Description

Technical Field

[0001] This invention relates to the field of water pump control technology, specifically to an intelligent automatic detection and control system for water pumps adapted to construction site scenarios. It is applicable to the intelligent monitoring and control of equipment such as foundation pit drainage pumps, water supply pumps, and sewage discharge pumps in various construction sites, and is especially suitable for the operation and management of water pumps in unattended scenarios. Background Technology

[0002] In daily operations at construction sites, water pumps, as core auxiliary equipment, are widely used in several critical scenarios such as foundation pit drainage, construction site water supply, and construction wastewater discharge. Due to the complex construction environment, dispersed work areas, and long work cycles, water pumps often need to operate continuously for extended periods. Moreover, most work scenarios are limited by space and manpower, making it impossible to have dedicated personnel on-site for monitoring. This results in various abnormal operating conditions during water pump operation not being detected and handled in a timely manner, leading to equipment failure and affecting construction progress.

[0003] Currently, the most prominent problems in the operation of construction site water pumps are three abnormal operating conditions: dry pumping, debris jamming, and idling. All three conditions can directly lead to pump motor burnout, causing economic losses and severely impacting construction continuity. Dry pumping is often caused by a drop in water level in the construction site's water storage structure or blockage of the inlet by silt and debris. In this situation, the pump has no water source to draw, and the motor operates under no-load or light-load conditions. The internal mechanical seals and bearings rapidly generate high temperatures due to dry friction, leading to seal burnout, pump body overheating, and ultimately motor burnout. Idling is often caused by air leaks in the pump's inlet and outlet pipes or valves not being properly opened. Without media delivery, the motor's operating current is significantly lower, and prolonged idling can easily cause motor overheating and seal damage. Debris jamming occurs when debris from construction site sewage or silt enters the pump body, jamming the impeller or shaft, causing a sudden increase in motor load and abnormally high current. If not stopped in time, this can not only burn out the motor and damage the pump body but also potentially lead to electrical safety accidents.

[0004] Existing technologies for pump protection primarily rely on single overload or temperature protection measures, failing to comprehensively cover various abnormal operating conditions such as dry pumping, obstruction by debris, and idling. Furthermore, they lack automated control and remote monitoring capabilities, making it difficult to respond promptly to abnormal conditions in unattended scenarios and fundamentally prevent pump burn-out. While some existing intelligent pump control systems possess basic monitoring functions, they suffer from poor adaptability, failing to adapt to the harsh environments of construction sites characterized by humidity, dust, and unstable wireless signals. They also exhibit low detection accuracy, slow response speed, and inefficient fault handling, failing to meet the actual operational needs of construction site pumps. Moreover, existing systems often lack robust emergency power supply mechanisms and fault self-diagnosis functions. In the event of sudden power outages or equipment module failures at the construction site, problems such as loss of abnormal information and escalation of faults can easily occur, further impacting equipment maintenance efficiency.

[0005] Therefore, developing an intelligent control system that can adapt to unattended construction site scenarios, comprehensively and accurately detect abnormal operating conditions such as pump dry running, debris jamming, and idling, and achieve automatic shutdown protection, remote monitoring, and efficient fault handling, as well as having complete emergency support and fault self-diagnosis functions, has become the key to solving the above-mentioned technical pain points and ensuring the continuity of construction on the site. Summary of the Invention

