Abstract

The present invention provides a composite communication control smart valve and a control method thereof, which can continuously and instantly execute core security functions such as leak detection and cut-off through an independent near field communication path even if the Internet connection is unstable or a server malfunctions, thereby improving safety and reliability. Even in the case of a power failure in which a main power source is cut off, a leakage cut-off operation can be stably completed with minimum power consumption by using a built-in emergency power source and a low-power-consumption pulse-driven valve drive unit, and particularly, a solution is provided not only for network and power source failures, but also for power failure. In addition, the user can perform physical operation even under the worst condition that a control system or a driving part breaks down or the like.

Description

Technical Field

[0001] This invention relates to a smart valve technology that can automatically cut off fluids when leaks occur, such as water or gas, thereby preventing floods and gas accidents in homes or buildings. In particular, it relates to a highly reliable composite communication control smart valve with multi-level safety protection mechanisms, which can reliably perform core functions such as leak cut-off even in emergency situations such as network failures or power outages. Background Technology

[0002] Manual valves that require direct operation by personnel on-site are far removed from remote control or automation.

[0003] For example, Chinese patent CN113494638A points out that if a manual valve for a household leaks when no one is home, it cannot be shut off in time, which can easily cause serious property damage or safety accidents, and has obvious limitations.

[0004] Replacing a manual valve with an electric valve usually requires the installation of an additional electric actuator, which often involves high costs and complex construction procedures such as pipeline modification, making it difficult to implement in practice.

[0005] Electric valves (motor-driven valves) emerged to automate valve operation. They enable remote opening and closing control of valves via electric motors, but they are highly dependent on wired connections.

[0006] Currently, devices such as solenoid valves in industrial settings typically receive control signals and perform actions via wiring. Therefore, early automation systems required wiring installation, making operation and maintenance relatively complex.

[0007] In addition, its power supply also relies on the external power grid, which means that automated control can only be achieved in places near power lines, thus limiting its application scope.

[0008] In fact, according to the US Patent Publication US20140130878A1, valve automation in crude oil pipelines requires a large amount of electricity under high-pressure driving conditions, and therefore must rely on nearby power lines for power supply. At the same time, in some areas, there are limitations such as remote control signals not being able to be transmitted smoothly due to communication blind spots.

[0009] In other words, wired electric valve systems are only feasible within the scope of available physical power and communication infrastructure, and their intelligent control functions are also significantly limited. To overcome these problems, the industry has also developed wireless valve control technology utilizing radio frequency (RF) to improve installation flexibility. For example, US Patent Publication US20110121215A1 discloses a technical solution that integrates a wireless receiver module on the valve body and combines it with battery power to receive wireless control signals from the outside via ZigBee communication, thereby realizing the opening and closing control of the solenoid valve.

[0010] This method reduces wiring and lowers the manpower and costs required for installation and maintenance. However, since this type of RF remote control is typically based on short-range communication, its communication distance is significantly limited. In other words, when the distance between a transmitter and the valve exceeds a certain range, signal sensitivity decreases or even disappears, making long-distance control impossible.

[0011] In fact, the aforementioned US20140130878A1 document also clearly points out that data transmission will be limited in communication blind spots where remote GPRS wireless signals cannot reach. This indirectly proves that it is difficult to achieve valve control over a wide area by relying solely on short-range wireless systems.

[0012] In recent years, with the rapid development of Internet of Things (IoT) technology, smart valves capable of monitoring and controlling valve status from any remote location via a network have gradually emerged. IoT smart valves typically incorporate communication modules on sensors and actuators, establishing connections with user terminals through wired or wireless networks and cloud servers, thereby achieving real-time control without physical distance limitations. For example, Chinese utility model CN204533739U discloses an IoT-based valve control system that uses Wi-Fi or ZigBee communication modules and gateways to remotely control the opening and closing of radiator valves for heating systems.

[0013] Furthermore, the prior art described in the background section of US Patent Publication US20140130878A1 also proposes a system for remotely controlling valves via a web page using a valve controller with a built-in internet web server. Therefore, smart valves combined with IoT technology, through cloud server linkage or smartphone applications, enable users to monitor and control valve status in real time from a distance, effectively overcoming the limitations of existing wired and short-range wireless control in terms of communication distance.

[0014] However, the adoption of IoT-based valve control has also exposed new problems.

[0015] First, this method is highly dependent on the internet and cloud platforms. If the network is unstable or the server malfunctions, remote control itself cannot be achieved. In other words, an internet connection must be maintained at all times, and in the event of a network outage, there is a lack of effective means to control the valves on-site, which presents significant limitations.

[0016] Furthermore, smart valve devices typically require a continuous power supply, thus posing a risk of malfunction during power outages. While some existing technologies incorporate battery backups and safety measures such as automatic valve shut-off in case of power loss, they fundamentally remain dependent on external power grids.

[0017] Meanwhile, since the control process needs to be completed via the Internet, network latency is likely to occur, making it difficult to drive the valve in a timely manner in emergency situations; in addition, relying on cloud services may also introduce incidental problems such as network security risks and increased operation and maintenance costs.

[0018] In summary, existing technologies such as manual valves, wired electric valves, RF short-range wireless control systems, and IoT-connected smart valves all have inherent limitations and drawbacks. For example, they cannot be operated when no one is present, they rely on wiring infrastructure, communication distances are limited, and they are highly dependent on the internet and power supply. These issues make the need for more reliable and intelligent remote valve control technologies increasingly urgent.

[0019] Therefore, it is necessary to propose an improved intelligent valve and its valve control system that can solve the above-mentioned problems of the existing technology. Summary of the Invention

[0020] Technical problems to be solved The present invention is proposed in view of the aforementioned problems, and its purpose is to provide a composite communication control smart valve that can continuously and instantly perform core safety functions such as leak detection and shut-off through an independent short-range communication path, even when the Internet connection is unstable or the server fails.

[0021] Furthermore, the present invention also provides a composite communication control smart valve that can stably complete the leakage shut-off action with minimal power consumption even in the event of a power outage when the main power supply is cut off, by utilizing a built-in emergency power supply and a valve drive unit with a low-power pulse drive mode.

