Description

Technical Field

[0001] The present invention relates to the field of gas valves, and in particular to an intelligent gas control valve, a control system and a control method. Background Art

[0002] A gas valve is a safety device installed on gas pipelines. It's used to cut off, connect, and regulate gas flow in the pipeline, offering excellent control and sealing properties. It's suitable for use on pipelines carrying various fuel media, including city gas, liquefied petroleum gas, natural gas, and oxygen.

[0003] Conventional gas valves used in the prior art are all manually operated, which can easily lead to the following inconveniences during use. First, they are manually operated, making them very susceptible to misoperation. Second, because they can be operated at will, they are also susceptible to gas theft. Finally, in the event of a gas leak, conventional gas valves can only be manually closed to cut off the gas pipeline. In the event of a gas leak, there is no immediate way to detect it or cut off the gas pipeline, making it impossible to eliminate potential safety hazards.

[0004] In addition, traditional gas valves cannot be linked with other equipment and should be modified. Because they are not connected to the Internet, it is impossible to effectively monitor the gas valves and record data. Summary of the Invention

[0012] To achieve at least one objective of the present invention, the present invention provides an intelligent gas control valve. The intelligent gas control valve includes a valve body, a control unit, a valve core unit and an anti-tamper device. The control unit is electrically connected to the valve core unit. The valve core unit opens or closes the gas passage of the valve body according to the control signal of the control unit. The valve core unit includes a solenoid valve retaining ring, a solenoid valve sealing ring, a solenoid valve spring, a solenoid valve gland plate and an electromagnetic coil. The solenoid valve retaining ring is arranged in the valve body, and the solenoid valve sealing ring can cooperate with the solenoid valve retaining ring to open or close the gas passage by the solenoid valve sealing ring.

The anti-tamper device and the connecting end of the valve body connecting to the gas pipeline form a modular seal anti-tamper structure. The anti-tamper device is provided with a signal line, and the signal line is electrically connected to the control unit and forms a closed circuit. When the modular seal anti-tamper structure is damaged, the closed circuit is disconnected, the control unit sends a closing signal, and the electromagnetic coil controls the solenoid valve sealing ring to close the gas passage of the valve body, and then the gas supply is stopped.

[0013] In some embodiments, the intelligent gas control valve further includes a power supply unit, and the power supply unit is electrically connected to the control unit to provide electrical energy for the control unit.

[0014] In some embodiments, the valve body is provided with a mounting seat, the mounting seat has a mounting hole, and the mounting hole communicates with the gas passage of the valve body. The valve core unit is installed in the mounting hole and can realize the connection or disconnection of the gas pipeline through the gas passage of the valve body.

[0015] In some embodiments, the intelligent gas control valve further includes a gas valve cover. The gas valve cover is fixed to the valve body. The gas valve cover includes a cover body, and the cover body has a receiving cavity. The valve core unit and the control unit are installed in the receiving cavity to protect the valve core unit, the control unit and the power supply unit through the gas valve cover.

[0016] In some embodiments, the gas valve cover further includes a control button, which is disposed outside the gas valve cover and can control the disconnection or connection of the control unit.

[0017] In some embodiments, the intelligent gas control valve further includes an anti-disassembly protection sleeve, which is sleeved outside the anti-disassembly device.

[0018] According to another aspect of the present invention, there is also provided a control system for an intelligent gas control valve. The control system for the intelligent gas control valve includes: the intelligent gas control valve as described above and a remote gas data monitoring and control cloud. The intelligent gas control valve exchanges data with the remote gas data monitoring and control cloud. The control unit of the intelligent gas control valve includes a signal sending module, a signal receiving module, a gas monitoring module, a temperature detection module, and an analysis module. The control unit exchanges data with the remote gas data monitoring and control cloud through the signal sending module and the signal receiving module. The gas monitoring module monitors the gas concentration outside the intelligent gas control valve, and the temperature detection module monitors the temperature outside the intelligent gas control valve. The analysis module is electrically connected to the gas monitoring module and the temperature detection module respectively for communication. When the external gas concentration detected by the gas monitoring module is higher than a preset range or the external temperature detected by the temperature detection module is higher than a preset range, the analysis module sends a warning signal to the remote gas data monitoring and control cloud, and the remote gas data monitoring and control cloud sends a cut-off signal to the control unit to close the gas passage.

