1 does not detect human entry within a certain number of minutes after determining that the device is in an unoccupied state, the MCU chip 4 controls the electronic control valve to close. It should be noted that the specific time can be freely set by those skilled in the art according to the circumstances.

[0030] Furthermore, the detection module 2 includes a first sensor 21 and a second sensor 22, both of which are connected to the gas end. The first sensor 21 is used to detect liquefied gas such as propane, and the second sensor 22 is used to detect natural gas such as methane.

[0031] It should be noted that the MCU chip 4 has a first sensor 21 setting a threshold and a second sensor 22 setting a threshold. The data detected by the first sensor 21 and the second sensor 22 can be compared in the MCU chip 4 to determine whether a fault has occurred.

[0032] Simultaneously, the millimeter-wave radar sensor scans the monitoring area at a preset frequency. When no human movement is detected, it sends a status signal to the MCU chip 4, which automatically cuts off the gas supply and locks the valve. The first sensor 21 and the second sensor 22 collect ambient gas concentration data in real time. When the propane or methane content exceeds a set threshold, an abnormal signal is generated, and the MCU chip 4 automatically cuts off the gas supply, locks the valve, and activates the audible and visual alarm device.

[0033] Furthermore, the alarm module 3 is connected to the sensing module 1 and the detection module 2. When the sensing module 1 or the detection module 2 malfunctions, the alarm module 3 sends out an alarm.

[0034] Furthermore, the alarm module 3 has an LED 31. When the MCU chip 4 detects a fault, the LED 31 displays red; when the electronic control valve system automatically calibrates, the LED 31 displays yellow; when the electronic control valve system is in normal condition, the LED 31 displays green; and when the electronic control valve system performs self-testing, the LED 31 displays flashing green.

[0035] Furthermore, the alarm module 3 has a speaker 32, which sounds an alarm when the MCU chip 4 determines a fault.

[0036] exist Figure 1 In an optional embodiment, the MCU chip 4 is used to provide intelligent control, data processing, and response functions for the electronic control valve. The MCU chip 4 is connected to the sensing module 1, the detection module 2, and the alarm module 3. The MCU chip 4 receives and processes data from the sensing module 1 and the detection module 2. When the sensing module 1 determines that no human has entered for a certain period of time after determining that no one is present (the specific time is determined by those skilled in the art based on the circumstances), the MCU chip 4 controls the electronic control valve to close. When the detection module 2 senses that liquefied gas such as propane or natural gas such as methane exceeds the normal threshold range, the MCU chip 4 determines that a fault has occurred and controls the alarm module 3 to issue an alarm and close the electronic control valve.

[0037] Furthermore, the electronic control valve system includes a power converter 5, which converts external power into operating power. The power converter 5 refers to a device that converts input electrical energy into stable DC power that meets the equipment's operating requirements. Specifically, it can be implemented using an AC-DC conversion module combined with a voltage regulation circuit, for example, by combining a rectifier filter unit with a step-down chip to form a conversion structure adaptable to different input voltages. External power refers to power sources not generated internally by the system, specifically AC mains power or low-voltage DC power, such as 220V AC or 24V DC input.

[0038] exist Figure 1In an optional embodiment, the MCU chip 4 is connected to an external cloud platform 6, which is used to record the status of the MCU chip 4 and control the electronic control valve.

[0039] Furthermore, the MCU chip 4 is equipped with a delay module 7, and the cloud platform 6 controls the opening / closing of the delay module 7. When the delay function is enabled, both the sensing module 1 and the detection module 2 are active. When the delay function is disabled, the detection module 2 is active and the sensing module 1 is disabled.

[0040] Furthermore, the remote platform can be, but is not limited to, an app or client, allowing users to remotely check and control the system's information and its open / closed status.

[0041] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments. The above description is only a specific implementation of this application, but the protection scope of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