[0006] The purpose of this invention The purpose of this invention is to overcome the shortcomings of existing technologies in construction site water pumps, such as the inability to detect and handle abnormal operating conditions like dry running, obstruction by debris, and idling in unattended scenarios, which can easily lead to motor burnout, equipment damage, and construction interruption. This invention provides an intelligent automatic detection and control system for construction site water pumps, enabling intelligent monitoring of the entire pump operation process, automatic anomaly identification, emergency shutdown protection, and remote monitoring. It eliminates the need for on-site human supervision, effectively avoiding the risk of pump burnout and ensuring stable and continuous operation of the construction site water pumps. Furthermore, by improving functions such as emergency power supply, fault self-diagnosis, and data statistical analysis, the system's reliability, practicality, and operational efficiency are further enhanced, making it suitable for the complex and harsh operating environment of construction sites. Technical solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent automatic detection and control system for construction site water pumps includes a detection module, a control module, an execution module, a communication module, and a terminal monitoring platform; The detection module is electrically connected to the control module and is used to collect various parameters and operating data during the operation of the water pump in real time, and transmit the collected raw data to the control module for processing in real time. The control module is electrically connected to the execution module and the communication module respectively. It is used to receive the raw data transmitted by the detection module, filter, calibrate and perform logical analysis on the data, and determine whether the water pump is in any one or more abnormal operating conditions such as dry pumping, debris jamming, or idling. If it is determined to be an abnormal operating condition, it immediately generates a shutdown control signal and sends it to the execution module. At the same time, it generates abnormal information containing the abnormal type and occurrence time and sends it to the communication module. The execution module is connected in series with the power supply circuit of the water pump. It is used to receive the shutdown control signal sent by the control module, quickly cut off the power supply of the water pump to realize shutdown protection, and can also receive the restart signal or the main / standby pump switching signal sent by the control module to complete the water pump restart operation or the switching action between the standby pump and the main pump. The communication module establishes a two-way communication connection with the terminal monitoring platform, which is used to push abnormal information and real-time operating status data of the water pump sent by the control module to the terminal monitoring platform, and at the same time receive manual control instructions issued by the terminal monitoring platform and transmit them to the control module for execution. The terminal monitoring platform is used to receive and visualize the water pump operating status data and abnormal information for staff to view and operate, and can send control commands such as restart, shutdown, and main / standby pump switching to the control module.

[0008] Furthermore, the detection module consists of an anti-clogging level sensor, a high-precision current sensor, a waterproof vibration sensor, a temperature sensor, and a flow sensor. These sensors work together to achieve comprehensive monitoring of the water pump's operating conditions, as detailed below: The anti-clogging level sensor is installed inside the water storage structure corresponding to the water pump inlet, preferably 10-15cm above the bottom of the water storage structure, to ensure accurate acquisition of real-time water level data at the inlet, providing core data support for judging dry pumping conditions. The sensor adopts a probe structure, and the probe surface is coated with a polytetrafluoroethylene anti-debris coating with a thickness of 0.1-0.2mm, which can effectively prevent mud, sand and debris in the construction site sewage from adhering and clogging the probe, ensuring the accuracy of water level detection. The detection accuracy can reach ±0.1cm, and the response time is ≤0.5 seconds.

[0009] The high-precision current sensor is connected in series in the power circuit of the water pump motor and uses a through-hole installation method, which eliminates the need to disconnect the power circuit, making installation convenient. It can accurately collect current data during motor operation with an accuracy of ±1%. Combined with a preset current threshold range, it can make a preliminary judgment on two abnormal operating conditions: idling and obstruction. In the idling condition, the water pump is not delivering media, the motor load is greatly reduced, and the operating current will be significantly lower than the normal operating current threshold. In the obstruction condition, the impeller or shaft is stuck by debris, the motor load increases sharply, and the operating current will be significantly higher than the normal operating current threshold. By observing the abnormal changes in current data, these two abnormal operating conditions can be quickly identified, providing a basis for subsequent accurate judgment.

[0010] The waterproof vibration sensor is fixedly installed on the surface of the water pump body using a magnetic fixing method, which facilitates installation and disassembly. It can collect vibration frequency and amplitude data during water pump operation, with a vibration frequency detection range of 10-1000Hz and an amplitude detection range of 0.01-10mm. Combined with a preset vibration threshold, it helps to determine the condition of debris jamming. The sensor adopts a fully sealed structure with an IP67 waterproof rating, which can adapt to the harsh environment of humid and dusty construction sites, extending the service life of the sensor and ensuring the stability of vibration data acquisition. When debris is jammed inside the water pump, the impeller rotation is obstructed, which will cause the pump body vibration frequency and amplitude to increase significantly, exceeding the preset vibration threshold. Combined with abnormal changes in current data, it can further improve the accuracy of judging the condition of debris jamming and avoid misjudgment caused by relying on a single data point.