[0019] According to another aspect of the present invention, there is also provided a control system for an intelligent gas control valve. The control system for the intelligent gas control valve includes: a solenoid valve, an FSK (Frequency Shift Keying) NB (Narrow Band Internet of Things) composite wireless controller, and a remote gas data monitoring and control cloud. The solenoid valve performs opening and closing actions on the gas pipeline. The FSK NB composite wireless controller conducts data interaction and control with the remote gas data monitoring and control cloud. When the temperature or gas concentration outside the solenoid valve is higher than a preset range, the FSK NB composite wireless controller feeds back an alarm signal to the remote gas data monitoring and control cloud, and receives a gas cut-off instruction from the remote gas data monitoring and control cloud, and the solenoid valve closes the gas pipeline to cut off the gas supply. Wherein the FSK NB composite wireless controller includes a solenoid valve control circuit, an FSK circuit, an anti-theft monitoring wire, a gas control single-chip microcomputer, a temperature sensor, an NB module, and a battery and power conversion circuit. The anti-theft monitoring wire is electrically connected to the gas control single-chip microcomputer to form a closed circuit loop. The solenoid valve is provided with an anti-tamper seal, an anti-tamper clamp ring for the inlet pipe, and a valve body. The connecting devices at both ends of the valve body, the anti-tamper seal, the anti-tamper clamp ring for the inlet pipe, and the anti-theft monitoring wire are of a modular integrated structure. When the anti-theft monitoring wire is detached from the gas control single-chip microcomputer, the FSK circuit sends a signal to the solenoid valve control circuit to close the gas passage of the valve body, and at the same time feeds back abnormal information to the remote gas data monitoring and control cloud.

[0020] According to another aspect of the present invention, there is also provided a control method for an intelligent gas control valve. The control method for the intelligent gas control valve includes the following steps:

[0021] Set up an intelligent gas control valve user terminal and a remote gas data monitoring and control cloud. The intelligent gas control valve user terminal monitors in real time the solenoid valve operation data, gas usage data, external environment temperature data, external environment gas concentration data, and the state data of the anti-tamper closed loop. At the same time, it uploads the monitored data to the remote gas data monitoring and control cloud in real time, and opens or closes the solenoid valve according to the instructions of the remote gas data monitoring and control cloud to control the connection or cut-off of the gas.

[0022] When the intelligent gas control valve user terminal determines that the environmental temperature data is higher than the preset safe temperature range, or the external environment gas concentration data is higher than the preset safe concentration range, or the anti-tamper closed loop is cut off, it closes the solenoid valve to cut off the gas supply channel, and feeds back an alarm signal and abnormal data to the remote gas data monitoring and control cloud; and

[0023] Execute the user unique identifier, bind the unique gas user information to the unique solenoid valve. When the remote gas data monitoring and control cloud sends an instruction to turn on or off the gas supply to the user, the intelligent gas control valve user end identifies the gas user information in the instruction, opens or closes the solenoid valve that matches the gas user information, and turns on or off the gas supply to the corresponding gas user.

[0024] In some embodiments, the solenoid valve is implemented as the structure of the intelligent gas control valve described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations. The basic principles defined in the following description of the present invention can be applied to other implementation manners, variations, improvements, equivalent manners, and other technical solutions without departing from the spirit and scope of the present invention.

[0040] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" cannot be understood as a limitation on the number.

[0041] As Figures 1 to 11 shown is a preferred embodiment of an intelligent gas control valve 10 based on the present invention. The gas control valve 10 is used to achieve intelligent control of a gas pipeline, such as remote control of the gas pipeline, including opening and closing, etc.

[0042] Specifically, the intelligent gas control valve 10 includes a valve body 11, a power supply unit 13, a control unit 15, and a valve core unit 12. The power supply unit 13, the control unit 15, and the valve core unit 12 are respectively arranged in the valve body 11, and the power supply unit 13 and the control unit 15 can be electrically connected to provide electrical energy for the control unit 15. The valve core unit 12 and the control unit 15 are electrically connected to perform opening or closing actions according to the signal transmitted by the control unit 15 received.