[0022] Furthermore, the present invention provides a composite communication control smart valve that not only provides solutions for network and power failures, but also ensures the reliability of the system under any abnormal or exceptional circumstances by setting up multi-level fail-safe means that allow users to perform physical operations, even in the worst case where the control system or drive unit itself fails.

[0023] Technical solution To address the aforementioned technical challenges, a composite communication control smart valve according to an embodiment of the present invention includes: a valve body 100 having a flow path for fluid flow; a valve drive unit 120 coupled to the valve body 100 and used to open or close the flow path; and a valve control unit 140 for controlling the valve drive unit 120 and having an IoT communication unit for communicating with a remote server and an RF communication unit for communicating with near-field devices 200 and 300.

[0024] The valve control unit 140 further includes: a non-volatile memory for storing instructions; and a processor connected to the execution of the instructions.

[0025] When executing the instructions, the processor is configured to perform the following operations: periodically monitor the communication status between the IoT communication unit and the remote server; and, based on the monitoring results, when a communication interruption status is detected where no response is received from the remote server within a preset time, responsively switch the control mode of the valve drive unit 120 from the control mode based on the IoT communication unit to the local control mode via the RF communication unit.

[0026] The proximity device includes a wireless leak detector 200 for detecting leaks, and the processor can also be configured to treat a leak detection signal received from the wireless leak detector 200 via the RF communication unit as a Highest Priority Interrupt and drive the valve drive unit 120 to the cut-off position, regardless of the connection status of the IoT communication unit or other tasks currently being performed.

[0027] The valve drive unit 120 includes a coil that generates a driving force when energized. The processor is further configured to: during the operation of the valve drive unit 120, sample the driving current flowing through the coil in real time to generate a current waveform, determine whether the rise time of the generated current waveform is delayed relative to a pre-stored reference time, or whether the peak current exceeds a pre-stored threshold, and generate a fault diagnosis signal based on the determination result.

[0028] The processor can also be configured to: send a preventive maintenance alarm through the IoT communication unit when generating the fault diagnosis signal, and immediately cut off the power supply to the valve drive unit 120 for circuit protection when the peak current exceeds the danger level.

[0029] The intelligent valve further includes a pipe connector disposed at at least one end of the valve body 100, wherein the pipe connector may include: an O-ring 102 for sealing a pipe inserted into and disposed inside the valve body; a clamping member 105 for clamping the outer circumferential surface of the pipe to prevent it from dislodging; and a cap 104 coupled to the end of the valve body for supporting the clamping member and the O-ring.

[0030] The cover 104 may also include a wiping lip made of elastic material disposed on its inner side. When the tube is inserted, the wiping lip fits tightly against the outer peripheral surface of the tube, thereby wiping off foreign objects on the surface of the tube.

[0031] It also includes: a main power supply unit 150 for continuously supplying power to the valve control unit 140, and an emergency power supply unit 152 for supplying power to the valve control unit when the main power supply unit is powered off. The valve drive unit 120 includes a latching solenoid, which switches its state only when power is applied and maintains its current state by the magnetic force of a permanent magnet when power is off. The processor 145 is further configured to apply a pulse signal to the latching solenoid using the power of the emergency power supply unit 152 when a power failure is detected in the main power supply unit, thereby switching the valve to the closed state.

[0032] The latching electromagnet includes: a coil body 131 with a coil wound inside; a plunger 124 that reciprocates axially inside the coil body; a guide valve core 125 for inserting into and guiding the plunger 124; and a permanent magnet 127 fixed to the lower part of the coil body; wherein a diaphragm 121 may be arranged between the valve body 100 and the coil body 131, and the diaphragm is pressurized by the plunger 124 to close the flow path.

[0033] In addition, a housing 112 is included to accommodate the internal space of the valve drive unit 120 and the valve control unit 140. On the outer side of the housing 112, an exposed manual operation button 113 may be provided so that the user can manually operate the valve drive unit 120 when the valve control unit 140 fails to work properly.

[0034] The wireless water leakage detector 200 may include: a lower shell 201 and an upper shell 209 that are joined together; a waterproof O-ring 204 disposed between the lower shell and the upper shell; a pair of sensing rods 206 that penetrate the lower shell and protrude outward and are electrically conductive when in contact with fluid; and a detection control circuit section 207 housed within the lower shell 201 and the upper shell 209.

[0035] A control method for a composite communication-controlled smart valve according to an embodiment of the present invention includes: a step of valve control unit 140 periodically monitoring the communication status with a remote server via IoT communication unit 147; a step of automatically switching the control mode from the IoT communication unit-based control mode to a local control mode via RF communication unit when the valve control unit 140 detects a communication interruption state in which no response is received from the remote server within a preset time; and a step of interrupting the currently executed operation and driving valve drive unit 120 to a closed state with the highest priority when a leakage detection signal is received from a proximity device 200, 300 via the RF communication unit.

[0036] The above method may further include the step of: during the operation of the valve drive unit 120, the valve control unit 140 measures the drive current waveform and compares the measured waveform rise time or peak current with a pre-learned normal pattern to predict fault symptoms.

[0037] Beneficial effects As described above, the present invention has the following effects.

[0038] First, the composite communication control smart valve 10 according to the present invention simultaneously possesses an IoT communication unit 147 and an RF communication unit 148, and monitors the communication status in real time. When no response is received from a remote server within a preset time, it automatically switches (Fail-over) to the RF-based local control mode. Thus, even in the event of network failure, server downtime, or internet instability, the valve drive unit 120 can be instantly driven to perform a closing action via the wireless leak detector 200 and the RF remote controller 300. Therefore, it achieves the effect of stably maintaining the core safety function of leak shut-off regardless of the status of the communication infrastructure.

