Description

Technical Field

[0001] This invention relates to the field of swimming pool water treatment technology, and in particular to a method and device for diagnosing multiple faults in an integrated hair collector. Background Technology

[0002] In traditional swimming pool water treatment systems, hair collectors serve as primary filtration units, primarily relying on filter screens or baskets to physically trap large particles such as hair and fibers. However, existing technologies generally suffer from the following shortcomings:

[0003] First, traditional swimming pool hair collectors mainly rely on manual periodic observation and cleaning, which has the problems of low efficiency and slow response. When too much hair and other dirt accumulates, it will increase the load on the water pump, increase energy consumption, and may even pose a safety hazard to swimmers due to excessively high vacuum.

[0004] Secondly, judging the clogging status of the filter mainly relies on manual periodic opening of the cover for inspection or estimation of running time based on experience, which results in a delayed response. It is impossible to perceive the degree of clogging in real time and accurately, which can easily lead to pump overload, increased energy consumption, or decreased filtration efficiency, affecting the subsequent disinfection effect.

[0005] Third, regarding the risk of swimmers being trapped in drainage outlets, current technologies mostly rely on physical screens for passive protection, lacking proactive monitoring and emergency shutdown mechanisms based on real-time hydraulic conditions. If the screens become accidentally blocked or malfunction, serious safety risks remain.

[0006] Fourth, especially for equipment with integrated disinfection functions, the core ultraviolet disinfection module often requires professional personnel to perform tedious disassembly and chemical cleaning after scaling or contamination. This results in long maintenance cycles, high costs, and may affect the continuity and reliability of disinfection. Furthermore, some existing monitoring solutions may only have a single pressure or flow sensor. When system performance deteriorates, they can only issue a general alarm of "system abnormality" and cannot accurately distinguish whether the problem is a blockage in the pre-filter, obstruction in the flow channel of the disinfection unit, or failure of the ultraviolet lamp, which makes maintenance difficult. Summary of the Invention

[0007] In view of this, the present invention provides a solution that integrates filtration, disinfection, safety monitoring, and intelligent diagnostics, enabling real-time perception of operational status, accurate differentiation of various faults, proactive risk prevention, and convenient maintenance. The technical solution adopted in this application is as follows:

[0008] A multi-fault diagnosis method for an integrated hair gatherer includes the following steps:

[0009] S1: Real-time collection of the first negative pressure P1 at the inlet of the hair collector, the second negative pressure P2 at the outlet of the hair filtration section, the third negative pressure P3 at the inlet of the ultraviolet disinfection section, and the fourth negative pressure P4 at the outlet of the ultraviolet disinfection section.

[0010] S2: Based on the currently collected first negative pressure P1, second negative pressure P2, third negative pressure P3 and fourth negative pressure P4, calculate the filtration pressure drop ΔP1 and disinfection pressure drop ΔP2 respectively;

[0011] S3: Determine if there is an adsorption risk. The adsorption risk determination condition is based on whether the instantaneous value of the first negative pressure P1 is less than the safe adsorption threshold Py1. If it is less than Py1, an adsorption risk is determined, and the highest emergency response is triggered. If it is not less than Py1, multiple fault diagnosis is performed. Specifically, based on the different results of the multiple fault diagnosis, corresponding fault diagnosis codes are output, and differentiated automatic responses or maintenance prompts are executed. The specific steps for performing multiple fault diagnosis include:

[0012] S30: Obtain the first cleaning baseline value ΔP1 for the filter pressure drop ΔP1. c The second cleaning baseline value ΔP2 is related to the disinfection pressure drop ΔP2. c ;

[0013] S31: Based on the filter pressure drop ΔP1 and the first cleaning reference value ΔP1 c The ratio relationship is used to determine whether the hair filtration section is clogged;

[0014] S32: If the hair filtration section is not clogged, then based on the disinfection pressure drop ΔP2 and the second cleaning reference value ΔP2 c The ratio relationship can be used to determine whether the ultraviolet disinfection section is blocked;

[0015] S33: If the hair filtration section and the ultraviolet disinfection section are not blocked, the efficiency of the ultraviolet lamp is determined based on the radiation intensity monitoring value of the ultraviolet disinfection section.