[0043] More specifically, the valve body 11 has a channel 110, and a connecting device 111 is provided at each end of the valve body 11. The two ends of the valve body 11 can be respectively connected to the gas pipeline through the two connecting devices 111, so that the channel 110 of the valve body 11 is communicated with the gas pipeline, thereby achieving the function of closing the gas pipeline as long as the channel 110 in the valve body 11 is closed. Preferably, in a preferred embodiment of the present invention, the connecting device 111 is provided as a threaded interface, that is, the valve body 11 can be threadedly connected to the gas pipeline through the threaded interfaces at its two ends respectively. Due to the threaded connection, the installation is very simple and fast, and the applicable range is also very wide, and it can be applied to gas pipelines of different sizes. Those skilled in the art can understand that the type of the connecting device 111 at the two ends of the valve body 11 can be selected or changed according to the actual situation, including but not limited to connection methods with good sealing performance such as flange connection and socket connection. In other words, as long as on the basis of the above disclosure of the present invention, a technical solution identical or similar to the present invention is adopted, the same or similar technical problems as those of the present invention are solved, and the same or similar technical effects as those of the present invention are achieved, they all fall within the protection scope of the present invention, and the specific implementation manners of the present invention are not limited thereto. It is worth mentioning that preferably, since the connecting device 111 provided at the two ends of the valve body 11 adopts a threaded connection, the mechanical interface has high compatibility and can be applied to gas pipelines of different specifications.

[0044] Furthermore, the intelligent gas control valve 10 further includes an anti-disassembly device 16, and the anti-disassembly device 16 is disposed on the valve body 11 and sealed with a lead seal at the connecting device 111. Since the anti-disassembly device 16 is sealed with a lead seal on the connecting device 111 of the intelligent gas control valve 10, the intelligent gas control valve 10 cannot be disassembled from the gas pipeline.

[0045] In a specific embodiment, preferably, the anti-disassembly device 16 is provided with two signal lines 161, and the two signal lines 161 are electrically connected to the control unit 15, and a circuit closed loop is formed between the control unit 15 and the anti-disassembly device 16 through the two signal lines 161. Since the anti-disassembly device 16 is lead-sealed on the connecting device 111 of the intelligent gas control valve 10, the intelligent gas control valve 10 cannot be disassembled from the gas pipeline. When someone wants to forcibly remove the intelligent gas control valve 10, it is inevitable to damage the anti-disassembly device 16 to release the connection of the connecting device 111. At this time, the two signal lines 161 on the anti-disassembly device 16 will also be disconnected from the control unit 15 or from the anti-disassembly device 16, thus destroying the closed loop. Once the closed loop is destroyed, after receiving the signal, the control unit 15 will send a signal to the electromagnetic coil 125 to control the solenoid valve sealing ring 122 to close the passage 110, and then close the gas pipeline.

[0046] Further, an installation seat 112 is provided on the valve body 11, and the installation seat 112 has an installation hole 1120, and the installation hole 1120 communicates with the passage 110. The spool unit 12 is installed in the installation hole 1120 and can realize the connection or disconnection of the gas pipeline through the passage 110. More specifically, the spool unit 12 includes a solenoid valve retaining ring 121, a solenoid valve sealing ring 122, a solenoid valve spring 123, a solenoid valve gland plate 124, and an electromagnetic coil 125. The solenoid valve retaining ring 121 is disposed in the installation hole 1120 of the installation seat 112, and the solenoid valve sealing ring 122 can cooperate with the solenoid valve retaining ring 121 to close the passage 110 with the solenoid valve sealing ring 122. The electromagnetic coil 125, the solenoid valve gland plate 124, and the solenoid valve spring 123 are connected in sequence, and the electromagnetic coil 125 can drive the solenoid valve sealing ring 122 to move up and down through the solenoid valve gland plate 124 and the solenoid valve spring 123 under the control of the control unit 15.

[0047] Further, the intelligent gas control valve 10 further includes a gas valve cover 14, which is fixed to the valve body 11. The gas valve cover 14 includes a cover body 141, and the cover body 141 has a first accommodation cavity 1401 and a second accommodation cavity 1402. Wherein, the valve core unit 12 and the control unit 15 are installed in the first accommodation cavity 1401, and the power supply unit 13 is installed in the second accommodation cavity 1402. Thus, the valve core unit 12, the control unit 15 and the power supply unit 13 are protected by the gas valve cover 14, preventing the valve core unit 12, the control unit 15 and the power supply unit 13 from being contaminated by oil stains, water stains, etc., and avoiding poor contact or short circuit, thereby improving the service life of the valve core unit 12, the control unit 15 and the power supply unit 13.