[0039] Secondly, the present invention employs a multi-level power supply system consisting of a valve drive unit 120 with a latching solenoid valve structure, a main power supply unit 150, an emergency power supply unit 152, and an external emergency power connector. Under normal conditions, power consumption can be minimized, and in the event of a power outage, only a small amount of power stored in the emergency power supply unit 152 is needed to reliably complete at least one "closing" operation. Furthermore, even when the emergency power supply unit 152 is completely discharged, temporary valve actuation can be achieved by connecting an external battery pack or the like to the emergency power connector, thus ensuring the valve's shut-off function remains intact even under prolonged power outages or sudden power failures.

[0040] Third, the present invention provides a ball valve structure comprising a valve ball 107 and a manual operation unit 115 arranged in parallel within the flow path 101 of the valve body 100. This allows the user to forcibly open or close the flow path 101 even in the worst-case scenario where all electronic and electrical systems, such as the valve control unit 140 and the valve drive unit 120, fail. This enables the user to use simple tools such as a flathead screwdriver or wrench to rotate the valve ball 107 90 degrees. Thus, even in the event of a complete system failure, the essential function of fluid shut-off can still be guaranteed, providing a mechanical fail-safe effect.

[0041] Fourth, the push-fit pipe connector according to the present invention comprises a ferrule 105, an O-ring 102, an O-ring 109, an insertion ring 103, a spacer 110, a cap 104, and a scraping lip 105-1 disposed inside the cap. No additional threading or welding is required; a secure fixation and seal are achieved simply by inserting the pipe. In particular, the scraping lip 105-1 scrapes away dirt, dust, oil, rust, and other foreign matter from the pipe surface upon insertion, preventing foreign matter from entering the area around the O-ring 102 at the source. This significantly reduces the probability of leakage and seal failure during long-term use and minimizes variations in construction quality. Therefore, even non-professional pipe technicians, general users, or equipment maintenance personnel can quickly and accurately complete installation and disassembly without tools, greatly saving installation time and costs.

[0042] Fifth, by installing a mesh filter 111 on the flow path inlet side of the valve body 100, this invention can prevent sand, rust, and other particulate foreign objects remaining inside the pipeline from entering the diaphragm 121 and valve drive unit 120 after construction. This fundamentally reduces the causes of failures such as damage to the sealing surface, obstruction of the plunger 124 movement, and valve jamming, improving the durability and long-term reliability of the entire valve system. Furthermore, the mesh filter 111 can be designed as a detachable structure to improve maintenance efficiency through regular cleaning or replacement.

[0043] Sixth, the valve drive unit 120 of the present invention adopts a latching solenoid valve structure and realizes the opening and closing of the flow path 101 through the diaphragm 121. It only uses short-time pulse power during state switching and does not consume power during state maintenance. Therefore, even when the external main power supply unit 150 is continuously powered, its standby power consumption is extremely low, and it has excellent energy efficiency. At the same time, the most basic cut-off action can be completed by relying solely on the emergency power supply unit 152 without repeatedly consuming power to maintain the state. In addition, since the diaphragm 121 completely isolates the wet part and the dry part, it can effectively reduce the risk of leakage and corrosion, and can still ensure stable and reliable opening and closing response characteristics in high pressure or rapidly changing pressure environments.

[0044] Seventh, this invention, by incorporating a multi-layered waterproof structure in the wireless water leak detector 200, including an outer O-ring 204, a battery seal 202, a side ring, and a waterproof mesh 210, combined with an ultra-low power consumption circuit design, enables it to operate stably for extended periods in high-humidity or splash-prone environments such as under sinks, boiler rooms, and laundry rooms without malfunctioning. Furthermore, the sensing rod 206 is designed to accurately detect leaks even in shallow water conditions, allowing for early detection of minor leaks while significantly extending battery life and reducing maintenance and replacement frequency.

[0045] Eighth, in the valve control unit 140 of the present invention, the processor 145, when driving the valve drive unit 120, samples the current waveform flowing through the coil body 131 in real time, and compares and analyzes the collected parameters such as rise time and peak current with pre-stored normal modes and AI algorithms, thereby enabling early prediction of fault symptoms caused by factors such as scale accumulation, increased friction, and O-ring aging and hardening. When a fault symptom is detected, preventive maintenance reminders can be provided to the user through the IoT communication unit 147; and when the peak current exceeds the danger threshold, the power supply to the valve drive unit 120 can be immediately cut off to prevent sudden equipment failure and secondary damage caused therefrom, thereby effectively reducing maintenance costs and system downtime.

[0046] Ninth, the composite communication control smart valve according to the present invention can be linked with a cloud server through the IoT communication unit 147 to periodically upload information such as the valve's open / closed status, leakage history, remaining battery power of the emergency power unit 152, communication status, and fault prediction results to the server. Users can view this information in real time through terminal devices such as smartphone applications. Furthermore, the firmware can be remotely upgraded using OTA (Over-The-Air) technology, allowing for continuous application of algorithm optimization, new feature expansion, and security patches after installation. Therefore, the present invention is not limited to applications with a single device, but can be extended to a smart water and gas control system at the level of smart homes, smart buildings, and urban infrastructure for centralized management of multiple valves and sensors.

[0047] Tenth, the present invention can also achieve the following automatic diagnostic functions by further integrating flow sensors or pressure sensors into the valve body 100: for example, if a small flow is detected when the valve is in the "closed" state, it can be determined that the seal is not good; if a flow is continuously detected during periods when there should theoretically be no flow, such as at night or in an out-of-town mode, it can be automatically identified as a hidden leak. By comprehensively analyzing flow / pressure data, leak detection signals, and AI fault prediction results, all-weather monitoring of the entire pipeline system and proactive shut-off and early warning can be achieved without continuous manual monitoring.

[0048] Eleventh, the intelligent valve system of this invention can be equipped with energy harvesting devices such as micro-hydrogen generators in the flow path 101 as needed, converting fluid flow into electrical energy. This enables quasi-permanent operation without external power supply in buried pipelines, remote agricultural irrigation systems, and pipeline environments in mountainous and island areas where main power is difficult to introduce. Consequently, it can significantly reduce additional power supply construction costs and battery replacement costs, and realize an energy-self-sufficient intelligent valve system in various application scenarios.

