The humidity control problem has not received enough attention for quite a long time. Many data centers do not have hygrometers, and the air conditioning system does not support dry and humidity adjustment. This has buried hidden dangers for the operation of data centers. Controlling the humidity of the data center within a reasonable range can effectively extend the working life of the equipment. The humidification equipment unit is a type of equipment unit that aims to control the humidity of the data center within a reasonable range. The humidification equipment unit includes a humidifier, a humidification water pipeline, and a softening water device. The humidifier uses a resistance heating tube to heat softened water to generate water vapor.

The humidity of the data center can be controlled and adjusted through the humidification equipment unit.

[0004] However, in the actual operation of the humidification equipment unit, if the operating status of the humidification equipment unit cannot be monitored, it will be impossible to accurately understand the working condition of the humidification equipment unit and the humidification effect, etc., which may lead to the inability to correctly control the humidification equipment unit, which may affect the humidity control effect of the data center and the operating stability of the equipment.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of an equipment unit operation control system of the present invention; Figure 2 This is a logical diagram for obtaining the hardness hidden danger index of the present invention. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example Figure 1A structural schematic diagram of an equipment unit operation control system of the present invention is given, which includes a softening 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.

[0019] The softening state assessment module collects softened water hardness information, judges the degree of operational hazards of the softening water device through the softened water hardness information, and controls the operation of the softening water device based on the judgment result of the degree of operational hazards of the softening water device.

[0020] The pipeline hidden danger monitoring module monitors the abnormal pressure of the humidification water pipeline, and evaluates the stability of the humidification water pipeline based on the abnormal pressure of the humidification water pipeline.

[0021] The condition control judgment module judges whether the operating conditions of the humidifier are met based on a comprehensive analysis of the judgment results of the operating hidden danger degree of the softening water device and the stability of the humidification water pipeline.

[0022] The humidification operation judgment module collects the resistance data of the resistance heating tube of the humidifier, obtains the resistance change rate according to the resistance data, and evaluates the health status of the resistance heating tube of the humidifier based on the resistance change rate.

[0023] When the operating conditions of the humidifier are met, the humidification early warning control module will conduct a comprehensive analysis of the operating risk level of the softening water device, the stability of the humidification water pipeline and the health status of the resistance heating tube of the humidifier, and provide real-time early warning of the operating status of the humidifier.

[0024] By monitoring the hardness information of softened water, it is possible to promptly detect any abnormalities during the operation of the softened water device. If the hardness value exceeds the normal range, it may mean that the softened water device has problems such as failure, poor treatment effect or improper operation. Regularly collecting softened water hardness information and analyzing its changing trends can evaluate the performance stability of the softened water device. If the hardness value fluctuates greatly or the changing trend is unstable, it may indicate that the softened water device has certain operating problems or performance degradation. By continuously monitoring the hardness information of softened water, it can help managers to promptly detect operating problems of the softened water device and take corresponding maintenance and management measures to ensure the normal operation of the softened water device.

[0025] Softened water hardness information includes hardness risk index, among which: Figure 2 A schematic diagram of the logic for obtaining the hardness hidden danger index is given. The specific logic for obtaining the hardness hidden danger index is as follows: S1: The conductivity data of the softened water treated by the softening water device is obtained by real-time monitoring through the conductivity measurement method, specifically: the conductivity measuring instrument is installed in the water outlet or water pipe of the softening 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 the conductivity measuring instrument is used to monitor the conductivity data of the softened water produced by the softening water device in real time. The conductivity data obtained from each measurement is recorded and stored.

[0026] S2: Based on the conductivity data of softened water, the conductivity data of softened water is converted into the hardness value of softened water, specifically: Generally speaking, there is a certain negative correlation between the conductivity and hardness value of softened water, that is, the lower the hardness value of softened water, the higher the conductivity; the higher the hardness value, the lower the conductivity. This is because the hardness of softened water mainly comes from salts such as calcium carbonate and magnesium carbonate, and these salts will cause an increase in conductivity when they dissociate into ions in water.

[0027] A relationship model between the conductivity of softened water and the hardness value of softened water is established. For example, a possible relationship model between the conductivity of softened water and the hardness value of softened water is: ,in, is the hardness value of softened water (expressed in ppm or mg / L); is the conductivity of softened water (expressed in μS / cm); is the slope of the linear relationship model, Less than 0, Represents the proportional relationship between conductivity and hardness value; is the intercept of the linear relationship model, representing the base value of hardness when the conductivity is zero.

