Description

TECHNICAL FIELD

[0001] The present application relates to the field of sterilization pot, more particularly, to a sterilization pot adaptive water replenishment control method, system and medium based on water level monitoring. BACKGROUND

[0002] In the scenarios of medical sterilization, laboratory instrument processing and food industry, the safety and automation level of high-pressure steam sterilization pot as the core equipment directly relate to public health safety and equipment operation efficiency. However, the traditional system only starts water replenishment when detecting that the water level is lower than the preset static threshold, which cannot adapt to the change of water consumption rate caused by different loads and long-period operation, and often appears problems of water replenishment lag or excessive water replenishment. Among them, water replenishment lag causes dry burning risk, and excessive water replenishment causes cold water to rush in to cause temperature drop, forcing the sterilization program to be interrupted or restarted, which seriously violates the requirement of sterilization rules on temperature stability. Secondly, in the prior art, the operator often needs to manually adjust the threshold value according to experience, and frequent misjudgments often occur when dealing with high-variability loads, such as alternating sterilization of surgical instrument packages and liquid bottles, and thus accidents of sterilization interruption or equipment failure caused by improper water level control often occur. In addition, most devices only cut off the heating when detecting complete water shortage, but the residual temperature of the cavity caused by thermal inertia may still cause dry burning; without prompt or operation restriction, secondary accidents are easily caused.

[0003] The above defects commonly cause problems of shortened equipment life, decreased sterilization qualification rate and high labor cost. Therefore, there is an urgent need for an adaptive water level control technology that integrates dynamic threshold prediction, hierarchical water replenishment control and closed-loop learning optimization. SUMMARY

[0004] In view of the above problems, the purpose of the present application is to provide a sterilization pot adaptive water replenishment control method, system and medium based on water level monitoring. First, a three-level threshold hierarchical control logic is included to build a cascading response water replenishment mechanism through a protection water level threshold, a forced water level threshold and a dynamic water level threshold. Second, an adaptive water replenishment strategy is included, which starts full water replenishment if the water level is lower than the forced water level threshold, and simultaneously monitors the water level rising rate to prevent overflow. If the water level is between the dynamic water level threshold and the forced water level threshold, then the PWM signal of pulse water replenishment is regulated based on the real-time water level and the target water level deviation value. Then, a closed-loop safety protection mechanism is included, which cuts off the heating, sounds and light alarms and emergency cooling when dry burning protection is triggered. In addition, the water consumption database is updated after each cycle, and the algorithm parameters are optimized in association with the load weight and temperature fluctuation data. Through dynamic threshold prediction, hierarchical water replenishment control and data-driven iteration, the present application significantly reduces the dry burning risk and improves the adaptability of the equipment under high-variability load conditions.

[0073] Figure 1 A flow chart of a sterilization pot adaptive water replenishment control method based on water level monitoring is shown.

[0074] As Figure 1 indicated, the application aspect discloses a sterilization pot adaptive water replenishment control method based on water level monitoring, the method comprising:

[0075] S102, reading a historical water consumption database to obtain a dynamic water level threshold based on a preset threshold model;

[0076] S104, obtaining water level information;

[0077] S106, determining whether the water level information is lower than a preset protection water level threshold;

[0078] S108, if yes, cutting off the heating power supply based on a preset dry burning protection mechanism;

[0079] S110, if no, determining whether the water level information is lower than a preset forced water level threshold;

[0080] S112, if yes, controlling the water replenishment rate based on a preset full-amount water replenishment mechanism until the water level information rises to the dynamic water level threshold;

[0081] S114, if no, determining whether the water level information is lower than the dynamic water level threshold;

[0082] S116, if yes, controlling the water replenishment rate according to the deviation between the water level information and target water level information based on a preset pulse water replenishment mechanism;

[0083] S118, updating the historical water consumption database based on the water replenishment record after the sterilization cycle ends.

[0084] It should be noted that the water level information is the water level in the heating tank of the sterilization pot; the historical water consumption database includes water replenishment records in multiple sterilization cycles; and the water replenishment record at least includes water consumption and pulse parameters.