[0049] Twelfth, the composite communication control smart valve according to the present invention can support Wi-Fi, LTE, NB-IoT, and LoRaWAN, and is also compatible with multiple standard communication protocols such as Matter, Thread, Zigbee, Z-Wave, and BLE Mesh. Therefore, it is not limited to specific manufacturer platforms and can be organically linked with Apple Home Kit, Google Home, Samsung SmartThings, and building automation systems (BAS / BMS). Thus, users can easily integrate the valve of the present invention into various automation scenarios such as "away mode," "sleep mode," and "fire alarm mode," working in conjunction with lighting, heating, and security systems to achieve a higher level of security and convenience.

Detailed Implementation

[0057] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0058] The core idea of ​​this invention is to ensure that even in any emergency situation, such as network outages, power failures, or system malfunctions, the core safety function of shutting off fluids, especially leaks, can be consistently executed. To this end, this invention organically combines dual communication paths, dual power supply systems, and multi-level fail-safe measures with artificial intelligence technology.

[0059] The dual communication paths include an IoT communication unit 147 and an RF communication unit 148, and the dual power supply system includes a main power supply unit 150, an emergency power supply unit 152, and an external emergency power connector.

[0060] Reference Figures 1 to 4 According to an embodiment of the present invention, a composite communication control smart valve 10 includes: a valve body 100 forming a flow path 101 for fluid to pass through and supporting a valve mechanical structure; a valve driving unit 120 for opening or closing the flow path 101 of the valve body 100 via a diaphragm 121; and a valve control unit 140 for intelligently controlling the operation of the valve driving unit 120.

[0061] According to an embodiment of the present invention, the composite communication control smart valve 10 includes: a valve body 100 having a flow path 101 for fluid flow; a valve drive unit 120 coupled to the valve body 100 and opening or closing the flow path 101; and a valve control unit 140 for controlling the valve drive unit 120, including an IoT communication unit 147 for communicating with a remote server and an RF communication unit 148 for communicating with near-field devices 200 and 300.

[0062] The valve control unit 140 includes: a non-volatile memory 146 for storing instructions; and a processor 145 connected to execute the instructions.

[0063] The processor 145 is configured to: monitor the communication status with the remote server; when no response is received from the remote server within a preset time, automatically switch the control mode from the IoT communication-based control mode to the RF communication-based local control mode; and when a leak detection signal is received from the wireless leak detector 200 through the RF communication unit 148, treat the signal as a high-priority interrupt and immediately drive the valve drive unit 120 to perform a shut-off action.

[0064] The following will describe the pipeline connection structure of the valve body 100 and its push-fit connection structure.

[0065] In a composite communication control smart valve 10 according to an embodiment of the present invention, the valve body 100 serves as the basic main body of the smart valve and is used to provide a flow path 101 connecting the inlet side and the outlet side.

[0066] In this embodiment, the valve body 100 can be manufactured by injection molding using engineering plastic materials such as polyoxymethylene (ACETAL, POM).

[0067] Polyoxymethylene resin has excellent mechanical strength and wear resistance, low water absorption, and is not easily adhered to by scale or foreign matter in water, making it very suitable as a valve material for long-term use in water pipe systems.

[0068] Of course, depending on the usage environment and the type of fluid, the valve body 100 can also be made of metal materials such as brass or stainless steel.

[0069] The internal flow path 101 of the valve body 100 is configured to accommodate a diaphragm 121, a ball valve 107, and other shut-off mechanisms, and can be designed as a straight or curved structure according to the flow characteristics of the fluid.

[0070] At both ends of the valve body 100, there are pipe connection ports for easy connection of the pipes or pipe materials to the following push-fit connection structures.

[0071] This structure requires no additional threading or welding; it achieves fixation and sealing simply by inserting the pipe, thus greatly improving construction convenience.

[0072] like Figure 2 and Figure 3 As shown, the pipe connection port of the push-in connection structure may include: a ferrule 105 for clamping the outer periphery of the pipe; an O-ring 102 for sealing the gap between the pipe and the valve body 100; a cap 104 for supporting and protecting the ferrule 105 and the O-ring 102; a support SPO ring 109 for preventing deformation of the front end of the O-ring 102; a spacer 110 for limiting the pipe insertion depth and preventing interference with adjacent components; and an insertion ring 103 for supporting the pipe end and enhancing the overall structural rigidity, etc.

[0073] First, the ferrule 105 is an annular component with sharp, serrated teeth on its inner circumferential surface. When the user pushes the pipe into the pipe connection port of the valve body 100, the teeth of the ferrule 105 will firmly engage with the outer circumferential surface of the pipe, thereby preventing the pipe from coming out backward.

[0074] The clamping sleeve 105 can be made of elastic metal or hard resin material. While firmly clamping the pipe, the clamping force of the sleeve can be released when the user presses the cover 104 towards the valve body. Thus, the clamping sleeve 105 functions as a core component in a structure that can be disassembled and assembled without tools.

[0075] Furthermore, an O-ring 102 is provided between the pipe and the valve body 100 to prevent fluid inside the flow path 101 from leaking to the outside, thereby achieving a reliable seal.

[0076] The O-ring 102 can be made of a synthetic rubber material with excellent water resistance and pressure resistance, such as EPDM.

[0077] In this embodiment, an SPO ring 109 made of a relatively high-hardness material is disposed at the rear end of the O-ring 102. It is used as a backup ring to prevent the O-ring 102 from shifting backward or deforming excessively under water pressure.

[0078] In addition, a spacer 110 is provided between the O-ring 102 and the adjacent ball valve 107 or other components to prevent direct contact or interference between the O-ring and other components.

[0079] The spacer 110 also acts as a stop, allowing the pipe to remain in a predetermined position when fully inserted, thus ensuring a consistent insertion depth during each installation and reducing installation deviations.

[0080] Meanwhile, the insertion ring 103 is pressed into the inner end of the valve body 100 to support the pipe end and prevent the pipe end from deforming under water pressure or external force, thereby improving the durability of the entire connection structure.

[0081] The cover 104 is an annular component, which is fixed to the end of the valve body 100 by means of threaded connection or other means. It houses the ferrule 105, O-ring 102 and other components, and provides positioning support for the above components, so that they are stably placed in the predetermined position.