[0028] That is, the higher the conductivity of softened water, the lower the hardness value of softened water; the lower the conductivity of softened water, the higher the hardness value of softened water.

[0029] The greater the hardness value of softened water, the higher the hardness of the water after being treated by the softening water device. High-hardness water contains more substances such as calcium carbonate and magnesium carbonate, which will be deposited in the softening water device to form scale, increasing the cleaning and maintenance frequency of the softening water device. The carbonate in high-hardness water will adhere to the softening resin or other softening medium, affecting the softening efficiency of the softener, resulting in reduced working efficiency of the softening water device. Long-term use of high-hardness water may damage the softening resin or other softening medium, shorten the service life of the softening water device, and increase maintenance and replacement costs. Calcium carbonate and magnesium carbonate in high-hardness water are easy to scale inside the humidifier, blocking the humidifier nozzle or waterway, affecting the normal operation of the humidifier. Scaling will reduce the working efficiency of the humidifier and reduce the amount of water mist produced by the humidifier, thereby reducing the humidification effect and affecting the humidity control of the data center.

[0030] S3: Set the hardness monitoring interval, and calculate the hardness hidden danger index by analyzing the abnormal degree of the hardness value of the softened water within the hardness monitoring interval.

[0031] Among them, the hardness monitoring interval is a real-time monitoring interval, that is, the end point of the hardness monitoring interval is always a real-time time point. The time length corresponding to the hardness monitoring interval is set according to the actual monitoring needs of softened water hardness and other actual conditions, and the time length corresponding to the hardness monitoring interval is fixed.

[0032] Obtain the hardness value of softened water within the hardness monitoring interval, determine whether the hardness value of softened water is greater than the safety hardness threshold, analyze the abnormal degree of the hardness value of softened water within the hardness monitoring interval, that is, analyze the degree to which the hardness value of softened water within the hardness monitoring interval is greater than the safety hardness threshold, and calculate the hardness hidden danger index, which is expressed as: ,in, is the hardness hidden danger index, They are respectively the number of hardness values ​​of softened water greater than the safety hardness threshold within the hardness monitoring interval and the serial number of the hardness value of softened water greater than the safety hardness threshold; ,and are all positive integers, are the hardness value of the i-th softened water greater than the safety hardness threshold in the hardness monitoring interval and the safety hardness threshold, respectively; is the time length corresponding to the hardness monitoring interval.

[0033] The greater the hardness hidden danger index, the greater the degree to which the hardness value of softened water in the hardness monitoring range exceeds the safety hardness threshold, and the greater the operating hidden danger of the softening water device. The high hardness salts in the softened water will scale inside the humidifier, clogging the nozzle or water channel of the humidifier, affecting the normal operation of the humidifier.

[0034] Among them, the safety hardness threshold refers to the maximum allowable value that the hardness value of softened water cannot exceed. Exceeding this value may cause equipment failure, scaling, clogging and other problems, thus affecting the normal operation of the system. This threshold is usually determined by relevant industry standards, manufacturer's 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. Generally speaking, water with too high a hardness value may cause scaling and clogging inside the humidifier, thereby affecting the humidification effect 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.

[0035] A hardness hidden danger threshold is set. The hardness hidden danger threshold is set by professional and technical personnel in this field based on the size of the hardness hidden danger index and other actual conditions such as the safety requirements for softened water used in humidification equipment units in data centers. It will not be repeated here.

[0036] Compare the hardness hidden danger index with the hardness hidden danger threshold to judge the degree of hidden danger in the operation of the softening water device: When the hardness hidden danger index is greater than the hardness hidden danger threshold, it is determined that the softening water device operation risk signal is generated. At this time, the softening water device operation risk level is relatively high, which will cause the hardness salts in the high-hardness water to easily scale and clog the humidifier, resulting in blockage of the humidifier nozzle or waterway, and even causing humidifier failure or damage. Humidifier failure or reduced humidification effect may affect the operation of the data center. If the humidifier fails to work properly, it may cause the humidity of the data center environment to be unstable, and even affect the normal operation of the equipment.

[0037] When the hardness hidden danger index is less than or equal to the hardness hidden danger threshold, it is determined that a normal operation signal of the softening water device is generated. At this time, the operation hidden danger level of the softening water device is within an acceptable range (there is a low risk) or there is no hidden danger.