[0085] The embodiment provides a sterilization pot adaptive water replenishment control process based on water level monitoring. After the sterilization pot system is started, a historical water consumption database is first read, the database stores water replenishment records of past sterilization cycles, including water consumption, pulse parameters and the like. A dynamic water level threshold is generated based on a preset threshold model; wherein the dynamic water level threshold is floating in real time with the historical water consumption mode and is always higher than the forced water level threshold and the protection water level threshold. Then, the real-time water level information in the heating water tank of the sterilization pot is continuously obtained through the water level sensor, and a three-level linked judgment mechanism is executed. First, whether the water level is lower than the protection water level threshold is compared. If it is lower than the protection water level threshold, the heating power is immediately cut off and the dry burning protection mechanism is activated to prevent the equipment from being damaged by empty burning; if it is not lower than the protection water level threshold, whether the water level is lower than the forced water level threshold is further judged. If it is lower than the forced water level threshold, the full-amount water replenishment mechanism is started to replenish water at a constant standard rate until the water level rises to the forced water level threshold. If the water level is between the dynamic water level threshold and the forced water level threshold, the pulse water replenishment mechanism is enabled, the pulse period is dynamically adjusted according to the deviation value of the real-time water level and the target water level, and intermittent water replenishment is adopted to avoid temperature drop. As an implementation mode, high-frequency long pulses are used when the water level deviation is large, and low-frequency short pulses are used when the water level deviation is small. Finally, at the end of the sterilization cycle, the total water amount, pulse number and other data of this time water replenishment are automatically summarized and updated to the historical water consumption database to form a closed loop optimization. Through the three-level threshold linkage response and closed loop data update, the embodiment realizes adaptive water replenishment under unattended condition, completely eliminates the dry burning risk and improves the sterilization continuity.

[0086] Figure 2 A flowchart for generating a dynamic water level threshold provided by the embodiment of the application is shown.

[0087] According to the embodiment of the application, as shown in Figure 2 The reading of the historical water consumption database, based on the preset threshold model, obtains a dynamic water level threshold, specifically including:

[0088] S202, extracting the average water consumption rate of at least two recent sterilization cycles in the historical water consumption database;

[0089] S204, calculating a dynamic offset according to the average water consumption rate and combining the length of the current sterilization stage;

[0090] S206, obtaining a safety coefficient based on a preset coefficient mapping table according to the sterilization load type;

[0091] S208, superimposing the forced water level threshold and the dynamic offset, combining the safety coefficient, and generating a real-time updated dynamic water level threshold.

[0092] It should be noted that the embodiment provides a generation process of a dynamic water level threshold. First, the average water consumption rate data of at least two recent sterilization cycles is extracted from the historical water consumption database, and the rate reflects the water consumption law of the device under typical load. Combined with the running time of the current sterilization stage, the dynamic offset is calculated, wherein the calculation logic is that the longer the running time is, the higher the risk of water level drop is. Then, according to the load type in the sterilization pot, such as porous instruments, liquid bottles and the like, the preset coefficient mapping table is queried to determine the adaptive safety coefficient. Finally, the forced water level threshold and the dynamic offset are superimposed to obtain the threshold arithmetic sum, and the safety coefficient is combined to generate a real-time updated dynamic water level threshold. The embodiment makes the threshold have a dynamic prediction ability, for example, automatically increasing the threshold when processing water-absorbing instruments, and triggering pulse water replenishment in advance to offset the risk of rapid water loss. The dynamic water level threshold of the embodiment is based on the historical water consumption rate and the load type to adjust in real time, which significantly improves the water replenishment prediction accuracy of high water-absorbing load working conditions and avoids artificial experience errors.

[0093] Figure 3 An execution flowchart of a pulse water replenishment mechanism provided by the embodiment of the application is shown.

[0094] According to the embodiment of the application, as shown in Figure 3 , the pulse water replenishment mechanism is based on a preset pulse water replenishment mechanism, and the water replenishment rate is controlled according to the deviation of the water level information and the target water level information, specifically including:

[0095] S302, obtaining water level deviation information according to the deviation of the water level information and the target water level information;

[0096] S304, judging whether the water level deviation information is lower than a preset deviation threshold;

[0097] S306, if yes, configuring a short-period pulse mode, and adjusting the water replenishment PWM signal based on a preset feedback control algorithm;

[0098] S308, if no, configuring a long-period pulse mode, and adjusting the water replenishment PWM signal based on a preset linear mapping algorithm;

[0099] S310, after each pulse water replenishment period ends, collecting temperature information, and dynamically adjusting the working time of the next pulse period.

[0100] It should be noted that the embodiment provides a pulse water replenishment mechanism implementation process. First, the deviation value between the real-time water level and the target water level is calculated. If the deviation value is lower than the preset deviation threshold, it indicates that the target water level is approached, and then the short cycle pulse mode is switched, and the PID feedback control algorithm is used to dynamically adjust the PWM signal to gradually approach the target water level. If the deviation value is not lower than the preset deviation threshold, the long cycle pulse mode is configured, and the PWM signal of the water pump is adjusted through the preset linear mapping algorithm to gradually shorten the single water replenishment time and increase the stop time, and the water replenishment amount per unit time is adjusted in real time. In addition, the cavity temperature data is collected after each pulse cycle, and if the temperature fluctuation is detected to be out of limit, it indicates that the pulse water replenishment causes the temperature drop to be too large, and then the water replenishment time or the stop time of the next pulse cycle is dynamically adjusted to realize the temperature and water level double parameter collaborative control. The pulse mode used in the embodiment adjusts the PWM signal according to the water level deviation, and dynamically optimizes the pulse cycle in combination with the temperature feedback to effectively balance the water replenishment speed and the temperature stability.