[0011] The temperature sensors are installed on the pump motor housing and key parts of the pump body (such as the pump shaft connection) using a patch mounting method, which ensures a tight fit with the equipment surface. This allows for accurate real-time temperature data collection of the motor and pump body, with a temperature detection range of -20℃ to 150℃ and a detection accuracy of ±0.5℃. This prevents equipment burnout due to overheating caused by abnormal operating conditions. When the motor or pump body temperature exceeds the preset temperature protection threshold, the control module will immediately trigger a shutdown protection mechanism, regardless of whether other abnormal operating conditions exist. This prevents overheating from causing motor insulation failure and pump body damage, further enhancing the safety of equipment operation.

[0012] The flow sensor is installed on the water pump outlet pipeline, using a flange connection to accommodate pipelines of different diameters (50-200mm). It is used to collect real-time flow data from the outlet, with a flow detection range of 0.1-10 m³ / h and a detection accuracy of ±2%. In conjunction with liquid level and current data, it improves the accuracy of determining dry pumping and idling conditions. The sensor is made of corrosion-resistant stainless steel, which can withstand the erosion of acidic, alkaline, and silt media in construction site wastewater, preventing sensor damage and ensuring the accuracy of flow data acquisition. During dry pumping and idling conditions, the water pump has no effective water output, and the flow data will be significantly lower than the normal operating flow threshold. This data is cross-validated with liquid level and current data to reduce false detections and missed detections, ensuring that abnormal conditions are detected promptly.

[0013] Furthermore, the control module includes a main control microcontroller, a data processing unit, and a logic judgment unit. The main control microcontroller adopts the STM32F103 series microcontroller, which has fast processing speed and low power consumption, and can adapt to the complex power supply environment of the construction site, as detailed below: The data processing unit receives liquid level, current, vibration, temperature, and flow data transmitted by the detection module, and performs filtering, noise reduction, and error calibration on the data. The filtering process uses a Kalman filter algorithm, which can effectively eliminate signal deviations caused by electromagnetic interference and dust interference in the complex environment of the construction site. The error calibration uses a linear calibration algorithm to ensure the accuracy and reliability of the data, providing accurate data support for subsequent working condition judgment. The data processing unit also has a data caching function, which can cache the operating data of the most recent hour to avoid data loss due to communication interruption.

[0014] The logic judgment unit has preset thresholds for dry pumping, idling, debris jamming, and temperature protection. These thresholds can be flexibly adjusted according to the pump model, rated parameters, and actual construction conditions to adapt to different usage scenarios. The logic judgment unit compares and analyzes the processed accurate data with the preset thresholds to determine whether the pump is operating normally. The specific judgment logic is as follows: 1. Dry pumping condition: Liquid level data < dry pumping judgment threshold, and flow rate data < preset flow rate threshold; 2. Idle condition: Current data < idle judgment threshold, flow data < preset flow threshold, and vibration data within normal range; 3. Debris jamming condition: Vibration data > debris jamming judgment threshold, and current data > normal operating current range; 4. Overheating condition: Temperature data > temperature protection threshold.

[0015] When any one or more of the above abnormal operating conditions occur, the logic judgment unit immediately generates a shutdown control signal, and simultaneously records the abnormal data and the time of occurrence, generating complete abnormal information to provide a basis for subsequent fault tracing. The control module also integrates parameter self-learning and fault self-diagnosis functions. The parameter self-learning function can automatically iteratively adjust preset thresholds based on the water pump operation data under different construction stages and operating conditions at the construction site, optimizing the judgment accuracy of abnormal operating conditions without the need for frequent manual parameter adjustments, and can adapt to different models and different usage scenarios of construction site water pumps. The fault self-diagnosis function can monitor the operating status of the detection module, execution module, and communication module in real time. When a fault is detected in a certain module, the module fault information is immediately generated, pushed to the terminal monitoring platform, and the power supply of the corresponding associated equipment is cut off to prevent the fault from escalating.