[0082] In addition, the cover 104 is configured to be pressable from the outside toward the valve body 100. When the cover is pressed, it pushes the ferrule 105, causing the teeth of the ferrule to disengage from the pipe, thereby releasing the pipe from its fixation and achieving a tool-free disassembly structure.

[0083] Therefore, when performing maintenance, users do not need to use wrenches or other special tools; they can easily disassemble the pipe simply by pressing the cover 104 with their hands.

[0084] An important feature of the present invention is a scraping lip 105-1 disposed on the inner side of the cover 104.

[0085] The scraping lip 105-1 is a thin lip-shaped structure made of elastic materials such as rubber, extending obliquely in the opposite direction to the insertion direction of the pipe, and in close contact with the outer circumferential surface of the pipe.

[0086] When a pipe containing contaminants is inserted, the scraping lip 105-1 will adhere tightly to the pipe surface and scrape away surface contaminants, expelling dirt, dust, oil, rust, etc. to the outside, thereby preventing these foreign objects from entering the area around the O-ring seal 102.

[0087] This structure effectively reduces wear and damage to the O-ring 102, thereby significantly reducing the risk of leakage and improving the valve's durability during long-term use.

[0088] The scraping lip 105-1 can be integrally formed with the cover 104, or formed on a separate annular component and then inserted into the cover 104.

[0089] The following describes the structure of the mesh filter 111 used to block foreign objects.

[0090] Reference Figure 2 The inlet side of the flow path 101 of the valve body 100 may be arranged with a mesh filter 111 made of dense metal mesh such as stainless steel (SUS304).

[0091] After pipeline construction, sand, rust flakes from old pipelines, or other foreign objects may remain inside the pipeline. If these foreign objects enter the valve body, they will not only reduce the sealing performance of the valve drive unit 120 and the diaphragm 121, but are also one of the main causes of valve failure.

[0092] The mesh filter 111 can selectively filter out particulate impurities at the front end of the flow path, thereby preventing foreign objects from entering the valve drive section 120 and the cut-off section in advance.

[0093] The mesh filter 111 can be designed as a detachable structure for regular cleaning or replacement. This filter structure plays a key protective role in ensuring the overall durability and long-term reliability of the valve system.

[0094] The following describes one embodiment of the valve drive unit 120, which employs a latching solenoid structure and a diaphragm 121 cut-off method.

[0095] First, refer to Figure 3 and Figure 5 The valve drive unit 120 can adopt a pull-type electromagnet structure to realize the function of an electric valve driver.

[0096] The valve drive unit 120 includes a coil body 131 that generates electromagnetic force, a liner 124 that reciprocates along the central channel of the coil, a guide valve core 125 for guiding the linear movement of the liner 124, a permanent magnet 127 disposed at or around the lower end of the liner 124 for fixing the liner 124 by magnetic force, a cover plate 126 that forms a magnetic circuit and protects the internal components, an O-ring 129 for sealing and buffering and its fixing clamp 130, a support member 122 for transmitting pressure between the liner 124 and the diaphragm 121, and a liner cover 123 that is combined with the front end of the liner 124.

[0097] The pull electromagnet adopts a bistable structure, which has two stable states: "on" and "off".

[0098] The valve control unit 140 switches the position of the liner 124 only when a short pulse current is applied to the coil body 131, and even after the power is turned off, the state of the liner 124 is still maintained by the magnetic force of the permanent magnet 127.

[0099] For example, to switch the valve from the closed state to the open state, the valve control unit 140 applies a positive pulse current (e.g., +12V) to the coil body 131 for tens of milliseconds (ms). At this time, the electromagnetic force generated by the coil body 131 interacts with the magnetic force of the permanent magnet 127, causing the liner 124 to move to the lower "open" position.

[0100] When the liner 124 reaches this position, the current is cut off, but the liner 124 is still held in this position by the magnetic force of the permanent magnet 127.

[0101] Conversely, when switching from the "on" state to the "off" state, a reverse pulse current (e.g., -12V) is applied to move the liner 124 to the upper or opposite position, and then it is held in that position again by magnetic force.

[0102] This structure consumes no power while maintaining its state, and only consumes power momentarily when switching states, thus it is very energy efficient.

[0103] Thus, the pull valve drive unit 120 of the present invention can complete at least one reliable shut-off action in the event of a power failure using a low-capacity battery such as the emergency power supply unit 152, becoming a core component of power fail-safe protection.

[0104] In addition, a spring 128 is provided on the outer periphery of the liner 124 to provide appropriate elastic force during the movement of the liner 124, or to assist the liner 124 in returning to its initial position.

[0105] The structure of diaphragm 121 and the wet / dry zone separation structure will be described next. A diaphragm 121 in the form of an elastic membrane is provided between the lower part of the valve drive unit 120 and the upper part of the valve body 100.

[0106] The diaphragm 121 may be made of synthetic rubber, such as EPDM, which has excellent resistance to fluids, and is fitted to a seat disposed in the flow path 101 to completely block the flow of fluid.

[0107] When the lining 124 moves downward, pressure is applied to the diaphragm 121 through the lining cover 123 and the support member 122 at the lower end of the lining 124, so that the flow path 101 is closed. When the lining 124 moves in the opposite direction, the diaphragm 121 returns to its original state, so that the flow path 101 is opened.

[0108] The diaphragm 121 provides an internal partition structure that completely isolates the lower wet part through which the fluid flows from the upper dry part where the coil, power circuit, telecommunications module, etc. are located, thereby effectively preventing leakage, electric shock, corrosion, etc. caused by the fluid.

[0109] In addition, when the lining 124 is activated, the diaphragm 121 can expand or contract slightly with changes in internal pressure, thereby suppressing the formation of back pressure and improving the valve response speed, thus achieving a pressure balance function.

[0110] The following describes the fixing structure of the valve drive unit 120, including the housing 112, the bracket 132, and the bolt 142.

[0111] like Figure 3 As shown, the valve drive unit 120 is securely mounted inside the housing 112 on the upper part of the valve.