[0038] Based on the judgment result of the degree of hidden dangers in the operation of the water softening device, the operation of the water softening device is controlled, that is, when the risk signal of the operation of the water softening device is generated, the operation of the water softening device can be stopped immediately to prevent water with a hardness value exceeding the safety limit from entering the humidifier or other equipment, thereby reducing the operation risk. After stopping the operation of the water softening device, the parameters of the water softening device can be adjusted, such as increasing the input amount of softener or increasing the working time of the water softening device, to reduce the content of hardness salts in the water, thereby reducing the operation risk.

[0039] When a normal operation signal of the softening water device is generated, the operation of the softening water device is maintained.

[0040] The pipeline hidden danger monitoring module evaluates the stability of the humidification water pipeline, specifically: Set the pipeline pressure range. The pipeline pressure range is set based on the set safety pressure range of the humidification water pipeline corresponding to the operating mode of the humidification equipment unit. Set the pipeline pressure range to be smaller 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 (pounds per square inch), we can set the pipeline pressure range to be smaller than the set safety pressure range, such as 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.

[0041] Get the pressure value of the humidification water pipeline in real time: 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 that the pressure in the pipeline can be accurately measured.

[0042] Monitor the abnormal situation of the pressure of the humidification water pipeline: obtain the time length of the humidification water pipeline pressure value that is not within the pipeline pressure range within the time T closest to the real time, and mark the ratio of the time length of the humidification water pipeline pressure value that is not within 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 situation of pipeline pressure is high and the pressure stability of the pipeline is worse. This may cause unstable operation of the system and increase the risk of equipment failure.

[0043] The length of time T is set according to actual conditions and will not be described in detail here.

[0044] The pipeline stability abnormality ratio threshold is set. The pipeline stability abnormality ratio threshold is set by professional and technical personnel in this field according to the safety requirements for the pressure value of the humidification water pipeline and other actual conditions, and will not be repeated here.

[0045] When the pipeline stability abnormality ratio is greater than the pipeline stability abnormality ratio threshold, it is determined that a pipeline unstable signal is generated. At this time, the stability of the humidification water pipeline is poor, and further measures need to be taken for adjustment and maintenance; check the connection parts of the humidification water pipeline to ensure that there are no loose connections or leaks. For problematic connection parts, it is necessary to reinstall or replace the seals to ensure the sealing of the pipeline. Depending on the specific situation of the pipeline pressure abnormality, it may be necessary to adjust the working parameters of the humidifier, such as the operation mode of the humidifier, the flow rate of the humidification water, etc., to adapt to the actual situation of the pipeline.

[0046] When the pipeline stability abnormality ratio is less than or equal to the pipeline stability abnormality ratio threshold, it is determined that a pipeline stability signal is generated. At this time, the stability of the humidification water pipeline is normal, indicating that the stability of the pipeline may have a low risk, but it is within an acceptable range and no special treatment is required for the time being. Further analysis is required in the future.

[0047] The condition control judgment module judges whether the operating conditions of the humidifier are met, specifically: The resistance heating tube of the humidifier is one of the key components of the heater and one of the parts that is prone to failure. These resistance heating tubes are usually used to heat softened water to generate 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 susceptible to factors such as scaling, corrosion and thermal fatigue, which can lead to performance degradation or even failure. In a humidifier, the resistance heating tube is usually in a high temperature and humid environment. Long-term operation may cause the accumulation of scale or corrosion in the tube, affecting the heating efficiency and stability of the heating tube. In addition, since the resistance heating tube needs to be frequently heated and cooled during the operation of the humidifier, long-term use may cause thermal fatigue of the tube, thereby reducing its durability.

[0048] The water quality treated by the softening water device has a great influence on the resistance heating tube of the humidifier. If the softening water device works abnormally or the softening effect is not good, the water quality supplied to the humidifier may not meet the requirements and contain too many minerals or impurities, thereby affecting the normal operation of the resistance heating tube of the humidifier and increasing the risk of blockage or damage of the resistance heating tube. The operating state of the softening water device will also affect the water volume and stability of the humidifier water supply. If the softening water device fails or the water volume is unstable, it may cause insufficient or fluctuating water supply to the humidifier, affecting the working effect of the resistance heating tube of the humidifier. The operating state of the softening water device will also affect the water pressure of the humidifier. If the pressure of the softening water device is unstable or abnormal, 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 state of the softening water device has a certain influence on the operating state 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 softening 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 to ensure its normal operation can effectively reduce the adverse effects on the humidifier resistance heating tube.

