Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring and regulation of heating systems, and in particular to a heating pipeline flow intelligent regulation system and method. Background Art

[0002] With the development of social economy and the improvement of residents' living standards, people's requirements for indoor comfort are getting higher and higher, especially during winter heating. Traditional heating systems often have the following problems:

[0003] Limited regulation accuracy: The regulation of some systems is not precise enough, making it difficult to achieve subtle and accurate control of the flow rate, resulting in the heating effect not being able to fully meet the user's personalized needs, and there being large fluctuations in indoor temperature or uneven temperatures in different areas.

[0004] Slow response speed: When indoor and outdoor environmental conditions (such as outdoor temperature, user demand, etc.) change, the system's response to flow regulation may be slow, and it may not be able to make corresponding adjustments in time according to the changes, so that the indoor temperature cannot quickly reach a comfortable state within a period of time.

[0005] Energy waste: Some flow regulation systems cannot dynamically and intelligently adjust the flow according to actual needs. They may maintain a high flow when a large amount of heating is not needed, or fail to increase the flow in time when it is needed, resulting in energy waste and increased heating costs.

[0006] Lack of intelligent prediction and optimization functions: It is impossible to intelligently predict and optimize future heating demand and flow based on historical data, weather forecasts and other information, and it is impossible to formulate reasonable flow regulation strategies in advance, resulting in difficulty in further improving the efficiency of system operation and energy-saving effects. Summary of the invention

[0007] In view of the above existing problems, the present invention aims to achieve accurate control and optimal regulation of the flow rate of the heating pipeline to improve heating efficiency, save energy, and meet the personalized heating needs of different users. By adopting advanced sensor technology, automatic control technology and intelligent algorithms, the system can monitor the operating parameters of the heating pipeline in real time and automatically adjust the flow rate according to the preset strategy to ensure the stable operation and high efficiency and energy saving of the heating system.

[0008] In order to solve the above technical problems, a heating pipeline flow intelligent regulation system is proposed, which includes a sensor module, a control module, a communication module, a human-computer interaction interface and a power module;

[0009] The sensor module includes a temperature sensor, a pressure sensor, and a flow sensor;

[0010] The control module includes a central controller and an electronically controlled valve;

[0011] The communication module establishes a wired or wireless communication network, performs stable data transmission between the sensor module and the control module, supports communication with a remote monitoring center or a user terminal, and has remote monitoring and management functions. The user can view the heating status and set the target temperature in real time through the terminal device;

[0012] The human-computer interaction interface provides an intuitive and easy-to-use operation interface, which is convenient for users to set parameters and select modes, and displays the system's operating status, temperature, pressure, and flow rate in real time, as well as historical data query and report generation functions;

[0013] The power module has a backup power supply or power protection function to cope with sudden power outages, provide a stable power supply for each component of the system, and ensure the normal operation of the system.

[0014] As a preferred solution of the heating pipeline flow intelligent regulation system of the present invention, wherein: the sensor module includes: the temperature sensor is installed at the entrance and exit areas of the household heating pipeline and the user's room to monitor the temperature changes at different locations in real time to provide a basis for flow regulation;

[0015] The pressure sensor is arranged at a key position of the heating pipeline to detect the pressure change in the pipeline and determine whether there is leakage or blockage in the pipeline;

[0016] The flow sensor is installed on the inlet pipe and the outlet pipe to measure the flow of the fluid, calculate the user's heat usage, and adjust the flow.

[0017] As a preferred solution of the heating pipeline flow intelligent regulation system described in the present invention, wherein: the control module includes, the central controller as the core of the system, receives the data collected by the sensor, performs data analysis and processing, and issues control instructions according to the preset algorithm and strategy to control the opening of the flow regulating valve;

[0018] The electric control valve is installed between the inlet and outlet of the household heating pipe, and controls the flow rate of the fluid in the pipe and adjusts the flow rate according to the instructions of the central controller.

[0019] Another intelligent method for regulating the flow of a heating pipe of the present invention aims to automatically regulate the flow of hot water in the heating pipe according to factors such as indoor and outdoor temperature and user demand, thereby achieving energy-saving operation of the heating system and ensuring the heating quality of users.

[0020] As a preferred solution of the method for intelligently regulating the flow rate of a heating pipeline according to the present invention, it is characterized by comprising:

[0021] The user logs into the system through the human-computer interaction interface, enters the basic information of the user's first-time use, such as the set location, room specifications, and initial temperature, and sets the target temperature and personalized time period. The system automatically connects all sensors and control modules.