[0112] The valve drive unit 120 is installed after the valve body 100, and an internal metal bracket 132 is provided above it.

[0113] The internal support 132 is a U-shaped support plate used to press the upper end of the coil body 131. A flange 132a is formed on its upper part, and a through screw hole 132b is provided on the flange for inserting bolts 142.

[0114] Bolt 142 engages with the boss formed on the housing 112 to firmly fix the bracket 132, and at the same time cooperates with the stop 125a formed on the upper surface of the guide valve core 125 to keep the position of the coil body 131 stable and not shake.

[0115] With the above-mentioned fixing structure, the valve drive unit 120 can still be firmly fixed under the conditions of fluid pressure change, external impact and vibration, ensuring that the power transmission between the lining iron 124 and the diaphragm 121 is always accurate and reliable.

[0116] This structure not only facilitates the production and assembly process, but also makes future maintenance operations, which only require replacing the valve drive module 120, much simpler.

[0117] The bolt 142 may be treated with anti-loosening agents, such as by coating it with thread-locking agent, to prevent vibration from causing it to loosen.

[0118] The upper end of the valve body 100 is provided with a stepped shoulder 100a and an annular support portion 100c with a screw hole 100b.

[0119] The stepped shoulder 100a supports the lower end 112a of the housing 112 and keeps its position stable. The upper end of the annular support 100c supports the lower end of the guide valve core 125, and the guide valve core 125 is securely fixed inside the housing 112 by the bolt 142 through the screw hole 100b. In addition, the diaphragm 121 and the support member 122 can also be stably installed inside the annular support 100c.

[0120] The hybrid communication structure and power failure protection technology of the valve control unit 140 will be explained below.

[0121] Reference Figure 3 and Figure 4 The basic structure of the valve control unit 140 is as follows: the valve control unit 140 is arranged in the upper space of the housing 112 in the form of a PCB printed circuit board.

[0122] The valve control unit 140 is sealed by a cover plate 141 covering the opening at the top of the housing, and the cover plate 141 is firmly fixed to the housing 112 by a plurality of housing bolts 143.

[0123] The valve control unit 140 includes: a processor 145 for controlling the entire operation of the smart valve; a memory 146 for storing firmware and various log data; an IoT communication unit 147 for communicating with a remote server via the Internet; an RF communication unit 148 for short-range communication with a wireless leak sensor 200 and an RF remote controller 300; a power management circuit for managing the main power supply 150 and the emergency power supply 152; and a drive circuit, such as an H-bridge, for applying pulse power to the valve drive unit 120.

[0124] The processor 145 can be implemented as a microcontroller (MCU) or a system-on-a-chip (SoC), and the non-volatile memory 146 can be of the type Flash or EEPROM.

[0125] Regarding hybrid communication, namely the IoT communication unit 147 + RF communication unit 148 technology, the valve control unit 140 differs from existing IoT valves by adopting a hybrid communication architecture that simultaneously possesses two heterogeneous communication paths.

[0126] The IoT communication unit 147 communicates bidirectionally with a remote server cloud via wireless communication methods such as Wi-Fi, LTE, NB-IoT, and LoRaWAN, enabling functions such as remote on / off control, status monitoring, and firmware OTA (Over-the-Air) updates via a smartphone application.

[0127] The RF communication unit 148 includes a short-range RF transceiver that operates in the 433MHz or 900MHz frequency band, and can communicate directly with the wireless water leakage sensor 200, the RF remote controller 300 and terminal equipment. Even when the Internet is disconnected, it can stably control the valve in the local environment.

[0128] Normally, the processor 145 exchanges heartbeat signals with the remote server periodically through the IoT communication unit 147 to monitor the communication status.

[0129] If no response is received from the server within a preset time (e.g., 3 minutes or 5 minutes), the processor 145 will recognize it as a communication interruption state and automatically switch the control mode from the IoT-based control mode (Fail-over) to the RF-based local control mode.

[0130] At this time, the processor 145 will stop or minimize the driving of the power-consuming IoT communication unit 147, and only maintain the local control system with the RF communication unit 148 as the core, so that even in the event of a communication failure, the necessary safety functions can be maintained with minimal power consumption.

[0131] Upon receiving an RF emergency signal from the wireless leak sensor 200, the processor 145 treats it as a high-priority interrupt, unaffected by ongoing communications, log uploads, or other tasks, and immediately applies a "close" pulse signal to the valve actuator 120. In this way, valve closing delays caused by network latency or server failures can be fundamentally avoided, minimizing leak damage.

[0132] Regarding the power system and power failure protection technology, the main power supply unit 150 is provided in the form of a DC adapter that converts external AC power to DC power, and supplies power to the valve control unit 140, the valve drive unit 120 and the IoT communication unit 147.

[0133] The power management circuit monitors the main power supply voltage in real time and distributes a stable voltage to each circuit.

[0134] In response to power outages, the emergency power supply unit 152 can be configured via a removable battery holder on the valve control unit 140 PCB, for example, by using two CR2450 lithium button batteries.

[0135] The MCU uses its internal ADC to monitor the emergency battery voltage in real time. When the battery is low, it sends a replacement reminder to the user's smartphone app via the IoT communication unit 147.

[0136] Once a power outage is detected, the power management circuit first cuts off power-intensive modules such as the IoT communication unit 147 and switches the processor 145 to "Deep Sleep" mode, waiting only to receive emergency signals via the RF communication unit 148. In this state, when an RF emergency signal is received from the wireless water leak sensor 200, the processor 145 immediately starts up, obtains power from the emergency power supply unit 152 for a specified period of time, applies one or more "shutdown" pulses to the valve drive unit 120, and then returns to sleep mode.

[0137] like Figure 1 and Figure 4 As shown, an external emergency power connector can be located on the outside of housing 112 for connecting an external emergency power pack (e.g., a temporary power supply consisting of 4 AA batteries).

[0138] Even in extreme cases where a prolonged power outage depletes the emergency power supply unit 152, the user can still temporarily drive the valve drive unit 120 by connecting a simple battery pack and operating it manually via button 113 or through automatic control.

