Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a method for acquiring fan correction parameters, which is applied to a water heater, as shown in fig. 1, and comprises the following steps:
s1, receiving a load adjustment instruction;
s2, adjusting the working load of the water heater to a preset load based on the load adjustment instruction;
s3, acquiring the actual rotation speed of a fan of the water heater under a preset load;
s4, determining a corresponding correction parameter acquisition mode based on a preset rotating speed range to which the actual rotating speed belongs;
s5, acquiring data of a plurality of groups of actual rotating speeds and working currents of the water heater in a correction parameter acquisition mode and taking the data as fan correction parameters.
To obtain the fan correction parameters of the water heater, the working current of the water heater and the corresponding linear scatter data of the actual rotating speed of the fan under different loads are obtained under the standard working condition, and the relation between the working current and the actual rotating speed under the standard working condition is fitted to obtain the theoretical rotating speed of the fan.
Specifically, step S1 receives a load adjustment instruction including an instruction to increase or decrease the load. Step S2, based on the instruction of increasing or decreasing the load, the working load of the water heater is adjusted to the preset load, and the working load of the water heater can be adjusted by changing the set temperature, water flow and the like of the water heater. Step S, obtaining the actual rotation speed of the fan under the preset load, wherein the actual rotation speed is the actual rotation speed corresponding to different working loads under the standard working condition and is not equal to the rotation speed of the water heater in actual working.
The preset rotational speed range in step S4 is determined based on the last adjusted actual rotational speed, in order to ensure that the data of the actual rotational speed samples are evenly distributed, and the rotational speed increment is optimal around 100 revolutions/minute. For example, the actual rotational speeds for controlling the multiple samplings are 3000 rpm, 3100 rpm, 3200 rpm, etc., respectively. If the rotation speed increment is too large after the work load is adjusted, the actual rotation speed is directly increased from 3000 rpm to 3190 rpm, and the work load needs to be reduced, so that the actual rotation speed is reduced. Therefore, the corresponding correction parameter acquisition mode comprises the steps of increasing or decreasing the workload of the water heater, enabling the actual rotating speed to be in a preset rotating speed range, acquiring the correction parameters, and directly acquiring the correction parameters without changing the workload.
And S5, acquiring a plurality of groups of actual rotating speeds and working currents as fan correction parameters.
According to the method for acquiring the fan correction parameters, the working load of the water heater is controlled, so that the actual rotating speed of the fan is sequentially and uniformly changed, a series of actual rotating speeds under different loads and the working current of the water heater are automatically acquired to serve as the fan correction parameters, on one hand, the efficiency of data acquisition can be improved, on the other hand, more accurate fan correction parameters can be obtained, the relation between the working current and the actual rotating speed under more accurate standard working conditions is fitted, the state of the fan is accurately and timely adjusted in the operation process of the subsequent water heater, the water outlet control of the water heater is guaranteed, and the water consumption experience of a user is improved.
Example 2
On the basis of embodiment 1, this embodiment provides a method for obtaining fan correction parameters.
In one embodiment, when the current load of the water heater is greater than the minimum operating load, step S2 includes:
according to the first preset load increment, increasing the current load of the water heater to the preset load;
or alternatively, the first and second heat exchangers may be,
and reducing the current load of the water heater to the preset load according to the second preset load increment.
Specifically, when the current load of the water heater is greater than the lowest running load of the water heater, the load can be increased in sequence for sampling, and the load can be decreased in sequence for sampling.
In the scheme, the flexibility of the method for acquiring the fan correction parameters can be improved through different modes for adjusting the workload of the water heater.
In one embodiment, when the current load of the water heater is the lowest operating load, step S2:
and according to the third preset load increment, increasing the current load of the water heater to the preset load.
Specifically, if the current load of the water heater is the lowest operating load, sampling can only be performed by sequentially increasing the load.
In one embodiment, when the current load of the water heater is the lowest operating load, the obtaining method further comprises:
and acquiring the actual rotating speed and working current under the lowest running load as fan correction parameters.
In the scheme, the actual rotating speed and the working current are acquired from the lowest running load, so that the acquisition range of the fan correction parameters can be enlarged, more data which can be used for fan correction can be acquired as much as possible, the accuracy of the fan correction parameters is improved, and the accuracy and the effectiveness of the state of the fan in the running process of the subsequent water heater are ensured.