[0016] Furthermore, the execution module includes an intermediate relay, an AC contactor, and an intelligent standby pump switching device. These components work together to achieve precise control of the water pump power supply and flexible switching between the main and standby pumps, as detailed below: The intermediate relay is connected in series with the water pump motor power supply circuit, uses DC24V power supply, and has a response time of ≤10ms. After receiving the shutdown control signal from the control module, it quickly cuts off the motor power supply to achieve emergency shutdown protection and prevent equipment damage caused by continuous abnormal operating conditions. After receiving the restart signal, it turns on the motor power supply to complete the water pump restart. After restarting, it continues to cooperate with the detection module and control module to complete the operating condition monitoring to ensure that the water pump operates normally after restarting. The intermediate relay has a status feedback function, which can feed back its own on / off status to the control module, so that the control module can determine whether the execution module is working properly.

[0017] The AC contactor works in conjunction with the intermediate relay, using AC380V power supply, and is compatible with the three-phase power supply commonly used on construction sites. It is used to control the smooth start and stop of the water pump motor, optimize the stability and reliability of power supply on / off control, prevent contact damage caused by current fluctuations, extend equipment service life, and reduce operation and maintenance costs. The AC contactor has an overload protection function, which can automatically cut off the power supply when the motor current is abnormally high, forming a double protection.

[0018] The intelligent standby pump switching device is connected to both the main pump and the standby pump. It is controlled by an intelligent control chip, with a switching time of ≤1 second. When the control module determines that the main pump is malfunctioning and cannot be quickly resolved remotely, it sends a switching signal to the standby pump switching device to cut off the power to the main pump and connect the power to the standby pump, thereby enabling the standby pump to automatically start operation. This ensures the continuity of drainage and water supply operations at the construction site and avoids construction interruptions due to main pump failure. The device also has a manual switching function, allowing staff to manually switch between the main and standby pumps on-site when the system malfunctions, further improving the system's reliability.

[0019] Furthermore, the communication module adopts a dual-mode wireless communication method, including a 4G / 5G module and a WiFi module. It can automatically switch communication modes according to the wireless signal environment of the construction site, realizing bidirectional high-speed data transmission between the control module and the terminal monitoring platform, with a data transmission rate of ≥1Mbps. Considering the problem of unstable wireless signals at construction sites, the communication module integrates a signal enhancement module, which can adapt to the complex wireless signal environment of the construction site, effectively avoid signal interruption problems, and ensure that abnormal information can be pushed in a timely manner and control commands can be transmitted accurately. The communication module is also equipped with a signal detection unit, which can monitor the communication signal strength in real time. When the signal strength is lower than a preset threshold (-80dBm), it automatically switches to the backup communication mode and pushes a communication abnormality reminder to the terminal monitoring platform, which facilitates staff to troubleshoot communication problems in a timely manner. The communication module adopts an IP65 waterproof rating, which can adapt to the humid and dusty environment of the construction site and extend its service life.