[0049] The pressure stability of the humidification water pipeline will affect the operating state of the humidifier resistance heating tube. The following are the possible effects of pressure stability on the operating state of the resistance heating tube: If the pressure of the humidification water pipeline is insufficient, it may cause insufficient water supply to the humidifier. In the humidifier, the resistance heating tube requires sufficient water flow to heat the water and generate steam. If the water supply pressure is insufficient, the water flow may not be enough to 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 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 may even cause the water level of the humidifier to be unstable or overflow. If the pressure of the humidification water pipeline is too high, it may cause unnecessary pressure and load on the resistance heating tube of the humidifier. Excessive water pressure for a long time may cause overheating or damage to the resistance heating tube, affecting the safe and stable operation of the humidifier. Therefore, the pressure stability of the humidification water pipeline is very important for the operating state of the humidifier resistance heating tube. Ensuring that the pressure of the humidification water pipeline is stable and appropriate can ensure the normal water supply 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.

[0050] Determine whether the operating conditions of the humidifier are met, specifically: when the softening water device is operating normally and the pipeline is stable, it is determined that the operating conditions of the humidifier are met, and the humidifier can be kept running; otherwise, it is determined that the operating conditions of the humidifier are not met. When the operating conditions of the humidifier are not met, stop the operation of the humidifier and arrange professional technicians to inspect and repair the humidification equipment unit.

[0051] By judging whether the operating conditions of the humidifier 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.

[0052] The humidification operation judgment module evaluates the health status of the resistance heating tube of the humidifier, specifically: Select a suitable sensor to measure the resistance of the humidifier resistance heating tube. You can use a sensor or measurement module specially designed for measuring resistance.

[0053] Connect the selected sensor to the humidifier resistance heater tube, making sure the connection is correct and secure.

[0054] Use an embedded system such as a microcontroller or single-chip microcomputer to write a program to periodically collect the resistance data of the humidifier resistance heating tube. The specific steps include: Set timer: Set a timer to trigger data collection at a certain interval.

[0055] Read resistance: In the timer interrupt, read the resistance of the humidifier resistance heating tube through the sensor.

[0056] Store data: Store the read resistance data in memory or external storage for subsequent analysis and processing.

[0057] The resistance data of the humidifier resistance heating tube is collected regularly, for example, the resistance data of the humidifier resistance heating tube is collected every 1 minute, and the resistance change rate is calculated based on the resistance data of the humidifier resistance heating tube. The expression is: ,in, They are respectively the resistance change rate, the resistance value of the resistance heating tube measured at the current moment, and the resistance value of the resistance heating tube measured last time at the current moment.

[0058] If the resistance change rate of the resistance heating tube is large and exceeds the set threshold, it means that the resistance of the resistance heating tube has changed significantly, and there may be an abnormal situation, such as aging, damage or failure.

[0059] Occasional large changes in the resistance of the resistance heater may have little impact on the health of the resistance heater. It may be a temporary fluctuation caused by external environmental factors or operating errors. In this case, if the change is not continuous, the health of the resistance heater is usually not seriously affected.

[0060] However, if the resistance value of the resistance heating tube changes frequently over a period of time, it is necessary to pay attention. Frequent resistance changes may indicate that there are persistent problems with the resistance heating tube, such as aging, damage, or failure. In this case, the resistance heating tube needs to be inspected and maintained in time to ensure the normal operation of the humidifier. Frequent abnormal conditions may affect the stability and reliability of the humidifier, and may even cause equipment damage or shutdown.

[0061] A resistance monitoring interval is set, wherein the resistance monitoring interval is a real-time monitoring interval, that is, the end point of the resistance monitoring interval is always a real-time time point, and the time length corresponding to the resistance monitoring interval is set according to the actual monitoring requirements for the resistance change rate of the resistance heating tube and other actual conditions, and the time length corresponding to the resistance monitoring interval is fixed.

[0062] Set the resistance change rate threshold. When the resistance change rate of the resistance heating tube is greater than the resistance change rate threshold, it indicates that the resistance heating tube is abnormal and may be faulty or aged.