[0016] Preferably, the calculation formulas for the filtration pressure drop ΔP1 and the disinfection pressure drop ΔP2 are as follows: The steps for triggering the highest emergency response include: sending the highest level shutdown command to the circulating water pump, activating the on-site alarm, and locking the system to a safe state until manually reset.

[0017] Preferably, in step S31, the condition for determining that the hair filter segment is clogged is:

[0018] ;

[0019] Wherein, K1 is the first proportional coefficient greater than 1; when the condition is met, the system triggers a filter blockage alarm, outputs the first fault diagnosis code, and executes an enhanced backwashing procedure or prompts for manual cleaning of the filter cartridge.

[0020] Preferably, in step S32, the condition for determining that the ultraviolet disinfection section is blocked is:

[0021] ;

[0022] Wherein, K2 is a second proportional coefficient greater than 1; when the condition is met, the system triggers a disinfection section blockage alarm, outputs a second fault diagnosis code, and automatically executes the built-in physical cleaning program of the ultraviolet disinfection section.

[0023] Preferably, in step S33, the condition for determining that the efficiency of the ultraviolet lamp tube has decreased is: the real-time monitored ultraviolet radiation intensity value is lower than the preset percentage threshold of the rated intensity. When the condition is met, the system triggers a lamp tube maintenance alarm and outputs a third fault diagnosis code.

[0024] Preferably, the present invention also provides an integrated hair aggregator multi-fault diagnosis device, applied to the above-described integrated hair aggregator multi-fault diagnosis method, comprising a data acquisition module for real-time acquisition of the first negative pressure P1, the second negative pressure P2, the third negative pressure P3, and the fourth negative pressure P4; a data processing and diagnosis module for calculating the filtration pressure drop ΔP1 and the disinfection pressure drop ΔP2, and performing the adsorption risk judgment and multi-fault diagnosis; a control execution module for controlling the start-up and shutdown of the circulating water pump, the alarm, the drain valve, and the ultraviolet disinfection section cleaning mechanism according to the output instructions of the data processing and diagnosis module; and a human-machine interaction module for displaying the fault diagnosis code and the system operating status, and receiving manual instructions.

[0025] Preferably, the data acquisition module includes a first negative pressure sensor, a second negative pressure sensor, a third negative pressure sensor, and a fourth negative pressure sensor respectively installed at the inlet of the hair collector, the outlet of the hair filtration section, the inlet of the ultraviolet disinfection section, and the outlet of the ultraviolet disinfection section, as well as a radiation intensity sensor installed in the ultraviolet disinfection section; the data processing and diagnostic module is a logic controller or an embedded microcontroller, which internally stores the safe adsorption threshold Py1 and the first cleaning reference value ΔP1. c Second cleaning baseline value ΔP2 c The first proportionality coefficient K1 and the second proportionality coefficient K2.

[0026] Preferably, the ultraviolet disinfection section cleaning mechanism includes a detachable disinfection module. The disinfection module has a first inlet and a first outlet at each end. The first inlet is detachably connected to the hair filtration section outlet, and the first outlet is connected to the ultraviolet disinfection section outlet. The disinfection module includes a sealed housing. Inside the sealed housing are multiple parallel thin branch tubes. Each thin branch tube is connected to the first inlet and the first outlet at both ends. An ultraviolet lamp is also installed in the center of the multiple thin branch tubes. The ultraviolet lamp is fixedly installed inside the sealed housing. Each thin branch tube is also equipped with a corresponding cleaning component. The cleaning component includes a scraping element, a linkage rod connected to the scraping element, and a drive motor that drives the linkage rod to reciprocate along the axial direction of the thin branch tube. The drive motor is signal-connected to the control execution module, receives cleaning commands, and drives the scraping element to scrape away the deposits on the inner wall of the thin branch tube.