[0020] Furthermore, the terminal monitoring platform consists of computer-based monitoring software and a mobile app. The computer-based monitoring software is compatible with operating systems such as Windows and Linux, while the mobile app is compatible with Android and iOS systems. Staff can check the water pump's operating status anytime, anywhere, as detailed below: The terminal monitoring platform can display various operating parameters (liquid level, current, vibration, temperature, flow rate) and operating status (normal, dry pumping, obstruction, idling, overheating) of the water pump in real time, and accurately receive abnormal alarm information. The abnormal alarm information includes the type of abnormality, the time of occurrence, the water pump number, and the specific location on site (latitude and longitude positioning), which facilitates the staff to quickly locate the faulty water pump and handle it in a timely manner. The staff can remotely issue control commands such as shutdown, restart, and main / standby pump switching through the terminal monitoring platform. The command transmission delay is ≤1 second, and some faults can be handled without going to the site, improving the efficiency of fault handling. At the same time, the staff can query the historical operating data and fault records of the water pump. Historical data can be stored for more than 1 year, which is convenient for fault tracing and equipment maintenance. The terminal monitoring platform also has data statistical analysis functions, which can automatically generate water pump operation reports and fault statistics reports (daily, weekly, and monthly reports), which intuitively present the equipment operating status and maintenance status, and provide decision-making basis for construction site equipment management. In addition, the terminal monitoring platform supports multi-user permission management, which can assign different operation permissions according to the responsibilities of the staff to ensure the security of system operation.

[0021] Furthermore, the system also includes an emergency backup power module, which is electrically connected to each functional module of the system. This module provides emergency power to the detection, control, and communication modules in the event of a sudden power outage at the construction site, ensuring the normal operation of each core module, timely sending power outage alarm information, and fully recording the water pump operating status before the power outage to prevent loss of abnormal information and untraceable faults. The emergency backup power module uses a 12V high-capacity lithium battery pack with a capacity ≥10000mAh and features automatic charging. It can automatically replenish power during normal power supply (AC220V) with a charging time ≤8 hours, ensuring the reliability and continuity of emergency power supply, and providing emergency power for ≥4 hours. The emergency backup power module also has a power monitoring unit that monitors the battery level in real time. When the power level falls below a preset threshold (20%), it pushes a low-power reminder to the terminal monitoring platform, facilitating timely replacement or charging by staff. This module adopts a waterproof and shockproof structure, adaptable to the complex installation environment of the construction site.

[0022] Furthermore, the probe surface of the anti-clogging level sensor is coated with an anti-debris adhesion coating, which can effectively prevent mud, sand, and debris in construction site sewage from clogging the probe and ensuring the accuracy of level detection; the waterproof vibration sensor adopts a fully sealed waterproof structure, which can adapt to the harsh environment of humid and dusty construction sites, extend the service life of the sensor, and ensure the stability and accuracy of vibration data acquisition; the flow sensor is made of corrosion-resistant material, which can withstand the erosion of acid, alkali, mud, and other media in construction site sewage, avoid sensor damage, and ensure the accuracy of flow data acquisition; each sensor is equipped with a waterproof wiring connector to prevent rainwater and sewage from entering the sensor and causing short circuit damage.

[0023] This invention also discloses an intelligent control method for construction site water pumps based on the above system, comprising the following steps: S1: System initialization. The control module loads preset thresholds and control logic. The detection module, execution module, communication module, and terminal monitoring platform simultaneously enter the working state. Staff can set or adjust preset thresholds and control logic through the terminal monitoring platform according to the actual working conditions of the construction site. At the same time, the emergency backup power supply module completes self-test to ensure that the emergency power supply function is normal. The communication module completes the connection with the terminal monitoring platform to confirm smooth communication. The control module performs initialization tests on each module. If an abnormality is detected in a module, module fault information is immediately generated and pushed to the terminal monitoring platform.

[0024] S2: The detection module collects real-time data on the water pump's level, current, vibration, temperature, and flow rate at a preset sampling frequency (1-5 seconds / time). After filtering and calibration by the data processing unit, the data is transmitted to the logic judgment unit of the control module. The sampling frequency can be flexibly adjusted according to actual needs to ensure timely capture of abnormal data. The detection module performs a self-check every time it collects a set of data. If an abnormal data is detected (such as data mutation or data loss), it immediately sends a data abnormality alert to the control module.