[0048] Further, the intelligent gas control valve 10 further includes at least one battery sheath 132. The battery 131 is installed in the battery sheath 132, and the battery sheath 132 is installed in the second accommodation cavity 1402 of the gas valve cover 14, so as to provide protection for the battery 131 to avoid damage to the battery 131 from the outside.

[0049] Further, the gas valve cover 14 further includes a battery pressing plate 142. The battery pressing plate 142 is detachably connected to the end face of the second accommodation cavity 1402 of the gas valve cover 14, so as to close the second accommodation cavity 1402 through the battery pressing plate 142, prevent the battery 131 and the battery sheath 132 from falling off the second accommodation cavity 1402, and protect the service life of the battery 131 and the battery sheath 132.

[0050] Further, the gas valve cover 14 further includes a control button 143. The control button 143 is arranged on the outside of the gas valve cover 14 and the control button 143 can control the disconnection or connection of the power supply unit 13 and the control unit 15. Thus, the user can control the power supply unit 13 to supply power to the control unit 15 by pressing the control button 143, and further control the opening and closing of the valve core unit 12.

[0051] In addition, those skilled in the art can also control the power supply unit 13 in other ways, such as changing from a mechanical button to a touch button, etc., which all fall within the protection scope of the present invention. The specific implementation manners of the present invention are not limited thereto.

[0052] Next, the working process of the intelligent gas control valve 10 of the present invention will be further briefly described in conjunction with the drawings.

[0053] When the intelligent gas control valve 10 needs to work, press the control button 143 to make the power supply unit 13 supply power to the control unit 15. At this time, the power supply unit 13 sends an electromagnetic signal to the electromagnetic coil 125. After receiving the electromagnetic signal, the electromagnetic coil 125 generates a magnetic field. Through the generated magnetic field, the solenoid valve sealing ring 122 is lifted from the mounting hole 1120 of the valve body 11. At this time, the spool unit 12 opens, and the passage 110 on the valve body 11 is communicated, and the entire gas pipeline forms a passage for the smooth supply of gas.

[0054] When power-off is required, press the control button 143 again to disconnect the power supply unit 13 from the control unit 15. At this time, the electromagnetic force of the electromagnetic coil 125 disappears, and the spring presses the solenoid valve sealing ring 122 into the mounting hole 1120 of the valve body 11. At this time, the spool unit 12 closes, thus cutting off the passage of the gas pipeline.

[0055] It is worth mentioning that the intelligent gas control valve 10 is also provided with an anti-disassembly protection sleeve 17. The anti-disassembly protection sleeve 17 is sleeved outside the anti-disassembly device 16 to protect the anti-disassembly device 16 and further achieve anti-disassembly. Preferably, the anti-disassembly protection sleeve 17 is implemented as Figure 11 the shown split anti-disassembly sleeve. After every two semi-circular split anti-disassembly sleeves are matched together, they are sleeved outside the anti-disassembly device 16, and bolts and nuts are preferably used for connection.

[0056] According to another aspect of the present invention, a control system of an intelligent gas control valve based on a preferred embodiment of the present invention is also described. The control system of the intelligent gas control valve includes an intelligent gas control valve, a wireless gateway, and a gas leakage monitor. In the present invention Figures 1 to 11 each component of the intelligent gas control valve 10 can be implemented in the control system of the intelligent gas control valve.

[0057] Specifically, in a preferred embodiment of the control system of the intelligent gas control valve of the present invention, as Figure 12 shown, in this embodiment of the control system of the intelligent gas control valve of the present invention, the intelligent gas control valve is implemented as an FSK (Frequency-shift keying) + NB (Narrow Band Internet of Things, NB-IoT) wireless controller (defined as an FSK frequency-shift keying NB narrow band Internet of Things composite wireless controller) and a solenoid valve. Under the control of the FSK + NB wireless controller, the solenoid valve performs opening and closing actions on the gas pipeline, thereby cutting off or connecting the supply of gas. The wireless gateway is implemented as a 4G gateway.

[0058] More specifically, the FSK+NB wireless controller controls the solenoid valve and monitors whether there are abnormal gas theft behaviors in the pipeline through a monitoring switch. It obtains whether the gas concentration exceeds the standard from the gas leakage monitor through FSK wireless, so as to perform linkage control on the solenoid valve. If in a scenario with poor NB signal, the FSK+NB wireless controller also communicates with the 4G gateway.