[0027] Preferably, each thin branch tube also has a transparent section, and the transparent section is located around the light-emitting part of the ultraviolet lamp tube, and each ultraviolet lamp tube is also connected to the radiation intensity sensor signal.

[0028] Preferably, the human-machine interaction module includes: a display screen, status indicator lights, and operation buttons. The display screen is used to dynamically display the values ​​of the first negative pressure P1, the second negative pressure P2, the third negative pressure P3, and the fourth negative pressure P4 in real time, as well as the currently diagnosed fault diagnosis code and the corresponding text maintenance instructions. The status indicator lights are used to indicate the system operating status and alarm level. The operation buttons are used to perform alarm confirmation, parameter viewing, and manual reset operations.

[0029] Beneficial effects: Compared with the prior art, the integrated hair gatherer multi-fault diagnosis method and device provided by the present invention has the following significant beneficial effects:

[0030] First, the solution of this invention achieves accurate diagnosis and intelligent differentiation of multi-level faults, greatly improving operation and maintenance efficiency and targeting. Traditional solutions can only provide general alarms, while this invention, through the coordinated layout of four negative pressure sensors, can accurately distinguish and locate core faults. For example, it determines the adsorption safety risk by instantaneously exceeding the first negative pressure P1, triggering the highest priority response; and it compares the filtration pressure drop ΔP1 with the first cleaning baseline value ΔP1. c The comparison determined that the hair filtration section was clogged; the disinfection pressure drop ΔP2 was compared with the second cleaning baseline value ΔP2. c By comparing the results, it was determined that the internal flow channels of the ultraviolet disinfection section were blocked. This enabled maintenance personnel to take targeted measures quickly based on the clear fault codes, avoiding blind troubleshooting and greatly shortening the fault location and response time.

[0031] Secondly, this invention also addresses the pain point of reduced light transmittance in ultraviolet disinfection units due to scale and biofilm buildup causing channel blockage. The invention employs a disinfection module with integrated built-in cleaning components that can be plugged in and removed as a whole. When a blockage is detected in the disinfection section (ΔP2 exceeding the standard), the control module automatically initiates the cleaning program. The drive motor moves the linkage rod and all scraping elements reciprocating within the narrow branch tube, scraping away dirt and restoring channel flow and light transmittance. Simultaneously, the modular, quick-release design reduces the traditionally time-consuming professional cleaning process (several hours) to less than ten minutes of manual operation, lowering maintenance costs.

Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Example 1:

[0042] See Figures 1-4 A multi-fault diagnosis method for an integrated hair gatherer includes the following steps:

[0043] S1: Real-time collection of the first negative pressure P1 at the inlet of the hair collector 5, the second negative pressure P2 at the outlet of the hair filtration section 50, the third negative pressure P3 at the inlet of the ultraviolet disinfection section 51, and the fourth negative pressure P4 at the outlet of the ultraviolet disinfection section 51.

[0044] S2: Based on the currently collected first negative pressure P1, second negative pressure P2, third negative pressure P3 and fourth negative pressure P4, calculate the filtration pressure drop ΔP1 and disinfection pressure drop ΔP2 respectively;

[0045] S3: Determine if there is an adsorption risk. The adsorption risk determination condition is based on whether the instantaneous value of the first negative pressure P1 is less than the safe adsorption threshold Py1. If it is less than Py1, an adsorption risk is determined, and the highest emergency response is triggered. If it is not less than Py1, multiple fault diagnosis is performed. Specifically, based on the different results of the multiple fault diagnosis, corresponding fault diagnosis codes are output, and differentiated automatic responses or maintenance prompts are executed. The specific steps for performing multiple fault diagnosis include:

[0046] S30: Obtain the first cleaning baseline value ΔP1 for the filter pressure drop ΔP1. c The second cleaning baseline value ΔP2 is related to the disinfection pressure drop ΔP2. c ;

[0047] S31: Based on the filter pressure drop ΔP1 and the first cleaning reference value ΔP1 c The ratio relationship is used to determine whether the hair filter section 50 is clogged;

[0048] S32: If the hair filtration section 50 is not clogged, then based on the disinfection pressure drop ΔP2 and the second cleaning reference value ΔP2 c The ratio relationship is used to determine whether the ultraviolet disinfection section 51 is blocked;

[0049] S33: If the hair filtration section and the ultraviolet disinfection section are not blocked, the efficiency of the ultraviolet lamp is judged based on the radiation intensity monitoring value of the ultraviolet disinfection section 51.