[0025] S3: The logic judgment unit compares and analyzes the processed accurate data with preset thresholds to comprehensively determine whether the water pump is in abnormal operating conditions such as dry running, debris jamming, idling, or overheating, avoiding misjudgments caused by a single data point. If an abnormal data alert is detected, the logic judgment unit prioritizes determining that the detection module is faulty, generates fault information and pushes it to the terminal monitoring platform, while maintaining the current operating status of the water pump to avoid accidental shutdown. If multiple abnormal operating conditions are detected, the most urgent condition is prioritized (e.g., overheating takes precedence over dry running).

[0026] S4: If the condition is determined to be normal, the control module continuously receives data transmitted by the detection module to maintain the normal operation of the water pump, and pushes the real-time operating status data to the terminal monitoring platform through the communication module for staff to view in real time; at the same time, the control module records the water pump operating data to form a historical operating ledger, providing support for subsequent data statistical analysis; the emergency backup power module is continuously charging to ensure emergency power supply capability.

[0027] S5: If an abnormal operating condition is detected, the control module immediately generates a shutdown control signal and sends it to the execution module. The execution module quickly cuts off the power supply to the water pump, achieving emergency shutdown protection. At the same time, the control module generates abnormal information and pushes it to the terminal monitoring platform through the communication module, triggering multiple forms of alarms such as audible alarms and pop-up alarms to remind staff to pay attention in a timely manner. If multiple abnormal operating conditions are detected at the same time, the control module prioritizes triggering the most urgent shutdown protection command and clearly marks all abnormal types in the abnormal information. The control module synchronously records the time of occurrence of the abnormality and the abnormal data to form a fault record for easy subsequent traceability.

[0028] S6: Staff can view abnormal information through the terminal monitoring platform, determine the operability of the fault based on the type of abnormality, and if the fault can be resolved remotely (e.g., slight dry pumping, which can be addressed by remotely opening the inlet valve to replenish the water source), a restart signal is sent, the execution module connects the water pump power supply, and the water pump is restarted; if the fault cannot be resolved remotely (e.g., obstruction by debris, pump body damage), staff are arranged to handle the situation on-site. After the handling is completed, a restart signal is sent through the terminal monitoring platform to restore the water pump operation; if the main pump fault cannot be immediately resolved, the control module automatically sends a switching signal, the execution module switches to the standby pump, and the main pump fault status is marked on the terminal monitoring platform to remind staff to repair it in time; after the staff has handled the situation, they can enter the fault handling record on the terminal monitoring platform to complete the fault log.

[0029] S7: After the water pump resumes operation, the detection module continues to collect operating data, and the control module continuously monitors the operating conditions to form a closed-loop control, ensuring that there are no secondary abnormalities after the water pump returns to normal. If the same abnormal operating conditions are detected after restarting, the control module immediately triggers the shutdown protection again and marks "abnormality not eliminated after restart" in the abnormal information, reminding staff to investigate deeper faults. If a communication abnormality is detected, the control module starts the backup communication mode to ensure that abnormal information can be pushed normally. Beneficial effects

Precisely addressing the core pain points of unattended construction site water pumps: This invention utilizes multi-sensor collaborative data acquisition and fusion analysis to comprehensively and accurately identify various abnormal operating conditions such as dry pumping, obstruction by debris, and idling.

[0032] 3. Combining remote monitoring and remote handling improves fault handling efficiency: Through two-way communication between the communication module and the terminal monitoring platform, staff can remotely view the pump's operating status in real time, receive abnormal alarm information, and remotely issue control commands such as shutdown, restart, and main / standby pump switching. Some faults can be handled without going to the site, significantly improving fault handling efficiency, reducing construction interruption time, and ensuring construction continuity. The terminal monitoring platform's positioning function can help staff quickly locate faulty pumps, further shortening fault handling time.

[0033] 4.

Overall, it has strong adaptability and outstanding practicality, and can meet the usage needs of complex construction site scenarios.

