Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a temperature and humidity detection device provided in an embodiment of the present application, including: the device comprises an air temperature detection module 1, a water body temperature detection module 2 and a signal control unit 3; the air temperature detection module 1 and the water body temperature detection module 2 are respectively in communication connection with the signal control unit 3;
the air temperature detection module 1 is used for acquiring a target air temperature in a target environment and transmitting the target air temperature to the signal control unit 3;
the water body temperature detection module 2 is used for acquiring a target water body temperature of a water body in a target environment and transmitting the target water body temperature to the signal control unit 3;

The air temperature detection module 1 and the water body temperature detection module 2 are respectively used for measuring the temperature of the environment where the air temperature detection module and the water body temperature detection module are located. And, air temperature detection module 1 is arranged in carrying out temperature detection to the air in the target environment, and water temperature detection module 2 is arranged in carrying out temperature detection to specific water in the target environment.
The air temperature detection module 1 and the water temperature detection module 2 are respectively in communication connection with the signal control unit 3, and the communication connection mode can be electric connection or wireless connection. And the water body temperature detection module is used for sending the target air temperature detected by the air temperature detection module 1 and the target water body temperature detected by the water body temperature detection module 2 to the signal control unit 3.
The target environment may be an environment in which the temperature and humidity detection apparatus is located when in use.
After the signal control unit 4 obtains the target air temperature and the target water body temperature, the target environment humidity of the target environment can be analyzed according to the target corresponding relationship.
The dry bulb temperature can be the ambient temperature measured by a common mercury thermometer or an alcohol thermometer, namely the dry bulb temperature, which is called temperature for short.
The target wet bulb temperature may be a wet bulb temperature in a target environment. The wet bulb temperature can be a temperature sensing bag of a mercury thermometer wrapped by wet gauze, and becomes a wet bulb thermometer, and the temperature measured by the wet bulb thermometer, namely the wet bulb temperature, reflects the temperature of water on the wet bulb gauze.
The dry bulb temperature and the wet bulb temperature have the following relation with the humidity in the air: the less the water vapor content of the air, the lower the wet bulb temperature, and the greater the difference between the dry bulb temperature and the wet bulb temperature, indicating that the air is drier. Conversely, a smaller difference in wet and dry bulb temperatures indicates a more humid air.
As shown in fig. 2, the target correspondence may be used to indicate the correspondence between the dry-wet-bulb temperature difference, the wet-bulb temperature, and the ambient humidity.
In this embodiment, when the temperature and humidity detection device is in the target environment, the target water temperature detected by the water temperature detection module 2 in the temperature and humidity detection device is similar to the wet bulb temperature.
In any environment, the dry-wet-bulb temperature difference is the difference between the wet-bulb temperature and the dry-bulb temperature, and the reason for the dry-wet-bulb temperature difference is that the humidity of the environment where the air temperature detection module 1 that obtains the dry-bulb temperature is located is the ambient temperature in the target environment is fixed.

For example, if the temperature of the air inlet measured by the air temperature detection module 1 is 35 ℃ and the temperature of the water measured by the water temperature detection module 2 is 26 ℃, the target temperature difference is 9 ℃. And when the signal control unit 3 determines that the temperature measured by the water temperature detection module 2 is approximately the wet bulb temperature, the signal control unit 3 may obtain the target environment humidity of 47% of the target environment according to the wet bulb temperature of 26 ℃ and the first temperature difference of 9 ℃.
Through the temperature and humidity detection device in this embodiment, only need the temperature detection module can carry out temperature and humidity detection, therefore, need not humidity transducer and can reach the purpose of measuring environment humidity, and then, under the condition that does not use humidity transducer, can show the manufacturing cost who reduces equipment, make equipment structure more retrench, the reliability is stronger.
As shown in fig. 3, according to an embodiment of another aspect of the present application, there is provided a temperature and humidity detecting method, including the following steps:
step S101, a target air temperature in a target environment is acquired.
The temperature of the air in the target environment can be detected through the air temperature detection module for detecting the temperature, and the target air temperature is obtained.
