BRIEF DESCRIPTION OF DRAWINGS
[0037] Figure 1 A structural schematic diagram of a device unit operation control system of the present application is given.
[0038] Figure 2 A logic diagram for obtaining a hardness hidden danger index of the present application is given. DETAILED DESCRIPTION
[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0040] EMBODIMENT
[0041] Figure 1 A structural schematic diagram of a device unit operation control system of the present application is given. The device unit operation control system comprises a softened state evaluation module, a pipeline hidden danger monitoring module, a condition control judgment module, a humidification operation judgment module and a humidification early warning control module.
[0042] The softened state evaluation module collects softened water hardness information, judges the operation hidden danger degree of the softened water device through the softened water hardness information, and controls the operation of the softened water device based on the judgment result of the operation hidden danger degree of the softened water device.
[0043] The pipeline hidden danger monitoring module monitors the abnormal situation of the pressure of the humidification water pipeline, and evaluates the stability of the humidification water pipeline according to the abnormal situation of the pressure of the humidification water pipeline.
[0044] The condition control judgment module judges whether the operation condition of the humidifier is met based on the comprehensive analysis of the judgment result of the operation hidden danger degree of the softened water device and the stability of the humidification water pipeline.
[0045] The humidification operation judgment module collects the resistance value data of the resistance heating pipe of the humidifier, obtains the resistance value change rate according to the resistance value data, and evaluates the health state of the resistance heating pipe of the humidifier based on the resistance value change rate.
[0046] When the operation condition of the humidifier is met, the humidification early warning control module comprehensively analyzes the operation hidden danger degree of the softened water device, the stability of the humidification water pipeline and the health state of the resistance heating pipe of the humidifier, and performs real-time early warning on the operation state of the humidifier.
[0047] By monitoring the softened water hardness information, it can be found whether there is an abnormality in the operation of the softened water device. If the hardness value exceeds the normal range, it may mean that the softened water device has a fault, poor treatment effect or improper operation, etc. Regularly collecting softened water hardness information and analyzing its change trend can evaluate the performance stability of the softened water device. If the hardness value fluctuates greatly or the change trend is unstable, it may indicate that the softened water device has certain operation problems or performance degradation. By continuously monitoring the hardness information of the softened water, it can help the management personnel to find the operation problems of the softened water device in time and take corresponding maintenance and management measures to ensure the normal operation of the softened water device.
[0048] The softened water hardness information includes a hardness hidden danger index, wherein, Figure 2 The acquisition logic diagram of the hardness hidden danger index is given, and the acquisition logic of the hardness hidden danger index is as follows:
[0049] S1: Real-time monitoring and acquisition of the conductivity data of the softened water treated by the softened water device by conductivity measurement method, specifically: installing a conductivity measuring instrument at the water outlet or water pipe of the softened water device, ensuring that the measuring instrument is in full contact with the softened water and can accurately measure the conductivity of the softened water, and using the conductivity measuring instrument to monitor the conductivity data of the softened water produced by the softened water device in real time. Record and store the conductivity data obtained each time.
[0050] S2: Based on the conductivity data of the softened water, the conductivity data of the softened water is converted into the hardness value of the softened water, specifically:
[0051] Generally, there is a certain negative correlation between the conductivity of the softened water and the hardness value, that is, the lower the hardness value of the softened water, the higher the conductivity; the higher the hardness value, the lower the conductivity. This is because the hardness of the softened water mainly comes from salts such as calcium carbonate and magnesium carbonate, and when these salts are dissociated into ions in water, it will cause the conductivity to increase.
[0052] A relationship model between the conductivity of the softened water and the hardness value of the softened water is established, for example, a possible relationship model between the conductivity of the softened water and the hardness value of the softened water is: wherein, is the hardness value of the softened water (expressed in ppm or mg / L); is the conductivity of the softened water (expressed in μS / cm); is the slope of the linear relationship model, is less than 0, represents the proportional relationship between conductivity and hardness value; is the intercept of the linear relationship model, representing the basic value of the hardness value when the conductivity is zero.
