Description

Technical Field

[0001] This invention relates to the field of water supply equipment control technology, specifically to a control method and control system for secondary water supply equipment. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the demand for water supply systems is increasing day by day. The rapid development of high-rise buildings, the construction of large industrial parks, and the rise of tourist resorts have all placed higher demands on the stability, reliability, and intelligence of water supply systems. In traditional water supply systems, water pressure support is mainly provided by a single water pump or water supply facility. However, this method often shows obvious limitations when facing complex and ever-changing water use environments.

[0003] First, traditional water supply systems face certain bottlenecks in high-rise buildings. Due to the significant height differences in high-rise buildings, water pressure varies with floor level. If the water supply system cannot adjust in real time according to the water demand of different floors, it often leads to insufficient water supply for residents on higher floors, while residents on lower floors may face excessively high water pressure. This not only affects the daily water experience of residents but may also damage the water supply pipes. Traditional water supply methods typically rely on booster pump stations to solve this problem, but due to the fixed output characteristics of booster pump stations, it is difficult to achieve precise control of water supply and energy-saving optimization.

[0004] Secondly, in large industrial parks, the water demands of different factories vary greatly, and due to the frequent start-ups and shutdowns of production equipment, the water supply system needs to have strong dynamic adjustment capabilities. Traditional water supply systems, when faced with such a complex and variable water environment, often resort to oversupply to ensure that there is no water shortage during peak demand periods. However, this approach leads to significant water waste and high energy consumption, failing to meet the energy conservation and emission reduction requirements of modern industry. Furthermore, if the water supply system does not respond promptly to a sudden surge in water demand at a particular factory, it may cause serious consequences such as factory shutdowns.

[0005] Municipal water supply systems cover a wide area, serve a large population, and are affected by various factors such as weather, season, and time of day. The design and management of municipal water supply systems must comprehensively consider these complex factors. Traditional water supply systems often lack sufficient flexibility and response capabilities when dealing with sudden water demand or extreme weather events. For example, during the high temperatures of summer, residential water demand surges, and traditional water supply systems may struggle to quickly adjust the supply, leading to water shortages in some areas. Conversely, during nighttime or off-peak hours when water demand is lower, traditional systems continue to operate at high loads, resulting in significant energy waste.

[0006] The rise of smart homes has further highlighted the limitations of traditional water supply systems. As more and more families adopt smart devices for daily management, home water supply systems also need to be intelligent and automated to meet the personalized water needs of different family members at different times. Traditional home water supply systems typically cannot flexibly adjust to real-time water demand, leading to insufficient water pressure during peak hours or wasted energy during off-peak hours. Furthermore, traditional systems are inadequate in detecting and responding to sudden water supply problems (such as pipe leaks), making it difficult to react promptly through remote control and instant notifications, thus posing a threat to household water safety.

[0007] In tourist resorts, especially those located in mountainous or coastal areas, water demand fluctuates significantly due to seasonal changes in visitor numbers. Traditional water supply systems struggle to flexibly adapt to these changes, typically relying on manual adjustments or increasing equipment redundancy—inefficient and unsustainable in the long run. Furthermore, resort water systems must address unique challenges arising from their geographical location, such as unstable water pressure at high altitudes or water quality issues in coastal areas. This necessitates a higher level of intelligence and automation in water supply systems.

[0008] In recent years, with the rapid development of emerging technologies such as the Internet of Things (IoT), big data, and artificial intelligence (AI), the intelligent upgrading of water supply systems has become possible. By monitoring the operating status of the water supply system in real time through sensor networks, using big data analysis to predict water demand, and combining artificial intelligence algorithms to achieve adaptive adjustment of the system, intelligent water supply systems can significantly improve energy efficiency, reduce water waste, and provide safer and more reliable water supply services while ensuring water supply stability.

[0009] Based on this, this invention proposes a control method and control system for secondary water supply equipment, aiming to solve problems such as unstable water pressure, energy waste, and insufficient emergency response capabilities in existing water supply systems through intelligent regulation. The system can monitor water pressure, flow rate, and the operating status of water-using equipment in the supply pipeline in real time. It calculates the required water supply volume through a control algorithm and automatically adjusts the operating parameters of the water pump according to actual needs to achieve efficient, energy-saving, and stable water supply. The system also has emergency handling capabilities, reacting quickly to detected anomalies to ensure the safety and continuity of the water supply system. This innovative control method and system demonstrates broad applicability and significant technical advantages in various application scenarios, including high-rise buildings, industrial parks, municipal water supply networks, smart homes, and tourist resorts.