The target environment may be an environment in which the temperature and humidity detection apparatus is located when in use.
And S102, acquiring the target water body temperature of the water body in the target environment.
The temperature of the water body under the target environment can be detected through a water body temperature detection module for temperature detection, and the target water body temperature is obtained.
And S103, correcting the target water body temperature to obtain the target wet bulb temperature in the target environment.
The target water body temperature is obtained after the temperature of the water body in the target environment is detected, so that the target wet bulb temperature in the target environment can be obtained according to the target water body temperature analysis after the target water body temperature is obtained.
The target wet bulb temperature may be a wet bulb temperature in a target environment. The wet bulb temperature can be a temperature sensing bag of a mercury thermometer wrapped by wet gauze, and becomes a wet bulb thermometer, and the temperature measured by the wet bulb thermometer, namely the wet bulb temperature, reflects the temperature of water on the wet bulb gauze.
For example: under the condition of meeting the preset precision requirement, directly taking the target water body temperature as the target wet bulb temperature; when the corresponding relation between the water body temperature and the wet bulb temperature is obtained in advance, the target water body temperature can be corrected, and the target wet bulb temperature is obtained.
In step S104, a target temperature difference between the target air temperature and the target wet bulb temperature is determined.
After the target air temperature and the target wet bulb temperature are obtained, a target temperature difference between the target air temperature and the target wet bulb temperature can be obtained by calculating a difference between the target air temperature and the target wet bulb temperature.
And step S105, determining the target environment humidity of the target environment according to the target wet bulb temperature and the target temperature difference.
And after the target wet bulb temperature and the target temperature difference are obtained, the target environment humidity of the target environment can be determined.
Optionally, the corresponding relationship between the wet-bulb temperature, the dry-wet-bulb temperature difference, and the environmental humidity may be predetermined, and then the target environmental humidity of the target environment may be determined according to the corresponding relationship after the target wet-bulb temperature and the target temperature difference are determined.
An environment humidity prediction model can be established in advance, so that the environment humidity prediction model can predict and obtain the corresponding environment humidity according to the input wet-bulb temperature and the dry-wet-bulb temperature difference.
As an optional implementation manner, according to the target correspondence, the step S105 determining the target environmental humidity of the target environment according to the target wet bulb temperature and the target temperature difference includes:
and determining the target environment humidity of the target environment according to the target wet bulb temperature and the target temperature difference, wherein the target corresponding relation is used for indicating the corresponding relation among the dry-wet bulb temperature difference, the wet bulb temperature and the environment humidity, and the dry-wet bulb temperature difference is the difference between the wet bulb temperature and the air temperature in the same environment.
As shown in fig. 2, the target correspondence may be used to indicate the correspondence between the dry-wet-bulb temperature difference, the wet-bulb temperature, and the ambient humidity.
In this embodiment, when the temperature and humidity detection device is in the target environment, the target water temperature detected by the water temperature detection module 2 in the temperature and humidity detection device is similar to the wet bulb temperature.
In any environment, the dry-wet-bulb temperature difference is the difference between the wet-bulb temperature and the dry-bulb temperature, and the reason for the dry-wet-bulb temperature difference is that the humidity of the environment where the air temperature detection module 1 that obtains the dry-bulb temperature is located is the ambient temperature in the target environment is fixed.
As shown in fig. 2, when the ambient humidity is 100%, the humidity of the environment where the air temperature detection module 1 is located also reaches a saturation state, and the dry-bulb temperature is the same as the wet-bulb temperature, so that there is no dry-wet-bulb temperature difference; when the wet bulb temperature is 35 ℃ and the dry-wet bulb temperature difference is 4 ℃, the humidity of the environment where the temperature sensor corresponding to the dry bulb temperature is located is measured to be 75%.