[0053] The higher the conductivity of the softened water, the lower the hardness value of the softened water; the lower the conductivity of the softened water, the higher the hardness value of the softened water.
[0054] The greater the hardness value of the softened water, the higher the hardness of the water treated by the water softening device. High-hardness water contains more calcium carbonate, magnesium carbonate and other substances, which will deposit in the water softening device and form scale, increasing the cleaning and maintenance frequency of the water softening device. Carbonates in high-hardness water can adhere to the softening resin or other softening media, affecting the softening efficiency of the softener and reducing the working efficiency of the water softening device. Long-term use of high-hardness water can damage the softening resin or other softening media, shorten the service life of the water softening device, and increase the repair and replacement costs. Calcium carbonate, magnesium carbonate and other substances in high-hardness water are prone to scale inside the humidifier, clogging the humidifier nozzle or waterway, and affecting the normal operation of the humidifier. Scale can reduce the working efficiency of the humidifier, reduce the amount of water mist produced by the humidifier, and thus reduce the humidification effect, affecting the humidity control of the data center.
[0055] S3: Set the hardness monitoring interval, and calculate the hardness hazard index by analyzing the abnormality degree of the hardness value of the softened water in the hardness monitoring interval.
[0056] The hardness monitoring interval is a real-time monitoring interval, i.e., the endpoint of the hardness monitoring interval is always a real-time time point, and the time length corresponding to the hardness monitoring interval is set according to the actual monitoring demand of the hardness of the softened water and other actual conditions, and the time length corresponding to the hardness monitoring interval is fixed.
[0057] The hardness value of the softened water in the hardness monitoring interval is obtained, it is judged whether the hardness value of the softened water is greater than the safety hardness threshold, the abnormality degree of the hardness value of the softened water in the hardness monitoring interval is analyzed, i.e., the degree of the hardness value of the softened water greater than the safety hardness threshold in the hardness monitoring interval is analyzed, and the hardness hazard index is calculated, and the expression is: , wherein, is the hardness hazard index, respectively, the number of the hardness value of the softened water greater than the safety hardness threshold in the hardness monitoring interval and the number of the hardness value of the softened water greater than the safety hardness threshold in the hardness monitoring interval; , and are positive integers, respectively, the i-th hardness value of the softened water greater than the safety hardness threshold in the hardness monitoring interval and the safety hardness threshold; is the time length corresponding to the hardness monitoring interval.
[0058] The greater the hardness risk index, the greater the degree to which the hardness value of the softened water within the hardness monitoring interval exceeds the safety hardness threshold, and the greater the degree of operational risk of the softened water device. High-hardness salts in the softened water can scale inside the humidifier, clog the humidifier's nozzles or waterways, and affect the normal operation of the humidifier.
[0059] The safety hardness threshold refers to the maximum allowable value that the hardness of the softened water cannot exceed. Exceeding this value can lead to equipment failure, scaling, clogging, and other problems, thereby affecting the normal operation of the system. This threshold is usually determined by relevant industry standards, manufacturer recommendations, or practical experience to ensure the safe operation and long-term reliability of the equipment. The safety hardness threshold is usually determined according to the design and requirements of the humidifier. In general, water with excessively high hardness can cause scaling and clogging inside the humidifier, affecting humidification effectiveness and even damaging the humidifier. Therefore, the safety hardness threshold needs to be reasonably set according to the characteristics of the humidifier and the operating environment to ensure the normal operation of the humidifier and the safety of the equipment.
[0060] The hardness risk threshold is set by professionals in the field based on the size of the hardness risk index and other actual conditions such as safety requirements for softened water used in the humidification equipment unit in the data center. This will not be repeated here.
