Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and in particular to a method, system, device and medium for obtaining correction parameters of a water heater and a fan thereof. Background Art

[0002] During the combustion process, a gas water heater requires real-time calculation of the difference between the fan's actual speed and theoretical speed. Feedback control is then performed based on this difference to ensure that the water heater's constant temperature output remains constant despite environmental changes. The theoretical speed is determined through extensive experiments under standard operating conditions. By adjusting the load during the water heater's operation, sampling the actual fan speed and target flow rate in real time, and fitting the data. Currently, sampling fan calibration parameters, such as the water heater's actual fan speed and target flow rate, is typically done manually. However, this sampling method is time-consuming and produces inaccurate data. Summary of the Invention

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a method for obtaining fan correction parameters, which is applied to a water heater and includes:

[0009] Determining a corresponding correction parameter acquisition method based on a preset speed range to which the actual speed belongs;

[0010] A plurality of groups of data on the actual rotation speed and the working current of the water heater in the correction parameter acquisition mode are obtained and used as fan correction parameters.

[0011] The method for obtaining fan correction parameters provided in this solution controls the working load of the water heater so that the actual fan speed changes evenly in sequence, and automatically collects a series of actual speeds and the working current of the water heater under different loads as fan correction parameters.

[0024] If the actual speed is lower than the minimum speed of the preset speed range, determining a second correction parameter acquisition method, wherein the second correction parameter acquisition method corresponds to increasing the workload of the water heater until the actual speed is less than or equal to the maximum speed;

[0025] If the actual speed is within the preset speed range, a third correction parameter acquisition method is determined, and the third correction parameter acquisition method corresponds to not changing the workload of the water heater.

[0026] In this solution, by controlling the actual speed of the fan to be within the preset speed range, the actual speed increases or decreases in sequence according to a certain speed increment, so that more evenly distributed sampling data can be obtained, the accuracy of subsequent data fitting can be improved, and the accuracy of the fan correction parameters can be improved.

[0027] Preferably, the step of reducing the workload includes:

[0029] The step of increasing the workload comprises:

[0030] Increase the operating temperature of the water heater, and / or increase the water flow rate of the water heater.

[0031] In this solution, the workload of the water heater is adjusted by adjusting the set temperature and water flow of the water heater, which can improve the flexibility and accuracy of the workload adjustment of the water heater.

[0032] The present invention also provides a system for acquiring fan correction parameters, which is applied to a water heater and includes:

[0033] An adjustment instruction receiving module, used for receiving a load adjustment instruction;

[0037] The correction parameter acquisition module is used to obtain a plurality of groups of data on the actual rotation speed and the working current of the water heater in the correction parameter acquisition mode and use them as fan correction parameters.

[0038] The fan correction parameter acquisition system provided by this solution controls the working load of the water heater so that the actual fan speed changes evenly in sequence, and automatically collects a series of actual speeds and the working current of the water heater under different loads as fan correction parameters. On the one hand, it can improve the efficiency of data collection, and on the other hand, it can obtain more accurate fan correction parameters and fit the relationship between the working current and the actual speed under more accurate standard working conditions, so that the fan status can be accurately and timely adjusted during the subsequent operation of the water heater, ensuring the water output control of the water heater and improving the user's water use experience.

[0039] Preferably, when the current load of the water heater is greater than the minimum operating load, the load adjustment module is further configured to:

[0040] increasing the current load of the water heater to the preset load according to a first preset load increment;

[0041] or,

[0043] In this solution, the flexibility of the method for obtaining the fan correction parameters can be improved by adjusting the water heater workload in different ways.

[0047] The minimum parameter acquisition module is used to obtain the actual speed and the operating current under the minimum operating load as the fan correction parameters.

[0069] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0070] Example 1

[0071] This embodiment provides a method for obtaining fan calibration parameters, which is applied to water heaters, such as Figure 1 As shown, the acquisition method includes the following steps:

[0072] S1, receiving load adjustment instructions;

[0073] S2. adjusting the working load of the water heater to a preset load based on the load adjustment instruction;

[0074] S3, obtaining the actual speed of the fan of the water heater under the preset load;

[0075] S4. Determine a corresponding correction parameter acquisition method based on the preset speed range to which the actual speed belongs;

[0076] S5. Acquire several sets of data on actual rotation speeds and operating currents of the water heater in a correction parameter acquisition mode and use them as fan correction parameters.