For example, if the temperature of the air inlet measured by the air temperature detection module 1 is 35 ℃ and the temperature of the water measured by the water temperature detection module 2 is 26 ℃, the target temperature difference is 9 ℃. And when the signal control unit 3 determines that the temperature measured by the water temperature detection module 2 is approximately the wet bulb temperature, the signal control unit 3 may obtain the target environment humidity of 47% of the target environment according to the wet bulb temperature of 26 ℃ and the first temperature difference of 9 ℃.
As an alternative implementation manner, as in the foregoing method, the step S103 of correcting the target water body temperature to obtain the target wet bulb temperature in the target environment includes the following steps:
step S201, under the condition that the target environment parameters of the target environment meet preset requirements, determining the difference value between the target water body temperature and a preset correction value.
The target environment parameter may be information indicating an environmental condition of the target environment, such as a temperature, humidity, and the like of the target environment.
The preset requirement may be preset information indicating that the target environment needs to be rectified and is consistent with the parameter type of the target environment parameter.
As an alternative embodiment, the preset requirement may be: the environmental temperature T belongs to [5 ℃,45 ℃) and the environmental humidity W belongs to [ 15%, 95% ]; then when the target environmental parameters meet the environmental temperature T belonging to [5 ℃,45 ℃) and the environmental humidity W belonging to [ 15%, 95% ], the difference between the target water body temperature and the preset correction value needs to be further determined. Moreover, the preset requirement can be obtained empirically, and the target water body temperature needs to be corrected to obtain the numerical range of the target wet bulb temperature.
The preset correction value can be a value obtained according to experience and used for correcting the temperature of the target water body, and optionally, the preset correction value delta T belongs to [0.1 ℃ and 1.1 ℃).
And S202, determining the target wet bulb temperature according to the difference, wherein the ratio of the target wet bulb temperature to the difference is within a preset ratio interval.
After the difference is obtained, the target wet bulb temperature is obtained after the difference is weighted by a preset coefficient. The predetermined ratio interval may be (1, 1.3).
For example, when the target isThe water body temperature is the water tank temperature TWater tankTarget wet bulb temperature TWet ballComprises the following steps:
Twet ball＝k×(TWater tank- Δ T), where k ∈ (1, 1.3)]。
And step S203, taking the target water body temperature as the target wet bulb temperature under the condition that the target environment parameters of the target environment do not meet the preset requirements.
And under the condition that the target environmental parameters of the target environment do not meet the preset requirements, directly taking the target water body temperature as the target wet bulb temperature.
By the method in the embodiment, the target wet-bulb temperature can be determined based on the target water body temperature of the water body, so that the target environment humidity of the environment can be determined according to the target wet-bulb temperature in the later period.
As an alternative implementation manner, as in the foregoing method, the step S103 of correcting the target water body temperature to obtain the target wet bulb temperature in the target environment includes the following steps:
step S301, inputting the target wet bulb temperature and the target temperature difference into a preset environment humidity prediction model.
The environmental humidity prediction model can be obtained by pre-training and is used for obtaining the environmental humidity model according to the wet-bulb temperature and the dry-wet-bulb temperature difference prediction.
For example, several sets of training data may be obtained in advance, where each set of training data includes a corresponding wet-bulb temperature, a dry-wet-bulb temperature difference, and an ambient humidity.
After the target model is trained through the training data, the trained target model is verified through verification data (each group of verification data comprises corresponding wet-bulb temperature, dry-wet-bulb temperature difference and environment humidity), and the trained target model is used as an environment humidity prediction model under the condition that the verification result indicates that the accuracy of the trained target model reaches preset precision.
After the environmental humidity prediction model is obtained, the target wet bulb temperature and the target temperature difference value are input into the environmental humidity prediction model to predict the environmental humidity.
Step S302, the target environmental humidity predicted by the environmental humidity prediction model is obtained.
After the target wet bulb temperature and the target temperature difference are input into the environment humidity prediction model, the structure predicted by the environment humidity prediction model can be obtained, namely the target environment humidity.
By the method in the embodiment, the target environmental humidity corresponding to the target wet bulb temperature and the target temperature difference can be obtained in a model prediction mode.