[0022] The system monitors indoor temperature, pressure and flow data in real time, calculates the required flow regulation and adjusts the opening of the electronically controlled valve according to the deviation between the set target temperature and the actual temperature;

[0023] The user checks the flow and pressure of each branch, and the system analyzes whether there is hydraulic imbalance. When the system detects that the flow of any branch is insufficient or excessive, it adjusts the branch flow;

[0024] When the system detects abnormal conditions, including excessive temperature and abnormal pressure, a warning prompt will pop up, and the user can access the alarm information to view the fault type, affected area and recommended treatment measures.

[0025] As a preferred solution of the intelligent regulation system for the flow of heating pipelines described in the present invention, wherein: the adjustment of the opening of the electronically controlled valve includes: the user selects the room or area to be regulated in the interface, selects the personalized setting, sets the target temperature for different time periods according to the user's weekly living habits, and after confirming the target temperature, clicks the save button, and the system records the current setting;

[0026] The system monitors indoor temperature, pressure and flow data in real time, calculates the difference between the target temperature set by the user and the actual indoor temperature, and defines a dynamic adjustment factor based on the difference and combines it with the proportional coefficient determined by historical data to convert the temperature difference into the required flow change. When the difference is greater than 5°C, the dynamic adjustment factor is set to 1.5; when the difference is greater than 3°C but not more than 5°C, the dynamic adjustment factor is set to 1.2; when the difference is greater than 1°C but not more than 3°C, the dynamic adjustment factor is set to 1; when the difference is less than 1°C, the dynamic adjustment factor is set to 0.8;

[0027] When the difference is greater than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 90% to increase the heating flow;

[0028] When the difference is greater than 0°C and less than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 50% to increase the heating flow;

[0029] When the difference is less than 0°C, the opening of the electronically controlled valve is adjusted based on the calculated flow change and valve flow coefficient, and the valve opening is reduced to 30% to reduce the heating flow.

[0030] As a preferred solution of the method for intelligently regulating the flow of a heating pipeline described in the present invention, the hydraulic imbalance phenomenon includes: by monitoring and analyzing the flow and pressure data of each branch of the heating pipeline, the flow and pressure data of all heating branches are collected in real time every 5 minutes. When the flow deviation of any branch exceeds ±10% of the normal flow, the system will identify the existence of hydraulic imbalance and adjust the flow distribution of each branch. When the flow of the branch with hydraulic imbalance exceeds 1.5m 3 / h, the opening of the electric control valve of the current branch is automatically reduced by 10% to reduce the flow rate;

[0031] When there is hydraulic imbalance, the branch flow is less than 1.0m 3 / h, the electric control valve opening of the current branch will be automatically increased by 10% to increase the flow rate;

[0032] If any branch is in an unbalanced state during three consecutive monitoring cycles, the system will trigger an alarm and notify the user through the communication module for maintenance. After the alarm, the flow adjustment frequency will be increased to once every 1 minute, and the overall energy efficiency of the heating system will be evaluated every month. When the flow and pressure of any branch continue to be lower than the set overall energy efficiency target, optimization suggestions will be provided to the user whether it is necessary to adjust the pipeline layout or add auxiliary equipment.

[0033] As a preferred solution of the intelligent regulation system for heating pipeline flow of the present invention, the branch flow adjustment includes evaluating and optimizing the operation status of the heating system based on real-time temperature, pressure and flow data in combination with intelligent algorithms, obtaining the energy required to change the temperature by multiplying the mass flow rate of the fluid by the specific heat capacity, and obtaining the comprehensive performance of the heating system by multiplying the temperature difference between the fluid entering and leaving the room to determine the optimal flow regulation strategy:

[0034] The first stage is used to determine the direction of increasing or decreasing the flow rate. When the evaluation result is less than the minimum heat demand threshold, it means that the current heat supply does not meet the demand and the flow rate needs to be increased to meet the demand. When the evaluation result exceeds the minimum heat demand threshold, the heating demand is met and the second stage is entered to further optimize the flow rate.

[0035] The second stage of judgment is carried out to ensure that the pressure situation under the direction of the first stage judgment meets the safety standards. When the real-time measured pressure of the heating pipe is less than the minimum value of the specified safety standard range, it indicates that the pressure is too low and the system is unstable. When the real-time measured pressure of the heating pipe is greater than the maximum value of the specified safety standard range, it indicates that the pressure is too high and the system is at risk of overpressure. When the real-time measured pressure of the heating pipe is within the specified safety standard range, the flow rate continues to be adjusted according to the first stage judgment result.