[0101] According to the embodiment of the present application, the water replenishment rate is controlled based on the preset full water replenishment mechanism, specifically including:

[0102] The water replenishment PWM signal is set based on the preset full-speed water replenishment rate;

[0103] The real-time water level information is monitored to obtain the water level rising rate;

[0104] According to the deviation of the real-time water level information and the forced water level threshold, the rising rate threshold is obtained based on the preset rate threshold mapping relationship;

[0105] If the water level rising rate exceeds the rising rate threshold, the pulse water replenishment mechanism is switched to.

[0106] It should be noted that the embodiment provides an execution process of the full water replenishment mechanism. When the water level is lower than the forced water level threshold, the standard power output PWM signal is immediately output to drive the water pump to run at full speed; at the same time, the water level rising rate is monitored in real time. Then, according to the deviation of the real-time water level information and the forced water level threshold, the water level rising rate threshold is obtained according to the preset rate threshold mapping relationship; wherein the greater the deviation value, the higher the allowed rising rate. If it is detected that the actual water level rising rate exceeds the current allowed water level rising rate threshold, it indicates that the excessive water replenishment may cause the risk of overflow or temperature imbalance, and then the pulse water replenishment mode is automatically switched to reduce the water replenishment intensity through intermittent operation. In addition, the water level recovery progress is monitored synchronously during the water replenishment process to ensure that the full water replenishment is stopped when the water level is stably raised to the forced water level threshold. The water level rising rate is monitored in real time during the execution of the full water replenishment in the embodiment, and the pulse mode is automatically switched when the water level rising rate is out of limit, so as to prevent overflow and temperature drop, and ensure the safe operation of the equipment.

[0107] According to the embodiment of the present application, the cutting off the heating power supply based on the preset dry burning protection mechanism further comprises:

[0108] The sound and light alarm device is triggered and the device operation interface is locked at the same time of cutting off the heating power supply;

[0109] The cavity temperature information is monitored in real time;

[0110] If the temperature information exceeds the over-temperature threshold or the temperature rising rate exceeds the preset temperature rising safety threshold, the emergency cooling system is started;

[0111] Only when the preset reset operation instruction is received, the sterilization program is allowed to be restarted.

[0112] It should be noted that the embodiment provides an extension mechanism of dry burning protection. When the real-time water level is lower than the protection water level threshold, the main control system immediately cuts off the heating power supply and synchronously triggers the linkage protection mechanism. First, the sound and light alarm device is started, including but not limited to the buzzer ringing, the indicator light red light flashing, and the device operation interface is locked to prevent misoperation. Then, the cavity temperature change is monitored in real time. If the temperature value exceeds the safety upper limit or the temperature rising rate is abnormal, it indicates that the thermal inertia may cause local overheating, and then the emergency cooling system is automatically started, including but not limited to injecting cooling gas. Finally, the sterilization program is only allowed to be restarted when the operator performs the preset reset operation instruction, such as long-pressing the reset key or password verification, to ensure that the safety hidden trouble is completely eliminated. The embodiment forms a multiple fuse mechanism through the linkage sound and light alarm, emergency cooling and operation locking, and eliminates the risk of overheating damage of the device.

[0113] According to the embodiment of the present application, the updating the historical water consumption database based on the current water replenishment record specifically comprises:

[0114] The total water amount, the pulse number and the average single water replenishment amount of the current water replenishment are recorded;

[0115] The maximum temperature fluctuation value in the water replenishment process and the sterilization load weight are associated;

[0116] The coefficient of the linear mapping algorithm or the feedback control algorithm is adjusted according to the maximum temperature fluctuation value;

[0117] The load weight and water consumption mapping table is updated, which is used for subsequent calculation of dynamic water level threshold.

[0118] It should be noted that the embodiment provides a historical water consumption database updating mechanism. After the sterilization cycle ends, the key parameters of the entire water replenishment process are automatically recorded, including but not limited to total water replenishment amount, pulse trigger times, and average single water replenishment amount. At the same time, the maximum temperature fluctuation value during water replenishment and the actual weight data of the sterilization load are associated; wherein the maximum temperature fluctuation value reflects the influence degree of cold water injection on the thermal balance of the cavity. Then, based on the analysis result of the maximum temperature fluctuation value, the core coefficient in the pulse water replenishment control algorithm is dynamically adjusted. As an implementation manner, if the temperature fluctuation is out of limit, the proportional coefficient of the linear mapping algorithm is reduced or the integral weight of the feedback control algorithm is increased to weaken the impact of water replenishment on temperature. In addition, the mapping relationship between the load weight and the total water consumption is established and updated to the database; for example, high weight instrument load corresponds to higher water consumption benchmark value; the mapping table will be used as the initial input for calculating the dynamic water level threshold in the next cycle, realizing the adaptive water replenishment prediction of the load. Finally, a complete closed loop of data acquisition, algorithm optimization, and benchmark updating is formed, so that the system can continuously optimize the adaptability to different sterilization scenes. The embodiment dynamically adjusts the algorithm coefficient based on the temperature fluctuation data, and establishes the load water consumption mapping table, to continuously optimize the water replenishment efficiency of different sterilization scenes.

