Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes in accordance with the embodiments are within the scope of the present invention.
An embodiment of the invention provides a method for acquiring the weight of food materials in a refrigerator, the refrigerator and a computer-readable storage medium.
Fig. 1 is a method for obtaining weight of food material in a refrigerator according to an embodiment of the present application, and although the present application provides the method operation steps described in the following embodiment or flowchart, the method has no necessary cause and effect relation in the steps logically based on the conventional or non-creative labor, and the execution order of the steps is not limited to the execution order provided in the embodiment of the present application.
Specifically, the method comprises the following steps:
step 101: acquiring operation information of a compressor;
in this step, the operation information of the refrigerator 10 includes specific parameters of the operating state and the non-operating shutdown state, and since this embodiment is mainly used to overcome the influence of the magnetic field symmetric retransmission sensor 1 generated when the compressor operates, the case that the compressor is in the operating state is taken as an example to explain, the operation information is obtained in the operation process of the compressor, and the information can be obtained by accessing a PWM signal register of a main control board of the compressor, or can be obtained by detecting the voltage and current of the compressor, and the current operation state of the compressor is judged, and the higher the duty ratio is, the higher the rotation speed is, and the duty ratio is 0 to explain the shutdown. Further, the processing module 2 in the refrigerator 10 acquires the operation information of the compressor.
Step 102: acquiring temperature information of the refrigerating chamber;
in the same refrigerating room with the weighing sensor 1, acquiring temperature information of the environment where the weighing sensor 1 is located, wherein as described in the background art, the weighing sensor 1 generates errors along with temperature fluctuation in a low-temperature environment, and the step detects the temperature information in the current environment;
step 103: acquiring unit weight error information according to the operation information;
the unit weight error information is obtained, the unit weight can be regarded as a standard weight, for example, 1KG or 1 jin, the information means a value corresponding to the weight error of the object when the weight is 1KG, the value can be positive or negative, the value can be positive, when the weighing information per unit is insufficient in the current working state of the compressor and in the current low-temperature environment, for example, the weighing value of the object of 1KG is only 0.9KG, which means that the weighing value is underestimated, the difference needs to be made up, so the unit weight error information is +0.1KG, and the value is negative, when the weighing information per unit is excessive in the current working state of the compressor and in the current low-temperature environment, for example, the weighing value of the object of 1KG is 1.1KG, which means that the weighing value is overestimated, the difference needs to be subtracted, so the unit weight error information is-0.1 KG.
Step 104: acquiring weighing information of food materials;
weighing information is obtained by the weighing sensor 1 who sets up in the bottom of placing the shelf of eating the material, and weighing sensor 1 can weigh eating the material in certain local position, also can weigh whole drawer, and the weighing information that weighing sensor 1 obtained transmits to processing module 2 again, acquires this weighing information by processing module 2.
Step 105: and calculating actual weight information according to the weighing information and the unit weight error information.
The processing module 2 can calculate the actual weight information by combining the weighing information and the unit weight error information, and the judging method is convenient and reliable.
In the above steps, there is no necessary causal relationship between step 101 and step 102, and between step 104 and steps 101 to 103, so that the execution sequence between step 101 and step 102, and between step 104 and steps 101 to 103 is changed without affecting the implementation of the recipe, or some steps are executed synchronously.
When a user needs to obtain specific weight information in the refrigerator, the user may be in any working state at any time, for example, the compressor runs at any power, and is in an environment with a certain low temperature value, and corresponding error conditions are different in different working environments, so that the weighing information obtained in step 104 is compensated in real time through steps 101 to 103, and more accurate weight information is provided for the user.
In the process of producing the refrigerator or debugging the relationship between the unit weight error information and the operation information of the compressor, the method can be performed by referring to the method shown in fig. 2, and specifically, the method comprises the following steps:
and acquiring an operating parameter of the compressor at a certain moment, wherein the parameter can be the operating power Pm of the compressor, when the operating power is within a certain range, continuing to perform the next step, and otherwise, acquiring the operating power again. The significance of meeting the condition that Pmin is less than or equal to Pm and less than or equal to Pmax is to prevent abnormal power from being collected, because a circuit for collecting the power can generate interference, and the circuit can suddenly rise and fall in a waveform to generate an abnormal situation which is particularly large or small, and the limit condition is added to filter abnormal power data so as to facilitate subsequent operations.
The magnitude of the current of the three-phase alternating current of the compressor is constant, and the magnitude of the magnetic field generated at this time can be considered to be constant when the power Pm is operated, but the direction of the magnetic field of the compressor is constantly changed when the compressor is used as a rotating machine, so that it can be considered that a magnetic domain in which the intensity of the magnetic field generated by the compressor is constant but the direction of the magnetic field constantly changes exists in the current state.
The temperature T of the refrigeration compartment in the environment of power Pm is detected.
The method comprises the steps of obtaining current weighing information m of articles with unit weight, wherein the weighing information m of the articles with the unit weight is obtained by a weighing sensor 1, the articles with the unit weight are a certain unit weight, for example, 1kg or 1 jin, and can be obtained by a standard weighing device outside a refrigerator 10, the step detects the weighed weight of the articles with the standard weight under the influence of a magnetic field of a compressor, and m can be more than 1 or less than 1 or equal to 1.