[0139] In addition, a storage hook 154 may be provided on the cable of the housing 112 or the main power unit 150. The storage hook 154 can be used to organize excess wires or adapters, or to hang the RF remote controller 300.

[0140] The following describes the AI-based self-diagnosis and fault prediction functions.

[0141] When the valve control unit 140 drives the valve drive unit 120, the processor 145 samples the drive current flowing through the coil body 131 in real time, generates a current waveform, and compares and analyzes its characteristic values ​​such as rise time and peak current with the pre-stored normal mode to predict fault symptoms.

[0142] When the valve is working normally, the current shows a constant rising curve and peak point. However, when scale or foreign matter accumulates inside the valve, or when there is insufficient lubrication or increased mechanical friction, the movement of plunger 124 will be delayed, resulting in a prolonged rise time of the current waveform or an abnormal increase in peak current.

[0143] The non-volatile memory 146 stores current waveform data corresponding to normal state and various fault types, and can be equipped with AI algorithms based on machine learning or deep learning when necessary.

[0144] Each time the processor 145 is driven, it uses the algorithm to analyze and measure the waveform. When the rise time exceeds the set threshold (e.g., 20ms) or the peak current exceeds the allowable range (e.g., 600mA), it is judged as a fault sign and a preventive maintenance reminder is sent to the user's smartphone App and remote server through the IoT communication unit 147.

[0145] When the peak current exceeds the danger level, the power supply to the valve drive unit 120 can be immediately cut off for safety reasons.

[0146] This self-diagnosis and fault prediction function can perform preventive inspections and maintenance before the valve is completely stuck. When necessary, the training and updating of the AI ​​model can be continuously optimized and upgraded through cloud servers (remote servers) combined with big data analysis.

[0147] The following describes the structure and waterproof design of the wireless water leakage sensor 200.

[0148] See Figure 3 and Figure 6 In addition to the valve body 100, the intelligent valve system 10 of the present invention also includes a proximity device 200 that communicates via RF.

[0149] The wireless leak sensor can register multiple devices and emit sounds at multiple leak locations to confirm the specific leak site.

[0150] The wireless water leakage sensor 200 can be placed under the kitchen sink, on the floor of the laundry room, in the boiler room, or other locations with a high risk of water leakage. By detecting water accumulation on the ground, it sends an RF emergency signal to the valve control unit 140.

[0151] The wireless water leakage sensor 200 may include a lower shell 201 and an upper shell 209, an O-ring 204 sealing the joint between the lower shell and the upper shell, a battery seal 202 sealing the joint between the battery cover 203, a side ring 205 for lateral impact absorption and waterproof enhancement, a sensing rod 206 extending through the bottom of the lower shell and protruding outwards, a sensing control circuit 207 for processing sensing signals, a cover fixing bolt 208, and a waterproof mesh 210 installed through a vent hole, etc.

[0152] The bottom surface of the lower shell 201 has one or more pairs of metal sensing rods 206 protruding in pairs, which are normally insulated from each other by air.

[0153] When water accumulates on the ground and both sensor rods are simultaneously submerged, water acts as a conductive medium, and the sensing control circuit 207 determines that a water leak has occurred.

[0154] The sensing control circuit 207 may consist of a low-power microcontroller, a battery, and an RF communication module. When a leak is detected, the built-in RF module immediately sends an emergency RF signal to a pre-registered receiving target, namely the valve control unit 140.

[0155] To adapt to long-term humid environments, the wireless water leakage sensor 200 adopts a multi-layer waterproof structure.

[0156] An O-ring 204 is embedded at the junction of the lower shell 201 and the upper shell 209 to prevent water from entering the internal PCB. An independent battery seal 202 is provided at the junction of the battery cover 203 to ensure that the waterproof performance is maintained after the battery is replaced.

[0157] Side ring 205 is embedded on the outside of the cap mating surface to cushion external impacts and enhance lateral waterproofing.

[0158] In addition, the upper shell 209 may be provided with a micro vent for the sound of the built-in buzzer and the discharge of internal water vapor. The vent is fitted with a waterproof mesh 210, such as Gore-Tex material, which allows air to pass through but prevents water droplets from entering.

[0159] The wireless water leakage sensor 200 is powered by a built-in button battery (such as two CR24503V batteries or one 6V battery), which can achieve an ultra-long battery life of several years or even more than 10 years by limiting the standby current to below a few μA.

[0160] When the battery is low, the sensing control circuit 207 can send a battery replacement reminder to the valve control unit 140, or issue a warning to the user by flashing its own LED. If necessary, specific design parameters such as sensing height, electrode shape, and waterproof rating of IP67 or higher can be adjusted.

[0161] The following describes the local remote control function of the RF remote controller 300.

[0162] See Figure 3 The RF Remote 300 is a portable proximity device for users to manually control valves at close range.

[0163] The RF remote controller 300 includes a PCB 303, a battery, and an "ON" button 304 and an "OFF" button 305 inside a small housing. When the user operates the buttons 304 and 305, an RF signal corresponding to the action is generated and sent to the RF communication unit 148 of the valve control unit 140.

[0164] The RF remote control 300 can be operated without the need for the internet or a smartphone app, so it can still reliably control valves even in the event of Wi-Fi interruption or server failure, making it an important auxiliary control method.

[0165] In addition, for users who are not familiar with smartphone operation, or who do not have a smartphone with them, they can still open and close the valve through intuitive button operation, which improves the ease of use.

[0166] The remote control 300 is powered by a small battery and, through its low-power design, can be used for many years. If necessary, a wall hook 154 can be provided for secure management of the remote control and to prevent loss.

[0167] The manual shut-off function, implemented via mechanical fail-safe and ball valve 107, is described below. To address the worst-case scenario of complete failure of both the electronic and electrical systems, this invention provides an additional mechanical fail-safe mechanism.

[0168] See Figure 2 and Figure 3 A ball valve structure is provided on one side flow path 101 of valve body 100.

[0169] The sphere 107 may be made of materials such as brass or stainless steel and has a through hole 107a.