[0119] It is worth mentioning that after the water replenishment operation is completed, it also includes:

[0120] Real-time monitoring of water level information to obtain a water level curve;

[0121] According to the water level curve, a water level drop rate is obtained;

[0122] If the water level drop rate exceeds a preset water level drop rate threshold, secondary water replenishment is started, and water replenishment abnormality is marked;

[0123] When the number of consecutive occurrences of the water replenishment abnormality exceeds a preset number threshold, a self-checking program is triggered and the water level sensor is calibrated.

[0124] It should be noted that the embodiment provides a verification process after water replenishment. After completing the water replenishment operation, the real-time water level change is continuously monitored, the water level time curve is generated and the water level drop rate is calculated, which represents the amplitude of water level reduction per unit time. If it is detected that the water level drop rate exceeds the preset safety threshold, it indicates that there is potential leakage or abnormal evaporation, and the secondary water replenishment program is immediately started and marked as an abnormal event. At the same time, the temperature and pressure data at the time of the abnormal event are recorded for further analysis of the correlation between the water level drop rate and the temperature curve. If the water level abnormally drops when the temperature rises, it is determined that the evaporation is intensified, and the pulse water replenishment pause time needs to be extended; if the water level drops suddenly when the temperature is stable, it is suspected that the pipeline leaks, triggering the system self-check. When the number of consecutive abnormal marks reaches the preset upper limit, the system self-check program is forcibly started. As an embodiment, the water level sensor zero drift, water pump tightness and valve closing state are checked in turn to ensure that the equipment is in a safe and controllable state. The embodiment verifies the water level drop rate after water replenishment, triggers secondary water replenishment and sensor calibration when abnormal, solves the problem of hidden leakage, and ensures the reliability of water level control.

[0125] It is worth mentioning that it also includes:

[0126] Real-time monitoring of water level information and temperature information to obtain water level curve and temperature curve;

[0127] The water level curve and the temperature curve are input into a pre-trained water replenishment cycle adjustment model to obtain the cycle length of the pulse water replenishment mechanism.

[0128] It should be noted that the embodiment provides an adaptive water replenishment cycle adjustment mechanism. Real-time data is synchronously collected by a water level sensor and a temperature sensor to generate a water level change curve and a temperature change curve, respectively, representing water replenishment demand and thermal stability. The two curves are input into a pre-trained machine learning model, which learns from historical data sets to derive correlation rules between water level fluctuation frequency, temperature drop slope and optimal pulse cycle. For example, when the water level curve shows a rapid downward trend and the temperature curve maintains a high level, the model outputs instructions to shorten the pulse cycle length to speed up water replenishment; conversely, when the temperature curve drops steeply, the pulse pause time is extended. The model continuously receives the latest running data for iterative optimization, and finally dynamically outputs the pulse start-stop time length combination adapted to the current working condition, achieving the dual goals of accurate water level regulation and temperature stability. The embodiment inputs the water level and temperature curves into the pre-trained model to output the optimal pulse cycle, realizes intelligent water replenishment decision-making with double-parameter cooperation, and reduces the need for manual parameter adjustment.

[0129] It is worth mentioning that it also includes dynamically adjusting target water level information, specifically:

[0130] Selecting a basic target water level according to the sterilization load type;

[0131] According to the temperature information, a compensation target water level is obtained based on a preset temperature water level compensation relationship;

[0132] According to the basic target water level and the compensation target water level, target water level information is synthesized.

[0133] In the pulse water replenishment process, target water level information updating is performed every preset number of water replenishment cycles.