[0063] By analyzing the frequency of the resistance change rate being greater than the resistance change rate threshold in the resistance monitoring interval, the resistance change abnormality index is calculated. The resistance change abnormality index is the ratio of the number of times the resistance change rate is greater than the resistance change rate threshold in the resistance monitoring interval to the time length corresponding to the resistance monitoring interval. That is, the larger the resistance change abnormality index is, the worse the health status of the resistance heating tube of the humidifier is, 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 not being guaranteed.

[0064] Among them, the resistance change rate threshold is set by professional and technical personnel in this field based on other actual conditions such as the safety requirement standard for the resistance change rate of the resistance heating tube, and will not be repeated here.

[0065] If the softening water device is faulty or unstable, the humidified water may contain impurities or excessive minerals, which may cause scale or dirt to increase on the surface of the humidifier's 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 may even cause the humidifier to malfunction. If there are leaks, blockages or other problems in the humidification water pipeline, the humidifier may not be able to supply water normally or the water pressure may be unstable. These problems will affect the working state of the humidifier's resistance heating tube, for example, it may cause the resistance heating tube to overheat or underheat, thereby affecting the humidification effect and stability of the humidifier.

[0066] Since the operating risk level of the softening water device and the stability of the humidification water pipeline will affect the resistance heating tube of the humidifier, thus affecting the operating status of the humidifier, when the operating conditions of the humidifier are met, the health status of the resistance heating tube of the humidifier is combined with the operating risk level of the softening water device and the stability of the humidification water pipeline to provide real-time warning of the operating status of the humidifier. Specifically: When it is determined that the operating conditions of the humidifier are met, the hardness hidden danger index, the pipeline stability abnormality ratio and the resistance change abnormality index are normalized, and the humidification operation risk warning coefficient is calculated by assigning the normalized hardness hidden danger index, the pipeline stability abnormality ratio and the resistance change abnormality index to preset proportional coefficients respectively. For example, the present invention can calculate the humidification operation risk warning coefficient by the following formula, and its expression is: ,in, They are humidification operation risk warning coefficient, hardness hidden danger index, pipeline stability abnormality ratio and resistance change abnormality index. They are the preset proportional coefficients of hardness hidden danger index, pipeline stability abnormality ratio and resistance change abnormality index, among which, are greater than 0, It is set according to the actual situation and will not be described here.

[0067] According to the calculation formula of the humidification operation risk warning coefficient, the humidification operation risk warning coefficient reflects the comprehensive impact of factors such as the degree of operational hidden dangers of the softening water device, the pipeline stability abnormality ratio, and the resistance change abnormality index on the operation of the humidifier. The larger the humidification operation risk warning coefficient, the worse the operating state of the humidifier, indicating that the humidifier faces a higher operational risk and may have multiple problems such as hardness hidden dangers, pipeline stability problems, and abnormal resistance heating tubes.

[0068] The humidification operation risk warning threshold is set by professional and technical personnel in this field based on the humidification operation risk warning coefficient and other actual conditions such as the safety requirements for the operation of the humidifier and the humidification equipment unit, and will not be repeated here.

[0069] According to the comparison between the humidification operation risk warning coefficient and the humidification operation risk warning threshold, the operation status of the humidifier is warned in real time: When the humidification operation risk warning coefficient is greater than the humidification operation risk warning threshold, an operation warning signal is generated, indicating that the operation status of the humidifier is at a high risk, and there may be serious hardness hazards, pipeline stability problems, or abnormal resistance heating tubes. At this time, according to the operation warning signal, the operator or the system automatic control system is prompted to strengthen the monitoring and maintenance of the humidifier and humidification equipment unit, and take the following control measures: Stop humidifier operation: Immediately stop the operation of the humidifier to prevent possible failure or damage from further deterioration and avoid damage to data center equipment.

[0070] Inspection and maintenance: Comprehensive inspection and maintenance of humidifiers, softening water devices and humidification water pipelines to eliminate root causes such as hardness hazards, pipeline stability problems and resistance heating tube abnormalities.

[0071] Adjust water quality control: adjust the operating parameters of the softening water device, optimize the water quality of the humidification water, and reduce the impact of scale and dirt on the resistance heating tube.

[0072] Update equipment or parts: Replace damaged or aged parts as needed to ensure the normal operation of the humidifier.

[0073] When the humidification operation risk warning coefficient is less than or equal to the humidification operation risk warning threshold, it is determined that a normal operation signal is generated, indicating that the operating status of the humidifier is within the normal range and no additional measures are required.

[0074] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation.