[0059] The control system of the intelligent gas control valve further includes a remote gas data monitoring and control cloud. The FSK+NB wireless controller performs data interaction and control with the remote gas data monitoring and control cloud. The FSK+NB wireless controller is provided with a temperature sensor, which can monitor the temperature of the location where the intelligent gas control valve is located in real time. When the temperature exceeds the threshold, the FSK+NB wireless controller performs linkage control on the solenoid valve and feeds back to the remote gas data monitoring and control cloud through the 4G gateway.

[0060] The gas leakage monitor monitors gas leakage. When it detects that the gas concentration exceeds the standard, it reports to the FSK+NB wireless controller. The FSK+NB wireless controller performs linkage control on the solenoid valve and feeds back to the remote gas data monitoring and control cloud through the 4G gateway.

[0061] Specifically, the gas leakage monitor includes a leakage monitoring sensor, a gas leakage monitoring single-chip microcomputer, an FSK communication module, a gas leakage monitoring power supply module, and a battery and charging circuit that are electrically connected to each other. The communication between the FSK+NB wireless controller and the gas leakage monitor is completed through FSK wireless technology. Those skilled in the art can understand that the gas leakage monitor can be set as a device with a separate entity structure and communicate with the FSK+NB wireless controller through FSK wireless technology. Of course, the gas leakage monitor can also be implemented as each functional module directly integrated into the FSK+NB wireless controller of the intelligent gas control valve. In this case, the overall modular setting is more convenient for installation.

[0062] More specifically, in a preferred embodiment of the control system of the intelligent gas control valve of the present invention, as Figure 12As shown, the FSK+NB wireless controller of the intelligent gas control valve includes a solenoid valve control circuit, an FSK circuit, an anti-theft monitoring wire, a gas control single-chip microcomputer, a temperature sensor, an NB module, and a battery and power conversion circuit. The anti-theft monitoring wire is electrically connected to the gas control single-chip microcomputer to form a closed circuit loop. The solenoid valve is provided with an anti-tamper seal, an anti-tamper clamp ring for the inlet pipe, and a valve body. The connecting devices at both ends of the valve body, the anti-tamper seal, the anti-tamper clamp ring for the inlet pipe, and the anti-theft monitoring wire are of a modular integrated structure. When someone wants to forcibly remove the intelligent gas control valve, it is inevitable to damage the modular integrated structure formed by the connecting devices at both ends of the valve body, the anti-tamper seal, the anti-tamper clamp ring for the inlet pipe, and the anti-theft monitoring wire. At this time, the anti-theft monitoring wire will also be separated from the gas control single-chip microcomputer, thereby destroying the closed circuit loop. Once the closed circuit loop is damaged, after the FSK circuit receives a signal, it will send a signal to the solenoid valve control circuit to close the channel of the valve body, and then close the gas pipeline, while feedbacking abnormal information to the remote gas data monitoring and control cloud.

[0063] The connection between the valve of the intelligent gas control valve and the pipeline is integrally anti-tamper. The modular integrated structure is physically sealed against tampering, and a forced removal signal is alarmed. The anti-tamper seal can not only achieve physical anti-removal. When a gas user forcibly removes it privately, the 2 anti-theft monitoring wires are separated, and the valve will be automatically closed and locked, stopping the manual on-site operation of the gas user, and sending an alarm signal to the remote gas data monitoring and control cloud.

[0064] Preferably, the intelligent gas control valve is provided with a battery, such as a lithium battery CR17450, and the FSK+NB wireless controller is implemented to be powered by the lithium battery CR17450. When the wireless gateway is implemented as a 4G gateway, the FSK+NB wireless controller communicates with the 4G gateway wirelessly through FSK 433MHz, reports the status to the 4G gateway, and receives control instructions from the 4G gateway. The FSK+NB wireless controller also judges whether there is gas theft, etc. through the anti-theft monitoring wire, and can also monitor the temperature inside the gas meter box and close the solenoid valve in case of abnormality. It can be understood that the communication between the FSK+NB wireless controller and the gas leakage monitor is completed through FSK wireless. It can be understood that the FSK+NB wireless controller adopts a low-power design, and one CR17450 battery can support the FSK+NB wireless controller to be used for 2 years, and the solenoid valve can be normally opened and closed at least 10 times within 2 years.