[0134] It should be noted that the embodiment provides a target water level dynamic adjustment mechanism. First, the basic target water level is selected according to the sterilization load type. As an implementation, when processing surgical instruments, a higher water level reference is used to compensate for the water absorption of porous materials; when processing liquid bottles, a lower water level reference is used to avoid boiling overflow. Second, a dynamic compensation value is calculated based on real-time temperature values, and the thermal expansion effect of water caused by high temperature is offset through a preset temperature water level compensation relationship table. The logic of the relationship table is that for every specific interval of temperature increase, the target water level increases by a corresponding compensation amount. For example, the target water level is appropriately increased under high temperature conditions to ensure an effective sterilization environment. In the pulse water replenishment process, target water level synthesis calculation and updating are performed after completing 5 water replenishment cycles. The compensation value is updated in combination with the latest temperature data, and is superimposed with the basic target water level to generate a new instruction value, so that the target water level always adapts to the real-time working condition, avoiding the control failure problem of a fixed target value in a variable temperature environment. In the embodiment, the target water level is dynamically compensated according to the load type and temperature, avoiding control deviation caused by high temperature expansion or evaporation, and improving the adaptability to complex working conditions.

[0135] Figure 4 A block diagram of a sterilization pot adaptive water replenishment control system based on water level monitoring is shown.

[0136] As shown in Figure 4 The second aspect of the present application discloses a sterilization pot adaptive water replenishment control system 4 based on water level monitoring, comprising a memory 41 and a processor 42, the memory comprising a sterilization pot adaptive water replenishment control method program based on water level monitoring, the sterilization pot adaptive water replenishment control method program based on water level monitoring is executed by the processor to realize the following steps:

[0137] Read the historical water consumption database, and obtain a dynamic water level threshold based on a preset threshold model;

[0138] Obtain water level information;

[0139] Determine whether the water level information is lower than a preset protection water level threshold;

[0140] If yes, cut off the heating power supply based on a preset dry burning protection mechanism;

[0141] If not, determine whether the water level information is lower than a preset forced water level threshold;

[0142] If yes, the water replenishment rate is controlled based on a preset full-amount water replenishment mechanism until the water level information rises to the dynamic water level threshold;

[0143] If no, it is determined whether the water level information is lower than the dynamic water level threshold;

[0144] If yes, the water replenishment rate is controlled according to the deviation of the water level information from the target water level information based on a preset pulse water replenishment mechanism;

[0145] After the sterilization cycle ends, the historical water consumption database is updated based on the water replenishment record of this time.

[0146] It should be noted that the water level information is the water level in the heating tank of the sterilization pot; the historical water consumption database includes water replenishment records in multiple sterilization weeks; and the water replenishment record at least includes water consumption and pulse parameters.

[0147] The embodiment provides a sterilization pot adaptive water replenishment control process based on water level monitoring. After the sterilization pot system is started, the historical water consumption database is first read, which stores the water replenishment records of past sterilization cycles, including water consumption, pulse parameters and the like. A dynamic water level threshold is generated based on a preset threshold model; wherein the dynamic water level threshold is real-time floating with the historical water consumption mode and is always higher than the forced water level threshold and the protection water level threshold. Then the real-time water level information in the heating tank of the sterilization pot is continuously obtained through the water level sensor, and a three-level linked judgment mechanism is executed. First, it is compared whether the water level is lower than the protection water level threshold. If it is lower than the protection water level threshold, the heating power is immediately cut off and the dry burning protection mechanism is activated to prevent the equipment from being damaged by empty burning; if it is not lower than the protection water level threshold, it is further determined whether the water level is lower than the forced water level threshold. If it is lower than the forced water level threshold, the full-amount water replenishment mechanism is started to replenish water at a constant standard rate until the water level rises to the forced water level threshold. If the water level is between the dynamic water level threshold and the forced water level threshold, the pulse water replenishment mechanism is enabled, and the pulse period is dynamically adjusted according to the deviation value of the real-time water level and the target water level, and intermittent water replenishment is adopted to avoid temperature drop. As an embodiment, high-frequency long pulse is adopted when the water level deviation is large, and low-frequency short pulse is adopted when the water level deviation is small. Finally, at the end of the sterilization cycle, the total water consumption, pulse frequency and other data of this time of water replenishment are automatically summarized and updated to the historical water consumption database to form a closed loop optimization. Through the three-level threshold linkage response and closed loop data update, the embodiment realizes adaptive water replenishment under unattended condition, completely eliminates the dry burning risk and improves the sterilization continuity.

[0148] Figure 2 A flowchart for generating a dynamic water level threshold provided by the embodiment of the application is shown.

[0149] According to the embodiment of the application, as Figure 2As shown, the reading history water database obtains a dynamic water level threshold based on a preset threshold model, and specifically includes:

[0150] Extracting the average water consumption rate of at least two recent sterilization cycles in the history water consumption database;

[0151] According to the average water consumption rate, combined with the length of the current sterilization stage, a dynamic offset is calculated;

[0152] According to the sterilization load type, a safety coefficient is obtained based on a preset coefficient mapping table;

[0153] Superimposing the forced water level threshold and the dynamic offset, combined with the safety coefficient, a real-time updated dynamic water level threshold is generated.