[0050] Specific process:

[0051] Scenario 1: If the corresponding adsorption risk is triggered: When the data processing and diagnosis module 2 reads the pressure value P1 from the first negative pressure sensor 9 in real time and detects that its instantaneous value exceeds the preset safe adsorption threshold Py1 (e.g., -0.06 MPa), it immediately determines an emergency adsorption risk. The control execution module 3 then executes the following uninterrupted sequence:

[0052] 1. Send a hard-wired "emergency stop" signal to the control circuit of the swimming pool circulating water pump 6, forcing the circulating water pump 6 to stop operating within 0.5 seconds;

[0053] 2. Simultaneously activate the alarms installed at the equipment site and in the control room, emitting a sharp alarm sound and flashing red light;

[0054] 3. Lock the entire system's control status to "Safe Shutdown," suspending all automatic programs. This lock can only be released by authorized personnel performing a manual reset operation on the human-machine interface module 4, thereby ensuring that risks are completely eliminated.

[0055] Scenario 2, Corresponding Filter Clogging Diagnosis and Response: When the system is operating normally and there is no risk of adsorption, the data processing and diagnosis module 2 continuously calculates the filter pressure drop ΔP1 (P1-P2). It internally stores the baseline value ΔP1 of the device in a clean state. c If the average value of ΔP1 over 30 consecutive seconds satisfies the condition: ΔP1 > K1 × ΔP1 c When K1=2.5, the diagnosis is blockage of hair filter segment 50. The system triggers the following response:

[0056] 1. The "First Fault Diagnosis Code: F01" will pop up on the display screen of the human-machine interaction module 4, and the maintenance guide "Filter cartridge clogged, cleaning recommended" will be displayed.

[0057] 2. Simultaneously, through the control execution module 3, during the next preset low-load operating period (such as 2:00 AM), an "enhanced backwashing program" is automatically initiated: first, the circulating water pump 6 is shut off, then the drain valve 7 is fully opened for 60 seconds (30 seconds longer than regular flushing), using the system's residual pressure and gravity to powerfully flush the filter cartridge. After completion, operation is automatically resumed, and ΔP1 is reassessed.

[0058] In some embodiments, the calculation formulas for the filtration pressure drop ΔP1 and the disinfection pressure drop ΔP2 are respectively... The steps for triggering the highest emergency response include: sending the highest level shutdown command to the circulating water pump 6, activating the on-site alarm, and locking the system to a safe state until manually reset.

[0059] In some embodiments, the condition for determining that the hair filter section 50 is clogged in step S31 is:

[0060] ;

[0061] Wherein, K1 is the first proportional coefficient greater than 1; when the condition is met, the system triggers a filter blockage alarm, outputs the first fault diagnosis code, and executes an enhanced backwashing procedure or prompts for manual cleaning of the filter cartridge.

[0062] In some embodiments, the condition for determining that the ultraviolet disinfection section 51 is blocked in step S32 is:

[0063] ;

[0064] Wherein, K2 is a second proportional coefficient greater than 1; when the condition is met, the system triggers a blockage alarm in the disinfection section, outputs a second fault diagnosis code, and automatically executes the built-in physical cleaning program of the ultraviolet disinfection section 51.