[0036] The third stage is to determine whether the flow rate adjusted according to the current flow rate regulation strategy is within a reasonable range to achieve the best heating effect and energy consumption control;

[0037] If the flow rate is lower than the minimum threshold, it is necessary to further increase the flow rate based on the direction determined in the first stage; if the flow rate is higher than the maximum threshold, it is necessary to further reduce the flow rate based on the direction determined in the first stage to reduce energy consumption; if the flow rate is within the normal range, the current flow rate setting is maintained and enters the stable stage. The user's comfortable temperature has been achieved, and the system maintains the current flow rate setting as the optimal flow regulation strategy.

[0038] As a preferred solution of the intelligent regulation system of the heating pipeline flow described in the present invention, the pop-up warning prompt includes real-time monitoring of the operating parameters of the system, and when abnormal conditions such as abnormal temperature, abnormal pressure, abnormal flow or equipment failure occur, an alarm signal is issued, and the fault information is sent to the remote monitoring center and the user terminal, and a preliminary analysis and judgment of the fault is performed to provide a reference for maintenance personnel, shorten the troubleshooting time, and store the temperature, pressure, and flow data during the system operation in real time, establish a historical database, and through the analysis of historical data, understand the user's heating habits and the operating laws of the heating system, and formulate energy-saving measures.

[0039] A computer device includes a memory and a processor, wherein the memory stores a computer program, and is characterized in that the processor implements the steps of the intelligent regulation system for the flow of a heating pipeline when executing the computer program.

[0040] A computer-readable storage medium having a computer program stored thereon, characterized in that when the computer program is executed by a processor, the steps of the intelligent regulation system for the flow of a heating pipeline are implemented.

[0041] Beneficial effects of the present invention: The present invention can monitor pipeline flow in real time, and accurately adjust the opening of the flow control valve according to preset strategies (such as indoor temperature requirements, heating requirements at different time periods, etc.), to ensure that the actual flow matches the required flow, and effectively avoid the problem of insufficient heating or energy waste caused by excessive or insufficient flow. For example, when the indoor temperature is lower than the set temperature, the system will automatically increase the flow to improve the heating effect; conversely, when the indoor temperature reaches or exceeds the set temperature, the system will reduce the flow to achieve on-demand heating.

[0042] Through precise flow regulation, the indoor temperature can be kept relatively stable within a comfortable range, reducing temperature fluctuations and improving the user's comfort experience. Even when the outdoor temperature changes or the user's heating demand changes, the flow rate can be quickly responded and adjusted to maintain a stable indoor temperature.

[0043] Flow regulation based on actual demand avoids unnecessary energy consumption, improves energy efficiency, and helps achieve the goal of energy conservation and emission reduction. While meeting the heating needs of users, it also reduces the energy costs of heating companies.

[0044] The system can monitor flow, pressure, temperature and other parameters in real time. When abnormal situations occur (such as abnormal flow changes, too high or too low pressure, temperature sensor failure, etc.), it can promptly diagnose and issue early warning signals to remind relevant personnel to carry out maintenance and processing, avoid the expansion of faults, and ensure the safe and stable operation of the heating system. For example, when a pipeline leaks and causes abnormal flow, the system can quickly detect and notify maintenance personnel.

[0045] Stable heating temperature and precise flow control greatly improve the heating quality, allowing users to enjoy a more comfortable indoor environment and reducing user complaints and disputes caused by uneven heating. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Embodiment 3 is the third embodiment of the present invention, which provides a method for intelligently regulating the flow of a heating pipeline, comprising:

[0069] S1. The user logs in to the system through the human-computer interaction interface, enters the basic information of the user's setting location, room specifications, initial temperature when using for the first time, and sets the target temperature and personalized setting time period. The system automatically connects all sensors and control modules;

[0070] S2. The system monitors the indoor temperature, pressure and flow data in real time, calculates the required flow regulation and adjusts the opening of the electronically controlled valve according to the deviation between the set target temperature and the actual temperature;

[0071] It should be noted that the user selects the room or area to be adjusted in the interface, selects personalized settings, sets the target temperature for different time periods according to the user's weekly living habits, confirms the target temperature, and clicks the Save button, and the system records the current setting;

[0072] The system monitors indoor temperature, pressure and flow data in real time, calculates the difference between the target temperature set by the user and the actual indoor temperature, and defines a dynamic adjustment factor based on the difference and combines it with the proportional coefficient determined by historical data to convert the temperature difference into the required flow change. When the difference is greater than 5°C, the dynamic adjustment factor is set to 1.5; when the difference is greater than 3°C but not more than 5°C, the dynamic adjustment factor is set to 1.2; when the difference is greater than 1°C but not more than 3°C, the dynamic adjustment factor is set to 1; when the difference is less than 1°C, the dynamic adjustment factor is set to 0.8;

[0073] When the difference is greater than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 90% to increase the heating flow;

[0074] When the difference is greater than 0°C and less than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 50% to increase the heating flow;

[0075] When the difference is less than 0°C, the opening of the electronically controlled valve is adjusted based on the calculated flow change and valve flow coefficient, and the valve opening is reduced to 30% to reduce the heating flow.