[0061] The hardness risk index is compared with the hardness risk threshold to determine the degree of operational risk of the softened water device:
[0062] When the hardness risk index is greater than the hardness risk threshold, a softened water device operation risk signal is generated, indicating that the degree of operational risk of the softened water device is high, which can cause hardness salts in high-hardness water to easily scale and clog inside the humidifier, leading to blockage of the humidifier's nozzles or waterways, and even causing the humidifier to malfunction or be damaged. Humidifier failure or reduced humidification effectiveness can affect the operation of the data center. If the humidifier cannot work normally, it may cause the humidity in the data center environment to be unstable, and even affect the normal operation of the equipment.
[0063] When the hardness risk index is less than or equal to the hardness risk threshold, a softened water device operation normal signal is generated, indicating that the degree of operational risk of the softened water device is within an acceptable range (low risk) or nonexistent.
[0064] Based on the judgment result of the operation risk degree of the softening water device, the operation of the softening water device is controlled, that is, when the softening water device operation risk signal is generated, the operation of the softening water device can be immediately stopped to prevent water with hardness value exceeding the safety limit value from entering the humidifier or other equipment, thereby reducing the operation risk. After stopping the operation of the softening water device, the parameters of the softening water device can be adjusted, such as increasing the input amount of softening agent or increasing the working time of the softening water device, to reduce the content of hardness salts in water, thereby reducing the operation risk.
[0065] When the softening water device operation normal signal is generated, the operation of the softening water device is maintained.
[0066] The pipeline risk monitoring module evaluates the stability of the humidification water pipeline, specifically:
[0067] The pipeline pressure range is set based on the set safety pressure range of the humidification water pipeline corresponding to the operation mode of the humidification equipment unit. The pipeline pressure range is set to be less than the set safety pressure range of the humidification water pipeline, for example, assuming that the set safety pressure range of the humidification water pipeline is 10 to 15 psi (pound per square inch), we can set the pipeline pressure range to be smaller than the set safety pressure range, for example, set to 8 to 12 psi. This can leave a certain safety margin within the set safety pressure range to cope with unexpected situations or system fluctuations.
[0068] Real-time acquisition of the pressure value of the humidification water pipeline: install a pressure sensor or pressure transmitter on the humidification water pipeline. Usually, the sensor is installed at a suitable position on the pipeline to ensure accurate measurement of the pressure in the pipeline.
[0069] Monitoring of abnormal conditions of the pressure of the humidification water pipeline: obtaining the time length of the pressure value of the humidification water pipeline not in the pipeline pressure range within the time T closest to the real-time time, marking the ratio of the time length of the pressure value of the humidification water pipeline not in the pipeline pressure range within the time T to the time length of the time T as the pipeline stability abnormality ratio. The larger the pipeline stability abnormality ratio, the worse the stability of the humidification water pipeline, indicating that the frequency of abnormal conditions of the pipeline pressure is higher, and the pressure stability of the pipeline is worse. This may cause unstable operation of the system and increase the risk of equipment failure.
[0070] Wherein, the time length of time T is set according to actual conditions, which will not be repeated here.
[0071] Setting the pipeline stability abnormality ratio threshold, the pipeline stability abnormality ratio threshold is set by the professional technicians in the field according to the safety requirement standards of the pressure value of the humidification water pipeline and other actual conditions, which will not be repeated here.
[0072] When the pipeline stability abnormality ratio is greater than the pipeline stability abnormality ratio threshold, a pipeline unstable signal is generated, indicating that the humidification water pipeline is unstable, and further measures need to be taken for adjustment and maintenance. Check the connection parts of the humidification water pipeline to ensure that there is no looseness or water leakage at the connection. For problematic connection parts, reinstallation or replacement of sealing elements is required to ensure the sealing of the pipeline. According to the specific circumstances of the pipeline pressure abnormality, the working parameters of the humidifier, such as the operation mode of the humidifier and the flow of humidification water, may need to be adjusted to adapt to the actual situation of the pipeline.
[0073] When the pipeline stability abnormality ratio is less than or equal to the pipeline stability abnormality ratio threshold, a pipeline stable signal is generated, indicating that the humidification water pipeline is stable, and there is a low risk of pipeline stability, but it is within an acceptable range, and no special treatment is required temporarily, but further analysis is still needed in the future.