[0077] To obtain the fan correction parameters of the water heater, it is necessary to obtain the linear scatter data of the water heater's operating current and the corresponding actual fan speed under different loads under standard operating conditions, and fit the relationship between the operating current and the actual speed under standard operating conditions to obtain the theoretical speed of the fan.

[0078] Specifically, step S1 receives a load adjustment instruction, including an instruction to increase or decrease the load. Step S2 adjusts the water heater's workload to a preset load based on the load increase or decrease instruction. The water heater's workload can be adjusted by changing the water heater's set temperature, water flow rate, and other methods. Step S obtains the actual fan speed at the preset load. It should be noted that the actual speed here refers to the actual speed corresponding to different workloads under standard operating conditions and is not equal to the actual operating speed of the water heater.

[0079] The preset speed range in step S4 is determined based on the actual speed of the last adjustment, with the purpose of ensuring that the data of the actual speed sampling is evenly distributed, and the speed increment is optimal at around 100 rpm. For example, the actual speeds of multiple samplings are controlled to be 3000 rpm, 3100 rpm, 3200 rpm, etc. If the speed increment is too large after adjusting the workload, and the actual speed increases directly from 3000 rpm to 3190 rpm, it is necessary to reduce the workload and the actual speed. Therefore, the corresponding correction parameter acquisition method includes increasing or decreasing the workload of the water heater so that the actual speed is within the preset speed range, and then obtaining the correction parameter, as well as directly obtaining the correction parameter without changing the workload.

[0080] Step S5 obtains several sets of actual rotational speeds and operating currents as fan calibration parameters.

[0081] The method for obtaining fan correction parameters provided in this embodiment controls the working load of the water heater so that the actual fan speed changes evenly in sequence, and automatically collects a series of actual speeds and the working current of the water heater under different loads as fan correction parameters. On the one hand, it can improve the efficiency of data collection, and on the other hand, it can obtain more accurate fan correction parameters and fit the relationship between the working current and the actual speed under more accurate standard working conditions, so that the state of the fan can be accurately and timely adjusted during the subsequent operation of the water heater, thereby ensuring the water output control of the water heater and improving the user's water use experience.

[0082] Example 2

[0083] Based on Example 1, this example provides a method for obtaining correction parameters of a fan.

[0084] In one feasible solution, when the current load of the water heater is greater than the minimum operating load, step S2 includes:

[0085] increasing the current load of the water heater to a preset load according to a first preset load increment;

[0086] or,

[0087] According to the second preset load increment, the current load of the water heater is reduced to the preset load.

[0088] Specifically, when the current load of the water heater is greater than the minimum operating load of the water heater, sampling can be performed while the load is sequentially increased, or sampling can be performed while the load is sequentially decreased.

[0089] In this solution, the flexibility of the method for obtaining the fan correction parameters can be improved by adjusting the water heater workload in different ways.

[0090] In one feasible solution, when the current load of the water heater is the lowest operating load, step S2:

[0091] According to a third preset load increment, the current load of the water heater is increased to the preset load.

[0092] Specifically, if the current load of the water heater is the lowest operating load, sampling can only be performed by increasing the load in sequence.

[0093] In one feasible solution, when the current load of the water heater is the minimum operating load, the obtaining method further includes:

[0094] The actual speed and operating current under the lowest operating load are obtained as the fan calibration parameters.

[0095] In this solution, by obtaining the actual speed and operating current starting from the lowest operating load, the range of fan correction parameter acquisition can be increased, as much data that can be used for fan correction as possible can be obtained, and the accuracy of fan correction parameter acquisition can be improved, thereby ensuring the accuracy and effectiveness of the fan status during subsequent water heater operation.