[0076] S3. The user checks the flow and pressure of each branch, and the system analyzes whether there is hydraulic imbalance. When the system detects that the flow of any branch is insufficient or excessive, it adjusts the branch flow;

[0077] Furthermore, by monitoring and analyzing the flow and pressure data of each branch of the heating pipeline, the flow and pressure data of all heating branches are collected in real time every 5 minutes. When the flow deviation of any branch exceeds ±10% of the normal flow, the system will identify it as a hydraulic imbalance and adjust the flow distribution of each branch. When the flow of the branch with hydraulic imbalance exceeds 1.5m 3 / h, the opening of the electric control valve of the current branch is automatically reduced by 10% to reduce the flow rate;

[0078] When there is hydraulic imbalance, the branch flow is less than 1.0m 3 / h, the electric control valve opening of the current branch will be automatically increased by 10% to increase the flow rate;

[0079] If any branch is in an unbalanced state during three consecutive monitoring cycles, the system will trigger an alarm and notify the user through the communication module for maintenance. After the alarm, the flow adjustment frequency will be increased to once every 1 minute, and the overall energy efficiency of the heating system will be evaluated every month. When the flow and pressure of any branch continue to be lower than the set overall energy efficiency target, optimization suggestions will be provided to the user whether it is necessary to adjust the pipeline layout or add auxiliary equipment.

[0080] It should be noted that based on real-time temperature, pressure and flow data, combined with intelligent algorithms, the operating status of the heating system is evaluated and optimized. The energy required to change the temperature is obtained by multiplying the mass flow rate of the fluid by the specific heat capacity. By multiplying the temperature difference between the fluid entering and leaving the room, the comprehensive performance of the heating system is evaluated and the optimal flow regulation strategy is determined:

[0081] The first stage is used to determine the direction of increasing or decreasing the flow rate. When the evaluation result is less than the minimum heat demand threshold, it means that the current heat supply does not meet the demand and the flow rate needs to be increased to meet the demand. When the evaluation result exceeds the minimum heat demand threshold, the heating demand is met and the second stage is entered to further optimize the flow rate.

[0082] The second stage of judgment is carried out to ensure that the pressure situation under the direction of the first stage judgment meets the safety standards. When the real-time measured pressure of the heating pipe is less than the minimum value of the specified safety standard range, it indicates that the pressure is too low and the system is unstable. When the real-time measured pressure of the heating pipe is greater than the maximum value of the specified safety standard range, it indicates that the pressure is too high and the system is at risk of overpressure. When the real-time measured pressure of the heating pipe is within the specified safety standard range, the flow rate continues to be adjusted according to the first stage judgment result.

[0083] The third stage is to determine whether the flow rate adjusted according to the current flow rate regulation strategy is within a reasonable range to achieve the best heating effect and energy consumption control;

[0084] If the flow rate is lower than the minimum threshold, it is necessary to further increase the flow rate based on the direction determined in the first stage; if the flow rate is higher than the maximum threshold, it is necessary to further reduce the flow rate based on the direction determined in the first stage to reduce energy consumption; if the flow rate is within the normal range, the current flow rate setting is maintained and enters the stable stage. The user's comfortable temperature has been achieved, and the system maintains the current flow rate setting as the optimal flow regulation strategy.

[0085] S4. When the system detects abnormal conditions including excessive temperature and abnormal pressure, a warning prompt will pop up and the user can access the alarm information to view the fault type, affected area and recommended treatment measures.

[0086] Specifically, the system's operating parameters are monitored in real time. When abnormal temperature, pressure, flow or equipment failure occurs, an alarm signal is issued, and the fault information is sent to the remote monitoring center and user terminal. The fault is initially analyzed and judged to provide reference for maintenance personnel, shortening the troubleshooting time. The temperature, pressure and flow data during the system operation are stored in real time, and a historical database is established. Through the analysis of historical data, the user's heating habits and the operating rules of the heating system are understood, and energy-saving measures are formulated.

[0087] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.