[0012] Step 1: Monitor the water pressure P(t), water flow rate Q(t), and operating status of water-using equipment in the water supply pipeline in real time using sensors;

[0013] Step 2: Based on the monitored data, calculate the current required water supply Q using the following control formula. desired (t), and control the start / stop and operating frequency of the water pump:

[0014] Q desired (t)=K1·Q(t)+K2·P(t)+K3·ΔQ(t)

[0015] Where K1, K2, and K3 are control coefficients, and ΔQ(t) is the instantaneous rate of change of water flow.

[0016] Step 3: When the water consumption Q(t) changes, automatically adjust the operating parameters F(t) of the water pump to ensure that the water supply Q... output (t) and water demand Q desired (t) matches;

[0017] Step 4: Set the safety thresholds for water pressure P(t) and water flow rate Q(t). If the set values ​​are exceeded, the system will issue an alarm and activate the emergency plan.

[0019] As a preferred embodiment of the present invention, the adjustment of the pump operating parameters F(t) in step 3 includes changing the pump frequency f(t) and power P. pump (t), satisfying the following condition:

[0020] Q output (t)=F(t)·Q desired (t)

[0021] Where F(t) is the adjustment coefficient of the water pump.

[0022] As a preferred technical solution of the present invention, the frequency f(t) and power P of the water pump are... pump The adjustment of (t) is based on the following formula:

[0023]

[0024] Where F(t) is the adjustment coefficient of the water pump.

[0025] As a preferred technical solution of the present invention, the frequency f(t) and power P of the water pump are... pump The adjustment of (t) is based on the following formula:

[0026]

[0027] Among them, f base P is the reference frequency of the water pump. base As the reference power, Q max This is the maximum water supply.

[0029] As a preferred technical solution of the present invention, the emergency plan includes starting a backup water pump, reducing the water supply pressure, or temporarily interrupting the water supply to some water-using equipment to ensure the overall stability of the system.

[0030] This invention also proposes a control system for a secondary water supply equipment, comprising the following modules:

[0035] As a preferred technical solution of the present invention, the sensor module includes a water pressure sensor, a water flow sensor and a temperature sensor. The temperature sensor is used to monitor the water supply temperature and adjust the operating parameters of the water pump according to the temperature change.

[0036] As a preferred technical solution of the present invention, when the emergency module detects a system fault or abnormality, it immediately starts the backup water supply system or issues a fault alarm, and the backup water supply system includes an independent water pump and control unit to ensure that basic water supply can still be maintained when the main water supply system fails.

[0037] Compared with existing technologies, the advantages of this invention are: Firstly, by monitoring the water pressure and flow rate in the water supply pipeline in real time and dynamically adjusting the operating status of the water pump using an intelligent control algorithm, the stability of the water supply system is significantly enhanced. Under different water demand scenarios, this invention can ensure constant water supply pressure, making it particularly suitable for high-rise buildings and industrial parks, avoiding the problems of insufficient or excessive water supply common in traditional systems.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1: Application of water supply system in high-rise residential buildings

[0043] In a high-rise residential building, water demand varies significantly over time. To ensure that each household receives stable water pressure and volume during both peak and off-peak periods, the system employs the following control methods:

[0044] Water supply demand calculation formula

[0045] Q desired *t(=K1·Q*t(+K2·P(t)+K3·ΔQ(t)

[0046] Among them, Q desired (t) represents the current required water supply, K1, K2, and K3 are control coefficients, and ΔQ(t) represents the instantaneous rate of change of water flow.

[0047] Water pump frequency adjustment formula

[0048]

[0049] Where f(t) is the current operating frequency of the water pump, f base Q is the reference frequency of the water pump. max This represents the system's maximum water supply.

[0050] Water pump power adjustment formula

[0051]

[0052] Among them, P pump (t) represents the current power of the water pump, P base This is the reference power.

[0053] Control Logic: In the system, sensors monitor the water pressure P(t) and water flow rate Q(t) in the water supply pipeline in real time. When an increase in water demand is detected (such as during the morning peak), the system increases the operating frequency and power of the water pumps according to a calculation formula to ensure that the water supply can meet the needs of residents. Conversely, when water demand is low at night, the system automatically reduces the frequency and power of the water pumps to achieve energy saving.

[0054] Emergency response: When the water pressure P(t) or water flow rate Q(t) exceeds the safety threshold, the system will immediately trigger the emergency plan, start the backup water pump or issue an alarm to ensure the continuity and safety of the water supply system.