[0154] It should be noted that the embodiment provides a generation process of a dynamic water level threshold. First, the average water consumption rate data of at least two recent sterilization cycles is extracted from the history water consumption database, which reflects the water consumption law of the device under typical load. Combined with the running time of the current sterilization stage, a dynamic offset is calculated, wherein the calculation logic is that the longer the running time, the higher the risk of water level drop. Then, according to the load type in the sterilization pot, such as porous instruments, liquid bottles, etc., a preset coefficient mapping table is queried to determine the adaptive safety coefficient. Finally, the forced water level threshold and the dynamic offset are superimposed to obtain the threshold arithmetic sum, and combined with the safety coefficient, a real-time updated dynamic water level threshold is generated. The embodiment makes the threshold have dynamic prediction ability, such as automatically increasing the threshold when processing water-absorbing instruments, and triggering pulse water replenishment in advance to offset the risk of rapid water loss. The dynamic water level threshold of the embodiment is adjusted in real time based on the historical water consumption rate and the load type, which significantly improves the water replenishment prediction accuracy of high water-absorbing load working conditions and avoids artificial experience errors.

[0155] Figure 3 An execution flowchart of a pulse water replenishment mechanism provided by the embodiment of the application is shown.

[0156] According to the embodiment of the application, as Figure 3 shown, the pulse water replenishment mechanism is based on a preset pulse water replenishment mechanism, and the water replenishment rate is controlled according to the deviation of the water level information and the target water level information, and specifically includes:

[0157] According to the deviation of the water level information and the target water level information, water level deviation information is obtained;

[0158] Determine whether the water level deviation information is lower than a preset deviation threshold;

[0159] If yes, configure a short-period pulse mode, and adjust the water replenishment PWM signal based on a preset feedback control algorithm;

[0160] If not, the long-period pulse mode is configured, and the water replenishment PWM signal is adjusted based on a preset linear mapping algorithm;

[0161] After each pulse water replenishment period ends, temperature information is collected, and the working duration of the next pulse period is dynamically adjusted.

[0162] It should be noted that the embodiment provides a pulse water replenishment mechanism implementation process. Firstly, the deviation value between the real-time water level and the target water level is calculated. If the deviation value is lower than the preset deviation threshold, it indicates that the target water level is approached, and the short-period pulse mode is switched to, and the PID feedback control algorithm is used to dynamically adjust the PWM signal to gradually approach the target water level. If the deviation value is not lower than the preset deviation threshold, the long-period pulse mode is configured, and the PWM signal of the water pump is adjusted by the preset linear mapping algorithm to gradually shorten the single water replenishment duration and increase the stop duration, and the water replenishment amount in unit time is adjusted in real time. In addition, after each pulse period ends, the cavity temperature data is collected. If it is detected that the temperature fluctuation is out of limit, it indicates that the pulse water replenishment causes the temperature drop to be too large, and the water replenishment duration or the stop time of the next pulse period is dynamically adjusted to realize the temperature and water level double-parameter collaborative control. The pulse mode used in the embodiment adjusts the PWM signal according to the water level deviation, and dynamically optimizes the pulse period in combination with the temperature feedback, so that the water replenishment speed and the temperature stability are effectively balanced.

[0163] According to the embodiment of the present application, the water replenishment rate is controlled based on a preset full-amount water replenishment mechanism, and specifically includes:

[0164] The water replenishment PWM signal is set based on the preset full-speed water replenishment rate;

[0165] The real-time water level information is monitored, and the water level rising rate is calculated;

[0166] According to the deviation of the real-time water level information and the forced water level threshold, the rising rate threshold is obtained based on a preset rate threshold mapping relationship;

[0167] If the water level rising rate exceeds the rising rate threshold, the pulse water replenishment mechanism is switched to.

[0168] It should be noted that the embodiment provides an execution flow of a full water replenishment mechanism. When the water level is lower than the forced water level threshold, a standard power output PWM signal is immediately output to drive the water pump to run at full speed; at the same time, the water level rising rate is monitored in real time. Then, according to the deviation of the real-time water level information and the forced water level threshold, the water level rising rate threshold is obtained according to the preset rate threshold mapping relationship; the greater the deviation value, the higher the allowed rising rate. If it is detected that the actual water level rising rate exceeds the current allowed water level rising rate threshold, it indicates that excessive water replenishment may exist the risk of overflow or temperature imbalance, and then the pulse water replenishment mode is automatically switched to, and the water replenishment intensity is reduced through intermittent operation. In addition, the water level recovery progress is monitored synchronously during the water replenishment process, so that the full water replenishment is stopped when the water level is stably raised to the forced water level threshold. The embodiment monitors the water level rising rate in real time when the full water replenishment is executed, and automatically switches to the pulse mode when the water level rising rate is out of limit, so as to prevent overflow and temperature drop, and ensure safe operation of the equipment.