[0065] If the filtration pressure drop ΔP1 is normal, the system calculates and evaluates the disinfection pressure drop ΔP2 (P3-P4). The system is considered effective when the average value of ΔP2 over 60 consecutive seconds meets the condition: ΔP2 > K2 × ΔP2. c When K2=3.0, the system diagnoses a blockage in the internal flow channel of the UV disinfection section 51. The system triggers the following automatic response:

[0066] 1. Displays "Second fault diagnosis code: U01";

[0067] 2. The control execution module 3 sends a cleaning command to the drive motor 8062 within the disinfection module 80. The drive motor 8062 starts, driving the scraping element 8060 within the thin branch tube 804 via the linkage rod 8061, moving it from one end of the thin branch tube 804 to the other (approximately 3 seconds), and then reversing to reset (another 3 seconds). This reciprocating motion effectively scrapes away scale and biofilm adhering to the inner wall of the transparent section 8040. After cleaning, the system waits for the water flow to stabilize for 2 minutes and then reads ΔP2 again. If the value returns to normal, the alarm is cleared; if it remains high, the alarm is upgraded to "U02: Manual check of the disinfection module required".

[0068] In some embodiments, in step S33, the condition for determining that the efficiency of the ultraviolet lamp 805 has decreased is: the real-time monitored ultraviolet radiation intensity value is lower than the preset percentage threshold of the rated intensity. When the condition is met, the system triggers an ultraviolet lamp maintenance alarm and outputs a third fault diagnosis code.

[0069] When the radiation intensity sensor 13 monitors the ultraviolet intensity transmitted through the transparent section 8040 of the thin branch tube 804 in real time, the data processing and diagnostic module 2 compares this intensity value with the rated output intensity of the ultraviolet lamp tube 805. If the monitored intensity value remains below 70% of the rated value for more than 1 hour, and ΔP1 and ΔP2 are normal at this time, it is determined that the ultraviolet lamp tube 805 is experiencing performance degradation or the thin branch tube 804 is severely contaminated. The system triggers "Third Fault Diagnosis Code: L01" and displays "Insufficient ultraviolet intensity, please check or replace the lamp tube" on the screen. This monitoring provides crucial data for predictive maintenance, avoiding the risk of disinfection effects failing unnoticed.

[0070] Example 2:

[0071] See Figures 3-6 The present invention also provides an integrated hair aggregator multi-fault diagnosis device, applied to the aforementioned integrated hair aggregator multi-fault diagnosis method, comprising a data acquisition module 1 for real-time acquisition of the first negative pressure P1, the second negative pressure P2, the third negative pressure P3, and the fourth negative pressure P4; a data processing and diagnosis module 2 for calculating the filtration pressure drop ΔP1 and the disinfection pressure drop ΔP2, and executing the adsorption risk judgment and multi-fault diagnosis logic; a control execution module 3 for controlling the start-up and shutdown of the circulating water pump 6, the alarm, the drain valve 7, and the ultraviolet disinfection section cleaning mechanism 8 according to the output instructions of the data processing and diagnosis module 2; and a human-machine interaction module 4 for displaying the fault diagnosis code and the system operating status, and receiving manual instructions.

[0072] Traditional hair collectors are merely passive filtration containers. This device, however, organically integrates a data acquisition module 1, a data processing and diagnostic module 2 (such as a PLC / microcontroller), a control execution module 3, and a human-machine interaction module 4, constructing a complete closed loop of perception, analysis, decision-making, execution, and interaction. This transforms it from a simple mechanical component into an intelligent front-end processing unit capable of autonomous judgment and proactive intervention, completely eliminating reliance on manual experience and periodic inspections. Furthermore, the filtration pressure drop ΔP1 and disinfection pressure drop ΔP2 can accurately distinguish whether a fault occurs in the hair filtration section 50 or the internal flow channel of the ultraviolet disinfection section 51. The control execution module 3 can then execute differentiated automatic programs accordingly: for filter blockage, it performs timed enhanced backwashing (controlling the drain valve 7); for disinfection section blockage, it drives the ultraviolet disinfection section cleaning mechanism 8 to automatically scrape and clean. This targeted, automated processing avoids misjudgments and ineffective operations. The system's operating status mainly includes operating modes, such as normal operation, safe shutdown (e.g., locking after triggering adsorption risk), and maintenance modes (e.g., performing backwashing and automatic cleaning), as well as real-time values ​​of key parameters and equipment status information.