[0096] In one feasible solution, step S4 includes:

[0097] If the actual speed exceeds the maximum speed of the preset speed range, determining a first correction parameter acquisition method, the first correction parameter acquisition method corresponding to reducing the workload of the water heater until the actual speed is less than or equal to the maximum speed;

[0098] If the actual speed is lower than the minimum speed of the preset speed range, a second correction parameter acquisition method is determined, and the second correction parameter acquisition method corresponds to increasing the workload of the water heater until the actual speed is less than or equal to the maximum speed;

[0099] If the actual speed is within the preset speed range, the third correction parameter acquisition method is determined, and the third correction parameter acquisition method corresponds to not changing the workload of the water heater.

[0100] Specifically, after adjusting the workload of the water heater in step S2, the actual speed and operating current cannot be immediately obtained as fan calibration parameters. It is also necessary to determine whether the actual speed meets the sampling requirements, that is, whether it meets the speed increment of about 100 rpm.

[0101] For example, if the actual speed of the previous sampling was 3000 rpm, and the speed increment between 90 rpm and 110 rpm meets the requirements, the preset speed range for this time is 3090 rpm to 3110 rpm. If the actual speed is greater than 3110 rpm, the water heater workload is reduced; if the actual speed is less than 3090 rpm, the water heater workload is increased; if the actual speed is between 3090 rpm and 3110 rpm, the water heater workload does not need to be changed.

[0102] In this solution, by controlling the actual speed of the fan to be within the preset speed range, the actual speed increases or decreases in sequence according to a certain speed increment, so that more evenly distributed sampling data can be obtained, the accuracy of subsequent data fitting can be improved, and the accuracy of the fan correction parameters can be improved.

[0103] In one feasible solution, the steps of reducing workload include:

[0104] Reduce the operating temperature of the water heater and / or reduce the water flow rate of the water heater.

[0105] Specifically, the workload of the water heater can be reduced by reducing the set temperature, reducing the water flow rate, or a combination of the two.

[0106] Of course, in actual operation, setting one of the temperature and water flow rate to increase and the other to decrease can also be used as a way to reduce the workload of the water heater.

[0107] Steps to increase workload include:

[0108] Increase the operating temperature of the water heater and / or increase the water flow rate of the water heater.

[0109] Specifically, the workload of the water heater can be increased by increasing the set temperature, increasing the water flow rate, or a combination of the two.

[0110] Of course, in actual operation, increasing one of the temperature and water flow rate and decreasing the other can also be used as a way to increase the workload of the water heater.

[0111] In this solution, the workload of the water heater is adjusted by adjusting the set temperature and water flow of the water heater, which can improve the flexibility and accuracy of the workload adjustment of the water heater.

[0112] The following combination Figure 2 , using a specific implementation method to illustrate the implementation process of the method for obtaining fan correction parameters provided by this embodiment.

[0113] First, turn on the water heater and operate it at the lowest operating load (low set temperature, small water flow). After the water heater enters a stable state (the fan speed fluctuation is less than 5% of the average speed within 5 seconds), record the actual speed and working current under the lowest operating load, transmit them to the host computer in real time, save them in the data collection table, and use the actual speed at this time as the initial speed.

[0114] Next, the temperature is raised by 1°C to increase the workload of the water heater. After the water heater enters a stable state (the speed increment fluctuation is less than 10% of the average speed within 5 seconds), the size of the speed increment is determined: (1) If the speed increment is less than 90 rpm, the temperature is further raised by 1°C; (2) If the speed increment is between 90-110 rpm, the current actual speed and operating current are recorded; (3) If the speed increment is greater than 110 rpm, the temperature is reduced by 1°C, and the workload of the water heater is increased by steplessly adjusting the water flow through the water servo until the speed increment is between 90-110 rpm, and the current actual speed and operating current are recorded.

[0115] Gradually increase the working load of the water heater to the maximum operating load, and complete all sampling between the minimum operating load and the maximum operating load.

[0116] It should be noted that the sampling of the working current and the actual rotational speed can also be completed by controlling the working current to change uniformly.

[0117] The method for obtaining fan correction parameters provided in this embodiment adjusts the workload of the water heater by setting the temperature and water flow, so that the actual speed of the fan meets the range of the speed increment, and sequentially obtains a series of linear scattered data of the actual speed and working current, which can improve the accuracy and efficiency of the method for obtaining fan correction parameters.

