[0002] With the acceleration of urbanization and the improvement of people's living standards, the requirements for heating systems are getting higher and higher. In traditional heating systems, the second network (i.e., the secondary heating network) is the key link connecting the heat source and the user. Due to the complex terrain and uneven distribution of users, there are often problems of hydraulic imbalance and thermal imbalance in the second network, resulting in uneven indoor temperature and increased energy consumption of users. In order to solve these problems, it is necessary to use a balanced adjustment of the second network. At present, the traditional valve power connection methods include connecting to the mains or using batteries for power supply.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0028] The method embodiments provided in the embodiments of the present application can be executed in a valve control center, a computer terminal, a valve control center of a self-powered IoT valve, or a similar computing device. Taking running on a valve control center as an example, Figure 1 1 is a hardware structure block diagram of a valve control center of a self-powered IoT valve control method according to an embodiment of the present application. Figure 1 As shown, the valve control center may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a microprocessor or a processing device such as a programmable logic device (Field Programmable Gate Array, FPGA)) and a memory 104 for storing data, wherein the valve control center may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the valve control center. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0029] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the control method of the self-powered IoT valve in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method.

In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0031] In this embodiment, a control method for a self-powered IoT valve applied to a valve control center is provided, wherein the valve control center is connected to an energy storage module, and the energy storage module is used to store electric energy from a thermoelectric power generation module and release the electric energy to the valve control center. It should be noted that thermoelectric power generation refers to the principle of using thermoelectric materials to generate electric energy under temperature differences to provide power for IoT valves. The thermoelectric power generation module can generate electric energy using the temperature difference between the inside and outside of the pipeline. It has strong self-power supply capability and does not require an external power supply. Electric energy can be generated using the temperature difference of the pipeline. It reduces construction difficulty and cost, and does not require the laying of power grid cables, which reduces construction difficulty and cost.

[0032] Figure 2 is a flow chart of a control method for a self-powered IoT valve according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps:

[0033] Step S202: Acquire pipeline sensing parameters obtained by monitoring the heating pipeline, wherein the pipeline sensing parameters at least include the current pipeline temperature of the heating pipeline and the hot water flow rate in the heating pipeline;

[0034] Step S204: when it is determined that the current pipe temperature is inconsistent with the heating temperature set for the heating pipe in the preset control strategy, determining the regulating flow required to regulate the hot water flow according to the temperature difference between the current pipe temperature and the heating temperature;

[0035] Step S206: adjusting the valve opening based on the valve opening adjustment value corresponding to the regulated flow until the current pipeline temperature reaches the heating temperature.

[0036] Through the above steps, the pipeline sensing parameters obtained by monitoring the heating pipeline are obtained, wherein the pipeline sensing parameters at least include the current pipeline temperature of the heating pipeline and the hot water flow in the heating pipeline; when it is determined that the current pipeline temperature is inconsistent with the heating temperature set for the heating pipeline in the preset control strategy, the regulating flow required to adjust the hot water flow is determined according to the temperature difference between the current pipeline temperature and the heating temperature; the valve opening is adjusted based on the valve opening adjustment value corresponding to the regulating flow until the current pipeline temperature reaches the heating temperature. This application solves the problem of how to power the valve to control the normal operation of the valve by generating electricity using the temperature difference between the inside and outside of the pipeline, and realizes the self-powering of the IoT valve without the need for an external power supply, greatly reducing maintenance costs and installation complexity, thereby improving the precise control of the heating system, effectively improving energy utilization efficiency, and reducing energy waste.

[0037] Exemplarily, the control method of the self-powered IoT valve of the present application can be applied to various scenarios requiring precise temperature control in heating systems of residences, commercial buildings, industrial facilities, etc.

[0038] In an exemplary embodiment, the implementation process of determining the regulating flow required to adjust the hot water flow according to the temperature difference between the current pipe temperature and the heating temperature specifically includes: when it is determined that the current pipe temperature is lower than the heating temperature and the temperature difference is lower than a preset difference, calculating the water supply flow required to increase the current pipe temperature, and determining the water supply flow as the regulating flow. This precise flow regulation strategy helps to avoid over-regulation and under-regulation during the temperature regulation process, and improves the stability and comfort of the heating system.

[0039] Optionally, when it is determined that the current pipeline temperature is greater than the heating temperature and the temperature difference is less than a preset difference, the water supply flow rate required to lower the current pipeline temperature is calculated, and the water supply flow rate is determined as the regulating flow rate.