[0073] In some embodiments, the data acquisition module 1 includes a first negative pressure sensor 9, a second negative pressure sensor 10, a third negative pressure sensor 11, and a fourth negative pressure sensor 12 respectively installed at the inlet of the hair collector 5, the outlet of the hair filtration section 50, the inlet of the ultraviolet disinfection section 51, and the outlet of the ultraviolet disinfection section 51, as well as a radiation intensity sensor 13 installed in the ultraviolet disinfection section 51; the data processing and diagnostic module 2 is a logic controller or an embedded microcontroller, which internally stores the safe adsorption threshold Py1 and the first cleaning reference value ΔP1. c Second cleaning baseline value ΔP2 c The first proportionality coefficient K1 and the second proportionality coefficient K2.

[0074] In some embodiments, the ultraviolet disinfection section cleaning mechanism 8 includes a detachable disinfection module 80. The disinfection module 80 has a first inlet 801 and a first outlet 802 at its two ends. The first inlet 801 is detachably connected to the outlet of the hair filtration section 50, and the first outlet 802 is connected to the outlet of the ultraviolet disinfection section 51. The disinfection module 80 includes a sealed housing 803. Inside the sealed housing 803 are multiple parallel thin branch tubes 804. Both ends of each thin branch tube 804 are connected to the first inlet 801 and the first outlet 802, respectively. A central ultraviolet lamp tube 805 is also provided. The ultraviolet lamp tube 805 is fixedly installed in the sealed housing 803. Each thin branch tube 804 is also provided with a corresponding cleaning component 806. The cleaning component 806 includes a scraping element 8060, a linkage rod 8061 connected to the scraping element 8060, and a drive motor 8062 that drives the linkage rod 8061 to reciprocate along the axial direction of the thin branch tube 804. The drive motor 8062 is signal-connected to the control execution module 3, receives cleaning instructions, and drives the scraping element 8060 to scrape off the deposits on the inner wall of the thin branch tube 804.

[0075] In some embodiments, each thin branch tube 804 also has a transparent section 8040, and the transparent section 8040 is located around the light-emitting part of the ultraviolet lamp tube 805, and each ultraviolet lamp tube 805 is also connected to the radiation intensity sensor 13.

[0076] In some embodiments, the human-machine interaction module 5 includes: a display screen, status indicator lights, and operation buttons. The display screen is used to dynamically display the values ​​of the first negative pressure P1, the second negative pressure P2, the third negative pressure P3, and the fourth negative pressure P4 in real time, as well as the currently diagnosed fault diagnosis code and the corresponding text maintenance instructions. The status indicator lights are used to indicate the system operating status and alarm level. The operation buttons are used to perform alarm confirmation, parameter viewing, and manual reset operations.

[0077] The specific implementation process of this invention is as follows:

[0078] Installation: Press the hair gatherer 5. Figure 4 As shown, the device is installed in the pool circulation pipeline, ensuring that the inlet, hair filter section 50, ultraviolet disinfection section 51, and outlet are connected in sequence. The signal lines of the first negative pressure sensor 9, the second negative pressure sensor 10, the third negative pressure sensor 11, the fourth negative pressure sensor 12, the radiation intensity sensor 13, the circulating water pump 6, the drain valve 7, the drive motor 8062, and the alarm are correctly connected to the data processing and diagnostic module 2 and the control execution module 3.

[0079] Obtaining the Cleaning Baseline Value: After the equipment is completely cleaned, start the system and ensure the circulating water pump 6 is running normally. Enter the baseline learning mode via the human-machine interface module 4. The system automatically records and stores the stable filtration pressure drop ΔP1 at this time as the first cleaning baseline value ΔP1. c Simultaneously, a stable disinfection pressure drop ΔP2 was recorded as the second cleaning baseline value ΔP2. c Record the reading of the radiation intensity sensor 13 at this time as the rated intensity reference.