Calculating unit weight error information Δ m-1, Δ m being greater than 0 when m is greater than 1, Δ m being less than 0 when m is less than 1, and Δ m being equal to 0 when m is 1.
The current operating power Pm, the temperature information T and the current Δ m are stored as a set of data in the database S, and are ignored if the data already exists in the database.
By recording a plurality of groups of data of current operating power Pm, temperature information T and current Δ m, a curve with Pm and T as independent variables and Δ m as dependent variables can be fitted, and a functional relation based on the three parameters can be generated.
The above-mentioned running power Pm is equal to the current multiplied by the voltage, and can be obtained by the main control board or the frequency conversion board of the compressor, and the temperature information T is obtained by the temperature sensor 5.
In other embodiments, the operation power Pm may be replaced by an operation rotation speed N of the compressor, and a relationship between the rotation speed N and the unit weight error information Δ m is established, and the specific method may also be as shown in fig. 3, which is not described herein, and the rotation speed of the compressor may be obtained by accessing a frequency on a main control board or a frequency conversion board of the compressor.
In addition, a relation between the duty ratio and the unit weight error information Δ m can be established, a main control board PWM signal register can be accessed, the duty ratio is obtained through data analysis, the unit weight error information Δ m corresponding to the current operation state of the compressor is calculated by obtaining the current duty ratio, and therefore the current actual weight is further judged.
By the method, the corresponding relation between the operation information of the compressor and the unit weight error information can be established and stored in the storage module 3, or the server side acquires the corresponding relation in real time when a user needs to acquire the actual weight.
Based on the above description, in an embodiment, the step of "acquiring the operation information of the compressor" includes:
the method comprises the steps of obtaining operation information of a compressor, wherein the operation information comprises operation power of the compressor.
And the step of acquiring unit weight error information according to the operation information comprises the following steps:
acquiring a functional relation based on parameters of operating power, temperature information and unit weight error information;
and calculating the unit weight error information according to the functional relation among the operating power, the temperature information and the function.
And acquiring the current operating power and the current temperature information when the user needs to acquire the weight information based on the corresponding relation established among the operating power, the temperature information and the unit weight error information of the compressor, and calculating the actual weight. Of course, when the compressor is shut down at this moment, the operating power is 0, and the actual weight may only be combined with compensation based on temperature information.
In other embodiments, the step of "acquiring the operation information of the compressor" includes:
the method comprises the steps of obtaining operation information of a compressor, wherein the operation information comprises rotating speed information of the compressor.
Further, the step of obtaining error information per unit weight according to the operation information includes:
acquiring a functional relation based on the rotating speed information, the temperature information and the unit weight error information as parameters;
and calculating the unit weight error information according to the functional relation among the rotating speed information, the temperature information and the function.
In this step, based on the correspondence relationship between the established rotational speed and temperature information of the compressor and the unit weight error information, the current operating state of the compressor can be determined according to the current rotational speed, and then the current actual weight information is acquired, and of course, when the rotational speed is 0, the actual weight may be compensated only by combining the temperature information.
In both of the above methods, the dependent variable may be obtained by inputting the independent variable based on a certain parameter of the operating state of the compressor and a functional relationship between the temperature information and the unit weight error information. When the power of the compressor is larger, the coil current in the compressor is larger, the generated alternating magnetic field is stronger, the generated induced electromotive force is larger, and the error is larger when the temperature is lower; on the contrary, when the compressor is stopped, the compressor does not generate a magnetic field or the temperature is higher, so the influence is the lowest and the error is the smallest; it can be known that a certain parameter of the operation state of the compressor and the temperature are in a proportional relation with the unit weight error information.
When the functional relationship among a certain parameter of the operation state of the compressor, the temperature information and the unit weight error information is difficult to establish, a form of recording a plurality of groups of data to form a database can be adopted, and when the operation information and the temperature information of the compressor are obtained, the unit weight error information corresponding to the certain parameter and the temperature information included in the operation information in the database is inquired. And (3) constructing a database by using each working state, temperature information and error corresponding to each state of the press, and inputting independent variables and automatically outputting compensation data in the process of compensating the weighing information. That is, the step of "acquiring error information per unit weight based on the operation information and the temperature information" includes:
and acquiring unit weight error information corresponding to the operation information and the temperature information from a database.
Further, the step of calculating actual weight-to-weight information from the weighing information and the unit weight error information includes:
and calculating the actual weight according to the weighing information M and the unit weight error information delta M, wherein the weight information is M (1+ delta M).
In the present embodiment, M and Δ M are in the same unit, for example, in units of kg, g, or jin, and the unit weight error information Δ M may be error information corresponding to each kg, for example, Δ M is 0.1kg, and the weighing information M is 10kg, and M (1+ Δ M) is 10 (1+0.1) and 11kg, and if Δ M is-0.1 kg and the weighing information M is 6.2kg, M (1+ Δ M) is 6.2 (1-0.1) and 5.58 kg. By this method, the actual weight of the article can be calculated.