[0074] The condition control judgment module determines whether the humidifier operating conditions are met, specifically:
[0075] The resistance heating tube of the humidifier is one of the key components of the heater and one of the parts prone to failure. These resistance heating tubes are usually used to heat softened water to produce water vapor to increase the humidity in the air. Due to the high temperature and humidity of the working environment, the resistance heating tube of the humidifier is easily affected by factors such as scale, corrosion and thermal fatigue, resulting in performance degradation or even failure. In the humidifier, the resistance heating tube is usually in a high-temperature and humid environment, and long-term work may cause the accumulation of scale or corrosion in the tube, affecting the heating efficiency and stability of the heating tube. In addition, due to the frequent heating and cooling of the resistance heating tube during the operation of the humidifier, long-term use may cause thermal fatigue of the tube material, thereby reducing its durability.
[0076] The quality of the water treated by the softening water device has a significant impact on the resistance heating tube of the humidifier. If the softening water device malfunctions or does not soften the water effectively, it may result in water supplied to the humidifier not meeting the requirements, containing too many minerals or impurities, thereby affecting the normal operation of the resistance heating tube of the humidifier, increasing the risk of clogging or damage to the resistance heating tube. The operating status of the softening water device also affects the water volume and stability of the humidifier's water supply. If the softening water device fails or the water volume is unstable, it may result in insufficient or fluctuating water supply to the humidifier, affecting the working effect of the resistance heating tube of the humidifier. The operating status of the softening water device also affects the water pressure of the humidifier. If the softening water device has unstable or abnormal pressure, it may cause the water supply pressure of the humidifier to fluctuate, affecting the working effect of the resistance heating tube of the humidifier, and even causing the water level of the humidifier to be unstable or overflow. Therefore, the real-time operating status of the softening water device has a certain impact on the operating status of the resistance heating tube of the humidifier. In order to ensure the normal operation of the resistance heating tube of the humidifier, it is necessary to ensure the normal operation of the softening water device, the stability of the softened water quality, and the stability of the water volume and water pressure of the water supply. Timely inspection and maintenance of the softening water device can effectively reduce the adverse effects on the resistance heating tube of the humidifier.
[0077] The pressure stability of the humidification water pipeline will affect the operating status of the resistance heating tube of the humidifier. The following is the possible impact of pressure stability on the operating status of the resistance heating tube: If the pressure of the humidification water pipeline is insufficient, it may result in insufficient water supply to the humidifier. In the humidifier, the resistance heating tube needs sufficient water flow to heat the water and generate steam. If the water supply pressure is insufficient, the water flow may not meet the requirements of the resistance heating tube, affecting the working effect of the heating tube. If the pressure of the humidification water pipeline fluctuates or is unstable, it may cause the water supply volume and water pressure of the humidifier to fluctuate. In this case, the resistance heating tube may be affected by different degrees of water pressure, resulting in unstable or uneven heating effect, and even causing the water level of the humidifier to be unstable or overflow. If the pressure of the humidification water pipeline is too large, it may cause unnecessary pressure and load on the resistance heating tube of the humidifier. Long-term excessive water pressure may cause the resistance heating tube to overheat or be damaged, affecting the safe and stable operation of the humidifier. Therefore, the pressure stability of the humidification water pipeline is very important for the operating status of the resistance heating tube of the humidifier. Ensuring the pressure stability and appropriateness of the humidification water pipeline can ensure the normal water supply volume and water pressure of the humidifier, thereby ensuring the normal operation of the resistance heating tube and improving the working efficiency and stability of the humidifier.
[0078] Determine whether the humidifier operating conditions are met, specifically: when the softening water device is running normally and the pipeline is stable, it is determined that the humidifier operating conditions are met, at which time the humidifier can be kept running; otherwise, it is determined that the humidifier operating conditions are not met, and the humidifier is stopped when the humidifier operating conditions are not met, and professional technicians are arranged to overhaul the humidification equipment unit.