[0080] Parameter settings: By using the buttons on the human-computer interaction module 4, set the safe adsorption threshold Py1 = -0.06 MPa, the first proportional coefficient K1 = 2.5, the second proportional coefficient K2 = 3.0, and the intensity failure threshold of the 805 UV lamp tube 70%.

[0081] Multiple fault diagnosis:

[0082] Step A: Data acquisition and calculation. Simultaneously read the values ​​P1, P2, P3, and P4 from the first negative pressure sensor 9, the second negative pressure sensor 10, the third negative pressure sensor 11, and the fourth negative pressure sensor 12 at a frequency of 10 times per second. Calculate in real time: ΔP1 = P1 - P2, ΔP2 = P3 - P4.

[0083] Step B: Determine the highest priority for adsorption risk; condition judgment: Check if the instantaneous value of P1 is... <Py1 (-0.06MPa)。

[0084] Response (Scenario 1): If satisfied, the control execution module 3 immediately sends an emergency stop hard-wired command to the circulating water pump 6, causing the pump to stop. The on-site alarm is triggered, emitting an audible and visual alarm. The display screen of the human-machine interface module 4 shows "Emergency: Adsorption Risk! System Locked." The system enters a safety lock state, which can only be released by maintenance personnel pressing the "Manual Reset" button on the human-machine interface module 4.

[0085] Step C: Multiple fault diagnosis (if step B is not triggered).

[0086] Diagnostic Branch 1: Determine if hair filtration segment 50 is clogged. Conditional judgment: Calculate the average value of ΔP1 over the past 30 seconds and determine if ΔP1 > K1 × ΔP1. c .

[0087] Response (Scenario 2): If satisfied, display "Fault Code: F01 - Filter Section Clogged, Cleaning Recommended" on the HMI module 4 screen and illuminate the yellow warning light. Record the event log. The controller sets a timed task to automatically execute the "Enhanced Backwashing Program" during a preset off-peak period (e.g., 2:00 AM the next day): Control execution module 3 first stops the circulating water pump 6. Then, it opens the drain valve 7 for 60 seconds. Finally, it closes the drain valve 7 and restarts the circulating water pump 6.

[0088] The program is complete, and the warning light goes out.

[0089] Diagnostic Branch Two: Determine if the ultraviolet disinfection section 51 is blocked.

[0090] Premise: ΔP1 is not exceeded (i.e., the filtering section is normal). Condition judgment: Calculate the average value of ΔP2 over the past 60 seconds and determine whether ΔP2 > K2 × ΔP2. c .

[0091] Response (Scenario 3): If satisfied, the display shows "Fault Code: U01 - Disinfection Section Flow Channel Blockage, Automatic Cleaning Started," and the orange warning light illuminates. Control Execution Module 3 immediately sends a command to the drive motor 8062 within the disinfection module 80. Automatic cleaning procedure execution: Drive motor 8062 rotates forward, driving all scraping elements 8060 via linkage rod 8061, moving them from the inlet end of the narrow branch pipe 804 to the outlet end (approximately 3 seconds). After a brief pause, drive motor 8062 reverses, driving the scraping elements 8060 back to their original position (approximately 3 seconds). After cleaning, the system waits 120 seconds for water flow to stabilize, then reassesses ΔP2. If ΔP2 returns to normal (≤K2×ΔP2), the system will proceed as scheduled. c If the threshold is reached, the U01 alarm will be cleared. If the threshold is still exceeded, the alarm will be upgraded to "U02 - Severe blockage, manual check of disinfection module required", and the red warning light will illuminate.

[0092] Diagnostic Branch 3: Determining the effectiveness of ultraviolet lamps.

[0093] Prerequisite: Both ΔP1 and ΔP2 are normal. Condition Judgment: Read the data from radiation intensity sensor 13 and calculate its percentage relative to the rated intensity benchmark. Response (Case 4): If this percentage remains <70% for 1 hour, then: the display shows "Maintenance Code: L01 - Insufficient UV Intensity, Please Check or Replace the Lamp". The blue maintenance indicator light illuminates. This is only a reminder and does not interrupt system operation; maintenance personnel should perform planned maintenance based on the reminder.

[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