The method for intelligently regulating the flow rate of a heating pipeline according to claim 4, characterized in that: The adjustment of the opening of the electronically controlled valve includes the user selecting the room or area to be adjusted in the interface, selecting personalized settings, setting target temperatures for different time periods according to the user's weekly living habits, and after confirming the target temperature, clicking the Save button, and the system records the current setting; The system monitors indoor temperature, pressure and flow data in real time, calculates the difference between the target temperature set by the user and the actual indoor temperature, and defines a dynamic adjustment factor based on the difference and combines it with the proportional coefficient determined by historical data to convert the temperature difference into the required flow change. When the difference is greater than 5°C, the dynamic adjustment factor is set to 1.5; when the difference is greater than 3°C but not more than 5°C, the dynamic adjustment factor is set to 1.2; when the difference is greater than 1°C but not more than 3°C, the dynamic adjustment factor is set to 1; when the difference is less than 1°C, the dynamic adjustment factor is set to 0.8; When the difference is greater than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 90% to increase the heating flow; When the difference is greater than 0°C and less than 2°C, based on the calculated flow change and valve flow coefficient, the opening of the electronically controlled valve is adjusted to increase the valve opening to 50% to increase the heating flow; When the difference is less than 0°C, the opening of the electronically controlled valve is adjusted based on the calculated flow change and valve flow coefficient, and the valve opening is reduced to 30% to reduce the heating flow.

6. The method for intelligently regulating the flow rate of a heating pipeline according to claim 5, characterized in that: The hydraulic imbalance phenomenon includes: by monitoring and analyzing the flow and pressure data of each branch of the heating pipeline, the flow and pressure data of all heating branches are collected in real time every 5 minutes. When the flow deviation of any branch exceeds ±10% of the normal flow, the system will identify the existence of hydraulic imbalance and adjust the flow distribution of each branch. When the flow of the branch with hydraulic imbalance exceeds 1.5m 3 / h, the electric control valve opening of the current branch is automatically reduced by 10% to reduce the flow rate; When there is hydraulic imbalance, the branch flow is less than 1.0m 3 / h, the electric control valve opening of the current branch will be automatically increased by 10% to increase the flow rate; If any branch is in an unbalanced state during three consecutive monitoring cycles, the system will trigger an alarm and notify the user through the communication module for maintenance. After the alarm, the flow adjustment frequency will be increased to once every 1 minute, and the overall energy efficiency of the heating system will be evaluated every month. When the flow and pressure of any branch continue to be lower than the set overall energy efficiency target, optimization suggestions will be provided to the user whether it is necessary to adjust the pipeline layout or add auxiliary equipment.

7. The method for intelligently regulating the flow rate of a heating pipeline according to claim 6, characterized in that: The branch flow adjustment includes evaluating and optimizing the operation status of the heating system based on real-time temperature, pressure and flow data in combination with intelligent algorithms, obtaining the energy required to change the temperature by multiplying the mass flow rate of the fluid by the specific heat capacity, and obtaining the comprehensive performance of the heating system by multiplying the temperature difference between the fluid entering and leaving the room to determine the best flow adjustment strategy: The first stage is used to determine the direction of increasing or decreasing the flow rate. When the evaluation result is less than the minimum heat demand threshold, it means that the current heat supply does not meet the demand and the flow rate needs to be increased to meet the demand. When the evaluation result exceeds the minimum heat demand threshold, the heating demand is met and the second stage is entered to further optimize the flow rate. The second stage of judgment is carried out to ensure that the pressure situation under the direction of the first stage judgment meets the safety standards. When the real-time measured pressure of the heating pipe is less than the minimum value of the specified safety standard range, it indicates that the pressure is too low and the system is unstable. When the real-time measured pressure of the heating pipe is greater than the maximum value of the specified safety standard range, it indicates that the pressure is too high and the system is at risk of overpressure. When the real-time measured pressure of the heating pipe is within the specified safety standard range, the flow rate continues to be adjusted according to the first stage judgment result. The third stage is to determine whether the flow rate adjusted according to the current flow rate regulation strategy is within a reasonable range to achieve the best heating effect and energy consumption control; If the flow rate is lower than the minimum threshold, it is necessary to further increase the flow rate based on the direction determined in the first stage; if the flow rate is higher than the maximum threshold, it is necessary to further reduce the flow rate based on the direction determined in the first stage to reduce energy consumption; if the flow rate is within the normal range, the current flow rate setting is maintained and enters the stable stage. The user's comfortable temperature has been achieved, and the system maintains the current flow rate setting as the optimal flow regulation strategy.