[0079] By determining whether the humidifier operating conditions are met, the operation of the humidifier can be effectively controlled, ensuring that the humidifier is kept running only when the softening water device is normal and the humidification water pipeline is stable, thereby ensuring the normal operation and safety of the humidification system.
[0080] The humidification operation judgment module evaluates the health status of the humidifier resistance heating tube, specifically:
[0081] Select a suitable sensor to measure the resistance value of the humidifier resistance heating tube. A sensor or measurement module specifically designed for measuring resistance can be used.
[0082] Connect the selected sensor to the humidifier resistance heating tube, ensuring proper and secure connection.
[0083] Use an embedded system such as a microcontroller or single-chip microcomputer to write a program to periodically collect resistance value data of the humidifier resistance heating tube. The specific steps include:
[0084] Set the timer: set the timer to trigger data collection operations every certain period of time.
[0085] Read the resistance value: in the timer interrupt, read the resistance value of the humidifier resistance heating tube through the sensor.
[0086] Store the data: store the resistance value data read into memory or external storage for subsequent analysis and processing.
[0087] Periodically collect resistance value data of the humidifier resistance heating tube, for example, collect resistance value data of the humidifier resistance heating tube every 1 minute, and calculate the resistance value change rate based on the resistance value data of the humidifier resistance heating tube, which is expressed as: where, are the resistance value change rate, the resistance value of the resistance heating tube measured at the current time, and the resistance value of the resistance heating tube measured at the previous time at the current time, respectively.
[0088] If the resistance value change rate of the resistance heating tube is large, exceeding the set threshold, it indicates that the resistance value of the resistance heating tube has changed significantly, which may indicate abnormal conditions such as aging, damage or failure, etc.
[0089] Occasionally, the resistance value of the resistance heating tube changes significantly, which may have little impact on the health of the resistance heating tube. This may be due to temporary fluctuations caused by external environmental factors or operational errors. In this case, if the change is not persistent, the health of the resistance heating tube is usually not severely affected.
[0090] However, if the resistance value of the resistance heating tube changes significantly frequently over a period of time, it needs to be paid attention to. Frequent resistance value changes may indicate that the resistance heating tube has persistent problems such as aging, damage or failure. In this case, the resistance heating tube needs to be checked and maintained in time to ensure the normal operation of the humidifier. Frequent abnormal situations may affect the stability and reliability of the humidifier, and even cause equipment damage or downtime.
[0091] Set a resistance value monitoring interval, wherein the resistance value monitoring interval is a real-time monitoring interval, i.e. the end point of the resistance value monitoring interval is always a real-time time point, and the time length corresponding to the resistance value monitoring interval is set according to the actual monitoring requirement of the resistance value change rate of the resistance heating tube and other actual situations, and the time length corresponding to the resistance value monitoring interval is fixed.
[0092] Set a resistance value change rate threshold, when the resistance value change rate of the resistance heating tube is greater than the resistance value change rate threshold, it indicates that the resistance heating tube has abnormal situation, may be failure or aging.
[0093] By analyzing the frequency of the resistance value change rate greater than the resistance value change rate threshold in the resistance value monitoring interval, the resistance value change abnormality index is calculated, which is the ratio of the number of times of the resistance value change rate greater than the resistance value change rate threshold in the resistance value monitoring interval to the time length corresponding to the resistance value monitoring interval, i.e. the greater the resistance value change abnormality index, the worse the health status of the resistance heating tube of the humidifier, which is not conducive to the normal operation of the humidifier and even the entire humidification equipment unit, resulting in the safety of the data center equipment cannot be guaranteed.
[0094] Wherein, the resistance value change rate threshold is set by the professional technical personnel in the art according to the safety requirement standard of the resistance value change rate of the resistance heating tube and other actual situations, which will not be repeated here.