[0169] According to the embodiment of the present application, the heating power is cut off based on the preset dry burning protection mechanism, and further comprises:

[0170] When the heating power is cut off, the audible and visual alarm device is triggered and the device operation interface is locked;

[0171] The cavity temperature information is monitored in real time;

[0172] If the temperature information exceeds the over-temperature threshold or the temperature rising rate exceeds the preset temperature rise safety threshold, the emergency cooling system is started;

[0173] Only when the preset reset operation instruction is received, the sterilization program is allowed to be restarted.

[0174] It should be noted that the embodiment provides an extension mechanism of dry burning protection. When the real-time water level is lower than the protection water level threshold, the main control system immediately cuts off the heating power and synchronously triggers the linkage protection mechanism. First, the audible and visual alarm device is started, including but not limited to the buzzing of a buzzer and the flashing of a red light, and the device operation interface is locked to prevent misoperation. Then, the cavity temperature change is monitored in real time, and if the temperature value exceeds the safety upper limit or the temperature rising rate is abnormal, it indicates that thermal inertia may cause local overheating, and then the emergency cooling system is automatically started, including but not limited to the injection of cooling gas. Finally, the sterilization program is only allowed to be restarted when the operator performs the preset reset operation instruction, such as long-pressing the reset key or password verification, to ensure that the safety hidden danger is completely eliminated. The embodiment forms a multiple fuse mechanism through linkage audible and visual alarm, emergency cooling and operation locking, to eliminate the risk of equipment overheating damage.

[0175] According to the embodiment of the present application, the historical water consumption database is updated based on the current water replenishment record, and specifically comprises:

[0176] record the total water volume, the number of pulses and the average single water volume of the current water replenishment;

[0177] correlate the maximum temperature fluctuation value during the water replenishment process and the sterilization load weight;

[0178] adjust the coefficients of the linear mapping algorithm or the feedback control algorithm according to the maximum temperature fluctuation value;

[0179] update the load weight and water consumption mapping table for subsequent calculation of the dynamic water level threshold.

[0180] It should be noted that the embodiment provides a historical water consumption database updating mechanism. After the sterilization cycle ends, the key parameters of the current water replenishment process are automatically recorded, including but not limited to the total water replenishment volume, the number of pulse triggers and the average single water replenishment volume. At the same time, the maximum temperature fluctuation value during the water replenishment process and the actual weight data of the sterilization load are correlated; wherein the maximum temperature fluctuation value reflects the influence degree of cold water injection on the thermal balance of the cavity. Then, based on the maximum temperature fluctuation value analysis result, the core coefficients in the pulse water replenishment control algorithm are dynamically adjusted. As an implementation manner, if the temperature fluctuation is out of limit, the proportional coefficient of the linear mapping algorithm is reduced or the integral weight of the feedback control algorithm is increased to weaken the impact of water replenishment on temperature. In addition, the load weight and the total water consumption are mapped and updated to the database; for example, high weight instrument load corresponds to higher water consumption benchmark value; the mapping table will be used as the initial input for calculating the dynamic water level threshold in the next cycle, realizing the load adaptive water replenishment prediction. Finally, a complete closed loop of data collection, algorithm optimization and benchmark updating is formed, so that the system can continuously optimize the adaptability to different sterilization scenes. The embodiment dynamically adjusts the algorithm coefficients based on the temperature fluctuation data and establishes the load water consumption mapping table, continuously optimizing the water replenishment efficiency of different sterilization scenes.

[0181] It is worth mentioning that after the water replenishment operation is completed, it also includes:

[0182] real-time monitoring of water level information to obtain a water level curve;

[0183] obtaining a water level drop rate according to the water level curve;

[0184] if the water level drop rate exceeds a preset water level drop rate threshold, starting secondary water replenishment and marking water replenishment abnormality;

[0185] when the number of consecutive occurrences of the water replenishment abnormality exceeds a preset number threshold, triggering a self-checking program and calibrating the water level sensor.

[0186] It should be noted that the embodiment provides a verification process after water replenishment. After completing the water replenishment operation, the real-time water level change is continuously monitored, the water level time curve is generated and the water level drop rate is calculated, which represents the amplitude of water level reduction per unit time. If it is detected that the water level drop rate exceeds the preset safety threshold, it indicates that there is potential leakage or abnormal evaporation, and the secondary water replenishment program is immediately started and marked as an abnormal event. At the same time, the temperature and pressure data at the time of the abnormal event are recorded for further analysis of the correlation between the water level drop rate and the temperature curve. If the water level abnormally drops when the temperature rises, it is determined that the evaporation is intensified, and the pulse water replenishment pause time needs to be extended; if the water level drops suddenly when the temperature is stable, it is suspected that the pipeline leaks, triggering the system self-check. When the number of consecutive abnormal marks reaches the preset upper limit, the system self-check program is forcibly started. As an embodiment, the water level sensor zero drift, water pump tightness and valve closing state are checked in turn to ensure that the equipment is in a safe and controllable state. The embodiment verifies the water level drop rate after water replenishment, triggers secondary water replenishment and sensor calibration when abnormal, solves the problem of hidden leakage, and ensures the reliability of water level control.