[0170] A pair of guide rings 106 supporting the sphere are provided on both sides of the sphere 107. A ball O-ring 108 is provided on the contact surface between the sphere 107 and the ball guide ring 106 to reduce rotational friction, prevent micro-leakage and enhance sealing.

[0171] The sphere 107 can rotate about 90 degrees under external force. When the sphere hole 107a is aligned with the flow path 101, it is in the "open" state, and when it is perpendicular to the flow path, it is in the "closed" state.

[0172] The valve body 100 may be provided with a groove or slot-shaped manual operation part 115 on the outside, into which a flathead screwdriver or an Allen wrench can be inserted. The manual operation part 115 is mechanically connected to the ball 107.

[0173] In this embodiment, the manual operation unit 115 refers to a mechanical manual operation means that drives the ball valve through a tool, while the aforementioned manual button 113 is an electrical manual button used for pressing in an emergency.

[0174] Therefore, even if the valve control unit 140 is damaged due to fire, or the valve drive unit 120 cannot be operated electrically due to coil breakage or mechanical jamming, the user can still force the flow path 101 to open or close by inserting a tool into the manual operation unit 115 and rotating the ball 107.

[0175] Even if all electronic and electrical systems fail, this ensures that the valve's essential function of cutting off fluid remains intact, thus providing ultimate safety.

[0176] The following describes the control method of the composite communication control smart valve of the present invention.

[0177] The control method of the composite communication control smart valve of the present invention includes the following steps: the valve control unit 140 periodically monitors the communication status with the remote server through the IoT communication unit 147; when the valve control unit 140 detects that no response is received from the remote server within a preset time and identifies it as a communication interruption state, it switches the control mode from the IoT communication unit 147 to the local control mode (Fail-over) using the RF communication unit 148; when a leakage detection signal is received from the nearby devices 200 and 300 through the RF communication unit 148, the valve control unit 140 interrupts the currently executed operation and drives the valve drive unit 120 to perform a closing action with the highest priority.

[0178] The control method of the composite communication control smart valve according to the present invention further includes the following steps: during the operation of the valve drive unit 120, the valve control unit 140 measures the drive current waveform and compares the rise time or peak current of the measured waveform with a pre-learned normal pattern to predict fault signs.

[0179] The control method for the composite communication control smart valve according to the present invention can be implemented according to the following steps: Communication status monitoring steps The processor 145 of the valve control unit 140 periodically exchanges heartbeat signals with a remote server via the IoT communication unit 147 to monitor the communication status.

[0180] Communication interruption detection and failover steps If no response is received from the server within the predetermined time, the processor 145 detects a communication interruption and automatically switches the control mode from the IoT-based remote control mode to the local control mode utilizing the RF communication unit 148. At this time, the processor 145 stops or minimizes the operation of the IoT communication unit 147, maintaining only the local control system centered on the RF communication unit 148, thereby maintaining stable control even in the event of communication abnormalities.

[0181] Highest priority shutdown procedure for RF emergency signals When a leak detection signal or emergency shutdown command is received from the wireless leak sensor 200 or the RF remote controller 300 via the RF communication unit 148, the processor 145 immediately interrupts all currently executed operations such as server communication, log uploading, and routine control, and processes the interruption with the highest priority, sending a shutdown pulse signal to the valve drive unit 120.

[0182] Deep Sleep and Emergency Power Linkage Procedures in Case of Power Failure The valve control unit 140 monitors the voltage of the main power supply 150. When a power outage is detected, it shuts down power-consuming modules such as the IoT communication unit 147 and switches the processor 145 to a deep sleep mode, waiting only to receive an emergency signal through the RF communication unit 148. If a water leakage detection signal is received during the power outage, the processor 145 uses the emergency power supply 152 to power the valve drive unit 120 to perform a closing action at least once before returning to the low-power mode.

[0183] Fault prediction steps using current waveform analysis During the operation of the valve actuation unit 120, the valve control unit 140 samples the drive current flowing through the coil body 131, generates a current waveform, and compares the rise time and peak current of this waveform with a pre-learned normal pattern. If the current waveform shows an abnormal pattern (e.g., prolonged rise time, excessive peak current), the processor 145 generates a fault diagnosis signal and records it in the memory 146, while simultaneously sending a preventative maintenance notification to the remote server and user terminal via the IoT communication unit 147. When the peak current exceeds a dangerous level, the power supply to the valve actuation unit 120 can be immediately cut off to perform a protective action.

[0184] Through the above control method, the composite communication control smart valve of the present invention can still achieve the core safety function of water leakage cut-off through the hierarchical fault protection structure even in various emergency situations such as communication interruption, power failure or mechanical failure. Furthermore, each control step and algorithm can be further described or expanded in detail as needed.

[0185] Furthermore, the present invention can provide an intelligent valve system that can automatically shut off fluid leakage even in the event of network failure or power outage. The system includes a valve body 100 and a leakage sensor that can communicate wirelessly.

[0186] The present invention may also include a flow sensor attached to the valve body 100, wherein the valve control unit 140 detects fluid flow through the flow sensor when the valve is in the closed state, and determines that a leak has occurred, thus forming a composite communication control smart valve.

[0187] Furthermore, the present invention may include a detection device for detecting leaks and transmitting wireless signals. The detection device includes a waterproof housing consisting of an upper housing 209 and a lower housing 201, a leak detection sensor and an ultra-low power circuit 207 arranged inside the housing, and multiple sealing means (such as a battery seal 202, a cover O-ring 204, a side ring 205, a waterproof mesh 210, etc.) for sealing gaps in the housing.

[0188] The smart valve of the present invention may include a valve body 100 having a fluid flow path 101; a valve drive unit 120 for opening or closing the flow path; and a valve control unit 140 for controlling the valve drive unit, continuously monitoring the communication availability status, and sending and receiving control signals through a second communication path when the first communication path fails.

[0189] It should be understood that the specific structural or functional descriptions involved in the embodiments of the present invention disclosed in this specification are only for illustrating the embodiments of the present invention and are not intended to limit the embodiments of the present invention. Embodiments of the present invention can take many forms, and the embodiments described in this specification should not be construed as limiting the present invention.