[0065] More specifically, in a preferred embodiment of the control system of the intelligent gas control valve of the present invention, as Figure 13As shown, the gas leakage monitor is also implemented to include a buzzer and light alarm indication circuit, a gas leakage detection sensor, a gas leakage monitoring single-chip microcomputer, an FSK communication module, a battery and charging circuit, and a 220VAC to DC5V power module. The power module is powered by 220V, powered by alternating current during normal operation, and charges the battery at the same time. The gas leakage detection sensor continuously monitors gas for 24 hours. When externally powered, the monitoring frequency can be implemented as once every 5 minutes or shorter, and once every half hour or shorter when powered by the battery. When gas leakage is detected, the buzzer and light alarm indication circuit prompts the user through lights and buzzer. It can be understood that in the case of power failure, the battery powers to ensure that gas leakage monitoring and data for 1-2 days can be timely fed back and reported to the remote gas data monitoring and control cloud. It can be understood that the gas leakage monitor and the intelligent gas control valve perform data communication wirelessly via FSK 433MHz. When gas leakage is detected, the intelligent gas control valve can timely shut off the gas in real time.

[0066] More specifically, in a preferred embodiment of the control system of the intelligent gas control valve of the present invention, as Figure 14 shown, when the wireless gateway is implemented as a 4G gateway, the 4G gateway is specifically implemented to include a 220V and POE power conversion circuit, an FSK circuit, a WIFI / Bluetooth SOC, a 4G module, a 485 interface, and an RJ45 interface. Specifically, the 4G gateway receives messages from the FSK+NB wireless controller and sends control instructions to remotely control the FSK+NB wireless controller via an FSK wireless local area network downward, and performs data interaction with the remote gas data monitoring and control cloud via the 4G module upward. In a specific implementation, a single 4G gateway can be connected to and communicate with multiple FSK+NB wireless controllers. Thus, the remote gas data monitoring and control cloud can monitor the on / off control of the corresponding solenoid valves by multiple FSK+NB wireless controllers and the gas usage of each gas user. It can be understood that the 4G gateway is provided with rich external interfaces, such as having a 485 interface and an RJ45 network interface at the same time, which is convenient for docking with other devices. It can be understood that the setting of the 220V and POE power conversion circuit enables the power supply to support 220V power supply and POE power supply.

[0067] It is worth mentioning that the remote gas data monitoring and control cloud can remotely control the valve to close or open, thereby realizing the cut-off or opening of the gas. In specific applications, gas users can either perform local control on-site or remotely control through the remote gas data monitoring and control cloud. Of course, the remote gas data monitoring and control cloud can also close the local control permission of the gas user on-site. For example, when the gas is in use at home and in case of an emergency such as the user going out without a key, the user can contact the gas company, and the gas company can close the gas through the remote gas data monitoring and control cloud to avoid gas accidents.

[0068] It can be understood that Figures 12 to 14 in the embodiments of Figures 1 to 11 in the smart gas control valve 10 of the present invention, all other components except the power supply unit 13, the control unit 15, and the anti-tampering device 16 can be directly implemented in the control system of the smart gas control valve.

[0069] In addition, according to another aspect of the present invention, when the smart gas control valve in the control system of the smart gas control valve of the present invention is specifically implemented as Figures 1 to 11 the smart gas control valve 10 in the present invention, that is, when the control system of the smart gas control valve includes the power supply unit 13, the control unit 15, and the anti-tampering device 16 of the smart gas control valve 10, the control unit 15 is electrically connected to the power supply unit 13, and the electromagnetic coil 125 in the spool unit 12 of the control unit 15 and the remote gas data monitoring and control cloud are respectively communicatively connected, so that the electromagnetic coil 125 can receive signal instructions from the control unit 15, and the control unit 15 can also exchange data with the remote gas data monitoring and control cloud.

[0070] Specifically, in this specific embodiment, the control unit 15 includes a signal sending module and a signal receiving module. The signal sending module and the signal receiving module are respectively communicatively arranged in the control unit 15. The control unit 15 sends and receives information through the signal sending module and the signal receiving module, so as to realize data exchange with the remote gas data monitoring and control cloud and the like.

[0071] The control unit 15 further includes a gas monitoring module. The gas monitoring module is electrically arranged in the control unit 15, so that the control unit 15 can monitor the gas concentration around the smart gas control valve 10 at any time and send the gas concentration to the control unit 15.

[0072] Further, the control unit 15 further includes a temperature detection module, which is electrically disposed in the control unit 15 so that the control unit 15 can monitor the temperature around the intelligent gas control valve 10 at any time.