[0034] 5. Data traceability facilitates equipment operation and maintenance optimization: The system can completely record water pump operation data, abnormal fault information and handling records. Historical data is stored for a long time, and staff can query historical data through the terminal monitoring platform, which facilitates fault tracing, equipment maintenance and operation optimization. The data analysis function of the terminal monitoring platform can automatically generate operation reports and fault statistics reports, providing decision-making basis for construction site equipment management and further reducing operation and maintenance costs.

[0035] 6. Multiple protections enhance system reliability: The system is equipped with multiple protection mechanisms, including emergency shutdown protection, overload protection, overheat protection, and emergency power supply protection. It also features fault self-diagnosis and communication anomaly switching functions, which can effectively prevent equipment failures from escalating, improve the reliability and stability of system operation, and extend the service life of equipment.

Detailed Implementation

[0038] The present invention will be further described in detail below with reference to specific embodiments. Example

[0039] A smart automatic detection and control system for construction site water pumps includes a detection module 1, a control module 2, an execution module 3, a communication module 4, a terminal monitoring platform 5, and an emergency backup power supply module 6.

[0040] The detection module 1 consists of an anti-clogging level sensor 11, a high-precision current sensor 12, a waterproof vibration sensor 13, a temperature sensor 14, and a flow sensor 15. The anti-clogging level sensor 11 is installed at the water storage area of ​​the foundation pit (12cm below the inlet of water pump 7), employing a probe-type structure with a 0.15mm thick polytetrafluoroethylene coating on the probe. Its detection accuracy is ±0.1cm, and the preset dry-pump judgment threshold is 5cm. When the water level is below 5cm, it is preliminarily determined to be in a dry-pumping condition. The high-precision current sensor 12 is installed in a through-hole configuration, connected in series to the power supply circuit of the water pump 7 motor. Its acquisition accuracy is ±1%, and the preset no-load current threshold is 40% of the motor's rated current. The normal operating current range is 70%-110% of the rated current. When the current is below 40%, it is preliminarily determined to be in a no-load condition; when the current is above 110%, it is preliminarily determined to be in an overload condition (due to debris). (Stuck) Working condition; Waterproof vibration sensor 13 is magnetically installed on the side of the pump body of water pump 7, with IP67 waterproof rating, vibration frequency detection range of 10-1000Hz, amplitude detection range of 0.01-10mm, and preset vibration threshold of 0.5mm. When the vibration amplitude exceeds 0.5mm, it is initially judged as a stuck working condition; Temperature sensor 14 is patch-mounted at the connection between the motor housing and the pump shaft, with a temperature detection range of -20℃-150℃, detection accuracy of ±0.5℃, and preset temperature protection threshold of 85℃. When the temperature exceeds 85℃, overheat protection is triggered; Flow sensor 15 adopts flange connection, adapts to pipe diameter of 100mm, flow detection range of 0.1-10m³ / h, detection accuracy of ±2%, and preset flow threshold of 30% of the rated flow of water pump 7. When the flow is below 30%, it helps to judge dry pumping and idling conditions.

[0041] Control module 2 uses an STM32F103 microcontroller, with a built-in data processing unit 22 and a logic judgment unit 23. The data processing unit 22 uses a Kalman filter algorithm and a linear calibration algorithm to filter and reduce noise and perform error calibration on the collected data, and has a 1-hour data buffer function. The logic judgment unit 23 performs comprehensive analysis on the processed data according to preset judgment logic to determine whether the operating conditions are normal: when the liquid level is <5cm and the flow rate is <30% of the rated flow rate, it is determined to be a dry pumping condition; when the current is <40% of the rated current and the flow rate is <30% of the rated flow rate and the vibration is ≤0.5mm, it is determined to be an idling condition; when the vibration is >0.5mm and the current is >110% of the rated current, it is determined to be a debris jamming condition; when the temperature is >85℃, it is determined to be an overheating condition.