[0040] In an exemplary embodiment, the valve opening can also be adjusted based on the valve opening adjustment value corresponding to the regulated flow, specifically including: generating a valve control signal based on the valve opening adjustment value, and controlling the valve opening according to the valve control signal to increase the valve opening adjustment value on the current opening value, or controlling the valve opening according to the valve control signal to reduce the valve opening adjustment value on the current opening value. This control method can achieve fine-tuning of the valve opening, improve the response speed and control accuracy of the system, and can be applied to scenarios that require rapid response to temperature changes, such as rapid heating or cooling systems.

[0041] In an exemplary embodiment, after adjusting the valve opening based on the valve opening adjustment value corresponding to the regulated flow until the current pipe temperature reaches the heating temperature, the current pipe temperature of the heating pipe, the hot water flow in the heating pipe and the valve opening of the heating pipe are further synchronized to the cloud server, so that the cloud server adjusts the control strategy for other self-powered IoT valves according to the current pipe temperature of the heating pipe, the hot water flow in the heating pipe and the valve opening of the heating pipe. This embodiment can achieve optimized control of the entire heating system through centralized management of the cloud server, improve the overall efficiency and stability of the system, and is suitable for large-scale building complexes or regional heating systems.

[0042] According to another aspect of the embodiment of the present application, a self-powered Internet of Things valve is also provided, including: an energy storage module, a valve control center and a temperature difference power generation module; the valve control center is connected to the energy storage module, the energy storage module is used to store the electric energy from the temperature difference power generation module, and release the electric energy to the valve control center; wherein the valve control center is also used to obtain the pipeline sensing parameters obtained by monitoring the heating pipeline, wherein the pipeline sensing parameters at least include the current pipeline temperature of the heating pipeline and the hot water flow in the heating pipeline; when it is determined that the current pipeline temperature is inconsistent with the heating temperature set for the heating pipeline in the preset control strategy, the regulating flow required to adjust the hot water flow is determined according to the temperature difference between the current pipeline temperature and the heating temperature; the valve opening is adjusted based on the valve opening adjustment value corresponding to the regulating flow until the current pipeline temperature reaches the heating temperature. The present application provides a self-powered Internet of Things valve used in a secondary network thermal well chamber, the core of which is to combine temperature difference power generation technology with Internet of Things technology to realize the intelligent control and self-powered function of the valve. Specifically, it monitors and adjusts the flow rate, temperature and other parameters in the pipe network in real time, realizes intelligent balance adjustment of the secondary pipe network, and improves the operating efficiency and stability of the heating system. This self-powered design not only reduces the dependence on traditional power sources and reduces installation and maintenance costs, but also improves the adaptability and flexibility of the system, and is suitable for heating system equipment that is difficult to wire or needs to be moved frequently.

[0043] In an exemplary embodiment, the thermoelectric power generation module includes at least: thermoelectric material, the thermoelectric power generation module is used to obtain the current generated by the thermoelectric material due to the temperature difference between the two ends, and generate the electric energy according to the current. The use of thermoelectric material enables the thermoelectric power generation module to obtain energy from the temperature difference of the heating pipe. This energy acquisition method has a natural advantage in the heating system and can achieve continuous operation of the system.

[0044] For example, bismuth telluride thermoelectric materials and multi-layer sheet heat sink structures can be used to improve the temperature difference power conversion efficiency and heat exchange performance, ensuring a stable and efficient power supply.

[0045] In an exemplary embodiment, the energy storage module at least includes: an energy storage battery, the energy storage module is used to store the electric energy using the energy storage battery, and release the electric energy stored in the energy storage battery to the valve control center. The use of the energy storage battery can supply power to the valve control center in time when the electric energy generated by the temperature difference power generation module is not enough to supply the valve control center immediately, thereby improving the stability and reliability of the system. For example, by using lithium-ion batteries, the high energy density and long life characteristics of lithium-ion batteries are utilized, so that the energy storage module can store electric energy for a long time, providing guarantee for the continuous operation of the valve.

[0046] In addition, the intelligent design of the IoT valve control module not only realizes the precise control and remote data transmission of the valve, but also has multiple functions such as data storage, low power consumption, multi-communication mode support, safety control, fault self-diagnosis, energy-saving mode and remote upgrade, which greatly improves the intelligence level and application flexibility of the valve. The use of waterproof design and quick-install interface enables the valve to work stably under various environmental conditions and is easy to install and replace quickly, further enhancing its adaptability and convenience in practical applications.

[0047] In summary, the IoT valve of the present application has achieved innovation in technical solutions and has significant practical value and broad application prospects.