[0073] The control unit 15 further includes an analysis module, which is electrically disposed in the control module and is communicatively connected to the gas monitoring module and the temperature detection module respectively. The analysis module is also communicatively connected to the remote gas data monitoring and control cloud (such as the gas company, the gas provider), so as to send the analysis result to the remote control center in a timely manner.

[0074] When the gas monitoring module monitors the gas concentration around the intelligent gas control valve 10 and sends it to the control unit 15, the analysis module in the control unit 15 will compare the received concentration data with the system set value.

[0075] When the gas concentration around the intelligent gas control valve 10 received by the control module is lower than the system set value, the intelligent gas control valve 10 operates normally; when the gas concentration value received by the control module is higher than the system set value, the analysis module will send this value to the remote gas data monitoring and control cloud. At this time, the remote gas data monitoring and control cloud will send a signal to the control unit 15 to control the intelligent gas control valve 10 to cut off the gas passage 110 through the control unit 15, thereby avoiding accidents.

[0076] When the analysis module analyzes that the air temperature detected by the temperature detection module around the intelligent gas control valve 10 is less than the system set value, the intelligent gas control valve 10 operates normally; when the analysis module analyzes that the temperature detected by the temperature detection module around the intelligent gas control valve 10 is greater than the system set value, the analysis module will send this value to the remote gas data monitoring and control cloud. At this time, the remote control center will send a signal to the control unit 15 to control the intelligent gas control valve 10 to cut off the gas passage 110 through the control unit 15, thereby avoiding accidents.

[0077] Further, the intelligent gas control valve 10 includes an alarm (not shown in the figure), and the alarm is set to be communicatively connected to the control unit 15 so as to receive the information sent by the control unit 15. When the analysis module concludes through comparison that the temperature around the intelligent gas control valve 10 is higher than the system set value, on the one hand, it will send a signal to the control unit 15 to close the valve core unit 12 through the control unit 15; at the same time, the analysis module will send a signal to the alarm, and the alarm will issue a corresponding alarm after receiving the alarm signal.

[0078] In an embodiment of the present invention, the alarms issued by the alarm device include but are not limited to sounds, texts, pictures and their combinations, such as beeping and light alarm indicators, etc., so that the user can learn about the situation occurring in the house in the first time.

[0079] In addition, those skilled in the art can determine the alarm device and its alarm mode according to the actual situation. For example, the client intelligent device is communicatively connected to the control unit 15. When the analysis module analyzes that an accident occurs, the accident signal can be sent to the client intelligent device in the first time, so that the user can learn about the accident and the corresponding data in the first time.

[0080] The interaction between the control unit 15 and the remote gas data monitoring and control cloud is through the operator's 4G network, ensuring the timeliness, stability and reliability of command sending and data reporting.

[0081] The power supply unit 13 is implemented as a battery 131, and the battery 131 is a low-power built-in battery 131, so as to ensure a service life of 24 months and 1-2 operations such as remotely starting and switching valves.

[0082] In an embodiment of the present invention, the monitoring frequency of the control unit 15 for the gas concentration and the surrounding temperature is set to be monitored once every 10 minutes. However, the specific implementation manner of the present invention is not limited thereto. Those skilled in the art can set the monitoring frequency of the gas concentration and the surrounding temperature according to the actual situation, and can also set other interaction modes between the control unit 15 and the remote gas data monitoring and control cloud according to the actual situation or customer requirements, such as 5G network or Bluetooth connection, etc., or change the type of the alarm device, etc.

[0083] In other words, as long as on the basis of the above disclosure of the present invention, the same or similar technical solutions are adopted, the same or similar technical problems are solved, and the same or similar technical effects are achieved, they all fall within the protection scope of the present invention. The specific implementation manner of the present invention is not limited thereto.

[0084] It should be noted that when someone wants to forcibly remove the intelligent gas control valve 10, they will inevitably damage the anti-disassembly device 16 to release the connection of the connecting device 111. At this time, the two signal lines 161 on the anti-disassembly device 16 will also be disconnected from the control unit 15 or from the anti-disassembly device 16, thus breaking the closed loop. Once the closed loop is broken, after receiving the signal, the control unit 15 will send a signal to the electromagnetic coil 125 to control the solenoid valve sealing ring 122 to close the channel 110, and then close the gas pipeline. At the same time, the control unit 15 will transmit the information to the remote gas data monitoring and control cloud, so that the remote control center can timely learn about the unexpected situation of the intelligent gas control valve 10, thus preventing the intelligent gas control valve 10 from being stolen or disassembled.