[0095] If the softening water device has a fault or unstable operation, it may cause impurities or excessive minerals in the humidification water, which may in turn cause an increase in scale or dirt on the surface of the humidifier resistance heating tube. These scales or dirt will affect the heat dissipation effect and working efficiency of the resistance heating tube, which may cause the performance of the resistance heating tube to decline, and even cause the failure of the humidifier. If there is a water leakage, blockage or other problems in the humidification water pipeline, it may cause the humidifier to fail to supply water normally or the water pressure to be unstable. These problems will affect the working state of the resistance heating tube of the humidifier, such as causing the resistance heating tube to overheat or insufficient heating, thereby affecting the humidification effect and stability of the humidifier.
[0096] Since the degree of operation risk of the softening water device and the stability of the humidification water pipeline will affect the resistance heating tube of the humidifier, thereby affecting the operation state of the humidifier, when the operation condition of the humidifier is met, the health state of the resistance heating tube of the humidifier is combined with the degree of operation risk of the softening water device and the stability of the humidification water pipeline to perform real-time early warning on the operation state of the humidifier. Specifically:
[0097] When it is determined that the operation condition of the humidifier is met, the hardness risk index, the pipeline stability abnormality ratio and the resistance value change abnormality index are normalized, and the normalized hardness risk index, pipeline stability abnormality ratio and resistance value change abnormality index are respectively assigned to a preset proportion coefficient to calculate a humidification operation risk warning coefficient. For example, the humidification operation risk warning coefficient can be calculated by the following formula, and its expression is: wherein, are the humidification operation risk warning coefficient, the hardness risk index, the pipeline stability abnormality ratio and the resistance value change abnormality index, respectively, are preset proportion coefficients of the hardness risk index, the pipeline stability abnormality ratio and the resistance value change abnormality index, respectively, wherein, are all greater than 0, is set according to the actual situation, which will not be described here.
[0098] According to the calculation formula of the humidification operation risk warning coefficient, it can be known that the humidification operation risk warning coefficient reflects the comprehensive influence of the degree of operation risk of the softening water device, the pipeline stability abnormality ratio and the resistance value change abnormality index on the operation of the humidifier. The greater the humidification operation risk warning coefficient, the worse the operation state of the humidifier, which means that the humidifier faces a high operation risk and may have various problems such as hardness risk, pipeline stability problem and abnormality of the resistance heating tube.
[0099] The humidification operation risk warning threshold is set by the professional technicians in the field according to the humidification operation risk warning coefficient and other actual conditions such as the safety requirement standard for the operation of the humidifier and the humidification equipment unit, which will not be described here.
[0100] According to the comparison of the humidification operation risk warning coefficient and the humidification operation risk warning threshold, the running state of the humidifier is warned in real time:
[0101] When the humidification operation risk warning coefficient is greater than the humidification operation risk warning threshold, it is determined to generate a running warning signal, indicating that the running state of the humidifier has a high risk, which may have serious hardness hidden danger, pipe stability problem or resistance heating pipe abnormality, etc. At this time, according to the running warning signal, the operator or the system automatic control system is prompted to strengthen the monitoring and maintenance of the humidifier and the humidification equipment unit, and the following control measures are taken:
[0102] Stop the humidifier running: immediately stop the operation of the humidifier to prevent possible failure or damage from further deterioration, and avoid damage to the data center equipment.
[0103] Overhaul and maintenance: overhaul and maintenance of the humidifier, softening water device and humidification water pipeline to eliminate hardness hidden danger, pipe stability problem and resistance heating pipe abnormality, etc.
[0104] Adjust the water quality control: adjust the operating parameters of the softening water device to optimize the water quality of the humidification water and reduce the influence of scale and dirt on the resistance heating pipe.
[0105] Update equipment or parts: replace damaged or severely aged parts as needed to ensure normal operation of the humidifier.
[0106] When the humidification operation risk warning coefficient is less than or equal to the humidification operation risk warning threshold, it is determined to generate a running normal signal, indicating that the running state of the humidifier is within the normal range, and no additional measures are needed.
[0107] The above formulas are dimensionless to calculate their numerical values. The formula is obtained by software simulation of a large amount of data to obtain the most recent real situation. The preset parameters and threshold values in the formula are set by the technicians in the field according to the actual situation.