[0187] It is worth mentioning that it also includes:

[0188] Real-time monitoring of water level information and temperature information to obtain a water level curve and a temperature curve;

[0189] The water level curve and the temperature curve are input into a pre-trained water replenishment cycle adjustment model to obtain a cycle length of the pulse water replenishment mechanism.

[0190] It should be noted that the embodiment provides an adaptive water replenishment cycle adjustment mechanism. Real-time data is synchronously collected by a water level sensor and a temperature sensor to generate a water level change curve and a temperature change curve, respectively, representing water replenishment demand and thermal stability. The two curves are input into a pre-trained machine learning model, which learns from historical data sets to derive correlation rules between water level fluctuation frequency, temperature drop slope and optimal pulse cycle. For example, when the water level curve shows a rapid downward trend and the temperature curve maintains a high level, the model outputs instructions to shorten the pulse cycle length to speed up water replenishment; conversely, when the temperature curve drops steeply, the pulse pause time is extended. The model continuously receives the latest running data for iterative optimization, and finally dynamically outputs a pulse start-stop time length combination that adapts to the current working condition, achieving the dual goals of accurate water level regulation and temperature stability. The embodiment inputs the water level and temperature curves into the pre-trained model to output the optimal pulse cycle, realizes intelligent water replenishment decision-making with double-parameter cooperation, and reduces the need for manual parameter adjustment.

[0191] It is worth mentioning that it also includes dynamically adjusting target water level information, specifically:

[0192] Selecting a basic target water level according to the sterilization load type;

[0193] According to the temperature information, a compensation target water level is obtained based on a preset temperature water level compensation relationship;

[0194] According to the basic target water level and the compensation target water level, target water level information is synthesized.

[0195] During the pulse water supplement process, target water level information updating is performed every preset number of water supplement cycles.

[0196] It should be noted that the embodiment provides a target water level dynamic adjustment mechanism. First, the basic target water level is selected according to the sterilization load type. As an implementation manner, when processing surgical instruments, a higher water level reference is used to compensate for the water absorption of porous materials; when processing liquid bottles, a lower water level reference is used to avoid boiling overflow. Secondly, a dynamic compensation value is calculated based on real-time temperature values, and the thermal expansion effect of water caused by high temperature is offset through a preset temperature water level compensation relationship table. The logic of the relationship table is that for every specific interval of temperature increase, the target water level increases by a corresponding compensation amount. For example, the target water level is appropriately increased under high temperature conditions to ensure an effective sterilization environment. During the pulse water supplement process, target water level synthesis calculation and updating are performed after every 5 water supplement cycles are completed. The compensation value is updated in combination with the latest temperature data, and is superimposed with the basic target water level to generate a new instruction value, so that the target water level always adapts to the real-time working condition, avoiding the control failure problem of a fixed target value in a variable temperature environment. In the embodiment, the target water level is dynamically compensated according to the load type and temperature, avoiding control deviation caused by high temperature expansion or evaporation, and improving the adaptability to complex working conditions.

[0197] The third aspect of the present application provides a computer readable storage medium, wherein a water level monitoring based sterilization pot adaptive water supplement control method program is included in the computer readable storage medium, and when the water level monitoring based sterilization pot adaptive water supplement control method program is executed by a processor, the steps of the water level monitoring based sterilization pot adaptive water supplement control method according to any one of the above are implemented.

[0198] In summary, the application provides a sterilization pot adaptive water replenishment control method and system based on water level monitoring and a medium, generates a dynamic water level threshold by reading a historical water consumption database, and acquires heating tank water level information in real time; when the water level is lower than the protection water level threshold, the heating power is cut off and dry burning protection is triggered; when the water level is lower than the forced water level threshold, full water replenishment is started until the forced water level threshold is reached; when the water level is between the forced water level threshold and the dynamic water level threshold, pulse water replenishment is started based on the deviation of the real-time water level and the target water level to dynamically adjust the water replenishment rate; finally, the water consumption database is updated after the sterilization cycle ends, forming a closed loop optimization; the application predicts the water replenishment opportunity through a dynamic threshold, balances the water replenishment efficiency and temperature stability based on a hierarchical response mechanism, and continuously optimizes the control parameters using historical data, significantly reduces the dry burning risk and the need for manual intervention, and realizes the safe and autonomous operation of the sterilization equipment under variable load and long cycle conditions.