In one embodiment, step S4 includes:
if the actual rotating speed exceeds the maximum rotating speed in the preset rotating speed range, determining a first correction parameter acquisition mode, and correspondingly reducing the working load of the water heater by the first correction parameter acquisition mode until the actual rotating speed is smaller than or equal to the maximum rotating speed;
if the actual rotating speed is lower than the minimum rotating speed in the preset rotating speed range, determining a second correction parameter acquisition mode, wherein the second correction parameter acquisition mode correspondingly increases the working load of the water heater until the actual rotating speed is lower than or equal to the maximum rotating speed;
if the actual rotation speed is in the preset rotation speed range, determining a third correction parameter acquisition mode, wherein the third correction parameter acquisition mode corresponds to the working load of the water heater.
Specifically, after the workload of the water heater is adjusted in step S2, the actual rotation speed and the working current cannot be immediately acquired as the fan correction parameters. And judging whether the actual rotating speed meets the sampling requirement or not, namely whether the rotating speed increment of about 100 revolutions per minute is met or not.
For example, if the actual rotation speed of the last sampling is 3000 rpm and the rotation speed increment is between 90 rpm and 110 rpm, the preset rotation speed range is between 3090 rpm and 3110 rpm. If the actual rotating speed is greater than 3110 revolutions per minute, the working load of the water heater is reduced; if the actual rotating speed is less than 3090 revolutions per minute, the working load of the water heater is increased; if the actual speed is between 3090 rpm and 3110 rpm, no change in the water heater workload is required.
In the scheme, the actual rotating speed of the fan is controlled to be in a preset rotating speed range, so that the actual rotating speed is sequentially increased or decreased according to a certain rotating speed increment, more uniformly distributed sampling data can be obtained, the accuracy of fitting of subsequent data is improved, and the accuracy of fan correction parameters is improved.
In one embodiment, the step of reducing the workload comprises:
the operating temperature of the water heater is reduced, and/or the water flow rate of the water heater is reduced.
In particular, the workload of the water heater can be reduced by reducing the set temperature, reducing the water flow or a combination of both.
Of course, in actual operation, one increase and the other decrease of the set temperature and water flow can be used as a way of reducing the working load of the water heater.
The step of increasing the workload includes:
the working temperature of the water heater is increased, and/or the water flow of the water heater is increased.
Specifically, the workload of the water heater can be increased by increasing the set temperature, increasing the water flow or a combination of both.
Of course, in actual operation, one increase and the other decrease of the set temperature and water flow can also be used as a way of increasing the working load of the water heater.
In the scheme, the working load of the water heater is adjusted by adjusting the set temperature and the water flow of the water heater, so that the flexibility and the accuracy of the adjustment of the working load of the water heater can be improved.
Next, with reference to fig. 2, a specific implementation procedure of the method for obtaining the fan correction parameter provided in this embodiment is described.
Firstly, starting the water heater to work with the lowest running load (low set temperature and small water flow), after the water heater enters a stable state (the fluctuation of the rotating speed of the fan is less than 5% of the average rotating speed within 5 seconds), recording the actual rotating speed and working current under the lowest running load, transmitting the actual rotating speed and the working current to an upper computer in real time, storing the actual rotating speed and the working current into a data collection table, and taking the actual rotating speed at the moment as the initial rotating speed.
Then, the temperature is increased by 1 ℃ to increase the working load of the water heater, and after the water heater enters a stable state (the fluctuation of the rotation speed increment is less than 10% of the average rotation speed in 5 seconds), the size of the rotation speed increment is judged: (1) If the rotation speed increment is smaller than 90 revolutions per minute, continuously adjusting the temperature to be 1 ℃; (2) If the rotation speed increment is between 90 and 110 revolutions per minute, recording the current actual rotation speed and working current; (3) If the rotation speed increment is greater than 110 revolutions per minute, the temperature is reduced by 1 ℃, and the working load of the water heater is increased by means of stepless water flow adjustment through the water servo until the rotation speed increment is between 90 and 110 revolutions per minute, and the current actual rotation speed and working current are recorded.
Gradually increasing the working load of the water heater to the maximum operating load, and completing all sampling between the minimum operating load and the maximum operating load.
It should be noted that, the sampling of the working current and the actual rotation speed may also be accomplished by controlling the working current to change uniformly.
According to the method for acquiring the fan correction parameters, the working load of the water heater is adjusted through the cooperation of the set temperature and the water flow, so that the actual rotating speed of the fan meets the rotating speed increment range, a series of linear scattered point data of the actual rotating speed and the working current are sequentially acquired, and the accuracy and the efficiency of the method for acquiring the fan correction parameters can be improved.