[0055] Example 2: Application of Water Supply System in Industrial Park

[0056] In large industrial parks, the water demand of each factory building fluctuates significantly. To meet the water supply needs of different factory buildings, the system needs to regulate the water supply independently for each area.

[0057] Regional water supply demand calculation formula

[0058]

[0059] Among them, Q zone (t) represents the total water demand in the region, Q i (t) and P i (t) represent the water flow rate and water pressure of the i-th plant, respectively, and K... 1i and K 2i This is the control coefficient for the factory building.

[0060] Multi-regional adjustment formula

[0061]

[0062] Where F*t is the adjustment coefficient, used to control the operating parameters of the water pumps in this area.

[0063] Control logic: Sensor modules installed in each plant monitor water pressure and flow rate in real time. Based on the real-time water usage data of each plant, the system calculates the total water supply demand for the area and dynamically adjusts the operating frequency and power of the water pumps to ensure that each plant receives sufficient water and that the overall water supply system operates stably.

[0064] Emergency Response: If the water demand of a certain plant suddenly increases, or if an abnormal situation such as a pipeline leak is detected, the system will quickly adjust the water supply strategy for that area, start the backup water pump, and notify the management personnel through the communication module.

[0065] Example 3: Application in Municipal Water Supply Systems

[0066] The complexity of municipal water supply systems necessitates more precise and comprehensive control methods. These systems cover a wide area, and water demand is influenced by multiple factors, such as weather, season, and time of day.

[0067] Formula for calculating the city's water supply demand

[0068]

[0069] Among them, Q city (t) represents the total water supply demand across the entire city, Q j (t) and P j (t) represents the water flow rate and water pressure of the j-th block, K 1j and K 2j This is the control coefficient for this block.

[0070] Overall system adjustment formula

[0071]

[0074] Emergency Response: In the face of sudden surges in water demand or pipeline leaks, the system can quickly adjust its water supply strategy or activate backup pumps to ensure the normal operation of the water supply network. Through its communication module, the system can also notify municipal management departments in real time to conduct on-site handling.

[0075] Example 4: Application in Smart Home Water Supply Management

[0076] The widespread adoption of smart homes has placed new demands on the intelligent management of household water supply. Control methods for household water supply systems need to balance energy conservation and water supply stability.

[0077] Household water demand calculation formula

[0078] Q home (t)=K1·Q(t)+K2·P(t)

[0079] Among them, Q home (t) represents the current water demand of the household, and K1 and K2 are control coefficients.

[0080] Household water pump adjustment formula

[0081]

[0082] Among them, f home (t) and P home (t) represents the current frequency and power of the household water pump, respectively.

[0083] Control logic: The system monitors water pressure and flow rate in real time through sensors installed on the household water supply pipes, and automatically adjusts the operation of the water pump to ensure that the household has sufficient water during peak water usage periods (such as morning or dinner time), while reducing the operating frequency and power of the water pump during off-peak periods to achieve energy saving.

[0084] Emergency Response: When a pipe leak or water equipment malfunction is detected, the system automatically shuts off the main water supply valve and sends an alert to the user via smart home devices (such as a mobile app or smart speaker) to prevent further losses.

[0085] Example 5: Application in the water supply system of a tourist resort

[0086] The water supply needs of tourist resorts vary significantly in time and space. To address these variations, the system requires independent water supply management for different areas.

[0087] Formula for calculating water supply demand in resort areas

[0088]

[0089] Among them, Q resort (t) represents the total water demand of the resort area, Q k (t) and P k (t) represents the water flow rate and water pressure in the k-th region, K 1k and K 2k This is the control coefficient for this region.

[0090] Water supply system regulation formula

[0091]

[0092] The system uses this adjustment coefficient F resort (t) Dynamically adjust the pump parameters in each area to ensure reasonable water supply distribution and energy conservation.

[0093] Control Logic: Sensor modules are installed at each major water supply node within the resort to monitor the water supply situation in real time. Based on the monitored data, the system automatically calculates the water demand for each area and adjusts the frequency and power of the water pumps to adapt to the water demand of different areas and time periods. For example, the system increases the water supply in the pool area where tourists congregate during the day, and reduces the water supply at night or in areas with fewer tourists.

[0094] Emergency Response: When an abnormal water pressure or flow rate is detected in a certain area, the system will immediately adjust the water supply strategy for that area and notify the resort management personnel to handle the situation on-site to ensure the continuity of the water supply system.