[0118] Example 3

[0119] This embodiment provides a system for obtaining fan calibration parameters, which is applied to water heaters, such as Figure 3 As shown, the acquisition system includes:

[0120] An adjustment instruction receiving module 1 is used to receive a load adjustment instruction;

[0121] A load adjustment module 2 is configured to adjust the working load of the water heater to a preset load based on the load adjustment instruction;

[0122] The actual speed acquisition module 3 is used to obtain the actual speed of the fan of the water heater under the preset load;

[0123] An acquisition method determination module 4 is used to determine a corresponding correction parameter acquisition method based on the preset speed range to which the actual speed belongs;

[0124] The correction parameter acquisition module 5 is used to acquire a plurality of sets of data on actual rotation speed and working current of the water heater in the correction parameter acquisition mode and use them as fan correction parameters.

[0125] Since the system for obtaining fan calibration parameters provided in this embodiment has the same principle as the method for obtaining fan calibration parameters provided in Example 1, they will not be described in detail here.

[0126] The fan correction parameter acquisition system provided in this embodiment controls the working load of the water heater so that the actual fan speed changes evenly in sequence, and automatically collects the actual speed under different loads and the working current of the water heater as fan correction parameters. On the one hand, it can improve the efficiency of data collection, and on the other hand, it can obtain more accurate fan correction parameters and fit the relationship between the working current and the actual speed under more accurate standard working conditions, so that the state of the fan can be accurately and timely adjusted during the subsequent operation of the water heater, ensuring the water output control of the water heater and improving the user's water use experience.

[0128] Based on Example 3, Figure 4 , this embodiment provides a system for obtaining wind turbine correction parameters.

[0129] In one feasible solution, when the current load of the water heater is greater than the minimum operating load, the load adjustment module 2 is further configured to:

[0130] increasing the current load of the water heater to a preset load according to a first preset load increment;

[0131] or,

[0132] According to the second preset load increment, the current load of the water heater is reduced to the preset load.

[0133] In one feasible solution, when the current load of the water heater is the minimum operating load, the load adjustment module 2 is further configured to:

[0134] According to a third preset load increment, the current load of the water heater is increased to the preset load.

[0135] In one feasible solution, when the current load of the water heater is the minimum operating load, the acquisition system further includes:

[0136] The minimum parameter acquisition module 6 is used to obtain the actual speed and working current under the minimum operating load as fan correction parameters.

[0137] In an implementable solution, the acquisition mode determination module 4 further includes a first determination unit 41 , a second determination unit 42 and a third determination unit 43 .

[0138] If the actual speed exceeds the maximum speed of the preset speed range, the first determining unit 41 is called to determine a first correction parameter acquisition method, the first correction parameter acquisition method corresponding to reducing the workload of the water heater until the actual speed is less than or equal to the maximum speed;

[0139] If the actual speed is lower than the minimum speed of the preset speed range, the second determining unit 42 is called to determine a second correction parameter acquisition method, the second correction parameter acquisition method corresponding to increasing the workload of the water heater until the actual speed is less than or equal to the maximum speed;

[0140] If the actual speed is within the preset speed range, the third determining unit 43 is called to determine a third correction parameter acquisition method, which corresponds to not changing the workload of the water heater.

[0141] In an implementable solution, the first determining unit 41 is further configured to:

[0142] Reduce the operating temperature of the water heater and / or reduce the water flow rate of the water heater.

[0143] The second determining unit 42 is further configured to:

[0144] Increase the operating temperature of the water heater and / or increase the water flow rate of the water heater.

[0145] Since the system for obtaining fan calibration parameters provided in this embodiment has the same principle as the method for obtaining fan calibration parameters provided in Example 2, they will not be described in detail here.

[0146] The fan correction parameter acquisition system provided in this embodiment adjusts the workload of the water heater by setting the temperature and water flow, so that the actual speed of the fan meets the range of the speed increment, and sequentially obtains a series of linear scattered data of the actual speed and working current, which can improve the accuracy and efficiency of the fan correction parameter acquisition method.