[0085] It is worth mentioning that once the closed loop between the anti-disassembly device 16 and the control unit 15 is interrupted, the control unit 15 will not only control the intelligent gas control valve 10 to close, but also directly lock the movement of the valve core unit 12, that is, the valve core unit 12 cannot be manually opened anymore, thus preventing situations such as gas theft.

[0086] According to another aspect of the present invention, a control method for an intelligent gas control valve is also provided. The control method for the intelligent gas control valve of the present invention is an invention related to a computer program, which elaborates a solution for controlling or processing external or internal objects of a computer by executing a computer program compiled according to the above process based on the computer program processing flow to solve the problems proposed by the present invention. Through the control method for the intelligent gas control valve of the present invention, the intelligent gas control valve can be remotely controlled, and the opening and closing conditions of the intelligent gas control valve and data such as gas usage conditions can be monitored and recorded in real time. It can also alarm when it is monitored that the intelligent gas control valve is manually disassembled or gas leakage and / or fire occur, and remotely cut off the gas supply.

[0087] Specifically, the control method for the intelligent gas control valve includes the following steps:

[0088] Set up an intelligent gas control valve user terminal and a remote gas data monitoring and control cloud. The intelligent gas control valve user terminal monitors the solenoid valve operation data, gas usage data, external environment temperature data, external environment gas concentration data, and the state data of the anti-disassembly closed loop in real time, and at the same time uploads the monitored data to the remote gas data monitoring and control cloud in real time, and opens or closes the solenoid valve according to the instructions of the remote gas data monitoring and control cloud to control the connection or disconnection of the gas.

[0089] When the intelligent gas control valve's user end determines that the ambient temperature data is higher than the preset safe temperature range, or the external ambient gas concentration data is higher than the preset safe concentration range, or the anti-tamper closed loop is cut off, it closes the solenoid valve to cut off the gas supply channel, and feeds back an alarm signal and abnormal data to the remote gas data monitoring and control cloud; and

[0090] Execute the user's unique identifier, bind the unique gas user information to the unique solenoid valve. When the remote gas data monitoring and control cloud sends an instruction to connect or cut off the gas supply of the user, the user end of the intelligent gas control valve identifies the gas user information in the instruction, opens or closes the solenoid valve that matches the gas user information, and connects or cuts off the gas supply of the corresponding gas user.

[0091] Furthermore, the control method of the intelligent gas control valve further includes the following steps: when the user end of the intelligent gas control valve receives the abnormal gas data from the leakage monitoring sensor, it closes the solenoid valve to cut off the gas supply channel, obtains the gas user information of the solenoid valve that is closed, and feeds it back to the remote gas data monitoring and control cloud and the authorized intelligent device end of the gas user.

[0092] Furthermore, the control method of the intelligent gas control valve further includes the following steps: the user end of the intelligent gas control valve sets a signal sending module, a signal receiving module, a gas monitoring module, and a temperature detection module. The signal sending module and the signal receiving module send and receive information, and perform data exchange with the remote gas data monitoring and control cloud; the gas monitoring module monitors the external ambient gas concentration data in real time; the temperature detection module monitors the external ambient temperature data in real time.

[0093] Furthermore, the control method of the intelligent gas control valve further includes the following steps: the user end of the intelligent gas control valve sets an analysis module. The external ambient gas concentration data monitored by the gas monitoring module in real time and the external ambient temperature data monitored by the temperature detection module in real time are sent to the analysis module, and the analysis module performs analysis and judgment: whether the ambient temperature data is higher than the preset safe temperature range and whether the external ambient gas concentration data is higher than the preset safe concentration range. Among them, when the analysis module determines that the ambient temperature data is higher than the preset safe temperature range or the external ambient gas concentration data is higher than the preset safe concentration range, the signal sending module sends an alarm message and abnormal data to the remote gas data monitoring and control cloud.

[0094] Furthermore, the control method of the intelligent gas control valve further includes the following steps: the analysis module performs the on-off monitoring step of the anti-tamper closed loop. When the anti-tamper closed loop is abnormally cut off, the valve of the solenoid valve is immediately locked, and at the same time, the signal sending module immediately sends an alarm signal and abnormal data to the remote gas data monitoring and control cloud.