The first air temperature sensor 101 can acquire the inlet air temperature of the air inlet of the evaporative refrigeration device in a target environment, and transmits the inlet air temperature to the signal control unit 3 through the communication connection between the first air temperature sensor 101 and the signal control unit 3; the second air temperature sensor 102 can acquire the outlet air temperature of the air outlet of the evaporative refrigeration device in the target environment, and transmit the outlet air temperature to the signal control unit 3 through the communication connection between the second air temperature sensor 102 and the signal control unit 3; the water temperature sensor 21 can acquire the water temperature of the water in the evaporative type refrigeration device in a target environment, and transmit the water temperature to the signal control unit 3 through the communication connection between the water temperature sensor 21 and the signal control unit 3.
After the signal control unit 4 obtains the inlet air temperature, the outlet air temperature and the target water body temperature, the inlet air humidity of the air inlet and the outlet air humidity of the air outlet can be analyzed according to the target corresponding relation or the environment humidity prediction model.
Taking the analysis of the inlet air humidity of the air inlet and the outlet air humidity of the air outlet according to the target corresponding relationship as an example:
after acquiring the target water body temperature, the signal control unit 3 may directly use the target water body temperature as the wet bulb temperature in the current environment, or calculate the wet bulb temperature after processing the target water body temperature.
After determining the air inlet temperature, the air outlet temperature and the wet bulb temperature, the signal control unit 3 may calculate a difference between the air inlet temperature and the wet bulb temperature to obtain a first temperature difference; calculating the difference between the outlet air temperature and the wet bulb temperature to obtain a second temperature difference; determining the inlet air humidity of the air inlet according to a target corresponding relation and the target wet bulb temperature and the first temperature difference, wherein the target corresponding relation is used for indicating the corresponding relation among the dry-wet bulb temperature difference, the wet bulb temperature difference and the environment humidity, and the dry-wet bulb temperature difference is the difference value between the wet bulb temperature and the air temperature in the same environment; and determining the air outlet humidity of the air outlet according to the target corresponding relation and the target wet bulb temperature and the second temperature difference.
As shown in fig. 2, the target correspondence may be used to indicate the correspondence between the dry-wet-bulb temperature difference, the wet-bulb temperature, and the ambient humidity.
In any environment, the dry-wet-bulb temperature difference is the difference between the wet-bulb temperature and the dry-bulb temperature, and the reason for the dry-wet-bulb temperature difference is that the humidity of the environment where the air temperature detection module 1 that obtains the dry-bulb temperature is located is the ambient temperature in the target environment is fixed.
As can be seen from fig. 2, when the ambient humidity is 100%, the humidity of the environment where the air temperature detection module 1 is located also reaches a saturation state, and the dry-bulb temperature is the same as the wet-bulb temperature, so that there is no dry-bulb temperature difference; when the wet bulb temperature is 35 ℃ and the dry-wet bulb temperature difference is 4 ℃, the humidity of the environment where the temperature sensor corresponding to the dry bulb temperature is located is measured to be 75%.
For example, if the temperature of the air inlet measured by the first air temperature sensor 101 is 35 ℃ and the temperature of the water measured by the water temperature detection module 2 is 26 ℃, the first temperature difference is 9 ℃. And when the signal control unit 3 determines that the temperature measured by the water temperature sensor 21 is approximately the wet bulb temperature, the signal control unit 3 may obtain the inlet air humidity of 47% of the target environment according to that the wet bulb temperature is 26 ℃ and the first temperature difference is 9 ℃.
If the signal control unit 3 obtains that the temperature of the air outlet measured by the second air temperature sensor 102 is 32 ℃ and the temperature of the water body measured by the water body temperature detection module 2 is 26 ℃, the second temperature difference is 6 ℃. And when the signal control unit 3 determines that the temperature measured by the water temperature sensor 21 is approximately the wet bulb temperature, the signal control unit 3 may obtain the outlet air humidity of 61% in the target environment according to that the wet bulb temperature is 26 ℃ and the first temperature difference is 6 ℃.