[0048] Obviously, the embodiments described above are only some embodiments of the present application, not all embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0049] In an optional embodiment, key components of the valve such as Figure 3 shown.

[0050] The thermoelectric power generation module includes a heat sink (1), a thermoelectric material (2), a positive electrode (3), and a negative electrode (4). The thermoelectric power generation module utilizes the Seebeck effect of the thermoelectric material. When there is a temperature difference between the two ends of the thermoelectric material, an electric potential difference is generated inside the material, thereby driving the flow of electrons to form an electric current. After being collected by the electrodes, this current can charge the battery and thus power other components.

[0051] The energy storage module includes a battery (5). When the temperature difference power generation module generates electric energy, the electric energy will be stored in the energy storage module. The energy storage module will release the electric energy to maintain the normal operation of the IoT valve.

[0052] It can be seen that the thermoelectric material in the temperature difference power generation module uses the temperature difference between the inside and outside of the pipeline to generate electricity, and stores this electricity in the energy storage module. Through the coordinated work of the temperature difference power generation module and the energy storage module, the IoT valve realizes the self-powered function and reduces the dependence on external power supply. At the same time, the impact of environmental factors on the system is fully considered during the design process, and corresponding measures are taken to ensure the stable operation of the system.

[0053] The Internet of Things valve control module comprises a water supply temperature sensor (8), a return water temperature sensor (7), and an Internet of Things valve actuator (6) (corresponding to the above-mentioned valve control center) comprising a microprocessor, a communication module, an electric actuator, etc.

[0054] Among them, the temperature sensor is installed inside the pipeline to monitor the temperature of supply water and return water.

[0055] The microprocessor of the IoT valve actuator serves as the intelligent processing core, receiving sensor data, executing control algorithms, and outputting control signals.

[0056] The communication module is used for wireless transmission of data, which can be Wi-Fi, Bluetooth, LoRa, NB-IoT, etc.

[0057] The electric actuator adjusts the valve opening according to the control signal of the microprocessor.

[0058] The temperature sensor of the IoT valve control module monitors the temperature and other parameters in the pipeline in real time, and transmits these data to the microprocessor for processing. The microprocessor intelligently adjusts the valve opening according to the preset control algorithm and strategy, and uploads the relevant data to the cloud or local control system through the communication module for further analysis and management. The cloud control system or local control system receives the data uploaded by the IoT valve, analyzes and manages it, and optimizes the operation of the entire heating system. These data can be used to optimize the operating parameters of the heating system, predict equipment failures, etc., providing strong support for the intelligent management of the heating system.

[0059] Optionally, in one embodiment, Figure 4 As shown in FIG. 1 , the IoT valve is installed in the heating pipe for water supply and return water in the building. The corresponding operation process is as follows: when the system is started, the water supply temperature sensor (T1) and the return water temperature sensor (T2) start working to monitor the temperature of the water in the pipe in real time. For example, the temperature monitored by T1 is 55°C, and the temperature monitored by T2 is 45°C. The temperature data is sent to the microprocessor by the sensor through the internal communication protocol. The microprocessor receives the real-time temperature data of T1 and T2. The microprocessor analyzes the temperature difference (ΔT = 55°C - 45°C = 10°C) according to the preset control algorithm and strategy. Assume that the control strategy is to maintain ΔT at about 15°C, and the current ΔT is too small. The microprocessor calculates the valve opening that needs to be increased to increase the water supply flow, thereby increasing the return water temperature and reducing ΔT. The microprocessor sends a signal to the electric actuator to adjust the valve opening. After receiving the signal from the microprocessor, the electric actuator adjusts the valve opening, for example, increasing the opening from 50% to 60%.

[0060] After completing the valve adjustment, the microprocessor uploads the current temperature data, valve opening, and the adjusted results to the cloud or local control system through the communication module. For example, the uploaded data includes: T1 = 55 ° C, T2 = 45 ° C, valve opening = 60%.

[0061] After receiving these data, the cloud or local control system will conduct a comprehensive analysis to determine whether the optimal state has been achieved. If the analysis shows that the heat distribution of the entire heating system is uneven, or there is a need to adjust other valves, the system will send control signals to other IoT valves to adjust their openings based on the overall optimization strategy.

[0062] Through the above process, the self-powered IoT valve based on temperature difference power generation can dynamically and intelligently adjust the water flow and temperature in the pipeline network, realize energy-saving, efficient and stable operation of the heating system, and at the same time improve the intelligent management level of the entire system through interaction with the cloud or local control system.