10. A method for intelligent control of construction site water pumps based on the system described in any one of claims 1-9, characterized in that, Includes the following steps: S1: System initialization. The control module loads preset thresholds and control logic. The detection module, execution module, communication module, and terminal monitoring platform simultaneously enter working status. Personnel can set or adjust preset thresholds and control logic through the terminal monitoring platform according to the actual working conditions at the construction site. Simultaneously, the emergency backup power module completes self-testing to ensure normal emergency power supply function, and the communication module completes connection with the terminal monitoring platform to confirm smooth communication. The control module performs initialization tests on each module. If an abnormality is detected in any module, a module fault information is immediately generated and pushed to the terminal monitoring platform. S2: The detection module collects real-time data on the water pump's level, current, vibration, temperature, and flow rate at a preset acquisition frequency (1-5 seconds / time). After filtering using a Kalman filter algorithm and calibration using a linear calibration algorithm by the data processing unit, the data is transmitted to the logic judgment unit of the control module. The sampling frequency can be flexibly adjusted according to actual needs to ensure timely capture of abnormal data; Each time the detection module collects a set of data, it performs a self-check simultaneously. If any abnormalities such as sudden data changes or missing data are detected, it immediately sends a data anomaly alert to the control module. S3: The logic judgment unit compares and analyzes the processed accurate data with preset thresholds to comprehensively determine whether the water pump is in abnormal operating conditions such as dry running, obstruction by debris, idling, or overheating, avoiding misjudgments caused by relying on a single data source. If an abnormal data alert is detected, the logic judgment unit will first determine that the detection module is faulty, generate fault information and push it to the terminal monitoring platform, while maintaining the current operating status of the water pump to avoid accidental shutdown. If multiple abnormal operating conditions are detected, the most urgent condition is prioritized (e.g., overheating takes precedence over dry pumping). S4: If the condition is determined to be normal, the control module continuously receives data transmitted from the detection module to maintain the normal operation of the water pump. It also pushes real-time operating status data to the terminal monitoring platform via the communication module for real-time viewing by staff. Simultaneously, the control module records water pump operating data to create a historical operating log, providing support for subsequent data statistical analysis. The emergency backup power module remains in a charging state to ensure emergency power supply capability. S5: If an abnormal operating condition is detected, the control module immediately generates a shutdown control signal and sends it to the execution module. The execution module quickly cuts off the water pump power supply, achieving emergency shutdown protection. Simultaneously, the control module generates abnormal information and pushes it to the terminal monitoring platform via the communication module, triggering multiple alarms such as audible alarms and pop-up alarms to remind staff to pay attention. If multiple abnormal operating conditions are detected simultaneously, the control module prioritizes triggering the most urgent shutdown protection command (e.g., overheating takes precedence over dry pumping) and clearly marks all abnormal types in the abnormal information. S6: Staff can view abnormal information through the terminal monitoring platform, determine the operability of the fault based on the type of abnormality, and if the fault can be resolved remotely (e.g., slight dry pumping, which can be addressed by remotely opening the inlet valve to replenish the water source), a restart signal is sent, the execution module connects the water pump power supply, and the water pump is restarted; if the fault cannot be resolved remotely (e.g., obstruction by debris, pump body damage), staff are arranged to handle the situation on-site. After the handling is completed, a restart signal is sent through the terminal monitoring platform to restore the water pump operation; if the main pump fault cannot be immediately resolved, the control module automatically sends a switching signal, the execution module switches to the standby pump, and the main pump fault status is marked on the terminal monitoring platform to remind staff to repair it in time; after the staff has handled the situation, they can enter the fault handling record on the terminal monitoring platform to complete the fault log. S7: After the water pump resumes operation, the detection module continues to collect operating data, and the control module continuously monitors the operating conditions to form a closed-loop control, ensuring that there are no secondary abnormalities after the water pump returns to normal. If the same abnormal operating conditions are detected after restarting, the control module immediately triggers the shutdown protection again and marks "abnormality not eliminated after restart" in the abnormal information, reminding staff to investigate deeper faults. If a communication abnormality is detected, the control module starts the backup communication mode to ensure that abnormal information can be pushed normally.