[0063] Through the above embodiments, considering the impact of environmental factors such as temperature fluctuations and humidity changes on the system, the temperature difference of the environment where the valve is located (such as the temperature difference between the inside and outside of the pipeline) is used to generate electricity through thermoelectric materials to provide a stable power supply for the IoT valve. This self-powered mode reduces the dependence on external power supply, improves the reliability and stability of the system, establishes an effective monitoring and maintenance mechanism, facilitates operation and maintenance personnel to discover and solve problems in a timely manner, and improves the operational stability of the system.

[0064] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0065] In this embodiment, a control system for a self-powered IoT valve is also provided, which is used to implement the above-mentioned embodiments and preferred implementations, and will not be repeated here. As used below, the term "module" can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0066] Figure 5It is a structural block diagram of a control system of a self-powered Internet of Things valve according to an embodiment of the present application, the device includes: multiple self-powered Internet of Things valves 52 and a cloud control platform 54, wherein the cloud control platform is used to provide a control strategy for the multiple self-powered Internet of Things valves, wherein each self-powered Internet of Things valve is used to execute the acquisition of pipeline sensing parameters obtained by monitoring the heating pipeline, wherein the pipeline sensing parameters at least include the current pipeline temperature of the heating pipeline and the hot water flow in the heating pipeline; when it is determined that the current pipeline temperature is inconsistent with the heating temperature set for the heating pipeline in the preset control strategy, the regulating flow required to regulate the hot water flow is determined according to the temperature difference between the current pipeline temperature and the heating temperature; the valve opening is adjusted based on the valve opening adjustment value corresponding to the regulating flow until the current pipeline temperature reaches the heating temperature.

[0067] Through the above device, at the same time. This control system can not only realize the precise control of a single valve, but also realize the coordinated control of multiple valves through the cloud control platform, which improves the intelligence level and energy management efficiency of the entire heating system, and is suitable for heating systems of various sizes, from family homes to large commercial and industrial facilities, and can achieve efficient and intelligent temperature management.

[0068] In addition, the control system can also dynamically adjust the control strategy according to real-time weather data, changes in user demand and other factors to achieve more refined energy management. For example, when it is predicted that the weather will get colder, the valve opening is adjusted in advance to increase the hot water flow to keep the temperature of the heating pipe stable and avoid the impact of sudden temperature drops on the system; when the user is not at home or does not need heating, the cloud control platform automatically reduces the valve opening and reduces the hot water flow, thereby saving energy and reducing operating costs. This intelligent energy management method not only improves energy utilization efficiency, but also provides users with a more comfortable and convenient user experience. It is an important direction for the development of future heating systems.

[0069] In an exemplary embodiment, the self-powered Internet of Things valve is also used to: when it is determined that the current pipeline temperature is lower than the heating temperature and the temperature difference is lower than a preset difference, calculate the water supply flow required to increase the current pipeline temperature, and determine the water supply flow as the regulating flow.

[0070] In an exemplary embodiment, the self-powered IoT valve is also used to: generate a valve control signal based on the valve opening adjustment value, and control the valve opening to increase the valve opening adjustment value based on the current opening value according to the valve control signal, or control the valve opening to reduce the valve opening adjustment value based on the current opening value according to the valve control signal.

[0071] In an exemplary embodiment, the self-powered Internet of Things valve is also used to: adjust the valve opening based on the valve opening adjustment value corresponding to the regulated flow until the current pipe temperature reaches the heating temperature, and then synchronize the current pipe temperature of the heating pipe, the hot water flow in the heating pipe and the valve opening of the heating pipe to the cloud server, so that the cloud server adjusts the control strategy for other self-powered Internet of Things valves according to the current pipe temperature of the heating pipe, the hot water flow in the heating pipe and the valve opening of the heating pipe.

[0072] An embodiment of the present application further provides a computer-readable storage medium, in which a computer program is stored, wherein the computer program is configured to execute the steps of any of the above method embodiments when running.

[0073] Optionally, in this embodiment, the storage medium may be configured to store a computer program for performing the following steps:

[0074] S1, acquiring pipeline sensing parameters obtained by monitoring a heating pipeline, wherein the pipeline sensing parameters at least include a current pipeline temperature of the heating pipeline and a hot water flow rate in the heating pipeline;

[0075] S2, when it is determined that the current pipe temperature is inconsistent with the heating temperature set for the heating pipe in the preset control strategy, determining the regulating flow required to regulate the hot water flow according to the temperature difference between the current pipe temperature and the heating temperature;

[0076] S3, adjusting the valve opening based on the valve opening adjustment value corresponding to the regulated flow until the current pipeline temperature reaches the heating temperature.
